Fifteen minutes later, Feng Xuan brought him to the Chronospace Jade Walls, and Li Yun was a little surprised by what he saw. There was not just one jade wall but sixty of them.
Each massive wall was made of smooth jade and covered in intricate images, and every one of them represented a different low-level secret technique. Several cultivators sat beneath each wall.
Some walls had only a few people studying them, while others had more than a dozen. All of them sat with their eyes closed, completely absorbed in comprehension.
Li Yun began with the first jade wall. The secret technique recorded there was called the Crimson Slaughter Mark, and it was designed specifically for long group battles. For every ten enemies a cultivator killed, he could condense one blood mark inside his body.
