All-player Dungeon: Start with a Thousand Souls Banner

Liang Ming, a young man from the solar system, unexpectedly transmigrated to a world where everyone is required to participate in dungeon crawling upon reaching adulthood. In the beginner dungeon, he stumbled upon a tattered banner of ten thousand souls, embarking on an unimaginable path. He collected remnant souls, refined spells, hunted demon souls, and commanded ghostly soldiers… Those who opposed him called him a heretic, but only he knew it was efficiency! …Thousands of dungeons, thousands of tribulations, thousands of worlds, thousands of opportunities. He witnessed the wandering swordsmen in the night rain, the end of centuries of grudges. He also saw demons rising like a tide, and heroes standing firm against the tide. His obsessions were too long, and his life too short; he hadn't seen enough, so he invited them all to the banner of ten thousand souls for a reunion. He didn't know why no one ever refused; perhaps it was because he was popular?
