World Conquest Starting from Conquering the Great Tomb

Crimson Eyes, Pirates, Naruto, Fate... Chen Danyang, who has a system to conquer the world, advocates truth, goodness and beauty that many people look down upon. Therefore, since he has the power to save tragedy, of course he must do it to save tragedy. Only when darkness is deep can there be depth? But fuck it. Of course, although he advocates truth, goodness and beauty, Chen Danyang is just a common man at heart, so whether it is the power of Devil Fruit, piloting a giant mecha, experiencing magical eye skills, winning the Holy Grail War... Etc., He has to do it all. That's right, this has never been a savior's story. Whether it is advocating truth, goodness and beauty, or longing for power, it is Chen Danyang's own desire. This is a story about a powerful layman who talks to himself and conquers thousands of worlds. "Hypocritical? Pretentious? Shameless? Great? Sublime? Handsome? Alas, it doesn't matter whether you praise or criticize. For my own sake, I ignore the comments of others. This is me, the conqueror of all worlds!!" - Byd Chen Danyang. And this story starts with Overlord.
