The Therapy System Is Declining, the Therapy System Is Demonstrating

[Starry sky + no heroine + superpower + underworld ability] In the Starry Sky Era, everyone wants to leave their name in this endless starry sky. Lian Chen was helpless because he was a healer, but his healer was declining! Moreover, the ability given by his system does not seem to be reliable. Congratulations to the host for completing the choice, taming Rhubarb, and gaining the ability to tame. Lian Chen scratched his head helplessly, no, man, what use do I have for raising pigs? Until he saw a group of giant starry beasts nodding and bowing in front of him, he couldn't help but be shocked. Damn, is this okay? Congratulations to the host for completing your choice and gaining the ability to become invisible, but you can only become invisible when others are not looking at you. "No, system, please explain to me, what is the use of this useless ability?" Until later, congratulations to the host for completing the choice and awakening the ability to stop treating others as human beings. Lian Chen suddenly realized, holy shit, there is still a second level! Congratulations to the host for completing the choice, practicing Tai Chi with Grandpa, and gaining the ability of yin and yang conversion, which can convert healing into damage! Lian Chen was shocked. Who said the healing system was weak? I was the first to refuse! In the starry sky, Lian Chen's countless abilities made the foreigners miserable. The alien roared, no, you are a healer, why do you have so many underworld abilities?
