After a Thousand Years of Sign-Ins, I Was Unearthed

Jiang Chen, a man from the twenty-first century, opted for human cryopreservation because of his brain cancer. He never expected that he'd be frozen for a thousand years.

From the moment he was frozen, he became bound to a daily sign-in System, using what little consciousness he had left to check in.

He remained that way until he was unearthed a thousand years in the future.
