The next day, Xu Xin woke up very early.
Today's random boost is the hearing boost, which is also his favorite boost.
If the enhanced vision allows him to grasp the situation in the distance, then the enhanced hearing allows him to perfectly grasp the situation around him.
Even the movement below the ground.
For today's battle, hearing is definitely the most suitable enhancement.
Outside the tree house, all kinds of sounds came into his ears.
There are already quite a few people outside.
It seems that everyone is quite excited because of the upcoming battle.
"I still haven't recovered from this Crystal City and the World Tree! This city is so beautiful!"
"We will win, right? We will win!"
"I'm about to join the battle when I first arrive, but why do I feel so excited?"
"Last night, Mr. Ma Hongwei came to help us install the new tree house heavy crossbow. It felt like the door to a new world had been opened!"
Many survivors from Area 1 came and they were discussing excitedly one by one.
"Of course we will win. You newcomers don't know that the elders of the Explorers have already killed two giant beasts!"
"Behemoth? What is a behemoth?" the survivor from Area 1 asked with some confusion.
Everyone in District 188 knew that Xu Xin had repelled the blood-veined trolls and giant insects, but the people in District 1 were still unaware of it.
Although he only severely injured and repelled the two giant beasts, rumors spread that they had killed the two giant beasts.
However, it was almost over. The troll's body was blown to pieces, and the giant insect's head was also blown off.
I'm afraid these two big guys will never come here again.
"Ah? You don't even know about the giant beast? Ah, my brother from Area 1, um... you must know the monster that Ultraman fought, right? That monster is about the same size!"
"Fuck, is this true? There are still monsters like that?!" the man was shocked.
"Of course it's true! I'm the person involved, I was there, I was in Boss Xu Xin's tree house at the time! The power of that giant cannon is simply invincible! Now we have this Crystal City as a base, we are already invincible, so don't worry!"
"Fuck, I suddenly feel like I'm swelling up!"
“It’s so unreal!”
The words outside reached his ears, making him smile slightly.
He was actually a little worried. Hundreds of new people had arrived yesterday, and if he asked them to participate in the battle today, it might cause dissatisfaction among the people.
But now it seems that compared to their alone and cautious survival, it is much safer for them to fight in this crystal city and under this world tree.
Not to mention that the explorers gave each of them equipment and installed the Tree House Heavy Crossbow.
Their personal strength has increased exponentially. Under such circumstances, they naturally would not be dissatisfied.
but…
The enemies they face today are no match for them before.
Xu Xin washed up quickly and took Coco down the tree house.
Coco had just woken up and was lying on his shoulder, chewing half an apple.
Mimi was also brought down, and the moment she came down, she left like a shadow.
The commander of the outermost first line of defense, the boss of the mutant beasts, is going to the front line.
"It's Master Xu Xin!"
Before Xu Xin had taken two steps, he was discovered by other survivors.
"Don't call me Big Boss, call me Brother Xin!"
"Oh, Brother Xin! Brother Xin is so handsome!"
"This is Xu Xinda... Oh no, this is Brother Xin! He really deserves to be the one who has always been ranked first on the list!"
"Haha, even the mysterious voice that controls everything is now furious with Brother Xin and the others."
"Brother Xin is so handsome... Is he still in need of a woman?" a girl asked in a low voice.
"Don't even think about it. Brother Xin has a lot of women around him, and they are all beautiful." The survivor from Area 188 whispered.
Xu Xin was speechless.
Although there were indeed many women in Suoran's team, the only one who actually had that kind of relationship with him was Li Wenxi.
Xu Xin's tree house was in the ravine, while the group of people were outside the ravine, not very close. The people over there thought Xu Xin couldn't hear them, so they were whispering.
A piece of iron plate was laid on the gully as a bridge, so that Xu Xin could easily cross the five-meter-wide gully. Of course, this iron plate would be taken back after the battle began.
He walked across the ravine and came to the depths of the crowd, and these people stopped talking.
Facing Xu Xin at such a close distance, they were still a little reserved. At the same time, their eyes were full of respect when they looked at Xu Xin.
"How is it? Are you getting used to living here?" Xu Xin walked forward and said with a smile, "The conditions here should be pretty good."
"Adapted, of course adapted!" Seeing Xu Xin's friendly attitude, the others were no longer restrained and gathered around him.
"I've adapted so well! I've never felt so safe!" a sturdy man said with his legs raised, "This is simply heaven!"
Xu Xin smiled and said, "Just adapt. Since you have chosen this side, we will not let you suffer any loss. However, don't be too confident. Today's battle is not as simple as you think."
Xu Xin's words made everyone look at each other in bewilderment.
The strongest survivors said so, and they began to become serious and nervous.
"Remember, in today's battle, do not come out of the tree house until it is destroyed. The crossbows assigned to each of you must be used in a planned manner. Do not use them too quickly, and do not be reluctant to use them. If your tree house is in danger of being destroyed..."
Xu Xin pointed to the crystal house next to him and said, "The crystal house is indestructible. You can hide in it."
Everyone nodded very seriously.
"I understand, Brother Xin!"
"Got it, I'll tell the others!"
Xu Xin nodded, turned around and walked back.
The line of defense for this group of survivors was in the form of tree house crossbows providing fire coverage to the beast herd.
It was enough to scatter the herd.
As for after the explosive crossbows were used up, their own combat power was not strong, so there was no need to take risks.
Behind me, I could hear the survivors discussing.
"The Crystal House is actually indestructible!?"
"Yes, it is said that the purple-grade steel weapons of the elders were all chopped into pieces, but the Crystal House was not harmed at all."
"So strong?! Then we can just use the crystal house as a fortress..."
"No, the tree house heavy crossbow needs to be installed on the tree house."
"That's right. Hey, it would be nice if there were weapons that could be placed in the crystal house."
"Of course there will be. Isn't it because this siege came too quickly and the elders didn't have time to make it?"
"That's true, haha, I feel like the explorers really know everything!"
"Anyway, we just need to complete our own mission. Listen to Brother Xin and don't leave the tree house."
"I'm not afraid. I have strong fighting ability. I will protect the World Tree together with the elders!"
"Haha, I've killed a few mutant creatures before. Even if my crossbow is exhausted, I still think I'm a very strong fighter!"
"Didn't they say that Crystal City would make all mutant creatures submit? There shouldn't be much danger in the city, right?"
…
Back at his tree house, Xu Xin was about to go back inside when Lou Feier poked her head out of her tree house and said, "Xu Xin, come over for breakfast!"
Xu Xin was pulled into the tree house by her, and Zeng Tao and Jin Yue were also there.
"Where's Shi Wanyun?"
Xu Xin didn't see Shi Wanyun, so he asked.
"She went back to sleep in her own tree house last night." Lou Feier brought breakfast to the table. "She said that her own tree house had a random amplification effect. She might as well go back to sleep in her own tree house instead of sleeping here, so she teleported back directly."
That's okay.
But, it is true.
Last time, Shi Wanyun told her that the decoration level of her tree house had reached 500 points, which meant that she could also obtain a random enhancement and choose a historical enhancement at the same time.
The benefits of sleeping in your own tree house are indeed the greatest.
However, it was easy for her to go there, but coming back was not a matter of teleporting.
Xu Xin didn't have a teleportation device, so she needed to teleport from the teleportation array on her side to the teleportation array at the edge of the Crystal City here, and then walk back.
It's a bit troublesome.
It seems that when Wen Xi comes back, he will need to make a few more coordinates.
Let’s forget about it for now, after all, the coordinates require a lot of materials.
"So she still has time to come over?" Zeng Tao asked incoherently with her mouth full.
While eating breakfast, Xu Xin sent a call request to Shi Wanyun.
The call was connected immediately, and before Xu Xin could say anything, she explained, "I'm already in Crystal City, and I'll be there soon."
A map appeared in Xu Xin's mind. Sure enough, a few hundred meters away from the teleportation array, there was a green light moving towards Xu Xin. It should be Shi Wanyun.
"I see."
After hanging up the phone, Xu Xin finished his breakfast.
"It's already seven o'clock." Lou Feier raised her hand to check the time. "In an hour... the enemy will attack."
"Yeah." Xu Xin stood up and picked up Coco who was still chewing an apple. "I'm going to go back first. You guys should go back to your tree houses and wait."
Back in his tree house, Xu Xin looked up at his watch and found that he had been added to a group.
It's a group called Crystal City Survivors.
There are 248 people in the group. It seems that all the survivors in Crystal City have been pulled into this group.
This kind of thing is usually done by Ji Chaoyang.
Ji Chaoyang also posted some precautions in the group, which were similar to what Xu Xin had just said.
Qi Xuefei: "Everyone should have received two pills. This pill is the latest result of a recent development. It can be taken in advance and lasts for about two hours. Any injuries sustained within these two hours can be healed.
However, the effect of the pill has an upper limit. Multiple minor injuries within two hours can be quickly recovered, but a fatal injury will exhaust the effect of the pill. There are no side effects. "
Qi Xuefei has new research results.
The watch vibrated, and Qi Xuefei also initiated a transaction with Xu Xin.
However, she gave Xu Xin a whole bottle, which contained ten pills.
This is a good thing.
Take it in advance and it will take effect automatically. You don't have to worry about whether you will have the consciousness and ability to take the pills after being seriously injured.
This is just like Lou Feier and the others’ near-death explosion, they truly have an extra life!
"You can only take one pill a day. Everyone, you must consider the time you take the pill. You can also take it after you are injured. The effect of taking it after an injury is basically the same as the previous pill, so try to take ordinary pills after an injury."
Qi Xuefei explained again in the group.
Xu Xin held the medicine bottle, his eyes shining slightly.
It can only be taken once a day, and the effects last for two hours.
Although not as reliable as the near-death burst, it is still very strong.
Most importantly, there are no side effects and no debilitating effects.
And at this moment, Xu Xin's face changed.
On the map in his mind, several red dots suddenly appeared around Crystal City.
Immediately afterwards, countless red dots appeared wildly around the Crystal City!
In just three or four seconds, the entire Crystal City was surrounded by extremely dense red light spots!
These red dots appear suddenly.
Teleport again!
"Be careful, the beast tide is coming!"
Xu Xin immediately warned everyone in the Crystal City survivor group, "Crystal City has been surrounded!"
Outside the Crystal City, the green spots of light began to move.
Those mutant creatures that were instigated by the Crystal City began to walk out of the Crystal House, intending to defend the Crystal City!
"I see, we are surrounded on all sides!" Ji Chaoyang also said in the group, "I'm afraid the first line of defense won't hold out for long. Everyone, get ready, we're about to fight!"
Ji Chaoyang’s improvement today should include an improvement in his vision.
Everyone immediately responded in the group.
Xu Xin saw that the heavy crossbows on the surrounding tree houses were adjusting their directions one by one and pointing them towards the outside of the Crystal City.
All the heavy crossbows were adjusted together in an orderly manner, giving it a real army-like feel.
As soon as the enemy comes in, these heavy crossbows will shoot deadly shots!
Xu Xin immediately contacted Qin Fu: "You are in your tree house now, right?"
"It's in the tree house," Qin Fu said immediately, "My perception range is limited, and I can't sense the situation outside the Crystal City."
"That's good. You don't need to run outside. If there is any situation below the ground near the World Tree, let us know immediately."
"Understood."
Qin Fu’s task was not to sense the surrounding beasts. There was no need for him to sense them at all.
They had to rely on his ability to sense the movements of the enemy burrowing underground.
Because he is the only one who can clearly grasp the situation underground!
Therefore, a circle of ordinary trees were planted around the World Tree to facilitate Qin Fu's exploration of the surroundings.
Silver King and Ah Fu also came over.
"Afu, if there are any enemies in the air, use your voice to shake them down."
Ah Fu, whose wingspan exceeded two meters, flapped his wings twice and made a shrill cry.
"Silver King, follow me."
With the Silver King around, he has superb mobility.
“Ouch!”
"嘤!" Coco climbed onto the windowsill and looked outside.
And at this moment, the red dots around Crystal City moved.
They rushed towards the Crystal City like a tide!
In an instant, the periphery of Crystal City was surrounded!
After entering the Crystal City, the red dots did not slow down and continued to pour into the city!
"Sure enough, this group of beasts will not be affected by the Crystal City." Xu Xin narrowed his eyes, "A mutant creature without the blood of a giant beast!"
At the same time, the dense green dots outside Crystal City instantly collided with the red tide!
The brightness of these red light spots is generally dimmer than that of the green light spots.
After all, the overall strength of the mutant creatures on the periphery has been improved after the baptism of Crystal City over the past two days. According to Wen Guixin, their sizes have all increased a lot.
With the dual blessing of blood pattern mutation and giant beast blood, it is reasonable for them to be stronger.
But... this time the beast tide is even denser than last time! There are even more of them!
The green light spot was instantly submerged by the red light spot!
Of course, these green spots did not disappear, but started fighting in the red tide!
It can be seen that the number of red light spots around each green light spot is constantly decreasing.
The advance of the red wave was blocked in an instant!
"Good job, Mimi." Xu Xin whispered.
However, this first line of defense alone cannot always stop the overall advance of the beast tide.
The number of red light spots has indeed decreased, but it is still dense!
Although the green light spots are brighter and the countless red light spots are rapidly dimming,...
The gap in numbers between the two sides is just too big!
As enemies continued to pour in, the number of green spots began to slowly decrease.
At this time, on the battlefield in the north, large areas of red light spots were dyed green. At the same time, the green color quickly expanded towards the red group like a virus!
It was Wen Guixin who took action!
The enemy mutant creatures over there have been infected by her!
Her ability is still the most effective way to deal with the beasts!
But... the battle line is too long.
The length of the entire city edge is nearly twenty kilometers.
Although the north is dominated by Wen Guixin's ability, other locations cannot be invaded so quickly!
And at this moment, the other party seemed to have discovered the problem.
As a result, the actions of the red spots changed!
They no longer fought with the green spots of light, but rushed towards the World Tree frantically!
It seemed that they only had one goal left, which was to approach the World Tree as quickly as possible!
Friendly mutants are much less stressful and kill enemies faster, but...
The speed of the red wave influx instantly increased!
Countless red spots of light directly crossed the green defense line and rushed towards the World Tree!
"Everyone, it's time for you to show your skills!" Xu Xin immediately said to the crowd, "In one minute, a tide of mutant beasts will come over. Make good use of the control panels and heavy crossbows in your tree houses!"
"Damn, they run too fast!" Wen Guixin cursed in the group.
"Come back soon. The closer you are to the World Tree, the more concentrated the beasts will be, and the stronger your abilities will be!" Xu Xin immediately said to Wen Guixin.
"Okay! I'll go back now!"
Wen Guixin mounted an infected leopard and quickly rushed back.
Xu Xin was watching the front line nervously.
He could already clearly see countless mutant creatures moving around in the Crystal City.
At this moment, he suddenly discovered that a dark mass appeared in the eastern sky...
"Everyone, pay attention to the sky! Flying mutants are coming!"
In the group, Ji Chaoyang issued a warning at the same time.
The flying mutant creatures are here as expected!
