The so-called genes, as long as they are creatures within the same race, should have a genetic similarity of more than 99.9 percent, and if they are related by blood, the genetic similarity is higher, in which similar genes constitute various characteristics of human beings, such as body, consciousness, intelligence, etc., and the difference of 0.00 percent constitutes the difference in each person's appearance, xìng personality, blood type, and so on.

Of course, most of the genes have never been used by humans since birth, and these genes are remnants of previous human evolution, from single-celled organisms, multicellular organisms, amphibians, fish, ...... In this way, all the way to human beings, these ancient genes are mostly left, but it does not mean that these eliminated genes are bad genes, and sometimes the good things are likely to be the fastest eliminated things.

When a person is able to control his genes, these genetic faults will be awakened by them, the power hidden in them will be awakened, and the savage killing aura hidden in these genes will also be awakened.

Zheng Zha can't remember when he had this feeling, it seems that in the repeated bloody battles of the Galaxy Clan, he kept unlocking the genetic locks, kept simulating other people's thinking patterns, and kept struggling on the verge of death, in that case, he already had a vague feeling, and when he really woke up, it was back in Resident Evil, when he had killing intent to kill everyone in the research institute, he was full of killing intent and anger, plus when he fought a large number of gigantic creepers later, at that moment, He lost consciousness...... When Zheng Zhe came back to his senses, more than half of the creepers had been cut to pieces by him, and he himself was almost unscathed, and in that battle, he finally knew that he had once again made a breakthrough...... The fourth order of the gene lock is unlocked, and the zhì gene is controlled.

According to the experience he gained in that battle, the fourth order of this gene lock is divided into three stages, which can be distinguished by primary, intermediate, and advanced, and the primary is his current state, and he can cultivate his ** in the most optimized way, and awaken the ancient evolutionary genes that human beings have never used in their lives, so that he can adjust the body element that is most suitable for him.

It can be said that by this step, he was no longer so eager to exchange the high-level blood genes from the "main god", because he could already optimize his genes on his own and maximize his potential.

For example, he can change the gene pattern according to the amount of energy he has, and use his attack method that is more suitable for "explosion" and "destruction", and exert his power to 100% Cheng Dù, no wonder it is said that only by unlocking the fourth order of the gene lock can he exert 100% of the power of his skill.

Untie the fourth order of the gene lock, the primary state is to wake up the useless genes sleeping in the body, adjust the state of oneself to the optimization, all skills can reproduce 100% power (Zheng Zha's state), the intermediate state is to evolve and change one's own genes, and transform oneself into a stronger state beyond optimization, any skill can use 100% of the power, and it can create zào skills according to the information provided by genes, advanced state, and control the energy in the body from the gene level, It is only one step away from unlocking the fifth order of the genetic lock...... Zheng Zhe moved his left shoulder slightly, and let a strong orc stab the dragon spear in a thousand shots, and then his left shoulder hit outward, the dragon spear was completely bent, and then flew out a few meters away and swept down more than ten strong orcs in a row, these strong orcs broke their arms and legs when they touched the dragon spear, and the force of this shoulder hit was so terrifying.

Then Zheng Zhe stretched out one hand and grabbed the strong orc who stabbed him just now at a speed that was difficult to see with the naked eye, and then his hands were linked, and the strong orc was torn to pieces by him.

(The twenty-seven strong orcs on the left put up their shields and prepare to attack, and their left hand can be broken by using seventy percent of the "explosive" state power gathering...... (The two orc captains on the right are aiming with burst arrows, and they need to use the "Instant Destruction" status to dodge or take down...... (The "explosive" state consumes seven percent more energy, weakening the control of the third pair of genes and increasing the output of the seventh pair of strength genes...... (Slightly slower reaction speed, strengthens the eighth pair of genes...... These are all things in Zheng Zhe's mind, but the people on the city wall are dumbfounded, just below the battlefield, a killing machine keeps breaking into the strong orc battle array, it seems that the speed is not fast, but all creatures within five meters of him will be torn apart by him in the next second, Zheng Zha actually threw the tiger knife on the ground, his mouth kept letting out a beast-like roar, every time he killed the enemy was tearing hard, so every strong orc killed by him was extremely miserable, The horrific gore even caused some of the conscripted civilians on the city walls to vomit.

This is the reason why Zheng Zha concealed that he unlocked the fourth order of the gene lock, because he could not control this powerful and incomparable power, the fourth order of unlocking the gene lock was almost completely different from the first three orders, and this stage really came into contact with the origin of life, and the fourth order in the primary state, of course, awakened the ancient traces that were sleeping in the genes, but it also awakened the rage and bloodlust that was only for survival when the pure life was a pure life, there was no reason, there was no reason, Zheng Zha now just wanted to kill the one in front of him, the strong orc, the wizard, Humans on the walls, and even ...... A member of the reincarnation team of the Middle-earth team, with his current strength, he is not afraid of anyone!

However, the strong orc army is the closest to him, so it is these strong orcs that he attacks first, and several strong orcs are torn apart by him every second, whether it is the head, chest, or belly, every move is absolutely certain death, Zheng Zha sneered and licked the blood from his mouth, after he walked out of the broken wall, he had gone deep into the strong orc battle formation more than ten meters away, and the strong orcs who were still indomitable at the beginning were retreating again and again at the moment, not because they were afraid, but they fully understood, Why can't this man in front of him be killed, obviously he used his bow and arrows to strike, but those bows and arrows avoided him as if they had eyes, obviously stabbed him, but in an instant, he found that the stab was somewhere else, and as soon as he got close to him, it naturally became several sections, such a terrifying situation made the strong orcs can only retreat.

(Not enough, not enough, you have to kill many, many creatures, you have to keep killing!) "Whew! ”

Zheng Zha suddenly raised his head to the sky and howled loudly, he jumped towards the retreating army of the strong orcs, this jump was seven or eight meters high, and then when he fell, he pressed heavily on the bodies of several strong orcs, and the bodies of these strong orcs were instantly crushed into flesh, at this moment his reaction speed was faster than the previous state of "ruined miè", and when all the strong orcs came to their senses, he had already dragged a strong orc to tear in the air, and with a bang, blood and internal organs drenched him...... (Kill, kill, kill...... Kill all the creatures! Will...... The descendants of the saints are killed! Extinct humanity! Zheng Zha bit the head of a strong orc in front of him, he naturally had such an idea in his mind, when he bit the head like an apple, the last paragraph made him suddenly startled in his heart, and then he recovered from the fourth order of unlocking the gene lock, and the place was full of shapeless broken corpses everywhere in front of him, and in front of him was the defeated and fleeing strong orc army, I don't know when, he had left the castle a hundred meters away, Maybe he subconsciously left in the opposite direction of the castle, after all, with his state and strength at the time, if he had been in the castle, maybe when he came back to his senses, it would have been all shattered to the ground...... Zheng Zhe turned around and walked silently towards the castle, his hair, face, mouth, clothes, and body were full of minced meat, internal organs, blood clots, filth, and so on, making him look more terrifying than a monster, so when he turned around and walked towards the castle, some of the archers on the city wall roared in fear, and half of them even held bows at him, because Zheng Zhe's appearance was so terrifying, just like the description of the dark king Sauron in the book, An invincible inhuman force.

Zheng Zha didn't care about these archers, he silently walked in from the broken point of the city wall, and sure enough, he saw Zhao Yingkong and Cheng Xiao not far from there, at this moment Chu Xuan was already held in his arms by Cheng Xiao, this young man with glasses with an ordinary appearance, at this moment, he still looked indifferent, and he couldn't see the pain of death at all.

"Yes, too...... He didn't feel pain, unless he unlocked the fourth order of the genetic lock to get back the one that a human should have, but ......"

Zheng Zha walked to the two of them, and he didn't care about his flesh and blood, but asked silently, "Are you really dead?" ”

Cheng Xiao nodded and said: "Indeed, you touch his heart yourself, his heart has been shattered, and the blood has not flowed, and after more than two hours, his brain has almost died, he ...... It's really dead, but it's very strange, the liquid made of the leaves before can still be poured down, is it possible that the leaves will disappear even if they are put in the mouth of a dead person? ”

"More than two hours?" Zheng Zha turned his head strangely, he looked at the battlefield outside the broken wall, there were at least thousands or even more broken corpses on the ground, it turned out that he had been fighting for more than two hours after unlocking the fourth order of the genetic lock, no wonder those strong orcs retreated...... "It's really unthinkable, a man like you would actually die like this, I originally thought that you would be wiped out by the 'main god' because of his calculations, or directly drag the 'main god' to die together...... You bastard, you haven't even figured out the feeling, and you just died painlessly? ”

Zheng Zhe just sat directly on the ground, he kept muttering with his head down, as if something wet had slipped off his face, and after saying this, he had fainted unconsciously...... The battle just now had drained all his energy, and he was still able to walk, just because he wanted to see this brother for the last time.

(Farewell, Chu Xuan, go all the way!) Before Zheng Zhe fainted, these were the last words in his heart......
