Ren Tianxing took a sip of tea before speaking, "It's not impossible for us of the Vermilion Bird Clan to regard Water Curtain Cave as the highest authority. However, most of our clan members are untamed and mischievous, difficult to control. Hence, the Green Emperor must offer something convincing to gain their allegiance."
Wukong sneered, "What do you want?"
Ren Tianxing nodded, "During the Middle Ages, in the period of The Investiture of the Gods, a traitor from our clan lost a Vermilion Bird Fruit in the Ancient Tomb. If the Green Emperor desires the Vermilion Bird Clan to honor Water Curtain Cave as supreme, then he should retrieve this Vermilion Bird Fruit from the Ancient Tomb first."
"The Ancient Tomb?" Wukong frowned, having never heard of this matter before.
