Li Yifan raised his right hand, a cluster of flames immediately emerged from his palm.

The fire of true Qi.

Different from the previous refining of ordinary pills, qiankunzaohua pills belong to six kinds of pills. The refining requirements are very high. The power of ordinary flame is not enough. At least the fire of real Qi is needed.

Of course, if it is the birth of some flames in heaven and earth, it is also possible.

However, those flames are also treasures that can not be met. It is extremely difficult to meet them. Even if they do, they must have strong strength to tame them.

He warmed the cauldron with the fire of true Qi. When the temperature reached the required level, Li Yifan took a few petals of ice lotus, a few whiskers of ginseng, a few leaves of tenglongcao, a small piece of chalcedony and a small piece of Ganoderma lucidum and sent them into the cauldron with true Qi.

Soon, he threw some auxiliary herbs into the cauldron.

Under the burning of the fire of true Qi, those medicinal materials quickly turned into liquid medicine and fused together.

The next thing to do is to wait for the liquid medicine to completely fuse, and then condense into the form of Dan medicine, so it's done.

Although it's the first time to refine such a high-grade pill, Li Yifan's mind has the countless experience of the Li family's ancestors. Under his careful operation, Qian Kun Zaohua pill was successfully refined at one time!

"Poof!"

He reached out to pick up the pills flying out of the cauldron, and started with a warm smell. Li Yifan sniffed the strong fragrance of pills in the air and nodded with satisfaction.

"Good! A success, almost 95% of the quality, although not absolutely perfect, but enough

He immediately threw the pill into his mouth, and the pill melted into his mouth, and the infinite power began to spread along the tendons and veins to every part of his body.

At the same time, Li Yifan compressed Qi and aura, refined medicine, and consolidated his foundation.

Although Qiankun Zaohua pill is a six grade pill, its power is very mild, and its continuous powerful force constantly refines his true Qi and body.

Soon, a pile of black mud appeared on the surface of his skin, just like the impurities produced when he first started practicing martial arts.

About two hours later, Li Yifan opened his eyes and felt the purer Qi and aura in his body, showing a very satisfied expression, "very good! The heaven and earth creation pill is really powerful. It works for all heavenly masters. Now my aura has almost expanded by a fifth, stronger and purer than before! There is no loophole in the foundation, perfect! "

This practice is not like the usual practice, nor is it like the previous breakthrough. It is full of hardships and great movement.

It's almost natural, very gentle and casual.

This is not only because of the mild medicinal power of Qian Kun Zao Hua Dan, but also because his foundation is already perfect and his strength is also very strong. On the surface, Qian Kun Zao Hua Dan seems to have no effect at all. If it is not for the mud on his body, he will think that his cultivation has failed.

"Hoo..." Li Yifan took a deep breath and said, "with my current strength, I will not be inferior to the Lingshi of shanggaojing!"

He has strengthened the foundation time after time, perfected the foundation time after time, and explored his own way of cultivation. His current strength can be said to be stronger than when he was still building the foundation.

When he didn't become a teacher of heaven, he could easily step up the level to challenge. In the foundation period, he could challenge the valley opening period.

Generally speaking, after arriving at the Heavenly Master, the gap of strength will be bigger and bigger, and the challenge will be more and more difficult.

When he first broke through the Heavenly Master, he could only challenge the primary spiritual master, that is, the early Yuan infant.

Although Gai Jiuyou used the secret technique to elevate his realm to the middle stage of Yuanying in the first battle of Qiankun tower at that time, in fact, his strength is not as good as the real middle stage of Yuanying, which is stronger than the later stage of Jindan, but weaker than the real early stage of Yuanying.

At that time, Li Yifan's strength was at this level.

Later, after he continued to pursue a strong foundation, he was promoted to challenge Gaojing Tianshi.

And now, Li Yifan has absolute confidence, even in the late Yuan baby, still can kill the enemy!

……

The next day, Li Yifan followed Zhai Shuo to the Medical University.

"Yifan, your admission procedures have been approved. I have arranged you in the master's class of traditional Chinese medicine department. Whether you go to class or not depends on your mood and time."

"Well, I see."

To read a master's degree, time will be much more free, of course, it also depends on self-consciousness.

With Li Yifan's current level of medical knowledge, of course, there is no need to come to class every day. As long as he can think of a good topic and do a good job in his graduation thesis, he can get a master's degree smoothly.

Then Zhai Shuo took him to meet with some leaders of the school, which is also convenient for him to have any unexpected situation in the future, or when he needs to submit some thesis materials, so as not to find no one.

The completion of the approval of admission procedures means that in the next time, Li Yifan must move his focus to the thesis a little bit.He must pass the defense of master's and doctoral theses in the next six months or even shorter time, and then rush back to Luzhou city.

Jiuxuanmen hasn't been cleaned up so far. Miao Xinxin and his three men have gone to miaojiang, but they haven't heard from each other so far.

There are also four things related to the ancient relics. Up to now, they have not been found completely. Except for the bianque needle, he does not know where the rest are.

In addition, he still doesn't know where the Kongling mountain is on the map of jiuzhuan immortal magic skill.

Many mysteries need to be solved by him, especially in the face of catastrophe. Tianji gate means a catastrophe. As a descendant of medical sage, he must solve these problems.

There is not much time left for him to be free.

In the next few days, Li Yifan was thinking about his master's thesis every day. What kind of topic should he choose.

At the beginning, he thought about some common questions, but soon rejected them.

If it is too common, it is not easy to reflect his level, and it is also easy to cause the examiners to question his level in the thesis defense.

Since we have to reply, we must show his level well.

Later, he thought that it should be regarded as actoretic hallucination, but he rejected this topic because although he took the main credit for the cure of actoretic hallucination, Cang Xuande and director Ouyang did more research on this topic.

Even if he is the first famous person, he basically did not participate in the whole project. If he wrote a professional paper, he would not be able to write it.

And if this subject is used again, it is a bit of opportunism.

"What is the right subject to use?" Li Yifan thought hard for almost a week before he finally came up with an excellent topic.

"By the way, in the medical books that master gave me, I have read them before. Are there some topics that are still hotly debated and often used for research? I should be able to find the right topic along this line of thinking. "

"A study on the symbiosis of heart, lung and kidney!"
