After Wu Tianfu stayed in the valley for a while.
He then left.
The reason he didn't kill Wu Yuexin is because she is a direct descendant of the Wus, with a special restriction in her body.
If Wu Yuexin were killed, Wu Chengyan, who is in a dormant state, would immediately be aware, and with Wu Chengyan's methods, he could determine who the murderer was. That is why Wu Tianfu didn't kill Wu Yuexin.
As Wu Tianfu's figure drifted out of the valley, he waved his arm, causing the entire valley to tremble slightly, while an energy wave spread around. The entire valley was instantly enveloped in a layer of energy, and if anyone tries to break this energy barrier, Wu Tianfu would immediately sense it.
Ye Chenfeng was hidden behind the big rock at the mouth of the valley, with the help of Old Bai and Old Hei, even if Wu Tianfu passed by the rock, he wouldn't detect Ye Chenfeng's presence.
After Wu Tianfu had left for several tens of minutes.
