Ding Yi also rushed out. When he first saw Yu changsun, he was also shocked.

After more than a month's absence, his original handsome and bright appearance disappeared. He was covered with blood and ashes, which was very similar to Ding Yi who fled for several months.

"Brother Yu, what are you doing?" Ding Yi's mouth is full of fright.

Yu changsun chuckled: "something happened. Fortunately, there was no danger. Fortunately, I didn't live up to my life."

Then he hurriedly took Ding Yi into the room and said, "younger martial brother Ding, how are you doing?" Yu changsun is also very anxious. He hopes Ding Yi can become an intermediate alchemist soon.

Ding Yi said quietly: "it's a little later than expected. It may take half a month to a month, but don't worry, I'm sure."

Yu changsun nodded slightly, but he was not disappointed. Ding Yi's tone was firm and gave him confidence. He had been waiting for hundreds of years, and he still cared about the past one or two months.

Yu changsun spent more than 100 years in the later stage of Xuxian. He was anxious to be promoted to Tianxian, but now he doesn't care about these two months.

He took out a storage bag and gave it to Ding Yi. He talked about his experience in detail.

Ding Yi poured it out and found that he had bought 55 pieces of Xushen pills, and then four kinds of herbs, four of each.

These four kinds of herbs are the materials for making Tianxian Jianji pill. Each of them has four plants, which is a total of four.

This time, Yu changsun really tried his best. Ding Yi gave him 20000 Xianjing.

He bought 55 pieces of Xushen pills with 4000, which was much better than the market price. Because the other party was a big family, the man prepared 60 pieces in the middle and later stage of Xuxian's promotion. As a result, he succeeded with five pieces, and then sold the 55 pieces to Yu changsun.

Then he bought materials according to the prescription given by Ding Yi, but the Tianxian Zhuji pill is definitely the most popular one in the neighborhood. There are only two or three sects and five people who can refine it. No trading is allowed between sects and individuals. It's rare to see one in the black market with a sky high price of 150000. The materials are also extremely expensive. The rest of the eldest grandchildren have to vomit blood.

Yu changsun is also smart. When purchasing materials, he buys them separately. He only buys one kind of material for each person. That's all. It's very difficult to find.

A normal Tianxian building base pill is 100000. His materials are also expensive. There are 16000 yuan in the money Ding Yi gave him, which is not enough to buy four copies.

In the end, he posted three thousand fairy crystals himself and barely bought four materials.

If he can, he wants to buy another one. It doesn't matter if he spends some of his savings.

But on the one hand, there are not many materials for Tianxian jianjidan in the trading places outside. On the other hand, although he bought them separately, they still attract people's attention.

Bijing, the material of Tianxian building Jidan, is purchased by many sects. He bought it privately, so it's easy to be targeted.

So when he came out of the exchange, he found that he was caught up by three false immortals.

He spent more than 20000 immortal crystals in it. The three people were envious. They thought that Yu changsun was also a local tyrant. When he got out of the exchange, he blocked the way to kill people and wanted to rob him.

Yu changsun was surprised and angry. Fortunately, he was good at it. He killed his way and fled back to Qingling gate.

"Money can't be exposed, younger martial brother Ding. When you are outside in the future, you must remember that you should be careful even if you buy things. It's better to deal with people in private. When I buy something so valuable for the first time in a place where there is no one, I don't have much experience. Public trading makes people see my large amount of Xianjing, so it almost leads to death." Yu changsun's words prove that he treats Ding Yi as a friend now.

"It's also possible that the person you're dealing with will find someone to kill you." Speaking of this, Ding Yi is more experienced than him.

"Yes, yes, maybe." Yu changsun nodded repeatedly, suddenly realized that sometimes money is not a good thing, the outside world is really too dangerous.

"Younger martial brother Ding, are these four enough? Can we get a pill? " Yu changsun asked carefully.

Tianxian built one hundred thousand base pills. He bought four materials and used nineteen thousand, nearly twenty thousand.

Just one of them will bring Ben back.

However, in such alchemy schools as the Danding sect, they have three intermediate alchemists, the best level. They also make a small profit by making a pill out of three.

Yu changsun doesn't know Ding Yi's level, but Ding Yi is unknown and has just been promoted. It is estimated that he can get one dan out of four. Even if he is lucky, if he fails, he will run away in vain this time, and he can't afford to buy four more.

"Don't worry, it should be OK." In fact, Ding Yi is not sure. The higher the level of Dan, the lower the rate of Dan. However, he is very confident for the sake of the rest of his grandson.

Hearing the speech, Yu changsun was slightly relieved: "I will not disturb younger martial brother Ding. I will report to elder Wen first."

"Wait a minute." Ding Yi stopped him: "elder Wen doesn't know about this, does he?"

Yu changsun quickly looked back and sent a message to Ding Yi: "don't worry, I said I have something personal. I'll go down the mountain to buy something."

"Well, you can communicate with me about alchemy in the future. Don't say it." Ding Yi gives him a look.

Yu changsun nodded repeatedly, with an expression I understood.

Seeing Yu changsun go away satisfied, Ding Yi smiles. In the current situation, he is sure to pull Yu changsun to his side.

Everyone is selfish. If yu changsun wants to be promoted to Tianxian, he must ask Ding Yi. He may not dare to betray elder Wen, but he should be able to help Ding Yi in private.

After he left, Ding Yi took things into the room and began to calculate.

When he first smelted Buqi pill, he smelted four heats, and only one pill was produced in each furnace, so the rate of pill formation was very low.

Now I have only four pieces of materials for building the base pill. If I calculate according to the probability, all of them may fail, but none of them. Because the higher the grade of the base pill, the lower the success rate.

It's said that it takes dozens of heats or even hundreds of heats to produce one elixir of Wang pin's elixir level, which shows the difficulty.

What can we do? If all the four failed, Yu changsun would be very desperate and lose confidence in himself.

We must succeed.

But if you want to succeed, you can't rely on Yanlong tripod.

Ding Yi thought of what to use. He tried to see if he could use the first alchemy artifact in the fairyland, the Shilong King tripod, which is the most precious treasure of the heavenly fire Immortal King.

But it's a magic weapon. It's Wang pin's artifact. If the sacrifice comes out, it may immediately become immortal. Maybe even the heaven will find it. Then Ding Yi will die without a burial place.

So Ding Yi plans to make alchemy in Taichung.

But if he wants to enter the diamond platform, the diamond platform will appear outside, which is also very dangerous.

The quality of Jingangtai is not inferior to that of shilongwang tripod, and it may even be advanced. It's just that it's not an immortal tool, it's a treasure of Buddhism, so it's not so obvious in the fairyland.

But Ding Yi wants to put it in the room, and Wen zuisheng will surely find out.

So Ding Yi went out of the room and looked left and right. Suddenly his eyes lit up and he saw the mountain stream behind the house.

Before he jumped in to take a bath and found that it was a bit deep below.

Jinxian's initial idea was about 30 meters. He knew it when he escaped from Hong Ansheng's clutches.

Ding Yi thinks about it. He takes off his clothes and puts them on the side to let people know that he is preparing to take a bath.

Then with a plop, he jumped into the stream.

After jumping in, he was a little depressed. The mountain stream was deep, but it was only about ten to twenty meters. He could only keep swimming forward and down the river.

In his opinion, of course, the closer to the foot of the mountain, the deeper it will be.

I don't know how long this tour lasted. I suddenly felt my body sank. Finally, I was surprised to find a deep pit in front of me.

This place is deep enough.

Although the pit is not big, the size of a football, can not drill into a person, but as long as the King Kong platform can put in.

Ding Yi was overjoyed, and his mind swept away. The pit was a little deep. Thirty meters from the surface of the water was absolutely enough. Considering the Qingling gate and Jinxian middle stage, even fifty meters or 100 meters could be possible.

Here, whoosh, he stood on the pit, his figure flashed and entered the diamond platform.

The diamond platform sank slowly and fell all the way into the pit.

After sinking to the bottom, Ding Yi nodded with satisfaction. At this time, it was at least 150 meters away from the water. Even if there was any Guanghua released, Jinxian could not find it in the middle stage, unless they were also swimming here.

That's a coincidence.

After calming down, Ding Yi's mind began to enter the Dragon King Ding.

When he was in the world, Ding Yi didn't dare to tell him too much. When his mind met him, he would feel burned.

Wang Ding stopped quietly in the diamond platform, and there was no change on the surface.

"Wang Ding, Wang Ding, let me lend you alchemy --" Ding Yi's idea seems to be communicating with him and discussing.

All of a sudden, Wang Ding was suddenly bright, and the roar of the Dragon burst out. Ding Yi felt that his face was red, and the overwhelming fire seemed to cover him.

"Ah." Ding Yi is startled and thinks that he is going to be burned to ashes.
