Ling Zhenfei was taken aback, so that's how it is. It seems the Zhou Family indeed has some capable people.
The three of them reached the entrance, and the door was wide open. Fellow Li stopped first and said to Fellow Zhu and Ling Zhenfei, "How about I go in first."
Ling Zhenfei was puzzled, not knowing what was special about this situation, but upon closer inspection, he found that there was a spiritual energy on the door. To enter through it, a certain amount of spiritual energy was necessary.
If the spiritual energy of a person is very weak, it would be impossible to enter.
Fellow Li reached the entrance, used a little spiritual energy, and squeezed in. After a slight collision with the spiritual energy, Fellow Li successfully squeezed in.
Fellow Zhu glanced at Ling Zhenfei and said, "This time the spiritual energy gate has slightly strengthened. Fellow, you'll need to work harder."
