Espionage: Transmigrated to the War of Resistance, I Become the Sakura Syndicate's Mastermind

Note: The early story features aristocratic spy games. After the protagonist takes control of Sakurabana, the story moves into a worldline resembling The Man in the High Castle!

Sign-in + logically consistent aristocratic status + rats within the enemy ranks + not returning home after the war + an unconventional take on the War of Resistance

This story won't leave you feeling frustrated. The protagonist has powerful connections in the navy, army, and Foreign Ministry, so feel free to dive in.

After transmigrating to Shanghai in 1939, Zhou Ning becomes a second lieutenant squad leader in the military police.

As he stirs up trouble within the enemy ranks, he activates the sign-in System.

All he has to do is sign in every day to receive items, which can be delivered to a specific location. Note: The System isn't absurdly powerful. In this life, Zhou Ning will use his predecessor's identity to take the path to controlling Sakurabana.

See how the protagonist uses his personal connections and increasingly powerful sign-in abilities to forge a unique path to kingship in this new world.

This is a parallel world and a multiverse. Don't read too much into it!
