With the System in Hand, I Protect the Realm

Lu Chengjun, a modern-day veteran reconnaissance soldier, transmigrates by accident to the French Concession amid the chaos of war. Reborn in the body of a watch shop apprentice, he awakens the Weapon Supply System: complete missions to exchange for real historical weapons, from Hanyang rifles to German anti-tank guns, all delivered just in time to help the defenders.

Facing the Japanese invaders, Lu Chengjun uses his watchmaker identity as a cover and forms the Dark Blade Squad:

Raid a Hongkou checkpoint at night, using a Czech light machine gun exchanged through the System to tear open Japanese lines;

Rush to the aid of the Zhabei defenders, building a ghostly web of firepower around the Sihang Warehouse;

Infiltrate Japanese headquarters, using disguises and Thompson submachine guns to sabotage a poison gas bomb plot.

But one crisis follows another:

The Kempeitai’s Hound Squad is already tracking the mysterious source of the weapons;

The approach of Su Wanqiu, a young student, forces him to weigh trust against secrecy;

When the Dachang defenses collapse, the System issues a Gold-tier mission: use heavy weapons supplied for just 72 hours to blast a path to safety for a hundred thousand soldiers and civilians!

“What this era lacks isn’t heroes. It’s a bullet in the chamber when the trigger is pulled.”

Lu Chengjun brings modern tactics into collision with the tide of history. With the System as his blade, he writes the most tragic sniper legend on the banks of the Suzhou Creek.

Even if Shanghai is destined to fall, the Japanese must remember: not one inch of Chinese soil will be surrendered without a fight!
