There were bursts of screams and curses.

Yu Lie turned a blind eye and neatly threw the heads into the alchemy furnace for calcination, waiting for the bone fluid to melt, causing the soul to condense and allow the skull cups and dragon flame crystals in the furnace to grow.

Suddenly, after some calcining, the cups and dragon flame crystals in the alchemy furnace began to buzz and sway.

Yu Lie's calm eyes suddenly became disturbed. He stared at the things in the furnace and thought:

"Is this finally going to change?"

If there are outsiders here, and their sight or consciousness can pass through various barriers, they will find that the cups and dragon flame crystals in the alchemy furnace are already so pure that they can generate light on their own, almost like the world itself.

It's a spiritual thing.

Because for several months, in addition to repeatedly inputting materials to incrementally refine the cups and red pills, Yu Lie also repeatedly used the bronze wine cups to clean out the impurities in them again and again.

What happened in the alchemy furnace at this moment was that the skull cup and the dragon flame crystal were about to completely cross a threshold, and their quality and quantity would be extremely pure!

The purpose of Yu Lie's move was to refine these two things, especially the dragon flame crystal, to a state of perfection that could rival the treasures of heaven and earth, and then use them as the "Fire Piercing Pill" for his breakthrough.

In the dark room, Yu Lie looked at the objects in the alchemy furnace expectantly, feeling slightly nervous.

To be honest, he had already raised the dragon flame crystal to the point where it could be taken as medicine.

It's just that he is currently in another world. Yu Lie has no shortage of materials in his hands, and the turmoil outside is very big. He is not ready to go out, so he simply continues to temper the dragon flame crystal, thinking about excellence.

If this artificially refined object can really reach the level of heavenly materials and earthly treasures, then it will be of great benefit to Yu Lie, and the probability of a successful transformation is extremely high.

But if something bad happens to it after it is refined to the extreme, or it is simply scrapped, then all the rest of the hard work will be in vain.

In nervousness, Yu Lie glanced at the bronze wine cup held in his sleeve and said to himself: "With the wine cup in hand, it can be turned into spiritual energy even if it is used up, so it is not considered completely useless.

Simply give it a try!"

With a thought in his mind, he controlled the alchemy furnace, took out a lot of auxiliary medicines prepared for breakthrough, and placed them in front of him in batches.

Whenever there is a change in the products in the furnace, the remaining columns will add a little bit to guide the effectiveness of the crystallization in the furnace as much as possible and prevent failure.

Buzz!

Suddenly, a dragon flame crystal the size of a pigeon egg turned red and fell into a large amount of bone fluid. It quickly sucked in the souls of other living beings and the dragon flame, and the whole body shrank and contracted, just like breathing.

Under Yu Lie's gaze, a clicking sound was heard, and the dragon flame solidified in the crystal suddenly twisted again, emitting a golden-red light.

This dragon flame actually came out from inside, and in turn enveloped the crystal.

There was a squeaking sound, and under Yu Lie's surprised gaze, this wisp of dragon flames directly burned the crystals formed by the soul, turning them all into a liquid state, lingering in the alchemy furnace, and slowly evaporating.

And it continued to fall into the skull cup made of dozens or hundreds of skulls, twisting and squirming like a wick.

Most of the soul crystals burned into liquid form were also stored in skull cups, becoming like lamp oil.

At the same time, a pure fire energy also escaped uncontrollably from the alchemy furnace, making Yu Lie's spirit suddenly uplifted.

He looked at the alchemy furnace with surprise in his eyes: "What a pure fire energy! Is this the fire-preventing pill made from!?"
