Gu Yan placed her in Hua Qingyue's arms, ignoring her angry expression, and walked in laughing.

Gu Yan found a room and went to cultivate. He wondered if he could absorb spiritual energy to improve his cultivation after his wings grew.

After closing his eyes for a few minutes, he took out the blue spirit stone and began to absorb it.

The speed was noticeably faster, and in no time, Gu Yan was enveloped by the faint blue mist.

At the same time, his aura was gradually rising, showing a faint trend of breaking through the bottleneck.

It wasn't until 5 a.m. the next day.

A loud bang was heard.

Gu Yanshen's aura surged directly into the seventh level of the Spirit Opening Realm. He did not stop cultivating, but continued to absorb spiritual energy to stabilize his cultivation.

Half an hour later, Gu Yan opened his eyes. With a thought, his divine sense expanded to twice its original size, covering a radius of a hundred meters as if it were right before his eyes, and the figures of the women were as if they were right in front of him.

Gu Yan summoned real fire, which doubled in size, and the temperature seemed to rise considerably.

Suddenly, Gu Yan summoned the furnace, which crashed to the ground with a thud.

This size is big enough to fit two or three people inside without any problem.

He then stuffed in over a hundred old ginseng roots and began to temper them with real fire.

After more than ten minutes, Gu Yan's face lit up with joy. It really worked! So he focused all his attention on refining it.

It seems the alchemy furnace is the reason. He felt that not a trace of medicinal power was leaking out. No wonder everyone says that an alchemy furnace is necessary. So that's the reason. Gu Yan thought to himself.

After more than half an hour, under Gu Yan's increasingly skilled control, sixty pills were directly condensed, and their quality was excellent, feeling like they were a level higher than the previous Body Tempering Pills.

"Let's call it the Supreme Pill," Gu Yan thought to himself.

Then he put the residue into his storage ring and added thousands of herbs, all of which were unsuitable for making pills and could only be used to refine medicinal liquid.

Gu Yan urged his hands to channel spiritual energy, just like constantly supplying gasoline to an engine to ensure its vigorous operation.

After a while, a small stream was drawn up by Gu Yan, and a refreshing fragrance immediately wafted out.

While manipulating the medicinal liquid, Gu Yan took out five pieces of jade, polished them, and finally melted the powder into the shape of a large bucket before putting the medicinal liquid in.

Gu Yan was very satisfied this time; efficiency and quality had improved several times over, and most importantly, the alchemy furnace could finally be turned on.
