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.讲述一副神奇的画卷从几百年前流落到现代，没有人知道这幅画卷的秘密，拍卖行准备以古董拍卖。但是一名博士从古文书中得知了这副画卷的神奇之力。万元刚将一大捆山芋藤拖去地头埂，好让人挑走，转头就见奶奶又来了，还打得妹妹跟弟弟哭泣不止，顿时，他眼里迸射出阴沉的光芒。(12.27 update)讲述了三个小伙伴翘课去网吧打游戏被泼辣的女班长抓了个正着，回家路上拐去碟片店闲逛时收到了美艳的女老板娘递来的神秘游戏光盘，然后被吸到了一个可以自由上线下线的三次元游戏空间的故事。然后呢？然后看了就知道了嘛！
