nà yàng bù guò shì yōng rén zì rǎo ér yǐ 。
那样不过是庸人自扰而已。
That was merely a case of worrying over nothing.
yī qiè shùn qí zì rán jiù hǎo 。
一切顺其自然就好。
Let everything take its natural course.
xīn zhōng rú cǐ xiǎng zhe ， lín xuān huí dào le dòng fǔ 。
心中如此想着，林轩回到了洞府。
With this thought, Lin Xuan returned to his cave dwelling. There were still many things he needed to do now.
rú jīn tā hái yǒu xǔ duō shì qíng yào zuò 。
如今他还有许多事情要做。
As for the avatar side, since it was already well-prepared, there was no need to worry about anything extra.
zhì yú huà shēn nà biān ， jì rán yǐ jīng zhǔn bèi chōng zú ， nà yě jiù méi yǒu bì yào ， zài qù é wài de dān xīn shén me 。
至于化身那边，既然已经准备充足，那也就没有必要，再去额外的担心什么。
Lin Xuan had confidence in his own strength. Even if something unexpected happened, the avatar would be able to handle it.
duì yú zì jǐ de shí lì ， lín xuān hái shì yǒu xìn xīn de ， jiù suàn zhēn yǒu shén me biàn gù ， huà shēn yě zú yǐ yìng fù 。
对于自己的实力，林轩还是有信心的，就算真有什么变故，化身也足以应付。
He decided to first see what his senior brothers and sisters had brought him.
qiě xiān kàn kàn shī xiōng shī jiě ， gěi zì jǐ sòng lái le shén me zài shuō 。
且先看看师兄师姐，给自己送来了什么再说。
With that thought, Lin Xuan flicked his sleeve.
xīn zhōng rú cǐ xiǎng zhe ， lín xuān xiù páo yī fú 。
心中如此想着，林轩袖袍一拂。
A burst of spiritual light flashed before a pale silver box appeared before him. It was not more than half a foot long and emitted a faint fragrance.
líng guāng kuáng shǎn ， jǐn jiē zhe ， yī kǒu dàn yín sè de xiāng zi jiù fú xiàn yú yǎn qián 。
灵光狂闪，紧接着，一口淡银色的箱子就浮现于眼前。
This was the one sent by those three junior disciples just now.
zhǎng bù guò bàn chǐ ， sàn fà zhe dàn dàn de xiāng qì 。
长不过半尺，散发着淡淡的香气。
"Quickly!"
zhèng shì gāng gāng nà sān wèi shī zhí wèi zì jǐ sòng lái dì 。
正是刚刚那三位师侄为自己送来地。
Lin Xuan raised his right hand and pointed it at the front.
“ jí ！”
“疾！”
With such an unremarkable action, a "thud" sounded in his ears as the restrictions on the box were lifted. The lid opened to reveal several black stones inside.
lín xuān yòu shǒu tái qǐ ， xiàng zhe qián fāng diǎn qù 。
林轩右手抬起，像着前方点去。
At first glance, they did not seem impressive, but to Lin Xuan, a high-ranking cultivator, their extraordinary nature was evident.
jiù zhè me yí gè bù qǐ yǎn de dòng zuò 。
就这么一个不起眼的动作。
There seemed to be some extremely powerful spiritual energy left on them, no... it wasn't spiritual energy; it should be something even more advanced. However, these were mixed with strange impurities, turning what could have been precious spirit stones into waste. Even if the grade was off the charts, they would still be unusable.
“ pā dā ” yī shēng chuán rù ěr duǒ ， nà xiāng zi biǎo miàn de jìn zhì yǐ bèi jiě chú ， suí hòu nà xiāng gài dǎ kāi ， jǐ kuài hēi hū hū de shí tou yìng rù yǎn lián 。
“啪嗒”一声传入耳朵，那箱子表面的禁制已被解除，随后那箱盖打开，几块黑乎乎的石头映入眼帘。
Indeed, the pale silver box contained nothing but waste spirit stones.
zhà yī kàn bìng bù qǐ yǎn ， rán ér luò zài lín xuān zhè děng gāo jiē xiū shì de yǎn zhōng ， què kě yǐ kàn chū tā de bù fán 。
乍一看并不起眼，然而落在林轩这等高阶修士的眼中，却可以看出它的不凡。
Lin Xuan roughly counted them and found there were twelve in total.
shàng miàn sì hū hái cán liú zhe yī xiē jí wéi liǎo bù qǐ de líng qì ， bù …… bú shì líng qì ， yīng gāi shì gèng gāo jí de dōng xī ， rán ér què yǔ yī xiē gèng jiā gǔ guài de zá zhì hùn zài yì qǐ ， rú cǐ yī lái ， hǎo hǎo yī kuài xiān shí yě jiù biàn chéng le fèi wù ， jí biàn pǐn jiē zài lí pǔ ， yě shì gēn běn jiù méi yǒu bàn fǎ shǐ yòng 。
上面似乎还残留着一些极为了不起的灵气，不……不是灵气，应该是更高级的东西，然而却与一些更加古怪的杂质混在一起，如此一来，好好一块仙石也就便成了废物，即便品阶再离谱，也是根本就没有办法使用。
Upon realizing this, a trace of excitement flashed across his eyes.
méi cuò ， yǎn qián zhè dàn yín sè xiāng zi zhōng zhuāng zhe de ， jiù shì fèi pǐn xiān shí 。
没错，眼前这淡银色箱子中装着的，就是废品仙石。
Spirit stones... in the Spirit Realm, these truly were something remarkable. Even for old monsters at the Tribulation Transcending stage, they were heaven-defying treasures, almost unattainable.
lín xuān cū lüè yī shù ， gòng shí èr kuài zhī duō 。
林轩粗略一数，共十二块之多。
He casually picked one out, and it could easily trigger bloodshed. The conflict between the three sects and Cloud Concealing Sect was a good example.
chá jué dào zhè yì diǎn ， lín xuān yǎn móu shēn chù ， bù yóu de shǎn guò yì diǎn xīng fèn zhī sè 。
察觉到这一点，林轩眼眸深处，不由得闪过一点兴奋之色。
Originally, he had already obtained a finished spirit stone.
xiān shí xiān shí ， zài líng jiè ， nà kě dàng zhēn liǎo bù qǐ 。 jí biàn duì dù jié qī lǎo guài wù 。 yě shì nì tiān zhī wù ， kān chēng kě yù ér bù kě qiú de 。
仙石仙石，在灵界，那可当真了不起。即便对渡劫期老怪物。也是逆天之物，堪称可遇而不可求的。
Now with twelve more waste stones, if he could refine them...
suí biàn ná chū yī kuài ， jiù zú yǐ yǐn fā xīng fēng xuè yǔ 。 xiān qián sān pài lián méng yǔ yún yǐn zōng de fēn zhēng ， jiù hěn hǎo de zhèng míng 。
随便拿出一块，就足以引发腥风血雨。先前三派联盟与云隐宗的纷争，就很好的证明。
Lin Xuan couldn't help but feel excited at this thought.
zì jǐ yuán běn yǐ dé dào yī kuài chéng pǐn xiān shí le 。
自己原本已得到一块成品仙石了。
Spirit stones were indeed extraordinary, but refining these wastes wasn't easy. He had only just entered the Immortal Path and possessed the Blue Star Sea. His achievements were partly due to this treasure, so he was already quite familiar with how to use it.
rú jīn yōng yǒu de fèi liào yòu yǒu le shí èr kuài zhī duō ， rú guǒ néng jiāng tā men tí chún chū ……
如今拥有的废料又有了十二块之多，如果能将它们提纯出……
Refinement sounded wonderful, but it wasn't that simple.
xīn zhōng rú cǐ xiǎng zhe 。 nǐ ràng lín xuān zěn me bù jī dòng ne ？
心中如此想着。你让林轩怎么不激动呢？
Firstly, there was only one chance for refinement; if it failed, impurities would mutate and become even more entangled, leaving no further opportunity.
bù guò gāo xìng yī huì er hòu ， lín xuān yòu chóng xīn lěng jìng le xià lái ， xiān shí gù rán bù fán ， dàn zhè fèi liào ， què bìng bú shì nà me róng yì tí chún chū lái 。
不过高兴一会儿后，林轩又重新冷静了下来，仙石固然不凡，但这废料，却并不是那么容易提纯出来。
Secondly, many things could be refined, but the difficulty varied. As the grade increased, so did the difficulty.
lín xuān jī hū shì tà rù xiān dào méi duō jiǔ ， jiù yōng yǒu le lán sè xīng hǎi ， yǒu rú jīn de chéng jiù ， yí dìng chéng dù ， yě kě yǐ shuō 。 shì tuō cǐ bǎo de fú ， duì yú rú hé yùn yòng cǐ wù ， zì rán shì zǎo jiù jià qīng jiù shú 。
林轩几乎是踏入仙道没多久，就拥有了蓝色星海，有如今的成就，一定程度，也可以说。是托此宝的福，对于如何运用此物，自然是早就驾轻就熟。
Fortunately, the Blue Star Sea wasn't static.
tí chún tīng zhe měi miào wú bǐ 。 dàn yě bìng bú shì nà me róng yì 。
提纯听着美妙无比。但也并不是那么容易。
As Lin Xuan's strength grew, the volume of the star sea expanded, and its refining capabilities gradually enhanced.
shǒu xiān 。 tí chún de jī huì zhǐ yǒu yī cì ， ruò shì shī bài 。 zá zhì jiāng fā shēng biàn yì ， bìng qiě gèng jiā jǐn mì de jiū chán zài yì qǐ ， cóng ér ， zài yě méi yǒu tí chún jī huì dì 。
首先。提纯的机会只有一次，若是失败。杂质将发生变异，并且更加紧密的纠缠在一起，从而，再也没有提纯机会地。
However, he still felt somewhat unprepared. Fortunately, part of the light points in the Blue Star Sea had turned silver.
qí cì ， néng gòu tí chún de dōng xī yǒu hěn duō ， dàn bù tóng de dōng xī ， tí chún yě shì yǒu bù tóng de nán dù ， bìng qiě suí zhe pǐn jí de tí shēng ， nà nán dù yě shì zhú jiàn shēng gāo dì 。
其次，能够提纯的东西有很多，但不同的东西，提纯也是有不同的难度，并且随着品级的提升，那难度也是逐渐升高地。
The refinement ability of these silver light points was much greater than ordinary blue ones.
xìng hǎo ， lán sè xīng hǎi yě bú shì yī chéng bù biàn 。
幸好，蓝色星海也不是一成不变。
But this challenge was no small matter; spirit stones were divine treasures. Could the silver light points truly refine them?
suí zhe lín xuān shí lì de zēng zhǎng ， xīng hǎi de tǐ jī ， yě yì zhí zài kuò zhǎn ， bìng qiě tí chún de néng lì yě zài zhú cì zēng qiáng 。
随着林轩实力的增长，星海的体积，也一直在扩展，并且提纯的能力也在逐次增强。
Lin Xuan wasn't sure and didn't have much confidence, but he believed that trying was necessary to know the outcome.
dàn lín xuān yī jiù yǒu lì bù cóng xīn zhī gǎn ， xìng hǎo lán sè xīng hǎi yòu fā shēng le yì biàn ， qí zhōng yī bù fèn guāng diǎn ， huà wèi le yín sè 。
但林轩依旧有力不从心之感，幸好蓝色星海又发生了异变，其中一部分光点，化为了银色。
After all, he wouldn't know if he could do it unless he tried himself.
ér zhè zhǒng yín sè guāng diǎn de tí chún néng lì ， kě shì bǐ pǔ tōng de lán sè guāng diǎn shèng guò xǔ duō 。
而这种银色光点的提纯能力，可是比普通的蓝色光点胜过许多。
Lin Xuan certainly wasn't lacking in courage.
rán ér ， zhè yī cì de tiǎo zhàn fēi tóng xiǎo kě ， xiān shí ， nà kě shì xiān jiā zhī wù ， yín sè guāng diǎn suī rán liǎo de ， dàn zhēn néng jiāng qí tí chún chū me ？
然而，这一次的挑战非同小可，仙石，那可是仙家之物，银色光点虽然了得，但真能将其提纯出么？
With twelve spirit stones as waste materials, this cost was more than enough for him to take a risk.
lín xuān bù xiǎo de ， xīn zhōng kě yǐ shuō ， bìng méi yǒu tài dà de bǎ wò 。
林轩不晓得，心中可以说，并没有太大的把握。
This was the saying: the greater the risk, the greater the reward. Lin Xuan had that kind of awareness.
dàn fán shì zǒng yào cháng shì yī xià cái zhī dào jié guǒ ， zì jǐ ruò bù qīn shǒu shì shàng yī shì ， yòu zěn me huì zhī dào zì jǐ jiū jìng bàn bù bàn dé dào ne ？
但凡事总要尝试一下才知道结果，自己若不亲手试上一试，又怎么会知道自己究竟办不办得到呢？
Clearing his mind, Lin Xuan first calmed down his somewhat agitated emotions. Although he had been refining for years and found it quite familiar, he still couldn't claim a 100% success rate. Especially this time, dealing with spirit stones, even though he was well-versed in various treasures, this grade of treasure was something new to him. Thus, he remained cautious.
lín xuān kěn dìng shì bù quē fá yǒng qì de 。
林轩肯定是不缺乏勇气的。
With a few breaths, Lin Xuan sank into his divine sense and used Inner Vision. Everything in the dantian remained unchanged; the Blue Star Sea continued its slow rotation deep within, calm and undisturbed. The difference now was that the innermost layer of the star sea had an overwhelmingly large number of silver light points compared to before, almost taking up one-fifth of the entire volume.
fǎn zhèng xiān shí fèi liào de shù liàng ， zú zú yǒu shí èr kuài zhī duō ， zhè běn qián yě shì gòu chōng zú ， kě yǐ ràng zì jǐ mào yī mào xiǎn le 。
反正仙石废料的数量，足足有十二块之多，这本钱也是够充足，可以让自己冒一冒险了。
Back then, when he first obtained this treasure, the star sea's size had expanded by thousands of times. Hence, even with only a fifth of it being silver light points, that was already quite impressive.
zhè yě suàn shì yǒu shě cái yǒu dé ， gǎn mào duō dà de fēng xiǎn ， xiāng yìng de ， cái huì yǒu duō dà shōu huò 。
这也算是有舍才有得，敢冒多大的风险，相应的，才会有多大收获。
Clearly, these were the main force for refinement.
zhè diǎn jué wù lín xuān hái shì yǒu de 。
这点觉悟林轩还是有的。
After all, refining higher-grade materials was more difficult. Even facing spirit realm beings, the blue light points were showing signs of strain.
nǎo hǎi zhōng niàn tou zhuǎn guò ， jiē xià lái ， jiù méi yǒu shén me hǎo yóu yù le 。
脑海中念头转过，接下来，就没有什么好犹豫了。
Spirit stones?
shēn shēn hū xī ， lín xuān xiān jiāng lüè yǒu xiē jī dòng de xīn qíng píng fù xià qù ， suī rán zhè me duō nián guò qù ， tí chún duì tā lái shuō ， yǐ shì jià qīng jiù shú ， rán ér yī jiù bù gǎn shuō yǒu bǎi fēn zhī bǎi de chéng gōng lǜ ， yóu qí zhè yī cì yào tí chún de ， nǎi shì xiān shí ， lín xuān suī jiàn shí guǎng bó ， dàn zhè zhǒng děng jiē de bǎo wù ， bì jìng hái shì dì yī cì jiē chù ， yú qíng yú lǐ ， dōu bù gǎn yǒu fēn háo dà yì ， jiāng shí èr fēn jīng shén dǎ dié qǐ 。
深深呼吸，林轩先将略有些激动的心情平复下去，虽然这么多年过去，提纯对他来说，已是驾轻就熟，然而依旧不敢说有百分之百的成功率，尤其这一次要提纯的，乃是仙石，林轩虽见识广博，但这种等阶的宝物，毕竟还是第一次接触，于情于理，都不敢有分毫大意，将十二分精神打叠起。
Lin Xuan suspected that the blue light points had no use.
bì jìng ， jí biàn shì fèi pǐn xiān shí ， zài líng jiè lái shuō ， nà yě shì kuàng shì nán xún zhī wù ， ruò shì yīn wèi yī shí dà yì ， ràng tí chún de chéng gōng lǜ guò dī ， zì jǐ hái bù xīn téng sǐ 。
毕竟，即便是废品仙石，在灵界来说，那也是旷世难寻之物，若是因为一时大意，让提纯的成功率过低，自己还不心疼死。
Of course, this was just his guess; he needed to try and see before making a conclusion.
xīn zhōng huái zhe jǐ fēn tǎn tè ， lín xuān chén rù shén shí ， shī zhǎn nèi shì zhī shù ， dān tián zhōng yī qiè rú gù ， lán sè xīng hǎi yī jiù zài dān tián shēn chù huǎn huǎn xuán zhuǎn zhe ， píng jìng wú bō ， ruò shuō yǔ yǐ qián de bù tóng ， jiù shì lán sè xīng hǎi de zuì lǐ céng ， yín sè guāng diǎn de shù liàng yǔ yǐ qián xiāng bǐ ， yǐ shì bù kě tóng rì ér yǔ ， jī hū yǐ dá dào le zhěng gè xīng hǎi tǐ jī de wǔ fēn zhī yī 。
心中怀着几分忐忑，林轩沉入神识，施展内视之术，丹田中一切如故，蓝色星海依旧在丹田深处缓缓旋转着，平静无波，若说与以前的不同，就是蓝色星海的最里层，银色光点的数量与以前相比，已是不可同日而语，几乎已达到了整个星海体积的五分之一。
With these thoughts in mind, Lin Xuan's actions didn't stop. He took deep breaths and began using divine consciousness to mobilize the light points within his body.
yào xiǎo de ， yǔ chū dé cǐ bǎo shí bù tóng 。
要晓得，与初得此宝时不同。
This refinement was different from previous ones, so Lin Xuan had to be meticulous about the sequence of light point mobilization.
zhěng gè xīng hǎi de tǐ jī ， zǎo yǐ kuò zhǎn le qiān bǎi bèi bù zhǐ ， gù ér yín sè guāng diǎn suī rán zhǐ zhàn dào wǔ fēn zhī yī ， dàn nà yǐ shì jí wéi kě guān dì 。
整个星海的体积，早已扩展了千百倍不止，故而银色光点虽然只占到五分之一，但那已是极为可观地。
The first were pure blue light points densely packed together, almost crowded without any gaps.
xiǎn rán ， zhè xiē guāng diǎn cái shì tí chún de zhǔ lì 。
显然，这些光点才是提纯的主力。
His body's resilience compared to a demon race and the capacity of his meridians were already beyond comprehension. Otherwise, another cultivator at the same stage with such a number of blue light points flowing through their meridians would have exploded long ago.
bì jìng ， yuè shì gāo jiē de cái liào bǎo wù ， tí chún yuè nán ， jiù suàn miàn duì fēn shén jí bié de dōng xī ， lán sè guāng diǎn yǐ jiàn jiàn yǒu le lì bù cóng xīn zhī gǎn 。
毕竟，越是高阶的材料宝物，提纯越难，就算面对分神级别的东西，蓝色光点已渐渐有了力不从心之感。
But for Lin Xuan, it was nothing.
xiān shí ？
仙石？
No discomfort showed on his face.
lín xuān huái yí ， lán sè guāng diǎn gēn běn jiù méi yǒu yòng chǔ 。
林轩怀疑，蓝色光点根本就没有用处。
Following the pure blue light points, there were two different colored lights flashing—blue and silver. They intertwined in a 2:1 ratio.
dāng rán ， zhè yě jǐn jǐn shì zì jǐ de chuǎi mó ， jù tǐ shì bú shì ， hái yào zuì zhōng zuò yī fān cháng shì ， suí hòu cái gǎn xià jié lùn de 。
当然，这也仅仅是自己的揣摩，具体是不是，还要最终做一番尝试，随后才敢下结论的。
After all, the number of silver light points was still insufficient; mixing them with blue ones could complement each other. This experience came from years of Lin Xuan's exploration, and it was undoubtedly useful.
That was merely a case of worrying over nothing.
Let everything take its natural course.
With this thought, Lin Xuan returned to his cave dwelling. There were still many things he needed to do now.
As for the avatar side, since it was already well-prepared, there was no need to worry about anything extra.
