The Madman of the Tang Dynasty Whose Soul Has Penetrated the Tang Dynasty Starts with a Shop

[Funny + Relaxing + Systematic] The protagonist Li Ping'an was originally a junior student in 985. When he was sleeping in the school dormitory, his vision suddenly went dark and he fainted. When he woke up again, he appeared in a small antique shop. At first, he thought it was a prank by his roommates. He even found the "actors" outside, and it must be said that it was really realistic. However, after he asked around "those actors", they all looked at him as if they were a fool. Suddenly, a memory belonging to this body flooded into his mind. It turned out that this place was during the Tang Dynasty, and it was just after the Xuanwu Gate Revolution. When Li Shimin was the emperor, it was also the heyday of the Tang Dynasty. This place was Chang'an City. The original owner of this body was also named Li Ping'an. He was just a famous fool and madman, and a very handsome fool. After his parents passed away, he completely destroyed the huge property left to him, leaving only a small shop. After a long time, Li Ping'an finally accepted the reality of time travel, "I just sucked up a tube and came here for me? Fortunately, even if the original owner was ruined, fortunately it was during the prosperous period of the Tang Dynasty, but how to make money now? Brewing? Soap? Or...?" Because the original owner was addicted to gambling and still had debts, someone would come to collect them soon. If he couldn't pay them back, it would really be over. Just when Li Ping'an was at a loss what to do, an electronic voice suddenly came to his mind, "The Datang Supermarket system has been turned on!" "System?!" Li Pingan was overjoyed! "It has been bound to a shop under the name of the host, and a gift package for beginners will be given: the realm of martial arts grandmaster."
