许半生又笑道：“你这小畜生，说话总是不实不尽的，你口口声声坏道士，若不是我师父传你功法，使你抗拒天劫，你现在早就与这个世界无关了。”
赤兔闻言，略有些羞涩的低下了头，两只小前爪挡在眼前，似乎很不好意思的样子。
“暂时留在家里吧，目前我也帮不了你什么，不过这总是你的一个机缘。或许有人可以帮得了你，又或许过些日子我突破到意之境，倒是有可能助你一臂之力。”许半生将赤兔放在地上，赤兔知道这是许半生答应帮它，早也就知道把握不大，它现在反正也没什么选择可言，能得到许半生一句承诺，心里也自是满足了。
“放心吧，小赤兔，主人至少可以帮你安然渡过天劫。”朱弦对赤兔总是有些心怀歉意，出言安慰。
赤兔点了点头，眨巴眨巴蓝汪汪的大眼睛，头顶那对长耳朵向后耷拉下去。
许半生看在眼里，也是默默的点了点头，朱弦本是个妖灵，除了对自己之外，对其他人其实都没有什么感情可言。如今她懂得怜惜赤兔，倒也是一场不错的缘法。有了爱怜之心，才能够真正算是一个人类，否则，始终还是脱不了身上的妖气。
看起来，这趟让朱弦去日本真的是去对了，至少让朱弦有了仁心，假以时日与其道心结合，她才算是真正的修成正果。
“先且呆在家里吧，朱弦，你随我上楼，替我护法，我要炼制丹药。”许半生走向大门，朱弦赶忙跑过去帮他开了门，又有些不放心的回头看看赤兔，赤兔很懂事的点点头，表示自己会老老实实的呆着。
出了门，许半生又回头说道：“小畜生，这里终究不比你常呆的地方，稍稍做些修行，对你只有好处。”
赤兔知道这是许半生在指点自己，它离开雾岛山的火山之后，的确是各种不适，若非朱弦一路上一直用自己的精气化作火炎，它怕是早就有些受不了。修行当然可以帮助它适应这里的环境，可它总担心修行会使得它遭遇天劫，到时候只怕是得不偿失。所以便一直忍耐着各种不适，现在许半生告诉它可以适当的修行，它才敢吸收天地灵气。
上了楼，朱弦看到楼上原本的聚灵阵之中，又被许半生重新布置过了，想来是为了炼制丹药做的准备。
许半生说道：“放水，我要沐浴更衣。”
朱弦点点头，走进洗手间先冲洗了一下浴缸，试了水温，然后才往浴缸里注入热水，并帮许半生准备好一应器物，许半生也拿了一套法袍走进洗手间。
简单的冲洗了一下，许半生排尽体内的杂质，任由朱弦一点点仔细的帮他擦拭身体，直到身体之上不再有半颗水珠。
穿上了那件真丝打造的法袍，许半生简直就是仙人之姿，看的朱弦双目发呆，只觉得自己是如此的幸运，才能得到许半生的垂青。
法袍通体纯白，上边用银线绣出一个完整的太极的形状，明明都是洁白的银线，却不知如何勾勒出黑白立体的感觉，那太极之上的阴阳鱼，栩栩如生，黑处极黑，白处雪白，但仔细看去，却又都是银线勾勒，这也算的上是神奇了。
光从这一点，就可以看出这件法袍的神奇之处，朱弦当然知道这也是一件法宝。
许半生赤脚站在了阵法中央，缓缓跌坐下去，双腿盘起，那法袍也仿佛在适应着他的身体，熨帖无比的穿在身上，随着聚灵阵积聚天地灵气的效果，那件法袍也仿佛微微绽放出金色的光辉。
“护法。”许半生轻轻一声，朱弦急忙屏气凝神，再也不敢有丝毫的分心。
也见过许半生炼制其他丹药了，却从未见过许半生如此凝重的姿态，这件法袍也是许半生第一次穿在身上，足见他对这次的炼丹有多么的谨慎。
有了那枚七宝空间戒指之后，许半生的许多法宝都可以直接放在空间戒指之中，心中默念法诀，就可以凭空将那些东西取出。
手一晃，那得自于曾七爷拍卖会上的炼丹炉便出现在许半生的面前。
口中不断念动着口诀，许半生的手指微动，那炼丹炉便轻轻飞在了半空之中。
这只炼丹炉，本是全真七子之中的长生子刘处玄的炼丹鼎炉，刘处玄也是全真七子之中最擅长炼丹之人，这只鼎炉带有刘处玄一生炼丹的沉淀，本身也是一件不可多得的法宝，用其炼丹，绝对是事半功倍。
手掐剑诀，许半生喊了一声疾，那鼎炉的盖子便自行缓缓飞起，许半生的手掌一晃，数味药材便出现在他的掌心之中。
手掌翻动，那些药材便飞入到鼎炉之中，没有半点遗漏。
双手环抱，小小的鼎炉缓缓落在许半生的双手之间，随即滴溜溜的旋转起来，不一会儿便化作一道黑黄色的光芒，其旋转的速度快到平常人的肉眼几不可见的地步。
在朱弦和许半生的眼中，这鼎炉当然还是清晰可见的，朱弦看得清楚，鼎炉已经发出暗红色的光芒，这是许半生用他炼制的三味真火在灼烧着鼎炉。
三味真火，是道家修行者独有的真火，无色透明，不像平常的火焰那样有颜色，若不是能够引起空气的些微波动，根本就察觉不出三味真火的存在。
鼎炉的温度已经极高，许半生却依旧在持续的为鼎炉加温。
在许半生的额头之上，已经隐隐约约出现了几滴汗水，像是许半生这样寒暑不侵的身体，能够让他出汗，可见其已经耗尽自身的精气。
心念一动，空间戒指之中跳出一颗补气丹，许半生口一嘬，那补气丹便进入他的嘴里，瞬间化作涎液流下，被许半生完全吸收，他的精气又恢复到全满的程度。
