"Warning: Abnormal biological energy is detected in the host gene chain, and unstable fluctuations occur."

"Warning: The host gene chain has entered an abnormal state due to instability and fluctuation, please inject the bioenergetic repair gene chain."

"The degree of gene chain damage is 86%!"

As the cold warning sound of the system sounded, Chu Xun also felt that the genes in his body that had been calmed down with great difficulty began to re-disorder and become violent, and at the same time, bursts of tearing pain continued to rise from all over his body, and spread like a tide.

"Damn, the damage is still so high!" Although he knew very well in his heart that it was impossible to completely repair his genetic damage with just a few hundred crystal nuclei at the beginning, Chu Xun still didn't expect that his genetic damage had reached such a terrible level.

Fortunately, with enough bioenergy, these injuries can be controlled and recovered.

Thinking of this, Chu Xun didn't care about anything else, and directly held those second-order red crystals in his hand and began to absorb them.

The reason why the value of second-order red crystal is a thousand times better than that of standard crystal nuclei is not only because of the majestic energy contained in it, but also because this high-order crystal nucleus that has been deeply transformed by biotechnology is easier to be absorbed and utilized by humans, and it brings fewer side effects to humans.

To use a simple analogy, the standard crystal nucleus is like stagnant water in a mud pit, although it can also replenish water (life energy), but at the same time, it will also bring some harmful substances (virus energy) into the human body. While these harmful substances are not fatal to people, they can affect how quickly people absorb water.

The second-order red crystal, which has undergone deep processing, is different, it has already undergone a transformation process in the body of a third-order dangerous organism, becoming more pure, and then undergoing a secondary processing of biotechnology. Compared with the standard crystal nucleus equivalent to sewage, second-order red crystal is more like filtered pure water, which is not only easier to absorb by the human body, but also brings fewer harmful substances.

Therefore, almost at the moment when Chu Xun began to absorb it, five walnut-sized second-order red crystals were instantly shattered, and then turned into a brilliant red light and integrated into Chu Xun's body. Subsequently, a little red light also appeared on the surface of Chu Xun's skin, making his whole person look as if he was bathed in the morning glow, which was extremely mysterious.

And with the continuous infusion of biological energy, Chu Xun's gene chain full of cracks like broken porcelain began to be gradually repaired. The ant gene, the tyrant gene, and the alien gene all began to stabilize one after another, and then quietly stayed in their own blank gene chain, gradually fusing perfectly with Chu Xun's own genes.

"This kid ......" Looking at Chu Xun, who had fused all the five second-order red crystals in an instant, Chu Madman's pupils also shrank slightly, and a trace of disbelief flashed in the depths of his eyes.

That's right, the crystal nucleus can indeed strengthen a person's body and abilities, and the second-order red crystal is even better. But just as a person will have strength when he eats a full meal, but he will die if he eats too much at one time, there is an upper limit to the amount of crystal nucleus energy that everyone can absorb in a short period of time.

Generally speaking, a first-order ability can only absorb a maximum of ten crystal nuclei in a day, while a second-order ability can be ten times that number. However, at this moment, Chu Xun had absorbed the energy equivalent to three thousand standard crystal nuclei at the same time, even if the absorption efficiency of the second-order red crystal was higher, but this kind of energy intake was far beyond the limit that his class could accommodate.

It can even be said that even a third-order ability cannot withstand such terrifying energy. If you insist on absorbing it, then the only result is that the energy overload explodes and dies.

But looking at Chu Xun's current appearance, it seems that not only is he fine, but he also has spare energy. This made Chu Madman shocked by Chu Xun's strangeness again, and he also wanted to know what kind of surprise this guy who was originally unknown but now became a blockbuster could bring him.

The energy contained in the three second-order red crystals was indeed huge, and as these energies were gradually absorbed by Chu Xun, Chu Xun's gene chain finally began to heal gradually, and at the same time, a new gene vacancy began to slowly appear on his gene chain. In other words, with the infusion of such a huge amount of energy, his insect body was finally about to advance again.

Sure enough, when the last gene vacancy was completely formed, the red light on Chu Xun's body also disappeared abruptly, and at the same time, the prompt sound of the system also sounded from his head.

"Drop, the host is replenished with bioenergy, the insect ability is enhanced, the ant gene is strengthened, the alien gene is strengthened, the tyrant gene is strengthened, and new gene locks are unlocked."

"Please note: Before obtaining enough biological energy and being strong enough, the host should not devour the fifth gene to avoid the collapse of the host gene chain."

And with the enhancement of the insect body ability and many genes, a terrifying aura that made people palpitate suddenly appeared on Chu Xun's body, as if something extremely terrifying had been released from his body.

At the same time, Chu Xun's body also showed some subtle changes, his muscles became tighter, and his muscle groups became more dense and coordinated. Although his appearance has not changed much, the whole person standing there seems to be more coordinated, as if as long as he is willing, he can turn from static in the next second, and burst out with extremely terrifying power.

"Good boy!" As a strong man, Chu madman was the most sensitive to the changes in Chu Xun's breath, and felt Chu Xun's sudden strong breath and the more coordinated body, Chu madman couldn't help but praise secretly.

Obviously, this guy's whole person had undergone a qualitative change after fusing three second-order red crystals, and he had become even more powerful.

However, the Chu madman didn't know that what he saw was only the external changes of Chu Xun, but the real transformation of Chu Xun was internal.

Because with the repair of the gene chain and the advancement of the insect ability, his three genes have finally fused together perfectly, which means that he can now exert his true power without any scruples, so as to have the powerful combat power when he killed the poisonous spider in the first place.

In other words, in a way, he's now a true second-order powerhouse!

But more importantly, with the opening of the fourth blank gene lock, Chu Xun can now finally start devouring that spider's gene. And with the integration of spider genes, his combat power will once again get a qualitative leap.

At that time, it will no longer be impossible for him to defeat Chu Qing!

Thinking of this, Chu Xun also felt that his whole body was excited.

……

Meanwhile, the ruins of Dead City No. 7.

After the aftermath of a series of strong battles and the final nuclear explosion, the Dead City of No. 7, which originally stood in the valley, was completely razed to the ground, except for some fortifications on the edge that left a little bricks and rubble, the buildings in other locations had already been completely shattered, and the central control base at the core of the explosion was completely destroyed, leaving only a deep pit.

It had only been a day since the explosion, and although the flames of the ruins had been extinguished, the heat had not yet dissipated, and melted steel and flowing molten lava could be seen everywhere. Anyone who looks at this place will think that this is a volcanic crater that has just erupted, not a city that has been completely destroyed.

In addition to the terrible heat, the intense radiation also made it completely deadly. Even the most tenacious zombie creatures will be drained of their vitality by radiation after staying in this kind of place for a long time, and finally turn into dry corpses like rotten wood.

However, it was in this place where people and animals were exhausted that at this moment, a long-haired woman wearing a white doctor's robe, with a slender and plump figure and an almost perfect face appeared.

The woman was walking in the ruins full of radiation and molten lava, but she seemed to be walking in a beautiful back garden. She was still watching as she walked, and her mouth was also thinking about something, and at the same time, her delicate brows furrowed from time to time, as if she was wondering why things were going on.

This woman in a medical robe is none other than Nangong Yan, who left Satellite Town No. 4 not long ago. For some reason, she had to make a trip to Dead City Seven to search for clues about the panacea.

"No, why is it that the closer you get to the center of the explosion, the lower the radiation index?" The closer she got to the center of the explosion, the more doubts Nangong Yan had in her heart, especially when she walked to the center of the explosion that originally belonged to the central control base, but now it was a big pit, the doubts in her heart became even stronger.

This is because the amount of radiation left here is much lower than in other places, as if something has sucked the residual radiation out of the place.

"What the hell is sucking the radiation out of here?" Nangong Yan frowned and began to search for clues, and soon, a row of human footprints embedded in the ground attracted her attention.

The footprints extend outward from the center of the explosion, meaning that someone has left the center of the explosion before. As for why the footprints were embedded in the ground, it must have been at the end of the explosion that the ground here was full of molten lava, so the person would walk through it as if he was stepping on the soft mud floor.

So, who exactly can get out of the center of a nuclear explosion? And is he the one who sucks the radiation?

Thinking of this, Nangong Yan narrowed her eyes slightly, and then quickly chased after her in the direction where the footprints left.

She had a gut feeling that if she found that person, she should be able to solve all her doubts!
