"Try jumping into the water," Xu Xin suggested.
Xu Xin didn't have any good way to kill these insects, so he could only jump into the water to hide.
He felt that these flying insects were difficult to deal with, which was why he blew them away along with the flowers in the beginning. Now it seems that this was indeed the best choice.
Wang Lei: "I know! Ah, I'm so far away from the stream now!"
Xu Xin shook his head and continued walking out of the cave.
From hundreds of meters away, Xu Xin saw that the entrance of the cave was blocked by collapsed ground. It was the three explosive arrows that had caused the soil at the entrance to collapse.
But it didn't matter, it was all loose soil, and Silver King and Mimi dug up the soil blocking the road in a few moves, and the man and four beasts appeared in the sun again.
Xu Xin climbed onto the wolf and headed towards the nearest of the two remaining caves, which was the cave he and Coco had discovered.
Perhaps because they inhaled a lot of red mist in the cave, Silver King Mimi and Ah Fu were obviously more excited and active than before they went in. It seems that the effect of this red mist on the mutant beasts is probably more than just enhancing their strength.
According to the map markings, the distance between the two caves was only a few hundred meters, so they arrived in just a few tens of seconds.
After getting down from the wolf's body, Xu Xin observed the surroundings of the burrow again. He squatted down and grabbed a handful of soil, but still found nothing different.
Forget it, the boat will naturally go straight when it reaches the bridge, so let’s just go down.
Before going down, he took another look at the information in the explorer. Wang Lei didn't speak again, but Wen Guixin spoke.
"I just came out of a cave. There was no heart inside, nor was it a flower as you said. Instead, there was a mutant beast that looked like a pangolin, as big as a wild boar."
Another mutant beast appeared
"Did you kill it?" Xu Xin asked.
Wen Guixin: "No, this beast can dig holes. It spotted me from a long distance away and ran away directly into the underground hole. I ran forward and found that it had already dug very deep. I didn't get anything in this hole, but I didn't encounter any danger."
A mutant beast that can burrow
Xu Xin: "Is the hole it drilled very big?"
Wen Guixin: "Hmm... less than one meter in diameter?"
It would run away when it saw people. It looked like a low-level mutant beast. If Xu Xin could encounter it, he could try to subdue it with the mutant beast contract. Mutated beasts that could dig holes were rare, so they should be very useful.
The man and four beasts continued to form a formation and entered the cave in front of them.
The walls of the entire cave were still made of dry, reddish polluted soil. With the experience from last time, Mimi, who was walking in front, was no longer so careful, but instead loosened her pace and began to move forward quickly.
After walking about a few hundred meters, Xu Xin noticed something strange.
"Hmm?" He thought he heard some sound, but he couldn't hear it clearly.
Continuing forward, the faint sound gradually became clearer in my ears.
"Plop..."
His eyes gradually widened and he listened carefully.
“Plop… plop…”
A hint of joy appeared on Xu Xin's face.
It's the sound of a beating heart!
It seems that this is the cave!
"Be careful, the big guy is deep in this cave!" Xu Xin reminded Mimi and Afu in front.
The two beasts barked twice in response. Mimi's steps became cautious, and the Silver King also walked to Xu Xin's side to protect him.
Xu Xin has been paying attention to the map. Their current location is very close to the tree house, even overlapping with those densely packed red spots of light.
Now, above their heads are those blood-thorn vines that can regenerate infinitely!
“Plop! Plop!”
The sound of the heartbeat became more and more obvious, and it was almost exactly the same as the sound heard in the video.
There was a corner three or four meters ahead of them, and the heart was on the other side of the corner. Mimi walked to the corner and stopped.
Holding a crossbow, Xu Xin took two steps forward and looked to the other side of the corner.
"Ah!" Coco on my shoulder exclaimed in a low voice.
"Huh..."
Xu Xin exhaled, clenched his fists, and a smile that was a bit scared and a bit excited appeared on his face.
It was another underground space that looked like a hall, with vines growing randomly everywhere.
In addition to the blood-thorn vines and blood-patterned vines, there are also some ordinary vines without any patterns, which are intertwined with the mutated vines in a messy way, forming a sphere as a whole.
And in the center of the sphere, wrapped within it, is what Xu Xin has been looking for, the huge beating piece of meat, the blood-red "heart" that has been providing energy to the blood-thorn vines on the ground!
This heart is extremely huge, about six or seven meters high, and the vines wrapped around it are three layers inside and three layers outside, reaching a height of nearly ten meters.
The entire underground space was filled with this vine ball. The nearest vine was only five or six meters away from the corner where Xu Xin was.
However, there was a slight difference: although this "heart" was beating constantly, it did not emit the bright red light shown in Ji Chaoyang's video, nor did it flicker with the beating. Similarly, the surrounding vines were also dim.
In addition, there was no red mist flower. Although there was a faint strange fragrance floating in the cave, there was no red mist. Silver King Mimi was not strengthened, and the blood patterns on his body did not glow red. The entire cave was still pitch black.
The intertwined vines are different from those on the ground swaying in the wind. They are in a completely still state. If most of them did not have floral patterns or blood thorns on their branches, Xu Xin would even think that they were very ordinary plants.
Only the piece of red flesh in the middle was beating slowly and rhythmically, making a "thump, thump" sound of a heart beating.
In this dark and enclosed environment, the sound of the drum seemed extremely heavy. Every beat seemed to make Xu Xin's heart skip a beat. He even felt his head starting to feel dizzy.
The sound of the beating heart could actually affect him, but the time had not yet come for his mental strength to increase!
It suddenly occurred to him that he had never eaten strawberries (blue) in the tree house.
Strawberries can eliminate all negative effects and maintain emotional stability for half an hour.
Xu Xin actually didn't really want to use blue-level strawberries. After all, this thing was too similar to something else and it felt addictive.
But he couldn't worry about so many things now. He quickly took out a strawberry from his backpack and ate it. In an instant, his dizzy head became much clearer, and his slightly nervous and excited emotions also calmed down.
Xu Xin led the four beasts back to the corner and ate all his blue-level fruits again to make sure that all the buffs on his body were still there.
"Hmm..."
Xu Xin felt that Coco's body on his shoulder was a little stiff.
It was very wary of the heart in front of it. Now they were right below the tree house, and this piece of meat that looked like a heart was what had frightened Coco for a whole day.
Based on the distance they had just covered, they were now about three or four hundred meters underground.
"You guys, stay here and don't move. I'll go in and take a look first." Xu Xin carried Coco from his shoulders to the Silver King's back and whispered to the four beasts.
He couldn't see the whole picture inside the cave from the entrance, so he needed to go in and observe carefully with his amplified eyes. He didn't let Mimi go in first to test it, as it would be bad if she touched the heart.
All four beasts responded with a soft cry.
Xu Xin did not dare to act rashly. Ji Chaoyang suddenly lost contact on his way back after encountering this heart. Although his name has not been grayed out, he must have been in danger.
Gently, step by step, following the rhythm of his heartbeat, Xu Xin stepped into an underground space, and the entire picture of the space appeared completely in his eyes.
He noticed the difference immediately.
After walking in the cave for several hundred meters, we found that the walls of the cave were made of contaminated soil, but the soil on all sides of this space was very ordinary soil, not even green level, but white level barren soil.
It seems that this heart and these vines have not yet contaminated the soil under the tree house.
The heart is about six or seven meters high and is surrounded by three layers of messy vines. The vines surrounding the heart are about three or four meters thick. It is impossible to attack them directly with spears and explosive crossbows, as they will only be blocked by the vines.
However, Xu Xin has another weapon.
Burning Arrow!
With so many vines, if you use a burning arrow, you can burn a large area! Because it is not on the ground, it will not cause a jungle fire, which is perfect!
Xu Xin had made forty burning arrows before, and now they were all in his backpack. Forty arrows were more than enough.
Of course, there are disadvantages. Burning will consume a lot of oxygen and produce thick fog. After lighting these vines, he needs to run outside immediately. If he continues to stay underground, he will suffocate to death.
Just do it!
Xu Xin slowly backed away.
Suddenly, the heart protected by layers of vines lit up with a blood-red light!
Xu Xintong's eyes shrank.
"嘤!" Coco's anxious cry came from behind. The meaning of the cry was very clear. She was telling him to leave there quickly because danger was coming!
Resisting the urge to raise his hand and shoot an arrow, Xu Xin quickly returned to the corner, hid in a relatively safe place, and looked towards the heart.
The frequency of the beating obviously increased, and the blood-red light on the heart began to flicker with the beating!
The vines around the heart began to glow red and slowly twisted as the heart beat.
This scene is exactly the same as the one in the video! The red light shines throughout the underground space, dyeing the surroundings completely blood red, which makes people shudder.
"Hiss—that's..."
In addition to the blood-patterned and blood-thorned vines, there were also some ordinary vines in this space. Under Xu Xin's gaze, they began to grow patterns and blood thorns!
These vines actually transformed into mutated vines with the beating of the heart!
"Oh, oh, oh!" Coco's voice was full of anxiety.
Danger! Very dangerous!
