To Cultivate Immortality at the End of the World, I Choose Mechanical Ascension!

After the Catastrophic Day, zombies and alien beasts ran rampant and occupied the entire continent. In order to survive, humans have established shelters in every corner of the continent. Through research, it was discovered that zombies and these strange beasts all have a strange energy crystal in their bodies. As long as humans eat it, they can improve their own strength. Until it reaches a certain level, you can break your own shackles and become comparable to the gods. As a time traveler, Wu Hao's body was damaged in many places, so taking energy crystals had no effect. When he was in despair, the system gave him a chance to choose. It is to be an ordinary person hiding in Tibet all day long, suffering humiliation and eking out an ignoble existence. Or abandon the body and adopt a mechanical body to gain immortality and powerful combat power?
