The shaking continued for over two minutes before stopping; when everything returned to calm, Chen Ke looked at Wang Ailin and asked, "Does this sphere... just spin around for fun sometimes?"
"No... this is the spherical containment site's self-sealing mechanism... in the event of a containment breach, if no manual intervention is detected, the final self-sealing program will be initiated..." Wang Ailin explained.
