Mortal: I became invincible after becoming sworn brothers with Han Li.

Chapter 179 Five-Year Jade Plaque

Inside the cultivation room, a strange, headless corpse floated in front of Li Yunfan.

The corpse was nearly two zhang tall, covered with black and red demonic patterns, and had a tail covered with scales on its back.

Even though it had been dead for many years, the corpse of this demon still exuded a strong aura of malevolence.

Li Yunfan stared at the corpse of the demon for a long time before waving his hand and placing it aside.

Then he took out dozens of different materials from the storage bag and placed them on the ground one by one.

After taking a deep breath, his expression suddenly turned serious. With a gentle lift of his hand, a shimmering silver material on the ground automatically flew into the air.

Immediately afterward, he opened his mouth, and a ball of purple flame flew out, rushing straight at the shimmering silver material in the air, completely enveloping it and beginning to refine it.

Then, it released the Yellow Spring Poison Fire and the Netherworld Cold Mystic Fire to refine two other materials next to the Purple Nether Heart Fire.

After doing all this, Li Yunfan closed his eyes and circulated his cultivation technique to recover his depleted spiritual power. At the same time, he released his divine sense to observe the degree of refinement of the three flames.

With the aid of the three types of flames, he completed the refining of all the materials in just a few months.

However, this is only the simplest step. Next, he will also refine the corpse of the evil demon so that it can be fused with various materials.

With a thought, Li Yunfan unleashed the Purple Nether Heart Flame upon the demon's corpse, which then rapidly spread throughout his body.

Knowing that this refining process would only take longer, he closed his eyes again.

When he opened his eyes again, three months had passed.

Looking closely at the corpse of the demon before him, its appearance had already undergone tremendous changes.

First of all, the body size has been shrunk to the height of a normal person. Apart from the lack of a head, the whole body looks very symmetrical and coordinated.

Secondly, the black and red demonic patterns on the surface of the corpse turned purplish-red after being refined by the Purple Nether Heart Fire.

Finally, the dense malevolent aura emanating from the corpse is no longer perceptible; it has all been absorbed into the corpse.

Li Yunfan revealed a satisfied smile and opened his mouth to retract the Purple Nether Heart Flame into his body.

After such a long period of refining, the fire has weakened somewhat and needs to rest and recuperate within the body for a while before it can recover.

In the blink of an eye, five years have quietly passed.

At this moment, the cultivation room in Li Yunfan's cave was already filled with all sorts of things.

-

In the corner, dozens of puppets stood haphazardly together, most of them beast-like puppets, with only ten humanoid puppets holding bows and arrows.

In another corner, two burly men with different appearances stood quietly side by side, looking almost identical to real people.

His expression was blank, and his eyes were devoid of any spirit, like a wooden figure, devoid of any soul.

On the floor of the cultivation room, various jade bottles and wooden boxes were scattered haphazardly, almost covering the entire floor.

However, among these jade bottles and wooden boxes, there were also some things that shimmered with spiritual light.

Upon closer inspection, they turned out to be all sorts of magical artifacts!

The most common items were low-tier and mid-tier magic artifacts, followed by high-tier magic artifacts, and finally two ordinary top-tier magic artifacts!

All of these were created by Li Yunfan on his own over the years.

The initial corpse of the demon was not very well made because it was the first time it had been crafted.

It is estimated that it can only exert the strength of the early stage of Foundation Establishment.

After summarizing the shortcomings in the refining process, they began to refine Yue Tian's corpse.

This time, having learned from past mistakes, the refining was quite successful.

It can enable it to unleash the strength of the mid-Foundation Establishment stage!

After completing the refining of both corpses, he only recuperated for a few months before throwing himself into the refining of puppets.

The few puppets he had back then had been almost used up when he was in the abandoned cave, so naturally he needed to refine some more.

He had thought of this when he went to the market with his sister, so he bought some materials for making puppets.

After squandering all the materials, he spent several months recuperating before beginning to hone his craft.

From the initial scraps he forged to his first low-grade magic weapon, his proficiency increased day by day.

Once he felt he had a good grasp of the craft, he immediately began to try refining mid-level magic artifacts, and then high-level ones.

Finally, using iron essence, copper essence, and other materials purchased from the Treasure Pavilion, and after several failures, he finally managed to forge two of the most ordinary top-tier magical artifacts.

— He opened his eyes, a glint of light flashing in his eyes. His cultivation had also improved considerably in the past five years.

With a wave of his hand, a red spiritual energy swept across, collecting the wooden box, jade bottle, and magical artifacts on the ground, as well as the puppet and two refined corpses in the corner, into his storage bag. Then, with a flash of spiritual light, a square jade box with a sealing talisman appeared in his hand.

Stroking the jade box, Li Yunfan pondered for a long time before finally putting it away.

He then took out a jade slip, immersed his divine sense into it, examined it for a while, and then put it back into his storage bag.

Immediately afterwards, he got up and walked to the stone wall of the cultivation room. He waved his hand and released a magic weapon longsword, using his divine sense to control it to carve complex spiritual runes on the stone wall.

An hour later, the stone walls of the entire cultivation room were covered with dense spiritual patterns.

Then he released four white array flags and planted them in the four corners of the training room.

After doing all this, Li Yunfan took out a palm-sized array plate, made a hand seal with his right hand, chanted an incantation, and then pointed a finger at the array plate.

The four array flags suddenly emitted a bright white light, and the spiritual patterns on the four stone walls also gradually lit up with white spiritual light!

With a muffled "hum", a transparent light curtain gradually emerged from the stone wall, eventually forming a whole that enveloped the training room.

The formation that Li Yunfan set up was the same formation that isolated spiritual energy and consciousness on the altar.

With his current cultivation level and expertise in formations, he gained new insights when looking at this formation again.

"Even with my current level of spiritual power, I can't detect the existence of this formation. It truly lives up to its reputation as an ancient formation. It seems I'll have to study it more thoroughly in the future!" Li Yunfan thought to himself.

Although he had already set up this array to isolate spiritual power and divine sense, he was still somewhat uneasy when he thought of the sealing talisman on the jade box.

So he took out another set of defensive formations and set them up in the training room.

With this double protection, Li Yunfan finally felt a little relieved.

After sitting cross-legged on the futon again, he took out the jade box once more.

With a solemn expression, he tore off the sealing talisman and then slowly opened the jade box.

Inside was a fist-sized, half-section milky-white jade tablet, covered with tiny silver runes that appeared and disappeared, making it quite mysterious.

"What is this?" Li Yunfan stared in astonishment at the broken jade tablet, his mind filled with doubt.

Just as he was about to examine it closely, the silver runes on the jade tablet suddenly flashed wildly, then transformed into a beam of silver light that shot out and crashed directly into the inner defensive formation!

It was unclear what this jade tablet was, but the defensive formation only managed to block it for a moment before being struck by the jade tablet and developing cracks.

There were clear signs that they would break through the formation at any moment!
