Sci-Fi: After Years of Sign-Ins, I'm Invincible

Lin Fan transmigrates into a science-fiction world where technology is highly advanced.

Fortunately, Lin Fan activates a sign-in System.

No one here believes that immortal cultivators exist.

So...

While they pilot mechs to fight monsters, Lin Fan can unleash mighty divine abilities and wipe out entire swarms.

While powerful warriors with unlocked genetic locks battle, Lin Fan can also attain sainthood through his physical body and roam the world.

When human hosts transformed into giants of light fly into the stars,

Lin Fan crosses the universe with his physical body and soars through the sea of stars.

Scientist: "Everyone, you must believe that immortal cultivation doesn't exist. It's merely a product of human technology."

The crowd: "Master, look! That person is carrying a star on his shoulder and crossing the sea of stars!"
