Looking Back in Time, My Understanding Doubled

Yang Mao traveled through time and became the son of a guilty minister. His family was in decline and he couldn't eat enough every day. Just when he was desperately waiting to die, he discovered that he could go back in time by stacking silver coins. Every time he goes back in time, his understanding increases exponentially. [By watching the falling snow in winter, you understood the meaning of snow in the sky and created the White Frost Sifang Tianyan Sword Technique. [By touching the ancient trees in the sky, you understood the ancient meaning of the vastness and created the eternal vastness and chaos of mind. But after looking back in time again and again, Yang Mao knew that this world was extremely complicated. Once in the northern territory, the Demon Realm demon clan received the power of the misfortune star in the sky, and the thirteen Demon Realm kings among them joined hands to push across the world thirty thousand miles, turning the entire world into a bloody mess. Once in the fertile land of the south, a hundred thousand demon cultivators killed people and captured their souls, and the innocent souls spread thousands of miles away! Once in the Western Gym, an old Taoist broke the secret of heaven, gods came to the world, and demons danced wildly. After going back in time like this, Yang Mao hid in the small courtyard, quietly accumulating power and forming a force. Until the world was in chaos again, Yang Mao still sat firmly in the small courtyard. And with one command, the world is at peace!
