I'm Just a Butcher, I Really Don't Want to Be an Emperor

Zhao Tieshan's biggest dream in this life is to buy the empty shop next door and kill two more pigs. He picked up a crying girl under the old locust tree. The girl was carrying a jade pendant. There was a keyhole the size of a needle on the back of the jade pendant - and the round buckle under the handle of his pig-killing knife clicked just right into it. Zhao Tieshan was confused. He has been killing pigs with this knife for more than ten years, but he never knew it could open jade. Even more confused at the back. The adoptive father's last letter said: This pig-butchering knife is (the butcher's knife used by the founding emperor), a royal ancestral token, and was stolen from the royal study by your father and used to kill pigs for twenty years - purely to humiliate the old emperor. Do you think this is the end? Even you stole it. The third prince of the old emperor was carried out of the palace with a knife and others on the day he was born, and worked as a butcher incognito. Zhao Tieshan: (ˉ▽ˉ;)... What I kill is not a pig, but my life. Three locust flower jade pendants conceal the talisman of the 300,000-strong army in Northern Xinjiang. To open the lock, you rely on the butcher's knife, and to decode it, you rely on the nursery rhyme A Huai girl has sung for more than ten years - when you meet Zhao, you open it, and when you meet Huai, you unlock it. The person who carved these eight characters probably didn't expect that twenty years later they would be brought together by a pig butcher and a runaway wife. Along the way, the heroine in white came to the rescue and found out that she was the mother-in-law. A down-and-out veteran who fell to the ground after being hit by an arrow returned with an army of fake corpses two years later. Even Zhou Xiucai, who had scolded A Huai for "not laying eggs", was finally found out that he was the one who couldn't do it. When Zhao Tieshan finally sat on the dragon throne with the butcher's knife and the military talisman, the villain sneered before he died: "Do you think I am the last one?" — Okay, the butcher knife can be used as a key, what else?
