Spiritual Qi Revival: My Sandbox World

In the age of spiritual qi revival, humanity is wiped out by the demon race.

Yang Yunkai is reborn and gains a System. He explores other planes, develops their civilizations, and receives the fruits of their progress and energy in return.

Technological civilization? Martial arts civilization?

Magic civilization? Battle qi civilization?

Martial soul civilization? Cultivation civilization?

Insect civilization? Elemental races?

Why not try them all?

Technological data, martial arts techniques, magical skills, cultivation arts...

Once, something precious and sincere was... right in front of me.

Now, I hope for... something for nothing!!
