Kukas finally agreed. Then the female doctor led him to the pit to watch.

I saw a big man in the pit with the shape of kukas walking uneasily at the bottom of the pit. He looked up from time to time, and then continued to walk in circles at the bottom of the pit.

"He used to be a miner?" looking at the muscles of the other party and then at his own, kukas shook his head. He did not expect that doctors would make a thin miner look like this in a short time.

"Yes, all you have to do is try your best to kill him. We told him that as long as he can kill you, he can get free and leave the ghost place." the female doctor explained softly.

"Bare handed?"

"He hasn\'t received any weapon training. You\'ve taken advantage of him with your bare hands. Well, I heard that you\'re honing your killing skills now, but you\'ve never had a real experiment with your opponent, so you\'d better take this opportunity!" an old doctor said excitedly.

"Let me down." kukas took off his clothes, leaving only a pair of cowhide shorts.

Seeing that he was ready, the doctors immediately opened the mechanism on the cover and revealed a big hole. Without the aid of any tools, kukas jumped down.

A deep pit more than three meters high. When kukas was still in midair, the miners at the bottom of the pit roared and were ready to attack. The miner moved quickly on the ground and then hit kukas hard where he landed.

As he fell, kukas didn\'t dodge. His hands crossed into a cross, and then waved hard to the outside.

The two thick arms with an evil wind beat the miners hard. There was a loud bang, and two huge figures retreated and flew backwards at the same time.

Kukas only felt his two arms beating on the hard obsidian. He only felt pain and numbness in his arms, and stabbing pain came from the whole bone.

The body slammed heavily against the wall of the pit, roared, kicked on the ground with both feet, and rushed towards the miner who had not yet stood firm like a strong wind. This time he crossed his hands in an oblique cross and went to beat the miner again. The miner screamed, his hands wide open, and grabbed kukas by the shoulder.

"Go away!" kukas poured all his strength into his arms. He believed that even if a huge stone was in front of him, he could break it.

However, things didn\'t develop as he thought. He beat his arms on the miner\'s chest. He just listened to the snort. He forcibly pulled out two blood marks from the miner\'s chest, turned the flesh and blood, and exposed the thick white bones.

At the same time, the miner\'s hands were also on kukas\'s shoulder, which should be two flesh and blood.

Pressing down the pain, kukas turned to the miner\'s left, and the huge fist round hit the miner\'s neck. One punch down, only the miner screamed in pain, but there was no end of broken bones and tendons as kukas imagined.

Fighting, they are like the enemy and us on the battlefield. The miner didn\'t master the killing skills. He just fought with his own strength; Kukas mastered the killing skills. He kept experimenting with his skills on the strong miner, so that he didn\'t have to worry about each other\'s death.

With the passage of time, kukas tried to avoid the attack of the other party, because the miner\'s strength was so great that it was almost equal to him, and he didn\'t know how the doctors did it. He made the miner\'s bones extremely hard. When he grabbed him with ten fingers, he could take a piece of flesh and blood every time.

Five fingers are like a knife, which can only leave a blood mark on the miner\'s back; Ten fingers become claws, and one claw can only tear a small piece of muscle; His legs are like axes, but he can\'t hear the sound of broken bones.

A series of killing techniques were used by kukas again and again, from exhausting all his strength at the beginning to maintaining a certain strength at the end. Gradually, he became more and more familiar with the killing skills he had just learned, and the skills used under the same strength were more and more powerful.

In this way, the miner couldn\'t hold on. After fighting for less than half of Zhu Xiang\'s time, kukas used a battle axe in the knight\'s fighting skills to kill him. After a leg was severely drawn on the miner\'s back, he hit him to the ground and couldn\'t stand up again.

Big mouthfuls of blood gushed out of the miner\'s mouth, but there were no visceral fragments, and his body fluctuated. The thick breathing sound was so obvious in the quiet pit. He struggled a few times, but he had no strength to get up and fight with kukas.

"Don\'t kill him, wait until he is cured, and then continue to be your partner." the doctor reminded kukas to stop in time. Kukas didn\'t intend to kill the miner\'s test object. He planned to leave the other party as a prop for cultivating his killing skills.

After climbing out of the hole along the rope, kukas found that there were seven or eight wounds on his body, and some meat pieces were torn off by the other party. Fortunately, doctors have special drugs. After applying those drugs, the lost meat will grow in a short time.

"How do you feel? What\'s the power of this test article?" an old doctor came to ask kukas quickly regardless of the female doctor\'s application of ointment.

"Haven\'t you recorded it? Can\'t you even see these?" kukas gasped. He felt that this fight was more tired than when he killed a magic on the battlefield. After all, the area of the pit is too small. There is not much place to dodge. We can only fight with the miner with similar strength. This is an important reason for his fatigue.

"The record belongs to the record, and what you explain belongs to you." the doctor shook his head and explained, "the more detailed the test data, the better. I think you know these."

"The strength is very strong, the bones are very hard, the hardness of the muscles is stronger than me, and the anti Strike ability of the internal organs is more than ten times that of me." kukas recalled a little and said.

"I used several killing skills, all of which were to attack the internal organs, but I hit him three times with all my strength, but his internal organs didn\'t suffer any damage. If these attacks all fell on me three times, if I didn\'t fight and resist, I would definitely die because of the rupture of the internal organs." Kukas frowned slightly and said his discovery in detail.
