This second dimension is too immortal

Zhao Si had traveled through time and gained a system as a trump card. After somewhat calming down from the panic and confusion brought on by the time travel, he watched the immortal flying in the sky with a sword. As a veteran fan of xianxia novels, Zhao Si seemed to see a bright future for himself, roaming the world with a sword.
"Then come out, system!"
"Ding! The Dimension Animation System is at your service."
"?"
Isn't this a fairy world? Why is it an anime system?
"...What kind of operation is this! The style of the painting is obviously inconsistent!"
Zhao Si listened to the system's confident voice and felt surrounded by a huge sense of disharmony. He felt that the road ahead was suddenly full of pitfalls.
But no matter what, even if I travel through endless dimensional worlds, no one can stop me, Zhao Si, from cultivating immortality! I said it! (Convinced)
