Zhong held a grand banquet at his luxurious villa, and Shi caused a lot of laughs mingling with the guests. Zhong showed off his recently acquired Tang dynasty royal treasure - a gem-encrusted urinal, to flaunt his wealth.

Zhong and Anna each hired assassins to target Shi, but Shi remained unaware that his life was in grave danger...
