The System Came Early and Started to Counterattack at the Age of Two

Outrageous! Shen Yun traveled back in time to a time of troubled demons and monsters. He was only two years old, and the counterattack system came fifty years earlier. Becoming the most favored eldest grandson of Marquis Shenwu, Shen Yun thought he was hallucinating, but then he realized that the system was "mentally retarded". [Congratulations, at the age of fifty-two, you pulled your grandfather Shen Lie's beard and made him smile. Reward "Cangyu Divine Blood". [Congratulations, you defeated an enemy at the peak of the Nirvana Realm after being seriously injured and dying, and obtained the "Unparalleled Sword Body". [Congratulations, you refused the marriage offer from the Emperor of Zhou Dynasty and obtained the human artifact "Kongtong Seal". The "mentally retarded system" that was supposed to appear when Shen Yun was dying came fifty years earlier, and Shen Yun was able to accomplish the task that was originally impossible. Since then, all kinds of natural and earthly treasures have come to hand, and Chen Yun has stood at the pinnacle of his life quietly. Shen Hao, Tianjiao's cousin who betrayed the Shen family and joined Northern Xinjiang, led thousands of troops and set foot on Dazhou's borders, killing Dazhou's blood like rivers. Armies from various countries invaded on a large scale. Shen Yun said "Sword is coming", shattering all Shen Hao's pride and killing tens of millions of troops on the battlefield. Shenwu Hou Shen Lie: My grandson has the appearance of an immortal! Emperor of the Great Zhou Dynasty: Confess Chen Yun as General of Heavenly Strategy! No! What if the emperor's position is given to Aiqing?
