Professor Zhuang Zichang of the Bit Institute and his son Dr. Zhuang Ning accidentally intervened in the visit of the latest generation of intelligent people from the extragalactic galaxy base to the earth from the graduate students of the "Heaven and Man Unity" program. They discovered the plan of Da Honglai of the extragalactic base to detonate the earth for private purposes. Dr. Zhuang Ning contacted Fufeng through the grooved ring left by the extragalactic homo sapiens, and joined forces to save the earth on the last day of July.
