Nearly half an hour later, Yu Xun'er finally shouted out, and Lin Tianhua and Zhan Jiu also let out an intermittent snort, but for the sake of the man's dignity and the gamble, the two of them still endured it and didn't shout.

If a cultivator with good talent wants to cultivate from a first-order cultivator to the ninth-order level, it generally takes about fifty years, and a very good qualification takes about thirty years, and some rare cultivation geniuses may be able to reach a ninth-order martial artist at the age of thirty, but no matter how talented they are, their strength must be increased step by step, but the scientific and technological civilization of the Theron civilization has found a unique way, enhancing people's strength and lifespan by strengthening human gene cells, and in a short period of time, an ordinary person can become a high-level martial artist-like existence. But this enhanced strength naturally does not appear out of thin air, but through the transformation of energy, it is integrated into the human body while being genetically changed, and the pain in this can be imagined.

When the Theron civilization was first in the stage of genetic enhancement experiments, the mortality rate was very high, and it was precisely because of the death caused by the great pain of the genetic change that ordinary anesthesia was useless, even general nerve anesthesia had no effect.

After thousands of years of experiments, the Theron civilization has finally mastered a technology, which is called absolute sleep, which requires more than ten kinds of special plants to make people's consciousness enter absolute sleep without affecting the brain's thinking. Absolute Sleep may sound like sleep, but Absolute Sleep is definitely a state-of-the-art technology.

As we all know, we humans all want to sleep, and sleep is just a kind of shallow sleep, in order to let the brain rest, and the coma caused by some trauma and other external factors is called dormancy. There are three types of dormancy: mild, moderate and severe, and after dormancy comes deep sleep, which actually has a more appropriate word, that is, vegetative person.

There are also three types of sleep, which are mild sleep, moderate sleep, and severe sleep, which are mainly divided according to the degree of perception of the outside world by the sleeper, and after these three are absolute sleep, and only absolute sleep can completely eliminate the pain caused by genetic reinforcement.

Due to the rush of time, it was difficult to get together the materials needed to make people fall into absolute sleep, so the light did not prepare the 'medicine', so that Yuchen and the others could only rely on their own perseverance to bear the pain caused by the transformation, and if the people who were not strong in willpower or physical fitness were not strong, they would definitely die because of the severe pain. Of course, Yu Chen couldn't think of this, if Yu Chen knew that there would be such a danger, he wouldn't let his partners directly carry out genetic enhancement like this.

Guang didn't tell Yuchen and the others about the danger of strengthening genes before they entered absolute sleep, not that Guang deliberately concealed it, after all, Guang was just a set of programs, no matter how smart it was, it was just a set of codes, Yuchen and the others didn't ask any questions, it naturally wouldn't take the initiative to say it, after all, its amount of information was too big and too big, if it took the initiative to say it to the outside, then Yuchen and the others couldn't listen to it for a million years.

Yu Chen listened to the painful moans of his companions outside, and a trace of unhappiness gradually rose in his heart, although he could bear it, but he was different, not to mention that he was a soul core master who had suffered more intense pain, just because his body that had not been improved by the divine fruit since he was a child was not comparable to others.

Chu 'Yu' and a few other 'girl' children kept moaning in pain, while Lin Tianhua and Zhan Jiu also began to let out a low roar, which showed how strong the pain they were suffering at this time.

"You must hold on!" Yu Chen said as he looked at the gene chamber in front of him, his eyes flushed. Time continued, until it was nearly an hour, only with a tick, the 'door' of the third gene room flashed green, and when the 'door' slowly opened, I saw Lin Tianhua's face 'pale' and sweaty walked out. Yu Chen hurriedly ran over and helped him up, Yu Chen didn't ask much, because Yu Chen knew that Lin Tianhua was already exhausted at this time.

Helping Lin Tianhua to a clearing and letting him sit down cross-legged, Yu Chen said, "Don't speak, recover first!" Lin Tianhua nodded, although he experienced the hellish pain just now, but at this time, Lin Tianhua's eyes did not have a trace of fear, but a trace of excitement flashed. Lin Tianhua clearly felt that although he was exhausted by the pain just now, he couldn't exert any strength, but he knew that he was definitely not exhausted in the real sense at this time, he could feel that his body was full of strength at this time, and this power did not need to be mobilized as before, but was directly integrated into the bloodline, that is to say, even if he did not mobilize his fighting qi at this time, he would be several times stronger than his previous peak state.

Lin Tianhua was not injured, but because of the pain that tortured the nerves enough, he sat outside at this time, and in just a few minutes, his mentality was adjusted, and naturally there was no big problem.

"How is it?" Yu Chen couldn't help but ask when he saw Lin Tianhua coming over. Lin Tianhua punched the air, a trace of excitement flashed on his face, and said: "I feel that the strength in my body has increased several times, if I use the Dou Qi, the combat power should be about thirty times stronger than the previous peak level! But I'm still at the level of the ninth order, the peak of the ninth order!"

Yuchen nodded after listening to what Lin Tianhua said, and was about to speak, only to hear the ticking sound coming again, this time it was the fourth gene room.

"'I'll give it to you'!" Yu Chen said, the No. 4 gene room is where Dong Xuan is located, and Yu Chen naturally wants to show Lin Tianhua. As the metal 'door' of the No. 4 gene chamber opened, a figure poured out of it, and Lin Tianhua exclaimed and held it in his arms. Seeing Dong Xuan faint to death, Yuchen became more and more worried.

After a few more minutes, the 'door' of the No. 2 gene room finally opened, and Zikong Bing, whose face was pale was revealed, at this time, Zikong Bing's mind had reached the point of 'confusion', and he might faint at any time, so it was naturally impossible to leave the gene room by himself, Yu Chen rushed over and gently hugged it out.

"How is 'Jade'er?'" Zikong Bing was carried out of the gene room by Yu Chen, and took a few deep breaths before regaining a trace of his ability to speak, Zikong Bing was naturally very worried about Chu 'Yu', she couldn't believe that Chu 'Yu', who was weak, could withstand the extreme pain that was a hundred times more painful than Ling Chi.

"'Jade' is not over yet, you should recover first, don't worry!' 'Jade' will definitely be fine!" At this time, Yuchen's heart was already 'confused', although he was more worried about Chu 'Yu', but he could only comfort him like this.
