Ji Ning thought of when Ye Xingyan had also mentioned a related topic before, and asked, "How much do you know about the technology before the chaotic times?"
But Ye Xingming found it somewhat difficult to speak on this subject. After pondering for a while, he sighed.
"Sorry, not much. More than thirty years ago, the research institute was deliberately set on fire. Many valuable documents were destroyed, and now less than one-tenth of them remain. I learned this from my brother..." Here, Ye Xingming hesitated slightly before awkwardly mentioning the name of the Ye Family's S-Class fugitive.
"Saw some documents from Ye Xingyan. One of them was about the plan to build a space fortress before the chaotic times..."
Ji Ning, who came from the chaos, was relatively lacking in aerospace knowledge, and hearing this information was a first for her.
