Cultivation to immortality to the point of exterminating humanity?
Then I choose photosynthesis!
Shang Zeng accidentally discovered the biggest scam in the world of immortality:
Reiki = carbon dioxide
Demonic energy = oxygen
The so-called cultivation of immortality is just a lie to rob the right to exist.
So she decided:
Pattern chlorophyll into blood vessels
Let the robotic arm bloom a flower
Turn the Tower of Babel into a giant potted plant
Motto: Good people are rewarded
