The System Arrived 15 Years Early, and I Make Xiang Yu Cry Every Day

【Qin Dynasty Era + System Malfunction + Relaxed Everyday Life + Beating Up Bratty Kids + Invincible Protagonist】 Xiao Chen transmigrates into the Qin Dynasty era and becomes the son-in-law of Xiang Liang, young master of the Xiang clan. Just three days after the wedding, the Reversal Fate System malfunctions and arrives fifteen years too early! Looking at the group of children playing in the courtyard, the System issues a piercing red alert: 【Host in danger! You face certain death in the future!】 【Fifteen years from now, your father-in-law Xiang Liang will raise an army against Qin and shake all of China!】 【Your brother-in-law Xiang Shaoyu will become the Hegemon-King of Western Chu, mighty enough to lift mountains and awe the world. Because he resents you for living off your wife, he'll pin you to the city wall with a single halberd strike!】 Xiao Chen looks at the terrifying rating on the panel: “His courage is divine, unmatched throughout history.” Then he looks at the five-year-old Xiang Shaoyu in front of him, with snot running down his nose and barely able to hold a little wooden sword steady. Xiao Chen can't keep the grin off his face. “So, you're the future Hegemon-King of Western Chu?” “You're going to pin me to a wall?” 【Ding! Hell-level mission issued: Survive the Hegemon-King of Western Chu's ‘Hegemon's Formation-Breaking Dance’!】 【Reward: Max-Level Dragon-Elephant Prajna Skill + Guiguzi's Vertical and Horizontal Sword Intent!】 Seeing the System's warning that “contact means instant death,” Xiao Chen slowly rolls up his sleeves, walks toward five-year-old Xiang Shaoyu, and gives him a kindly smile: “Shaoyu, your brother-in-law is going to teach you something: A Chu man sheds blood, not tears.” “The System says you're strong. I don't believe it.” “Take this! The Mountain-Sized Father's Love Slap!” Years later, Xiang Yu, the Hegemon-King of Western Chu, destroys his own cauldrons and shakes the world. Yet whenever he hears the name “Xiao Chen,” he instinctively covers his backside and trembles: “Father! I really wasn't slacking off! I'll go lift the cauldrons right now! Just make brother-in-law put his sword away!!”
