Kapitel 1665: A Day Like This Every Year (3)

Without a level nine spiritual power, how could the mermaid kidnap Lan Waihu with the Ground Drilling technique?

"Aqua Drilling", said Di Fuyi.

The three of them immediately looked at him.

Di Fuyi added, "The mermaids are very good at Aqua Drilling. As long as there's water underground, they can escape with anyone."

Yan Chen and Lan Yue looked at each other. There must be water underground; however, they could not follow the mermaid because they never learned Aqua Drilling.

Gu Xijiu paused and realized that she knew the Aqua Drilling technique. After all, she had Lan Jingke's memories in her head. However, the water flow underground was very complicated with multiple branches; hence, she could not find Little Fox's aura nor the mermaid's even though she could go underground.
