Taken || Lego Monkei Kid

The day the war ended was the day Sun Wukong welcomed his new son into the world, and the day he put his Staff down for good.

Nearly 18 years later, the world seems to turn upside down when his son and a random human boy lift his Staff and put into motion utter CHAOS.
His son is speaking nonsense, his little brother Nezha wants nothing to do with him, some random human child can wield his staff, and now they are on the brink of war with the Lady Bone demon. Could things get any worse?

Or: Macaque and Wukong unknowingly have twins. One is taken from them to be raised with humans, while the other stays with them. 18 years later, their son runs away into the mortal realm and meets an odd human boy named MK.
MK and Qi Xiaotian are two separate people and twins.
