2-C??? Bro this is for Non-Smurf stuff. Is the 2-C inevitable, or is it just a possibility (ie you can remove it in a match)?
Additionally, from what I'm seeing, his regeneration is only for Info type 2, not Concepts. So like, he'll just get erased.
How does his deconstruction work, and even then, how would he do it before Wang Wei just insta-fate cockblock him? Additionally, his concept resist stretches to A LOT of things, including absorption shenanigans (Hell, the reason he has resistance is because characters have concept stuff from 7th realm and onwards, and those typically include Absorption. Wang Wei's absorption even comes from a dude who has absorption that was stated to absorb everything, including concepts).
Even then, ignoring all of the above, you'd need to bypass his passive fate manip that doesn't allow him to die.
As for his intuition, he had it from his time on earth, and it gave him a sense of danger to anything that might happen, that is so far above other cultivators sense of danger (which could sense conceptual shenanigans), and the moment he met someone who could fodderize him, Wang Wei immediately went with shackles of fate (which at this stage is thought-based), that made his opponent toy with him instead of killing him.
Also, he has Bone Clone, which summons a clone that'll allow him to survive any attack (Conceptual, Causality, Reality Warp, etc...)
Regardless of all what I said above, Wang Wei has reaction/thought speed of 33 Billion times the speed of light, which 3.3 million times his normal speed, so he'd just see Mujin as a statue, and can just do whatever he wants with Fate Stuff.
