Is Chu Xiu cold-blooded?
Of course.
But, he doesn't intentionally act indifferent to emphasize his cold-blooded nature.
In Chu Xiu's view, true cold-bloodedness is extreme self-interest.
Are serial killers considered cold-blooded? Certainly, but so are those who seem amiable in daily life, even do charity to build a reputation, yet accumulate wealth by exploiting people behind the scenes.
Chu Xiu prefers to be the latter.
Because the latter can blend into society and grow stronger by leveraging others' strengths.
So in Chu Xiu's eyes, the goodwill of people who can help him is also an important "benefit."
Shen Zhuo is one of them, Yun Lu is another.
The former's family can provide him with support, while the latter's talent for finding food allows him to focus more energy on exploring upgrades.
Although even without these assists, it wouldn't have a significant impact, Chu Xiu won't miss even the smallest profit.
