The Engineer Who Built Heaven

Civil engineer Liu Yang died in a bridge collapse. When he transmigrated to the Heavenly Domain, he found the celestial realm in shambles — crumbling cloud bridges, leaking qi pipelines, a Jade Emperor who's been trying to fix the same leak for 800 years. The immortals have infinite power but zero understanding of structural integrity. Armed with a calculator, reinforced qi-steel, and a very unimpressed attitude toward divine architecture, Liu Yang is going to renovate heaven. Whether the gods like it or not.
