There is an emerald pool near the construction site. For thousands of years, no matter how much precipitation occurs, the water in the pool will never dry up or overflow. Legend has it that there is a dragon living inside.

What problems will Chi Yue encounter after traveling through time? Are there really dragons in the emerald pool?
If so, what does Chi Yue have to do with Long?...
