Gu Shi looked at Yi Bing when he heard him asked. "Fortunately, Shou Ji and Shi Jiu are there to protect the other departments." He answered when they recalled that Shou Ji and Shi Jiu used some devices that Shou Ji asked his family in the interstellar world to protect the other departments from the enemies by setting up a barrier around the area.
Now that Gu Shi recalled it, it seems that Shou Ji and Shi Jiu also used a mecha earlier. Gu Shi's brow twitched and he noted down to remind them to return the mechas to the other world. One of the reasons for this is to not overindulge the technology of the Stable World or else the Stable World would not be a Stable World anymore.
