Ke Lan remembered that he had seen a post on a forum, in which a group of bored guys gathered together to discuss how much force was needed to tear a person's head off his neck. At first, only five or six people were discussing this topic, but later it became more and more popular for some reason, and even some professionals got involved in this topic...

Although Ke Lan didn't pay much attention to the specific content of the discussion, he still remembers the final conclusion: without the aid of any tools, the force required to separate the head and neck longitudinally is approximately between 150 kilograms and 200 kilograms.

The force of a punch from a top human boxer who has not undergone body modification is approximately 500 to 800 kilograms. Although the two have different ways of exerting force, it is at least certain that this force is still within the scope of human capabilities and is not too exaggerated.

"Although this attack method is bloody and terrifying, the force required is not exaggerated." Ke Lan commented, "With the help of the power armor, we can easily pull off a human head."

Not to mention tearing a head off, with the power of the crystal engine, Ke Lan could even grab a person's shoulders and tear him in half... Compared to machines, the human body is still too fragile.

"No..." Ivan's voice trembled, "Ke Lan, look at this."

His fingertips were pinching a piece of metal debris less than one square centimeter in size. The metal debris was covered in blood and pus. It was obvious that it was dug out from the rotten head.

"This, this is... the neck locking ring of the TR03 power armor!" After studying it for two seconds, Layton recognized the origin of the piece of metal, but at the same time, his face turned pale in an instant, "Is this thing... embedded in this guy's neck?"

Ivan nodded.

"Moreover...there are no signs of acid corrosion on the fragments..."

Everyone present felt their hearts sink suddenly... This piece of metal fragment appeared in the flesh and blood, which meant that the dead man had his head ripped off by those things while wearing power armor...

"Layton, can your mechanical arm remove the fixed power armor helmet from the torso?" Ke Lan couldn't help but ask.

"If we use a welding torch, it will take about three to five minutes to cut the helmet off... If we rely solely on mechanical power, it will be difficult..." Layton shook his head.

"It seems that the things in the mines are far more powerful than your mechanical prosthesis." Ke Lan suddenly felt his throat was dry and he wanted to drink water.

"Hmm..." Layton nodded with a serious face.

Ke Lan was silent for a few seconds, and after taking two deep breaths, he spoke, "Ivan, collect the genetic samples of the victims. We will rest here for ten minutes and check our equipment one last time. After ten minutes, we will continue to move forward."

This was bad news, but they all knew in their hearts that it was not the worst news.

…

Ten minutes later.

All the obstacles blocking the mine tunnel have been cleared, and in addition to the rotten head, they also found two bloody intestines and a finger that was completely severed in the pile of debris. Ke Lan also asked Ivan to collect genetic samples one by one.

"Ke Lan, to be honest, I always feel that..." Lao Gou stopped talking halfway and closed his mouth with a serious look on his face.

"I know what you're worried about." Since both of them were wearing heavy power armor, Ke Lan didn't pat Lao Gou's shoulder, but gently touched him with his elbow. "Don't be so nervous. You look like a rookie on his first mission."

"I'm not nervous, I just, just...ah, damn it! I won't say it anymore, it will bring bad luck if I say it, just treat it as if I just farted!"

"You mean to say you have a bad feeling, right?"

"Oh, damn it, I've already told you that I don't want to bring bad luck by saying it out loud, why don't you just hold yourself back?" The old dog cursed angrily, "Have you been possessed by that fool Layton?"

"This is all superstition. I believe in science," Ke Lan replied.

"What a bullshit science! Pah!" The old dog patted his chest armor. "The alloy power armor, the crystallization of human cutting-edge technology, was still torn apart by those monsters. Science? Science is bullshit in this damn place!"

"It's just that the armor isn't thick enough. If you put a battleship here, do you think those things can tear through the battleship's armor?"

"Don't forget where we are now..." The old dog stomped his hands on the ground in dissatisfaction. "If this big guy is still alive, the battleship will be nothing but a small shrimp in front of it."

"This... I really can't refute this." Ke Lan curled the corners of his mouth and announced his defeat.

The existence of Leviathan itself is a paradox, and the current practice of mankind is to "turn a blind eye" to it - when conducting biological research, this type of "primitive species" is excluded by default... Otherwise, many theories that were once regarded as classics will become fallacies, and the scientific edifice built over tens of millions of years will collapse in an instant.

Everyone knows that this is just deceiving oneself, but people have no choice but to cover their eyes - those truths will only bring disaster to the human world at this stage.

"Forget it, since we are here, it is a blessing, not a disaster. If it is a disaster, we can't avoid it. Let's go. If we really encounter some monsters, we will kill them first."

"The unknown is the source of fear. When we really face those things, maybe we won't be so scared anymore." Ivan said softly. He subconsciously glanced at his prosthetic limb. "I've died once. There's nothing to be afraid of."

"So you must come back alive this time - ah!" Leighton had just said half of his sentence when he was hit hard in the lower abdomen by the old dog's elbow, and immediately let out a cry of pain.

"Just shut up the fuck. How can you stick a flag on your companion like this?"

"Then don't do it. You are wearing armor now." Leighton said miserably.

"When you had clumsy hands and feet before, did you remember that you had prosthetic limbs? How dare you say that to me?" The old dog rolled his eyes at him immediately.

"You old thing—"

"Okay, how about you two go outside the mine and have a fight, and then we can continue the mission after the winner is decided?" Ke Lan advised. However, he felt that after these two people made such a fuss, the atmosphere in the team was not as tense as before.

"Okay, I won't bother with idiots." The old dog immediately "generously" expressed his willingness to give in, while Layton said nothing and secretly gave him a middle finger behind his back.

"Okay, are you ready?" Ke Lan pulled the bolt hard, "Let's go. The target is 300 meters outside the mining area, the territory of unknown creatures. If you find those things scary, just smash them all -"
