Fang Zhou, how did they see me?

Good news: Bai Yuan traveled through time and retained the memories of his previous life, which is equivalent to living another life, and in this world full of girls with animal ears.
Bad news: There seems to be some problem with Bai Yuan's time travel. He and all the people in this different world called Terra seem to be in a different dimension. He can see other people, but others cannot see him, touch him, or communicate with him.
But Bai Yuan has awakened the [System]. Bai Yuan only needs to bind an agent to walk on his behalf in the real dimension and spread his legend throughout the world, and then he can use the power of faith to completely appear in the real dimension.
However...
"No one saw me at all!! I can't bind an agent at all!!"
Lu Yuan, who had been wandering in this city called Longmen for five years, roared at the top of his lungs.
Just when Lu Yuan was completely desperate.
A senior police superintendent named Shi Huaiya accidentally saw him.
Good news: Some people can see themselves.
Bad news: I'm now lying in her bed, being mistaken for a pervert, and she refuses to be my surrogate.
