Chu Wei's body was surrounded by a stream of warm medicinal liquid, enveloping him.

The inside of the Dan furnace was not pitch black, but there was a colorful light, which came from the heavenly treasures in the medicinal liquid.

Chu Wei was not soaked in the medicinal liquid, his whole body was floating in the air, surrounded by the medicinal liquid, as if he was in a bubble.

He spread out his spiritual consciousness and shrouded the surrounding medicinal materials, he wanted to see what kind of structure these medicinal materials were, and to understand them, maybe it would be useful for him to practice alchemy in the future.

Besides, if you want to understand the process of alchemy, is there a more intuitive way than to let yourself and the medicinal materials be refined together?

This method of observing alchemy, it is estimated that no one has thought of it, and few people will try it.

The more Chu Wei thought about it, the more he felt that this was an unavoidable opportunity, and he immediately watched it intently.

He locked his spiritual sense on one of the small blue grasses, this grass had seven leaves, emitting blue fluorescence, very beautiful, Chu Wei didn't know what kind of grass it was, but he remembered the characteristics of the small grass in his heart.

Slowly, his spiritual sense seeped into the small grass leaves, and he saw small blue liquid bubbles, and he also saw pipes transporting blue liquid.

When his spiritual sense seeped into the grass's torso, he saw a membrane-like barrier within, and a blue liquid was also present.

At this moment, the liquid is being squeezed, seeping out of the grass and immersed in the solution in the Dan furnace.

Chu Wei's eyes showed enlightenment, but he was also puzzled, and then he extended his spiritual sense to another medicinal herb, which was a silver bone, which looked a little like a collarbone, and there were countless small holes in the collarbone, some places were dense, and some places were loose.

What made Chu Wei's expression move was that there was black powder mixed in this bone, and it was also being sucked out by a force at this moment, making Chu Wei think about it while extending his spiritual sense to other medicinal materials......

Time passed breath by breath, Chu Wei didn't know how many medicinal materials he had observed, and at this time, the medicinal liquid around him was even brighter, and the temperature in the Dan furnace was also rising continuously, even if Chu Wei was casting a spirit ten times, it was a little unbearable.

Chu Wei had to give up studying the structure and decomposition process of the medicinal herbs, and sat cross-legged in the bubbles to resist the high temperature in the Dan furnace.

Two days later, Chu Wei was already sweating, his body was trembling, his teeth were clenched, and the pores of his whole body were basically completely stretched, and at this moment, outside the Dan furnace, Wu Qing slapped at the Dan furnace.

Airplanes~

Under a slap, the Dan furnace vibrate, and the liquid medicine that had turned into a colorful pill in the Dan furnace turned into silk threads, brushing together, going straight to the pores of Chu Wei's body, connecting with his pores, and constantly transporting the liquid medicine into his body.

When the silk thread of the liquid medicine drilled into Chu Wei's body, Chu Wei's body returned to quiet, relaxed, and seemed to be no longer so hot, but felt very comfortable.

However, this state had not lasted until ten breaths, Chu Wei's body shook suddenly, his mouth opened wide, and his face twisted, and he let out a terrifying howl, as if he was in great pain.

"Ah......h

His miserable screams came out through the Dan furnace, and Mo Qingfan and Wu Qing sighed when they heard it, and they could only hope that Chu Xiao could persevere.

"Replenishing the innate qi and blood, such as cutting bones and extracting marrow, the pain endured by ordinary people cannot imagine, but this is not tempering your will, I believe in you, you will definitely be able to do it."

Mo Qingfan's voice reached Chu Xiao's ears through the Dan Furnace, making him quiet, but then there was an even more terrible scream in the Dan Furnace.

"Ahhh......h

Ten days later.

Wu Qing slowly withdrew the Danhuo, slapped the lid of the furnace with his palm, and a thick mist rose, and then he counted the points on the Dan furnace, and a large amount of filthy and discarded things flew out of the Dan furnace with the white mist.

When all the medicinal residues in the Dan furnace were discharged, the lid of the furnace fell, sealing the Dan furnace again, Wu Qing sat back in the void, spit out the purple Dan fire, and then refined Chu Xiao.

At this moment, Chu Wei was no longer sitting in the Dan furnace, but floating in the Dan furnace, the clothes on his body seemed to be corroded and tattered, and the exposed skin was bright red.

The pores around his body are still connected by dense colorful light filaments, which makes his body bruise, his masseter muscles bulge, and his mouth keeps roaring, trembling all the time.

The pain in his body was like thousands of needles piercing all over his body, and it was twitching all the time, but such a sharp pain, Chu Wei had endured it for ten days.

This kind of pain made his will blurred, if there is anything else that supports him and makes him persist until now, it is only the concern for his father in his heart!

Filial piety comes first.

Chu Wei has been dependent on his father since he was a child, and everything he does now is so that his father can live a good life.

"No, I can't die, otherwise, what will my father do?"

Originally, Chu Wei didn't want to think about it, but at this moment, he had to think about it, only by letting himself be afraid, he could persevere and survive the tempering of the Dan Furnace.

......

When Chu Zhengnan's short sword for Chu Wei changed, there was always a thought lingering in Chu Wei's mind.

"Dad is not an ordinary person!"

The power of the silver light sword, the moment Fan Gui was instantly killed by the silver light sword, it was deeply engraved in Chu Xiao's heart, he did not let go of this matter, but after returning to the sect, he began to consult the introduction information about the magic weapon.

Let Chu Wei also have a certain understanding of the magic weapon, which is divided into three types, magic weapon, spirit weapon and spirit treasure.

And the four words that Fan Gui said before he died were clearly heard by Chu Wei, and after Chu Wei understood the magic weapon, his heart set off a monstrous wave, and his heart shook violently.

He didn't dare to continue thinking about his father.

Fan Gui said that the silver light sword was a spiritual treasure that protected the path, which means that the silver light sword given to him by Chu Zhengnan belonged to the spirit treasure.

The spiritual treasure is something that even the Infant Realm monks dream of, but his father has one, and he gave it to himself.

In Chu Wei's mind, his father would give him the spirit treasure and become his guardian spirit treasure, one is to protect Chu Wei, and the second point should be that this spirit treasure is no longer useful to his father, or Chu Zhengnan can no longer use the silver light sword.

Thinking of the conversation he once had with Cheng Yuanxiong, Cheng Yuanxiong must have known that his father was a monk, and the one who could use the spirit treasure was probably an infant realm monk.

But how could such a monk feel at ease in a remote mountain village to work and teach his children?

And let Chu Wei go to Beijing to take the test to gain fame, instead of teaching Chu Wei to practice and become a monk?

And most importantly, he began to suspect his father's statement that his mother died in childbirth.

All kinds of questions surfaced in Chu Wei's mind, and finally Chu Wei came to a conclusion.

"Dad must have encountered a huge change before, and it is very likely that this change will continue......"
