The System Is Late, Give Me a Huge Gift Package

After traveling through a different world for 20 years, the system landed late and unlocked an invincible physique at the beginning, which also came with the cancer debuff. Invincibility is truly invincible, and pain is truly painful. He was punched and coughed up blood, and he had to stay in bed for three days after a fight. I am invincible but I encountered a cancer that has no solution. "Ding——!" "Your system has arrived and you have obtained the super invincible physique of the universe." "Because this system is late, we hereby send you a cancer gift package to make up for the host." "It has been automatically released into the host's body." "No, I will die!" "Host, please trust this system. The products produced by the system must be high-quality. It will not kill you but it may cause a little pain." ? ? ? "Warm reminder: The host will not die from cancer, but the pain caused by cancer is unavoidable and will continue to exist." Am I stuck with a bug? Beat me! No! Others do tasks to become stronger, but I do tasks to cure cancer. I just completed the task, why are these young ladies approaching me one after another.
