Heaven-defying Upgrade System

"Fuck you... don't look around! Lao Tzu is right in front of you!" The voice called out anxiously, "Hurry up and get away!"

Liu Fei focused his gaze on the giant flame wolf and was taken aback for a moment, and said, "Can this giant flame wolf speak?"

"You're the **** wolf! Lao Tzu is the Black Flame Demon!" the voice exclaimed extremely unhappy.

"Black Flame Demon?" Liu Fei frowned and said, "What is that?"

The Black Flame Demon almost fainted, thinking about how noble and superior his identity was, but now it has become something...

"Lao Tzu is nothing..." The Black Flame Demon said angrily. He felt wrong when he said it, and immediately changed his words: "You humble cultivator, you haven't even heard of Lao Tzu's name. See if Lao Tzu refuses you... …"

"How?" Liu Fei blinked and asked.

"You let me out first," said the Black Flame Demon.

"Impossible!" Liu Fei said to him disdainfully, and finally sealed it with the Xuanbing Sword. How could he easily release it again?

The Black Flame Demon's voice changed, and an extremely seductive voice said to Liu Fei: "Young man, don't you want to get the treasure here? There are many good things in this cave. The Xuanming spar and The piles of treasures are only rare in comparison. Hey, how about making a deal? If you let me out, I will tell you where these treasures are hidden!"

Liu Fei came here to find the treasure, and he was slightly moved when he heard the news that there was a treasure. But it is dangerous to release this black flame demon and exchange news about the treasure.

After weighing it in mind, Liu Fei couldn't make up his mind.

"Don't worry, after letting me out, I will definitely not hurt you." Black Flame Demon said quack and laughed.

Liu Fei frowned. He couldn't fully believe what the Black Flame Demon had said. If it were released, the consequences would be hard to predict, and it would be impossible to control it by himself.

After thinking about it, Liu Fei decided to release it. After all, he could seal it once and seal it a second time. So sitting on the ground, he recovered the true qi in his body, then walked to the frozen ice layer, patted the ice surface, a chill came, and Liu Fei immediately danced the Tai Chi Green Rainbow Sword and shouted: "Tai Chi! Yin and Yang. reverse!"

A pair of Taiji pictures appeared in front of him, and a breeze blew across the firm ice layer. This wind was not an ordinary wind, blowing on the ice layer. In a short time, the firm ice layer began to melt.

In a short while, the ice has loosened.

"Roar……"

The flame giant wolves sealed inside let out a low roar, and with a blaze of flames on its body, the ice layer was completely shattered.

Liu Fei immediately withdrew and backed away, still holding the Tai Chi diagram in his hand, his eyes fixed on the giant flame wolf. If the Black Flame Demon dared not abide by the agreement, Liu Fei would immediately freeze it.

Then at this moment, the body of the flame giant trembles violently, and as a low roar sounded, the flame giant wolf suddenly fell to the ground with a bang. The flames on his body dimmed instantly.

At this moment, a black light rushed towards Liu Fei.

"Quack...for thousands of years, finally there is a human body that can be used!" The black light smiled gloomily, and in the blink of an eye, it plunged into Liu Fei's body.

Liu Fei's heart shuddered, he had no time to defend, so he was succeeded by this black light! Suddenly a bad premonition appeared in Liu Fei's mind, "Seize the house!" Liu Fei exclaimed. The purpose of this black light was to seize the house!

"Give me your body!" Black Flame Demon said with a smile: "Quack...Ah!"

Suddenly, the Black Flame Demon let out a scream.

"What is this!?" The Black Flame Demon roared: "It's an angry thunder hammer! Ah...no!"

After stepping into the spirit pill realm, Liu Fei tempered the rage thunder into his body as Yun'er said. If this black flame demon wants to seize Liu Fei’s body, he must first enter his purple mansion and destroy Liu Fei’s soul. But in that purple mansion, there are not only Liu Fei’s soul, but also An angry thunder hammer engulfed Liu Fei's eloquent pill.

The Black Flame Demon was anxious to take down Liu Fei's soul, but without observation, he rashly touched the angry thunder hammer. Although Liu Fei was not controlling the Fury Thunder Hammer, the Fury Thunder Hammer spontaneously sent out a ball of lightning and instantly hit the Black Flame Demon.

The Black Flame Demon suddenly suffered a dumb loss. He couldn't tell the pain, and hurriedly escaped from Liu Fei's body.

A cloud of black light fell in front of Liu Fei, the black light trembling up and down, the surface of the light leaping, it looked extremely uncomfortable.

Liu Fei immediately sacrificed the green sword and aimed it at the black light!

"No! Don't kill me!" Black Flame Demon screamed in shock.

Liu Fei sneered and said, "Give me a reason not to kill you!"

"As long as you let me go, let me do anything. If you violate it, let me thunder and thunder!" The Black Flame Demon hurriedly called, "I can swear to you!"

Liu Fei was stunned for a moment. The heart oath is not played casually. As long as the heart oath is taken, it is monitored by the heavens. If the person who swears violates the oath, he will surely suffer a real damnation.

When Liu Fei was stunned, the Black Flame Demon had already vowed, and a drop of black light flew in front of Liu Fei. Liu Fei closed his eyes slightly and thought, since he made a vow, he will no longer threaten himself. Simply, Liu Fei put the crystal of the pledge into his body.

At the same time, Liu Fei also learned part of the memory of the Black Flame Demon.

This guy is actually a big demon. Two thousand years ago, because he offended a big man, he was almost killed by that person. He fell into this Zhentian Mountain and his body was destroyed, leaving only a fragile soul. Because the Black Flame Demon was born with extremely strong fire attributes, under the influence of the soul, this area gradually became a land of lava.

The Black Flame Demon didn't dare to leave this area without a physical body, and had never seen the outside world.

That flame giant wolf is the body that his primordial spirit cultivated using the flame essence and temporarily used for the primordial spirit to board. It has its own consciousness. After the black flame demon left, it became an independent existence. At this time, it turned into a wolf pup the size of a puppy, with its hair flowing like flames, lying with its eyes closed. On the ground, it seemed to be asleep.

"Where is the treasure?" Liu Fei asked.

The Black Flame Demon didn't dare to deceive Liu Fei, for fear of being condemned, so he said: "Come with me, I won't use those things anyway." The Black Flame Demon is now in the state of primordial spirit and can use very few things. So he took Liu Fei to look for the treasure very calmly.

A cave hidden behind magma is extremely hidden. If it weren't for the Black Flame Demon to control the fire magic, ordinary people would not be able to pass this magma. After the magma separated towards the two sides, a hole appeared in front of the two of them, and a strong spiritual force radiated from the hole.
