For Ruan Ming, this may be the best ending.
Under the influence of space radiation, his team members passed away. The remaining fuel of the spacecraft could not support his return. The food was only enough to sustain him for three years. The cultivation of the new amoeba had not been completed. Everything was so unprepared.

Intention: The sinking of reason in loneliness and absolute possession.
