After entering the Xuandan Gate for four months, except for the first month, Yang Kai was refining the ten-turn heartless pill every day for the remaining three months. It can be said that the refining of this kind of heavenly pill has been perfect. Now even if he practices with his eyes closed, there will be no problem.

He even had the energy to quietly pay attention to the reactions of the sect leader and the two elders. The spiritual power over there was slightly surging, and the three of them were obviously communicating something in secret.

However, since I have been mentally prepared to expose some things, I have to take some effort to refine this time.

The white Dan Fire churned, Yang Kai's magic trick changed, and time passed.

After a few hours, the elixir was beaten out. Yang Kai slapped the elixir furnace, and a light sound immediately sounded in the furnace. At the same time, the rich elixir fragrance also spread.

Taking a light breath, Yang Kai took two steps back, clasped his fists and said, "Report to the master of the sect and the two elders, the disciples have finished refining, please check it!"

The three of them above stared at him in a daze, their faces full of unconcealed shock and incredible. They were the top leaders of the Xuandan Sect, and they were well-informed in their lives. They were used to all kinds of storms and waves. Even when they were fighting against the major alchemy forces before, they could not change their faces.

However, at this moment, the three of them didn't know what mood to face everything they saw.

Everything that happened before was beyond the perception of the three. If they hadn't seen it from the beginning and the end, they would have been afraid that the three of them would not have believed that there was such a bizarre thing in this world.

"How long?" Baili Yunsang was the first to come back to his senses, turned his head and looked at the elder and asked.

Wu Fenghua calculated silently and said in a narrow voice: "In less than three hours!"

Yu Boyang took a deep breath. Although he had expected it, he was still shocked when he heard this!

It took less than three hours to refine a furnace of ten-turn heartless pills! And it was also a Tiandan master who refines it. Even if they are old guys, it will take at least four or five hours. You should know that they are old elixir masters, and it will take at least six hours to get other Tiandan masters to go on the battlefield!

Such achievements have surpassed the Xuandan Sect... no, it is the refining record of the entire divine weapon world.

Baili Yunsang nodded slightly: "The time has been shortened by at least half, and now it depends on how it is pill." As he said this, he left in person, and the Great Elder and the Third Elder followed closely behind.

Within a few steps, the three of them stood in front of the alchemy furnace. The three of them all looked expectant and nervous, as if there was something crucial in the alchemy furnace.

"Open it." Baili Yunsang ordered.

Wu Fenghua responded, raised his hand and slapped the alchemy furnace. The cover of the furnace flew up, and the situation inside the furnace immediately came into view.

Yu Boyang immediately exclaimed: "Five pills are formed!" He reached out and sucked, grabbed the five pills in his hand, and carefully checked them, and his face became even more shocked: "Two top-grade pills, three middle-grade pills!"

Upon hearing this, Wu Fenghua quickly took the five pills from Yu Boyang, checked them all, and even put them in his fingernails to taste them. Then he said, "The effect of the medicine is fine."

Turning his head and looking at Yang Kai in shock, what he saw in front of him was simply amazing!

Baili Yunsang suppressed the excitement in his heart, tried to slow down his voice, looked at Yang Kai and asked, "How did it do it?"

Yang Kai clasped his fists and said, "Disciple has modified the elixir recipe for the ten-turn Wuxin Dan, and also used some other alchemy techniques."

Wu Fenghua nodded and said, "The pill recipe you used when you refine is indeed different from when you first started. Many processes have been streamlined, and some techniques are unique. I have never seen it before. Such improvements can indeed greatly shorten the time for alchemy and improve the quantity and quality of the pills! But... how did you think of doing these improvements?"

The ten-turn heartless pill recipe of Xuandan Gate was finally finalized after being improved by countless ancestors. Moreover, this is also the elixir of Tiandan, and only the spiritual elixir is qualified to improve it. Baili Yunsang also tried to repair this elixir many years ago, but unfortunately he made no achievements and wasted two years in vain. In the end, he had to give up.

Even Baili Yunsang could not do something, but was done by a Tiandan master who had only been in the first place for four months. Moreover, the improved elixir recipe is more than twice as good as the original one!

This is simply not something that humans can do.

"I don't know either!" Yang Kai replied with his fists.

"You don't know?" Yu Boyang glared and said, "How come you don't know? Didn't this pill recipe be improved by you?"

Yang Kai said: "Return to the third elder, the pill formula is indeed improved by the disciples, but for some reason, the disciples did improve so much. They just felt that it should be better to make those changes when refining the alchemy, so they did this."

These words made Baili Yunsang and the other two hear it inexplicably.

"This is the thing..." Yang Kai quickly took out the speech he had prepared before, "I was lucky enough to join the Xuandan Sect. When I first refine the Ten-Turn No Heart Pill, I used the original pill recipe. But one night afterwards, when the disciple seemed to be dreaming and woke up, I heard a strange sound in the dark. The sound was inexplicably unexplained and had no way to figure it out. The disciple didn't know what it was saying, but when he woke up and refined the Ten-Turn No Heart Pill, he instinctively made some changes. After that, every few days, the sound would sound, and each time it could make the disciple gain something. After accumulating for several months, the disciple improved the Ten-Turn No Heart Pill recipe to this extent, and also understood some strange alchemy techniques!"

This is an explanation that Yang Kai had already thought of. After all, his performance is indeed a bit bizarre and there is no reason for not being able to explain it.

However, the three of them looked shocked when they heard this.

Baili Yunsang said: "You said you heard a strange voice in the dark?"

"That's right!" Yang Kai nodded, "I suspect that it was taught to me by Master when he taught me to refine alchemy. However, I was too young at that time and didn't remember much, so I didn't understand Master's good intentions. Now, when refining alchemy, I may have touched some memories and remembered the things I had forgotten in the past. Those voices should be the sound of the master's earnest teaching in my memory."

Anyway, his false master was not in Xuandan Sect, so Yang Kai had already made up his mind to push everything to him.

Baili Yunsang shook his head slowly: "Although your master is also a genius, he cannot do this level no matter what. This matter should have nothing to do with him!"

Yang Kai was stunned: "Why did the sect leader make such a conclusion?"

If this had nothing to do with that false master, he wouldn't find any suitable reason.

Baili Yunsang didn't want to get involved on this topic, and waved his hand and said, "You don't need to ask too much. Anyway, this matter must have nothing to do with him. The strange voice you heard... This sect leader knows what it is."

Yang Kai was shocked at the time and thought to himself, how did you know, I don’t know what that is.

Yu Boyang said in a deep voice: "The master of the sect is suspicious..."

Baili Yunsang said: "There is no other possibility."

The great elder Wu Fenghua stroked his beard and nodded slightly: "This makes sense, but why is this happening?"

"God's will." Baili Yunsang sighed slightly, and after saying that, he looked at Yang Kai and asked, "Do you want to see the real person with that voice?"

"Master of the Sect!" Wu Fenghua and Yu Boyang were both shocked.

Baili Yunsang said: "He can even hear the sound of that thing, which means that he has a fate with that thing. If he lets him contact and contact, he may have more discoveries."

Wu Fenghua pondered for a while, nodded and said, "What the sect leader said is very much."

Yu Boyang looked at Yang Kai with a complicated look: "You guy is lucky, this is a blessing that many people will never be able to cultivate in their lifetimes."

Yang Kai was confused: "Sect Master, that voice... does it really exist?"

Baili Yunsang laughed and said, "You have heard it yourself, come and ask me?"

Yang Kai didn't know what to say. He originally wanted to push everything onto the false master, but he accidentally pulled out some amazing things. Now that things have come to this point, it is difficult to get rid of the tiger, so he can only nod and say, "About the arrangements of the sect leader!"

Baili Yunsang nodded with gratitude: "I'm not busy today. You can wait for a night to rest. I'll send someone to pick you up tomorrow. In addition, I have some things to ask you."

"Please tell me, Master."

Baili Yunsang said: "Where did the alchemy fire you used to refine elixirs come from?"

Yang Kai said: "I collected it from the Holy Fire Cave a few months ago. But I don't know what kind of alchemy fire this is. Does the sect leader know it?"

Baili Yunsang showed a look of silence. When he saw the white fire, he had some guesses. Now it was just a confirmation. He sorted out his thoughts and said, "Maybe it is the kind of alchemy fire I know, it's just a matter of no, and it needs to be verified."

As he said this, he ordered Yang Kai: "You can urge the elixir fire out."

When Yang Kai heard this, he immediately activated the Dan Fire, and the white flame floated in his palm, looking extremely gentle.

Baili Yunsang looked at the white fire, slowly stretched out his hand and approached Yang Kai. At the same time, a golden flame suddenly appeared on his hand, beating endlessly.

The golden flame was extremely pure and scorching. It was a spiritual level elixir fire at first glance. It was much higher than the white fire in Yang Kai's hand.

But as they approached each other, the golden elixir fire suddenly swayed, while the white fire in Yang Kai's hand did not move. This situation became more and more obvious as the distance narrowed.

Until a moment later, the golden flame shrank uncontrollably into a ball and retreated to Baili Yunsang's wrist, as if the golden elixir fire had spirituality and felt a huge danger.

Baili Yunsang took back his elixir fire and let out a gentle breath: "It's indeed it!"

Wu Fenghua and Yu Boyang both looked at Yang Kai with complicated expressions, obviously knowing what they had seen before.

"Check it!" Baili Yunsang ordered.
