Researching & Organizing.

Shi Lang and Shi Tao jumped into the void tunnel that led them directly to the Citadel. However, when the two arrived at their destination. Shi Lang put up his guard and said, "Tao, do not let down your guard." 

Shi Tao sensed something serious in his voice and nodded slowly. The location of their arrival had changed. Shi Lang was unaware of this, but he knew how arrays worked. Earlier, the place was a wide open square; this time, the site appeared to be some hall. Gilded with gold trims and gems studded walls. 

Just when he was about to use his spirit sense to check what was happening, a buzzing noise attracted his attention, and the wall on the left revealed a door-like slit in the middle from which Crystal walked in. 

Shi Lang sighed and asked, "What are you guys doing with the beautiful open square and turning it into a hall?"
