Uncle in the World of Immortality

In 2017, when I was seventeen, I was hit by a truck and had been in a coma for seventeen years. My uncle woke up. The uncle who woke up kept muttering about the system, the fairy world and so on. He thought he had suffered a head injury and was mentally disturbed, but unexpectedly, a blue light flashed from his palm, and the entire hospital was instantly blocked. "Hmph! Seventeen years in the human world, one hundred and seventy years in the immortal world, one hundred and seventy years in this immortal world, I am back."
