As a son or daughter of China, if you gained power that made you invincible, wouldn't the first thing you do be chase down the Sakura Nation and beat them up?
After a deep blue glow enveloped the entire world, humanity underwent a profound transformation: the Age of Awakening began. Nuclear energy vanished, and gunpowder-based bombs no longer worked as they should. The world descended into chaos, but China remained as peaceful as ever.
Some people couldn't stand seeing China at peace and kept trying to stir up trouble. Just as China teetered on the brink of chaos, a Daoist who had practiced since childhood chose to enter the mortal world to protect China and take up the path of slaughter to save its people.
After an accident led doctors to mistake Peng Hao's Golden Core for a kidney stone and remove it, he awakened a supernatural ability. From then on, he soared to greatness, wielding three thousand Daoist arts with ease and mastering his sect's swordplay. If that still wasn't enough to defeat his enemies, then this poor Daoist also knew a little hand-to-hand combat.
After joining China's Sixteen Guards and restoring stability to the country, he immediately set out to trample all four islands of the Sakura Nation. Then he chased them around the world, beating them up wherever he found them. If asked why, he'd say: "As long as the Sakura Nation still exists, I can't rest easy."
After that, he couldn't stand the sight of anyone. The words he said most often were: "Your existence is a threat to China, so please die."
