Reborn as an Undercover Agent: I Laughed Out Loud from the Start

Jiang Xiao, the police academy's first "least serious student."

After an explosion, he was reborn three years in the past and bound to the Undercover Training System.

From then on:

Others rely on restraint when going undercover; he relies on running his mouth.

Others use threats during interrogations; he tells jokes.

Others are afraid of having their identities exposed; he is afraid he won't be able to hold back his laughter.

Gang leaders are scared of him, the police brass dote on him,

and even the System gets roasted into upgrading and begging for mercy:

"Host, please stop talking... The enemies are laughing themselves to death!"
