Chen Shi and Black Pot left the Heavenly Pond Capital, following the caravan from the Juxian Building to the Infinite Cliff.
According to Shao Jing, there is a weak point here connecting to another underworld. From here, one can reach the underworld corresponding to Qianyang Mountain, and from there, returning to the Mortal World becomes much easier.
The Red Mountain Hall built a bridge at this weak point, an arched bridge. One end stretches over the Infinite Cliff, and at the center of the bridge, the bridge body suddenly disappears.
But if you walk to the center of the bridge, just take one more step forward, and you'll find that you don't fall off the cliff but arrive at the other half of the bridge.
This half of the bridge crosses over a dry small river in the underworld, but it's still just half a bridge — the other half is completely invisible.
The construction of the bridge could be described as a masterpiece of craftsmanship.
