There was another explosion, and this time Qiao Xuejun heard it more clearly.
And along with the loud noise, a white light suddenly flashed in front of us, illuminating the hillside in an instant. The raindrops were reflecting the light. It was an explosion.
It was the Hongmei Mountain in front. Is Zhao Xian blasting the mountain?
No, why is he not sleeping at night? Blowing up the mountain? What on earth is he doing?

Qiao Xuejun walked to the living room, put the bowl on the table, and returned to the planting area. She found a basin and washed her hands with water. The water here was brought from the underground well and could be used for washing temporarily. There was also drinking water in the warehouse.

Soak the iron nails for a few hours. If red rust appears, it means the acidity is too high and it is highly corrosive.
To control the variables, she also got another bowl of clean water and put small nails of the same model in it.
