From Zhao Hai's point of view, the Church of Light was evil. However, from the point of view of the Church of Light, it was not. In the eyes of the people of the church of Light, what they were doing was right. They were destroying their enemies for the future of the church of Light.
Unfortunately, they were now enemies. Although he admired the Church of Light very much, he had to destroy their operation this time. Otherwise, he would be the first one to suffer.
After knowing all this, Zhao Hai began to make preparations. He secretly obtained some of the two powders from the Church of Light and brought them to Iron Mountain fortress. He gave them to Shunyi's mother for her to help him study them.
Shunyi's mother, su ju, was an expert in using poison. She had learned some of these things in the iron Mountain castle and was now very good at using poison.
