Chu Xun didn't know that someone had cleaned up the traces of the battle for him after he left, and at this moment he had returned to his home. But compared with the calmness when he left home, his appearance at this moment looks much more embarrassed.

Boom!

With a muffled sound, the door was directly closed by Chu Xun, and then he put the things in his arms on the table, and carefully untied the cloth tied around his neck.

At this moment, the strip of cloth had been corroded by the acidic blood, turning into some rags, but at the same time, the wound on his neck had completely stopped bleeding and was gradually healing.

Standing in front of the mirror, Chu Xun carefully observed his wounds. However, what surprised him was that at this moment, a faint white light was flickering at the wound, and at the same time, there seemed to be a trace of warm current in his body converging towards the wound.

Soon, an even more astonishing scene happened. I saw that under the action of this white light and warm current, some extremely thin and tiny whiskers began to grow on Chu Xun's neck, which had been torn by nearly half. The tendrils were like sutures, twisting his wounds together and speeding them to heal.

"What the hell are these white lights and warm currents?" Feeling the tingling and tingling from his neck, Chu Xun knew that this was a sign that the wound was healing rapidly. It's just that his heart is full of puzzlement, what is this white light and warm current that can speed up the healing of his wounds?

After all, in his impression, neither the alien gene nor the ant gene should have this magical power. So the question is, how can he have the power in his body that even he can't figure out?

After thinking about it for a long time, Chu Xun didn't come up with an answer, and at this moment, the wound on his neck had been automatically glued together, and soon only a faint trace remained, and it was estimated that it would not be long before these marks would disappear completely.

"Forget it, I don't want to, it's not a bad thing anyway......" Shaking his head, Chu Xun took a deep breath and decided not to think about this question anymore.

There are too many secrets on him, the super savior system is one, and this strange warm current and white light is another, since he can't find the answer now, then he can only go with the flow.

After wiping the blood on his neck a little, Chu Xun opened the metal box on the table again, and then the soft blue light appeared again, illuminating the room brightly.

"Tut, if you don't die, there will be a blessing in the future......" Looking at the twenty standard crystal nuclei neatly placed in the metal box, a trace of excitement suddenly flashed in Chu Xun's eyes.

He didn't expect that there would be so many crystal nuclei on the body of just one killer!

This is also to blame the ghost blade for being unlucky, due to Chu Jie's wrong information, the ghost blade regarded Chu Xun as an ordinary person who had no power to fight back, so he brought the crystal nucleus with him. As a result, he didn't expect that not only did he not complete the task, but he also lost his life, and even these twenty crystal nuclei became Chu Xun's trophies.

"Great, if I can use these crystal nuclei to open another gene lock, then I will be more confident of winning the first place in the student assessment!" Looking at these standard crystal nuclei that shimmered with soft brilliance, Chu Xun felt a burst of excitement in his heart, and then quickly took out a crystal nucleus and held it in the palm of his hand, and began to close his eyes and fuse.

Airplanes!

Just like last time, the crystal nucleus began to tremble slightly, and then turned into blue light and merged into Chu Xun's body. At the same time, the cold voice also sounded in Chu Xun's mind as promised.

"Drop, the host is replenished with biological energy, the energy of the insect body is strengthened, and the gene lock is opened by 1%."

“1%？” Hearing the hint in his mind, Chu Xun trembled all over, and opened his eyes suddenly, with a look of disbelief on his face.

He was a little skeptical if he had heard it wrong, the last time he fused the crystal nucleus, the degree of opening of the gene lock was 10%!

Could it be that every time the gene lock is opened, the crystal nucleus required is ten times as much as the previous one?

Thinking of this, Chu Xun's face suddenly became extremely ugly.

He might be able to get a hundred crystal nuclei if he thinks of a way, but what if it's a thousand, ten thousand, or even a hundred thousand? This number, I'm afraid that even Chu Xiong, who is the lord of a city, will be moved by it!

"It seems that after the student assessment, he must find a way to get more crystal nuclei......" After muttering for a long time, Chu Xun sighed heavily, because the surprise of accidentally getting twenty standard crystal nuclei was also swept away, but he also felt a pressure out of thin air.

"There are still nineteen crystal nuclei left, but we can't waste them......" Moving his gaze to the crystal nucleus again, Chu Xun frowned slightly.

In this situation, fusing only a dozen crystal nuclei is of no use to his strength, so instead of wasting them in vain, it is better to use these crystal nuclei in more useful aspects.

Like aliens?

Thinking of this, Chu Xun summoned the alien again, wanting to see if this crystal nucleus could be useful to the alien. After all, if he can improve the strength of the alien, then his comprehensive combat power will also have a huge leap.

You must know that even with his current strength, he is not sure of winning against the alien in his full body form!

But it's a pity that this guy seems to be only interested in the primordial crystal nucleus and fresh flesh and blood, and in the face of the standard crystal nucleus that flashes with soft blue light, this guy doesn't look at it, so he squats directly beside Chu Xun, like a small pet.

Seeing this scene, Chu Xun sighed helplessly, although the alien body grew a little longer after devouring the corpse of the ghost blade, it was still not enough to see......

Finding that there was no place to use the crystal nucleus now, Chu Xun simply put away the remaining crystal nuclei for backup. Then he picked up the other trophy he had found from the corpse of the ghostblade, the animal skin booklet, and flipped through it.

"Interesting...... The animal skin booklet is not thick, it is only about forty or fifty pages, but after only turning a few pages, a look of surprise clearly appeared on Chu Xun's face.

There is no name on this animal skin booklet, and the things written in it are also a mess, and it seems that some of the experiences and experiences recorded by Ghost Blade are casually recorded.

However, these things are not inferior to those crystal nuclei in their value to Chu Xun. You must know that this is the brainchild of a killer's life, which not only analyzes the structure and vital points of the human body in great detail, but also specifically annotates how to destroy these vital points with the least force and kill people.

In addition, the booklet also contains a lot of recipes for poison and tips for setting traps. Although Chu Xun couldn't become a master of poison use or a master of traps with just this booklet, it was enough for him to understand and guard against it.

And most importantly, Ghost Blade also had adventures outside in his early years, and he had a lot of knowledge about how to deal with zombie creatures and mutated creatures, so there are a lot of notes on dangerous creatures in the booklet.

These things are all valuable experiences accumulated with blood, and for Chu Xun, who is a rookie, they are even more priceless!

"I have to say, this time the harvest is really rich......" After taking a deep breath, Chu Xun put away the animal skin booklet.

Although this animal skin booklet is not thick, it contains a lot of content, and it is not an overnight thing to master it completely.

And for him now, the most important thing is to go to the Battle Skills Hall to receive systematic training, so that he can improve his actual combat ability as soon as possible, as for the content in this booklet, he can wait for the end of the special training to study.

Therefore, after putting away the crystal nucleus and the animal skin booklet, Chu Xun also immediately found a wet towel to wipe his whole body, wiped off all the blood stains, and finally put on a new dress, and prepared to go out to the Battle Skills Hall again.

On the way to the Battle Skill Hall, Chu Xun once again passed by the alley where he fought with the Ghost Blade, but to his surprise, the traces of battle in the alley had completely disappeared, and even the potholes on the ground that had been corroded by his blood had been restored to their original state, as if nothing had ever happened.

"Hey, who helped me deal with the battlefield?" Seeing this scene, Chu Xun frowned slightly, then chose another path and continued to move forward.

Now that the sun had fully risen, the temperature had risen, and the streets were getting more and more populous, he didn't want to stay here for long, lest he cause unnecessary trouble.

It's just that the slightest doubt is still entangled in his heart and can't be dissipated......

Chu City is not very big, and it didn't take long for Chu Xun to come to Xicheng District.

The Battle Technique Hall and the War Law Hall are both located in the Xicheng District of Chu City, which is the most lively place in the entire Chu City, because in addition to the War Skill Hall and the War Law Hall, there is also the largest free market in the city, as well as the Bounty Pavilion that specializes in releasing bounty tasks.

As soon as he arrived in Xicheng District, Chu Xun felt a different taste.

Compared with the clean and tidy aristocratic district in the north of the city, Xicheng District is much more noisy, dirty, and chaotic. It is a place where you can see a mix of fish, whether you are a commoner doing small business, a bounty hunter who hunts dangerous creatures for a living, or a supernatural person from a major family.

However, even the most chaotic place in this area is also the most orderly and egalitarian place in the whole city. Because here, even the descendants from the major families dare not be presumptuous and bully. Because no one knows if this seemingly ordinary guy in front of you will be a powerful powerhouse with blood on his hands.

This kind of thing is not uncommon, and many strong people like to play pretending to be pigs and eating tigers, and they are hidden in the city. Of course, they do this more in the hope of blending in with the crowd to relax their minds, after all, the intensity of killing and fighting can sometimes make people too nervous to recover long after the battle.

This situation was very common before the end of the world, and those soldiers who retreated from the battlefield needed a long time to adjust themselves. And this disease also has a very apt name, that is, "war traumatic sequelae".

In short, after experiencing several bloody lessons, especially when a small nobleman was destroyed by a strong man with a distorted psychology because he insulted a strong man, the west of the city has become such a place where there is order in chaos and relative equality between respect and inferiority.

"It's here!"

The Battle Technique Hall and the Battle Law Hall are both located at the entrance of Xicheng District, so it didn't take long for Chu Xun to come to the destination of this trip - the Battle Technique Hall!

"Stop!" However, as soon as he came to the door of the Battle Skill Hall, two loud shouts suddenly came into Chu Xun's ears, and in the next second, Chu Xun was firmly grasped by two people!
