Zong Manga: Am I Too Early to Dress up in the Samurai Era?

Due to unknown reasons, he traveled to the age of samurai. With the help of the system, he became the strongest swordsman and became immortal. Of course, when the time came to modern times, the system sent a prompt: "Host, visitors from another world are about to come to this world, please be prepared." Suzuki Yuzhen's eyes turned sharp: "Where did it come from?" "From... Your original world." "... What?" Note: This world is a parallel universe. There is no war between China and Sakura. If I have to say it, it is country r who chose country z between country m and country z because they are cowards. Tsukiyomi Tsukuyomi, the heroine of this book, is cute and has a long life... I can't write about the harem for fear of ruining the story. Please be merciful as a new author. If you have any problems, you can point out any problems and be gentle...
