Tribulation.

Mitsu called people and told them it is an emergency. Shi Lang was absorbing too much spiritual energy too quickly. Mitsu did not have much knowledge, but she knew that too much spiritual energy intake was harmful to the practitioner. 

The spirit-gathering array was not helping the situation, it was like Shi Lang was a black hole and nothing could escape his grasp. The cottage was shivering, and Amelia used her special ability to come over. She flew so fast that she almost reached the speed of sound. 

She looked at the situation and before Mitsu could say anything, she said, "He is moving towards a breakthrough to reach the peak of the primal soul realm. There will be a tribulation following this. We need to have this place evacuated and none of the soldiers in the base should cultivate when the tribulation is taking place, or it might go after them." 

Mitsu nodded and said, "I will ask Commander Silence to arrange this."
