The path of cultivation is difficult to reach the blue sky, and there is no room for the slightest trick. It's difficult, it's difficult, it's very difficult, if you want to become a powerful person on the Nine Heavens Continent, you must meet three conditions, these are the three most basic conditions, the first, first of all, you must have a good heavenly soul, the second is that you must have a lot of pills to support you, and the third is to rely on diligence.

Of these three conditions, the first is the most important, the second is second, and the third is again.

The reuse of the pill is actually similar to that of the Heavenly Soul. Not everyone has a good Heavenly Soul, many Tongtian characters on the Nine Heavens Continent, their descendants and Heavenly Souls, are not very good, it is these Tongtian characters who provide pills at no cost, and their children and grandchildren have all become. The supreme master of the Nine Heavens Continent.

Not every martial artist has a good heavenly soul, and without a good heavenly soul, the vast majority of martial artists can only rely on pills and diligence, and these two items are supplemented.

Everyone can have diligence, but this elixir is not something that ordinary people can have. And those big people used extremely high-grade pills to raise their descendants who were not very good in their heavenly souls to the supreme level of the heavenly souls.

The importance of the elixir can be imagined.

This is also the reason why, in the entire Nine Heavens Continent, the holy land of the Pill Medicine Master, Medicine Valley, has always been at the top of the Nine Heavens Continent, and all the super forces dare not offend the Medicine Valley.

However, if there is an endless supply of pills, this is really not the treatment that a poor martial artist can enjoy. Even if some people are extremely talented and have a demonic understanding, when they first cultivate, there is no supply of good pills. After a lot of years, because the foundation was not solid, he died in the end, so it became a big regret on the Nine Heavens Continent.

This is why the vast majority of Heavenly Soul Scholars want to join the super forces, because these super sects have deep pockets, and they have a lot of good pills, which can provide the best resources for the martial artists.

It is precisely because of the supply of the best elixirs that among these super sects, there will be endless masters. Of course, there are many reasons why a force is strong.

However, it is undeniable that there are two most important ones: one is the strictness with which they select their disciples.

The second is that the elixirs provided by these big sects, and the grade is higher than that of the small sects.

These super sects have better talents than others, better pills than others, and better exercises than others, so that they can create batches and batches of peerless masters.

On the Nine Heavens Continent, the alchemist can be regarded as an extremely noble existence, comparable to the mysterious array mage. Alchemists are very sought-after on the Nine Heavens Continent, even a little more sought-after than array mages, why is this so?

Because alchemy is an extremely cumbersome project, experience is very important, only by immersing yourself in this industry, will there be progress, otherwise, it is just wasting the years, a good alchemist, that is gray hair, I don't know how old the old man is.

And on the Nine Heavens Continent, a good pill is more precious than a good alchemist, why is this happening? Because even if he is an extremely powerful alchemist, it is impossible for him to refine every furnace of pills, which can guarantee that the refining of this furnace of pills can be 100% successful.

Even Wei Xiangxian, the most noble Dan King in the Nine Heavens Continent, did not dare to guarantee that each of his furnaces of pills could be successfully refined.

That's the Dan King, among the alchemists of the Nine Heavens Continent, the top existence like the ivory tower - the Dan King, even the Dan King can't be guaranteed, and the ordinary alchemists can't guarantee it.

Among the ten furnaces of their refining pills, they can succeed in five or six furnaces of pills, which is considered very good.

If the pill is refined, it is worthless, because the pill that has been refined and wasted has too many impurities, and if you take it indiscriminately, you may hang up and die, not necessarily. These waste pills, only those who are really poor to death, and there are no pills to take, will take the risk of trying.

There will be a big problem with the waste pill, but the chance is very small, a hundred people who use the waste pill may die, only one.

But one percent is also one percent, and who dares to guarantee that he will not be the most unlucky one among the 100 people.

Therefore, unless it is absolutely necessary, the warriors will not use the waste pill to improve the true yuan, after all, the effect of this waste pill is pitiful, and there is a danger to life, who would be so stupid, don't eat the waste pill.

Only, in the case of a last resort, will be used, Ye Yi did not plan to use the waste pill at all, when the school issued him the waste pill, he couldn't cry or laugh, just took it to study, what the waste pill is, as a result, I found that the tree of the world, can be upgraded with the waste pill, this special ability, this is something that even the old man doesn't know.

It's no wonder, after all, Tian Lao has never obtained the World Tree, and he is not a god, so it is normal not to know about this matter.

From the beginning of heaven and earth, the beginning of Hongmeng, to the present, it has gone through Hongmeng, Chaos, primeval, ancient, and medieval eras, and now, with the Heavenly Soul Warrior, there are more and more.

The spiritual grass resources between heaven and earth are becoming more and more scarce, and even, many spiritual grasses have become extinct, and spiritual grass is needed to refine the elixir.

And this spirit grass has become so rare, coupled with the difficulty of refining the pill, the success rate is not strong, which makes the good pill very precious in today's Nine Heavens Continent.

Most sects, even if they are in charge, are using inferior pills, like the instructors of the War Academy, most of them use low-grade pills, and when they are most luxurious, they also use one or two medium-grade pills, and when they are about to break through, they grit their teeth and use them.

High-level elixirs, that is, above the sixth order, have, only exist in legends, super-rank, elixirs above the tenth order, uh, the disciples of the War Academy don't even dare to think about it.

Especially for the lowest level martial artist like Ye Yi, the top-grade elixir really only existed in legends, and he thought that maybe only that kind of super sect would have these high-grade elixirs.

The War College is very large, among which there are five hundred and eight students of the fifth order of the Great Heavenly Master, all of whom are famous and well-known figures, and each of them can get ten pills every month, and the first-order lower grade pills.

That is to say, the pills they need, a total of five thousand and eighty, and the number of waste pills produced is also this number, and the alchemists take the waste pills and throw them away directly, after all, this kind of thing is not much good for martial artists, but the harm is very huge, except for those low-level garbage students, I am afraid that no martial artist will take it.

Ye Yi thought in his heart: "If you want to bring all these waste pills over, then you will really get rich, and he will soon become the richest person in the Nine Heavens Continent, but the wealth is not exposed, this matter has to be considered in the long run, well, I want to find Tian Lao, the alchemist, to analyze it." ”

"Now I want to make sure, is the power of this World Tree really able to upgrade the elixir?"

Ye Yi felt that what he had to do now was to find out, could the energy generated on the World Tree really help him purify the pill?

Thinking so, Ye Yi took the porcelain vase from his arms again. Pour out the first-order elixir - Chong Ling Dan, of course, this is also a waste pill, this Chong Ling Pill is white, this grain has no fragrance, not to mention, but has a smell, and the dog's stool has a fight.

Ye Yi sat down cross-legged again, forcibly enduring the peculiar smell emitted by the elixir, and transformed the power of the World Tree in his body.

With Ye Yi's closed eyes, his entire body burst out of white light, and then, a substantial white light flew out of his pores and flowed to his body, transforming his bones and seven meridians and eight veins.

Ye Yi was holding the pill in his hand, this time, the pill in his hand was taken care of by Bai Guang again, this time, after running the power of the world in his body, it was finished.

Ye Yi opened his eyes, and he found that when Bai Guang transformed the pill this time, a ball of black powder fell on the ground, and this black powder exuded a very stinky smell.
