Zhang Jianguo was an elder of the Purple Mountain sect in the middle stage of the nascent Soul realm.

This novel mentions the name 'way of the devil''s mc.
Zhang Jianguo's system is based on  'deep blue.'

Still, if you like Way of the Devil, try this one.
The main character is rational, ruthless, and pragmatic.
