The cultivation speed from the inside to the outside is at least twice as fast as the outside in, and of course the difficulty also increases exponentially.

Zhang Mu was not afraid of difficulties, he was only worried that the speed was too slow, after all, he was originally a high-grade primordial spirit body, if he could cultivate it early, he could stimulate the potential of his physical body and raise it to another level.

After a night, Zhang Mu established a silver seed in the dantian, which was one of the cores of the Yinfu body, and it was also a bridge connecting the physical power and the martial arts Zhengang.

Next, he needs to build energy points in the internal organs, spine, and limbs, split the transit place, and then connect the dots into a line, weave the thread into a network, and complete the energy circuit network.

He estimated that it would take about a month, and once it was completed, he would be able to get Yinfu in one fell swoop.

The next day, just as he was about to meditate on the cultivation of Yinfu's body, the tactical watch trembled, and the information that popped up made Zhang Mu have to leave.

In front of the pharmacist's building, as soon as Zhang Mu arrived, he saw Gao Mei waiting under the tree, walked over and said, "Do you want to start now?" ”

Gao Mei's delicate face had a strange smile: "Haven't you been idle lately?" Just enough to help me, my experiments will take at least a week. ”

Zhang Mu didn't know why, his scalp was numb, and he said speechlessly: "Don't laugh like this, okay, people feel that something bad is going to happen." ”

"Hehe, you feel good, you have to suffer a little bit in this experiment, you can refuse if you don't want to now."

Gao Mei blinked, as if she was not ready to force Zhang Wei.

"I said I would help you, how could I break my word." Zhang Mu shook his head, "You can arrange it, just tell me about the experiment casually, and just be mentally prepared." ”

"Talk as you go." Gao Mei smiled and glanced at Zhang Mu, if this man dared to break his promise.

The two walked into the pharmacist building, he had experienced the sturdiness of this building, and he could only destroy a few floors with all his might, so many pharmacists set up their laboratories in it.

As the youngest pharmacy grandmaster in Huaxia University, although Gao Mei is still a student, she is more capable than many teachers, and naturally has one of the best laboratories here.

On the ninth floor, Zhang Mu looked at the laboratory, which was more than twice as large as Nie Fan, and sighed: "If I had fought here, I guess I would have to go bankrupt." ”

Gao Mei glanced at her: "I'm embarrassed to say, if you hadn't been crazy at the beginning, how could you have lost so much money, six billion, enough for me to buy a state-of-the-art decomposition instrument, what a fool." ”

"Six billion for one instrument?" Zhang Mu was a little surprised.

"The whole school can only be two, do you think it's expensive?"

"I don't know much about your pharmacists." Zhang Mu shook his head, six billion can buy a mecha company, enough for a million people to live for a year, it can be seen that the price of various instruments of the pharmacist is expensive.

"Clothes for you." Gao Mei took out a set of clothes, "This is the isolation gown in the laboratory, let's change it." ”

Ticking, a woman came in from outside, and Zhang Mu said unexpectedly: "Lianxi, why are you here?" ”

Xiao Lianxi was stunned for a moment, she thought of what she did today, and showed a worried look.

"She's my latest assistant, is it a surprise?" Gao Mei walked over, "Senior Sister Xiao, you won't feel sorry for your little man, right?" ”

Xiao Lianxi's face turned red, and she lowered her eyebrows, "Brother Mu, this experiment is very dangerous. ”

"Junior sister, don't worry, your little man's body has reached the top spirit body, and it won't have too much impact." Gao Mei laughed.

"Really?" Xiao Lianxi looked at Zhang Mu, she was only an extraordinary third-order, and she didn't feel Zhang Mu's cultivation very clearly.

Zhang Mu shook his head, showing a comforting look: "No problem, you guys start." ”

He was telling the truth, the superior spirits, ordinary poisons are ineffective, but the physical body can withstand bullets, far beyond ordinary people.

Xiao Lianxi was relieved at this time, and opened a safe, which contained rows of red potions of the same model.

"This is a flesh enhancement elixir I developed, called Fire Rose, the grade has reached S level, and it has a great effect on the transcendent fifth-order grandmaster martial artist."

Gao Mei began to introduce, "All the tests in the early stage of this drug have been carried out, and now it is the last human experiment, I hope to find the most suitable concentration through you." ”

"Then I'm not a guinea pig." A black line appeared on Zhang Mu's face.

"It's about the same nature, but your flesh is much stronger than a guinea pig, and it may be impossible for others to test it." Gao Mei said seriously, at this time, she was completely in the state.

"Go ahead, I'll do whatever you say."

Zhang Mu didn't care, now his body, unless it is an SS-level potion, has not much effect at all, and naturally there is no psychological burden.

"First, install a detector to digitize the physical fitness, and then measure the degree of stimulation of the flesh by different concentrations of agents one by one."

Gao Mei signaled to Xiao Lianxi, Zhang Mu was equipped with a lot of sensors, and at the same time, a drop of his blood was also drawn for testing.

"My God, Zhang Mu, are you a pervert, the cell activity is so strong!"

Gao Mei looked at the data on the screen, her mouth opened wide in shock, and the flesh of the curtain was stronger than she expected.

She turned her head to look at Zhang Mu, "You know what? I once got a level 6 beast's heart, and its stats weren't as high as yours. ”

Xiao Lianxi showed a smug look, the more powerful the curtain, the happier she was.

"No, my look at your genetic sequence, is it the descendant of some high-level bloodline?"

Gao Mei's eyes lit up, as if she had found something that excited her, and hurriedly ran to the blood analyzer, and after seeing the data on it, she stared at a pair of Danfeng eyes and muttered:

"Impossible, you are actually a clone, the initial gene is very ordinary, how can you evolve such a powerful and excellent gene?"

Gao Mei frowned, and looked at Zhang Mu with some disbelief: "Generally, there is only one possibility in this situation, that is, to rely on your own cultivation and evolution, you can't be true, right?" ”

"Some luck has made the physical body far beyond the same level." Zhang Mu nodded and said lightly.

"Are you really from a civilian background?" Gao Mei was a little unconvinced.

"What do you think?" Zhang Mu smiled but did not speak.

Zhang Mu didn't say much, he looked at the blood analyzer curiously, he didn't expect that the current technology is so powerful, and he can analyze so much data with one instrument, and he can actually deduce the initial genes, the genes of his parents and his mother.

He was a little interested, clicked on the gene source catalog, and saw the source of his father's genes, and his pupils shrank.

"How did this gene come from a thousand years ago?" Zhang Mu held back his shock and asked.

"It's normal, thousands of years ago, the world changed greatly, and human beings were almost extinct, and many cloned genes were based on the gene pool of that era."

"Is that so......"

Zhang Mu smiled bitterly in his heart, he saw the information of his father's genes, and at a glance he could see that it was the genes of the physical body thousands of years ago!

"I didn't expect this body to be a descendant of my own body thousands of years ago, it's really amazing."
