Ves helped Dulo out in order to accelerate the completion of the Thorn Project.
He not only fed and strengthened the Thorn Project's spiritual design, but also solved a few minor issues that Dulo had overlooked.
Once the Thorn Project reached completion, Dulo chose to fabricate the mech by himself.
"You and your wife have already fabricated your new works by yourselves." Dulo Voiken explained. "There is no reason for me to skip this challenge. I may not possess an impressive collection of masterwork certificates like you, but I have sufficient practice in making my own mechs. The Thorn Project is not that complicated compared to our other mech designs. It is well within my competence to fabricate a good copy."
