Du Feng has a kind of treasure, and the four continents of east, west, north and south are very scarce, that is, one yuan of heavy water. In this way, the baby is not sold by the bottle, but by the drop. It only takes a small drop to sell it for a very high price. It just so happens that the price of goods is high on the Nanzhou Continent, and his bottle of one-yuan heavy water is too valuable.

It's a pity to sell it directly for one yuan of heavy water. Du Feng had a better way, which was to add a trace amount of one-yuan heavy water in the process of alchemy, so as to extract the pill. If it was an ordinary alchemist who used one yuan of heavy water to raise the pill from the low grade to the middle grade, it would not make much sense.

But the elixir refined by Du Feng is already the best in itself, and it has to be improved one more time to achieve perfect quality. The so-called perfect quality naturally refers to flawless and no side work. Once the elixir has reached perfect quality, its effect can be comparable to that of the same elixir of the higher order.

For example, the perfect quality of Juyuan Dan, its effect is comparable to Ning Hua Dan. And one of the biggest benefits is that there are no side effects, and you can take a large amount at one time. In the same way, the effect of the perfect quality Ning Hua Dan is comparable to that of the Void Pill. You must know that the Void Pill is an elixir used by Void Sea Realm martial artists to improve their cultivation, and the materials required for refining themselves are very expensive. If you can replace the Void Pill with a perfect grade Ning Hua Dan, I believe that many high-level martial artists are willing to give it a try.

"Are you really going to do that?"

Su Jie was still a little worried, although she had already heard that all the top-grade pills sold in the top-grade curie were refined by Du Feng. But once you add a dollar of heavy water, things get a lot more complicated. First of all, the properties of the medicinal materials will change, and it is easy to make mistakes in the refining process, and it can be said that the failure rate is extremely high.

"That's all there is to it. ”

Du Feng definitely nodded, what he was going to refine today was the most extreme pill within his current ability. This limit refers to the limit after raising the cultivation to the peak of the ninth layer of the Grandmaster Realm with the help of mana transfer, not the limit in the ordinary state.

If you want to make a lot of money, you have to take risks. Risk is always proportional to income. The pill that Du Feng wants to refine this time is the Void Breaking Pill. As the name suggests, the Void Breaking Pill is the pill that the Guiyuan Mirror Martial Artist needs when he breaks through the Void Sea Realm.

To refine this elixir, the minimum requirement for cultivation is a half-step return to the element. Du Feng has only been practicing for more than a year since his reincarnation, and he has gone from the Quenching Body Realm to the Qi Martial Realm to the peak of the ninth layer of the Condensing Martial Realm, which is already a god speed. If you want to achieve a half-step return to the state, it feels like a fantasy.

Half a step back to the yuan, and then the next step is not the return period. Those who break through to the Returning Yuan period before the age of seventy will be able to get a place in the inner city, and if they are less than twenty years old, they want to have a half-step return to the Yuan state, what are you kidding. Frankly, Su Jie didn't believe it much.

She knew that Huang Luosheng could easily break through from the peak of the ninth layer of the Condensing Martial Realm to the Grandmaster Realm, and even some powerful Huang Luosheng could break through all the way to the realm of the third and fourth layers of the Grandmaster Realm. But if you want to achieve half-step return, it is impossible.

"Mana transfer!"

Du Feng didn't care whether she believed it or not, and first used his mana to pass it on. I saw that his cultivation easily broke through from the peak of the ninth layer of the Condensing Martial Realm to the Grandmaster Realm, and then soared all the way up. The first, second, and third floors have reached the fourth floor, which is already the limit that Su Jie can accept.

The fifth layer of the Grandmaster Realm, how is this possible. Before she could get used to it, Du Feng broke through to the fifth layer, followed by the sixth layer, and then the seventh layer...... In one breath, he reached the peak of the ninth layer of the Grandmaster Realm.

"It's too perverted, I'm afraid that Zhan Tian is not his opponent. ”

Su Jie muttered secretly in his heart, wondering how did Brother Xiao know such a madman, no wonder he dared to go against Shangguan Yun single-handedly. Because Xiao Hu did not tell Su Jie Du Feng's specific identity, she only knew that Du Feng had a grudge against Guan Yun, but she didn't know that he was the son of Emperor Dan thousands of years ago.

The peak of the ninth layer of the Grandmaster Realm is very powerful, but it is still a little short of the half-step return to the yuan. The difference in this thread is not in the realm of cultivation, but in the reserves of true yuan. The half-step return to the Yuan period, strictly speaking, is still the cultivation of the peak of the ninth layer of the Grandmaster Realm. However, due to the huge reserves of the true element, the true element was squeezed and became dense, so it was called the half-step return period.

is already so perverted, is there any other way for him to fail? Su Jie stared at Du Feng tightly with a pair of big eyes, wanting to see what other special means he had.

"The god of all beasts listens to my summons, and orders the world not to dare to disobey, and the war beasts are combined. ”

At this moment, the mantra of the war beast sounded, and the figure of Youdao flashed and immediately completed the merger with Du Feng, and Su Jie couldn't see what it was at all. Once the merger was completed, Du Feng's state improved again. Although it was impossible to break through to the realm of the Returning Yuan Period, the True Yuan reserves continued to increase, and after rushing to the cultivation barrier, they were blocked and began to squeeze continuously.

The liquid true element is becoming thicker and thicker, and the half-step return is really a half-step return state. Su Jie opened his small mouth excitedly and couldn't close it, didn't that mean that Du Feng already had the qualifications to become Lan Luosheng. Luo Sheng is different from ordinary martial artists, as long as he meets the standard of Lan Luo Sheng, he can get a place in the inner city.

She was right, in fact, Du Feng's current state. You can break through to the real grandmaster realm at any time, and then borrow the power of mana to transfer the power of merging with the war beast, even if you participate in the Blue Rasheng competition, the ranking will not be too bad. However, before defeating Zhan Tian, he didn't plan to do so for the time being.

Taking advantage of the half-step return state that has been adjusted at the moment, you have to hurry up and refine the Void Breaking Pill. There is no need to waste one yuan of heavy water at all for other grades of elixir. A raging fire had already ignited in the Zijin Dan furnace, but fortunately, the medicinal materials prepared by Old Man Liu Fu were relatively complete, so there was no need to go out to buy them now.

Du Feng distributed the medicinal materials according to the proportion, manipulated a trace of one-yuan heavy water, and began to revolve around the medicinal materials. It's really a trace of water, finer than a hair. The amount is extremely small and transparent, so you can't see it unless you look closely.

Just a little bit of something, after a few more circles, the color of all the medicinal herbs increased by several layers. People who don't know how to do it think that the medicinal herbs are broken. In fact, Du Feng removed the impurities in the medicinal materials through one yuan heavy water, leaving only the essence. And when these essences are compressed again, the density becomes very large.

A batch of medicinal herbs that were originally good looked like a little remnant of the medicine residue at the moment. However, Su Jie clearly felt the rich medicinal power from these "medicine residues". Even if it is not refined into an elixir, the price of medicinal materials that have been purified to this extent will have to rise several times.

What kind of person is he, the alchemy technique is so terrifying, even the top alchemist in Ishihara City can't do it. Su Jie stared at Du Feng's side face and observed carefully, but he couldn't see any clues.
