Mo Ci, who was also abducted, returned to Earth with the help of another system with unknown purpose. After handing herself over to the system, she took on the responsibility of searching for her compatriots in another world. As a result, a story of mutual redemption between time-travelers was staged in various worlds. They searched for their compatriots in various planes and brought back various technologies and knowledge, and the country's science and technology advanced by leaps and bounds. And the crisis is getting worse.
