The white assassin （malereader x hunterhunter）

In the zoldyck family, there was a relatively young boy who was well recognized and well known in the assassin world but no ones ever saw his face, his name was y/n zoldyck and was the 3rd son of the zoldyck, being 1yr older than killua; the government would often hire him to take over some cases that they can't manage to work out and despite your age, you've managed to solve every single case you've ever taken on with little to no difficulty.

even though he was an extremely skilled assassin, his main role in the family was collecting information, so what would happen if he was requested by his mother to follow his younger brother to the hunter exam?
