Sui and Tang: Summoning Mighty Generals

Sun An, a modern man with nothing going for him, has his soul sent back a thousand years and becomes a low-ranking Sui army officer. After awakening a Summoning System, he joins the first major campaign against Goguryeo. With the mighty generals summoned by the System, he earns distinction and returns victorious to the Sui. He fights Dou Jiande in Hebei, kills Zhai Rang at Wagang, captures Wang Shichong in Luoyang, ambushes Du Fuwei in Jiangnan, and defeats Li Shimin in Taiyuan. Campaigning across a thousand miles, he goes on to establish the glorious Great Ming!
