It definitely wouldn't do to let Siming and Guanshanhai actually fight. The impact of a battle between two immortals could be gauged from the clash between the Ninefold Immortal and Siming—the entire Extreme North nearly turned back into a sea of stars.
The same would apply to Siming and Guanshanhai. If those two immortals fought, the entire Ask Dao Sect would be caught in the crossfire... No, wait. Before that happened, Yun Zhi would lock them back up.
Still, the idea of suppressing the prisoners' cultivation and letting them move about freely was workable.
Take the Moon Laurel Immortal Palace's Light-Imprisoning Treasure Box, for example. Any cultivator inside the box had their cultivation suppressed to the same level. The Undying Fairy had even possessed herself and used the box to challenge the four sect leaders of the Five Great Immortal Sects.
The Light-Imprisoning Treasure Box certainly wasn't powerful enough to suppress immortals. But it shouldn't be a problem to ask the Heaven-Appointing Immortal to use its principles to refine a higher-grade immortal artifact.
After all, he was the founder of artifact refinement. Surely there was something he couldn't refine.
"Still, refining an immortal artifact capable of suppressing an immortal's cultivation would probably take quite a bit of immortal metal." Lu Yang pondered. He wasn't the Sect Master, but as a member of the Ask Dao Sect, he had to consider the sect's needs.

After learning how to undo the sun's seal, Yun Zhi wanted to take Lu Yang
