The System of Rebirth Forces Me to Open an Inn

I'm so unlucky. Others who traveled through time and were reborn were either geniuses in cultivating immortals and formed elixirs within a year. After two years of transforming into a god, he either comes with a cheat that defies the heavens, pretends to be a pig and eats the tiger, or the god blocks the god and kills the god. The worst thing is that it can also be bound to an "all-round exchange system", with the skills and artifacts of your choice, and you can reach the pinnacle of your life. And what about me? His reborn identity was that of an innkeeper in a remote rural area. He had no shop, no waiters, and only a polished commander. The bound system is called "Thrifty Housekeeping". In the redemption interface, all of them are "Qingxin Tea Egg Refining Method", "Overnight Steamed Bun Rejuvenation Technique", "Broken Flowers and Rotten Fruit Brewing Technique"... I just want to ask, what can I do if I learn this thing? ! Open a beggars theme restaurant? !
