In the night, violent wind waves roared, sweeping up smoke and dust all over the sky.

A strong wind blew as Chen Chu stepped into the void, his long black hair fluttering behind him. He looked like a god looking coldly down below, where a crack stretched for dozens of kilometers and was bottomless.

With Chen Chu's strength in his prime, one strike was enough to destroy an area of ​​hundreds of kilometers, shatter the void, and the destructive impact of the explosion would spread over hundreds or thousands of kilometers.

Compared with those countries with smaller territories, this range can be considered as destroying a country in one blow.

Although this 'country' is a bit small.

Even if he cannot mobilize the power of rules now, he can use his physical strength to destroy Tianxuan City in one blow and wipe out all the mutated monsters.

However, this would also destroy the National Library, so a slightly more troublesome method was chosen, which was to circle the city dozens of times with extreme speed and power to flatten it.

Of course, another reason is that he likes the feeling of blasting everything, just like he doesn't like to eliminate air resistance when flying at high speed and likes to create sonic booms.

This kind of 'punch to the flesh' feeling of seeing monsters explode into blood mist under the halberd is very satisfying, but it's a pity that it's just a peak level nine monster, not strong enough to fight.

With emotion, Chen Chu put away the Eight Desolations War Halberd and returned to the library.

Looking at Chen Chu flying down from the sky, Shi Feirou and her sister were stunned and subconsciously asked: "Mr. Chen, those mutant monsters...?"

Chen Chu smiled slightly: "It's all been solved."

Amazing. Sister Shi Feirou was amazed, but only for a moment.

From the time they met Chen Chu until now, they have become accustomed to being shocked.

Under the bright light, the three of them then flipped through the hundreds of thousands of ancient books on the bookshelf, and finally collected more than a hundred cultivation techniques.

Most of them are ordinary skills left behind by high-level practitioners. After thousands of years, most of them are incomplete and are of no use to Chen Chu except as a reference.

There are seventeen body-refining exercises, and the most powerful one is a complete body-refining exercise that can be cultivated to the ninth level, the Great Sun True Body, the complete version of the Red Sun Exercise.

After brushing off the dust, Chen Chu collected dozens of secret books. Looking at the dusty faces of Shi Feirou and her sister, he smiled and said, "Thank you for your hard work."

Today’s harvest made Chen Chu in a good mood.

The emperor's inheritance obtained during the day solved the problem of time erosion and mastered a powerful magical power. This time he also successfully found a large number of body-refining exercises.

Next, as long as he takes the time to practice everything and constantly adjusts and studies, he should have hope of success.

Shi Feirou, who has a voluptuous figure and a resolute look in her eyes, gives people the feeling of a strong woman, shook her head and said softly: "Compared to the help Mr. Chen has given us, this little thing is not worth mentioning."

The exquisite and beautiful Shi Feitong also nodded in agreement: "Yes, my sister and I didn't do anything, Mr. Chen, you don't have to be so polite."

After a few polite words, the three of them jumped back to the rooftop, and the two sisters were stunned.

In the dim night, the surroundings were empty except for the broken and uneven earth. Tianxuan City and the countless mutant monsters hidden there had all disappeared.

Only then did the two women come to their senses and understand what Chen Chu meant by "it has been resolved".

Everything was indeed solved, except that the entire city was wiped out. Such terrifying power once again made them certain that Chen Chu was a powerful man from ancient civilization.

call!

Amid the eruption of hot air waves, the dark red fighter plane slowly rose into the air, and then exploded into the air with a bang, accelerating to three times the speed of sound within a few seconds.

Roar! Just as the fighter plane flew a few hundred kilometers, a huge black shadow rose into the sky from the forest below, roaring violently.

boom!

A dazzling white beam of energy pierced through the sky and earth, and the light it emitted illuminated half of the sky. A shot from the main gun directly blew up the head of the eighth-level pterosaur monster.

Roar, roar, roar! ! At the moment when the giant pterosaur was killed, the powerful energy fluctuations attracted the attention of mutant creatures within a radius of hundreds of kilometers.

But at this time, fighter planes had already appeared in the sky.

The mutant monsters were more active at night. On the way back, missiles on both wings of the fighter plane roared, machine guns under the belly roared, and two deputy and one main energy cannons continued to erupt.

After almost using up all the ordinary crystal energy missiles in stock, the fighter plane returned to the sky above the research base. The lights below turned on, the magnetic levitation started, and it slowly descended in a strong wind.

The ferocious-looking, sci-fi-style fighter jet immediately aroused the vigilance of everyone in the base.

"careful."

"Everyone, don't go out."

Gao Tianxiang and others guarded the entrance to the mountain wall, looking at the huge fighter plane that crushed several small trees with solemn and shocked expressions.

It was the first time they saw such 'high-tech' things.

Click! The door behind the abdomen opened, revealing the figures of Shi Feirou and Chen Chu. Everyone paused for a moment, then looked excited.

"It's the division captain."

"And that powerful young man."

"What young man? That's Mr. Chen Chuchen."

As Gao Tianxiang and others spoke, they hurried forward, and behind them, a dozen young men ran out cheering.

"Sister Rourou, you guys are back. Why are you sitting there?"

"Sister Tongtong, what is that? Is it a plane?"

Chen Chu did not go down, but quietly watched Sister Shi Feirou being surrounded by people asking questions. After a while, he said, "I will be in seclusion for a few days. Don't disturb me if you have nothing else to do."

"Retreat." Shi Feirou and others paused.

At this time, Chen Chu continued: "These are two energy crystals. You can hold them in your hands when you practice. The energy contained in them can help you practice."

As he spoke, Chen Chu handed two fist-sized golden crystals to the two of them, and then without waiting for them to ask, he turned around and entered the fighter plane.

Looking at the hatch door that clicked shut, everyone looked at each other.

This strong man named Chen Chu seems a bit aloof.

To practice the ancient body-building exercises, strong blood is only a basic requirement. Under normal circumstances, one must also absorb the energy of heaven and earth to make rapid progress.

It’s just that the mutated virus in this world has caused all living things to evolve, giving them terrifying endurance and strong physiques, so they can practice simply with blood and energy.

Each of these body cultivators who can cultivate to a high level or even a high level in a barren environment is actually a genius. If they appeared in the mythological world, their strength would surely improve by leaps and bounds.

Just like the First Senate Chairman of Blue Star and others.

As one of the first powerful people awakened by the changes in heaven and earth, he has terrifying talents. Coupled with the inheritance of the king of ancient civilization, he directly became the strongest in a short period of time.

The two energy crystals were the reward given by Chen Chu to thank them for their "trip".

Arriving at the Yunxiao training area, Chen Chu sat down cross-legged and took out the Dark Star Battle Body that interested him. His eyes were like a scanner as he memorized all the contents and patterns.

After a while, Chen Chu put it down thoughtfully.

Just like the Scarlet Sun Body Refining Technique, the Dark Star Battle Body was also tailored to the 'physique' of the ancient human race. If Chen Chu wanted to get started, he still had to change his physique first.

As for the powerful physique of innate awakening and the prerequisite training requirements of metal compatibility talent, they can be directly ignored.

After all, no congenital awakener can compare to his physical body. As for his talent for metal compatibility, it is to prevent himself from being unable to control metal during the initial stage of cultivation and the absorbed heavy elements from damaging his body.

Crack, crack! ! Under Chen Chu's control, the flesh and blood of his body moved, and the meridians and acupoints were adjusted, and the physical simulation of the ancient human race was quickly completed.

Then Chen Chu moved his mind, recited the formula silently, mobilized a wisp of blood and energy, and circulated it along more than a dozen unfamiliar meridians with unstoppable force.

Boom! In just a few tens of seconds, Chen Chu entered the first level of the Dark Star Battle Body, as easy as drinking water.

However, Chen Chu stopped here, and a black stone the size of a washbasin appeared in his hand, with a metallic luster and mysterious texture on the surface.

This stone came from the storage equipment of a demon king. Chen Chu didn't know what specific mineral it was, but he only knew that this mineral was very heavy and hard.

Just a piece this big weighs hundreds of tons.

At the same time, Chen Chu's voice sounded in his mind: "Consume 100 attribute points to strengthen the second level of the Dark Star Battle Body."

After mastering the technique, you can directly enhance it with attribute points.

At the moment when the one hundred attribute points disappeared, a surge of strengthened energy poured into the dark star's blood, causing it to riot instantly, running wildly at a speed dozens of times faster than before.

And in the process of circulation, it separated out thin strands of qi and blood, which penetrated some of the tiny meridians in Chen Chu's body, and finally formed a "net" that covered the black ore.

Buzz! Under the blood and qi net that seemed to cover the "planet", the hard and heavy ore vibrated slightly.

In Chen Chu's perception, wisps of weak metal elements were transformed by the Qi and blood network, and wrapped in Qi and blood, they flowed into his body through his hands and circulated together.

The moment these heavy metal elements entered Chen Chu's body, a strong stimulation erupted, and the meridians wherever they passed... vibrated slightly.

If it were a low-level practitioner who had just started practicing, his meridians would be instantly pierced by the heavy metal elements entering his body, and he would then need to spend time warming up and repairing himself before continuing to practice.

After thirty-six consecutive cycles, when all the meridians in the second layer have become tougher and stronger with the incorporation of heavy metal elements, you can try to break through the third layer.

Moreover, the cultivation of the Dark Star Battle Body has hierarchical steps. The first step is to absorb ordinary metal elements, and the third step is to absorb stronger and more metal minerals.

As for Chen Chu's current practice, he is completely cheating.

boom!

Strengthened by the mineral elements of the god-level material, the Qi and blood in Chen Chu's body circulated more than a hundred times within two minutes, directly breaking through the third level.

Without wasting time, Chen Chu's thoughts continued to echo in his mind: "Consume 400 attribute points to strengthen the fourth level of the Dark Star Battle Body."

In an instant, even more violent and powerful energy exploded in Chen Chu's body, emitting a dark red blood and energy riot, which exploded into a dense blood and energy network that enveloped his entire body.

At the same time, the black ore in his hand, which had shrunk in size, vibrated and was covered by a dark red blood net that seemed to be real, gradually turning gray.

Chen Chu perceived that more heavy metal elements were absorbed into his body, circulated along the blood and qi to cover his entire body, and gradually merged with the skin and membranes.

This fusion is very peculiar. Under the transformation of Qi and blood by the exercises, the forms of those heavy elements have changed and become somewhere between matter and energy.

After fusing with Chen Chu's skin and the membrane underneath, the flesh and blood properties of the skin remained unchanged, but it had a touch of metallic hardness and heaviness.

And as he absorbed and fused more and more heavy metal elements, his skin membrane became stronger.

Although with Chen Chu's current physique, the enhancement of skin hardness is barely noticeable and has no effect on his strength, the nature of the transformation makes him more interested.

"Consume 600 attribute points to strengthen the fifth layer."

"Consume 800 attribute points to strengthen the sixth layer..."

Boom boom boom! ! With Chen Chu's unconditional strengthening, the Dark Star Qi and Blood Power in his body continued to surge, breaking through to the sixth level with unstoppable force.

The sixth level of the body-refining technique covers muscles all over the body. Under the continuous fusion and absorption of black heavy metal elements, the muscle fibers also possess the heavy characteristics of metal.

And under the microscopic control of Chen Chu's spiritual will, some muscle cells have changed, madly absorbing heavy metal elements, compressing and storing them, and gradually emitting a metallic luster.

When the entire cell turned black and gold, like a metal "planet", a weak gravitational magnetic field emanated from inside the cell.

A single cell did not change much, but when the black ore in Chen Chu's hand completely turned gray, millions of muscle fiber cells throughout his body had transformed.

"It's not enough." Chen Chu suddenly opened his eyes and took out a larger piece of black ore in his hand, while the thought sounded in his mind.

"Consume 2,200 attribute points to strengthen the seventh and eighth levels of the Dark Star Battle Body."

boom!

The violent enhanced energy exploded, and Chen Chu's entire body was enveloped in dark golden light, exuding a domineering aura as heavy as a mountain, and the fighter plane under him sank slightly.

Under the circulation of the powerful qi and blood, wisps of dark golden light that seemed to be real enveloped the black ore, rotating in nine layers inside and outside, containing some kind of ultimate truth.

As the technique was running, even heavier and sharper heavy metal elements poured into Chen Chu's body, passed through his muscles, and merged into his bones under the circulation of qi and blood.

As the heavy metal elements of these god-level materials were integrated, some black lines appeared on the surface of the originally pure gold bones, which were somewhat similar to the innate runes on the giant beast's skeleton.

At the same time, while practicing, Chen Chu was also observing the changes and directions of the exercises, and verifying them with his own "body".

This time he practiced for about half an hour. Only when the ore weighing more than 200 tons cracked and turned into grayish-white stone and fell to the ground did Chen Chu open his eyes.

There was a hint of surprise in Chen Chu's eyes: "My physical strength has actually increased a little."

The eighth level of Dark Star Combat Body increased Chen Chu's physical strength a little, but the improvement did not seem to be significant.

But you have to know that his current physique is comparable to that of an early Titan beast. Even if it is only one thousandth of the improvement, the increase in "strength" is very terrifying.

And this is only the eighth level, which is equivalent to the realm of the eighth-level cultivator. If one can cultivate to the ninth or tenth level of the mythical realm...

Unfortunately, this martial art only has the eighth level. Chen Chu summoned the attribute page with a thought.

Skill: Dark Star Battle Body + [Eighth Level]

When Chen Chu's eyes fell on the + sign behind the Dark Star Battle Body, a row of transparent text appeared in front of him: "Do you want to consume 3,000 attribute points to strengthen the Dark Star Battle Body to the limit?"

Extreme enhancement is a special function of the attribute page. It can consume attribute points and enhance the skill to the highest level.

The low-level skills that Chen Chu initially practiced, Dragon Elephant Skill and Mind Eye Sword Skill, became even more powerful after being strengthened to the limit, and even evolved into 'talent' runes.

Unlike high-level skills that have an upper limit of only six levels, the upper limit of ancient body-refining skills is higher, deduced to eight levels or even up to nine levels.

The reason is that the power systems of the two sides are very different, and the old and new eras are different.

The ancient techniques that were practiced at a higher level were actually weaker than the Zhenwu that Blue Star was currently practicing, and were not as comprehensive as those practiced by modern practitioners.

Especially the top secret book practiced after the seventh level, not only the real body is unparalleled powerful, but also the virtual image of Zhenwu can be condensed to control the power of heaven and earth, and the combat power span is even greater.

But for Chen Chu, these ancient skills also have an advantage, which is that they can be strengthened to the extreme.

Bang! Chen Chu took out a several-meter-high, platinum-colored ore from the storage space. Instantly, the entire Yunxiao fighter plane shook violently, as if a small mountain was crushed.

If the fighter plane was not made from the remains of mythical beasts, it would have collapsed and crushed through.

"Consume 3000 attribute points to strengthen the Dark Star Battle Body to the extreme."

boom!

A surge of enhanced energy exploded in Chen Chu's body, and the dark star blood, which had reached its limit, exploded and turned into a thick dark golden blood mist that spread throughout his body, covering both the man and the ore.
