Shi Feiyang brought Jiang Shu to Yellow Mountain and found a place called the Purple-Gold Rapids.
A long stream flowed down from the mountain here, its water crystal clear. Strange rocks and green pines crowded both banks, dotted with flowers of every kind. Birds chirped in flocks, and the scenery was exquisitely peaceful and beautiful.

The Jade-Cutting Hook lay beneath the spring feeding the Purple-Gold Rapids. Shi Feiyang used the Two-Ideas Needles, the second-longest needles on the Disc Mechanism, to project Two-Polarity Magnetic Essence Qi and probe its location. The hook lay more than three thousand zhang underground, and retrieving it would take some effort.

Jiang Shu came up with a solution. "We could use
