Soul Eater Oc

The super cultivation genius, renowned across the continent, succeeded in solving a puzzle and obtained a mysterious crystal. However, he was killed and betrayed by his fiancée, who feared that Samuel’s clan would grow stronger with the crystal and dominate the other clans. His soul was saved by the mysterious crystal, locked inside the crystal space for a thousand years, where he was forced to learn various skills and abilities. He was later reincarnated into another world, a modern world where he must grow powerful in the shortest time possible or die. In order to grow powerful faster, he needed a huge amount of wealth for resources. To gain such wealth, he had to apply the knowledge he had learned from the crystal space.
