The Fourth Prince immediately reached out and took the heart from the female demon's hand.

"How can you touch my things?" The Fourth Prince said proudly.

In an instant, the Fourth Prince's surroundings released a murderous aura.

"Plop!"

The middle-aged demonic cultivator knelt on the ground and said, "Your Highness, this old servant is very loyal and has no other intentions."

"Don't worry, I still have some use for you. I'll not kill you." The Fourth Prince patted the middle-aged demonic cultivator's shoulder and then pointed at Ye Xiao before saying, "Kill him, then come and find me!"

"This old servant will do as you say!" The middle-aged demonic cultivator said respectfully and then looked at Ye Xiao ferociously.

The Fourth Prince left while laughing loudly. At this moment, his aura increased once again. He, who was originally in the Late Stage of Immortal Emperor Realm, had actually broken through and reached the Early Stage of Ancient Immortal Realm within the time it took for an incense stick to burn.

"Brat, are you going to kill yourself or wait for me to take action?"

After the Fourth Prince left, the middle-aged demonic cultivator's voice echoed throughout the cave.

According to him, the boy in front of him was definitely courting death. Seeing such a scene unfolding before his eyes, he must have been scared witless.

The middle-aged demonic cultivator's eyes flashed with contempt. He looked at Ye Xiao with disdain and took out a black talisman from the spatial ring. This black talisman was called the Thunder Wolf Kill Talisman.

After taking the talisman out, the middle-aged demonic cultivator threw it towards Ye Xiao.

"Rumble!" "BOOM!"

Explosions of thunder sounded one after another and a clap of thunder suddenly appeared in front of Ye Xiao.

In the midst of this thunderbolt, a gigantic thunder wolf appeared and fiercely pounced towards Ye Xiao.

Seeing this, Ye Xiao didn't panic. Instead, he took out the Sea Dragon Spear, held it horizontally in his hand, and stabbed forward with great force!

"Puff!"

The Sea Dragon Spear pierced in the head of a giant wolf formed from thunder. Although it was pierced by Ye Xiao's spear, it still didn't vanish.

The middle-aged demonic cultivator that was about to leave suddenly exclaimed and said after seeing all of these things happening: "You do have some ability after all!"

The middle-aged demonic cultivator flew back again while demonic energy shone on his body. For a moment, the aura of the Thunder Wolf Kill Talisman was completely released.The ground started to shake crazily. Ye Xiao's clothes were fluttering in the wind and his bones were also emitting "ka ka" sounds.

This Demonic Cultivator in front of him was actually a lightning attribute cultivator. More importantly, he had a lightning attributed body.

Ye Xiao's eyes lit up when he saw this. He suddenly used the Spirit Devour Escape and flew towards the altar behind the Demonic Cultivator.

"Still trying to escape!" Seeing that, the middle-aged demonic cultivator immediately chased after him. Just that, Ye Xiao's movements were extremely fast. With just a flash, he was already at the bottom of the altar.

He smashed his hand towards the altar, only to see that the stone altar had suddenly cracked into countless cracks and a hole had appeared on the altar. The inside of the hole was actually hollow.

"How could this be?" When the middle-aged demonic cultivator saw this, he was also taken aback. But just as he was in a daze, Ye Xiao had already flown to the side.

"Pfft!"

A jet black evil aura flew out from inside the hole and ruthlessly smashed onto the body of the middle-aged demonic cultivator.

The middle-aged demonic cultivator had the protection of the demonic aura on his body, but when he saw the black evil aura, the demonic aura on his body was suppressed before immediately exploding.

"Ka-cha!"

It was also the moment when Thunder Wolf completely lost all of its power and turned dull, finally dissipating in thin air.

Using the Divine Sense, Ye Xiao had already probed the altar previously and discovered that it still contained a trace of demonic power. With his current cultivation level, this power was still difficult to deal with.

Coincidentally, the middle-aged demonic cultivator wanted to kill him, so Ye Xiao didn't mind borrowing this blade to kill the demonic cultivator.

That heart which was taken away by the Fourth Prince, if Ye Xiao was not wrong, was only a part of the Blood Corpse's body. Whoever obtained that heart would have a drastic change in personality. It might even be controlled by the Blood Corpse and turned into a puppet.

"Who is disturbing my slumber!" A stern shout suddenly exploded in Ye Xiao's mind.

From the hole in the altar came a blood-red light. A dark red blood core was buried under a piece of flesh. With every beat of this flesh, the Blood Core would emit a strange, dazzling red light.

Ye Xiao then turned a deaf ear to the other party's voice and continued to walk in the direction of the Blood Core.

"How dare you!"

Suddenly, a phantom appeared out of the Blood Core. This phantom was erratic but its eyes were exceptionally clear. Its eyes were faintly emitting a bone-piercing cold light.

What was equally eye-catching was that the figure was actually wearing a blood-red robe.Ye Xiao's eyes became serious as he muttered, "A Demon? No, it looks different from an ordinary demon. No, it's not a demon, it should be something else. The aura around this phantom is simply too evil. And the moment it appeared, the infernal energy in the air inside this cave seems to be attracted by it and is being devoured by it quickly!"

The mysterious demon stared at Ye Xiao as if he had already seen through Ye Xiao and said, "Submit to me, I will bestow you with heavenly luck."

Ye Xiao did not react for a short while before asking back: "You can't even protect yourself, what power do you have to give me?"

The mysterious demon's power suddenly turned solemn and dignified. He said in a deep voice, "Submit to me and I'll grant you endless infernal energy!"

The blood and flesh around him as though they had obeyed the orders of the mysterious demon, immediately exploded, transforming into a blood mist that floated to Ye Xiao's side.

Ye Xiao did not hesitate and accepted them all. This ball of blood fog was filled with powerful vitality. After absorbing for a moment, Ye Xiao felt that his meridians were somewhat full.

"Is that all? It is not enough?"

There was some ridicule in Ye Xiao's eyes as he said this sentence to the demon's phantom that had suddenly appeared here.

The phantom seemed to be enraged after hearing Ye Xiao's ridicule. The entire altar also exploded as the blood energy gathered at Ye Xiao's side.

"Devour!"

Ye Xiao used his devouring ability as a small whirlpool appeared in front of Ye Xiao's chest and started spinning crazily.

The whirlpool then sucked all the blood energy into his body. Ye Xiao wanted to take this opportunity and cultivate the Fifth Layer of Nine Dragon Universal Circulation Technique but the time and place were not right. So, Ye Xiao chose to endure for a while more.

He simply used all the blood energy and infernal energy to strengthen his cultivation base.

"It's not enough!"

"Again!"

After continuously absorbing the blood mist three or four times, Ye Xiao still shook his head. He said, "With just this little thing of yours, you think it's worthy of being called great fortune? You can't even let me break through a single minor stage and you are calling it great fortune? If you want to find someone to submit to you, then go and find someone else."

Ye Xiao turned around and acted as if he was going to leave.

"Your fleshly body isn't bad. This is a drop of Ancient Demon's Blood that I refined in my past life when I was still alive and was not a Blood Corpse. I'll give this drop of blood to you."

From within the Blood Core, a drop of dark blood suddenly flew out, heading towards the center of Ye Xiao's brows.

"Whiz!"

The instant the drop of blood entered the space between Ye Xiao's brows, Ye Xiao's body trembled.

Ancient Demon's blood, what was that?

It was the first time Ye Xiao heard the name "Ancient Demon." He didn't know what an Ancient Demon was but he guessed that it should be the demons who have existed in the ancient era.

But when he heard the term "Ancient Demon", for some reason, a burst of anger, that appeared out of nowhere, suddenly affected his mood. Ye Xiao could tell that this anger came from the depth of his soul. It means the Ancient Demon must be related to the Divine Soul Emperor Dragon in some ways.

The anger he felt at this time was many times stronger than what he felt when he heard the term "Demon" for the very first time.
