Seeing that Shizun and his senior brothers and sisters had left, Lu Yu couldn't wait to run to the desk and sit down, and began to try to collect refining aura.

He flipped to the corresponding page and read it word by word.

"Speaking of this, the collection of aura mainly relies on the Zhihai and Dantian to operate the aura to capture the aura of similar texture."

"It's no wonder that when Master Venerable was guiding me to achieve the body of a primordial immortal, he had to specially input some pure aura into my dantian. I see, it's useful. Lu Yu sighed.

"Okay, here we go!" Lu Yu walked to the light blue Thousand Machine Silk Practice Mat and sat down.

"Reiki, receive." Lu Mian recited the mantra, closed his eyes and quietly felt the spectacle of aura attracting homogeneity.

Sure enough, the pure aura that remained in the dantian in Lu Xi's body began to spread out of his body into the air. And the heaven and earth suddenly quieted down, and the aura that was so quiet that it could not tolerate the slightest sound made Lu Yu shudder.

"How do you suddenly feel like you're in space? I'm still sitting on the practice mat. ”

Lu Yu didn't dare to open his eyes, he only felt a trace of more and more majestic pure aura approaching his dantian, those pure aura seemed to float from the extremely cold place between heaven and earth, and when it flowed into Lu Xian's dantian, he felt cold and unbearable. After a while, his dantian was as cold as an ice cellar. However, Lu Yu did not get a cold or typhoid fever, but felt cold and refreshing.

This kind of refreshing feeling is incomparable to drinking ice drinks.

Lu Yu liked this feeling very much, not only the dantian, but even the whole body cooled down, but there was no discomfort at all.

Gradually, those spiritual qi that drifted into Lu Xi's dantian from the extremely cold land seemed to be aware of Lu Xi's greedy collection, and gradually slowed down the speed of floating over, and finally stopped abruptly in an instant.

Lu Yu stretched out contentedly. He looked down at his dantian, which had now been infused with a large amount of cold essence pure aura.

Lu Yu even felt like a blooming iceberg snow lotus, blooming proudly and freely between heaven and earth.

"Haha, that's cool! The first time I tried to collect Reiki, I got so much pure cold Aura. Lu Yu encouraged himself and said, "Next, I will try to preserve all these spiritual qi permanently, refine all of them into spiritual energy solid yuan pills, and let the master take a good look!" ”

Lu Yu did what he said and closed his eyes again. He silently recited the mantra: "Spiritual Qi solidifies the Yuan Dan, refine." ”

The gas-like aura in the dantian obediently gathered, crowded with each other, collided, contracted, and gathered, constantly compressed and condensed, and the density became larger and heavier.

Lu Yu clearly felt that the dantian had become very empty, and the originally crowded gas-like aura was compressed by him into thumb-sized aura solid yuan pills. The Spiritual Qi Guyuan Dan floated in the infinite space in the dantian, glowing with a pale yellow glow, and looked like a group of fluorescent fireflies from a distance.

Lu Yu didn't know how to absorb or use these Spiritual Qi Solid Yuan Pills, so he transported them out of the dantian and placed them in the palm of his hand.

"Listening to the master, this aura solid yuan pill is extremely volatile. I had to find a container that was very well sealed and put them in place. Lu Yu thought of his rectangular iron piggy bank, which still had a few coins and a few pieces of paper money in it, forget it, let's borrow it first.

Lu Yu ran to the bedside table, opened the drawer and took out the piggy bank, took out the money inside and put it in the mezzanine of the schoolbag, and then carefully put all eight Spiritual Qi Guyuan Pills that were cold to the touch into the piggy bank.
