Just as Shenwu Sanlang was fantasizing about engaging the Tang Army in street battles within Beiyuan City, using the infrastructure the Tang Army was reluctant to destroy to wear them down, a sudden explosion came from the distance.
Shenwu Sanlang and his adjutant both stared in shock before rushing to the window, where they saw black smoke billowing from inside the city.
"What's going on?" a flustered Shenwu Sanlang angrily asked, not knowing whether he was questioning himself or his adjutant.
But the adjutant at his side was just as clueless, standing dumbfounded before the window, at a loss for what to say.
He racked his brains to find an answer to the question his general had posed and finally squeezed out a comforting guess, "Maybe, maybe there's been some mismanagement with the munitions or other flammable and explosive materials, it could be an accident."
