Xuanyuan Dan is a miracle medicine for healing, and the effect on the meridian bones is more significant, but it only acts before the blood coagulation realm, and it can only be taken once in a lifetime.

Xuanyuan powder is even more unavoidable, it is on the way to refine Xuanyuan Dan, there is a mutation, there is a chance to appear, 10,000 Xuanyuan Dan, can appear once, it is a great creation!

But this kind of Xuanyuan powder, under the study of Emperor Xiaoyao Dan, there is an eighty percent probability that it can be refined, and the techniques and requirements are greatly reduced!

"Are these things expensive? Lian'er blinked and asked curiously.

When Qin Chen heard this, he hurriedly looked around, and couldn't help but gasp, these herbs actually had three pairs of herbs!

"Just this strain of blood ginseng, ordinary people can't use it up after eating and drinking for several lifetimes. Qin Chen took a deep breath, his eyes flickered slightly, and under Huan'er's surprise, he rolled up his sleeves, directly pocketed a pair of medicinal materials in front of him, trotted out of the secret room, and when he came back, the medicinal materials were gone, but there was a big iron pot in his hand.

"Brother Chen, what are you?" Huan'er was even more puzzled.

Qin Chen's face was mysterious, and he whispered in front of Huan'er, Huan'er heard this, his eyes became brighter and brighter, and finally cheered excitedly.

Time passed quietly, and early the next morning, a noisy voice came from outside the medicine hall, and an old man in a blue dan-robe, surrounded by everyone in the Qin family, proudly came to the medicine hall.

The old man's face was ruddy, there was no one in his eyes, he didn't care about the flattery of the people around him, he didn't even look at the medicine hall, and said, "This is the Qin family medicine hall?"

The implication of disparaging words is very obvious!

Qin Chen's grandfather, Qin Hong, was unhappy in his heart, but he didn't dare to show it, and hurriedly led the way, saying, "Please also invite Elder Wei into the secret room of the medicine hall." ”

Wei Lao put his hands behind his back, his expression became more and more proud, and when he approached the secret room, he suddenly frowned, his face showed displeasure, he flicked his sleeves, and shouted: "Qin Hong!"

Qin Hong's face was puzzled, and everyone around him didn't know why, but as the secret room was opened, everyone was stunned, and looked at the two people in the secret room blankly!

In an instant, the air seemed to freeze!

Everyone stared at each other, but they didn't expect that Qin Chen and Huan'er, who had been searching for them for more than ten days, were actually in the secret room, and Qin Chen's three uncles were even more gritted their teeth and secretly hated!

At this time, Qin Chen, with empty eyes, biting a wooden shovel in his mouth, squatted in front of a huge black pot, and the word delicious came from his mouth from time to time, like a fool.

His face was slightly pale, his breath was faint, as if he had not recovered from his injury, and the large iron pot in front of him was steaming, and a strange aroma emanated from it.

"Huh, why is there only one of the three herbs left?"

"No, it was still yesterday!"

"The fragrance coming from that black cauldron is ......"

Everyone gasped, all of them were dumbfounded, Qin Chen's three uncles sneered in their hearts, and secretly said that Qin Chen was doing it himself, and at this moment, Huan'er's eyes were slightly red, and she cried out.

"Master, you're back!" Huan'er suddenly rushed in front of Qin Hong, looking at Qin Chen's three uncles, with a look of horror flowing out.

She didn't need to explain, Qin Hong already understood, snorted, comforted Huan'er a few words, and then said apologetically to Wei Lao: "Let Wei Lao see and laugh." ”

Mo Lao was also stunned, and swallowed a mouthful of foam with difficulty, which showed the power of Qin Chen's cauldron stew, but Mo Lao was shocked for a while, then shook his head and said: "The old man who refining Xuanyuan Dan is only forty percent sure, so let's give it a try." ”

Waiting for Elder Wei to enter the secret room, Qin Hong hurriedly closed the stone door and began to wait anxiously, the Danshi alchemy forbade others to peek, as for Qin Chen, he was regarded as a fool and completely ignored.

Wei Lao turned his hand and took out a golden Dan furnace, the Dan furnace was three-legged and two-eared, the dragon and phoenix circled, it was extraordinary at a glance, he beckoned, took out a piece of red flame crystal, and was just about to start refining the Dan, his brows suddenly frowned, he looked at Qin Chen, and directly turned his back to the latter, blocking the Dan furnace.

One is to prevent Qin Chen from peeking, and the other is to be reluctant to look at Qin Chen more, especially the steaming big black cauldron, which is a shame for the Dan Master!

Just as he turned around, Qin Chen's stupid expression suddenly disappeared, his eyes flashed, the corners of his mouth turned up, and he said secretly: "It's exactly what I want!"

With a wave of his hand, he increased the flame, evaporated all the little water in the pot, revealing some stumps and leaves, rolled up his robe, and discarded it into the fire, and then carefully took out the processed medicinal herbs from his arms.

This medicinal herb was prepared by him in one night, and the cumbersome degree was beyond imagination!

Refining Xuanyuan powder, the most important thing is to control the change, a pill, from the refining to the end, as short as a few hours, as long as months or even years, the period is unpredictable, a detail is not handled well, the consequences are unimaginable.

And Xuanyuan powder, the key is to grasp the law of this change, so that nineteen Chinese medicinal materials, one thousand three hundred and sixty-five changes, develop in a specific direction.

Taking a deep breath, Qin Chen threw away his distracting thoughts, put the first medicinal herb Yin Yang Flower powder into the pot, and when the two powders were completely fused into an off-white color, he fused the third section of the seven herbs into it, and the strange aroma suddenly came to his face.

Qin Chen's spirit was unprecedentedly concentrated, slowly watching the changes in the pot's medicinal materials, and when the color turned purple, the cold blood lotus that had been prepared long ago turned into powder and fell down.

Blood Ginseng, Jade Meteorite Crystal......

Time passed quietly, Qin Chen seemed to have forgotten everything around him, completely immersed in alchemy, his perception of alchemy rose rapidly, if Wei Lao noticed it, he would be shocked, this strange state, Dan Master is hard to find in his life, he is called Danwu, and he has great attainments in alchemy!

"Bang!"

Suddenly, a sound of explosion Dan spread, the Dan furnace in front of Wei Lao trembled violently a few times, and a puff of black smoke drifted out, Wei Lao saw this and sighed secretly.

And Qin Chen also woke up from Danwu, his eyes froze, the heavenly demon bone in his hand turned into powder, and floated into the pot, he hurriedly covered the pot, carefully controlled the flame with one hand, and picked up the shovel with the other, pretending to be stupid.

At the same time, the door of the secret room was opened, and Qin Chen's grandfather, Qin Hong, looked at Wei Lao with an anxious face, and when he saw the latter put away the Dan furnace and shook his head slightly, his whole person took a few steps backwards, as if he was much older in an instant.

But just as Wei Lao was about to walk out of the secret room, his footsteps suddenly stopped, and he looked at Qin Chen with an incredible expression, or more precisely, at the big black cauldron!

"The scent...... How is that possible?"

Wei Lao's whole body trembled, his heart was shocked, and in the surprised eyes of everyone, he stepped in front of the big black cauldron, and opened the black cauldron with trembling palms.

The golden light overflowed, and the rich medicinal fragrance instantly filled the entire secret room, and everyone was in a state of spirit, not knowing what was happening.
