Liu Dong is a researcher at the East China Sea Branch of the China Maritime Administration. He accidentally discovered a special energy wave during a tsunami in 2004. This wave reappeared in the J country tsunami in March 2011, and led to the death of scientific researchers working under the sea at the time and the explosion of the J country nuclear power plant. The source of this wave was the Mariana Trench. China attaches great importance to this matter. Based on the analysis of unidentified objects photographed by the Ministry of Defense in the trench in previous years, it is believed that there are unknown highly intelligent creatures at the bottom of the trench.

A sea-exploring boat unexpectedly encountered an unidentified flying object deep in the trench and started a fierce battle. The captain ordered armed personnel to cover the retreat of the scientists. However, Liu Dong did not want to miss this opportunity to make contact. He drove a private escape capsule and followed the unidentified object into the NZ Star trench base with his colleagues.
In the base, Liu Dong met a girl he had rescued a few years ago, and this girl was Wang Na, the princess of the NZ planet. Liu Dong solved many doubts and learned about the aliens' plan to wipe out mankind...
Wang Na died while rescuing Liu Dong from the base. However, when Liu Dong returned to China and was about to inform the Minister of Imperial Affairs of the alien's conspiracy, the alien's space eggs had already been placed over nuclear facilities around the world...
