Du Ge confidently walked through the gates of the Homeland Defense Bureau headquarters, blending in with a group of staff members. The on-duty mecha pilots didn't even glance at him.

As long as Du Ge didn't reveal himself, no one could detect his presence or abilities. When he was still, he was invisible to others; when he moved among people, he was the most inconspicuous as long as he kept silent.

The Homeland Defense Bureau was bustling, with guards stationed every few steps, all wearing light mechas. Walking through the Bureau, Du Ge felt like he was in a science academy.

Here, he was completely cut off from the outside world; even in the corridors, he couldn't sense what was happening in the rooms on either side. This effectively prevented Alien Star warriors from spying on or harming each other.
