Infinite System: I Sell Instant Noodles in Another World

I have been at home for a year and ninety-eight days, and the fear that haunts me every day almost makes me collapse. But, I got through it and I got stronger. I obtained the system and was transported to various alien continents for adventures. The fat house coins I obtained allowed me to solve the problems that had been bothering me, and thus discovered the deep sub-core of today's world. This is an era where hundreds of schools of thought are contending with the system. Every successful person has an assistant in the system, but I have an advantage that no system owner has. I can freely travel between this world and another world, and thus start a cross-border business. This novel and its characters are purely fictitious.
