Ves pulled out the radiant lottery ticket from his System Space.
The ticket was quite precious and troublesome to acquire. He could only obtain it by fabricating a new masterwork mech of his own design.
There were other criteria. It had to be a serious project. His contribution had to be decisive enough.
He couldn't just outsource most of the grunt work to the other members of the Design Department, only to swoop in at the last second and finish the project in person.
To claim that it was mainly his work was a form of professional dishonesty that he could not abide by. He was not that shameless enough.
