Chapter 4178

Yukinoshita Yukino: "And the most terrifying thing about Doraemon's world's time machine is......... using it to casually rewrite history, it's totally fine."

Osakabezaka Taiga: "After all, the scientific concepts are different...... Doraemon's scientific concept is, no matter....

No matter how the process changes, the final result is always the same.

Other worlds' scientific theory, on the other hand, is the butterfly effect."

Gudako: "Real!"

Satan: "... I'm very curious, if we say Butterfly Kanae came to this era! Then between Butterfly Shinobu and Butterfly Kanae now, who is older?"

Satan fell into deep thought, he felt this was a very serious question.

Hatsune Miku: "...... You are... a logic genius"

Ryuuguu Reina: "Too showy...... this question, for a moment I was actually at a loss for words."

Doctor Roman: "Stay calm, Young Lady Huang Rong even met Mr. Zhang Sanfeng who was over a hundred years old.

And in Young Lady Huang Rong's current era, Zhang Sanfeng might not have been born yet, or was still in his childhood."
