Because Li Anning's side has not broken through for a long time, Li Changsheng has always been very strict, with clear principles, and he does not dare to leak it.

In desperation, Yu Fei had no choice but to let Xiao Rong'er post a high reward on the alchemist forum: "100 billion yuan to buy a complete Zhuji Dan Dan Fang, if you are interested, please contact ...... quickly"

However, although the price was very high, however, they did not get any response.

Thinking that he was the nominal inheritance disciple of the old man of the Danhuang family after all, he tried to dial the old man's phone again, but as a result, he was not in the service area.

Yu Fei was unwilling, and called Elder Chen Kun again, only to learn that Emperor Dan had already retreated, and he no longer cared about everything in the outside world.

Yu Fei suddenly became a rootless wild child, called Tianyi.

He also knew that the Dan Fang of Zhuji Dan was the core secret of a sect, and he had not accepted the formal initiation ceremony and become a real disciple of the Tianji Sect now, so no one dared to tell him the Dan Fang easily.

Yu Fei, who was in a depressed mood, had to continue refining the Qi Refining Pill, anyway, this kind of pill is now very useful to everyone, even the stone turtle at the bottom of Xiliang Lake is also eating with relish.

Thinking of the stone turtle, Yu Fei's heart moved, and immediately in the dead of night, he quietly came to Xiliang Lake.

Subsequently, the communication of the ideas of one person and one turtle began.

"Old turtle, how long have you lived?" Yu Fei.

If you want to ask something, please use an honorific title. "Stone turtles.

"Turtle Gong, how long have you lived?" Yu Fei.

“...... You still call me Old Turtle, I feel respected...... I don't know how long it has lived, tens of thousands of years should have been there ...... "stone turtle."

"It's been so long, have you heard of Tsukidan's recipe?" asked Yu Fei.

"Of course I know the recipe for this low-level elixir!"

"Very good, you tell me quickly, when I learn, then you will have a good mouth again, don't you always say that the current pill, eating it has no effect, can the Tsukidan speed up your recovery." Yu Fei suppressed the joy in his heart and said bewildermently.

"What I know is the ancient recipe, some medicinal materials, may have been lost now, the specific formula, you may need to continue to explore it yourself. The stone turtle replied.

"No problem, I'm the most scientific researcher, as long as you give me the direction and basic prescription, I should be able to speculate. Yu Fei said.

After chatting with the stone turtle, Yu Fei generously threw three Qi Cultivation Pills to the other party.

If the formula of the stone turtle is truly effective, then it will save you a lot of money and countless troubles, as well as the favor you owe, which can be described as killing multiple birds with one stone.

The most important thing is that with this living fossil, if you have any difficulties and problems in the future, you can directly ask it for advice, which will save you a lot of worry.

As the saying goes, there is an old man in the family, if there is a treasure.

After accidentally getting the formula of Zhuji Dan from the stone turtle, for the sake of secrecy and scientific research, Yu Fei opened a separate alchemy room.

In their own room, Zhou Yanrong and Xie Wanqiu share a room, although they are not far from each other, but without Yu Fei's invitation, it is difficult for Xie Wanqiu to find out any key information.

To refine the Bone Strengthening Pill, you need a first-order demon pill, to refine the Qi Refining Pill, you need at least a second-order demon pill, and to refine the Zhuji Dan, you need at least a third-order demon pill.

With the increase in the demand for the level of the demon pill, the cost that Yu Fei needs to pay is getting bigger and bigger every time he tries and makes mistakes.

The refining cost of the Bone Strengthening Pill is about 100 million, the cost of the Qi Refining Pill is about 1 billion, and the cost of the Zhuji Pill has reached an astonishing 10 billion.

Not only is the price of the third-order demon pill needed every time extremely high, and it is difficult to find a price, but even the ordinary auxiliary medicinal materials in the pill are also expensive, which makes Yu Fei have a headache.

According to the old recipe provided by the stone turtle, Yu Fei quietly tried several times, but each time he declared a failure, and there was not even a bit of scum left, and he also had some pain.

The cost of a time is nearly 10 billion, and the amount and speed of this kind of loss are no different from those high rollers in the casino, they are all lucky.

If he continues to lose like this, even with his current family background, he will be a little unbearable.

This was still because he had accumulated some rare third- and fourth-order demon pills before, otherwise, the cost of purchasing high-level demon pills alone would have been enough to make him bankrupt.

It's no wonder that every powerful alchemist has a big sect as a background and to rely on, just relying on his own petty fights, the more he goes up, the more difficult it becomes.

The R&D cost is too high, and the success rate is almost zero, how can this be played?

Seeing that the high-level demon pills he had accumulated were getting fewer and fewer, Yu Fei was also a little impetuous.

"Could it be that in the future, you can only hunt demons everywhere, get a high-level demon pill, and then open the furnace to test it?" Yu Fei thought secretly.

With his current strength, he can barely sustain the war by fighting, but after all, it is too difficult, and it is still very dangerous.

The key problem is that in the previous net clearing operation, everyone was too violent, if he continued to stay in Jiangcheng, Yu Fei probably wouldn't have a chance to see the third-order and above demon pills again.

Since they would eat together every morning and evening, seeing Yu Fei's state, it was getting more and more wrong, Su Yue couldn't help but ask: "Boss, are you in any trouble, don't be afraid, there are us." ”

"Yes, if there is really something, please say it, let's all figure it out together, and we are all willing to believe you. Zhou Yanrong also said.

Hearing this, Yu Fei glanced up, his parents went to relatives, and today there are only Zhao Dalei and two beautiful women at home.

So, he sighed heavily and said: "The Dan Fang of Zhuji Dan is too difficult to crack, and the cost of trial and error each time is close to 10 billion, and if I continue to lose money like this, I may really go bankrupt." ”

"Is the demon pill too expensive, or is the auxiliary medicinal herb too expensive?" Zhou Yanrong asked.

"It's all expensive, but the most expensive is indeed the third-order demon pill, and the inventory in my hand is running out, and it can't withstand consumption at all. Yu Fei said with emotion.

"Brother Fei, if it's just a demon pill, I have a not-so-mature idea. Zhao Dalei said.

"What do you think, let's hear about it?" asked Yu Fei casually.

"We can set up a demon hunting team, all composed of masters of the Qi Cultivation Realm, and then, go to various places to participate in demon hunting operations, so that all the demon pills obtained will be our own. Zhao Dalei said.

Yu Fei's eyes lit up when he heard this, and he said: "That's a good idea, I don't have time to hunt demons everywhere, but you can indeed form a small team and go to other cities with demon beasts to cooperate with them." ”

"Since Brother Fei you approve, then leave this matter to me to be responsible, I have been idle every day recently, and I have been getting more dangerous and difficult places to temper myself. Zhao Dalei said with high morale.

Yu Fei hesitated for a few seconds and said: "It's up to you to take the lead, the weight is not enough, let Li Changsheng be responsible, you pick a few more good hands, assist from the side, with him coming forward, many city lords will give face." ”

"Understood, thank you Brother Fei for your trust, I'm afraid that Brother Changsheng won't agree. Zhao Dalei said worriedly.

"He eats and drinks in my house every day, and there is a special person to serve him, let him help do something, isn't it normal, rest assured, I came to tell him in person about this matter, I am not afraid that he will not agree." After Yu Fei finished speaking, he dialed the other party's phone.

"Brother Sheng, haven't you been bored lately?"

"It's a little boring, there are no decent monsters around Jiangcheng, and you don't have time to talk to me, it's not fun, it's boring!"

"That's right, I'm going to set up a professional demon hunting team for you, you are personally responsible, go to the surrounding major cities as foreign aid, all eating, drinking, and moving, I am responsible, you just need to concentrate on killing demons, and hand over the demon pill you get to me." Yu Fei said.

"Hehe, you want me to be a free thug for you, this benefit is not enough, and I am not stupid!" Li Changsheng replied.

"Of course these are not enough, when I refine the Tsukidan, I will be full!" Yu Fei directly threw out the big killing weapon.

Sure enough, hearing Yu Fei say this, Li Changsheng immediately responded: "Yes, I will set off the day after tomorrow, I have been idle lately, and I am only responsible for killing demons, not the life and death of the team members." ”

"You don't have to be responsible, as long as you live yourself. Yu Fei said casually.

"Deal!" Li Changsheng.

Yu Fei glanced at Zhao Dalei and said with a smile: "Okay, it's been negotiated, let's set off the day after tomorrow, remember, go out neatly and come back safely, the demon pill is important, and your life is also very important." Xiao Rong'er, go back and equip each of them with five Qi Cultivation Pills, ten Compound Pills, and ten Water Avoidance Pills, and in addition, give each person 20 million start-up funds, so that they can upgrade their equipment ...... by themselves."
