Introduction:

Lin Xia's dream is to have a comfortable environment and live a carefree life in the navy until retirement.

I leave work before the scheduled time every day, and I get ten days off a month. Life is so carefree.

...

But the Navy Headquarters actually banished Rocks to the West Blue, along with Edward Newgate, Shiki, Charlotte Linlin...

These notorious pirates have all arrived in the West Sea, and Lin Xia's carefree days are over. He roared, "My vacation is gone!"

...

Lin Xia set off for the Navy Headquarters and rushed straight into the Admiral's office.

Lieutenant General Garp laughed heartily: "So you've finally decided to come out of the West Sea?"

Sengoku Vice Admiral's eyes gleamed: "The purge plan can begin. Shall we start with Shiki, or..."

Lin Xia smiled and pointed to the Void Throne of the Holy Land:

"I'm just here to apply for leave. If it's not approved..."

"Then..."

"Take that thing apart."

"You actually want to demolish Mary Geoise, the home of the Celestial Dragons, descendants of gods!?"

He never imagined that Lin Xia would either not show up at all, or if he did, he would cause such a huge stir!

He actually dares to say he'll tear down the throne—what makes him think he could possibly do it!

Steel Bone clenched his teeth and roared, word by word:

"You just want to take a vacation, right? I approve!"
