"Oh~~~!"

The totem thunder leopard let out a long howl, turned around and prepared to escape from this horrible place, galloping towards the Qinling Mountains.

Return to the ancient capital? What would he do if he went back? Would he wait to be surrounded by the ghosts of the local monarchs and attacked by them?

"Damn, why are you running towards the Qinling Mountains instead of going to the ancient capital?" Xu Mu looked confused. So, this totem thunder leopard was summoned from thousands of miles away just to take him away from here?

"boom!"

Suddenly, a huge flesh-mound corpse fell from the sky and smashed heavily in front of the totem thunder leopard, crushing a group of undead.

Immediately afterwards, behind them, the undead spirit that was as big as a mountain - the Mountain Corpse, let out a deafening roar.

The sound was like a shock wave, spreading in all directions. The air visible to the naked eye was vibrated, forming visible ripples.

"Damn it, the mountain corpse has noticed us." Xu Mu quickly lowered his head, dodged the attack of an undead skeleton, and shouted loudly: "Go back to the city quickly, you can't escape."

However, the Totem Thunder Leopard did not listen to Xu Mu's words. It changed direction and continued to escape. This place must be left as soon as possible.

"Howl!!!"

The originally bright sky suddenly turned gloomy. The Lord of the Underworld flew over their heads and quickly flew to the front. A powerful black energy shock wave gathered in his mouth, and he attacked the totem thunder leopard without hesitation.

The totem thunder leopard sensed the danger and quickly stabilized its body, firmly grasping the ground, and wisps of black lightning began to flash around its body.

As time went by, the lightning became more and more dense. In just a moment, all the undead in the surrounding area were wiped out. The totem thunder leopard was also completely covered by the black lightning, turning into a majestic and terrifying black thunder leopard.

The black lightning exuded an unsettling aura. The totem thunder leopard opened its mouth, revealing sharp fangs. Lightning began to gather in its mouth, gradually forming a huge thunder ball.

Xu Mu was not unfamiliar with this move. At the beginning, the Totem Thunder Leopard used this move to instantly kill the majestic bone minister of the commander-in-chief level. As a result, he also obtained a piece of intact undead crystal.

However, facing a monarch-level attack, would this trick really work?

You know, the power of the Lord of the Underworld even surpasses that of the Tyrant Ghost.

Soon, time gave the answer.

The black thunder ball and the black shock wave collided violently in the air. The explosion was deafening and magnificent. The entire ancient capital seemed to have encountered a major earthquake. All the buildings, including the city walls, were shaking constantly.

The source of this vibration was the duel between two monarch-level undead in the air.

"Roar~~!"

The totem thunder leopard let out a low roar, and a strong murderous intent was revealed in its white eyes. The black lightning around its body became more and more dense.

The Lord of the Underworld was also not willing to be outdone and roared, and the three heads emitted a black shock wave together.

The collision between the shock wave and the lightning ended in a tie.

"Brother Bao, can we go back to the city wall? The other Undead Lords are moving this way. If you don't go back, you won't just be facing the Mountain Corpse and the Underworld Lord next."

Xu Mu released his telekinesis to protect himself. The aftermath of the battle between the two monarch-level undead was simply not something a fragile mage like him could withstand.

The undead near them had already died in the aftermath of the first wave of battles. He was still safe and sound until now, all thanks to the protection of the Totem Thunder Leopard. The Totem Thunder Leopard ignored Xu Mu, or rather, it simply had no time to answer Xu Mu now. It had to divide its attention to protect Xu Mu while fighting with the Lord of the Underworld, which made it have no time to pay attention to Xu Mu.

It also wants to retreat back to the city now, but if this shock wave is not resolved, once it stops, not only will it be injured, but Xu Mu will definitely not survive.

Xu Mu also realized that the problem now was not whether he could go back, but that he would not be able to escape unless he injured the Lord of Haisha.

"What is that... Undead Crystal?"

Xu Mu noticed that there was a bone in the heart of this undead lord made up of a skeleton, and on that bone, there was an undead crystal embedded.

Although his Silent Thunder Death Light has reached super-level power, this is only the basic super-level power. The average super-level magician starts with an elemental soul seed.

In other words, the super-class magic released by a super-class wizard like Zhu Meng is actually four to six times stronger than Xu Mu's high-level magic that can rival the super-class.

All super-class mages with elemental souls have to join forces to fight against the monarch-level undead. His super-class magic is four to six times weaker than the previous one, so it is almost impossible for him to severely damage the monarch-level undead.

But if you attack the undead crystal, that’s another matter.

"Heavenly Punishment - Silent Thunder Death Light!"

Xu Mu did not hesitate and immediately constructed a complete thunder magic constellation. Countless purple-red lightning bolts were compressed into a beam of light only the size of a fist.

He seized the opportunity and decisively shot the fist-sized beam of light at the undead crystal of the Lord of the Underworld.

The perception of monarch-level creatures is so powerful that every move of Xu Mu is perceived by the Lord of the Underworld. It also knows that Xu Mu's silent thunder death ray is aimed at its own undead crystal.

But it ignored the attack. The undead crystal was protected by its hardest bones. As the king of skeletons, its bones were so hard that even super-level magic might not be able to destroy them.

Not to mention, this attack of magic, if it remembered correctly, should be a high-level magic of humans. In its perception, this was indeed a high-level magic.

One of its heads glanced at Xu Mu with disdain, and then continued to fight with the Totem Thunder Leopard with the other two heads.

The Lord of the Underworld was not unprepared. He mobilized the bones at the heart position and used all the bones to surround and protect the undead crystal.

Arrogance is arrogance, but no one would joke about their own life and safety, not even the dead.

The speed of the Silent Thunder Death Light was extremely fast. It arrived in front of the Lord of the Underworld in an instant, and then hit its chest, hitting its hardest bone.

"Something's wrong!"

The body of the Lord of the Underworld suddenly stiffened, and its bones were actually shattered! The bones that protected its undead crystal, the hardest bones in its body, were actually shattered!

No, to be more precise, it was not shattered, but after coming into contact with the lightning, that part of the bone actually disappeared!

This purple-red lightning has the ability to annihilate everything, whether it is elemental particles, dead air, space structure, or even its bones!

Although this annihilation power is weak, and its bones are extremely hard, the lightning can only annihilate its bones slowly.

But this means that the opponent's attack can ignore its defense and directly damage its undead crystal!
