They fall into an underground palace. As there is no food and water, they give up all their hopes and have sex. They are exhausted and luckily YEUNG finds some water. As there is a moth, CHI is certain that there is an exit. YEUNG opens an exit with his Sacred Sword. CHI's grandfather and mother arrive. YEUNG kills them as he thinks they want to hurt CHI. CHI is in deep grief. CHI cannot stay with YEUNG who has killed her relatives. She leaves secretly. CHING impersonates CHI and pretends to be chased after by foxes. YEUNG saves her.
