Regarding Chen Feng's seclusion, the sixth-level alchemist of the Hua family had no idea, but the sixth-level alchemist of the Zhang family became more and more disdainful.

He did not believe that Chen Feng was able to understand the level of seclusion he needed in just three days. Chen Feng's announcement of seclusion was most likely just an illusion, and the purpose was to make outside monks think that he was a genius.

However, now that he had obtained the Zhang family's inherited jade slip, the Zhang family's alchemist was naturally not willing to stay in the Hua family any longer. He left the Hua family even with the inherited jade slip and went to report to Zhang Chao.

After listening to this person's report, Zhang Chao just smiled coldly, feeling a little down on Chen Feng in his heart.

"Although this person is a monster, he is still young and vigorous after all. I thought that this would make people think that he is a monster enough. However, I don't know that this retreat has exposed his lack of confidence." Dang Chao smiled coldly, and couldn't help but feel in his heart.

Be happy.

After all, Chen Feng is too evil and will put great pressure on the Zhang family. Now this is considered normal.

However, there was also someone in the Zhang family who was not happy about Chen Feng's retreat. This person was Zhang Minghao. He had originally made up his mind to kill Chen Feng, but when he heard that Chen Feng was in retreat, he became furious.

"Chen Feng, no matter how long you stay in seclusion, I will cut you into pieces!" This was Zhang Minghao's crazy cry, but no one could hear him except the old man in black robe standing aside.

…

At this moment, Chen Feng was still in Tiandan Immortal Mansion.

Before, he had calculated the right time to stop, handed the Zhang family's inheritance jade slip to the maid who was waiting outside, and then ordered the maid to declare to the outside world that he was going to retreat.

Then, he entered Tiandan Immortal Mansion again and entered a long retreat.

This time's understanding of the jade slips inherited by the Zhang family gave Chen Feng a lot of insights into the way of alchemy. These understandings are still superficial at present. If he wants to fully understand them and draw inferences from one example, Chen Feng needs to continue to understand them.

and testing.

He had summoned the Heavenly Alchemy Cauldron a long time ago, and in the Alchemy Cauldron, the purple flames of silence were burning loudly.

Chen Feng meditated hard, and every time he gained something, he would stop and verify it.

The flow of time in the Time Acceleration Formation is fifty times faster than in the outside world. In one day in the outside world, Chen Feng has been practicing in Tiandan Immortal Mansion for fifty days.

Spring turns to winter, flowers bloom and fall, and to the outside world, a full three years have passed.

In the past three years, Chen Feng has not left seclusion. In the past three years, he has stayed in the time acceleration formation for a full one hundred and fifty years.

For monks in the immortal world, one hundred and fifty years is really nothing. Those who are truly powerful can only retreat for tens of thousands of years. Even ordinary immortals can spend several years in retreat at a time.

A hundred years is considered normal. Some people even stay in seclusion for thousands of years in order to break through the realm.

On this day, Chen Feng suddenly woke up. Unknowingly, his hair had been dragged to the ground. He could no longer remember how many times he had his hair repaired in seclusion.

"Finally, I have fully integrated what I have gained this time!" A smile appeared on Chen Feng's face, and then he counted his fingers, and his face suddenly looked a little surprised: "They say that cultivation has no time, this sentence is really true! In the blink of an eye,

One hundred and fifty years have passed."

"In the past one hundred and fifty years, my alchemy level has skyrocketed. Now, I am not too tired to understand the inheritance of Demon King. On the contrary, the alchemy inheritance of Taiqing Daodetianzun is... It's still like chewing wax, and I can't understand most of the places." Chen Feng frowned and thought in his mind.

But soon, his brows widened, and he smiled self-deprecatingly: "Who is Taiqing Daode Tianzun? He is the ancestor of alchemy in the immortal world. If his inheritance can be understood so easily by me, then he He is also called the founder of alchemy."

The next moment, an ancient book fell into Chen Feng's hands. Its simple appearance exuded a heavy ancient aura.

"I have never had the chance to refine the last elixir on the first page of "Tiandan Notes". Now that my alchemy skills have made significant progress, it is time to try to refine this elixir." Chen Feng's face revealed. A wave of expectation.

Each of the elixirs recorded in the Tiandan Records was extremely precious, and it was of great help to Chen Feng. This time, Chen Feng's eyes once again focused on the third elixir above.

"Wan Lian Dan gathers the spiritual energy of all things in the world into one furnace. It can cleanse impurities, strengthen the body, increase cultivation, and strengthen spiritual consciousness. It can be said to be omnipotent!" This is a paragraph on the Tian Dan transcript, describing the purpose of Wan Lian Dan.

In Chen Feng's words, this Ten Thousand Alchemy Pills should not be something in this world. The efficacy of this medicine is simply unbelievable!

However, despite its powerful medicinal effect, the difficulty of refining the Wan Lian Dan is much greater than that of the previous elixirs. It is only now that Chen Feng is absolutely sure to refine this Wan Lian Dan.

"Anyway, one hundred and fifty years have passed, and it won't take more than a few years. Let's just refine the Zhiwan Alchemy today." With a thought in Chen Feng's mind, each elixir was filled with powerful aura. One after another, they leaped over and floated above Chen Feng's head.

"Thanks to the Demon King's Tomb team, I was able to collect the quantity of elixirs." Chen Feng looked at the elixirs flying in the sky and said to himself with emotion.

Wan Lian Dan! As the name suggests, it requires tens of thousands of elixirs to be brought together in one furnace, slowly burned with flames, and a specific method is used to fully integrate these ten thousand medicinal materials to achieve the potential of water and water fusion, and then produce qualitative changes, ultimately creating Wan Lian Dan. This Although the process sounds like a matter of just a few words, when done, it is enough to make most alchemists despair.

Generally, alchemy requires three or four main medicinal materials and dozens of other auxiliary medicinal materials, which are fully dissolved and combined into a pot of elixir. Even so, the alchemist still needs to spend a lot of energy, not to mention tens of thousands of medicinal materials at the same time. Smelting requires tens of thousands of times more energy than ordinary elixir refining.

As soon as the Wan Lian Dan furnace was started, Chen Feng felt a difficulty. Controlling the flame to smelt thousands of medicinal materials at the same time was too difficult. After all, the melting points of medicinal materials are different. With the same flame, the medicinal materials here may be burnt. The ones over there may not be dissolved yet. Only by controlling the temperature of each medicinal plant at the same time with your mind can you ensure that the potion of elixir will not fail.

However, it is not Chen Feng’s character to give up when faced with difficulties. The more challenging it is, the stronger Chen Feng’s reluctance to admit defeat becomes!

Under Chen Feng's careful control, this furnace of Ten Thousand Alchemy finally successfully started the first step, and each medicinal plant slowly melted. Due to Chen Feng's careful refining, the melting speed was very slow, but
Chapter completed!
