New Youth in the Battlefield

In the parallel time and space of 1937, artillery fire tore apart mountains and rivers. Senior high school students Lin Yuan, Li Weidong and Zhao Xiaoman fell from the white light of the memorial hall and fell into a trench where guns and ammunition were scarce. The chemistry class representative sniffed the black powder and said, "The ratio is wrong." The physics class representative picked up the iron pipe and said, "I can calculate the ballistics." The squad leader opened his notebook and said, "I will distribute the ammunition." When the enemy approached, three pairs of hands covered with chalk dust began to grind the first gunpowder of this era. Knowledge is never just for exams - it is the only fire in the dark night.
