Qingfeng and the others all entered the enormous palace to search for treasures. Some of the treasures were placed in the middle of tables while others were placed ontop of chairs. Some were placed in secret compartments behind the walls.
There were secret mechanisms that one had to solve in order to open the compartments behind the walls. Some other treasures were placed in the rooms and protected with passwords and mechanisms.
Even if one managed to bypass the Monarch grade formation, one still had to use some methods to obtain the treasures.
Qingfeng did not go for the treasures within the large hall as they were Monarch level techniques, which were unattractive to him.
Qingfeng was currently practicing saint and immortal level techniques which were much more powerful than the techniques within the hall.
