Chapter 589

"Rat Immortal … No wonder I felt a familiar aura just now …" Han Li's eyes flashed as he muttered to himself.

The purple-robed male corpse in front of him was actually a Rat Immortal, just like Mo Yu whom he met in the Netherfrost Celestial Abode.

His gaze moved back and forth between the male corpse and the giant rat's corpse, then he looked at the condensed evil spirit around him. He immediately understood that the reason why the evil spirit in this abyss was so dense and terrifying was because of the two of them.

Han Li did not get too close. He only walked around the Rat Immortal's corpse, but he did not see too many wounds on its body. He only saw a jagged wound on the right temple of its head. It seemed to have decayed as there was a layer of dark green rust on it.

Judging from the situation at the scene, the giant rat and the Rat Immortal must have had a great battle here, and they perished together in the end.

This huge abyss that was two thousand miles deep might have been left behind after their great battle.

Han Li withdrew his gaze from the Rat Immortal's body and looked at the giant rat's corpse again. A hint of contemplation flashed through his eyes.

"It's been dead for god knows how many tens of thousands of years, but there's still such a strong spiritual fluctuation in its corpse. If Jin Tong devoured it, it might be able to help him improve his cultivation realm …"

As soon as he thought of this, Han Li's gaze fell on the giant rat's two dark green teeth that were as big as doors. He raised one of his hands, and a Green Bamboo Cloudswarm Sword appeared in his palm with a flash of light.

The Celestial Spiritual Power in his body was activated, and the long sword in his hand slashed at the root of the giant rat's teeth.

"Clang!" A sharp sound was heard.

A strong sword light fell on the root of the giant tooth, and a dark green light suddenly lit up.

A circle of strong sword Qi wrapped in dark green light rippled out, and a wave of strong corrosive aura came from it.

Han Li's body shone with a green light, and he waved his sleeve to isolate the aura.

After a dozen breaths, the aura wave gradually dissipated.

Han Li raised his eyebrows. He was not surprised, but happy.

Although he did not use all of his strength in that attack, it was still not something that could be easily blocked. It seemed that he had really picked up a treasure.

With that thought in mind, his hand lit up again as he summoned three Bamboo Cloudswarm Swords. The three swords combined into one, and golden lightning coiled around the swords. Ancient Sword Qi shot out at the same time, slashing toward the root of the giant tooth.

There was a cracking sound.

Only then did the two door-sized dark green teeth break and fall from the giant rat's mouth.

Han Li exhaled softly and put away the longsword. With a flick of his sleeve, he put it away into his storage bracelet.

Then, he turned around and walked to the Rat Immortal's corpse. He sized it up.

The Rat Immortal's purple robe should be a pretty good magic robe, but it was a pity that it was already damaged.

Han Li waved his hand and a green light shot out, flipping the corpse over.

Patter!

A grey sack fell from the corpse.

His eyes lit up with joy, and he quickly picked up the bag. After he sent his divine sense into it, his eyes lit up with joy.

This cloth bag was indeed a storage artifact.

He waved his hand, and a small pile of things appeared on the ground.

Han Li frowned slightly. He did not expect there to be so few things, but it was still better than the giant rat.

Moreover, most of the things were made of various materials, and most of them were gray, black, and other monotonous colors.

"Eh!"

Han Li's eyes swept across and he could not help but let out a soft cry of surprise. His eyes fell on a few fist-sized black crystals.

These objects were black and shiny, and their surface was covered with a layer of black light. It seemed as if they could swallow all the surrounding light. At the same time, they emitted a strong fluctuation of the power of the law. They were the Black Marrow Crystals, the main material used to refine the Void Essence Pill.

Moreover, these Black Marrow Crystals were far superior to the Black Marrow Crystals that Jiao San gave him in the past, be it in color or the fluctuation of the law.

Han Li waved his hand and a green light shot out. He held up a Black Marrow Crystal and looked at it carefully. Then, he waved his hand and kept the Black Marrow Crystals.

Other than the Black Marrow Crystals, Han Li did not recognize most of the materials on the ground. However, many of them emitted a strong fluctuation of aura that was not weaker than the Black Marrow Crystals.

In particular, three of the items emitted an especially strong fluctuation of aura that was even stronger than the Black Marrow Crystals.

One of them was a gray round bone that was about a foot long. It was hard and mottled. Other than a few gray patterns on its surface, it was almost no different from a normal Stone. One look and one could tell that it was an ancient object.

The other item was a pitch-black spirit flower that was the size of a bowl. There were blood-red spirit patterns on every petal, and when combined together, they looked like a creepy smiley face.

The last item was a bottle of grayish-white liquid. The surface of the liquid had a layer of gray flame-like light, but it emitted a bone-piercing chill that could be felt through the walls of the bottle. He did not know what kind of Spiritual Liquid it was.

However, the aura of these materials was completely different from normal spiritual materials. Han Li guessed that these were spiritual materials that could only be found in the Dust World.

After a quick look, he put away all the materials.

At this moment, there were only three items left on the ground. Two Immortal Equipment and a Black Jade Box.

One was a pitch-black spear. The body of the spear was simple and unadorned, but the spearhead was black and shiny. One could faintly see a red mark on it. It emitted a dense killing aura.

The other Immortal Equipment was a gray veil that was as thin as a cicada's wings. There were many star-like patterns on it that emitted a faint gray light.

Han Li bent down and lifted the black spear. His expression immediately changed.

The spear did not look big, but it was extremely heavy. It was almost as heavy as his Heavy Water True Wheel.

He exerted strength in his arm and lifted the black spear. Then, he shook his wrist.

Swish! Swish!

Three beautiful spear shadows appeared and pierced through the air before exploding.

The nearby void trembled and only calmed down after a while.

"Good spear!"

Han Li lightly praised. Then, with a thought, he poured the Immortal Spiritual Power in his body into the spear.

However, no matter how much Immortal Spiritual Power he poured in, it was like a clay ox entering the sea. The black spear did not react at all.

He raised his eyebrows and came to a realization.

The energy in a Rat Immortal's body was special. It was completely different from Immortal Spiritual Power. This black spear was probably a weapon that only a Rat Immortal could use. Since he was using his Immortal Spiritual Power, there was naturally no reaction.

A trace of regret flashed in his eyes. He waved the black spear a few more times and was about to put it away.

At this moment, a thin layer of black light suddenly appeared on the black spear.

When Han Li saw this, he could not help but be stunned.

When he waved the spear just now, he inadvertently poured the killing aura in his body into the black spear. He did not expect the spear to have a reaction.

"Could it be that killing aura can activate a Rat Immortal's weapon …" Han Li guessed. Then, he circulated the killing aura in his body.

Boom!

The accumulated killing aura in his body surged out and turned into a surging black fog that surrounded his body.

Han Li circulated the killing aura and slowly poured it into the black spear.

The black spear immediately emitted a bright black light. It was extremely deep and seemed like it could devour divine souls.

The blood mark on the spearhead shone brightly and released rays of blood-red light. The light spiraled around the spearhead and let out a sharp whistling sound. It was terrifying.

Han Li was surprised. His killing aura could actually activate a Rat Immortal's weapon.

However, it could only activate it. This black spear's quality was extremely high. Its power was far from this.

He waved his hand and kept the black spear. Then, he picked up the grey veil.

This item was soft to the touch. It was like a cloud that could not be touched. It was also as light as a feather. He did not feel anything when he held it in his hand.

Han Li looked at the item. Then, the killing aura in his body surged and poured into the grey veil.

The surface of the veil instantly became several times thicker. It emitted a layer of grey light. At the same time, ancient patterns appeared on the surface of the veil. They were completely different from ordinary spirit patterns and formation patterns. They looked like they were casually scribbled. However, they gave off a mysterious feeling.

The veil that became thicker gave off a feeling that it was soft yet hard. It was extremely tough.

Han Li nodded his head. It seemed that this veil was a defensive treasure.

However, at this moment, his gaze suddenly focused on the patterns on the surface of the veil. He was surprised.

The patterns on the grey veil looked familiar. It was as if he had seen them somewhere before.

"That's right!"

Han Li quickly recalled. He waved his hand and took out a silver jade box. After opening it, there was a soft grey item. It was the mysterious grey cloth that he had obtained from Xiong Shan.

He unfolded the grey cloth. There were some mysterious and ancient patterns on it. Although the patterns on the black veil were slightly different, the general style was the same. It was clear that they were the same type of spirit patterns.

"It seems that this grey cloth is also from the Dust World …" Han Li thought. Then, he tried to pour his killing aura into the grey cloth. However, there was no reaction from the grey cloth.

He raised his eyebrows. Could it be that he had guessed wrong?

Han Li muttered to himself. The black mist on his body immediately became thicker and continued to pour into the grey cloth.

Time passed bit by bit. In the blink of an eye, 15 minutes had passed. However, there was still no reaction from the grey cloth.

Seeing this, he could not help but wonder if he had guessed wrong.

After a while, there was still no reaction from the grey cloth. Han Li was a bit dispirited and was about to stop using his killing aura.

However, at this moment, the surface of the grey cloth suddenly shone with a layer of grey light. The color was so faint that it was almost invisible to the naked eye.

Han Li's eyes immediately lit up. He had guessed correctly.

He took a deep breath and used all his strength to activate the killing aura in his body and poured it into the grey cloth.

The light on the grey cloth immediately became brighter. The faintly discernible ancient patterns also slowly lit up. They gradually became clearer and quickly spread across the grey cloth.

However, no matter how much Han Li poured in the killing aura, the light on the grey cloth did not continue to brighten, and the ancient patterns did not continue to appear.

"It seems that the killing aura is not enough. I can only use it to this extent." He stopped, looked at the grey cloth twice, and put it away again.

This grey cloth was something that he had obtained by chance. Han Li did not pay much attention to it. It would be good if he could discover its secret, but it did not matter if he could not.

He immediately put away the grey veil and picked up the black jade box. There was a grey talisman on the box.

It looked like it was used for sealing.
