After reading the documents on the stone wall, Xiang Bing suddenly turned his head to look at the green cow behind him, the green cow saw Xiang Bing staring at him and thought he was interfering with her, but Xiang Bing was still staring at it, but it was the green cow who suddenly charged at Xiang Bing.

As soon as Li Yun stepped into this place, he was targeted by a mysterious force, and the medicinal fragrance around him became more and more intense, even if it was not invaded by a hundred poisons, it was very troublesome to be surrounded by such a medicinal fragrance.

The deeper he went, Li Yun found that the colored blood on his body began to disappear, and after a while, all the colored blood disappeared, and the smell of medicine in the air did not gather here.

Li Yun, who was still confused, suddenly heard a voice coming from in front of him, and when he listened carefully, he found that it was the mournful screams and fighting sounds of the green cow.

He turned into a wind and disappeared in place, and when he arrived at the scene, Xiang Bing actually fell to the side injured, and Qingniu also fell injured.

After seeing Xiang Bing injured, Li Yun's whole body ignited with golden flames, and it was a metal warrior who attacked Xiang Bing, but Li Yun didn't care so much.

"Detect that the alien creature has an attack action, and start the program. After saying this, the metal warrior disappeared in place, and Li Yun also disappeared in place at the same time, and the sound of metal colliding was heard in the air from time to time.

No wonder Xiang Bing was injured, the iron pimple in front of him was far beyond normal people in terms of strength and flexibility, and the most important thing was that it was very rich in combat skills, and it could always dodge his killing moves at the most critical moments.

Seeing that Li Yun was actually able to fight with such a creature, there was both fear and excitement in the eyes of the fallen green cow.

Xiang Bing carefully observed the wound, she looked at the burned shoulder, thinking that when the green bull had just charged at her, she didn't have time to react before she was injured by a white light behind her, and the green bull crossed herself and charged towards the metal warrior.

After Xiang Bing saw the metal warrior's face clearly, she knew what was going on, and just as she was thinking, there were three loud noises in the air.

The metal warrior was slammed to the ground by Li Yun, standing in the huge pit Li Yun didn't dare to relax at all, his defense was far beyond his imagination.

Li Yun's attacks were continuous, and the Wind God Leg and Taizu Long Fist took turns to fight and couldn't break through his defenses.

Fortunately, he had practiced Vajra not bad magic skills, otherwise the reaction force alone would have made his hands tremble, but after eating so many attacks from himself, the metal warrior was not injured at all.

Just as he was about to use the Eighteen Palms of the Dragon Descending, there was a sound of footsteps in the distance, and Zhu Mengqi shouted at the metal warrior: "Stop!"

"Received the order," the metal warrior said respectfully as he broke away from the battle circle and came to Zhu Mengqi's side.

Since the other party had stopped for the time being, Li Yun came to Xiang Bing with a nervous face, and said distressed after seeing the bleeding shoulder: "Are you okay?"

"There's no problem, are you okay?" Xiang Bing asked a little relaxedly.

Zhu Mengqi trotted all the way to the two of them, she stepped forward to carefully check Xiang Bing's injuries, and then ran out and waited for her return, holding a lot of herbs in her hands.

"Although it is very simple, the herbs here are all rare and high-quality," Zhu Mengqi explained while helping Xiang Bing bandage.

On the contrary, Li Yun stared at the metal warrior, and his vigilance made Zhu Mengqi hurriedly explain: "He is not a bad person, he is a guardian." ”

Xiang Bing nodded and said, "It is indeed a guardian, listening to your tone, Miss Mengqi seems to have gotten some clues." ”

When Zhu Mengqi heard this, his face suddenly hesitated, and the reason was not purely instinctive reaction.

Xiang Bing didn't ask much questions, but explained to Li Yun: "The metal warrior in front of you is not a product of the earth star, he is an observer left by Shennong ten thousand years ago. ”

Li Yun showed a look of surprise when he heard this, and Zhu Mengqi also stammered, "Sister Bing, you know everything?"

"Isn't it written there, Pi Tong in the Eastern Han Dynasty wrote some truths there, whether it is classical Chinese or official script, I can understand it," Xiang Bing replied with a frown.

Seeing this, Li Yun stepped forward to help her, and he said distressedly: "Treat the injury first, and talk about these trivial matters later." ”

Zhu Mengqi sped up the movements in his hand, after all, there was still a green cow lying there.

After a while, Xiang Bing's wound treatment was completed, and Li Yun did not let go of his hand, but pulled Xiang Bing into his arms without saying a word.

Xiang Bing leaned on his chest, although he was shy, he didn't push Li Yun away, which made Zhu Mengqi behind him a little half-hearted.

"Don't you want to know the origin of Yaodu?" Xiang Bing asked softly.

Li Yun first smiled and said, "I don't want to know for the time being, but do you know the identity of this metal warrior?"

"Observer, the observer left behind by Shennong," Xiang Bing once again referred to the mythical Shennong.

Xiang Bing didn't care about Li Yun's eyes, she continued: "According to Pi Tong's explanation, the Shennong clan fell from the sky and happened to fall in a human tribe, and he fell from the sky and was surrounded by thunder, earth and fire, and people respected him as the Sun God and the Emperor of Yan!"

Li Yun was not stupid and asked, "Aliens?"

Xiang Bing shook his head: "Pi Tong didn't write, he only wrote that people came from outside the sky like the Heavenly Palace, and the rest is his opinion on the medicine capital, Pi Tong wrote Bian Que, and Hua Tuo has been here." ”

After Zhu Mengqi treated the wound of the green cow, he came to the two and continued: "Not only have I been here, but I have left a lot of things, Sister Xiang is right, the owner of the medicine capital is Shennong, and he is a visitor from outside the world. ”

Shennong is an interstellar explorer who was caught up in a plane crash while on a space voyage and finally accidentally came to the solar system to discover the planet Earth.

When he found out that this was a living planet, Shennong seemed very excited, after all, the spaceship needed to be repaired, and it was only when he landed that he found that it was in the most primitive period.

As soon as he landed, he was warned by the will of the earth star, and all his cultivation was sealed.

When he stepped out of the spaceship, he was cheered by countless people, and he was very happy to find that the natives here were about the same size as himself, even if he didn't have strong strength, he could withstand the danger with his physical fitness alone.

He didn't interfere too much, after all, there was the will of the Earth Star monitoring him, and once he interfered in the development of the human race, the Earth Star would directly kill him on the spot.

He had nothing to do but raise flowers, study some terrestrial plants, and collect materials to repair spaceships by the way, who knew that because he fell from the sky, people regarded him as the sun god, and they did whatever the gods did, so they had to grow food.

Not everything can be planted, the key is to eat indiscriminately, but something will happen, Shennong because of his special physique, he is not afraid of those who are poisonous and not poisonous, but the human race is different, eating indiscriminately will kill people.

Shennong saw that this was not good, if he died, he would definitely kill himself, the key was that he did not understand medicinal materials, in order to ensure that the sword on his head did not fall, he used the black technology in the spaceship to simulate the structure of the human race, and then began the legend of Shennong tasting a hundred herbs.

After listening to the story, Li Yun asked, "What does this have to do with medicine?"

Zhu Mengqi explained: "The medicine capital was originally just a wasteland, and Shennong's family used black technology to build a medicine garden that belonged to him because he was afraid of trouble, and planted all the herbs here for his own experiments. ”

"After a few decades, Shennong's family repaired the spaceship, for some reason had to leave the earth, he could only give up the study of the life of the earth, before leaving, this medicine garden hidden, leaving an observer to help him save the data, the key research problems can not be stopped like this, Shennong's left a test, so there is a way to open the medicine every once in a while to assess everyone, and those who pass can get a way to extend their life, so that they can continue to study the subject he left. ”

After hearing this, Li Yun asked, "Then these huge creatures outside are all research materials?"

Seeing the puzzled eyes of the two, he also told the two of them what he had seen, and after listening to his narration, Zhu Mengqi hurriedly nodded and said, "That's right, those are the five poisons." ”

How do you know that Li Yun pointed at Qingniu and said, "What about this?" Xiang Bing looked at Zhu Mengqi and found that the latter's face was full of confusion.

Zhu Mengqi explained: "I don't know very well, because many facilities in the medicine capital have collapsed, and the inheritance ended in the Ming Dynasty." ”

"And what are you looking for?life protender?".

"No, it's just a sycamore flower," Zhu Mengqi said with a smile.

Li Yun didn't pay attention to it, but Xiang Bing saw Zhu Mengqi's nervous expression, it seemed that this thing was very important to her, and Qingniu stood up and immediately let out an angry cry when he saw the metal warrior.
