Great Tang: Summon the Unfettered, Recreate the Xuanwu Gate Incident

The Eastern Palace, in the seventeenth year of the Zhenguan era. Li Chengqian was trapped in a desperate situation, with Li Er intent on stripping him of his position as heir and Li Tai closing in from behind! “Ding! Congratulations, Host, you have activated the Eternal Sovereign System. Summoning from the start: 3,000 Unfettered Men and 800 Unfettered Commanders!” Looking at the 800 peerless experts under his command, as elusive as ghosts, Li Chengqian went completely mad. Was 800 men really that many? Back then, his imperial father’s Xuanwu Gate coup had involved only 800 personal guards! Back then, Prince Yan Zhu Di had raised his army in the Jingnan Campaign with only 800 household troops! Since you, Li Er, think you have too many legitimate sons to choose from, then I’ll choose for you! “Yuan Tiangang, pass on my order: kill Prince Wei, Li Tai, and behead Prince Jin, Li Zhi!” That night, Chang’an trembled with fear, and blood flowed through the Eastern Palace! When Li Chengqian, carrying two bloody heads, fought his way into the Taiji Hall, Li Shimin was so enraged he spat blood! “Rebellious son! You dare to repeat the Xuanwu Gate coup? I’ll kill you!” Li Chengqian laid his horizontal saber against Li Shimin’s neck, his gaze icy. “Imperial Father, you’re old! Since you want to be an emperor for the ages, then I ask you to retire and become the Retired Emperor!” Li Er, back then you killed your brother and imprisoned your father here. Today, what’s wrong with me following your example? I’ll take this Great Tang realm for myself!
