Ace kept reading the Leap Queen's stolen memories in sequence.
Suddenly a frown surfaced on his serene face because from her memories he discovered the Lighting Treasure wasn't in the treasury since this woman has been there many times and only the King know where it was.
This means the treasure was with the King or hidden somewhere else in the Leap Palace.
Ace couldn't probe the memories of a Qi River cultivator yet, which made this even more cumbersome. He stopped using soul probing and move south, deeper into the palace.
He was going toward the King's Library, where the King would be at this moment, according to the Queen's memory.
Ace encounter some empty Qi river royal guards, but he easily flickered past them.
After crossing a big corridor, a tall silver door came into his view. This was the King's Library where only the Leap King can enter, not even the Queen can enter this place without his permission.
