After gathering her mood, Liu Yu closed her eyes and sat cross-legged for a while, getting familiar with her consciousness after the surge.

Then he turned his eyes and looked at the jade box beside him, and opened it with a burst of magic power.

"Click"

The next moment, the jade box opened gently, revealing a green spiritual grass that resembled a real dragon.

It’s the Dragon Grass!

This Hualong Grass obtained from Yishan Yifu is only a little more than five thousand years old, and its improvement to the physical body is extremely impressive.

"Hualong grass can not only increase the strength of the physical body, but also cleanse the hair and cut the marrow to improve the qualifications of the physical body, causing the mortal body to gradually transform into the spiritual body and the Taoist body."

"Although Tiannan's body-refining resources are extremely scarce, that is only in relative terms. Compared with ordinary True Lords, their own resources are not many, and their progress in body-refining is not slow."

"After so many years, I am gradually approaching the peak of the early stage of the fourth level."

"Of course, this kind of speed is completely inadequate compared to the speed of improvement in Qi refining cultivation."

"But now that we have Dragon Transformation Grass, the time it takes to break through to the middle stage of the fourth level should be greatly shortened."

Looking at the spiritual grass that looked like a real dragon, various thoughts flashed through Liu Yu's mind.

With the Immortal Mansion as a support, and being a master of alchemy himself, he can refine the spiritual herbs into spiritual elixirs.

By exchanging the fourth-level elixir for the required resources and frequently participating in various exchange meetings, he could still use a body-refining resource every once in a while.

Although resources are relatively scarce, high-level resources are in the hands of Nascent Soul monks, and most of the monks in the world of immortal cultivation are legal cultivators.

Liu Yu possesses the fourth-level elixir, which means he has core competitiveness. He does not need to go out frequently to take risks, and can obtain the required body refining resources through transactions.

After all, for Dharma practitioners, spiritual objects for body refining are of limited use and are far less effective than spiritual elixirs for improving cultivation.

Some people are willing to exchange elixirs, and of course they are willing to do such a thing that benefits both parties.

All kinds of thoughts flashed through his mind, and Liu Yu immediately took out a jade bowl and a medicine pestle.

Immediately, he placed the jade bowl on the ground, carefully picked up the spiritual grass that looked like a real dragon, and used his right hand to move it like a knife.

"Shua~"

The next moment, the Dragon Transformation Grass split into two.

About a third of the way, a long dragon tail fell into the jade bowl below.

Although this spiritual herb is powerful, it is extremely simple to take, and there is no need to refine it into a pill or prepare it into a potion.

When using, grind it directly into liquid, and then apply it evenly on the body surface to achieve maximum effect.

"Click"

Then, Liu Yu quickly put most of the remaining Dragon Transformation Grass into the original jade box and sealed it to prevent the medicinal power from being lost in vain.

Looking at a small piece of spiritual grass in the jade bowl, he picked up the medicine pestle and began to grind it.

"Bangbangbang~"

Soon, the rhythmic grinding sound could be heard in the practice room.

Under Liu Yu's tinkering, the jade bowl overflowed with juice, and the lavender liquid containing abundant spiritual power continued to overflow from the pale green spiritual grass.

As time passed, about half a quarter of an hour later, the original small half of the "dragon tail" in the bowl disappeared, turning into a small bowl of lavender spiritual liquid.

"Puff~"

In the lavender liquid, tiny bubbles kept popping up, exuding steam.

Every ray of hot air contains amazing spiritual power and is of extremely high quality.

With almost a wisp of air, the total amount of spiritual power exceeds that of a high-grade spiritual stone!

As time went by, after only a few breaths passed, the temperature of the lavender liquid became comparable to that of magma, and the trend of continuing to rise was very obvious.

If this continues, the bowl made of spiritual jade will not last long.

"Snapped"

In order not to waste the power of the medicine, Liu Yu gently placed the jade bowl on the ground, and then quickly took off his shirt.

Those muscles like cast iron and a figure with golden proportions were exposed to the air again!

The next moment, he stretched out his hand.

In the jade bowl, the lavender liquid that was gradually boiling suddenly made waves on the water surface.

Then, a thin stream of water rose into the sky, slowly flew towards Liu Yu, and landed on the burly bronze body.

"Wow!"

Under the precise control of his spiritual consciousness, the purple liquid ground into dragon grass was evenly distributed on every inch of his skin.

Of course, the thick and powerful legs below and the energetic "dragon" are no exception, leaving no blind spots.

After contacting the skin, the purple liquid instantly became viscous and did not slide down like water.

Cool and warm.

The temperature is just right and I don't feel anything.

Liquid hotter than magma was spread evenly on the surface of the body. This was Liu Yu's first feeling.

After all, he is at the fourth level of body refining. Both his physical strength and spell resistance are already very high, and his vitality is also very tenacious.

Under normal circumstances, if you can resist a few real treasure bombardments with your physical body, there won't be any big problems.

"Zizi~"

However, after becoming viscous, the temperature of the purple liquid continued to increase rapidly, and the temperature of the entire practice room also increased rapidly.

After a few breaths, even Liu Yu now felt a little "hot".

"Don't waste the power of medicine."

With this thought in mind, he sat cross-legged and activated the fourth level of the "Star True Body" technique.

"Boom!!!"

The next moment, the powerful spiritual pressure formed a storm and swept through the entire training room.

On Liu Yu's chest, the arc-shaped pattern formed by nine large acupoints lit up, and three-color auras of red, bright silver, and blue appeared, representing the sun, moon, and stars respectively.

The three-color auras complement each other, and what appears within them seems to contain the mysteries of the birth and destruction of stars.

As the technique was running, the temperature of the purple liquid on the surface of his body increased rapidly, gradually turning from lavender to purple-red.

In a short period of time, Liu Yu actually felt a "burning" feeling.

But he still restrained his mind, suppressed his body's instinctive reaction, and devoted himself to operating the "Star True Body".

Under the observation of his spiritual consciousness, wisps of extremely high-quality lavender spiritual power were continuously absorbed by the physical body as the technique moved, and converged towards the circular pattern on the chest, just like a river flowing into the sea.

During this process, the bones, flesh, and meridians are tempered by the power of the dragon-changing herb, becoming tougher and harder, and the vitality is further improved.

"Huh~"

After more than ten breaths, Liu Yu exhaled a breath of hot air.

At this time, his entire body turned red, like a red-hot iron.

Every inch of flesh and blood seems to be calcined by hot flames, and the essence of life is improved bit by bit in the process.

Become an immortal through a hundred refinements!

The purple-red liquid turned into a hard shell, enveloping Liu Yu's entire body, which looked a bit weird and terrifying.

During the intense calcination, sweat kept appearing on his forehead and temples, but it often evaporated out of thin air before it had time to flow down.

The originally bronze skin now turned red, with grayish white or black impurities constantly being discharged.

At this moment, Liu Yu felt like she was in a melting pot!

…

Time passed slowly, I don’t know how long it has passed.

But at this time, the temperature inside the training room had reached an alarming level.

Even the hard sunstone turned into a liquid state and dripped on the ground, plunging the entire room into darkness.

If it weren't for the fact that the walls and floors were all made of spiritual materials of level three or above, they would have been riddled with holes.

"Dong dong dong~~"

There was no light in the darkness, but there was a steady heartbeat, sounding rhythmically like a war drum.

Listening to the sound and following the light source, I saw that the heartbeat sounding like a war drum was a "big cocoon".

A faint spiritual light circulates in the large cocoon, and the entire body has turned gray-white, with the purple aura becoming dimmer as time goes by.

As the purple aura dimmed, a strange power became stronger and stronger, as if a great beast was about to awaken.

"Click~~"

Half a quarter of an hour later, the last trace of aura of the cocoon disappeared, and cracks appeared on the surface, spreading rapidly like a spider web.
