Siheyuan: Eagle Eye from the Start, Tearing Through the Enemy Spies in the Courtyard

In his previous life, he was the special forces king known as "Dragon Thorn," killed by a traitor within his ranks! The moment he opened his eyes, Long Jianjun had transmigrated to the Hongxing Courtyard of the 1960s. He thought it would be nothing more than petty squabbles in the bustling courtyard, but then his System activated. The place was actually a nest of spies that had been lying low for years! [Eagle Eye Insight] activated: everyone was marked as a hostile! The righteous-looking First Master? [Yi Zhonghai: Deep Red, enemy agent codename "Fitter"!] The pitiful Qin Huairu? [Qin Huairu: Deep Red, enemy agent codename "Spinner"!] The venerable Deaf Old Lady? [Deaf Old Lady: Deep Red, enemy agent leader "Old Buddha"!] And Xu Damao and Jia Zhangshi? All lackeys in this vast spy network! Stealing soy sauce? That was passing information! A machine tool malfunction? That was sabotage of military production! Looking at the courtyard full of "monsters and demons," Long Jianjun gave a cold laugh and whipped out a pair of gleaming silver handcuffs. "You want to play house politics? I'll launch a full-scale crackdown instead!" Mission issued: investigate the accident at the steel mill! Long Jianjun set a trap to draw the snake from its hole, interrogated Xu Damao through the night, drove Liu Hai mad, and dismantled the sabotage cell before dawn! Rewards: Master-level combat skills, microexpression analysis, and 500 jin of premium cigarettes and liquor! Starting as a gate guard in the security department, he rose through the ranks at breakneck speed! Yi Zhonghai panicked, Qin Huairu was terrified, and the Deaf Old Lady raised her cane... "Little Long, you know far too much..." Long Jianjun lit a cigarette and reached for his waist. "You old fossil, you can't hide that fox's tail anymore!!!"
