Martial Peak - Ch. 994 - I’ll Give You A Chance To Prove Yourself

[Kaarme]

If you think about it, she's not wondering at all why Yang Kai has such treasures. Why he paid the 100 high grade saint crystals like it was nothing. That suggests she's actually used to an environment where that's normal. Just like she said she hasn't seen precious materials for so long, which means in the past she had access to them. Although no matter what, even if she was "just" a saint king rank refiner, she would have still needed to train helluva lot in the past to reach that point. Yang Kai has also trained alchemy quite a bit, even if he's also godly talented.
