It is the tears of the earth that keep her smiles in bloom.
读书笔记《先知·自由》
深圳这两日雨来得好急，雨来的时候，风也张狂。在广袤的苍穹下，这云，黑压压的云，像几块破布试图阻挡天外排山倒海的进攻。 千军万马奔腾而来，踩踏着大地上的生灵，那风，早已看清了形势，正投身到雨的麾下，卖力的吆喝着。转瞬间，天地已然变成混沌，哪还分得清什么云和雨，云早已倒戈相向，朝着大地疯狂的攻击。唯有雷，从天上直到地下，簌簌的撕裂时空，天空已是破败不堪，摇摇欲坠。多狂妄的雨啊，认为自己必胜的雨，毫无顾忌的践踏，想着把天地间的一切摧毁。可是，它万万没想到，躲在云后的太阳，伺机而出。用他千万道光编织而成的无边长带将雨狂卷摔远，将千万道光束成一柄长矛把云击得粉碎。呵，那雷，吓得不敢发出一点声音，风躲在树的后面颤颤巍巍。我抬头望着他，看到他那无边的力量，缠绕在山川，融化在土地，弥漫在天地间。知道他一直恪守他的承诺，坚持他的守护，从未离开，一直都在，无可战胜！
