The sixth needle of the thirteen needles of the ghost gate was performed, and a thousand kinds of Chinese medicinal materials were recited, which has met Xu Zhendong's requirements for her.

Looking at her, Xu Zhendong was quite satisfied. He sat down in his chair and said, "during this period of time, as a teacher, I asked you to study medicine. Are you not satisfied?"

Yan Ruyu was silent for a while and lowered her head.

"To tell you the truth, it doesn't matter!" When Xu Zhendong saw that she was afraid to speak, he said again.

Yan Ruyu looked up at the master and said, "yes, at first I didn't understand why the master asked me to study medicine, but I saved a lot of people in the process of studying medicine. At the same time, I found that my patience and my temperament were well honed. I think that's why the master asked me to study medicine. I'd like to thank the master for letting me study medicine."

"Before you and Cao Yusheng, I had five apprentices, my big apprentice Luo Xiaoyu. Do you know that?" Xu Zhendong thought of Luo Xiaoyu, a little sad.

Only after the battle half a year ago and the disappearance of Luo Xiaoyu, he has never been born again, and he may have died.

"I know that the legend of elder martial brother Luo Xiaoyu has been circulating in the martial arts and Taoism circles, and we have heard a lot about him. He is the most legendary person besides his master."

When Yan Ruyu said this, her face was full of pride. It was her elder martial brother, and she was proud.

"Xiaoyu, when he studied medicine with me and took medicine into the path of cultivating immortals, his path of cultivation is very similar to mine. He is also the one with the best talent and the fastest progress. Now I want you to become the second Luo Xiaoyu and take medicine into the path. Only in this way can I practice my strongest sword technique: the sword formula of the taishangqingmujing."

To learn "Taishang Qingmu Jing", we must be able to integrate with plants and feel the existence of plants.

This is the main reason for her to study medicine.

Yan Ruyu knelt down on one knee and said, "thank you, master!"

"Get up, we don't have to kneel down." After that, Xu Zhendong jumped up and taught her the sword formula of the taishangqingmujing.

"This... The power of plants, the power of heaven and earth, the power of the road..." Yan Ruyu was shocked when she understood this skill.

Never thought of the power of nature, a plant looks so small, but contains such a huge power.

"Let's go. I have half a day to guide you. Later, if you can't find me, you can ask elder martial brother Bai Ninglong. Although he is not pure broken cultivation, he also integrates some skills to guide you. It's more than enough. One day, you will become the first level. Practice is the fastest way to make progress

Xu Zhendong took her to the back mountain and personally guided her to practice.

Some students saw it when they came out.

"When Yan Ruyu came back from studying medicine, her cultivation stagnated, and now she is far behind elder martial brother Ren Xun. It seems that it may not be a good thing for her to be a master."

"That's right. Just look at Cao Yusheng, lying on the back of the mountain every day, looking at a few grasses. Do you remember? Are you funny? Now he doesn't have any accomplishments. He's not as good as an ordinary man. I think he's possessed. "

"Well, two people who worship the Lord as their teacher are useless now. I don't want to worship the Lord as my teacher, hehe."

For these children's remarks, Xu Zhendong never cared.

Yan Ruyu looks coldly, but her mind is still a little immature. However, she believes that she can catch up with Ren Xun in the future.

Passing by Cao Yusheng's place of practice, I saw that his face was muddy and unkempt, much dirtier than when he didn't worship Lord Xu as his teacher.

Lying on the ground, staring at the seven different kinds of grass in front of me.

"Yusheng, how are you doing today?" Xu Zhendong asked.

Cao Yusheng's concentration was interrupted. He got up, looked at Shifu and said, "Shifu, are you back from medical school? Congratulations. "

"Thank you Yan Ruyu didn't understand his practice.

"Yusheng, show your younger martial sister your accomplishments." Xu Zhendong said slowly.

"Yes

Having said that, Cao Yusheng took out a bean from a small box on the side, put it on the ground and sat quietly for a while.

Yan Ruyu had no idea what he was doing.

Suddenly, I feel that some changes have taken place in the space. It's very subtle, but I can't tell where the changes are.

Cao Yusheng's hair has no wind, it seems that there is a demon wind passing by. He reaches out a hand and puts his palm on the beans.

The space between the palm and the bean is very different from the outside.

Yan Ruyu didn't feel it, but she always felt that the time for Cao Yusheng to show his strength was coming.

Xu Zhendong has been looking at him calmly.

Bang!

Beans germinate, in a moment, still growing up, with the speed visible to the naked eye.

Yan Ruyu was shocked.

How is this done?

Time?

Space?

This completely breaks the laws of nature and violates the laws of heaven and earth.

This bean sprout, which has just sprouted, has grown by 5mm and seems to have reached its limit.

Cao Yusheng breathed a little and looked pale. He turned to look at them and said, "master, I'm stupid. I can only do this now."

"That's good. Keep working hard!" Xu Zhendong said with admiration, "your younger martial sister is practicing at the waterfall over there. You can learn more from each other at ordinary times."

"Yes, master!" Cao Yusheng said respectfully.

"Ruyu, let's go."

They walked towards the waterfall inside.

"Shifu, what kind of skills does elder martial brother Cao practice? Why have I never heard of such skills?" Yan Ruyu asked suspiciously.

"Some things need special people to practice. Although his aptitude is not the best, his patience and tenacity are beyond the reach of ordinary people. After you compete with him, you will know that his martial arts are more domineering than the swordsmanship he gave you. "

Xu Zhendong said sincerely.

This is the "eight forms of Baitian" that he got from the ruins. Even in his early days as a golden elixir, he still can't understand it. We can imagine the degree of terror.

It contains a very complex mystery of heaven and earth, mysterious and mysterious.

Today, it is very good for Cao Yusheng to have such achievements, which shows that he has great talent in this field.

Hearing what master said, Yan Ruyu's eyes became dignified. She was so overbearing. It seems that she will have to work harder in the future.

When she came to the waterfall, Xu Zhendong demonstrated to her and told her some key points, observed her practice, pointed out her shortcomings and gave her correct guidance.

In half a day, she has mastered the skills, but it is far from the first level.

But Xu Zhendong is leaving.

"I have something important to do. You can practice here. Besides elder martial brother Bai Ninglong, you can also ask the holy doctor about this sword technique. When you come back to Beidou sect, you will come to guide you."

"Thank you, master!"

Xu Zhendong has gone. This time, his goal is to be the home of the Japanese people.

And Yan Ruyu looks at the back of her master, until she disappears.

Remembering master's teachings in my heart, I began to feel the power between heaven and earth, the existence of every plant, and imagine myself as a part of nature.
