Chapitre 721: 230. Nail clipper box

"Jarvis, we're about to enter the Blue Cave."

Hadley Grant tightened the rope on his waist, ensuring that he and Noland Lee were firmly connected:

"Don't forget about the undercurrents I mentioned. The paths inside the Blue Cave are complicated and undercurrents are everywhere. If you encounter an undercurrent, hold the rope tight and don't get swept away."

As Hadley continued talking, he slapped his head:

"Oh, right, you can use the 'Deep Sea Swimming' spell, so you can practice it in the Blue Cave. The sooner you get familiar with this spell, the less likely you'll be in danger when encountering undercurrents."

"Alright, let me give it a try." Noland drew the blueprint of the "Deep Sea Swimming" spell in his mind.

A layer of dark blue magic light emerged on his body.

The brightness of the light weakened, and then turned into a thin blue water membrane on the surface of his body.

'Deep Sea Swimming' was successfully cast.
