The last group of people entered the mine, and they were well prepared, not only headlamps, but also flashlights, and high-power lights for outdoor use!

In front of them, illuminated by the outdoor lights, they came to the entrance of the cave according to the traces left by the people in front of them.

Inside, there are many traces of people passing by, and at first they don't need to discern the direction at all, they can pass through one fork in the road after another.

Three hours later, when they reached a slightly larger area, Willis ordered everyone to take a short rest.

There is an underground river, where soldiers wash their faces by the light, and people take out food and sit on the rock wall to rest.

Willis sat resting on a jutting rock, holding Dr. Carr's notebook in his hand, and looked at the place where a slightly larger cross had been drawn, which, combined with the route before and after, should have marked the place of rest.

"What is this?" said suddenly, the soldier who was leaning against the rock wall, touching something from the ground.

When I took a photo of the place where there was light, the soldier turned out to be a pair of glasses in his hand.

"They've been here!" someone said immediately.

"That's right, this should be the glasses worn by the professor named Carl, I remember!"

Willis looked over, and the soldier immediately stood up and brought him his glasses.

Willis glanced at the black-rimmed glasses in his hand, yes, this should be the one that Professor Carl had brought.

This should be the place where Gio and Carl are finally separated.

"Search this place!" Willis shouted.

The soldiers immediately moved and began to search around, and after a while, someone in the innermost part shouted, "There are blood stains here!"

Willis hurried over there, and saw a soldier squatting on the edge of the mouth of a cave, which was not too big, round enough to allow one person to get into.

The blood was left underneath the hole.

Willis touched it with his hand, and the blood had congealed, and he rubbed a little bit of the dampness on the rock wall.

It seems that there are at least two or three days.

Forget it, it should be left shortly after Gio and Carl separated.

The soldier took a flashlight and shone inside, it was very deep, and there were bends, and it was not far away that there was nothing to be seen.

"Keep going!" Willis said, putting away his notebook and continuing his walk down the other side of the cave.

The first team, now deep into the last place where the exploration team stayed.

The reason why they are so sure is because they have found a lot of discarded equipment and equipment here.

"Rest in place!" said one of the soldiers.

Everyone found a place to sit down, and it took almost a day in a row, which made them a little tired, so they could only look at these things and leave them alone, and they had to eat something to replenish their strength before they could continue the next work.

A soldier put an outdoor lamp on a rock raised above him, and as soon as he slipped out, he sat down under the rock and pulled out the compressed biscuit in his arms.

These people were the first to come in, they were tired and sleepy, and some were already asleep on their sides.

The cave was unusually quiet, and suddenly there was a dripping sound, and a soldier closest to the underground river opened his eyes and looked at the underground river curiously.

The underground river was warm, and even if they slept on the ground here, they would not feel cold, but the soldier suddenly felt that something in the underground river seemed to be staring at him.

He reclined and stared at the underground river, when he suddenly saw two bright spots slowly approaching the surface of the water from the water.

A false alarm!

Thinking it was a fish, the soldier relaxed his body and put his hand in the water.

He touched something slippery, this fish is so big, if he can catch it, can he bake it and eat it?

A smile appeared on his lips, and suddenly, his hand did not move, and then, as if someone had grabbed him, he dragged him from the shore into the water.

The sound of falling water came with a "poof", which alarmed the others.

Almost everyone jumped up and grabbed the guns at hand.

"What sound?"

"What fell into the water?"

"Joseph, what about Joseph, which of you saw it?"

They noticed that one of their companions was missing and immediately looked at the underground river.

The sound just now, it was obvious that the sound of falling into the water was made by a companion?

"Did he fall in?" someone asked.

"Bring the lamp!" shouted the soldier, who was sitting on the edge of the rock, stood up at once, reached for the outdoor lamp overhead, and ran.

He took the lamp, pointed it at the underground river, and shone it back and forth.

"See?"

"No, nothing!"

Suddenly, a string of bubbles began to "gurgle" out of the underground river, and a helmet floated up.

Seeing this, the others all subconsciously stepped back, and after seeing clearly that it was a helmet, someone said, "It's Joseph's helmet!"

Someone standing next to him stretched out his gun and pulled his helmet to the shore, and reached for it.

He stood up with his helmet and turned to show the others, "It's Joseph's helmet, this place was knocked off the paint on the truck last time!" he told the group, and showed them the paint that had fallen off it, but the others looked at him motionless, looking behind him with horrified faces.

"What's wrong with you?" the soldier asked.

I saw one of his companions raise his hand tremblingly and point behind him, and the soldier turned back with a smile, "What are you kidding......

A huge black serpent, rising from the water, hung its head high and stared at them, and the soldier turned back as he spoke, and before the smile on his face could be put away, the serpent's mouth opened and pounced.

Half of the soldier's body was in the serpent's mouth, and his feet flicked a few times before he moved.

"Fire!" the captain suddenly shouted, and everyone reacted, grabbed their guns and opened fire on the serpent.

However, the bullets hit the scales of the giant snake's body, making a "clanging" sound, and sparks flew over.

The serpent was so angry by the bullet that it turned its head, shook off the soldier in its mouth, and pounced on several people on the shore.

For a moment, the sound of gunfire echoed far away in the cave, and Willis stopped and listened carefully, "Is it gunshot?" he asked.

Some of the soldiers in the back nodded, some shook their heads.

Presumably it was too far away, and they weren't sure if the faint sound they heard was a gunshot.

The second squad, which was closest to the first squad, could hear more clearly.

"It's gunshots!" someone said.

"It's Team One!"

"Speed up!"

The second squad's first reaction when they heard the gunshots was to speed up and try to meet up with the first squad as quickly as possible, without thinking about what exactly they were in and needed to shoot.

However, when the second team came to the place where the first team stayed from the cave on the other side, the sight in front of them made their scalps tingle.

They saw the first team, several of them lying on the ground covered in blood, and blood was everywhere, and the things they were carrying were discarded in a messy way.

"What's going on?" someone asked, followed by heavy breathing.

Ten people stood there and observed for a while, and then slowly walked in, and they first went to check on the people lying on the ground.

"Someone else is still alive!" a soldier suddenly turned around and shouted on the other side of the river, a bloody figure lying in front of him.

The men of the second squad hurriedly ran around the underground river.

"Corporal!" shouted someone, who did not recognize who the man really was, and the face was disfigured in a terrible way.

This person was still breathing, and he slowly opened half of his eyes in the constant calling, and after he saw the people around him clearly, he suddenly stretched out his hand and grabbed one of them, "Quick...... Let's go......"

"Corporal!" As soon as the man finished speaking, his head tilted and he lost his breath, and the blood on his face turned black visibly, and the person who was holding him quickly threw the person away.

"Poison!" The soldier he had captured looked at the blood on his hands, and there was a burst of heat on his skin, and he immediately ran to the edge of the underground river in a panic, put his hand in it and washed it vigorously.

After washing the blood off his hands, he breathed a sigh of relief and raised his hand in front of him to look at it carefully.

However, the small cut in his hand suddenly cracked open at some point, and blood flowed out, and then it turned black.

Immediately afterward, his entire palm slowly turned black, and continued to spread to his arm.

"I'm ......" he turned back to look at his companion with his dark palm.

His companions looked at him in horror and froze where they were.

The soldier remained motionless, his neck blackened, and his whole face turned black from the bottom to the top, as if someone had smeared paint from his chin upwards.

Even the whites of his eyes turned black.

The next moment, the soldier's eyes blinked, his body stiffened, and he fell into the underground river.

"Get out of here!" shouted the Captain Soldier, and everyone immediately ran to where they had come in.

However, at the exit, a huge eye was watching them, blocking them alive.

"Oh my God!" someone widened as the huge eye moved to the side, and the head of a giant serpent appeared at the entrance of the cave.

The sound of "da-da" gunshots came out again, mixed with the strange sound of "silk", and unsurprisingly reached the third squad behind.

The third team made the same decision as the second team, and ran inside at a faster pace.

"Die!" In the distance, the third team heard an angry roar, followed by a loud squeamish sound that caused the eardrums to ache, and someone was supposed to have pulled the grenade.

"Right ahead!"

The members of the third team endured the sharp pain in their eardrums and the constant tinnitus and ran forward more quickly.

At the entrance of a cave, they saw the sight inside that they would never forget.

A huge black snake, its body nimble through the cave, where rocks and underground water splashed everywhere.

There were also two soldiers desperately resisting, and the soldier who had just thrown the grenade took out another one, and just as he was about to open the safety and throw it out, he was swept by the giant serpent, and swept it to his body, and he immediately hit the rock above like a cannonball.

He spurted blood in the air, but he still managed to stay awake, the grenade in his hand did not let go, and in the process of falling, with a sinister smile on his face, he opened the safety and threw it at the giant snake.

Seeing this, the other man shot desperately at the serpent.

Seeing this, the third team also raised their guns and joined in.

Unexpectedly, they suddenly appeared, and were noticed by the giant snake, and after he let out a "silky" roar, he rushed into the underground river, and his huge body also took the soldier who had just landed to the side, and the grenade hit the snake and bounced back.

"Lie down!" the soldier commander immediately shouted when he saw this.

There was a loud "boom", a grenade went off, and the rocks and groundwater next to it splashed up again, injuring two people.

After a while, the third squad got up from their hiding places and was about to run to the last remaining soldier, when they heard the "bang" of the underground river and the serpent came out again.

"Run!" The soldier was badly wounded by the massive blast.

But he still raised his gun, aimed it at the giant snake, and with his last breath, shouted to the third team, "Run!"

The people of the third team also wanted to step forward to rescue him, and the guns in their hands also burst into flames.

However, then, the serpent swallowed the image of the badly wounded soldier in one gulp, forcing them to stop.

The tragic situation in front of them made them make a decision in an instant, turn around and flee out.
