Heavenly topic, because it is usually no one to challenge the problem, so in the medicine hall, only ten questions are prepared.

To some extent, the celestial theme in each hall, almost has been as a symbol of existence, has never been touched, and now Xiao Yu and Ye Han at the same time to challenge this field, the significance is very significant.

Not long after, the subject was sent.

This level of the topic, the general academicians have been unable to deal with, fortunately there is a Fang Minghe present, this day-level topic, directly sent to the hands of Fang Minghe.

After reading the title, Fang Minghe's eyebrows locked, for a long time, after a long time sighed, "Little friend, do you really want to challenge this topic?"Once you have seen the title, there is no room for remorse.”

"No matter what, old man, you just have to get out of the way."Xiao Yu did not hesitate, for him, the five holy monuments are necessary, it is impossible to give up.

“All right.”Fang Minghe helpless, he is now as a supervisor, can only remind, but do not have the right to leave Xiao Yu decision.

“This question, which was left by the previous head of the medicine hall, has been for decades, and although there have been challenges before, no one has ever answered correctly.”Fang Minghe said.

A word makes everyone nervous.

The previous owner?It is a master-level figure, and the subject left by such a person is certainly not simple, and for ordinary disciples, there is almost no possibility of completion.

“Come, take the medicine.”Fang Minghe ordered five academicians to get a prescription.

In the waiting of the people, the prescription was taken after a long time and handed it over to Fang Minghe.

From the outside, it is an old animal skin, and after Fang Minghe took over, he slowly said: "This method records a refining step called the fictitious Jindan, including the proportion of medication, refining steps, the required conditions, etc., in great detail."

“The fictitious Jindan?”Xiao Yu frowned, the name even if he had not heard, is it a certain drug that appeared after ten thousand years?

"Do not have to wonder, this Dan is the master of the office to create the drug, the master is a drug-domen, although only the realm of the master, but has created countless Qidan, this spirit of Jindan, but also condensed his life of energy."

Fang Minghe also looked a little sad, "However, this drug, in the end is not successful, no matter how hard he tries, always missed the line, this is also the biggest regret of the Lord."

Even if the Fang Ming crane did not say in detail, the people present could feel the strength of the master's medicine.

Self-created medicine, which is definitely a great feat in the drug, not amazing talent can not be done, like the current Fang Minghe, although it has been a near-day, but to create the drug, it is also very difficult, the master of the office is also a master, but can do, can be described as amazing.

"This topic left by the head of the office is his regret, this prescription is his life's work, but has not succeeded, this question is to pass, is to pass the test, is to the disciples to see the prescription, to solve the mystery of this prescription, correct where the prescription is wrong, led to the failure of this drug."The old man said the last word slowly.

For a moment, there was silence in the room.

Is that the topic of heaven?How is such a topic completed?

A master, the medicine that has been studied for a lifetime, has not been completed in the end, and actually asked a disciple to correct the wrong, which is simply difficult for the strong man!

No wonder the celestial question belongs to the taboo field, such a question does not say disciples, afraid that it is up and down the martial arts, no one can answer!

“Old man, can you show me the medicine?”Xiao Yu is calm a lot, as long as the day-level title is not to let him refine the three-pint medicine, everything is good to say.

The theory, in every way who can get to him?It seems that the martial arts also know that because of the limitations of cultivation, it is too unrealistic to ask a disciple to do such things as alchemy, so although the topic is difficult, it is not absolutely impossible for the disciples to complete.

“This is the old subject.”Ye Han listened to the topic, the eyebrows are also frowned, this question if he smoked, he did not dare to say that he must be able to complete.

However, seeing Xiao Yu's calm appearance, Ye Han couldn't help but be surprised, under such a topic, did Xiao Yu still think he could complete it?

If such problems can be solved, it is no longer a relationship of how much to score, for the whole Tianqingwu Academy, it has made a great contribution, which is equivalent to the achievement of the results of a master's lifelong research, and will have a great impact on the martial arts academy, on the medicine hall, and on the reincarnation hall.

After all, this means that Xiao Yu is equivalent to a master, and jointly created a new drug!

“It seems that the master of office is indeed an amazing person.”Xiao Yu looked at the prescription and quickly came to a conclusion.

This prescription records are very detailed, the proportion of medicinal materials, refining steps, remember very well, the people who created this recipe do have different ordinary people's minds, all kinds of ideas are very unique, otherwise they will not be appreciated by him.

“Little friend, how?You can see where the medication is wrong.”Although there was not much hope for Xiao Yu, Fang Minghe also asked casually at this time.

"Oh, in fact, this method is not far from success, there are indeed several places where there is a problem, as long as a little change, you can become Dan."Xiao Yu said very confidently.

With his eyes, he could see the ultimate intention of this square at a glance, and he could see the cause of the failure, which was too simple for him.

“Well, too!”Fang Minghe nodded, subconsciously thinking that Xiao Yu could not answer this question, after all, this question is no longer a simple question, but the huge problem that has plagued the entire Tianqingwu Academy for decades.

Suddenly, Fang Minghe stood still and said, “Little friend, what do you say?”Can you really see the problem with this medicine?”

Everyone was shocked, and Ye Han was stunned, and it seemed that some of them would be suspicious.

Although surprised by Xiao Yu's answer, but most people at this time are skeptical, no one can complete the problem in the martial arts, Xiao Yu a disciple, really can answer?

"Old Fang, can you please prepare the materials needed for this square, in addition, prepare some red sand, a soil root, and fire feathers."Xiao Yu did not explain, anyway, it must be proved in the end, it is better to act directly.

"This..." Fang Minghe hesitated, after all, I don't know if Xiao Yu can really do it.

However, if Xiao Yu really can do it, it is equivalent to making a great contribution to the medicine of Tianqingwu Hospital, and he thought about it, or he will order people to take these things back.

“Little friend, what next?”At this point, Fang Minghe also gradually began to choose to believe Xiao Yu, perhaps this young man, can really surprise him again.
