It wasn't that Qin Tianchen didn't want to tell Duanmu Invincible what kind of pill he wanted to refine, but he really didn't think about it for the time being.

If you really want to make a lot of money by taking out the Danfang, then you must choose the Danfang with a wider audience, and it must be the kind of profit that can be obtained from it.

This is a question worth pondering.

Qin Tianchen now temporarily set the Danfang he had chosen at three types.

One of them is the Boundary Breaking Pill, which can assist cultivators at the peak of the Yuan Infant to break through the realm of refining void, this kind of pill that can break through the realm, there will obviously be many people who are willing to spend a lot of money to buy it.

The second type is the Dragon Blood Pill, although this elixir cannot increase the cultivation of a cultivator, it can greatly strengthen the physical body of a cultivator, and even directly raise the physical body to a higher level.

For some body cultivators, this is tantamount to an elixir similar to an elixir.

The third one, called the Spiritual Pill, is an elixir that can assist cultivators in their cultivation, and after taking this elixir, if they cultivate again, they can directly double the speed of cultivation, which is suitable for any realm under the refining void.

These three elixirs, after each one is refined, can set off a storm in this world, but, considering the problem of raw materials and audience, Qin Tianchen must make a choice among them.

……

"Go buy these spirit grasses!"

After thinking for a while, Qin Tianchen directly wrote down the names of some spirit grasses, and then handed them to Duanmu Invincible.

"Buy these spirit grasses?"

"Didn't you say that the official organization of the Dan Dao Exchange Conference provided all the spirit grass consumption?"

"Why do we have to prepare our own spirit grass?"

Duanmu Invincible was a little puzzled, and then asked Qin Tianchen.

"Since we are creating Danfang, then many people will definitely remember some of the spirit grasses we use, just in case, so it's better to bring some of your own!"

Qin Tianchen said with a flickering look in his eyes.

Although Song Mingrui and the others couldn't believe that Qin Tianchen could really create the Danfang, after all, this was a good show they had planned.

But the other forces in the Imperial City would not think so, they would definitely send someone to monitor what spirit grass Qin Tianchen would use.

Although even if he knew which spirit herbs were used, but did not know the real refining technique, it was impossible to refine the elixir, but Qin Tianchen decided to be careful in order to prevent that kind of Dan Dao genius in this world.

The crape myrtle ancient star is so big, and it also has a very rich heaven and earth aura, in such a place where Zhong Tian Lingxiu is beautiful, the probability of genius being bred will naturally increase greatly.

So this kind of thing has to be guarded against.

The spirit grass that Qin Tianchen listed for Duanmu Invincible was actually not just a spirit grass for refining pills, but also mixed with some other spirit grasses for mixing up pearls.

He was already ready, refining the Boundary Breaking Pill, an elixir that can give people a chance to break through, must be able to stimulate the cultivator's madness even more.

If a cultivator who has been stuck at the peak of Yuanying all year round, after learning that the Boundary Breaking Pill can give them hope of breaking through, then this cultivator will definitely try his best to buy a Boundary Breaking Pill.

Even if you break the bank, it's a very worthwhile deal.

The other two pills obviously did not have such a crazy effect, which was also the reason why Qin Tianchen chose the Boundary Breaking Pill.

The spirit grass needed by the Boundary Breaking Pill is extremely rare in the ancient realm and the spirit realm, and even many of them have been extinct, but in the crape myrtle ancient star, which is rich in spiritual power in heaven and earth, those spirit grasses are not rare at all.

So...... As long as Qin Tianchen firmly grasped this Dan Fang in his own hands, then he could continuously obtain a steady stream of spirit stone resources to supply his cultivation.

It didn't take long for Duanmu Invincible to return to the inn with some spirit grass.

"Is anyone staring?"

"At least no less than five forces have been discovered, and they have been following me closely, and these spirit grasses we bought, it is estimated that they will be able to master them in an instant!"

Duanmu said with palpitations.

If Qin Tianchen hadn't thought about this in advance, then I am afraid that the spirit grass of the Sentence Breaking Pill would have been in their hands immediately.

Then let the alchemists under his influence study it.

"If they're staring, they're going to have to be busy. ”

Qin Tianchen showed a sneer, many of the spirit herbs he wrote about were conflicting medicinal effects, if a furnace of elixir was developed according to these spirit herbs, it would obviously be extremely difficult.

A few days passed in the blink of an eye.

Qin Tianchen used the efforts of the past few days to thoroughly study the pill system of Ziwei Ancient Star, and even some of the local pills in this world, as long as there were pills, he also tried to refine them.

The Dan Dao is actually the same in nature, but the Dan Fang is different, Qin Tianchen has completely adapted to the alchemy in the Ziwei Ancient Star.

"Two masters, today's Dan Dao exchange conference has begun, and the little one is here to welcome the two masters to participate in the exchange meeting!"

The receptionist at the reception, in order to make up for the mistakes he had made before, came directly over this time to invite Qin Tianchen and Duanmu Invincible, hoping to be forgiven.

Qin Tianchen didn't bother to bother with such a little person, so he walked out of the room directly and followed him to the place of the Dandao Exchange Conference.

"A total of 173 cities under the Great Wei Dynasty participated in the Dandao Exchange Conference, including both imperial cities and some unknown small cities. ”

"Each city has a Dan Dao representative, so there are a total of one hundred and seventy-three alchemists participating in this exchange conference!"

"Of course...... Those ordinary alchemists naturally can't compare to a master like Master Qin who created the Danfang by himself!"

The receptionist introduced the Dandao Exchange Conference, and at the same time, he didn't forget to pat Qin Tianchen's ass.

"This exchange conference, basically the famous figures in the imperial city will come to watch, and at the same time, for some alchemists, they will also give a very generous price to win over. ”

"At that time, Master Qin, I'm afraid he will immediately become a hot figure!"

Qin Tianchen basically ignored all the nonsense of the reception staff, and then watched the scene of the exchange conference by himself.

Because the Dandao Exchange Conference is held once every ten years, it is held in various places in turn, and each time the Dan King comes from which city, then the next Dan Dao Exchange Conference will be held in which city.
