Now that Prince Nanping has obtained the fragment, it's possible he killed to keep it secret out of an unsettled heart. After all, the Mo Family played a trick on him in front of everyone, costing him thousands of taels of silver. This is a blatant show of disrespect to him. With the power he wields, he wouldn't hesitate to eliminate a few Mo Family disciples, and he directly ordered a hit.
This was the initial speculation when everyone first heard about the murder case. With Prince Nanping's involvement, Lord Feng would find many matters hard and binding. Lord Feng himself has been pushed to the forefront of controversy. He probably had no other option but to seek Gu Yunzhi's help.
Gu Yunzhi, as Lord Feng's friend and confidant, assisting him in times of trouble is quite normal. However, this dragged Tang Wanwan onto the pirate ship as well.
