To put it simply, it is a story about time travel to the future - I have read so many time travel articles, but few of them are about traveling to the future, so I decided to make a living by myself~
After all, the future is unpredictable~ So such a thing is possible~
Looking at Selina who made such a promise, Zhang Ze knelt down on one knee. Although this is the inevitable trend in what happened, I will let you bear such a heavy burden... "I, Zhang Ze, hereby establish a contract with Siren Salina Renshi. Before I die and return to the original time and space, I will make Siren Salina Renshi the king of all mankind, assist her in unifying the galaxy, and protect her and her knights' safety. I swear here!"
——The above has already shown what the story is...
There is yy (this is inevitable), there is GL, and there is BL, so I really don't know the classification (looking at the sky)
I originally wanted EG, but unfortunately I found that EG was incompetent, so... O(╯□╰)o
Having said that, I was really fed up with those time-traveling stallion stories, Mary Sues, etc., So I decided to do it myself~
