The ancestor who survived the tribulation was reborn and went to college

He quickly approached the Demon King, and the long sword in his hand turned into a white light, stabbing the Demon King's vitals.

The Demon King was unable to dodge and was cut deeply by Zhang Fan's sword energy.

It let out a roar of pain, and its body shuddered, but it quickly recovered.

The demon king's eyes widened in anger, and its body began to emit a black smoke, and the entire valley was shrouded in darkness.

Zhang Fan felt a strong pressure coming towards him, and his body seemed to be oppressed by a huge mountain, unable to move.

But Zhang Fan did not flinch. He held the long sword tightly in his hand, and his whole body emitted a dazzling light.

He waved his long sword and slashed at the demon king. The sword light was bright, like a bolt of lightning piercing the dark night sky.

The demon king let out a scream, and its body was cut with wounds one after another by Zhang Fan's sword energy.

Blood spurted out, staining the entire valley red.

The demon king felt that its power was rapidly being consumed. It roared, turned into a black light, and tried to escape from the battlefield.

Zhang Fan sneered, his body turned into a white lightning, and quickly caught up with the Demon King.

His long sword pierced the demon king's body, completely defeating it.

The demon king let out a scream and his body shook violently. He felt threatened by death and knew that he could no longer escape.

The demon king was defeated, and Zhang Fan stood on the battlefield, with the aura of cultivating immortality filling his body.

In his hand he held a sword that shone with golden light. The sword was engraved with ancient runes, exuding a powerful force.

The demon king's original arrogance was gone. He was lying on the ground in a mess, with blood dripping all over his body.

His eyes were full of fear and unwillingness. He never thought that he would be defeated at the hands of an immortal cultivator.

Zhang Fan looked at the Demon King indifferently. He knew that the Demon King no longer had the ability to resist.

The Demon King stared at Zhang Fan, his heart filled with shock and awe.

He is the ruler of the demon world. With his powerful strength and wisdom, he conquered countless demon clans and became the supreme being of the demon world.

However, during the fight with Zhang Fan, he realized his own insignificance.

Zhang Fan's cultivation far exceeded his imagination.

His swordsmanship is like a meteor from the sky, so fast that it is difficult to catch.

Every time he swings his sword, it can bring up a violent storm and turn the demon king's attack into nothing.

And his movements were extremely agile, as if he were moving instantly, making it impossible for the Demon King to capture his figure.

Zhang Fan slowly walked towards the Demon King, holding a sword with a cold light in his hand.

The sword is engraved with various runes, exuding a powerful force.

The tip of the sword gently touched the Demon King's throat, and a trace of blood dripped down the blade.

"Demon King, your arrogance must eventually end." Zhang Fan's voice was cold and firm.

Seeing that the Demon King did not speak, Zhang Fan said in a low voice again: "Demon King, you have been defeated. Now you have only two choices, either become my slave or die."

The demon king's body trembled slightly, knowing that he had no way out.

The Demon King raised his head with difficulty, his voice trembling: "Immortal cultivator, you have won. I am willing to surrender to you. I just ask you to spare my life."

It lowered its head and tail, indicating that it was willing to become Zhang Fan's slave.

Zhang Fan stood in front of the Demon King with firm and calm eyes.

He knew that only by signing a soul contract could he truly subdue this demon king, bring him under his command, and obey his orders unconditionally.

He slowly stretched out his hand, and a faint light appeared on his palm.

The Demon King's eyes moved slightly, as if he noticed the light in Zhang Fan's hand.

Its body trembled slightly, but soon regained its composure.

It does not want to be bound by human immortal cultivators, but the situation in front of it seems to be irreversible.

Zhang Fan took a deep breath, concentrated his mind, and began to recite the incantation of the soul contract.

His voice was low and powerful, like a whisper from the abyss.

The spell contained endless power, which gradually penetrated into the depths of the demon king's soul.

The demon king felt the power from Zhang Fan, its body trembled again, and a trace of pain flashed in its eyes.

Its soul seems to be bound by an invisible bond from which it cannot escape.

Zhang Fan's voice became louder and louder, and the power of the spell became more and more powerful.

His palms trembled slightly and sweat dripped from his forehead, but he did not stop.

He knew that only by persisting could he successfully sign the soul contract.

The demon king's body trembled violently, and its eyes were full of struggle.

Finally, Zhang Fan's voice reached its peak, and the power of the spell also reached its peak.

He raised his palm suddenly, and a powerful light spurted out from his hand and shot straight into the sky.

The light enveloped the Demon King's body, completely enveloping it.

The demon king's body twisted violently and let out a shrill howl.

As the light dissipated, the demon king's body gradually became illusory, and finally turned into a ray of light and shadow, blending into Zhang Fan's palm.

Zhang Fan felt the demon king's soul merge with his own, and he knew that he had successfully signed a soul contract.

The Demon King will always obey his orders and become his loyal comrade-in-arms.

The Demon King felt a powerful force pouring into his body, and his body began to change.

The original characteristics of the monster gradually disappeared, replaced by the human form.

He became a tall man, dressed in rich robes and with a crown on his head.

"From now on, you will be my subordinate and work for me." Zhang Fan's voice was full of majesty.

The Demon King knelt on the ground and replied in a low voice: "Yes, Master. I will do my best to serve you."

Zhang Fan nodded, knowing that the Demon King's power would be a huge asset to him.

Zhang Fan smiled slightly, put away his sword, then stretched out his hand and gently stroked the Demon King's head.

He didn't want to kill the Demon King, otherwise Zhang Fan wouldn't have been dealing with the Demon King for so long.

He knew that the Demon King's strength had been defeated by him, and it would be unnecessary to kill him again. He put away his sword, took a few steps back, and gave way to a way out.

"Demon King, you can leave here, but you must promise me one thing." There was a hint of majesty in Zhang Fan's voice.

The Demon King hesitated for a moment and finally nodded, knowing that he had no choice.

"Integrate all demon clan forces and obey my orders in the future." Zhang Fan's voice was firm and stern.

The Demon King lowered his head, knowing that this was his only choice.

He realized Zhang Fan's power. Zhang Fan was far more powerful than the demon clan. If he continued to fight against Zhang Fan, the demon clan would only perish.

What's more, he has already been given a soul contract by the other party and cannot resist.

"I promise you." There was a hint of helplessness and sadness in the Demon King's voice.

Zhang Fan nodded, knowing that the Demon King would be a good help for him to regain this small world in the future.
