Chapter 231. Siege

  The soldiers in charge of guarding the city ran over to report. They had already expected the Tartan soldiers to come for revenge but did not expect them to come so quickly! Everyone's expression was solemn.

 The soldiers did not bother to eat. They all picked up the weapons in their hands and prepared to fight. Cheng Yu ordered, 

 "Prepare the rocks and rolling wood."

 The men had gone to the city gate to guard it. Su Qing brought the girls to the toilets to dig for saltpeter soil. She wanted to make black gunpowder. No matter how powerful the Tartan soldiers were, flesh and blood could not withstand her explosives.

 The ratio of black gunpowder was one nitrogen, two sulfur, and three charcoal. Su Qing did not need to make too much black gunpowder now. She needed to intimidate the Tatan soldiers and buy some time for Mo City to catch their breath.
