Trap in the making

The emperor left Mo Er Xing well enough alone, however it did not mean he ignored MoQiu altogether. 

He had been in close contact with his father, and his aunt for a really long time. Fa Jing Xuan and Xue eldest miss are his earliest companions. 

There is no way he will not recognize the son of Fa Jing Xuan. 

"One!" he called out. 

A black clad man jumped out of god knows where to right in front of the emperor. 

"At your service, Your grace.!" the secret guard said, kneeling in front of the emperor. 

"Send someone to observe the boy in Er Xing's house.". The emperor commanded. 

"Investigate the backgrounds of everyone in the palace, starting with the oldest ones. Investigate activities of all the princes in the past ten years. Starting with the oldest one." the emperor added, then stayed silent for sometime, as if remembering something else.
