Feng Chengyuan's mental power is at double S level, while Feng Yaoyao's mental power is less than A level. If it were in the past, it would naturally be very easy to use this method, but Feng Chengyuan's current situation is simply unable to withstand the consequences of such wanton use of the mental domain.

This is also the reason why Butler Wu is so anxious.

Butler Wu was ready to take over Feng Chengyuan's position and control Feng Yaoyao at any time. However, Feng Chengyuan had no intention of releasing his spiritual domain. Instead, he looked at Feng Yaoyao with a serious expression as her spiritual energy became more and more violent, and a hint of deep thought flashed in the depths of his eyes.

It seems that this is the only thing we can do.

A thought flashed through Feng Chengyuan's mind, and after a brief consideration, he finally made a decision.

At the same time, Yun Miao stayed in a safe enough place, looking at Feng Chengyuan, Butler Wu and others nervously, feeling inexplicably nervous.

Now Yun Miao is no longer the ignorant time traveler Xiaobai. She has learned a lot about this world and can see that Feng Yaoyao is in a state of mental chaos.

Yun Miao felt that the reason why Feng Yaoyao was like this might be because of the mental hypnosis she had just performed on her. She had thought that Feng Yaoyao would be scared to death, but she did not expect that her mental power would actually go into chaos?

In that dangerous situation just now, if Feng Chengyuan hadn't activated his spiritual domain in time to cover Feng Yaoyao, she would have been injured by the violent energy before Butler Wu could take her away...

Yun Miao looked at Feng Chengyuan who was so close to danger at this moment, and silently clenched his hands. For the first time, he was so worried about Feng Chengyuan's safety.
