Barrier

All the experts moved to guard all entrances of the second prince manor, forgetting the proper courtesy to ask the owner's permission. They did not even question Wei Jiayi's command.

The experts in position, were probably all feeling guilty for slacking off, they formed an arrangement to properly set a large barrier for the whole place, of which Wei Jiayi approved. The blue glass-like barrier was set to block all possible entrances and exits to the manor. 

This type of barrier reached further underground so there was really no chance of escape except flying over it. Adding that up to the original protection barrier in the Second Prince manor, Wei Jiayi smirked. Gao Lan Mei from her previous life had never needed to worry about barriers.
