Nobel developed explosives for two reasons: first, Nobel, who was 26 years old from 65438 to 0859, returned to the motherland and was anxious to see the current situation of manual labor, which was "both bitter and slow"; Second, the power of black explosives at that time was small and it was very unsafe to use. For these two reasons, Nobel is determined to develop a powerful, safe and reliable explosive.
