Chapter 13 end

Perhaps, there are still some doubts that must be mentioned, such as the circumstances under which those granite stone foundations were built, and who built them.But in this respect, it can only be settled by conjecture. My guess is that Ruan Yao's great-grandfather met "them", and "they" gave Ruan Yao's great-grandfather some benefits (the reason why the Ruan family suddenly became rich), and Ruan Yao's great-grandfather agreed to close the "them" This deep hole makes the existence of "them" never be discovered.And "they" also have some kind of power to protect "them" themselves, and Rollo may know this, so there are some dangerous marks on his map.

If it wasn't for Wu Zijun's commission, and if it wasn't for Luo Luo's in-depth investigation, then no one would know about this matter forever. What I don't understand the most is why Luo Luo kept everything a secret before he died. So far as I can speculate.
