Silver King and Mimi's bodies grew bigger, and the blood-red patterns on their bodies became more vivid and beautiful. Xu Xin subconsciously glanced at the map and found that the two guys were still green spots representing their companions, so he breathed a sigh of relief.
He was really afraid that the two guys would cancel the contract after they upgraded, especially Mimi. The mutant beast contract was only effective against low-level mutant beasts. Now it seemed that the increase in strength after the contract would not affect the contract.
After taking two steps, the Silver King suddenly jumped up and pounced on him.
"Bang!"
Xu Xin was thrown to the ground with his back hitting the floor.
"嘤!" Coco was startled and subconsciously wanted to scratch Silver King a few times, but her claws were stuck on Silver King's hair and had no attack effect at all.
Xu Xin did not dodge, he did not feel any malice from the Silver King.
Sure enough, after knocking Xu Xin down, the Silver King licked his face and made a whining sound, like a big dog acting coquettishly.
The two wolf fangs, which looked even thicker and sharper than before, dangled in front of Xu Xin's face but perfectly avoided him.
"Haha, okay, okay!" Xu Xin pushed Silver King's mouth open.
The Silver King is still the same Silver King, but after becoming a mid-level mutant beast, his personality seems to have become more proactive.
Mimi also came over, and the look it gave Xu Xin was much kinder than before. Xu Xin noticed that Mimi's front paws had become sharper, and when it stepped on the floor of the tree house, it even made a few small holes in the floor.
"Mimi, take your claws back and don't poke the floor!" Xu Xin jumped up immediately.
Although the tree house can repair itself automatically, it can't withstand Mimi's step!
Mimi cried out in dissatisfaction.
It had actually retracted half of its claws, but this upgrade made its claws even thinner, longer and sharper than before, so even if it was retracted, it could still cause considerable damage.
It adjusted its posture and slowly retracted a portion of the sharp claws on its claws. Although a portion was still exposed, it would no longer cause damage to the floor of the tree house.
“Huh…” Xu Xin breathed a sigh of relief. At least he didn’t have to worry about Mimi destroying the house when she walked.
Ah Fu also flew over and landed on Mimi.
"Wow, you've grown so big!" Xu Xin was surprised. Ah Fu flapped his wings twice just now, and he found that Ah Fu's wingspan was almost two meters! Moreover, the blood pattern on the inside of the wings was very bright, and it looked very different from before.
Although he didn't know the species of Ah Fu, it was definitely not a very large bat. Ah Fu was already the largest one he had picked out of all the bats, but at first its wingspan was less than one meter, and it still looked a little small when it stood on his shoulder.
But now, my goodness, it was almost catching up with the bald eagle he had seen.
Ah Fu let out a cry. Although its body had grown a lot, its cry was still as sharp as ever.
Xu Xin touched Silver King's head and said jokingly, "Silver King, among the four of you, you are the only one who is not a crying monster."
"Ah!" The Silver King raised his head and shouted.
Isn't it? Koko and Afu are typical crying monsters. Although Mimi is already a giant, its cry is still that of a cat. There is no way. It does not have the vocal structure of the Pantherinae. I am afraid it can only meow in this life.
Xu Xin brought them to the window and told them his plan facing the vines outside.
If you want to get out of this area, you first need a foothold.
He first needs to use explosive arrows to blow up the vines in the area under the tree house to create a foothold, and then take Silver King Mimi down. Then, it will be their time to show their skills.
These blood-thorn vines are just some low-level mutant creatures. Thanks to their large numbers, Silver King and Mimi have now evolved into intermediate mutant beasts. Even their roars can be intimidating to them. It should not be a problem for them to open a path through the vines and rush out.
"Silver King, try to roar again."
"Ah? Woo... Awoo—" Although he didn't understand what Xu Xin was going to do, the Silver King still raised his head and roared.
When the Silver King roared, all the vines under the tree house shrank downwards and became shorter.
It seems that there is no problem. The two beasts are still very intimidating to these blood thorn vines.
Mimi and Silver King are not ordinary intermediate mutant beasts. They are the largest individuals in the population. They are born aliens and naturally powerful. After becoming mutant beasts, they are naturally enhanced on the basis of their own strength.
Not all mutant beasts of the same level are equally powerful. For example, the intermediate mutant wildcat summoned from the altar was slapped to death by a tiger that was not even a mutant beast.
The foundation itself is very important. If you are not strong, your strength will be very ordinary after becoming a mutant beast. Silver King and Mimi are very strong among the intermediate mutant beasts. It should not be a problem for them to deal with the group of vines below.
Xu Xin suddenly thought of the brown bear. Even if it was not a mutant beast, the bear had extremely powerful strength. It was still unknown whether the current Silver King Mimi could fight it.
If he could transform the brown bear into a mutant beast and subdue it, his team's combat effectiveness would definitely increase exponentially. Of course, his appetite would also increase exponentially.
After these two guys got upgraded, their appetites definitely increased again.
Never mind. Now is not the time to think about these things.
Xu Xin came to the weapons and armor manufacturing table, used up all the saltpeter that Li Wenxi had given him before, and added the juice of the mutant vines to make 500 explosive crossbows.
Patting his backpack full of explosive crossbows, Xu Xin felt at ease.
That should be enough.
If you are in a desperate situation, you should use tactical infiltration. If you are successful, you should use firepower coverage. Since you can use firepower coverage, there is no need to waste time on other things. Just blow them up directly!
"Let's go, Coco, you don't have to go, it's very dangerous this time..." "嘤!"
Before Xu Xin could finish his words, Keke interrupted him with a cry, and climbed up his body and onto his shoulder, indicating that it wanted to go too.
"... You have to protect yourself later." "嘤!"
Forget it, just take it with you. Coco has a strong sense of danger, and maybe she can find the "heart" quickly with it.
After putting on his purple-level scale armor suit and eating all the blue-level fruits, and feeling the amplification effect of his body, Xu Xin gained confidence. He first asked the four beasts to wait at the exit, and he reached out to touch the exit of the tree house without hesitation.
Now he was outside the outer wall of the third floor of the tree house, at a height of nearly twenty meters. At this height, he would not be attacked by these vines. He leaned out of the window but was not attacked, which showed that the attack range of the blood-thorn vines was at least not yet at a height of twenty meters.
Xu Xin did not continue to descend. He planned to blast out a foothold below.
Although the blood-thorn vines below could not attack him, they had already sensed that there was an enemy above their heads. The dozen or so vines directly below Xu Xin all stopped swaying naturally in the wind and stood up in a posture ready to go.
It looked like if Xu Xin dared to descend a few meters, they would be thrown directly towards him!
But Xu Xin would not descend. He equipped an explosive crossbow, aimed at the vines, and pulled the trigger.
"Swoosh-" the explosive crossbow shot out like lightning, but the blood-thorn vines were already ready to go. Seeing something coming, several blood-thorn vines swung towards the flying explosive crossbow together and hit the rapidly flying explosive crossbow accurately!
"Boom!" Nu Shi was not blown away by these vines. Instead, the moment he touched the first vine, a violent flame burst out and an explosion sounded at the same time.
The airflow generated by the explosion caused Xu Xin, who was hanging in the air, to shake his body. He quickly controlled the roots to stabilize his body.
The vines that were pulled towards the explosive crossbow were blown into pieces everywhere, and all the vines that were blown were broken into several pieces.
Xu Xin was not in a hurry to send out the next one, as he wanted to see the regeneration ability of these vines.
The smaller pieces of debris had already lost their lives. The large broken vines twisted a few times on the ground. They did not die motionlessly like the previous vines. Instead, they crawled towards the cracks in the ground like a worm and finally inserted themselves into them.
Then, half of the vine began to grow wildly, and within a few seconds, it grew into a new vine. The new vine immediately made a posture ready to go.
After one shot, the number of vines did not decrease, and there were even more.
"... This is indeed a bit disgusting." Xu Xin was speechless. He decided to start covering fire.
With his current strength, it is completely possible for him to quickly string a crossbow in mid-air where there is no force point.
Easily load an explosive crossbow and pull the trigger downwards.
The same scene happened again, but Xu Xin quickly drew the bow and fired again without waiting for them to grow.
This time, another part of the vines whipped over and exploded in the air again.
Then, the third explosive crossbow came again. This time, there were no vines around that could be swung quickly to intercept the crossbow. The explosive crossbow shot directly at the twisting and crawling half-vines on the ground.
"boom!"
These broken vines were bombarded again and finally could not bear it. They were blown into pieces all over the ground without any signs of activity.
But Xu Xin didn't care about that. He never stopped loading the string. He loaded another one immediately after shooting and continued shooting at the ground a few meters below him.
“Boom!” “Boom!” “Boom!” “Boom!”
The explosive arrows exploded one after another, completely clearing a small area on the ground.
"Now!"
Xu Xin quickly returned to the tree house, and Coco jumped onto his shoulders the moment he returned to the tree house. The other three beasts were also waiting at the door, and he quickly descended to the ground with the three beasts.
"Awoo--" The Silver King let out another long roar, causing the surrounding vines that wanted to attack to freeze. Mimi waved its long-extended claws forward without saying a word.
Several cold lights flashed by, and the vines within a two-meter radius in front were instantly cut into broken branches! These broken branches twisted and crawled on the ground, looking for cracks in the ground that they could drill into, trying to be reborn.
Xu Xin didn't want to care about them. Even if he killed them, more vines would appear again. He held a crossbow and said, "Go on, let's rush out!"
The surrounding vines kept trying to attack them, but under the intimidation of the Silver King they dared not act rashly. Within a few seconds, they advanced more than ten meters.
Xu Xin drew out his sword and cut down the vines that were tentatively attacking him, then looked behind him.
The path that had been cleared was covered with vines again. Only then did he discover that the red glow at the roots of these new vines was even brighter.
"This... the more you kill, the stronger you get, right!" Xu Xin gritted his teeth.
But there was no way, he couldn't let them attack him. These new vines didn't seem to be very afraid of the Silver King's threat, and wanted to rush over directly.
Xu Xin raised his hand and fired a crossbow behind him.
"boom!"
The newly grown vines were blown to pieces again and were temporarily unable to attack them.
Mimi kept waving its sharp claws forward to clear the way for them. And looking at Mimi, it didn't seem tired at all. Instead, it would bark every time it waved its claws, and there was a sense of brutality and pleasure in the bark.
The more they tried to walk outside, the denser the vines became. Gradually, the Silver King's long howl could no longer suppress these vines. After all, its cry could only intimidate, not cause harm. Its main attack relied on biting, which required it to go deep into the vines, which was not a good idea.
"Ying!" Coco pointed in a direction and shouted.
Among the vines, a blood-marked vine that was thicker than the surrounding vines suddenly swung towards them!
After Coco's reminder, the Silver King was well prepared. He bit the vine accurately and fiercely. With a "crack", the vine broke, half of the vine fell to the ground, and the remaining half retracted.
With this vine leading the way, the other vines became even more restless.
Suddenly, Ah Fu, who had been in the air, let out a shrill scream, and the vines that were already ready to move suddenly froze. Xu Xin saw that tiny cracks actually appeared on the vines closest to them!
"Well done, Afu!" Xu Xin couldn't help but shout. Now Afu's sonic attack was so effective, and most importantly, it didn't affect him at all!
He didn't dare use the explosive crossbow forward, for fear of accidentally hurting Mimi, so he kept firing the explosive crossbow behind him to stop the attacks of the vines that had become stronger after being reborn.
From time to time, vines would whip him, but his purple-level armor was no pushover. The attacks of low-level mutant creatures were not enough to break through his defenses. As long as he was not tied up and attacked at his weak points, there would be no problem.
"Hurry, we're about to get out!" The explosive arrows in Xu Xin's hand never stopped, and he bombarded the area behind him.
With orderly cooperation, Xu Xin and the four beasts fought their way out of the encirclement of vines and broke out of the siege!
The man and four beasts rushed forward for several dozen meters before Xu Xin turned around to look at the vines.
The vines returned to their original calm, swaying gently in the wind, and the path they cleared was filled with new vines a few seconds later.
The tree house was once again surrounded by dense vines.
Xu Xin took a deep breath.
Now that we are out, the next step is to find the "heart" of the vines!
