People with character flaws are easier to befriend.
For someone as proud and arrogant as Cao You, as long as you can appreciate his shining points, you can become his good friend.
Once the guard of the heart is opened, it's much easier to discuss matters.
The difference between talking with one's own people and with outsiders is as vast as the heavens and earth, both in terms of content and scope.
For Tang Luo, befriending Cao You wasn't part of the plan, but the appreciation was sincere.
And this sincerity brought a good return, as Cao You candidly told Tang Luo why the Beast Taming Sect had little interest in the much-talked-about cosmic exploration.
"The third saintly path is fine, but have you ever thought about what would happen to the world once the Divine Monarchs and Saint Kings, who maintain the firmament, are gone?"
