"I'll tear that Gu guy to pieces right now. Just you wait and see. I've almost recovered, and dealing with that kid will be more than enough for me," the fat man said confidently.

"Fatty, you have to be careful. Don't underestimate your opponent," the skinny man said with a hint of worry and a serious expression.

"Don't worry, just watch," the fat man confidently assured, patting his chest.

"You brat, since you're so ungrateful, don't blame me for being ruthless," the fat man said disdainfully and arrogantly.

After he finished speaking, a spear appeared in his hand. The spear was made of some unknown material, and it was extremely sharp. Its color was jet black, like coal. Even a wisp of aura emanating from it made people feel that it was extremely sharp and terrifying.

With a wave of his arm, a terrifying pressure erupted and raged forth. The vast and terrifying aura was like an eternal light, filled with overwhelming killing intent, roaring and surging.

"Boom!!!"

Under this terrifying fluctuation, the void was about to collapse, shattering like a mirror, cracking layer by layer, extremely frightening. He moved with lightning speed, fiercely stabbing towards Gu Changqing.

Seeing this, Gu Changqing smiled faintly, his heart calm and unperturbed, not taking it to heart at all. He stood there motionless, letting the fat man's spear pierce through him.

With a "thud," the fat man's spear seemed to hit some incredibly hard steel. He was taken aback, thinking he had stabbed the wrong thing. He looked bewildered and incredulous, and quickly opened his eyes to see what had happened.

When he looked closely, he could clearly see that when the spear pierced the opponent, it couldn't even bend a single hair on the opponent's body, but the spear tip was directly bent by a single hair on the opponent's body, sparks flew everywhere, and then the spear tip exploded into pieces with a crackling sound, collapsing into pieces!

Then, due to inertia, he was violently blasted away by Gu Changqing, flying several meters away before crashing heavily to the ground with a thud, spitting out a mouthful of blood.

"My God, I'm a Celestial King level expert! I didn't even manage to scratch a single hair on this guy's head. Could it be that he's cultivated some kind of indestructible body? His physique is so incredibly strong and frightening, it's truly terrifying." The fat man was completely bewildered and confused, secretly speculating in his mind.

The fat man was extremely surprised. He never expected that his all-out attack would not even break a hair on the opponent's head. He not only lost face but also suffered the consequences of his own actions.

My God, how could this be? This person is perfectly fine, without a single problem. No, this can't be, there must be some mistake.

Not only was the fat man in disbelief, but the skinny man next to him also looked bewildered and at a loss.

Although he had long anticipated that this person was not as weak as he appeared, he never expected Gui to be so terrifying. The fat man hadn't even managed to knock a hair off the man's head. It was unbelievable and shocking.

At this moment, Gu Changqing was still standing there quietly, looking at the fat man's disheveled appearance with a half-smile.

"Your confident and arrogant demeanor just now made me mistakenly believe you were incredibly powerful, but is this all? Is this all the strength you have? You didn't even manage to strike a hair on my head. This has truly broadened my horizons. You are far too weak." Gu Changqing stroked his chin and said with amusement.

"I don't believe it! How did you suddenly become so powerful? You must have taken some kind of cultivation-enhancing pill beforehand to defeat me like this. I'm not convinced! Let's fight again! This time, I'll definitely beat you to a pulp!" The fat man remained stubborn and refused to admit defeat.

"Heh, you weaklings are all the same, can't you accept defeat? If that's really the case, then you're truly despicable," Gu Changqing said bluntly, his face full of indifference and sarcasm.

"You brat, you're too arrogant and domineering, looking down on everyone! Do you think I'm a pushover if I don't show my power?" Upon hearing this, the fat man felt a surge of anger and said furiously.

He had never been ridiculed or looked down upon in public before. He was a dignified Immortal King, a powerful figure in the Demon Clan, a being above all others, who could command the wind and rain and had whatever he wanted. No one had ever dared to speak to him like that. If anyone had dared to speak to him like that, they would have been smashed into a pool of blood mist long ago.

To teach this brat a lesson, the fat man decided to use his trump card: an incredibly powerful elixir. This elixir was a special reward from above for his good performance, and it was extremely precious. Even the skinny man who was traveling with him didn't have one. He usually kept this elixir hidden away, treating it like a treasure, and never showed it to anyone.

It is said that eating it can instantly and forcibly raise one's cultivation level to the level of an Immortal Emperor. It is extremely powerful and awesome, but its only weakness is that it can only be maintained for a quarter of an hour. However, he felt that this time was enough for him to kill someone at will.

Immediately afterwards, he took out the elixir from his waist and swallowed it in one gulp.

The next moment, a powerful force surged through his body, finally erupting at a certain moment. The world was in turmoil, with sand and stones flying and strange phenomena appearing. It seemed as if the aura of an immortal emperor was about to burst forth.

"Boom!"

All the meridians and veins in his body were opened up, and there were no more shackles or fetters. His aura soared, and he directly stepped into the true Immortal Emperor realm!

"Hahaha, I'm an Immortal Emperor now! Let's see how you can still defeat me. I'm going to tear you to pieces right now!" The fat man laughed wildly and said excitedly.

"Immortal Emperor, not bad, not bad, impressive, but I think he's still a bit weak," Gu Changqing said with a faint smile.

"What? You're too arrogant, kid! Today I'll show you just how powerful an Immortal Emperor is!" the fat man said angrily.

After the fat man finished speaking, he immediately unleashed his Immortal Emperor-level cultivation, throwing a punch that caused a burst of airflow. A terrifying shockwave, like a tornado, gathered between his palms and fingers, creating a dreadful gust of wind that sent chills down everyone's spines as it slammed fiercely towards Gu Changqing.

"Well done." Gu Changqing sneered, unhurriedly using his finger as a sword to slash out.

In an instant, a flash of cold light appeared, like a celestial being descending from the heavens. The sky was instantly cleaved open, creating a crack hundreds of millions of feet long, revealing the dark wormhole behind it. Chaotic turbulence raged, terrifying beyond compare.

"Boom!"

In an instant, their attacks collided violently, and a deafening explosion rang out. Gu Changqing's palm slammed into the fat man's arm, instantly turning it into a shredded mess. Then, a large hole was punched in his chest, and blood gushed out, a horrifying sight!
