Chapter 668 Interrogation

The Ding brothers were moved to tears when they heard this!

"Big brother, thank you for letting us three brothers join. From now on, we'll follow your lead!"

"Big brother, we will definitely create a new era for the Night King Hall!"

"Big brother, please don't hesitate to command us!"

With the addition of the Ding brothers, the strength of the Night King Hall naturally climbed another level.

Everyone was excited, but just at that moment, a grating flute melody once again filled the air—

"Wu wu wu wu wu wu wu~~~~~~~~~"

The sound of the flute was steady, neither rushed nor slow, and the tune was eerie, making it very uncomfortable to listen to.

"Damn it!"

Ye Tian yelled outloud. He was very familiar with this sound—the sound that controlled people and turned them into puppets.

Once a martial artist was killed or defeated, he could be controlled by the Controller and turned into a puppet, and after becoming a puppet, their strength would be greatly increased!
