"Hmm..."Zhou Sheng thought about all the resources he had, which can increase the life span of the human body, and said: "Xu Fu, what you are asking for is nothing more than immortality, but before that, I want to tell you that there is no immortal medicine in the world that can make people immortal, at least, I don't know anything!" ”

"So, I'll give you two options."

Zhou Sheng gestured with two fingers and said: "One is the genetic optimization potion, you don't need to know what this term means, you just need to know that it can allow you to break through the lifespan limit of human beings themselves and obtain a lifespan of three hundred to four hundred years." ”

"With your physical condition, you should be able to gain a lifespan of about two hundred years, plus all your own Sacred Heart Determination and Phoenix Blood, how long you can extend your lifespan, I can't say, but eighteen hundred years or something, it's absolutely fine;"

"The other is the gene fission potion, its effect is to change the human body's genetic sequence, so that people can obtain strong vitality, restore fù power, even if someone has cut off their hands and feet, etc., they can slowly grow back, although it can't increase your lifespan much, but it can restore your body to a relatively young state!"

"In that case, it's hard to say how much life you can increase!"

"Alright, choose!"

Zhou Sheng put the choice in front of Xu Fu and let him choose!

These two things are the materials that Zhou Sheng copied into the system from the middle end of his teaching given to him by Pei Yuan Mingyu, one is a common genetic optimization agent in the fourth-level civilization, which itself is used to increase the average life expectancy of the people;

the other is the genetic medicine used in the army in the third-level scientific and technological civilization to increase the survival rate of soldiers;

Although in the era of galactic warfare, human life is not very valuable, after all, if the main gun of a ship is hit, I don't know how many people will die! But that's all in the dark, and that politician won't put these things on the surface, so there is the kind of gene fission potion that Zhou Sheng took out!

However, I don't know if it's because the big galaxy where the Hongming Empire is located is a mystical galaxy, and there is no way to open up a mystical genetic potion!

In the scientific and technological materials in the middle of the whole teaching, there are very few biochemical technologies about the human body, except for the genetically optimized drugs that increase life, such as biochemical drugs that can develop the potential of the human body, there are not many roots!

One is the biochemical medicine that Zhou Sheng chose for Xu Fu to increase the vitality of the human body and restore the strength;

Then there are the biochemical beast series of potions used in war; Planetary occupation against racial characteristics with extinction series of genetic viruses;

And potions such as those that can open up the human body's potential, open abilities, and superpowers are completely absent;

In this respect, there are no mysterious large galaxies, there are still good and bad!

"It can restore the body to a youthful state and prolong its life..."Hearing the choice given by Zhou Sheng, Xu Fu added his lips and said with difficulty: "My lord, if Xu Fu wants both, what do you need to give!" ”

"You want both, you're greedy enough!"

Zhou Sheng lay back on the rattan chair, thought for a while, and said, "Although I don't know how big the medicine garden in your mouth is, I think you are a smart person, so you shouldn't lie to me; ”

"Although your Sacred Heart Determination is useless in terms of cultivation, it has given me a lot of inspiration in terms of resurrection!"

Zhou Sheng calculated the value he brought to Zhou Sheng and the others to Xu Fu, and finally said, "I can give you both medicines." ”

"Thank you, Your Excellency!"

Seeing that Zhou Sheng, the divine envoy, actually agreed to his request, which was already quite Yu Yue, Xu Fu was overjoyed and said, "When will the Lord go to the Medicine Garden with Xu Fu?" ”

In fact, for Zhou Sheng, these things are all mass-produced things, and they are completely worthless!

But for Xu Fu, the two are things that cannot be equaled, one is useless to himself, and he has not seen it for more than two hundred years; One is what he has been seeking, although it can't achieve the effect that Xu Fu imagined!

"Now, it's okay anyway."

Zhou Sheng stood up, took out the No. 138 substance recombinant instrument stored in the soul space, operated a few times on the pop-up light screen projection, and began to reassemble the instrument for making two kinds of genetic drugs!

Material recombination is not only a single recombinant single-molecule substance, but can reorganize any substance whose structure has been resolved at the atomic level. Most of the reactions of the 138 material recombinant instrument are carried out in subspace, although only small substances can be made, but they are also relatively speaking;

For the No. 138 material recombinator, a diameter of less than five meters, or a cross-section of less than five meters, can be manufactured!

Manipulating the Rubik's Cube-shaped No. 138 Material Recombinant Instrument to assemble the two genetic agent synthesis instruments, Zhou Sheng waved his hand and summoned the two huge warship birds back with the spiritual connection he had established after putting Mo Yu and Bai Yu into the pet badge!

With a gust of wind, the corners of the clothes of the two of them made a strong sound, and the ink feather and the white feather fell not far from the two;

didn't see Zhou Sheng make any moves, so he ran to Mo Yu's back, and then asked Xu Fu to stand up;

Zhou Sheng patted Mo Yu's neck and said, "Slow down." ”

・・・

Let Mo Yu fly slowly, Zhou Sheng and Xu Fu sat cross-legged on Mo Yu's back, and then, Zhou Sheng called up the three-dimensional map of Shenzhou in the wrist-shaped brain, pointed to a small red dot in the projected huge three-dimensional map, and said, "This is where we are now..."

Then he asked Xu Fu, "Where are those two medicine gardens?" ”

Because the entire three-dimensional map is projected vertically, coupled with the red dot mark, Xu Fu can also recognize the map, his finger is crossed on the map with energy resistance, that is, the substance, to confirm the location, and then points to two places:

"My lord, this is it!"

"This is the medicine garden established by Xu Fu himself;" Zhou Sheng's current position is a little closer;

"This is the medicine garden that the empire built at the beginning

"Hmm." Zhou Sheng nodded, pulled two fingers on the map, enlarged the map, and said, "Can you confirm the specific location?" ”

Xu Fu recognized it and nodded!

After Xu Fu confirmed the target location, Zhou Sheng's fingers slid and drew a broken line between the three locations with the help of the wrist-shaped intelligent brain and the induction nerve, and the device nerve of the thinking activity; Then, after identifying the direction, Zhou Sheng patted Mo Yu's neck, stretched out his hand and pointed to the direction of the medicine garden established by Xu Fu personally, and said:

"Hurry up."

・・・

Although Zhou Sheng made Mo Yu fly faster, considering that Xu Fu might not have been able to withstand Mo Yu's speed, he also let Mo Yu's speed be maintained at about three hundred meters per second; And the medicine garden established by Xu Fu himself is not far from the location of Tianmen, and it is more than 200 miles from Los Angeles to the uninhabited area outside Tianmen, which is where Xu Fu's medicine garden is located!

Ten minutes later, near a deserted deep forest, Mo Yu and Bai Yu spread their wings and hovered in the air;

Xu Fu identified the large and small valleys and basins in the deep forest, and then pointed to a basin with a radius of more than ten miles, and said, "My lord, that is the valley where Xu Fu established the medicine garden in the first place!" ”

Pat the ink feather sitting under him and let it fall;

At the edge of the valley, Zhou Sheng jumped from the top of a big tree near the ground, waved his hand to let Mo Yu and the two of them play by themselves, Zhou Sheng, under the leadership of Xu Fu, walked towards the direction of Xu Fu's establishment of a medicine garden in the valley;

"Well, the aura in the air is getting richer!"

The more Xu Fu's footsteps approached the center of the valley, the more Zhou Sheng's sharp senses could perceive that the aura in the air had become thicker, and later, it had reached the point where the aura concentration had changed step by step, and the strange thing was that such a thick aura was almost unaware of it when it was at the edge of the valley!

I just think that the aura here is indeed a little thicker than the aura in the deep forest, but it's only a little bit!

Although this is not to spread out his spiritual sense to observe the surrounding environment, or Zhou Sheng's spiritual consciousness does not leave his own ten meters away on weekdays, because that always makes Zhou Sheng feel that he is not like an ordinary human being, so Zhou Sheng usually tries to restrain his spiritual sense!

And now, with curiosity in his heart, Zhou Sheng immediately probed forward with his huge spiritual sense, and included the entire place in the center of the valley within a radius of several miles into the observation of his spiritual sense, and then analyzed the situation!

At the same time, the observed situation is also fed into the system, and the data collected from several worlds is retrieved for matching or similar situations!

"I see."

By the time Zhou Sheng came to a conclusion, several minutes had passed, and Xu Fudu had already walked into the medicine garden with him, and then introduced Zhou Sheng to the various precious herbs in the medicine garden!

"What are you talking about, my lord?" Xu Fu, who was startled, asked Zhou Sheng!

"It's nothing, it's just the reason for the formation here!"

"Your Excellency knows?"

Xu Fu's expression was a little surprised, and he said: "Xu Fu found out that this was still when he stole the immortal medicine, when Emperor Qin learned that the immortal medicine he had refined for himself was eaten by Xu Fu, he sent masters, guards, and forbidden troops to chase and kill Xu Fu all over the world, and this is still the place where Xu Fu found out when he was panicked when he escaped!" ”

Zhou Sheng nodded and said, "Naturally formed, there are formations that gather aura, mask aura, and ecstasy effects; If you unconsciously approach here, you may enter the center of the valley; And it's like a purposeful search, but it's not easy to get in! ”

"No wonder the pursuers didn't find Xu Fu at the beginning!" Xu Fu had a feeling of sudden realization!

"But!" Zhou Sheng looked at the aura that almost gathered into a white mist in the valley, ethereal, and sighed: "I don't know how many years of aura it has gathered, it's really terrifying!" ”

As he spoke, 372 round beads appeared on Zhou Sheng's body, which were Zhou Sheng's 372 Jingyuan Dantian; As soon as more than 300 Jingyuan Dantian, which was only a little larger than a glass marble, surfaced outside Zhou Sheng's body, they began to spin drippingly, pulling the aura that almost formed a white mist to gather into the dantian!

More than 300 small beads were spinning and turning, and the huge aura they pulled was like a storm, directly triggering changes in the surrounding environment!

"This ...... This is...... What! Xu Fu looked at Zhou Sheng's body and suddenly had a lot of small beads, and stammered and asked!

"Collect Reiki Things!" Zhou Sheng replied angrily, took the Jingyuan dantian floating around him, crossed Xu Fu, and walked forward!

"This thing is ginseng...... This is Wuling flower...... This is jasper grass...... Ganoderma lucidum... Comfrey dew... Red Heart...... Crane saliva ......" While walking, Zhou Sheng used the information collected to identify the value of those medicinal herbs, although the names may be a little different, but according to the comparison of their various properties, the medicinal properties should be the same!
