A case affected tens of thousands of people. What happened to the "evocation case" in the Qing Dynasty?

This case happened during the Qianlong period, when a stone bridge needed to be built in Deqing County, Zhejiang Province, so the government gave the task to a very famous local stonemason to build a durable stone bridge. When the stonemason was about to start work, a good friend came to see him, but they didn't have close contact on weekdays. The stonemason asked him the purpose of his visit, so his friend told him the purpose.

At that time, it was rumored that the stonemason's hand could play a curse role, and it happened that his friend's nephew was very unkind to him. Because his friend had no children, he wanted to adopt all his property to his nephew, so that they could support themselves in the future, but his nephew did not come as agreed before, so he thought of this way to curse his nephew.

The stonemason didn't believe this rumor at all and decisively rejected him, but his friend was still here to beat him, so he was sent to the government without any choice. The government beat his friend to the top 20 and sent him back, but it didn't end.

Later, another beggar lied that he could take away the child's soul with a spell. Although this incident was later suppressed by the government, the people at that time did not think so. After the news spread, there was a subsequent soul call case, and the storm intensified. It can be said that the situation is completely out of control.

Then Qianlong was furious and ordered a thorough investigation. I didn't know that there were 12 provinces in this case, adding up to more than 10000 people, and 10000 people died.
