Digging Tunnels in the World of Sea Voyages, and the Celestial Dragons Are Stunned

After transmigrating into the world of seafaring, I accidentally entered God Valley.

The Celestial Dragons' hunt is about to begin.

Powerhouses like Rocks and Roger are closing in together.

Conqueror's Haki is everywhere, Observation Haki is as common as dogs, and Armament Haki is only good for taking a beating.

How can Luya, a lowly slave, protect himself?

While everyone else sails the seas, I dig tunnels. I might as well tunnel right through God Valley!

Kaido: "Don't call me the world's strongest creature on land, sea, and air. Luya is the strongest creature underground!"

Dragon: "Don't call me the master of guerrilla warfare. Luya's tunnel tactics are truly devilish!"

Imu: "Luya, come out! I know you tunneled right through Mary Geoise!"

From God Valley to Marineford, from Ohara to Mary Geoise,

is it really that hard to defeat the Celestial Dragons? The entire underground is my domain!
