When Cai Chenzi first heard that Tian Xiaoding had gathered the five main materials for refining Huanyang Dan, he was so shocked that he almost pulled the beard off his chin.

He reaffirmed in disbelief and asked, "You mean, you have collected all the five main materials of the Yang Dan, the endless water of melting snow in June, the fire of the land under the sea, the snow in full bloom in the cold winter, the alchemy gold in the fire of Nirvana, and the acacia soil hanging in the sky for nine days?"

Xiao Ding nodded and said, "Yes, I have collected a copy of everything."

"Huh? How did you collect them all? Tell me about it, boy, where have you been in the past 20 years? What did you do?" Cai Chenzi was originally a very calm old Taoist priest, but now he has become not calm.

"Actually, my experience is not more than 20 years...... Xiao Ding had to recount his experience for more than half a year.

There are some things related to his Qiankun pot, so he can't describe them in detail, but only roughly describe the process.

Even so, Xiao Ding's legendary experience surprised and dumbfounded Cai Chenzi.

Tian Xiaoding's narration lasted for most of the afternoon.

In the end, he mentioned that his cultivation was not enough, and his alchemy level was limited, and he couldn't refine this Yang Pill on his own. Therefore, he went to the Immortal Medicine Gate and found it from the Immortal Medicine Gate......

It took a long time for the dust picker to come back to his senses. He is still immersed in the experience told by Xiao Ding.

If this were someone else, I don't know how many times I'd died. But when it was Xiao Ding's turn to be a little monk who had not yet built a foundation, he miraculously survived one danger after another, and he also gathered the five main materials for refining the Huanyang Pill by chance.

What Xiao Ding didn't mention was that not only did he gather the five main materials of Huanyang Dan in the process, but he also collected enough of those five-colored divine stones to upgrade the Qiankun Pot, and successfully upgraded the Qiankun Pot.

Hearing Xiao Ding talk about the purpose of this, Cai Chenzi also frowned, and he said to Xiao Ding slightly apologetically, "Tian Xiaoyou, to be honest, this Yang Pill is a super high-level pill, in fact, I have never refined it. If I let my master Changling real person refine it, then the success rate will be very high, but if it is refined by me, I will have no bottom in my heart."

Xiao Ding didn't have much confidence when he heard that Cai Chenzi was refining the Yang Dan, and he was also a little hesitant in his heart. However, Changling Zhenren has already retreated, and he knows about this. The last time Changling Zhenren retreated, it was a retreat for hundreds of years. He was already a monk in the condensation stage, and if the retreat time was short, it would definitely not be of much use to him. Therefore, there is no need to think about it, Xiao Ding knows that the retreat of the Changling real person this time will only be longer than the last time, and it will not be shorter than the last time.

In this way, the only person Xiao Ding knows who can refine the Yang Returning Pill is Cai Chenzi. If the dust can't be refined, then for others, it's even more impossible to refine.

Thinking of this, Xiao Ding was ruthless and said resolutely, "When I went to your sect before, I had already heard that the ancestor of your sect, Changling Zhenren, had closed the death pass. I'm afraid he won't be out of the customs if he doesn't have a hundred years. In this way, then only you can hope to refine the Yang Returning Pill. I'm now

Even if you ask someone else, you can't ask for anything. Therefore, I still hope that the seniors can work hard and help me, and I am grateful!" After speaking, Xiao Ding stood up and bowed to the ground in front of the dust.

Cai Chenzi hurriedly flicked his sleeves, released his spiritual power, helped Xiao Ding up, and said, "Since Tian Xiaoyou can trust the old decay, then the old decay will not refuse. It's just that we have to make it clear in advance, even if I refine this Huanyang Pill, the probability of success is only fifty percent. If I fail in alchemy, Tian Xiaoyou shouldn't blame the old decay!"

Xiao Ding only has one copy of the materials for refining the Huanyang Pill. He originally thought that this alchemy material could only succeed, not fail, so he deliberately went to the Immortal Medicine Gate. Even Lu Tianshuo, who had just broken through to the Jindan stage in Tianyao Village, he didn't trust it.

After the immortal medicine gate was in the air, Xiao Ding knew that Changling Zhenren couldn't count on it.

Then I had to pin my hope on the dust picker. But now Cai Chenzi says that he is only 50% sure, which means that the probability of success is only half, and the probability of the other half is failure.

If the alchemy fails, then it means that this only refining material will be burned and completely scrapped. And the hope of bringing the second girl back to life was completely shattered.

If you want to gather those five alchemy materials again, it will be even more difficult than ascending to the sky. Unless Xiao Ding can cultivate to the stage of transformation and reach the point where he can go to the heavens and the earth at will, maybe at that time, there is still hope to use his memory to go to the place where he found these five materials last time and collect them again.

However, even so, it is also difficult to come together, for example, among the five materials, "Alchemy Gold in Nirvana Fire" and "Snow in Bloom in Winter", where can they be so easy to come by?

Although Xiao Ding had planted the snow plant on the top of the snow peak in the Qiankun pot, after so many years in the world of the pot, it still bloomed as before, and did not retake root or bear fruit.

In other words, even if you want to plant this "snow in full bloom in winter", you will not be able to plant it. At least not yet.

With such a rare five kinds of materials, to be honest, Xiao Ding really didn't want to take them out to someone who was not sure about refining the Yang Returning Pill.

However, in the current situation, in addition to picking dust, does Xiaoding have any other choice?

Of course, Xiao Ding has no other choice. He couldn't find a second alchemist with the cultivation of Dust Picker, nor could he find someone else who could match the level of the second alchemy.

Therefore, even if Cai Chenzi clearly said to his face that there was only half the probability of success, Xiao Ding had to agree to it.

Otherwise, he would have to wait for hundreds of years, until Changling Zhenren came out, and he would have the opportunity to beg Changling Zhenren to make alchemy.

But Xiao Ding can't wait! Although if Changling Zhenren is willing to refin, then the success rate of alchemy will be greatly increased. However, Xiao Ding also couldn't know how long Changling Zhenren needed to retreat. Is it 100 years, or 200 years, 300 years?

This point, even if it is a dustman, he can't say it clearly. What's more, Xiao Ding simply didn't have the patience to wait for so many years.

Therefore, Xiao Ding can only refin

Dan handed over the materials to Caichenzi, and put all the bets on Caichenzi's body. Whether or not it can be refined into the Yang Returning Pill is a matter of one fell swoop.

So, Xiao Ding clenched his fists and said, "Don't hide it from the seniors, I only have one copy of this material. If I had made it myself, it would have been 100% unsuccessful. Now, apart from the dust harvesting seniors, I can't find a second alchemist who can be stronger than you. Therefore, I will give all this material to my seniors later. Seniors, don't worry. It's better to succeed, if it doesn't work, that's also God's will, and I don't blame my predecessors." After speaking, Xiao Ding still sighed softly.

Cai Chenzi nodded, and then said, "It's best to say it to your face. First of all, no matter what kind of friendship you and I have, after all, these materials of yours are too rare, and once they are scrapped, they will never be found again. Therefore, the old man does not dare to be careless!"

Xiao Ding clenched his fists again and said, "As long as the seniors do their best, whether they succeed or fail in the end, the final result can be accepted."

Cai Chenzi regained his former calm demeanor, touched his beard and said, "It's okay for me to help you refine the Huanyang Pill, but I have never practiced this pill before, and the first time I refine a super high-grade pill, with my alchemy level, I estimate that it will take at least half a month to complete the refining. So, I need to stay in retreat for at least half a month. And on the front line of Dakang City, there are several other cities that need me to supply them with some high-level healing pills, spiritual energy pills, and antidote pills......

"...... do you mean?" Xiao Ding couldn't help but ask.

"I mean, during my retreat, I'll leave the supply of pills to Dakang City and several other cities to you for the time being. With your alchemy level, refining some mid-to-high-level healing pills, aura pills, detoxification pills, etc., you shouldn't be able to

Questions, right?" Cai Chenzi said slowly.

Xiao Ding nodded in response, "No problem. I often refine these commonly used pills myself, so I am already familiar with them, and they can be regarded as the elixirs I am best at refining." Speaking of this, Xiao Ding suddenly remembered something, and asked, "It's just that if I refine the elixir to supply these cities, can the monks in these cities trust me?"

Cai Chenzi touched his beard and said, "Naturally, you can trust it. What is the elixir that others can't trust from the pills that came out of my house?"

Xiao Ding said humbly, "I'm afraid of ruining the reputation of my predecessors."

Cai Chenzi laughed and said, "You're not afraid that I will refine your elixir, so how can I worry about something that doesn't have a reputation? Hahaha!"

Xiao Ding also smiled and said, "Then it's decided, you retreat to help me refine the Returning Yang Pill, and I will help you supply the pill to several cities on the front line."

Cai Chenzi looked at the sky outside and saw that it was approaching evening, so he said to Xiao Ding, "Okay, even if we have confirmed the alchemy agreement between us, no one can go back. However, we still have to let go of the alchemy thing first, you are still in the Qi training period, I'm afraid you're already hungry, right? By the way, is your true cultivation really a period of Qi cultivation?"

Xiao Ding nodded and said, "It's true that I'm still in the Qi cultivation period, and I've tried to build a foundation many times, but I've been unsuccessful. By the way, I was just about to ask you, what is the reason why I can't build a successful foundation?"
