It's obviously a life skill, but you developed it into a magical skill

In the ten years since the Great Chu, strange things have happened everywhere.
When he woke up, Zhou An became a yamen agent.
Crisis is always there, but fortunately Zhou An brought a small game made in his previous life.
As long as the life-exploding skills are used, the skills can undergo qualitative changes and become magical skills.
Knife skills - open the sky with one knife.
Turn the pot over - the Kingdom of God in the pot.
Swimming - making waves.
Several years later, Zhou An said that all he knew were common abilities in life.
The crowd was furious.
"You are talking nonsense, I saw you split the sky with a knife!"
"You're lying. I saw with my own eyes that you put a ten-foot-tall weirdo into a pot and beat it to death!"
"You said you can swim, but the huge waves have nothing to do with swimming!"
Facing the angry crowd, Zhou An sighed and took out a small sword as wide as his palm.
"I have learned a lot about blacksmithing recently, and I will show you how to defeat all magic with one sword."
