The System Wants to Be My Taoist Companion!

My name is Zhang Erhe, and I am a modern person. Like most protagonists, I traveled through time because of an accident. But what is different from other novels is that my good pigeon, Fatty Bai - Bai Yunfei, traveled through time with me. The strange thing is that he actually has the system of the protagonist in the novel, but I have nothing... ------ Wait, something's wrong! I seem to have a 'system' too, but it's a bit strange.... She said I was her Taoist companion, and every time she showed up she wanted more and more... Stop talking, she is calling me... Madam, here I come (*^▽^*)! ! !
