After completing the core components, Shi Feng directly handed all of them to Melancholy Smile.
The production of small ballista carts was extremely complex and required numerous parts, but aside from the core components, advanced professions could easily handle everything else.
As for the final assembly, Scorching Abyss's skills as an Engineering Master were more than sufficient for the job.
