He also thought about committing suicide to follow Prince Yi Yong, but he was not at ease leaving the Emperor. He wanted to live to monitor the Emperor. If the Emperor did not perform his duties well and caused the people of Great Zhou to suffer, he would definitely kill the Emperor.
To He Lianfang, even though Prince Yi Yong was dead, the establishment of Great Zhou could not be separated from Prince Yi Yong. Most importantly, the name "Zhou" for the nation was chosen by Prince Yi Yong. "Zhou" was also Prince Yi Yong's hope.
To protect Prince Yi Yong's hope, He Lianfang would never allow Great Zhou to fall into chaos. Although he wished to kill the Emperor, he had to admit that the Emperor had done quite well over the years.
For Prince Yi Yong and for the people of Great Zhou, He Lianfang temporarily spared the Emperor's life.
