He didn't know who was helping Ye Jian and didn't know if the person helping Sun Yaozu was the same person who was helping him. He didn't know anything he wanted to know!
If he didn't know, he needed to investigate. Since there was no progress after so much investigation, he would change his method.
Just like what Uncle Gen said, Ye Zhifan didn't feel at ease when his position rose so quickly with the help of the jade. He felt that since that person was able to raise him up, he could make him fall too. The great power this person had made him suspect that this person was a high-ranking official in the capital city.
As for Grandma Ye, she was so furious she almost threw the phone on the ground. However, she couldn't do anything to Ye Zhifan. After all, she was the one who needed his help!
