Three days before spiritual qi revival, an observation panel appears in Shen Lü's mind, showing him the spiritual particles in all things: the weak points of fierce beasts, the success rate of cultivation techniques, and the sincerity or deceit in people's hearts.
While others risk their lives to cultivate immortality, he treats cultivation as a research project. If the panel says the success rate is 97%, he acts. If it says 51%, he turns around and leaves.
On the night the whole city goes mad scrambling for opportunities, he's following his evacuation plan.
Then one day, a starship from an interstellar civilization hangs above the moon, and all of humanity looks up in awe. The panel slowly refreshes with a new line: [Observation target: Unknown civilization's fleet. Success rate: Unknown.]
Shen Lü sets down his teacup. "Then I'll keep my head down until the day I can calculate it."
