Du Bixing's skin gradually reddened, and sweat evaporated into white gas, which was emitted around his body. According to the description in "Fighting Chapter", the first step in refining the body is copper skin, the second step is iron bones, and the third step is blood refining.

These are the three basic steps of physical strengthening, and only after the foundation is stabilized can you practice the Force and become an intermediate primordial martial artist.

What Du Bixing has to do now is to cultivate the "copper skin" first. Turns your skin into the same as a Bone Pig, with defense that can't be damaged by a normal sword.

The active molecules and energy in the blood of the alien beast were slowly absorbed by Du Bixing, and the degree of evolution was slowly increasing.

79 percent, 80 percent...... Ninety percent, the further you go, the slower the increase in physical strength.

At about 95 percent, Du Bixing felt that he had been unable to improve. The ball girl suggested, "Master, you can try the Star Guiding Technique to promote the evolution of your body. ”

Du Bixing did so, or played the eighteen sets of actions in the guidance operation. Sure enough, this bizarre action is also promoting the body's absorption of nutrients and the Force, and his cells begin to evolve again.

In the sparsely populated primeval forest, on an exposed rock, Du Bixing was playing the action of guiding. His muscles, blood, and meridians were strengthened and tempered through the Channeling Technique, and they were strengthened step by step.

The sun shone on him, and Du Bixing's originally reddened skin gradually appeared with a metallic luster, like bronze pouring.

"Ninety-nine percent evolution, master, come on!" the ball girl floated in front of Du Bixing, cheering him on.

At this time, Du Bixing felt a sharp pain in his skin. It was as if hot metal liquid had been poured on it, burning his skin. The two sensations of pain and burning are intertwined, and they are all over the skin.

Du Bixing's forehead was bruised, and he couldn't help but roar, this feeling was too uncomfortable, but he couldn't control it.

Now is the most critical time for cultivation, and the copper skin is about to be refined. As long as he persists, he will be able to complete the evolution from a beginner primordial martial artist to an intermediate primordial martial artist and refine a strong skin!

"Hold back, what is this pain!" Du Bixing gritted his teeth and insisted on the movement of the guiding technique. If he stops now, he will lose all his efforts, and the next breakthrough will definitely waste a lot of time and effort.

The metallic glow on Du Bixing's skin is getting stronger, and there are even signs of reflection in the sun. The ball girl has been testing his body to see how far it has evolved.

"It's coming!"

Du Bixing only felt that the burning and itching sensation on his skin disappeared completely in an instant, as if he was refreshed, and his body was full of strength.

"The evolution is complete!Master, you are now an intermediate-level primordial martial artist!" said the ball girl happily.

"Intermediate!" Du Bixing clenched his fists and gasped for breath, with a look of joy on his face.

From a junior primordial martial artist to an intermediate primordial martial artist, it only took him just one month! This was something he had never imagined before!

"The improvement of the "Fighting Chapter" is really fast, it deserves to be a top-level exercise!" Du Biqing couldn't help but admire.

"Of course!" the ball girl said in a smug tone, "The demon king who founded this technique back then also stood proudly in a short period of time!

"Hmm. Du Bixing nodded, and he asked, "Ball girl, what is my copper skin now, what is my defensive power?"

"Master, your copper skin has just been refined, and its defensive power is equivalent to A8-level metal materials. So normal attacks below A8 won't hurt you much. When the strength increases, the defense will continue to increase. ”

"In addition to your defense, your strength has increased to about 1,100 kilograms, and your speed has also increased slightly, which needs to be tested in real time. ”

"Very good!" Du Bixing is quite satisfied, now his strength, if he goes to take the martial arts exam again, it is estimated that he can get SSS+ results. The top student in this year's martial arts exam in Pak An Province is said to be SSS+!

However, in terms of strength, others are still much stronger than Du Bixing. Because of the champion of the martial arts exam, it is rumored that he is already a high-level original martial artist, which is very exaggerated!

And Du Bixing has just entered the intermediate original martial artist stage, and there are still many gaps.

"Go ahead and strive to reach the intermediate thirty percent evolution level before the start of Taizhou University!" Du Bixing once again embarked on his cultivation journey.

......

In the hunting area, in a certain jungle, a demon-patterned leopard was fighting with a teenager, and on the side, there was an intermediate primordial warrior who was sweeping for him.

"Pay attention to the arc of its claws!" Pang Yong instructed Zhang Zhigao, and Zhang Zhigao was nervously fighting the demon leopard with the strength of the original martial artist.

The strength of the demon leopard is stronger than Zhang Zhigao, but Zhang Zhigao relies on a well-equipped body to not fall behind. For example, his A9-level inner armor can protect the body. And the knife is an A11-level cold weapon, which can easily cut through the fur of the demon leopard.

There is also the protection of Pang Yong, an intermediate original martial artist with an evolution of 80%, this demon leopard is destined to become the prey of Zhang Zhigao's practice!

The demon leopard pounced on Zhang Zhigao, his paws slashed, Zhang Zhigao was a little panicked, and raised his knife to resist. The leopard's claws made several scratches on Zhang Zhigao's inner armor, and Zhang Zhigao slashed a deep scar on the demon-patterned leopard's body.

"Go on! Don't be stunned!" Pang Yong shouted.

Zhang Zhigao took a deep breath and took the initiative to attack the past. His talent is also good, but he doesn't have enough practical experience.

After a few more rounds, Zhang Zhigao finally caused serious injuries to the demon leopard, and the demon leopard wanted to escape, but was killed by Pang Yong with a punch.

"How do you feel?" Pang Yong asked.

"My body is so hot, I feel as if I can absorb the Force!" Zhang Zhigao said in surprise.

"Hmm. Pang Yong nodded, "Fighting can promote the body's absorption of gene-enhancing potions, especially life-and-death battles. If you cultivate now, you can definitely become a primordial martial artist!"

Zhang Zhigao nodded and immediately began to cultivate. And Pang Yong, clean up the battlefield for him.

An hour later, Zhang Zhigao stood up and said confidently: "I have already felt the force and become a primordial warrior!"

He punched the tree in front of him, and Gu Mu suddenly shook violently, and a deep fist mark appeared on the trunk! This is more than 700 kilograms of fist power! Compared with his martial arts exam, it has increased by 200 kilograms!

"Yes, you've improved a lot these days. This strength should be enough to enter Taizhou University!" Pang Yong exclaimed, "Let's go directly to the supply point, and then fly back and let you take the special recruitment exam!"

"Your dad will be happy to know the news. When you enter Taizhou University, he will also focus on cultivating you. Zhigao, practice hard!"

"Hmm!" Zhang Zhigao clenched his fists, his eyes full of confidence! Former martial artist, he has also reached it! With his talent and the cultivation resources at home, he will definitely be able to rise quickly!
