Under Yao Huayuan's guidance, Ye Chen arrived at the Spiritual Medicine Mountain's forbidden area.
The so-called forbidden area was actually a mini palace that was developed individually. There were four old men guarding the palace door. Ye Chen scanned it with his Divine Consciousness and found out that the four old men's cultivation bases were powerful. They were approximately on peak-stage Dao Entry.
Such a powerful man would be the boss of an area if they were out in the world, but they were guarding a medicine pavilion now. Judging by that, it was no wonder that the Spiritual Medicine Mountain could hold such a high status.
"Mr. Ye, these four are our Spiritual Medicine Mountain's Pavilion Guardian Elders. Each of them holds a key with them. To open the palace door, you'll need to open it with my key and their keys," Yao Huayuan introduced while trembling. Then, he took out his key and ordered, "Old Qi, please open the medicine pavilion door."
