When the crustal movement is at its most intense, the urban underground structure becomes extremely unstable, and large-scale subsidences often occur everywhere. Jason was ordered to investigate deep underground, and found that a large area of ​​​​cavity had formed in the strata 60 meters underground in the city. The entire city is in a state of suspension. Once it collapses, it will be a devastating disaster. An earthquake measuring 10.5 on the Richter scale struck the west coast of the United States and Canada. A large part of the land was swallowed up by the ocean, and aftershocks and tsunamis intensified the severity of the situation.
