可惜太多事不能随人所愿。同盟会员秦禾君等被叛徒九爷出卖牺牲。15年后儿子秦玉栋回樟树镇寻找杀父仇人。九爷化名成虞万之破坏樟帮支持北伐征集药材。因爱人是九爷女儿,杀父仇人与爱人之间,秦玉栋艰难抉择……物理天才李斯坦沉迷于穿越时空的研究，在自己的家做实验，成功的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.
