As hunger drives people into depraved struggles, Ling Xiao feels trapped in hell. He builds an innovative tech company that purifies water and invents compressed biscuits, restoring normalcy to life. He awakens people to protect the environment, solving problems through science. No matter the darkness, rain will eventually clear to reveal a bright sky.
