Three Kingdoms: Summoning the Sui and Tang Heroes, I Fused with Li Shimin from the Start

Li Ya transmigrates to the chaotic final years of the Han dynasty, rejected by the world and targeted by everyone. Fortunately, he awakens a check-in comparison System. By checking in at famous people and iconic moments, he can summon their Sui and Tang dynasty counterparts. From the start, he checks in at the Oath of the Peach Garden, fuses with Li Shimin's template, and embarks on the path to supremacy in a chaotic age. He checks in at Guan Yu and summons Qin Qiong. Guan Yu versus Qin Qiong: the age-old debate plays out for real! He checks in at Lü Bu and summons Xue Rengui. Which Fangtian halberd will prove superior? He checks in at Zhao Yun and summons Luo Cheng. White horse and silver spear versus icy gaze and cold spear: who will reign supreme? He checks in at the Trapped Camp and summons the Mo Dao Battalion. When two forces meet head-on, which side is truly braver? He checks in at the Tiger and Leopard Cavalry and summons the Black-Armored Cavalry. Which will claim the title of greatest heavy cavalry? Diao Chan versus Yang Yuhuan; Zhen Mi versus Wu Zetian; Da Qiao and Xiao Qiao versus Dugu Jialuo and Empress Zhangsun... A contest of beauties: who will outshine them all?
