My Supermarket Is in Ancient Times

When Li Sheng'an woke up, he found that he and his small supermarket had traveled to the Tang Dynasty in the parallel world, and he could also return to the modern world through the back door of the supermarket. I thought that with such a powerful golden finger, I would be able to live a happy life of controlling the world's wealth and being drunk in the lap of beauties in the Tang Dynasty, which was called the Kingdom of Heaven. But he soon discovered that the Tang Dynasty in this parallel world was completely different from the Tang Dynasty in history. There are internal and external troubles, and powerful enemies are surrounding us. There is nothing like a heavenly kingdom. Looking at such a weak Tang Dynasty, Li Sheng'an shook his head helplessly, alas, forget it, since the Tang Dynasty in this world is not a celestial kingdom, then let me personally start an era in which all nations come to dynasty.
