"Just let Senior Brother Qiu Lin and Senior Sister Tianlian'er be alone for a while longer. They have all been wronged by each other all these years, and they should have a lot to say to each other at this time. I'm not going to bother them, just go back to the dorm. Lu Yu thought and quickened his pace.

Back in the courtyard of his dormitory, Lu Yu simply changed into casual clothes and began to practice before going to bed, practicing the operation of Spiritual Qi and refining the Spiritual Qi Solid Yuan Pill.

Lu Yu walked to his desk and flipped through the introductory chapter of the aura cultivation law.

After reviewing it, Lu Yu found his thousand-machine silk practice mat and spread it on the open space in front of the desk.

Lu Yu sat down on the practice mat and began to concentrate on pranayama.

Lu Yu silently recited the mantra. The aura in the dantian began to float obediently. Lu Yu continued to recite the mental mantra silently, and the spiritual energy in his dantian began to condense together continuously, compressing and refining into the spiritual qi solid yuan pill.

The smooth and round Spiritual Qi Gu Yuan Dan gradually solidified and formed, and then entered Lu Xi's dantian to remain.

Lu Yu hurried his luck and sent out those Spiritual Qi Guyuan Dantong Universal Spiritual Qi Supports, and transported them directly from his dantian to the bamboo mat in front of the practice mat.

Refining the Spiritual Qi Solid Yuan Pill was a long process, and Lu Yu wanted to refine all the stored Spiritual Qi in the dantian into the Spiritual Qi Solid Yuan Pill, and then store it in the Tianzhi box.

In this way, he can collect new spiritual energy from the outside world and put it into his dantian.

After a long time, Lu Yu finally refined all the spiritual energy in the dantian into the spiritual energy solid yuan pill. He opened his eyes, looked at the bamboo mat in front of him, and counted carefully.

There are a total of sixteen Spiritual Qi Solid Yuan Pills. These Spiritual Qi Guyuan Pills are uniform in size, but their purity is not high, and they look white and glutinous, with some turbidity.

Lu Yu immediately thought of the alchemy furnace given to him by Qiu Lin, which could be used to purify the Spiritual Qi Gu Yuan Pill and refine these Dan bodies to purity.

"This alchemy furnace is small and round, the inner tank inside is gold, and the outside of the belly is made of volcanic essence crystalline rock. I'll give it a name, let's call it the Golden Crystal Furnace. Lu Mian muttered to himself.

Before Lu Yu collected these sixteen Spiritual Qi Guyuan Pills and put them into the Tianzhi Box, he also wanted to refine them to be more refined. So he opened the lid of the golden crystal furnace and put all sixteen of them inside.

The Golden Crystal Furnace was like a living furnace, and it sensed that the sixteen Spiritual Qi Solid Yuan Pills in the inner tank were still very turbid, and immediately began to condense and purify these Spiritual Qi Solid Yuan Pills.

The Aura Gu Yuan Dan made a crisp sound of collision in the inner tank of the furnace.

"Ding Ding Dong Dong."

After a short period of time, the aura Gu Yuan Dan in the inner tank suddenly stopped colliding with the inner wall of the inner tank, and all of them stopped.

Lu Yu exclaimed: "Wow, the efficiency of this furnace is really high, has it only taken such a short time to purify all these turbid spiritual qi solid yuan pills?" I'll take a look. ”

Lu Yu immediately opened the lid of the golden crystal furnace and looked inside.

Really, those Spiritual Qi Solid Yuan Pills were all purified and refined into smaller granules, and they were all very pure and transparent, almost transparent, and their surfaces exuded a milky white light.

Lu Yu remembered that Senior Sister Tianlian'er had told him before that the Spiritual Qi Gu Yuan Dan was easy to vaporize. So he took out the sixteen pure Spiritual Qi Gu Yuan Pills and quickly put them into his storage artifact Tianzhi box.

He also put the practice mat and the golden crystal furnace into the closet, and then walked to the couch, lay down on the couch, and prepared to fall asleep.
