Bright Sword: The Brilliant Strategist Li Yunlong

[A Bright Sword fanfic + strategic mastermind + no System (being able to transmigrate and know what's coming is the ultimate golden finger)!] I, Li Yunlong, a top graduate of the National Defense University, am completely freaking out. Because I've transmigrated into myself, and I'm surrounded by the Sakamoto Regiment at Cangyun Ridge. Once Li Yunlong stops charging in blindly and starts using tactics and technology... Wang Chengzhu becomes the "God of Artillery," hitting whatever he aims at; Wei the Monk becomes the "King of Soldiers." Hand grenades made in the border region double in range and power, blasting the Japanese until they question reality. Brigade Commander: "Li Yunlong, I congratulate you on getting rich!" Me: "Reporting, Brigade Commander! Here's the detailed report on this operation, the equipment inventory, and our development plans. Please review them!" Brigade Commander: "...Who are you? Give me back my Li Yunlong, the one who yells like a madman!" Chu Yunfei: "Brother Yunlong, now that I've seen you in action, I realize the Eighth Route Army really does have a man of your caliber!" Me: "You're too kind, Brother Yunfei. Coordinating infantry and artillery, using the three-three formation... It's nothing worth mentioning." Okamura Yasuji listed the New First Regiment as North China's greatest threat. His report contained just three words: Impossible to defeat!
