Chapter 278: Promotion to the Fourth Stage Pill Master, A Tribulation Treasure Pill, Nine Heavy Pill Tribulations_4

"However, up until now, it seems that you, My Lord, have had no need for any array master to help with the maintenance,"

Lin Yazhu looked curiously at Zhou Sui.

Because normally, Nascent Soul powers that wanted to maintain their own Fourth Stage array formations needed an array master to help, constantly monitoring each array point to prevent any accidents from happening to the array.

If an accident or damage occurred, it would be repaired immediately.

Otherwise, the array is easily vulnerable, leading other cultivators to solve it.

But in this Xuan Yin Heavy Water Array, from beginning to end, only Zhou Sui himself maintained it.

Not requiring any other array master to get involved, it truly was unthinkable.

"Well, that naturally is a secret,"

Zhou Sui gave a slight smile. He wasn't planning to explain, as he didn't need to explain everything to his partner. Having a bit of mystery wasn't a bad thing.
