Summoned to Another World, but I'm an Immortal Emperor

[Eastern fantasy + Immortal Emperor returns + travel across multiple worlds + System + cultivation + no female lead]

One night during his vacation, Han Ling was cycling along a mountain highway when a hundred-ton truck suddenly barreled straight toward him.

Han Ling immediately leaped to the right, never expecting to pass through a tunnel and lose consciousness.

When he woke again, he found that he had transmigrated to the cultivation world…

In the cultivation world, Han Ling lives by three principles: use teammates as shields, run when you can't win, and keep a low profile whenever possible.

With his heaven-defying aptitude and astonishing comprehension, he eventually becomes an Immortal Emperor.

Unexpectedly, after obtaining a Saint's Dao Seed, he is set upon by multiple Immortal Emperors.

In the end, he uses so much power that he turns back time to an hour before he transmigrated to the cultivation world.

After his vacation ends, he returns to school, only for another change to occur. This time, his entire class is summoned to a world of magic.

There, he sees all kinds of strange buildings and learns about a new power: magic.

With the Yin-Yang Dao Seed's help, magic can also be refined into pure Yin-Yang spiritual energy.

What's more, he discovers an intelligent “storage bag” that its original owner seems to have called a “System.”

This “System” contains many treasures. Its magical materials can be converted into vast amounts of spiritual energy for his cultivation.

But the more Han Ling investigates, the more he discovers that the “System” has another secret…

And so, Han Ling begins his journey to the top again, in one world after another…
