Countdown to return: 30:00:00.
In City 20, a man with a vacant expression, holding a clip-on hard drive, slowly walked towards the Mental Dojo of Qieshe Yumian.
After Qing Chen's bloodbath, the security level here had already been raised.
Within a radius of three kilometers, there was a sentry every three steps, a lookout every five steps.
Drones patrolled the sky, densely setting up 36 patrol routes.
A garrison force within the city also added a field brigade, and the other two cities each added an independent regiment, strengthening the city's defenses.
There were also over a hundred war robots.
The residents no longer dared to approach here.
From a certain perspective, Qing Chen, with a magic trick and his own strength, immobilized a field brigade and two regiments.
At this time, soldiers outside the Mental Dojo raised their automatic rifles, blocking the vacant-eyed man: "Where's your electronic ID, what are you doing here?"
