Looking at the waterfall flowing down from a distance, Lan Feng's brows were tightly frowned.

After a silence, a faint voice came from Lan Feng's mouth: "Be careful, go up and take a look."

Upon hearing this, Zhuo Xiong nodded and walked out of the jungle with Lan Feng.

Walking to the huge pool under the waterfall, smelling the air around him, looking at the vortex slowly turning in the center of the pool, then Lan Feng bent down and tasted the pool water. After a moment, Lan Feng showed a faint smile on his face, nodded to the bear beside him, and a solemn voice came from his mouth: "It's almost here, it shouldn't be far away. I'll go down and see, you stay here, be careful."

After the words fell, Lan Feng placed his weapons and equipment on the shore, took a strong breath, then jumped directly into the pool and began to dive.

The bear looked at the disappearing Lan Feng who had sneaked into the pool, and looked at the surrounding scenery, his eyes full of vigilance.

Lan Feng, who jumped into the pool water, held his breath and dived hard. I don’t know how long it took, but the scene at the bottom of the pool appeared in his sight.

There was not much soil at the bottom of the pool, but covered with extremely hard boulders. In the center, there was a circular boulder with a radius of two meters, as if blocking something. Water pipes were placed on the edges of each boulder in the pool, which made Lan Feng smile slightly on his face. This should be the water supply system of the underground experimental laboratory.

After careful observation, Lan Feng began to dive. He had already understood the situation here almost.

"Crazy..."

When Lan Feng emerged from the pool, a hint of joy appeared on Zhu Xiong's face: "Brother Feng, have you noticed anything?"

"Go down and take a closer look. The water supply system of the underground experimental institute should be below. However, those water supply power systems are blocked by a huge rock and cannot move. They should not be able to enter below." Lan Feng was silent for a moment and continued to speak: "However, the wild wolf just now disappeared into the waterfall. I think there should be an exit from the experimental institute, otherwise the wild wolf would not be able to come out. After all, according to various circumstances, the wild wolf was raised."

Upon hearing this, Zhuoxiong nodded in agreement: "Then let's go over and take a look."

"good!"

Lan Feng nodded, and raised his weapon and equipment with one hand above his head, then swam under the waterfall and began to climb up.

"Be careful." Lan Feng stood inside the waterfall and said to the bear behind him.

The bear nodded, and the two of them looked at the wolf's footprints on the ground and walked carefully.

It was not big, but it was still very small. The two of them walked in less than a minute and came to an end, and a stone wall appeared in their sight.

There is a big hole at the bottom of the stone wall for people to drill into, and the wolf's footprints disappear here.

Lan Feng made a gesture of silence, then lay down and put his ear close to the ground and listened carefully, then carefully put his head close to the big hole and looked inside.

A moment later, a solemn voice came from Lan Feng's mouth: "The wild wolf should have entered from here. You can hear the sharpness and biting sounds from inside, and you can vaguely see a vague shadow below the entrance of the cave. It should be a group of wild wolf locked in it."

"This hole was deliberately made by the people inside. I believe that ordinary wolves can't come out of the hole at all, unless they already have such a little mutant gene.

Hearing Lan Feng's words, Zhuo Xiong was slightly stunned, with a strong solemn look on his face, as if there were a group of wild wolves inside, that would be troublesome.

Lan Feng made a gesture and the two quietly pushed them out.

"What do you think?" Lan Feng stood by the pool and turned to look at the pond who was thinking.

"If they had deliberately shot the hole, there were holes that appeared in other places where other animals were imprisoned. We can try to find it." After a moment of silence, the bear slowly spoke.

"I agree with your idea." Lan Feng nodded: "Then let's look for it separately and gather here in an hour and a half."

"good!"

Zhuoxiong nodded and acted separately with Lan Feng.

An hour and a half later, Lan Feng and Zhu Xiong appeared by the pool at the same time. Both of them smiled bitterly and shook their heads with a little disappointment. It was obvious that there was no other gain.

Of course, if you insist on harvesting, the bear brought back a little wild boar.

It was already noon after this time. The bear skillfully dissected the little wild boar and washed it. Then he set up a fire on the side and roasted it. Lan Feng smiled and threw it to the bear a bottle of seasoning.

Although there was no harvest, I still had to eat it, because Lan Feng and Bao Xiong knew that there was still a tough battle to fight next.

Since there is no other entrance to enter, you can only go down from the ground of the wolf cave.

After replenishing the energy, Lan Feng and Zhuo Xiong moved on, looked at each other a little, and then began to customize a simple combat plan.

Looking at the wild boar that deliberately left half of it, Lan Feng smiled slightly on his face, and then he heard from his mouth with a solemn voice: "According to the Lone Wolf, there is a dangerous person named Tieyu, we should try to be careful when we go in and figure out the situation."

Upon hearing this, Zhuoxiong nodded and then followed Lan Feng to the entrance of the cave behind the waterfall again.

"I'll go down first in a while."

Lan Feng turned his head and said to Zhu Xiong.

Then he threw the wild boar meat left by the bear into the hole directly.

"Aoah..."

Suddenly, a commotion came from the hole, followed by a biting sound.

"Swish!"

Lan Feng's body jumped directly into the hole.

Below the cave is a huge cage, with more than twenty ferocious wild wolves covered in it.

The moment Lan Feng threw the wild boar meat into the cage through the hole, more than 20 wild wolves were biting and fighting for the wild boar meat like cats. Lan Feng's body took advantage of this opportunity to fall quietly into the cage.

"Swish swish swish swish..."

Dozens of silver needles quietly sank into the body of the wild wolf who was struggling to eat, instantly cutting off their voices, but some of the wild wolves still noticed the existence of Lan Feng, exposed their sharp fangs, and bit them at him.

"Swish!"

Lan Feng's palm was as fast as lightning and took a handful of silver from the bracelet and threw it out in front. The silver needle was extremely fast and could not even see the shadow. It instantly penetrated into the bodies of several wild wolves, cutting off their vitality.

The remaining wild wolves roared sharply and bit Lan Feng.

"Swish!"

At this moment, the violent bear jumped down from the entrance of the cave, swung its huge and hard fists directly onto the body of the wild wolf, shaking them away.

Then the violent bear was like a black bear running out, and the sword appeared in his hand, instantly ending the lives of the wild wolves.

Only the wild wolf that Lan Feng and the others first chased for did not die, and a low roar was heard in their mouths. This guy's life is so tough.

"Swish!"

It was about to launch a surprise attack on the violent bear, but Lan Feng's body flashed and appeared immediately beside the wild wolf. The sharp saber pierced its head directly.

More than 20 wild wolves were quickly resolved by the two of them.

"bite!"

Looking at the locked iron cage door, Zhuo Xiong shook his body, cleverly opened the iron cage door with the sharp saber in his hand, and then flashed out with Lan Feng.

Walking out of the dark cage, a huge hall appeared in the sight of the two of them. There were locked iron cages everywhere, and all kinds of animals were imprisoned, including wild leopards, bobcats, wild wolves, giant pythons, rattlesnakes, wild dogs, owls and even humans. They looked full of blood and horror, and the roars of various animals were constantly, and some had already begun to show signs of mutation.

Looking at this scene, Lan Feng and Zhuo Xiong frowned tightly, their faces looked extremely ugly and gloomy. No wonder they felt that this place was too quiet along the way. It turned out that all the animals were caught here and used as experimental items for research.

Lan Feng and Bao Xiong looked at each other and walked to the two humans who were locked in the cage as experimental subjects. They found that they had no movement at all and had no hope of life. However, through their hideous faces before their death, it was vaguely seen that they were still young and would never be over twenty years old.

After walking a distance into the hall, Lan Feng's face became even more gloomy. He had seen more than ten young corpses, no more than twenty years old, and even a few female corpses.

Before they died, they held a school sign tightly, their eyes full of fear and reluctance towards death.

These girls should still be college students.

After walking around the hall, Lan Feng and Zhuo Xiong's faces became increasingly ugly. They counted and found that more than 30 young humans, twenty-three men and nine women died.

The only living human being is a pretty and well-behaved woman. She looks seventeen or eighteen years old, her short black hair is already dirty, her school uniform of Suhai University has been torn to pieces, her legs are covered with blood, and her beautiful cheeks are no longer vital and vitality. Her eyes have long lost their due glory and become empty and unconscious. She has opened her mouth full of blood and chewed her fingers. Seeing Lan Feng and Zhu Xiong coming, she opened her mouth and let out a low roar, and she has long lost consciousness...

Looking at these scenes, a cold feeling spread out from Lan Feng's mouth, with unconcealed murderous intent in his eyes, and a cold voice came from his mouth: "Kill them all, no one left. These damn scumbags!"

At the same time, Lan Feng took out his cell phone, took pictures of the scene in the surrounding hall, and sent a MMS to the nine-digit number.
