Next, both sides made a heavenly oath to prevent both sides from repenting.

Of course, even if Fei Tianzhou didn't swear, he didn't dare to go back, otherwise he wouldn't want to see the sun tomorrow.

There is only the mark left by the old Dan Master on the Qiankun bag, and there is no mark of Fei Tianzhou. Since the old Danshi had fallen, when Fei Tianzhou said the method, Zhong Hou erased and opened the mark on the Qiankun bag very smoothly.

The wine gourd on Zhong Hou's body is also a Qiankun bag, and all the actions are naturally familiar.

When Zhong Hou's spiritual power penetrated into the internal space of the Qiankun bag, the whole person was stunned.

Although the internal space of the Qiankun bag is only about fifty cubic meters, and the capacity is only one-tenth of that of the wine gourd, the medicinal herbs and jade bottles containing the pills inside are piled up.

Don't look at the internal space of the wine gourd, but in fact, the place where it is really used is only a drop in the bucket. At the very least, the pile of medicinal herbs in front of him, whether it was the type or quantity, was more than ten times more than what Zhong Hou had scavenged in the core area of the Wind Volcano Forest before.

If the jade bottle containing the pill was all full, it would be even more amazing.

In addition, various classics are also layered, and the total number is more than the Situ family's collection.

Zhong Hou roughly scanned it with his spiritual power, and found that most of these classics were actually related to 'Dan'.

Among them, the basic category includes the types and medicinal properties of medicinal materials, the matching method of medicinal materials and the changes in medicinal properties after matching, the types and functions of Dan medicines, Dan Fang, the classification and identification of Dan furnaces, the use of Dan furnaces, the basic operation of flames, the basic process of alchemy, etc.

The advanced category includes the skills of fire control, the relationship between the flame and the Dan furnace, the requirements of different types of pills for the flame, the techniques and techniques of alchemy, the order of placing various medicinal materials in the alchemy process, the heat and time, the various precautions for alchemy, the common problems and treatment methods of alchemy, etc.

Just a cursory look at all the classics, without more than ten years of hard work, you can't finish reading it at all, let alone mastering it, let alone practicing it.

Moreover, it is usually easy to learn theoretical knowledge, but it is not an overnight thing to do in practice. A Dan master often spends his whole life in the success and failure of alchemy, and he has been constantly practicing all his life.

It's no wonder that the comprehensive strength of Dan Shi is generally not strong, and they waste their time and energy on Dan Dao, so it's no wonder that they can be strong.

Only a small part of the rest is cultivation exercises and martial arts.

Since you must be a fire-attribute star to become a Dan Master, the exercises and martial arts here are all fire-attributed.

It is worthy of the inheritance of the Danshi, and it is really worthy of the name.

Seeing this, Zhong Hou thought of two questions.

First, if Fei Tianzhou wasn't a fire attribute star, the inheritance of the old Dan Master would probably have nothing to do with him.

Second, there must have been Dan masters in the ancient period, but the cultivators in the ancient period cultivated the Origin Star Power. From this, it can be inferred that the origin star power must be used for alchemy, but whether it is directly alchemized or converted into fire attribute star power and then alchemized remains to be verified.

Zhu Gangguan said before that the origin star power must be able to be transformed into eleven different star powers, but spending time and energy to specialize in it is simply a matter of abandoning the basics.

Now it seems that the statement of pig Gangguan is not necessarily all right.

At the very least, it is certain that the cultivators of the ancient period were not just superficial in their research on xenostar power. From the path of alchemy alone, many things can be reflected.

Therefore, Zhong Hou decided that if he had the opportunity, he would still conduct some research on the eleven xenomorph star powers.

That's for later.

Among the large number of medicinal herbs, jade bottles, and classics, there are three very conspicuous large tripods, and a small number of star weapons of unknown grade.

The three tripods are all three-legged, all of them are one person high, but the shape and size and the patterns depicted on the tripod body are different.

The faint fiery red color, as well as the vicissitudes of life that emanates from it, reveal the historical charm of the three Dading.

Zhong Hou didn't look closely, and continued to sweep his spiritual power to other places.

After sweeping around, he finally fixed his eyes on the pile of classics related to Danfang.

Zhong Hou estimated that Danfang was most likely hidden in these classics.

However, Zhong Hou is very experienced in this area, and it is the most time-consuming to look through books to find information.

In order to save time, he directly withdrew from the Qiankun bag and said everything he saw to see if Fei Tianzhou had some simple and quick solutions.

Sure enough, Fei Tianzhou didn't even think about it, and directly told the specific location of the Nirvana Dan Fang.

For the sake of safety and confidentiality, Fei Tianzhou had memorized all the notes of the old Dan master word for word, and the corpse had been destroyed. Dan Fang's position is even more familiar, and there is no need to think about it at all.

With specific coordinates, it's much easier to find.

Zhong Hou once again infiltrated his spiritual power, and in just a few breaths, a classic book called "Ancient and Modern Rebellion Against the Sky and Changing Lives Dan Fang Lu" appeared in front of the two of them.

"Ancient and Modern Records of Dan Fang Recipe for Changing Lives Against the Heavens" is indeed worthy of this name, and the Dan recipes recorded above, as long as they are successfully refined into Dan, their effects can indeed change their lives against the sky.

For example, the elixir that can cure all the poisons in the world.

For example, as long as a person dies for more than twelve hours, the elixir that can be resurrected.

For example, all the bones in the body are shattered, or all the meridians in the body are broken, or the dantian is completely broken, or the muscles and skin are all rotten, and the pill can be reshaped.

For example, even if you have broken hands and feet, blind eyes, and a missing nose and ears, you can be reborn as an elixir.

Wait a minute...

This kind of elixir is said to be a change of life against the sky, and it is by no means blown.

However, these pills all have one thing in common, that is, the difficulty of refining is very high, and the probability of becoming a pill is very low.

Moreover, most of the Dan prescriptions are incomplete.

On the classics, there is a large and detailed introduction to the history of each Dan prescription and the effect of Cheng Dan, as for the medicinal materials required for refining, either this or that is missing.

The most outrageous Dan prescription only recorded a medicinal herb on it. The rest of the required medicinal materials, the refining process, etc., only the word 'unknown' remained.

Or, a certain medicinal material has become extinct, even if the Danfang is complete, it is impossible to gather all the medicinal materials in the Danfang.

These Dan prescriptions, which are missing or impossible to achieve, are written out for reading only and have no practical effect at all.

This discovery made Zhong Hou and Fei Tianzhou feel a chill in their hearts, especially Fei Tianzhou, his face turned blue on the spot, and his hands turning the book began to tremble.

They were afraid that if the pill of Nirvana was also only for reading, then their hopes would be lost.

With apprehension, they finally turned the page that recorded the Nirvana Dandanfang.

After reading it carefully, their hearts were relieved on the spot.

Fei Tianzhou breathed a sigh of relief.

The Nirvana Dan Formula is complete, and all the medicinal herbs mentioned above are available.

The only thing the two of them were worried about was that because they didn't know how many years had elapsed between the death of the old Dan master and now, whether the medicinal materials that the other party could find back then had become extinct by now.

This is something that the two simply could not have predicted.

After all, there are countless cultivators in the Star Continent, and the amount of pills consumed every day is immeasurable, and as a raw material for alchemy, the consumption of medicinal materials is even more astronomical. The medicinal herbs that still exist today may become extinct tomorrow.
