At that tail of the warhead, the drag armour-piercing firebomb is filled with a drag agent and a fireagent, Under the pressure of propellant propelling warhead, it will spontaneously ignite to produce open flame, So it can break through the oil drum and ignite or detonate the gasoline. However, the old-fashioned traced armour-piercing firebombs have obvious trajectories due to traced light when they are launched. Therefore, it is very easy to expose oneself while pointing targets to friendly forces. Therefore, the new tracer armour-piercing firebombs now equipped all start to burn and emit light only after the projectile flies out of the muzzle for a certain distance (the generally set safe distance is 100 meters, which makes it impossible for the enemy to judge the firing position with tracer ammunition, while targets within 100 meters do not need to be indicated by tracer), The principle is generally to ignite the tracer and combustion agent carried by the projectile by accumulating the heat generated by the warhead's friction with the air after flying for a certain distance to a certain extent.即将升入高三的飞毛腿杨夕在追赶“偷车贼”的时候被化学实验爆炸的冲击波伤了腿，没法参加可以高考加分的长跑比赛。开了学杨夕又发现害自己受伤的男生居然转学成了自己的同班同学，还抢走了她想要连任的班长之职。而这个少年正是花彪，一个热血、仗义、勇敢的理科天才。……走吧。秋雨越发急了，淅淅沥沥下个不停，将大街上的鲜血冲成溪流，流入水沟。只是那紫衣少女并非不知断水剑的名贵之处，为何仍要坚持赠与自己呢？仅仅只是为了报恩？高易沉声道：公子可曾想过，虽得了一柄宝剑，百鎰金，只怕是惹祸上身啊。德布拉甘萨回首望向墙上的肖像，曼努埃尔一世依然那样看着自己。
