The situation on the northern expedition army's side was not much better. More and more people had used up their Clean Stones. In the next half an hour, more than a hundred teams were destroyed.
This was not the problem of the northern expedition army. The main reason was the lack of Clean Stones and the lack of sustainability of the battle.
In just one and a half hours, more than 300 million Clean Stones had been consumed. Plus the previous consumption, nearly half of the Clean Stones of the northern expedition army had been consumed.
Of course, the large consumption of the Clean Stones and the deaths of the cultivators of the three parties were exchanged for the deaths of nearly 20,000 Bloody Hand Mine Devils.
Han Fei calculated with his fingers. So far, they had killed more than 30,000 Bloody Hand Mine Devils. Including the number of Bloody Hand Mine Devils he and the Demon Vanquishing Tree had killed before, almost 40,000 were killed.
