Devouring energy is actually a very comfortable thing, and the feeling of constantly pouring energy into the body will make people feel a unique sense of satiety and feel comfortable physically and mentally.

But if everything is too much, so is devouring energy. Just like you eat and drink, you can give you a delicious experience, but if you are constantly poured water and stuffed with food, it can be called torture.

And Chu Xun's feeling at this moment is exactly like this!

Almost as soon as he came into contact with the giant crystal, Chu Xun felt a surge of surging energy completely envelop him, and then began to pour into his body in a steady stream.

This energy was so huge that even Chu Xun's strong body couldn't digest it in a short period of time. Soon, under the swarm of these forces, Chu Xun began to feel that every cell, every meridian, and even every blood vessel in his body was filled with these terrifying powers.

But after filling every inch of Chu Xun's body, these energies were still pouring into his body. As a result, Chu Xun's cells, meridians, and blood vessels began to burst one after another under the endless infusion of these energies.

His capillaries began to burst open, his internal organs began to bleed, his meridians began to be damaged, and in less than half a minute, Chu Xun was as if he had been beaten by a seventh- or eighth-order powerhouse, and he was deeply injured.

However, while being hit hard, a large part of these forces were still absorbed by Chu Xun. And these powers absorbed by Chu Xun were also quickly transformed into powerful vitality, and began to heal Chu Xun's body quickly with the self-healing ability brought by Chu Xun's devouring mutant cockroach king genes.

As a result, Chu Xun's body also began to be constantly damaged and recovered, and the speed of damage and recovery was almost the same, neither allowing Chu Xun to heal completely, nor making Chu Xun's injuries more serious, and he died on the spot.

And in this continuous damage and healing, Chu Xun's body is also like a piece of steel that has been tempered for thousands of years, becoming stronger and stronger, and at the same time, with the integration of a large amount of biological energy, Chu Xun's insect body ability has also begun to be slowly strengthened, and the prompt sound of the system has also continued to sound from his mind.

"Drop, the host is replenished with bioenergy, the worm's ability is enhanced, and the gene lock is turned on by 1%......"

"Drop, the host is replenished with bioenergy, the worm ability is enhanced, and the gene lock is turned on by 2%......"

"Drop, the host is replenished with bioenergy, the worm's ability is enhanced, and the gene lock is turned on by 3%......"

With the support of a huge amount of energy, Chu Xun's insect ability began to become stronger and stronger, and he was getting closer and closer to advancement. At the same time, under the influence of the strengthening of the insect's ability, Chu Xun's body was further strengthened, and he began to gradually adapt to the infusion of this huge amount of energy, and the sharp pain of the meridians, cells, and blood vessels all over his body being torn and shattered gradually began to become weaker.

Everything is developing for the better!

"Drop, the host is replenished with biological energy, the insect ability is enhanced, the gene lock is 100% open, the ant gene is strengthened, the alien gene is strengthened, the tyrant gene is strengthened, the spider gene is strengthened, the scarab gene is strengthened, the cockroach gene is strengthened, the praying mantis gene is enhanced, and the new gene lock is successfully unlocked."

"Please note that until enough biological energy has been obtained and the body is strong enough, the host should not devour the ninth gene to avoid the collapse of the host gene!"

Finally, after lasting for an unknown amount of time, the energy devoured in Chu Xun's body also reached a limit, and then broke through Chu Xun's shackles and opened a new genetic lock for him.

At the same time, a huge and incomparably large force also began to pour out of Chu Xun's body. Under the effect of this special force, Chu Xun's body began to become stronger and larger, and the exoskeleton armor on his body became thicker, and at the same time, it became more dark. Those brilliant energy rays shone on it, as if they had encountered a black hole, and they were swallowed up in the blink of an eye, and it was impossible to illuminate half of it.

And that's just the beginning of change.

With the surge of power brought by the advancement, the fleshy wings behind Chu Xun also became larger. At the same time, the claws at Chu Xun's fist bones also became more slender, sharper, and flashed with a cold luster, which made people chill.

By the time all the changes were over, Chu Xun had skyrocketed into a terrifying giant with a height of five meters, wearing black heavy armor, wings on his back, and a long alien tail behind him. At this moment, he was like a demon who had come out of an ancient myth, constantly rising and falling in that brilliant blue light, and the aura of the whole person became more violent and powerful.

"Isn't it over yet?"

Feeling the power of the outside world still pouring in, Chu Xun suddenly felt happy in his heart. At this moment, he has successfully advanced, and his body's defense, carrying limit, recovery ability, and devouring energy have all been qualitatively improved. Although the energy that was constantly pouring out of the crystal was huge, it was no longer enough to pose a real threat to him, but it continued to strengthen his body, making him stronger and stronger.

It wasn't until this moment that Chu Xun really knew that he had underestimated the energy reserves of this million-person city after all. However, this can be regarded as a bonus, after all, the more energy he incorporates, the stronger he becomes, and the more likely he is to withstand the next nuclear explosion.

As a result, Chu Xun also began to concentrate his mind and absorb the energy of the outside world to strengthen himself, hoping to go one step further with this huge power, if he could successfully advance to the 7th order, then even a nuclear explosion might not be able to threaten him.

However, Chu Xun still underestimated the difficulty of improving the insect body ability after all, although the external forces were constantly integrating into his body at this moment, his body was like a bottomless pit, absorbing as much energy as he could, and it was simply impossible to refuse, but the progress of the insect body ability became extremely slow.

Before he advanced, Chu Xun could basically hear a system prompt every 5 seconds or so, which meant that it only took him less than 10 minutes to break through from the 5th order to the 6th order.

However, after advancing to the 6th level, although his devouring ability has been greatly improved, and the power integrated into his body has become even greater, the frequency of the system prompt sound has been more than 10 times slower! What used to take him 5 seconds to hear now takes a full 1 minute!

And now it is only more than 20 minutes before the nuclear explosion, which means that it is impossible for Chu Xun to complete the second advance before the nuclear explosion!

Soon, Chu Xun also realized this, but the only thing he could do now was to devour the energy with all his might, after all, every time he devoured an extra point of energy, he would have an extra chance of survival!

"Warning: The energy system will self-destruct in 30 seconds!"

"Warning: Only 30% of the energy system reserves energy, implement a first-level self-destruct program, reduce the energy supply of the energy shield, and maintain the self-destruct program!"

"Warning: Base nukes will detonate in 30 seconds!"

Time passed slowly in the process of Chu Xun devouring the energy with all his might, and in the last few tens of seconds, the violent alarm sounded again.

Only this time, the alarm sounded differently than before!

"Host, things have taken a turn for the better!"

"Most of the reserve energy in the Energy Center of Blood and Bone City has been absorbed by the host, and in order to ensure the power of the energy system's self-destruction, the energy system has independently weakened the energy shield and gathered more energy here!"

"If the host flees now, then as long as the energy shield is weakened by the self-destruction of the energy system and the nuclear explosion detonation money, and escapes from the City of Bones, the host's chance of survival will be increased to 35% without having to bear the frontal impact of the nuclear explosion!"

"Please get out of here now!"

And almost at the same time as the piercing siren sounded, a series of prompts from the system also sounded in Chu Xun's mind.

After working hard for so long, Chu Xun finally ushered in the dawn of life!

"Got it!" Hearing the system prompt, Chu Xun's eyes froze, and then the huge bone and flesh wings behind him slammed away, and the whole person instantly rushed out of the electromagnetic field like a black lightning, flying towards the outside world at an extremely fast speed.

At the same time, above Bloodbone City, the piercing countdown continued.

Chu Xun's time is running out!

It's 30 seconds of life and death!
