In order to avoid drawing too much attention in the city, Gu Ling made some explosives and went out of town to test them in a deserted area.
For safety reasons, Su Liang wanted to go too, but he was rejected and did not persist.
Accompanying Gu Ling out of town was old Mu. He knew how fireworks and firecrackers were made and had some understanding of explosives, but the formula Gu Ling used and the peculiar-shaped final products all made him feel very novel, and he didn't know how powerful they were.
Seeing this, Old Mu strongly requested to follow Gu Ling to have a look before Su Liang even had the chance to invite him.
While waiting for news at home, Su Liang talked to Qi Jun about the matters in Xuanbei City brought back by Qi Jiang, mainly about what Qiao Cong and Qiao Jing had done since arriving in Xuanbei City.
