I'm Waiting for the Flowers to Bloom in the Wilderness

When Su Changqing woke up, the mountains and rivers were shattered, and all the old people were dead. He was once the Taoist Master of Taichu, and he could open up the world with just one thought. Now he can only sit in front of his tomb and watch the moss on the ruined monument wither and grow a hundred thousand times. In this world, spiritual energy is filthy, laws have collapsed, and no one can recognize his name. Someone asked him why he sat here for so long. Su Changqing pointed to the barren grave at his feet: "I'm waiting for a flower. When it blooms, I'll take another look... Where did I go wrong in these one hundred thousand years?"
