It’s not that he can only use them once, more like it strains his tiny fragile plate! Those powers are called ancient powers and usually it takes someone with a large plate like Choi Han’s and the luck to encounter them and to pass their tests to earn them! Cale’s plate is tiny and usually shouldn’t be able to hold more than one (anyone with more than one usually explodes and dies) but luckily if you read the novel it explains that the order he gained them helped balance his plate! P.S. the water one you saw of him using in a forest (guessing) on tiktok isn’t an ancient power!!! Rather it’s more like a substitute. I don’t think the Manhwa reached the point of him gaining the water ancient power yet. I recommend reading the novel, it’s sooo funny how he interacts with them!
I’d recommend to start from the very beginning!
You can find and read them online in eat apple pies as recommended by novelupdates, or download the epubs if you search in google there are tons!
The novel is also officially released so you can buy the books on amazon and stuff!
On youtube there are also audio versions of the chapters! Or you can just use the safari extension ‘listen to page’! To read whatever chapter you’re up to in 10-15min!
I’ll leave the my epub link here it’s free

The only weakness of this story is that none of the characters in this story are ugly, whatever their role in this story, they all look very beautiful and charming waaahh I love them .˚‧º·(ฅдฅ。)‧º·˚.
