now that I think of it... Eden isn't he mixed product of MC's last broken self(1st test's last personality of mc who is silly, obident) and the rest of broken self were eaten by mc but not the accumulated energy/emotions/memory as he was not just eating his own soul but different personalities which born in that test and all except last one who was eaten by big tree but main mc eat tree and all accumulated memory/ energy/ emotions were thrown into making this Eden heart. because of tree has big data it took the lead of all memory slowly dominating it(I think so) and other it has mind dao as being made of consciousness not soul. now with those lots of events it can obviously has better grasp and multitasking abilities in mind domain. maybe this is another reason why Eden is better at alchemy, cultivation and handling mind related task in MC's body.
