I'm looking for a manga based in china about a striving Battle Tactician, in this manga when someone becomes a tactician they make a contract with someone who acts as there general n fights for them. The Tacticians also have a unique special power, Our MC's is incomplete but even so when he uses it he is able to copy/steal another tacticians power. Further in the manga Our MCs friend/General dies or nearly dies leading the crown prince to heal him but in the process of healing him accidentally makes the general forget all about our MC. Oh & when one becomes a Tactician in this manga they apparently stop aging. PLEASE HELP me find this manga! I really want to reread it but I can't for the life of me remember the name or the characters names （/TДT)/
