Slowly walking forward in the cave, Xu Xin began to observe the surroundings.

The cave wall is not stone, but some dry soil. The soil is light red. The entire cave wall is composed of this light red contaminated soil (ash).

He touched it lightly with his hand, and a small piece of the wall broke into pieces, fell to the slope, and rolled down a distance.

"You guys, please don't touch the wall. It's made of dirt and may collapse." Xu Xin reminded the four beasts.

The underground passage inside this underground cave is rounded from the bottom to the top. Although the ground is sloped, it is relatively flat, while the top is arc-shaped.

The entire cave seemed to have been drilled by a giant insect, all the way underground.

"Hey..." Coco lay on Xu Xin's shoulder, shrinking her head in fear.

It has a very keen sense of danger, and in its perception, they are approaching danger step by step.

Xu Xin naturally knew that there was danger ahead, but he still had to move forward. Now his treehouse was surrounded by mutant vines. He couldn't even save the treehouse without destroying the heart.

Logically speaking, this road should be less than a kilometer away, but he felt that he had walked for a long time. The further down he went, the quieter it became, and the surrounding area was already so dark that he could hardly see his fingers. Fortunately, Xu Xin had night vision.

It won't have much impact on him.

As mutant beasts, Mimi and Silver King can see at night in a dark environment. Although Coco is not a mutant beast, for some reason, he has never been affected by a dark environment. Not to mention bats, which can

Positioning based on the ultrasonic waves emitted is completely unaffected by darkness. Darkness is its home field.

In the cave, only the sound of their footsteps was heard.

Although his nose had adapted to the surrounding aroma, Xu Xin could still feel that the aroma at this time was much stronger than at the entrance, and even began to be pungent, and a faint red mist began to float around.

Suddenly, a red light quietly lit up in front of him, making Xu Xin's heart skip a beat.

Taking a closer look, he found that the light source was Mimi walking in front, and he breathed a sigh of relief.

It was the blood-red patterns on Mimi's body that lit up slightly.

Is it because of the red mist around here?

The blood stripes on Ah Fu's body, which was lying on Mimi's back, did not light up. He turned back to look at Yin Wang and found that Yin Wang's body also had a faint red light.

It seems that intermediate mutant beasts are more sensitive to red mist, or in other words, they can use the red mist more efficiently. Even if the red mist is very thin now, it can still be used to strengthen their own strength.

However, this also sounded a wake-up call for him, making his spirit extremely tense in an instant.

His previous experience in the hilly resource area taught him that in areas with dense red mist, the protective effect of tree houses will become weaker, and there is a high probability that mutated organisms will exist.

In the cave, the spear was not easy to use. Xu Xin touched the blue-level iron sword on his waist, holding the crossbow with explosive arrows in his hand, followed Mimi, and walked forward slowly.

With.

Mimi also doesn't dare to walk fast. It can also detect unknown dangers ahead. When it steps on cat steps, its back feet will definitely step on the ground that has been stepped on by its front paws to ensure its own safety.

Just like this, after walking for a few minutes, it suddenly opened up before my eyes. One person and four animals walked into an underground space like a hall.

There was no other exit in the entire space, and it seemed that it was the end. There were no vines in this space, nor was there a beating "heart" surrounded by vines, which made Xu Xin a little disappointed.

They must have gone the wrong way. Xu Xin looked at her position on the map and saw that she was still some distance away from the tree house.

However, Xu Xin was not in a hurry to go back. He was attracted by the plants growing in the middle of this space.

They were three huge, very bright flowers, growing together in clusters. The petals of each flower were as big as lotus leaves, showing bright red like drops of blood, and in the center of the countless petals, there were clusters of yellow

The stamens look extremely beautiful.

Xu Xin was a little confused, how could there be such bright flowers in this dark underground?

He did not dare to approach easily. After all, in nature, the more beautiful the creatures, the more dangerous they were.

"Ugh!" Coco suddenly shouted.

...it means dangerous!

Xu Xin held an explosive crossbow and aimed it at the bright red flowers clustered together in front of him. If there was a problem, he would immediately pull the trigger. Silver King came to his side, Ah Fu flapped his wings and flew up, Mi

Mi arched her waist, ready to burst into pieces at any time and grab these flowers.

Suddenly, the stamen of one of the flowers trembled a few times, and a thick red mist suddenly sprayed out from the stamen.

Xu Xin almost pulled the trigger. Mimi's body also trembled. She obviously wanted to take action but held back.

The flowers did not spray out red mist all the time, but just sprayed for a while and then stopped. The red mist continued to spread in the air, and finally diluted into a light red mist.

A few meters away, Xu Xin smelled the familiar pungent smell.

His eyes gradually widened.

The red mist floating in the air was actually released by the flower in front of me!

The red mist spread around them, and Xu Xin couldn't help but inhale some of it. His mental power increased at this time, so he didn't feel any discomfort, but he just felt a bit unpleasant.

Beside him, the blood patterns on Silver King and Mimi glowed a brighter red than before, and even the blood patterns on Ah Fu's body glowed faintly.

The three beasts all showed some expressions of enjoyment. Their abilities were enhanced by the red mist.

Xu Xin suddenly had a bold idea.

After experiencing the red mist last night, Silver King and Mimi not only had no subsequent negative effects, they even directly upgraded today. This shows that this red mist is actually very beneficial to the mutated beasts.

resource!

The radiation stone that could enhance the strength of the mutant beasts had cracked, lost its effectiveness and turned into an ordinary stone. He needed other means to enhance the strength of the Silver King and them.

And now, this kind of flower that can produce red mist is right in front of him.

Then can he plant it? Build a small room, plant this kind of flower in it, and then let the Silver King and the others go in from time to time to steam the red mist like a sauna...

While he was thinking, the stamen of another flower moved and sprayed out a stream of red mist.

This situation reminded Xu Xin of the sunflower in a certain game, which would produce sunlight every once in a while, and this kind of flower would spray out a stream of red mist every once in a while.

Xu Xin took a tentative step forward.

"Hey!" Seeing Xu Xin walking forward, Keke became anxious, but he could clearly feel that there was danger in the flower's stamens! It waved its two little paws for a long time before Xu Xin understood what it meant.

"There is danger in the stamens..." Xu Xin narrowed her eyes.

The flower is not dangerous, the dangerous thing is the stamen. What is in the stamen of a flower?

Could it be...

Xu Xin held a crossbow in one hand and took out his sharp spear with the other hand. The spear was three meters long, and he gently poked the stamen of the nearest flower from three meters away.

"Buzz..." A sound of an insect flapping its wings came out from the stamens, giving Xu Xin instant goosebumps.

...There are indeed flying insects in the flower stamens!

And it is definitely a very aggressive insect, otherwise it would not have aroused Coco's alertness!

Fortunately, the insects did not fly out due to Xu Xin's touch, but there was no movement after making that sound.

"You guys, retreat, I'm going to bomb them." Xu Xin gave up the previous idea and solemnly gave the order to the four beasts.

If there are a lot of highly aggressive mosquitoes, even Silver King and Mimi may not be able to get away. Just like an elephant is powerless against a mouse that burrows into its trunk, small size can sometimes be an advantage.

It's better to nip the danger in the cradle.

Several flowers are clustered together, very close together, and one explosive crossbow bolt can blow them all up.

If one shot is not enough, use two.

Suddenly, the stamen of a flower trembled. Xu Xin relied on her super strength to clearly see dozens of flying insects with blood-red eyes and spikes on their mouths sticking out half of their bodies from the stamen.

Like a southern cockroach, its body is covered with thin blood-colored patterns.

They seemed to have seen Xu Xin and his party, they flapped their wings and were about to fly out immediately.

"Cover your ears!" Xu Xin warned the four beasts, and she no longer hesitated and directly pulled the trigger.

"boom!"

The explosive arrow exploded on the three flowers, and a huge explosion sounded in the enclosed space, making him temporarily deaf.

But his eyes were not damaged by the strong light of the explosion. Instead, he clearly captured the flying insects in the flowers that flapped their wings and tried to fly out at the moment of the explosion, but were still torn to pieces by the force of the explosion.

efficient!

Xu Xin didn't stop the movement of her hands, she wound up the string again and fired!

"Boom!" "Boom!"

Two more shots were fired, and the violent explosion shook the entire cave. Countless pieces of earth and gravel fell from the top of the cave, shaking Xu Xin's head and making him faint.

Fortunately, he still had the mental power boosts of oranges and strawberries, so his fainting only lasted for a moment, and he immediately regained his peak energy.

...I hope the entrance to the cave will not collapse due to the shock. Xu Xin thought, rubbing her ears that were temporarily deafened by the shock.

The power of these three explosive arrows was very powerful. Broken blood-red petals were blown up everywhere. Scorched tiger petals and insect corpses were spread all over the ground. None of the insects in the stamens of the three flowers were spared, and they were all killed.

Exploding.

"Explosive arrows are really useful." Xu Xin turned his head, and Coco on his shoulders covered his ears and locked his head. He flicked Coco's little head, "How about it, is it still dangerous now?"

Coco looked up blankly at the bombed plants. He stayed there for two seconds and shook his head: "Ugh."

The three beasts behind him also covered their ears and lay on the ground. Especially Ah Fu, whose hearing was very keen and couldn't bear the huge explosion. Xu Xin could even see a resentful look on its bat face.
