Chu Mo's ambition was never concerned with power, status, or fame. It's not that he was so lofty in his aspirations; it's just that his goals lay elsewhere.
However, he did not mind Chu Chu having such ambitions; whether she was his sister or not, she was clearly his closest soul mate in this world. Chu Mo initially considered whom to push forward to establish a force, similar to Piaomiao Palace during the Yanhuang era. He simply did not want to be in that spotlight. Chu Mo had considered Zi Dao but eventually abandoned it because Zi Dao was a traitor to the Luoshui Family.
It is believed that no matter how broad-minded the Luoshui Family is, they could hardly tolerate such a thing.
Chu Mo also considered Gu Bingbing; if there was really no more suitable candidate, Gu Bingbing could be an option. However, her experience was still somewhat limited, and her desire to break free from the Ancient God Family would likely be challenging.
