Upper Realm and Lower Realm

The Ghost Pearl was the energy source of the King of Hell.

Once the Ghost Pearl was damaged, it had severe consequences for the King of Hell, comparable to a cultivator's spiritual root being damaged.

Therefore, unless necessary, no ghosts would choose to sacrifice their Ghost Pearl and use it as a magic item for the attack.

Only in the most dangerous situation would the Kings of Hell make such a risky move, which showed how much pressure Lu Yuan was putting on them.

Using the Ghost Pearl to attack was like the Kings of Hell's last-ditch effort to risk their own life.

The power of this attack was even comparable to the attack of a second transition Core Formation Stage cultivator.

However, just as the two Ghost Pearls were about to hit Lu Yuan's barrier, Lu Yuan also made a swift sword movement that looked effortless.

However, this seemingly effortless sword strike forced Shen Xuan to defend himself.
