Bab 1539: Yeah, I know

Back in the underground area, Rean was told about the intricacies of the formation and how the cultivators and demon beasts there planned to make it work. Only with that could he finally get the full picture of the thing. 'It's quite obvious that they lack the necessary knowledge for formations. They had to combine many formations together to obtain the result of a single more sophisticated one. This kind of thing is visible everywhere in the formation.'

However, he had to praise the people there for their ingenuity. He understood why it took thirty years to get to this point. That's because they didn't have the knowledge to make things like this. They had to discover everything on their own. 'If I was here thirty years ago with my knowledge right now, it wouldn't have taken more than three months to get the same result. Then again, I don't know if I could do what they did if I was in their shoes.'
