Building Mechs with My Sweet Little Wife in Another World

Just who is Xiao Yunfan?

In Xianju, the Lin family not only gives him money and a mansion, they even want to give him their daughter as a wife!

And he can't refuse?

What?

He has no soul power? Then why is that busted old hammer moving on its own?

He can't summon spirit beasts!

Who needs spirit beasts when building mechs is so much better?
