Chi Shuyan first took out a bottle of Spirit Gathering Pills which she had refined before. After swallowing one pill, she immediately chanted the fourth level of the Mystic Yin Arts and tried to raise her circulating spiritual energy to the consummate level. Unfortunately, the further she went, the more spiritual energy she needed, so Chi Shuyan could only keep taking Spirit Gathering Pills.

Although the Spirit Gathering Pill was a low-grade version, it was much more effective than the Energy Recovery Pill. In order to advance this time, Chi Shuyan swallowed all the Spirit Gathering Pills she had refined before. Only then was she just barely able to circulate her spiritual energy to the consummate level before she could advance.

Spiritual light spilled out of Chi Shuyan’s body, which overflowed with dense spiritual energy.

The spiritual energy fluctuations wreaked havoc in the room, which looked like it had been hit with a hurricane.

Advancing at lower levels wasn’t dangerous. Furthermore, when she fought the evil cultivator previously, she had faintly sensed her body overflowing with spiritual energy. She had already consumed a lot of Spirit Gathering Pills to enhance her cultivation, so her advancement was smooth sailing. After a while, with a bang, Chi Shuyan broke through the barrier without much effort and finally advanced to the fourth level of the Mystic Yin Arts.

She vaguely felt that the fifth level of the Mystic Yin Arts was a turning point, and successfully entering the sixth level would definitely be a different type of delight.

It was a pity that the first to fifth levels of the Mystic Yin Arts were still considered low levels. The further one went, the harder it became, and the more spiritual energy was needed.

What Earth lacked the most was spiritual energy. She had the vague feeling that the sixth level would be the highest she could cultivate, unless she had some fortuitous encounter.

But she didn’t dwell on advancing, and would let nature take its course.

Besides, although she had already entered the fourth level of the Mystic Yin Arts, she was still far from the sixth level.

After advancing, Chi Shuyan withdrew her spiritual energy. She gazed at the messy bedroom, which looked like the scene of a robbery. Chi Shuyan immediately threw out a Cleaning Talisman, and everything in the bedroom returned to its original state.

Chi Shuyan heaved a sigh of relief when she saw the tidy bedroom.

After her advancement, she vaguely felt that the spiritual energy around her had become more abundant and increasingly dense.

She casually took out the ring which she had wanted to give to Qi Zhenbai before. She poured spiritual energy into it, and in just ten minutes, the ring was actually directly upgraded to an elementary level 3 magic weapon.

For some reason, Chi Shuyan suddenly thought of the storage ring forging method mentioned in the Mystic Yin Arts. She was immediately interested and withdrew her spiritual energy.

When she found the Iron Essence which Fu Shiyin had given her, Chi Shuyan once again circulated her spiritual energy and lit a fire. She added some of the Iron Essence to the jade ring and controlled the intensity of the flame as she washed the ring with her spiritual energy.

Chi Shuyan persisted for more than a few hours. It was her first time trying to refine a storage ring, so her movements were very clumsy. In addition, the steps to refining a storage ring were complicated and required a lot of spiritual energy.

After a while, cold sweat broke out on her forehead.

Chi Shuyan continued to send in more spiritual energy. At that moment, the jade ring let out a cry as if it had a mind of its own and wanted to escape. Chi Shuyan narrowed her eyes and had her spiritual energy pull back the jade ring before it could escape.

After she withdrew her spiritual energy, Chi Shuyan took a few Energy Recovery Pills. Once her spiritual energy recovered, she began to observe the storage ring she had refined. Because it was her first time refining this thing, she didn’t know if she had succeeded or not, so she was quite nervous.

Whether she succeeded or not, Chi Shuyan found that she had directly upgraded the jade ring to a mid-grade level 4 magic weapon. She restrained her thoughts and probed the space inside, and found that it was about dozens of square meters in size.

She had a vague feeling that the reason why the jade ring’s level was so high as soon as it was forged into a storage ring was probably because of the Iron Essence.

For a moment, Chi Shuyan didn’t know whether to be disappointed or happy.

She didn’t forget that the Mystic Yin Arts mentioned that the supreme gods refined Sumeru Rings, which were commonly known as spatial rings. All sorts of flowers, plants and trees could grow inside, and they were called small worlds.

Fine, it was better not to compare herself with those bigshots. She was quite satisfied with these dozens of square meters. Although the space was bare and had no plants, it was still quite convenient for storing things.
