"Ah" As the powerful energy surged, Duan Yun involuntarily let out a muffled snort. Some of the students outside had not yet fallen asleep, so he didn't dare to call out, and once he was discovered, it was conceivable what fate he would face.

Enduring the severe pain, Duan Yun's body was like cold sweat, he quickly took out a towel and stuffed it in his mouth, trying his best to channel his energy into the tree of mental power.

The violent energy impacted the entire tree, and the tree body also expanded sharply like a balloon, Duan Yun was surprised to find that while the small tree was thickening and growing, new branches kept sprouting from the trunk, and some branches actually had a few young leaves at the end, fluttering in the hurricane brought by the energy.

The strongest wave of impact was finally over, and Duan Yun breathed a sigh of relief. The remaining energy was no longer a big threat to him.

"Sixth-level martial squire!" Feeling this majestic internal force, Duan Yun was aware of the changes in his body. I'm afraid that no one's internal forces are stored in this way. Such an alternative way will certainly bring unbearable pain to ordinary people, but the benefits will definitely be much greater than ordinary people.

It's like that, and while there's no absolute fairness, if you want to be different, you have to do something different.

Even if he broke through to the sixth level of martial arts, Duan Yun knew the gap between himself and Yue Qing and cold-blooded.

He defeated Wang Hao in front, and the most important thing was to rely on teleportation to win. But if you are cold and cold-blooded, the situation is not so optimistic, after all, the other party has already known about this move, and should come up with a countermeasure. Especially if he is likely to be cold-blooded in the martial arts realm, even if he can use teleportation to dodge the opponent's attack, it will be extremely difficult to defeat the opponent.

In two months, it is very difficult to break through the realm again, and if you barely break through, the realm may be unstable. Then for now, you can only improve your martial arts. In the battle with Wang Hao, he already felt that the Ben Thunder Fist could no longer fully exert the potential of the Quadruple Vajra Body.

The Xuan-level mid-level boxing technique is just right for an ordinary four-level training body, but not for Duan Yun, the four-level vajra body should be able to support the Xuan-level high-level boxing technique.

However, Duan Yun also understood that Xuan-level high-level boxing skills were not cabbages on the street, and he couldn't even think about it without a large amount of spiritual jade. And in the vicinity of Shengtian Academy, ordinary low-grade pills can't be sold at all, and Zhu Yan Dan can barely sell some spirit jade, but if you want to buy Xuan-level high-level boxing skills, it's not so realistic.

In desperation, Duan Yun thought of a third-level pill recorded in the Medicine King Divine Dictionary - the Realm Breaking Pill. He didn't want to exile this elixir to the market, but now there was no better way.

Now that he had made up his mind, Duan Yun no longer hesitated. The only problem now is the source of the materials for this third-level Dan.

Although the students of the Alchemy Branch can exchange pills for medicinal materials, they are only limited to the same level. The pills he had refined before were all second-level pills, and it was impossible to change to third-level materials according to common sense.

Where can I get medicinal herbs?

Duan Yun's eyes rolled, and he remembered a person—the fat old man at the reception.

When he came to the Medicine Refining Branch, he realized that he had finally been fooled by the fat old man at the reception. The so-called academy task of the Alchemy Branch is actually to collect medicinal materials at the reception desk, and then refine enough pills to hand in.

This old fox, who made a painful appearance at the beginning, is too capable of acting. Duan Yun was indignant when he thought about it. This breath must be repaid with interest.........

The next day, Duan Yun got up early in the morning and walked towards the reception.

"Old fox, come out quickly, your little master Duan Yun is here. Far away, Duan Yun shouted at the top of his throat.

Hearing the words "Duan Yun", the fat old man was struck by lightning and stood up from the Taishi chair. The figure of the boy with a bad stomach appeared in front of him again.

"That kid came and said I ......wasn't there," the fat old man hurriedly greeted a few subordinates next to him, and wanted to pee.

"Old fox, why do you want to run ......away as soon as you meet" Duan Yun blocked the fat old man's way with a teleportation, and looked at him with a smile.

"Where's the old fox?" the fat old man pretended not to know anything, and in order to be more realistic, he pretended to look around.

"Sure enough, it's an old fox ......," Duan Yun scolded secretly.

Seeing Duan Yun staring at him intently, the fat old man coughed dryly in embarrassment. "Don't look at me like that, I'm not called an old fox, you should at least call me an old ......"

"Lao Yu, should we settle our accounts?" Duan Yun said unceremoniously.

"Ahem, I'm old, I don't remember well, I can't remember what I promised that day...... Why don't we change the conditions?" the fat old man's face did not change.

"Yes, it's just a busy time, and I forgot about it, so let's change the conditions. Duan Yun touched his nose and made a very cooperative appearance. "I want to get some herbs, I don't know what?"

"You said it earlier. Startled me, I thought you would open your mouth? nothing else, there are medicinal herbs!" Hearing Duan Yun say that he just wanted to get some medicinal herbs, the fat old man suddenly breathed a sigh of relief.

"This is the list ......" Duan Yun took out the list that had been prepared a long time ago and handed it to the fat old man.

The fat old man took the list and looked at it, and his face turned green.

"Can you change some other herbs?" he said with a sad face.

"No, I only need these, ten pairs of each. I won't bother you again. ”

"Kill me. It would be nice to be able to make up five pairs...... "The fat old man's intestines are about to turn green."

"Then eight pairs, no less" Duan Yun knew that this old man would definitely not bleed if he didn't cheat.

"Deal!" The fat old man hurriedly said for fear that Duan Yun would regret it.

"......" Duan Yun was speechless, still being tricked by this old man. However, there are eight pairs of medicinal herbs, which should be enough.

It didn't take long for the fat old man to prepare the materials that Duan Yun needed from the warehouse according to the list.

Duan Yun was quite surprised, originally he was just here to try his luck, but he didn't expect that such a scarce medicinal herb could be obtained smoothly.

In any case, everything is much easier with the herbs. Duan Yun didn't think much about it, and left the reception.

Looking at Duan Yun's back, an elusive smile appeared on the fat old man's face. And the deep meaning of it may only be known to him.

"If this kid is really as the bad old man said, it won't be in vain for all my efforts." He muttered to himself, lay back in the Taishi's chair, and hummed a little song.

Duan Yun was naturally unaware of all this. When he got back to his lodgings, he got busy.

The third-grade pill was something he had never refined before. After the accumulation of the previous four months, he felt that he had become much more proficient in all aspects of alchemy.

But as for whether he could practice the third-level elixir, Duan Yun still didn't know the bottom in his heart.
