許半生又笑道：“你這小畜生，說話總是不實不盡的，你口口聲聲壞道士，若不是我師父傳你功法，使你抗拒天劫，你現在早就與這個世界無關了。”
赤兔聞言，略有些羞澀的低下了頭，兩隻小前爪擋在眼前，似乎很不好意思的樣子。
“暫時留在家裡吧，目前我也幫不了你什麼，不過這總是你的一個機緣。或許有人可以幫得了你，又或許過些日子我突破到意之境，倒是有可能助你一臂之力。”許半生將赤兔放在地上，赤兔知道這是許半生答應幫它，早也就知道把握不大，它現在反正也沒什麼選擇可言，能得到許半生一句承諾，心裡也自是滿足了。
“放心吧，小赤兔，主人至少可以幫你安然渡過天劫。”朱弦對赤兔總是有些心懷歉意，出言安慰。
赤兔點了點頭，眨巴眨巴藍汪汪的大眼睛，頭頂那對長耳朵向後耷拉下去。
許半生看在眼裡，也是默默的點了點頭，朱弦本是個妖靈，除了對自己之外，對其他人其實都沒有什麼感情可言。如今她懂得憐惜赤兔，倒也是一場不錯的緣法。有了愛憐之心，才能夠真正算是一個人類，否則，始終還是脫不了身上的妖氣。
看起來，這趟讓朱弦去日本真的是去對了，至少讓朱弦有了仁心，假以時日與其道心結合，她纔算是真正的修成正果。
“先且呆在家裡吧，朱弦，你隨我上樓，替我護法，我要煉製丹藥。”許半生走向大門，朱弦趕忙跑過去幫他開了門，又有些不放心的回頭看看赤兔，赤兔很懂事的點點頭，表示自己會老老實實的呆着。
出了門，許半生又回頭說道：“小畜生，這裡終究不比你常呆的地方，稍稍做些修行，對你只有好處。”
赤兔知道這是許半生在指點自己，它離開霧島山的火山之後，的確是各種不適，若非朱弦一路上一直用自己的精氣化作火炎，它怕是早就有些受不了。修行當然可以幫助它適應這裡的環境，可它總擔心修行會使得它遭遇天劫，到時候只怕是得不償失。所以便一直忍耐着各種不適，現在許半生告訴它可以適當的修行，它纔敢吸收天地靈氣。
上了樓，朱弦看到樓上原本的聚靈陣之中，又被許半生重新佈置過了，想來是爲了煉製丹藥做的準備。
許半生說道：“放水，我要沐浴更衣。”
朱弦點點頭，走進洗手間先沖洗了一下浴缸，試了水溫，然後才往浴缸裡注入熱水，並幫許半生準備好一應器物，許半生也拿了一套法袍走進洗手間。
簡單的沖洗了一下，許半生排盡體內的雜質，任由朱弦一點點仔細的幫他擦拭身體，直到身體之上不再有半顆水珠。
穿上了那件真絲打造的法袍，許半生簡直就是仙人之姿，看的朱弦雙目發呆，只覺得自己是如此的幸運，才能得到許半生的垂青。
法袍通體純白，上邊用銀線繡出一個完整的太極的形狀，明明都是潔白的銀線，卻不知如何勾勒出黑白立體的感覺，那太極之上的陰陽魚，栩栩如生，黑處極黑，白處雪白，但仔細看去，卻又都是銀線勾勒，這也算的上是神奇了。
光從這一點，就可以看出這件法袍的神奇之處，朱弦當然知道這也是一件法寶。
許半生赤腳站在了陣法中央，緩緩跌坐下去，雙腿盤起，那法袍也彷彿在適應着他的身體，熨帖無比的穿在身上，隨着聚靈陣積聚天地靈氣的效果，那件法袍也彷彿微微綻放出金色的光輝。
“護法。”許半生輕輕一聲，朱弦急忙屏氣凝神，再也不敢有絲毫的分心。
也見過許半生煉製其他丹藥了，卻從未見過許半生如此凝重的姿態，這件法袍也是許半生第一次穿在身上，足見他對這次的煉丹有多麼的謹慎。
有了那枚七寶空間戒指之後，許半生的許多法寶都可以直接放在空間戒指之中，心中默唸法訣，就可以憑空將那些東西取出。
手一晃，那得自於曾七爺拍賣會上的煉丹爐便出現在許半生的面前。
口中不斷念動着口訣，許半生的手指微動，那煉丹爐便輕輕飛在了半空之中。
這隻煉丹爐，本是全真七子之中的長生子劉處玄的煉丹鼎爐，劉處玄也是全真七子之中最擅長煉丹之人，這隻鼎爐帶有劉處玄一生煉丹的沉澱，本身也是一件不可多得的法寶，用其煉丹，絕對是事半功倍。
手掐劍訣，許半生喊了一聲疾，那鼎爐的蓋子便自行緩緩飛起，許半生的手掌一晃，數味藥材便出現在他的掌心之中。
手掌翻動，那些藥材便飛入到鼎爐之中，沒有半點遺漏。
雙手環抱，小小的鼎爐緩緩落在許半生的雙手之間，隨即滴溜溜的旋轉起來，不一會兒便化作一道黑黃色的光芒，其旋轉的速度快到平常人的肉眼幾不可見的地步。
在朱弦和許半生的眼中，這鼎爐當然還是清晰可見的，朱弦看得清楚，鼎爐已經發出暗紅色的光芒，這是許半生用他煉製的三味真火在灼燒着鼎爐。
三味真火，是道家修行者獨有的真火，無色透明，不像平常的火焰那樣有顏色，若不是能夠引起空氣的些微波動，根本就察覺不出三味真火的存在。
鼎爐的溫度已經極高，許半生卻依舊在持續的爲鼎爐加溫。
在許半生的額頭之上，已經隱隱約約出現了幾滴汗水，像是許半生這樣寒暑不侵的身體，能夠讓他出汗，可見其已經耗盡自身的精氣。
心念一動，空間戒指之中跳出一顆補氣丹，許半生口一嘬，那補氣丹便進入他的嘴裡，瞬間化作涎液流下，被許半生完全吸收，他的精氣又恢復到全滿的程度。
