That night, Du You and the others didn't sleep either. After coaxing Xiaobai away, Du You and the two sisters watched reports sent from various places in the underground chamber, alongside multiple screens.
This place full of a sense of technology had never been seen in this world before, but now they had already completed it.
After a long period of learning and research, the three of them now grasped knowledge that had reached tier seven levels. It can be said that if given suitable materials, they could even produce weapons rated at tier seven.
As for tier eight, that was impossible. Only the evolved life forms of technological weapons could reach tier eight. Du You still couldn't reach the level of creating such life forms, so he could only rely on luck.
For example, that special Mechanical Emperor under Du You was a case like this. If not for his good luck in encountering it, it would've been impossible to produce something like this regardless of how much time had passed.
