Possessing Immortality and Time Travel, but Setting up a Thousand-Year Dead End

My name is Chen Mo, and I am an immortal. Immortal, immortal, invulnerable, eternal existence. Shen Gui and I were originally the last pair of tombkeepers at the Time Tomb. After a period of guarding the tomb, I became a container of time, and he became a traveler of time. He can travel through time and space, but he is only a mortal and cannot live more than a hundred years. I can live forever, but my body is like a rare treasure, destined to be coveted, captured, and dissected by the world. He never said anything about protecting me, he only left one sentence: "Don't look for me, don't trust anyone." Thousands of years later, humans stepped into the interstellar space, and I was captured as the ultimate experimental subject. The moment the scalpel fell—— The thousand-year deadlock he had laid out suddenly began. Want to study me? Can. First, the entire civilization will be buried with it. I am immortal, and he has laid a plan of death for a thousand years. This round is set up for me and for the world.
