Heaven-defying Upgrade System

Liu Fei estimated the distance of the chasm. Even the nearest place was about four or five hundred meters wide. Apart from Liu Feizhi, the rest of them had no way to cross it. Liu Fei knew in his heart that the treasure on the treasure map was... It was right across the chasm, and there was a bad feeling shrouding Liu Fei's heart. There seemed to be a powerful thing in front of him, and it was very dangerous.    

    

"You all wait here. I will go and investigate the other side. If you don't come back in two days, you guys can go back to Fenglong Town. In these two days, Gao Yuming will lead the team. You guys can decide what you want to do. You can find more Demonic Beast to practice with." Liu Fei instructed.    

    

"Big brother, let me go with you!" Zhang Dashan said worriedly.    

    

"No, I have a feeling that the other side is in danger. You guys can't handle it." Liu Fei said.    

    

Gao Yuming nodded and said, "Boss, you have to be careful." He wasn't worried about Liu Fei, because after witnessing Liu Fei's strength, Gao Yuming already had a plan in his heart, even if Liu Fei couldn't defeat him. Liu Fei's speed was the fastest amongst all the cultivators he had seen.    

    

He didn't know that Liu Fei had the title of 'Movement Speed Boost'.    

    

Liu Fei stood at the edge of the ravine and looked down. It was so deep that he couldn't see the bottom. It was pitch black. If he fell down, he would definitely be smashed to pieces. Without looking at it any longer, he stepped onto the Flying Sword, and with a flash of light, Liu Fei's figure quickly disappeared in front of Gao Yuming and the others' eyes. In the blink of an eye, he had crossed the wide ravine and disappeared into the faint fog on the opposite side.    

    

After arriving at the opposite side, Liu Fei immediately took out the treasure map. Before completing the exploration mission, he decided to first find the treasure recorded in the treasure map. According to the symbol on the treasure map, Liu Fei compared the surrounding environment. He slowly searched for the target point.    

    

Finally, Liu Fei came to a mountain wall. The target marked on the treasure map was here, but he did not continue forward.    

    

Liu Fei frowned and pressed his palm on the mountain wall in front of him. Suddenly, a golden light flashed and a roaring golden dragon rushed towards the mountain wall. "With a loud bang, the mountain wall was broken and crushed rocks fell down. One! A pitch-black hole appeared in front of Liu Fei.    

    

"Another hole?"    

    

Liu Fei felt slightly uncomfortable in his heart. The last time he entered the cave, he almost died inside. This time, he had to go into the cave again. Who knew what was waiting for him inside?    

    

However, Liu Fei was still envious of the treasure inside. Besides, his strength wasn't comparable to the one in the three-zhang yellow tomb. Even if he encountered danger, he would still be able to escape in time.    

    

Thinking of this, Liu Fei no longer hesitated and went straight into the cave.    

    

A ball of fiery light was raised from his palm. The flame was swaying in the long tunnel. Liu Fei went deeper and deeper into the tunnel. He estimated that he had gone about two or three thousand meters deeper, but he still couldn't see the end of the tunnel. However, after passing through this place, he didn't encounter any dangerous monsters.    

    

As Liu Fei continued to go deeper, the ground under his feet started to tremble slightly, and the temperature in the tunnel started to rise. Unconsciously, Liu Fei's head was covered in sweat.    

    

Furthermore, as he went deeper and deeper, Liu Fei vaguely heard the low roar that came from the Heaven Trembling Ridge when he first arrived.    

    

He didn't know what was waiting for him in front of him, so Liu Fei could only take precautions. He put the Gold Feathered Coat on his body, and the Rainbow Sword surrounded him, protecting him.    

    

As he walked, a bright light suddenly appeared in front of his eyes.    

    

Liu Fei's spirits were lifted. He was finally about to reach the end. However, he was even more cautious. When he approached the end of the light, he slowed down his pace and tensed up. He carefully checked his surroundings to see if there was any danger.    

    

Except for the increasingly high temperature and the faint roar, Liu Fei did not feel anything else.    

    

"Gulp, gulp, gulp..."    

    

When Liu Fei approached the bright light and walked out of the end of the tunnel, a wave of heat suddenly hit him.    

    

Liu Fei was shocked to find that he had already arrived at a huge underground cave. The cave was filled with boiling golden magma. The sound of it flowing was just like the deep roar of the beast.    

    

"How could this be?" Liu Fei thought in surprise. They had just entered the cave from the outside. According to the perpendicular height of the ground, this place was only a few hundred meters deep. How could there be a layer of magma here?    

    

Liu Fei was very confused. He could not figure out why. He might as well not waste his time guessing. Finding the treasure first was the most important thing. After making the necessary preparations, he carefully walked through the spatial zone. He had to be careful. There was a lot of magma here, and the temperature was extremely high. It was as if he had walked into a big furnace. Moreover, if he wasn't careful, if he wasn't careful, he might fall into the magma.    

    

Looking at the boiling magma, Liu Fei didn't dare imagine what the consequences would be if he fell into it.    

    

"This is?" Liu Fei suddenly realized that there was a stone wall behind the flowing magma. There was a small group of black and gold stones. The surface of the stones was emitting a faint colorful glow. It was really beautiful. Furthermore, Liu Fei could feel that these black and gold stones... It contained extremely heavy spiritual energy.    

    

He didn't know what this thing was, but it didn't seem like it was an ordinary item. Liu Fei wanted to take the black and golden stone down. He controlled the Rainbow Sword to fly over and use the sharp edge of the sword. He cut open the ordinary rock beside the black and golden rock. The Rainbow Sword indeed did not disappoint him. It cut open the ordinary stone like cutting tofu. Then, under Liu Fei's control, it followed the cut rock. It went deeper and deeper, and revealed one side of the black and gold rock.    

    

Next, Liu Fei tried to use the Rainbow Sword to pry open the blackish-gold rock.    

    

Along with a series of cracking sounds, the blackish-gold rock attached to the ordinary rock loosened under the power of the Rainbow Sword, making a cracking sound as it fell off the rock.    

    

"Hua..."    

    

A wave of crushed rocks fell and rolled into the boiling lava. They were immediately wrapped and melted by the lava, emitting black smoke. The black metal also fell off and fell into the flowing lava with a bang.    

    

Liu Fei was slightly shocked.    

    

The magma didn't melt the black golden stones. It seemed like the material of the black golden stone was quite solid.    

    

However, how should he retrieve the black gold stone that fell into the magma?    

    

It was already too late for Liu Fei to think about it. If the black gold stone fell into the magma pool, who knew where it would run to? It would be too late to fish it out.    

    

Therefore, Liu Fei hastily controlled the rainbow sword to support the black golden stone. The rainbow sword shone brightly. A rainbow light spread out, successfully holding the black golden stone in the magma. However, this was an unusually hot feeling that spread to Liu Fei's body. The high temperature of the magma... It actually used the Rainbow Sword to attack Liu Fei's body.
