"Buzz ......"

The holy sword was grabbed by Gongsun Xuanyuan in his hand, and after a burst of Weng sound, it stopped as if resigned to fate, no longer trembling, but lying quietly in the palm of his hand.

Obviously, Gongsun Xuanyuan has passed its test and has been recognized by it.

The holy sword has a spirit, choose the Lord!

Today, Gongsun Xuanyuan is its owner.

"Good sword!"

Xuanyuan carefully looked at the golden holy sword in his hand, only to feel that it was a match made in heaven with himself, he was immediately overjoyed and praised.

"Master, what is the name of the sword?"

Then, he held the holy sword in his hand and asked Yuan Shi, he liked this sword very much, and sure enough, none of the gifts given by the master were simple.

"The holy sword has no name, since it has chosen its master, it naturally follows the name of its master. Your name is Xuanyuan, then this sword is called 'Xuanyuan', what's the matter?" Yuan Shi smiled faintly and said.

"Xuanyuan? Xuanyuan Sword, it's really a good name! Fuxi has Fuxiqin, Shennong has Shennong Ding, and my sword is called Xuanyuan Sword!" His words completely exposed his heart, and he wanted to compare himself with the emperor and the emperor of the earth.

"Boom!"

The holy sword seemed to feel what his master was thinking, and suddenly, with the response, a huge golden sword pillar rose into the sky, tearing this piece of heaven and earth!

Yuan Shi saw it, and with a flick of his big sleeves, he instantly turned this huge golden sword pillar into nothingness, and the holy sword immediately became stable, not daring to tremble anymore.

"Uh......" Gongsun Xuanyuan turned off the fire in an instant, his face was stupid, and he looked at Yuan Shi with embarrassment.

After a long time, he regained his indifferent appearance and asked, "Master, why doesn't this sword have a scabbard?"

"Why does it have a scabbard?" asked Yuan Shi lightly.

"Huh?"

Gongsun Xuanyuan suddenly had nothing to say. Yes, why can't a sword have a scabbard? Who says that a sword must have a scabbard? However, before he could say anything more, he heard Yuan Shi's faint voice coming:

"This sword actually has a scabbard, and I've already demonstrated it, but you haven't noticed it. ”

There's a scabbard? How is this possible, why don't I see it. Master, are you sure you are not lying to your apprentice grandson? Gongsun Xuanyuan was speechless in his heart. Wait, like a lightning bolt crossed his mind, and suddenly something came to mind. Just now he seemed to see his master and ancestor pull out his sword from the void, could it be ......

Sure enough, he heard Yuan Shi's faint voice come again, proving his conjecture:

"Why does this sword need a scabbard to bind it, if there is a scabbard, then this void is its scabbard!"

Gongsun Xuanyuan suddenly felt in his heart, yes, the scabbard will only bind the spirit of the holy sword, and use the void as the scabbard, what a great atmosphere this is. He turned to Yuan Shi and thanked him:

"Thank you Master for the sword!"

"Alright, you go down the mountain. Yuan Shi instructed, "The world is at this moment when the wind and clouds are gathering, you must be careful, you take all the blessings and misfortunes by yourself, no wonder others, you go!"

"Yes, Master. Gongsun Xuanyuan respectfully bowed.

Then, he turned around and walked down the mountain without hesitation, a hundred years ago he went up the mountain, he was just a child, nothing, a hundred years later, he went down from here, but he had already learned a powerful skill, just waiting to go back to show his potential.

......

When Gongsun Xuanyuan left, another figure appeared on the mountain, it was Gongsun Xuanyuan's teacher, Guangchengzi!

"Teacher. ”

Guang Chengzi looked at the back of Gongsun Xuanyuan leaving, and said with emotion, "My disciple has had a rough life, and he likes to kill, I really don't know if it's good or bad?"

"That is his mission, as the human emperor of the three emperors, he has been destined since he was born, and he will fight all his life to unify the human tribes. However, he did have a bumpy life, and in his life, there were constant battles, and he would definitely encounter strong opponents, and when the time came, he would need the help of your senior brothers. The merits of the human emperor are not so easy to take. ”

"Oh?"

Guang Chengzi was surprised, and then nodded, as if he understood something. Just looking at Gongsun Xuanyuan in the distance, his eyes flickered, and he didn't know what he was thinking.

Yuan Shi glanced at him faintly, and then disappeared. In the same place, only Guangchengzi was left silent.

......

Shennong inherited the position of the co-master, and one hundred and fifty years later, he vigorously developed the production of grains, agriculture rose rapidly, and the human race basically solved the problem of food and clothing, and became strong.

However, it is precisely because the human race eats all kinds of grains and beasts with mortal bodies, and goes up to the mountains to pick wild fruits to satisfy their hunger, so they often have diseases and pains. Among them, I don't know how many people died in this disease, and for this, Shennong was distressed.

Shennong himself apprenticed to Xuandu, Xuandu is the descendant of the Taishang sage, and Taishang is the most proficient person in the flood wilderness, and Shennong naturally learned some of the art of pills. Although the pill can treat everyone's diseases, after all, the pill requires many precious medicinal materials, and it also needs to be proficient in the art of alchemy to refine it, and the quantity is still very small, it can only be used in a small range, not widely used.

To this end, Shennong has been improving various Dan prescriptions, simplifying them and being able to use a large number of common medicinal materials to solve the problem of human diseases. After a lot of experiments, the medicinal power precipitated in his ding was also increasing, and the alchemy speed and success rate increased greatly for a while.

But even so, it still can't solve the problem of the Terran's illness, because alchemy requires extremely high qualifications to learn, and among the Terrans, there are still very few people who can learn the art of alchemy.

This road is not good, it is very restrictive, and Shennong has to think of another way.

After thinking about it, he thought that since medicinal herbs can be used for alchemy, then just using medicinal herbs must also be effective in solving diseases?

Thinking of this possibility, his eyes suddenly lit up, and he felt that it was very possible. If he can find a way to directly consume the herbs, he can solve the disease, and he can solve the problem of a large part of the human race.

As soon as he thought of it, he directly consulted his teacher Xuandu, and Xuandu did not disappoint him, and gave him an elixir, which could allow people who had eaten it to test the medicinal properties or toxicity of plants and trees.

"Shennong, you must think about it, you may die because of this. Xuandu admonished.

"Teacher, I have decided, since I am the co-leader of the human race, I will solve the problems of the human race. Now that the Terrans are suffering from endless diseases, it is when I am needed, I have to stand up!" Shennong said with a firm face.

"Okay, since that's the case, I won't persuade you anymore, you can do it yourself!" Xuan Du looked at Shen Nong deeply and said.

The next day, Shennong gathered his people and announced his decision, after which he went on the road alone, left the tribe, and embarked on the road of tasting a hundred herbs.

This time, is dozens of spring and autumn, decades of time is fleeting, Shennong's footprints, all over the eastern land, on that land, deep mountains and old forests, often can see his figure.

He will personally try the toxicity and medicinal properties of various herbs, some of which are great tonics, while others are highly poisonous, and he has even been almost poisoned to death by the poison several times.

After various attempts, he also summed up a lot of experience, knowing which herbs can be eaten, what diseases can be solved, what poisons can be cured, and what things are highly poisonous and cannot be eaten, otherwise he will die.

This method of testing the drug by yourself bears huge consequences. Over time, the poisons of all kinds of plants and trees and the medicinal power of various herbs will accumulate in his body.

As time passed, Shennong would suffer more and more pain and disease, which was like a maggot on the tarsal bones, which was only attached to his body and could not be expelled. He spent every day in this boundless pain, but he still didn't give up.

He even created his own unique exercises according to the various medicinal powers and poisons in the body, which can absorb the medicinal power and poison to cultivate, and use medicine and poison as the magic skill, which is called "Medicine Divine Codex".
