Zen keeps leaping to the higher place while dodging the falling pieces of dark cloud and eventually reaches the top of the highest cliff nearby. He, afterwards, sets the arrow and draws the bow then aims the arrow at the devil core. The devil core of the devil king is not small but as standing at a distant place from the core, it looks only the size of a kid-playing ball. Moreover, the floating numerous dark clouds makes the aiming more difficult. It's unlucky that Zen's left eye is his "aiming eye" so even though he keeps blinking, there is no clear sight of the devil core before his eyes but a bloody-red, blurred image.

童战一面闪避暗云碎片，同时往高处跃，来到了附近最高的一处山崖上，弯弓搭箭，对向魔核；天魔的魔核不小，可是童战站的位置离魔核颇远，所以在童战看来，魔核不会比一颗小女孩玩的球更大，而且中间还隔著无数游移的暗云，更使瞄准困难，偏偏他受伤的左眼，是他的&瞄准眼&，他拼命眨著眼，但是总看不清魔核，只看见一片血红模糊的影像

Because iron is recognized the major constitute of the Earth's core, and the Bloch-Grüneisen formula holds true in the solid-liquid mixed phase region, the electrical conductivity distribution in the Earth's core was calculated by combining with the temperature structure of the Earth's core with the PREM model. The electrical of conductivities of the Earth's core vary from 4300Ω〓cm〓 to 8400Ω〓cm〓, and increase with the pressures or depth.

既然Bloch-Grüneisen公式被证明在地核的温度、压力条件下及铁的固-液混合相区仍然有效，对于主要成分由ε-铁组成的地核，就允许用Bloch-Grüneisen公式并结合地核的温度结构以及PREM模型计算整个地核（包括液态外地核与固态内地核）的电导率分布。
