The construction took place more than six years ago.
When the society developed too fast, people, things and relationships would undergo drastic changes. It was an uphill task to find out those who had been involved in the construction project.
Huo Shan indicated that he did not keep in contact with the original subcontractor for the concrete masonry portion. Even the documents back then were no longer kept for records.
Bai Muchuan sent a detective by the name of Xie Hui to make a trip to the Urban Redevelopment Bureau to get the records of the construction project of "The Palace", while Tang Yuanchu took the task of finding Sun Shangli's lover.
Huo Shan's understanding of that man was only the name and that he was Sun Shangli's college classmate.
So Tang Yuanchu decided to start investigating from the college.
Sun Shangli was a native of Jin City while she went to college in Shan City.
