To express "even more," (as in "even more expensive," "even more ridiculous," "even more badass"), use 更 (gèng). It frequently comes before adjectives.
Structure:
The pattern in Chinese is simple:
更 + adj.
Examples:
Note that this pattern is not simply a way of adding "-er" to an adjective. It's not a substitute for 比 comparisons. In each case, you're adding even more to an existing considerable amount, as in, "I'm already rich, but I want to be even richer."

不要 太 高兴，我们 还 有 更 多 的 工作。
Don't get too excited; we still have more work to do.
Structure with "比":
While 更 is not a substitute for 比 (the classic comparison word), the two can be used together.
A 比 B +更 + adj.
This expresses that "A is even more Adj. than B."
Examples:
Jīntiān bǐ zuótiān ɡènɡ rè.
今天 比 昨天 更 热。
今天 比 昨天 更 热。
Today is even hotter than yesterday.

这 个 女孩子 比 那 个 更 漂亮。
