During the day, besides Gu Yanzhi and Song Zhao, everyone else had to go to work and was not at home. This situation was quite troublesome.
Gu Yanzhi took the initiative to suggest that from now on, the three elders should stay on the 16th floor during the daytime, and they should move the large iron gate on the 17th floor down a level to the 16th floor, and also install an alarm there.
This way, even if the bad guys broke through the multiple obstacles outside, they could immediately sound the alarm, which would be loud enough for Gu Yanzhi and Song Zhao to hear the commotion and come down from upstairs.
Even if by chance Gu Yanzhi and Song Zhao were not at home, the iron gate could still hold back the intruders for a while.
No one delved deep into where Gu Yanzhi got so many materials from. At this time, when someone was willing to share their belongings without seeking anything in return, it was not something to be suspicious of.
