The paintings were rolled up and put together.
Sean Knight didn't even look at them directly. He put all the ancient books here into the spatial realm, including those paintings.
Then he walked to the wall opposite the door of the Side Palace.
A painting of the "Cold River Fishing" was hung on the wall, nearly blocking half of it.
Sean Knight carefully took down the painting, rolled it up and put it into his bag, then began to study the wall.
Of course, this wall was not ancient, nor was it moved from China, but behind the wall, there was another story.
The reason Sean Knight opened the eastern palace door first was to let him stay there, otherwise, it would be difficult for him to explain here.
After studying for a while, he found the door opening in the corner of the wall. He twisted a slightly protruding brick at the wall corner, and the wall slowly moved, revealing a hole large enough for a person to enter and exit.
