(Transmigrate + Future World + One or Two Heroines? + Light Ensemble Cast)
The former cosmic civilization fell. Its technological ecosystem planets lost their maintenance and became desolate and barren.
The primitive ecosystem planets preserved the seeds of human civilization under the care of the Three Supreme Systems.
Countless technologies left behind by the previous civilization lie buried on abandoned planets, where intelligence cannot be put to use.
Using nanotech and atomic-level interference, in conjunction with the Chaos System and precious spirit-energy metals, pursue stellar technology with the physical body, replace intelligence with the nervous system, and seek mechanical ascension as you explore the boundless universe.
On Blue Star, Zhao Qingxuan uses the merits of karma to transcend mortality with his soul.
Following a tunnel that appeared amid a distortion of space, he accidentally arrived at a martial arts school in Donghuang, on Tianqiong Star, a place left behind by a senior fellow disciple he'd never met.
Oh, and there's also his stunningly beautiful daughter.
