With the intervention of the state, it becomes very difficult for these people to evade capture. Moreover, they are unfamiliar with the advanced technology Earth possesses and are unlikely to have any awareness of it.
After the state took action, the effect was quite apparent. Soon, the satellites locked onto a group of people from the Foreign Realm, heading straight for the forest where the Seal was left.
It seems they are aware that the Seal has been restored and they wish to return to destroy it, to release more people from the Foreign Realm.
Also, it is speculated that they have means to communicate with each other; otherwise, they couldn't have gathered so quickly.
However, they didn't gather all their people, leaving a small group behind, possibly fearing this operation might fail.
It appears there is a commander among them, and their tactics seem very clever.
