Copy the Way of Heaven at the Beginning: I Am Invincible in the Nine Realms

[Rebirth + system + exciting battle] In his previous life, his classmates had his heart and bones stolen. After his rebirth, Chu Xingyun awakened the "Tiandao Reproduction System". Not only can he copy the opponent's skills, but he can also obtain the Chaos Holy Body by signing in in the secret realm! When the former enemy comes to bully you again—— "Ding! "Burning Sky Sword Art" was detected and copied successfully!" "Ding! The sign-in reward for the Burial God Abyss is "Time and Space Hourglass", which can be used to review the battle situation for three seconds! " Chu Xingyun's backhand was a fusion skill "Nine Heavens of Ice and Fire Critical Hit +99999", which directly destroyed the opponent's Nascent Soul! What's even more amazing is that the system can also deduce the opponent's movement trajectory within three days, allowing him to win consecutive battles in the Canglan Academy competition and counterattack from a loser to a genius in the Xuji realm! However, there are dangers everywhere: -Nangong Li, the princess of the Xuanxiao Empire, holds the Tianji Mirror and predicts that "the disaster of destroying the world will start from you." ​ -The frozen heart of Su Qingxue, the saint of Hanyue Palace, needs his blood to unblock it. ​ - Mei Jiuli, a demon from the Nether tribe, sneaked into the room late at night and stole the "Hongmeng Secret Book" When the four empires competed for the "Fragments of Heavenly Dao" and triggered a melee in the nine realms, Chu Xingyun formed the Dao Alliance. He held the Burning Heaven Cauldron in his left hand to suppress the millions of insect waves, and held six beauties in his right hand to go to the Taixu Heavenly Palace together! With each upgrade, the natal star chart that appeared behind him changed, and a warning suddenly popped up on the system interface: "It has been detected that there is an overlap of cause and effect between the host and future self, please terminate the skill copy immediately!"
