You Were Sent Undercover, but Became a Navy Admiral

Chen Feng transmigrates to the world of "One Piece" and becomes one of Blackbeard's crew, tasked with going undercover at Marine Headquarters to gather intelligence.

He had given up on life, but unexpectedly awakens the Alliance Summoning System.

Sakazuki: "Chen Feng, go get my cigar."

Then a hulking man with a greatsword strapped to his back suddenly drops from the sky.

"Come on! Let me show you darkness!"

Seeing the hulking man's figure, Sakazuki hurriedly says,

"Please, go on with your tea. Enjoy your tea."

Blackbeard: "Chen Feng, where's last month's intel?"

Then a burly man carrying an axe appears, casually tossing it from hand to hand.

"Oh! This unstoppable power!"

Blackbeard: "???"

Chen Feng: "???"
