With the arrival of Su Yang, many students have recognized Su Yang and know that he is the rookie king of this year, and they are all pointing at him, and there are many discussions in their words, some of them are envious, some are jealous, and some are cold-eyed.

Su Yang ignored all these various eyes, and found a seat in the valley to sit down, and Su Yang quietly waited for the arrival of his mentor.

After a while, a black shadow suddenly swept through the sky, landed on a stone platform in front of the valley, sat down cross-legged, looked at the students in front of him, and directly began today's lecture.

"Tequila grass, three leaves, emerald green, three flowers, light red, first-order spirit grass, its nature belongs to the liver, the taste is bitter and slightly cold......" a variety of spirit grass in the mouth of this mentor, each of which is very detailed, including its suitable refining elixir and quality, from simple to complex. At the end, he even explained some of his understanding of Dan Dao, and even some of these whimsical ideas touched Su Yang very much, and he couldn't help but fall into contemplation.

The students below also took out jade slips and burned all the things explained by the tutor, and some of the things they didn't understand would also be raised on the spot in front of the tutor.

This lecture lasted for nearly a day, and until the end of the lecture, there were still many students in contemplation, which showed that this teacher's Dan Dao attainments were definitely not low.

However, just as the mentor was about to leave, suddenly, a voice from him woke Su Yang up.

"You're Su Yang, right?" the tutor asked, looking at Su Yang.

"I—I'm Su Yang. Hearing the tutor's question, Su Yang immediately stood up and saluted respectfully.

"Well, you're good, here's your token, for you. After speaking, the tutor waved his hand directly, and a white light shot straight towards Su Yang.

As soon as he raised his hand to take the token, Su Yang took a closer look, and found that this token was no different from the one he got yesterday, except that the material changed from black iron to silver white, and he couldn't help asking, "May I ask the mentor, what is this token?"

"This silver medal is a symbol of your entry into the leaderboard, and it means that you have greater privileges in the academy, and you can get such a silver medal as long as you can enter the leaderboard, of course. If you are squeezed down by someone else on that day, then you also have to take it back, in addition, this token can also be challenged by others, as long as you face and lose, you also have to take back this token. The tutor explained. "Any questions?"

"No, thank you for your doubts. Su Yang arched his hand.

"Hmm. The mentor nodded, and then left the valley directly.

Leaving the valley, Su Yang played with the silver medal in one hand, while thinking about his cave mansion, his mind kept recalling some of the knowledge explained by the tutor today, and comparing it with what he understood.

"Wrong, it seems that I was wrong before, it is still necessary to have a place to systematically study alchemy, and this trip to the academy was not in vain. Thinking about it, Su Yang suddenly discovered many of his previous shortcomings, and also figured out where his gap was. Su Yang's previous Dan Dao knowledge was all obtained through some Dan recipes plus his own understanding, many things were taken for granted by himself, and there was no specific reason and systematic means, and it was definitely **** luck to be able to reach the point of a third-order Dan master.

"It seems that in the future, I will have to wait to listen to more lectures and visit the library. Thinking about this, Su Yang also had a goal for his future, and then thought about his cave and walked quickly.

Seeing that he was about to arrive at the cave, suddenly, three figures jumped out from the side and stopped directly in front of Su Yang.

"You are Su Yang?" The one at the head of the line, a man of medium stature, immediately opened his mouth to ask after seeing Su Yang coming, and the other two quickly surrounded Su Yang in the middle.

"I'm Su Yang, who are you?" Su Yang looked at the three people in front of him, he was sure that he didn't know the person in front of him.

"My name is Gao Xuan, and I came to challenge you!" Gao Xuan said to Su Yang with a solemn face.

Listening to Gao Xuan's words, Su Yang immediately smiled, as soon as the mentor finished talking about the challenge, someone immediately came, and couldn't help but say, "Your name is Gao Xuan?"

"That's right. ”

"Oh, I see. After Su Yang finished speaking, he directly pushed away the person in front of him and walked towards the cave without looking back.

Seeing Su Yang leave without looking back, Gao Xuan suddenly became anxious, and immediately ran to Su Yang to stop him again: "Didn't you hear you?

"I hear you. Su Yang continued walking.

"Then you're still leaving?" Gao Xuan said.

"What does it matter to me if you challenge me or not, I didn't promise you, get out of the way, don't get in the way, I still have something. Su Yang said and turned around and left again.

Gao Xuan was choked by Su Yang and almost spurted out a mouthful of blood, and yelled at Su Yang's back again: "Su Yang, you coward." ”

Shaking his head, Su Yang didn't pay attention to such a scolding at all, and went back to his cave mansion directly.

"Brother Gao, what should I do, he won't agree to the challenge?" Su Yang left, and one of Gao Xuan's companions asked Gao Xuan.

"Yes, Brother Gao, if he leaves like this, Zhu Shao will definitely not let us go. Another companion was also anxious.

"Don't worry, I'm thinking of a way, I don't believe that he has been staying in the cave and not coming out, as long as he comes out again, we are looking for him, I have my own way to get him to agree." Gao Xuan's face was also gloomy as water, and after thinking about it, Gao Xuan spoke.

After returning to the cave mansion, Su Yang immediately came to a small room in it, which he had specially sorted out for the purpose of being used as an alchemy room.

took out the medium-grade mortal medicine tripod issued by the academy, and Su Yang immediately started the alchemy, fortunately, he has recently obtained a lot of elixirs, there are a lot of them from the first to the third order, what Su Yang wants to refine is a third-order lower grade pill of Pei Yuan Dan, and Pei Yuan Dan has a miraculous effect on Su Yang's breakthrough through the late realm of foundation building.

"Fog grass, Dan Ling, hanging leaf flower...", one by one, the third-order spirit grass was constantly taken out, and the blazing Dan fire had been ignited in the medicine tripod, and one by one it was continuously thrown into the pill furnace, and after turning into ashes spiritual liquid, its ashes were also continuously removed from the medicine pot with the transformation of Su Yang's pill formula.

"Boom!" A moment later, with an explosion in the medicine pod, a puff of black smoke drifted out of it, and it was obvious that this first attempt had failed!

Su Yang cleaned up the residue in the medicine tripod with a wry smile on his face, and then prepared a medicinal herb again, and after a moment of pranayama, he waited until the spiritual power was full again, and began to refine the pill again.

A moment later, Su Yang's alchemy failed again!

After two successive failures, Su Yang had to stop alchemy and begin to think carefully about the reasons for his failure. "Hanging leaf flower, hanging leaf fruit, the medicinal properties are cold and hot, they are mutually restrictive, and if they are put together, it takes great mental power to succeed, but my spiritual power should be enough, right?" "That's?"

Thinking about it, Su Yang's eyes suddenly lit up, and he seemed to have grasped some kind of key, and quickly took out a hanging leaf flower and hanging leaf fruit again, and refined them separately. However, this time, Su Yang changed the previous order of placing the herbs, and directly put the two medicinal herbs together when it was the turn of the hanging leaf flower and fruit, and his spiritual power was fully expanded, carefully observing their changes.

After a while, along with the gradual melting of hanging leaves and fruits, the two medicinal liquids were suddenly intertwined, and a squeaky sound came, at the moment when the medicinal liquids were intertwined, Su Yang obviously felt that the medicinal properties were gradually decreasing, and its medicinal properties were also completely developing towards neutral, and in a moment, with a sound, the two medicinal liquids also turned into ashes again.

"Haha, I see, I see. Su Yang was not in a hurry, but laughed out loud, he finally figured out the key to this problem.

So, in the next, Su Yang once again gathered a set of spirit grasses, put them all into the medicine tripod, and launched a new round of alchemy again.

Sure enough, after understanding the key point of the problem, this round of Su Yang went surprisingly smoothly, and in less than half a pillar of incense, the five mellow white pills all fell into his hands along with the changes in Su Yang's pill formula.

"Three top grades, two medium grades. Not bad. Su Yangmei's self-absorption.

The alchemy has been carried out several times in a row, and at this time, Su Yang's spiritual power has also dried up, so that Su Yang has to stop, and after meditating to recover some spiritual power, Su Yang took a freshly refined Peiyuan Pill.

As soon as the pill entered it, it immediately turned into a clear stream and went straight down, turning into a powerful force in Su Yang's viscera, and with the help of this power, Su Yang also entered the cultivation.
