Yun Tian and Yun Lintian gazed at each other for a long time. They had almost read every book here. The information they were looking for didn't seem to exist here.
Suddenly, they turned to look at the staircase in the distance.
Without further thought, Yun Lintian and Yun Tian walked toward the staircase and tried to ascend. However, they suddenly found an invisible barrier blocking their path to the second floor.
Yun Tian summoned the crown, but his actions were futile. The barrier remained unmoving.
"Let me try." Yun Lintian spoke and then stepped forward. Although he couldn't use his divine energy in this place, he could still sense the crown within his body.
Yun Lintian reached out to touch the barrier, and it immediately disappeared.
