"Brother Fool once heard about one or two by chance. Ma Tianxiong nodded, and then a strange look appeared on his face: "Senior Brother Ye seems to be very interested in the best pill, it is said that with your qualifications, as long as you work hard, even if you are the following pill, it is enough to build a foundation." ”

"Huh. Lin Xuan had a smile on his face, but his heart was a pang, he was a little out of shape just now, and he hurriedly said indifferently: "Let the senior brother laugh, the junior brother is just curious, and he is naturally interested in all kinds of anecdotes." ”

"Hmm. Ma Tianxiong didn't doubt it, Lin Xuan's Heavenly Demon Imitation Technique was extremely wonderful, with his current cultivation, unless he was a master of the Ning Dan Period, no one would be able to recognize his true face, Ma Tianxiong continued: "Brother Fool once happened to see an introduction to the best marrow cleansing pill in an ancient book......

This gentleman did not doubt that he had him, anyway, it was not a valuable secret, so he regarded it as a small talk, and told it one by one like Lin Xuan.

It turned out that the grading of the pill circulating in the cultivation realm was wrong.

The lower grade, the middle grade, and the upper grade are indeed divided according to the impurity content, but the legendary best Dan is not only that.

The so-called best pill really has the effect of going against the sky, in addition to the extremely high proportion of essence content in it, there are very few impurities, and it also needs to be quenched twice.

What is secondary quenching?

As we all know, by placing all kinds of heavenly and earthly treasures in the Ding Furnace and refining them by experienced cultivators, you can get the finished elixir.

It's a tempering.

And to get the best pill, you must first prepare the high-grade pill that has been successfully refined, and then supplement it with several other elixirs, and refine it again, which is the so-called alchemy with pills.

Because it is refined twice before and after, it is also called secondary refining.

Just from the process, you can imagine its difficulty, to know the Dao, even if it is a famous sect, with a rich net worth, and at the same time there is a powerful alchemist, it is impossible to refine the Shangpin Dan, the only little inventory in the sect is also passed down from generation to generation, it is said that it is in the case of excellent luck, "accidentally" refined.

Refining the best Dan is to use the Shangpin Dan as raw materials, once it fails, the Shangpin Dan will be scrapped, who is willing to give it, and it will not be so painful that the flesh vomits blood?

However, for Lin Xuan, this is nothing, with his current cultivation, although the success rate of refining the Shangpin Pill is very low, it is barely possible, and it will take some more time at most, which is not a problem.

But what Ma Tianxiong said next really caused him to encounter a problem.

"What, in addition to needing the top grade pill as the main ingredient, when refining it for the second time, how many flavors of heaven and earth spirit grass should be added?"

"Yes. Ma Tianxiong nodded: "According to ancient records, refining the best pill requires silver moon flowers and flowing grass two flavor accessories. ”

The ingredients of the best pill are slightly different from the previous grades of pills, which is also why Lin Xuan has not been able to succeed through the method of purifying and concentrating the essence.

From Ma Tianxiong's mouth, he got the secret about the best pill, but Lin Xuan's heart was not relaxed at all, the top grade pill was easy to do, but this was used as an auxiliary two-flavor spirit grass......

Lin Xuan had seen an introduction to them from the "Hundred Herbs", unlike ginseng and Ganoderma lucidum, silver moon flowers and flowing grass were the real spiritual treasures of heaven and earth, and their number was even rarer than 10,000-year-old ginseng.

Where do you find it?

"In fact, this heaven and earth spirit grass is not without origin. ”

"Senior Brother Zhilu Dao?" Lin Xuan was surprised and delighted, he didn't expect Ma Tianxiong to be five big and three thick, but his knowledge was so rich, he could be called a jack of all trades.

"In the creek and the stream grows there. ”

"Xi Yuejian ah!" Lin Xuan listened, his face was silent, but his expression was a little bitter, for no other reason, this Xi Yuejian is a notorious place where demon beasts grow, and it is extremely dangerous.

If it was just a demon beast's lair, Lin Xuan might not dare to break in, as the saying goes, people die for money, birds die for food, and it is normal to take some risks if you want to obtain the Heaven and Earth Spirit Grass, not to mention that although there are many demon beasts there, most of them are only level 1, and with their current cultivation, they can barely cope with it.

But the current situation is a little different, this Xiyuejian is located in the north of Yanzhou, only a few dozen miles away from the Huoling Gate, which is considered to be the range of their potential, and now the two Xiuzhen Alliances are engaged in a war of attrition, and they are in the camp hostile to them.

It's easy to stay in the sect, but looking at the situation, it is impossible to build a foundation no matter what.

Lin Xuan was in a dilemma, originally he still had a way out, relying on the Heavenly Demon Imitation Technique, taking off the clothes of the Drifting Cloud Valley, and disguised himself as a loose cultivator to go secretly, although this great conflict in the Yanzhou Cultivation Realm made those loose cultivators who did not have any sect and did not belong to any power also suffered miserably, and were injured and killed a lot by mistake, but after all, it was much safer than the disciples of the sect.

But soon, Lin Xuan's wishful thinking was also in vain.

Although it is a war of attrition, there will be no large-scale fights between the two sides and attacks on each other's main altars, but other means are to do everything, don't underestimate these monks who pursue immortal Taoism, usually look like a fairy wind and bones, full of Taoism, but really make insidious tricks, but despicable and shameless, more bloody and cruel than the world.

In addition to hunting each other's lone disciples, they also sent dead soldiers, mixed sects, and assassinated high-level monks, which was a plan to draw salaries from the bottom of the kettle, although most of the dead soldiers who were sent were never returned, but the effect was very obvious.

To know whether a sect is strong or not, the key is still in the high-level monks, the disciples in the spirit period are just cannon fodder, no matter how much they die, they can't hurt the roots, but the high-level monks are different, if there are too many people who die at the hands of assassins, it will make the strength of that sect greatly damaged.

Once the balance of power between the opposing sides is broken, then the next step is no longer a war of attrition, but a never-ending slaughter.

Of course, neither side wanted their sects to fall, and in order to free up the dead assassins sent by the other party, the two alliances each invented an identification spell.

If you put the identification spell into your body, you can see at a glance whether it is your own person or a spy, and you can easily recognize it, so that you are not afraid of the other party's people mixing in.

Phantom Rain: I'm sorry, I've been waiting for everyone for a long time these days, and this week's strong push will restore the update speed, ask for recommendation votes, and my little brother will work hard.
