You take the DNA of the Water Elephant Axioudle Naked Mole Rat and the Medusa Jellyfish and mix them to create a hybrid DNA base. Their features are invincibility, immortality, regeneration and cancer resistance. If you inject the mix into people's body, it will save many lives. With the regeneration, it will let people survive if they have any body issues. Also, the invincibility will let people survive in deep space and without water for 120 years. If you give them to people during a drought, they will survive. Doctors can give ones the hybrid DNA mix so they will survive cancer. The Medusa Jellyfish will restart it's life before dies. If this exists in the future, humanity will be released from cancer and other problems.
