Inside the small building's first floor, there were several bookshelves filled with numerous books, and a few people were quietly browsing or copying them.
Su Xin didn't know which secret manuals were better, so he observed for a while inside the small building.
He silently noted down the few manuals that were chosen more often and their corresponding areas, waiting until the dead of night to reveal himself.
He still had the Information Filtering buff, so even if someone was guarding the small room on the first floor, he wasn't worried about his footsteps attracting attention, as long as it didn't cause a big disturbance, people would instinctively ignore it.
After revealing himself.
Su Xin approached one of the bookshelves and picked up one of the more frequently browsed secret manuals.
"Four Seas Sword?"
"It seems to be a martial technique."
Su Xin casually flipped through it, discovering that it indeed was a sword technique type of martial skill.
