Sign-In Begins with Immortality

I transmigrated to the Tang Dynasty, but this Tang Dynasty is no ordinary one.

The Immortal Dao flourishes, and a single sword can break ten thousand arts.

The Martial Dao thrives, using martial might to suppress demons and evil spirits.

From the start, I sign-in to obtain the Eternal Immortal Body.

I possess an endless lifespan, destined never to die.

But demons and monsters are slaughtering the common people.

Should I lie low and become an immortal, or tread across mountains of demon corpses and slay monsters to prove the Dao?
