The Thorn Bone Dragon ran desperately into the distance, but in terms of speed, Zaun had nothing to fear from its opponent.

He used the techniques of teleportation and shapeshifting alternately and quickly caught up with his opponent.

His fist, imbued with the purifying power of the Primordial Chaos Scripture, continued to fall relentlessly towards the opponent's head.

The special patterns on the Thorn Bone Dragon's body began to flicker erratically. As Zuan sensed that the opponent's rebounding force was getting weaker and weaker, he became more and more confident and punched with increasing force.

Finally, the special patterns on the Thorn Bone Dragon's body burst into a dazzling light, then became dim and lifeless.

At that moment, Zuan's fist landed on its head, its skull hissed with white smoke, and it let out a painful scream.

The primordial energy is extremely lethal to undead creatures!

"Big brother, I was wrong, please stop hitting me."

"Didn't you just tell me to hit you?"

"Brother, I was just being ignorant. I hope you will forgive my rudeness."

"But the way you were acting just now was so obnoxious, I can't stand not hitting you."

"..."

The two continued their pursuit, one fleeing and the other chasing. The Thorn Bone Dragon's speed decreased, and its pleas for mercy grew fainter.

"Big brother, I really can't take it anymore. If you hit me again, I'll really die."

"Then tell me why you refined that snow mountain before?" Zuan slightly reduced his strength, but did not completely relax, lest the opponent regain the rebound skill.

"Because the boss said these snow-capped mountains are the final barrier. As long as we refine them, he will have a way to completely break the seal," the Thorn Bone Dragon hurriedly replied.

Zu An's heart skipped a beat. He realized that the demons had progressed to this point and were about to completely break the seal: "Who is your leader?"

"The boss is the boss."

Bang!

The response was a fist the size of a sand bowl, which nearly extinguished the ghostly flames in its eye sockets.

It hurriedly said, "I've seen that snow woman before; she's the one who's glowing all over."

"Oh?" Zu An thought to himself, no wonder even the Snow Maiden couldn't see the other party's true face under the radiance. "What's your leader's name? How does his strength compare to yours and that scorpion from before?"

“I don’t know what the boss’s name is. I met him relatively late, so everyone calls him the boss. No one dares to call him by his real name,” Thorn Bone Dragon said. “As for his strength, all of us combined are no match for him.”

Zu An's heart sank. Could it be that the strength of that so-called boss had reached a level beyond description?

The mysterious tomb where he encountered Jing Teng contained many powerful beings whose names he did not even know, and the oppressive force they exerted on him was still vivid in his memory.

"So what skills does your boss have?" Zuan asked after thinking for a moment.

"Will you let me go if I tell you?" The ghostly flames flickered in the Thorn Bone Dragon's eyes.

“If the information you provide is indeed valuable, I can consider letting you go,” Zuan said in a deep voice.

"You swear?" The Thorn Bone Dragon was somewhat skeptical, feeling that his words were ambiguous.

“Okay, I swear.” Zuan readily agreed. He was quite good at these word games anyway, and had tricked many people back in the day.

Hearing that he had indeed sworn an oath, the Thorn Bone Dragon breathed a slight sigh of relief: "Then can you stop fighting for now? I'm really about to be burned to death."

The primordial energy has a strong burning and purifying power on undead creatures, so their current state is naturally unpleasant.

"The faster you speak, the less pain you suffer." Zaun didn't stop; he couldn't give this guy a chance to breathe.

“I’ll talk, I’ll talk, his ability is…”
