Sinkhole Hunting Dragon (2023)

In Guangxi province lies the Eye of the Underworld, a massive sinkhole steeped in legend as a gateway to the realms of Yin and Yang. Rumor holds that the ancient book "Long Guan Lu," containing unusual recipes from bygone eras, is hidden within its depths. A decade ago, an expedition led by exploration expert Zhang Xiaotian perished there. Ten years later, Zhang Xiaotian’s son, Zhang Feng, receives a mysterious package, and the story begins to unfold.
