After reading the letter the Emperor was stunned and the crown prince was equally amused as he covered his mouth and laughed lightly.
Su Wan had used so much flattery that it was really amusing to read. The words were lively and interesting and neither the crown prince, Fei Yu Ching nor the Emperor found it annoying and greasy.
" Continue reading, Father Emperor," said Fei Yu Ching as he looked at his father who snorted and then picked up the second stack of letters and started to read, " I know that the Imperial City has never seen something like concrete before which is why I am enclosing its property. Cement is extremely strong and can withstand rain, and erosion of wind and can remain the same for years. It can be used for constructing roads, conserving water by building dams, military defence and many more projects."
