Why did Jiang Ziya freeze Qishan to kill tens of thousands of creatures in the battle of sealing gods?

In the novel, Jiang Ziya has always been the image of caring for the world, but Jiang Ziya was uncharacteristic in the battle of deification. Qishan was frozen and gave Zhou Wenwang a magnificent tree.

I believe many people have read the novel The Romance of Gods. This article mainly tells the story of Jiang Ziya's disciples who, under the leadership of his master and apprentice, helped attack Zhou and launched a war to seal the gods. In the novel, Jiang Ziya has always been a respected and compassionate figure. However, when Lu Xiong, a general of Shang Dynasty, led 50,000 troops to the foot of Xiqiao Mountain, Jiang Ziya uncharacteristically cast spells to freeze Qishan. Not only fifty thousand commercial soldiers were injured, but three thousand people were killed on the spot. Many creatures who had no time to leave Qishan were also hurt.

Actually, worshipping God doesn't have to kill people. Jiang Ziya was uncharacteristically in this war, mainly to establish his own authority. In previous wars, there was always a master in the commercial army, who either didn't fight or was beaten up by the other side. Nezha, Yang Jian and other nephews didn't say anything, but they still looked down on Jiang Ziya. And Jiang Ziya is also worried about the long-term impact on his position in the West Shu army, so he can't wait to make contributions by killing people.

There are thousands of ways to kill people, but Jiang Ziya has to choose the way of freezing Qishan. This is mainly related to Jichang and Zhou Wenwang. As we all know, Ji Chang was famous for his divination before his anti-Shang. When Fei Zhong and Ghosts used to go to Xiqiao, they used to look for Ji Chang to calculate their lives. When Ji Chang worked it out, they all froze to death, but Fei Zhong and Ghosts were able to shrug off it. For this matter, Jiang Ziya also knows. Now he used magic to freeze them to death, didn't he fulfill Ji Chang's prophecy? But also can set up a mysterious image for Zhou Wenwang. So Jiang Ziya killed Fei Zhong and the wandering souls for himself and frozen Qishan for Zhou Wenwang.
