"Try diving into the water." Xu Xin suggested.

Xu Xin had no good way to kill these bugs, so he could only let him dive into the water to hide.

He just felt that these flying insects were difficult to deal with, so he blew them up with the flowers at the beginning. Now it seems that this is indeed the best choice.

Wang Lei: "I know! Ah ah, I'm so far away from the creek now!"

Xu Xin shook his head and continued walking out of the cave.

From a distance of hundreds of meters, Xu Xin saw that the entrance to the cave was blocked by the collapsed ground. It was the three explosive arrows just now that shook the soil at the entrance.

But it doesn't matter, it's all soft soil. Silver King and Mimi dug away the soil blocking the road in a few times, and one person and four animals appeared in the sun again.

Xu Xin turned on the wolf and headed towards the nearest of the remaining two caves, which was the cave he and Coco 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 entered. It seems that the effect of this red mist on mutated beasts is not only to enhance their strength.

There were signs on the map, and the distance between the two caves was only a few hundred meters, so they arrived in just a few dozen seconds.

After getting off the wolf, Xu Xin looked around the hole again, 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 go straight down.

Before going down, he took another look at the information in [Explorer]. Wang Lei didn't speak anymore, but Wen Guixin did.

"I just came out of a cave. There was no heart inside, nor was it the flower you mentioned. Instead, there was a mutated beast like a pangolin, as big as a wild boar."

Are there mutant beasts again?

"Did you kill it?" Xu Xin asked.

Wen Guixin: "No, this beast knows how to drill holes. It spotted me from a long distance away and burrowed directly into the ground and ran away. I ran forward and found that it had already drilled very deep. I was in this hole

I didn’t get anything out of it, but I didn’t encounter any danger.”

A mutated beast that can burrow?

Xu Xin: "Is the hole it drilled very big?"

Wen Guixin: "Hmm...less than one meter in diameter?"

It will run away when seeing people, so it seems to be a low-level mutated beast. If Xu Xin can encounter it, he can try to use the mutated beast contract to tame it. Mutated beasts that can dig holes are rare, so they should be of great use.

One person and four beasts continued to line up in formation and entered the cave in front of them.

The entire cave wall is still composed of dry light red contaminated soil. After the last experience, Mimi, who was walking in front, was no longer so careful, but relaxed and started to move forward quickly.

After advancing about a few hundred meters, Xu Xin noticed something strange.

"Huh?" He felt like he heard something, but he couldn't hear it clearly.

As he continued to move forward, the faint voice gradually became clearer in his ears.

"thump……"

His eyes gradually widened and he listened carefully.

"Thump...thump..."

Xu Xin's face showed a hint of joy.

It’s the sound of heart beating!

It seems that this is the cave!

"Be careful, that big guy is deep in this cave!" Xu Xin reminded Mimi and Ah Fu in front.

The two beasts barked twice in response, Mimi's steps became cautious, and 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, and it has even overlapped with those dense red light spots.

Now, above their heads are those bloody thorn vines that can regenerate infinitely!

"Plop! Plop!"

The sound of the heart beating became more and more obvious, and it was almost exactly the same as the sound heard in the video.

There is a corner three or four meters in front of them, and the heart is on the other side of the corner. Mimi walked forward to the corner and stopped.

Xu Xin held a crossbow, walked forward in two steps, and looked to the other side of the corner.

"Ugh!" Coco on her shoulder exclaimed in a low voice.

"call……"

Xu Xin breathed out, clenched his fists, and showed a slightly scared and excited smile on his face.

It is another underground space like a hall, with vines growing randomly everywhere.

In addition to the blood-thorn vines and blood-striped vines, there are also some ordinary vines without any patterns, which are messily intertwined with the mutant vines, forming a sphere as a whole.

And the center of the sphere, wrapped in 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, reaching a height of six to seven meters, and the vines wrapped around it are three layers inside and three outside, reaching a height of nearly ten meters.

The entire underground space was completely filled with this vine ball. The nearest vine was only five or six meters away from the corner where Xu Xin was.

However, something different is that although this "heart" is beating constantly, it does not emit the brighter red light in Ji Chaoyang's video, nor does it flicker with the beating. Similarly, the surrounding

The vines are also dull.

In addition, there is no Red Mist Flower. Although there is always a faint strange fragrance floating in the cave, there is no red mist. Silver King Mimi has not been strengthened, and the blood patterns on her body have not lit up red. The entire cave is still the same.

It was pitch black.

The intertwined vines are different from those swaying in the wind on the ground. They are in a completely still state. If most of their branches did not have patterns or blood thorns, Xu Xin would even think that they are very ordinary plants.

.

Only the piece of red flesh in the middle was beating slowly and rhythmically, making a "thump, thump" heartbeat sound.

In this dark and airtight environment, the beating sound seemed extremely heavy. Every beat seemed to make Xu Xin's heart skip a beat, and he even felt like his head was starting to feel dizzy.

The sound of this heart beating can actually affect him. His mental power has not yet increased in time!

It suddenly occurred to him that he had not eaten strawberries (blue) in the tree house.

Strawberries can eliminate all negative effects and maintain emotional stability for half an hour.

Xu Xin actually doesn't really want to use blue-grade strawberries. After all, this thing is too similar to something and feels addictive.

But now he couldn't worry about so much. He quickly took out a strawberry from his backpack and ate it. Instantly, his dazed mind became much clearer, and his slightly nervous and excited mood also calmed down.

Xu Xin took the four beasts back outside the corner and ate all the blue-level fruits again to ensure that all the buffs on himself were there.

"Hey..."

Xu Xin felt that Coco's body was a little stiff on her shoulders.

It was very wary of the heart in front of it. Now their position was directly below the tree house. This piece of meat that looked like a heart was the thing that had scared Coco for a whole day.

Based on the distance they just walked, they are now about three to four hundred meters underground.

"You guys, stay here and don't move. I'll go in and take a look first." Xu Xin put Coco on her shoulders onto Silver King's back and whispered to the four beasts.

The entire interior cannot be seen at the entrance of the cave, so he needs to enter it and observe it carefully with his enhanced eyes, so as not to let Mimi enter and test it first, otherwise it will be bad if it touches this heart.

All four beasts responded with a slight cry.

Xu Xin did not dare to act rashly. It was after encountering this heart that Ji Chaoyang suddenly lost contact on the way back. Although his name was not forgotten, he must have been in danger.

Gently, step by step, following the rhythm of his heart, Xu Xin stepped into an underground space, and the entire space was completely presented to him.

He noticed the difference immediately.

After walking a few hundred meters into the cave, the walls of the cave were composed of contaminated soil, but the soil in all directions in this space was very ordinary soil, not even green grade, but white grade barren soil.

It seems that the heart and these vines have not polluted the soil below the tree house.

The heart is about six or seven meters high and is surrounded by three layers of messy vines. The layers of vines surrounding the heart are about three to four meters thick. If you want to use spears and explosive crossbow bolts to directly

It is impossible to attack them, as they will only be covered by vines.

However, Xu Xin also has another weapon.

Burning Arrow!

With so many vines, if you use a burning arrow, you can burn a large area! Because they are not on the ground, they will not cause jungle fires, which is perfect!

Xu Xin had made forty flaming arrows before, and now they are all in his backpack. Forty arrows are completely enough.

Of course, there are disadvantages. Burning will consume a lot of oxygen and produce thick fog. After igniting these vines, he needs to run out immediately. If he continues to stay underground, he will only suffocate to death.

That’s it!

Xu Xin slowly backed away.

Suddenly, the heart protected by layers of vines lit up with a blood-red light!

Xu Xin's pupils shrank.

"Hey!" Coco's anxious cry came from behind. The meaning of the cry was very clear. It was telling him to get out of there quickly. Danger is coming!

Resisting the urge to raise his hand and shoot an arrow, Xu Xin quickly returned to the corner, hiding in a relatively safe place and looking towards his heart.

The frequency of the beating has obviously accelerated, and the blood-red light on the heart begins to flicker in and out with the beating!

As the heart beats, the vines around the heart began to glow red, and the patterned blood thorns on the body began to twist.

This scene is exactly the same as the one in the video! The red light shines in the entire underground space, completely dyeing the surrounding area blood red, making people shudder.

"Hiss - that's..."

In addition to the blood-striped and blood-thorned vines, there are also some ordinary vines in this space. Under Xu Xin's gaze, patterns and blood-thorns began to grow!

These vines actually transformed into mutated vines with the beating of the heart!

"Hey!" Coco's cry was full of anxiety.
Chapter completed!
