As far as I can remember, he knows that qin can read minds. At some point he even used this knowledge as a leverage to manipulate qin so that he could move into the next mission
He did not acknowledge that he realized this version of Qin has gained his mind-reading abilities yet. So I don't know if he is even thinking about it right now because he is, once again, focused on the mission.
MC doesn't know about Qin's mind reading abilities in this version yet.
If I remember correctly, MC tested if this Qin version could read his mind and he couldn’t. Later on Qin did get his mind reading capabilities
Exactly. He only tested Qin's mind reading ability in the beginning (when he didn't have it yet) but after Qin proved to have it Wang Yi didn't seem to realise it.
Ch149 Does this MC already know about Qin's mind reading ability? I remembered in previous chapters...the MC thought something about cruel, then Qin responded out loud "Cruel?". But the MC did not looked surprised that Qin responded to the MC's thought.
