It gets really really slow, and focuses on merchant making. Not to mention Hibiki tries to NTR Lime away from Tomoe, well, its not really NTR, but Lime is Tomoe's servant, and she tries to steal him.
Also he gets so Overpowered, His power is reality bending in his bubble. That is why he can create a new world, something the shitty goddess can not even do.
So basically the author could end it there, but he doesn't. Not to mention Tomoe and Mio could wreck the entire content by themselves without even breaking a sweat.
IT has its moments, but it took a steep downhill interest probably a few more arcs after this.
