After the clicking sound, Zhang Yuwei turned his right arm into a body of water, because the medicinal materials on the earth were too fragile, and he directly used the Holy Dao to kill Tianyan to refine the pill, which was easy to damage the medicinal materials, so Zhang Yuwei first wrapped a light layer of water film around the periphery of the medicinal materials, and let the Holy Dao Kill Tianyan refine the medicinal materials by calcining the water film.

"Although the presence or absence of the power of the wood element is extremely important for an alchemist, alchemy does not only rely on the power of the wood element, but also needs the power of other elements to assist."

Zhang Yuwei's left hand turned into a sword finger, and a golden flame shot out from the Dan furnace, enveloping the medicinal materials in the water film, and then he clenched his left hand into a fist, and the Holy Dao Killing Tianyan began to continuously calcinate the water film, and the medicinal materials slowly decomposed under the high heat and merged into the water film.

"An elixir, in addition to its own medicinal properties, also needs a lot of attention, including taking it, how to take it better, is also a part of alchemy"

Qin Xiyan was holding a small notebook, she stared at Zhang Yuwei carefully, her eyes didn't dare to blink, only to see Zhang Yuwei swing his left hand, and the Holy Dao Killing Tianyan withdrew into the flame pill furnace, at this time, there was not a trace of medicinal materials in the water film, although some of the water film was no longer the original sky blue, but not even a trace of residue could be seen.

Seeing that the water film had completely absorbed the medicinal materials, Zhang Yuwei also smiled slightly, he knew that the first step, the quenching of the medicinal materials had basically been completed, and as soon as his right arm was raised, Zhang Yuwei released his Dan energy, wrapped the water film with Dan energy, and then he controlled the water film to enter the Dan furnace, and at the same time, his left hand violently exerted force and began to heat up the Dan furnace.

The sound of "empty" came from the Dan furnace, it sounded like the sound of a steam pot, but Zhang Yuwei knew very well that this had nothing to do with steam, and the reason why there was an "empty" sound was because his Dan energy was constantly compressed in the Dan furnace, so that the internal and external pressure was unbalanced, so there was a "empty" sound, which was a normal performance, but the rest of the people didn't think so, except for Murong Li'er and Qin Xiyan, the rest of the people subconsciously retreated.

"Up!"

Zhang Yuwei's left hand pressed down suddenly, and suddenly, the Dan furnace opened, and a golden and white pill emerged from the Dan furnace, seeing that the pill was white, Zhang Yuwei's face sank slightly, he knew that this was because the quality of the medicinal materials was not high, according to his memory, the semi-finished pills refined at this moment should be pure gold, but the quality of medicinal materials can not be improved by means, so when choosing medicinal materials, you also need enough experience, which is also one of the basics of the alchemist, Zhang Yuwei has tried his best to select high-quality rare medicinal materials, but he is still not satisfied.

It's just that Dan is halfway through practice, there is no reason to give up, Zhang Yuwei clenched his fist tightly with his left hand, and the Dan furnace instantly turned into several golden flames, wrapping the pills in mid-air layer by layer, although the quality of the medicinal materials is not high, but Zhang Yuwei plans to give it a go, and use the unique purification power in his Holy Dao Killing Tianyan to purify the white on Dan's body, under the calcination of the Holy Dao Killing Tianyan, the white on Dan's body gradually becomes smaller, from white stripes to small white dots, and then completely disappears from small white dots, until it becomes a golden pill.

Seeing this, Zhang Yuwei let out a sigh, the Holy Dao Killing Tianyan is an extremely complex flame, the earth's medicinal materials are difficult to withstand the calcination of the Holy Dao Killing Tianyan, the reason why the pill was not burned directly is completely due to Zhang Yuwei's incomparably powerful flame manipulation ability, seeing the golden pill generated, Zhang Yuwei knew that this was the second step completed, he put his right hand on it, and the pill slowly rose into the air, and next, he had to take the last step.

In the sky, it was originally a clear sky, but suddenly it became cloudy, but everyone's eyes were on alchemy, and therefore, until the pill lifted off, everyone found that the sky above their heads was already covered with black clouds, Nanxun Zhenren was a strong person in the Jindan Realm, so she naturally knew this scene, she hurriedly walked out of her room, Murong Li'er looked at Zhang Yuwei with a shocked face, she didn't expect that Zhang Yuwei's alchemy was so strong.

"The vision of heaven and earth, is the thunder coming?"

Nan Xun swallowed her saliva, she followed the crowd and hurried to the main hall of the Zhou family where Zhang Yuwei was, she had seen such a thing before, but she had only seen it once, and there were many more people than now, but the sky of that time was not as dark as it is now, it was just a blue thunderbolt, even then, it caused a sensation, after all, the heavenly thunder is the symbol of the fifth-order pill Cheng Dan.

Of course, Murong Li'er also recognized what was happening, although she had never seen Tianlei, but she had read in the book, the fifth-order elixir, because the condensing pill would be accompanied by a large number of miscellaneous products, so it would attract the heavenly thunder and carry out baptism, only the pill that had been baptized by the heavenly thunder could be regarded as a real Cheng Dan, although she didn't know what kind of pill Zhang Yuwei was refining, but she could confirm that Zhang Yuwei's alchemy was definitely above Murong Wan'er, because Murong Wan'er could not refine the fifth-order pill.

There was a "boom" sound in the sky, a little blue appeared in the dark clouds, this is a sign of the thunder to appear, Zhang Yuwei saw this, his hands were folded, his whole body turned into a thunder body, only to hear the "click" sound, a blue-purple thunder fell from the sky, straight on the pill, Zhang Yuwei hurriedly directed his own thunder and lightning to the pill, because of the circulation of thunder and lightning, the thunder passed to Zhang Yuwei's body along the pill.

"Thunder Emperor Constellation!"

Zhang Yuwei suddenly floated under the terrifying pressure of the thunder, and a phantom of a purple thunder seat appeared on his lower body, on the seat, a man who couldn't see his face clearly, wearing unicorn pattern armor, slowly raised his left hand, only to hear the sound of "boom", the power of the thunder was instantly decomposed into ten parts, after the power of the thunder weakened, the purple seat and the man all disappeared, Zhang Yuwei shook his right hand upward, and at the same time took over the ten heavenly thunders, his right hand violently exerted force, clenched tightly, and put the ten heavenly thunders into the body.

Zhang Yuwei summoned out the phantom of Lei Zu, which is also one of the chapters of the "Thunder Emperor Summoned" exercise "Thunder Emperor Heavenly Seat", although the thunder is terrifying, but under the great shore of the ancestor of ten thousand thunders - Lei Zu, it still seems too small, although Zhang Yuwei can resist this thunder, but he doesn't want to do it, after all, the thunder is quite rare on the earth, if you can receive the system of strengthening yourself in your own body, it would be better, just forcibly suppress the thunder, with Zhang Yu as the current realm is still too low, and therefore, He used the power of the "Thunder Emperor Heavenly Constellation" to decompose the heavenly thunder and collect the heavenly thunder in his body.

After the thunder disappeared, a golden pill slowly fell from the sky, Zhang Yuwei stretched out his right hand, and the pill slowly fell on his right palm.

"It's finally practiced, this Dan meeting is all up to you."
