She Will Be the Strongest in the World, but Sometimes I Am Stronger

[Single heroine, superpower, rebirth, two-way protection, two strong, urban system] In a city abandoned by spiritual energy, two students with no connection at all were dreaming of the same dream. "I had a dream. In the dream, a girl was holding me and running away. She put me in an orphanage. I don't know what happened next... But the important thing is that my house was destroyed in the blood moon, so I moved into the home of a female alumni." … "I had a dream. I was running away on a rainy night with a child in my arms. I put him next to a building, and then I was killed... Later I found out that there was a boy who seemed very special, and he had no home, so I let him live in my house." … In a new life, the two people who lost their memories met again. "My name is Su Haoyu. Please remember that my emotional state is very important. Don't you understand? Then let's put it another way... You'd better fall down in front of my big number." "My name is Su Xinglan. I have remembered everything. Moreover, I have found him. But this time, his strength is temporarily inferior to mine, so I will protect him like I did in my dream, because he is everything to me." … "Su Xinglan! Be gentle! I can't stand it anymore!" "Are you kidding? Whose landlady will be the strongest in the world...!"
