Luo Zheng curiously rushed inside to take a look, and it was indeed an inner chamber. It was as large as a basketball court and about ten meters high. The surrounding cave walls were full of sculptures and murals, about three meters off the ground, depicting scenes that were incomprehensible. The sculptures resembled lamas, and candleholders held thick, arm-sized candles, numbering in the hundreds, illuminating the chamber brightly.
The floor was entirely made of slate, very flat, clean, and shiny. Around the cave walls were many bookshelves, about one and a half meters high. It was unclear what kind of wood was used to craft these bookshelves. They looked quaint and were accentuated by intoxicating incense. Various clean and ancient-looking books, many of which were thread-bound volumes and parchment scrolls, were placed on the shelves.
