One-click Cultivation System

Su Lang immediately gave the order to the system, trying to upgrade the Nethersky Sword.    

However.    

The materials were still not enough!    

It was not that Su Lang had too few materials. It was because the Nethersky Sword required a lot of Advanced Level materials to evolve!    

"All the materials that can be synthesized have been synthesized. "    

"It's impossible to evolve the Nethersky Sword in a short period of time. "    

"Then, let me try to see if I can evolve other weapons?"    

"Five Elements Sky attributes, Space Magic Cube, White Jade Palace, and Winding Nether Mirror are all Support Defense Type Great Emperor Weapon. I don't need to upgrade them for now. "    

"Then I'll try the Heaven Killing Scabbards and Edgeless Hearts. "    

After pondering for a moment, Su Lang asked the system.    

In the end, he found out that the Heaven Killing Scabbards were only Seven Extremes Emperor weapons. In order for them to evolve to Supreme Imperial Weapon, they needed more materials, and he also needed a few more materials.    

Only a Quasi Supreme Emperor Level Edgeless Heart would require enough materials to level up.    

"Then I'll upgrade it into an Edgeless Heart. "    

"After Lin Gui uses his trump card, I'll decide whether to store the materials in the Evolution Nethersky Sword or use the Evolution Edgeless Heart now. "    

After making up his mind, Su Lang sent his Clone to monitor the place where Lin Gui disappeared.    

At the same time.    

At the bottom of the central area of Peerless House.    

A huge cave had almost formed a strange underground world!    

In this dark space.    

There were all kinds of strange plants growing here. They had incomparably wide leaves, and their leaves were glowing with a fluorescent light.    

If one looked closely, one would notice that these glowing veins actually had a vague shape of a dragon!    

And among these plants, there were also some spirit beasts.    

These spirit beasts were basically all snake shaped, and they also had some dragon characteristics. They looked to be a combination of fierce, elegant, and noble, and were very strange.    

Of course, there were also some creatures that weren't snake shaped.    

However, these 'other' creatures could only be reduced to the lowest level of food here!    

This was because those Dragon-Snakes that were shaped like spirit beasts were very powerful. Not only were there Immortal Level existences here, there were even Emperor Level existences here!    

These snake-shaped creatures were entrenched on some plants, rocks, and walls. The heads of these Dragon-Snakes were pointing in the same direction.    

Their mouths were wide open, as if they were absorbing something.    

Right at this moment.    

A stone fell.    

It turned out that Lin Gui had come to this underground space from the ground!    

Countless living beings in the shape of Dragon-Snakes prostrated themselves on the ground when they saw Lin Gui.    

This was because Lin Gui possessed a Dragonwillow Tao Embryo, and his cultivation base was very powerful. He had naturally created a terrifying pressure on these living beings who possessed extremely thin dragon veins.    

Lin Gui looked around him, but he didn't look at the Dragon-Snakes that were shaped like spirit beasts. After he identified his direction, he flew straight towards his destination.    

With the speed of a Quasi Supreme Emperor Level, he arrived at the bottom of a gigantic stone pillar in an instant.    

This stone pillar was extremely huge, and it looked like a heavenly pillar of this underground world. It towered into the sky and opened up this underground world.    

On top of the stone pillar. There were similarly dragon-shaped fluorescent patterns!    

And these fluorescent patterns were even brighter and thicker.    

The strange plants surrounding the stone pillar also grew taller and had more powerful spiritual pressure.    

He flew along the fluorescent dragon veins on the stone pillar.    

Lin Gui flew upwards and soon arrived at the middle of the stone pillar.    

This section of the stone pillar was already covered by a strange fluorescent light.    

Strands of fluorescent light flowed down from this section of the stone pillar, forming the dragon vein patterns below.    

This was the source of the strange fluorescent light of the entire underground world!    

"Master!"    

"Disciple has come to pay a visit to you!"    

Lin Gui faced the fluorescent stone pillar and knelt in the air. He transformed into a flowing light and rushed into the stone pillar!    

The tough stone pillar that contained a large amount of dragon marks and fluorescence automatically opened up in front of Lin Gui like soft mud, revealing the passageway.    

Following the passageway.    

Lin Gui arrived at the center of the stone pillar!    

This place had already become a sea of fluorescent dragon marks, and it was filled with dazzling light from all directions!    

In the center, there was a tall man with transparent flesh and blood floating in the air.
