Let's Do It The Ace Way.

After an entire day of discussion, the high council of the citadel agreed to Shi Lang's proposal, and they invited people from the Federation to help them with the array inspection. Shi Lang called for a batch of array masters. These people had gained a lot of proficiency when dealing with arrays. 

Shi Lang was not placing any stakes on these people. He had only called them over to show them the immensity of the cultivation world. He was well aware of the arrogant attitude developed by the masters of these alternative professions. They all looked down on those without sufficient strength. He did not want that to happen in this era too. So, Shi Lang called them to show them how little their knowledge might be.
