小说诚不欺我,作者果真是穿越的高危人群
小说 = novel
诚 = honest, sincere, true
不 = not
欺 = take advantage, deceive, cheat
I think hong chi is saying that she won't let the novel take advantage of her
作者 = author, writer
果真 = really, as expected
穿越 = pass through, overcome (穿越者 is a timetraveller)
高 = high, above average
危 = danger
人群 = crowd
the author that has transmigrated is dangerous
basically hong chi thinks that shangxue has useful/powerful information that wasn't included in the story which can help them complete her goals/escape the plot.
