At this moment, Wu Ma's face looked shocked and incredible.

One drop can be kept from being affected by the yin energy and scorching energy of the large refining field for ten days. This effect is terrible.

You know, before that, although there were some potions that could resolve the pain of water and fire in the large refining field, their effect was far less than that of this insulating potion, and the difference was too big.

"You are serious about this, sure you are not joking?"

He couldn't help asking, still a little disbelief.

It’s really too much to do with this matter. If Qin Feng’s potion really has this level of effect, the pattern of Fengdu City will change! Qin Feng smiled faintly and said, “It’s true, there is absolutely no problem!”

"I have tried it in various ways, and there will be no problem. This insulating potion can indeed dissolve the yin energy and scorching energy in the large refining field, and there will be no leakage, and it can be completely resolved!"

"Even if it gradually begins to fade away the remaining medicinal properties, it can be completely able to withstand another ten days. In other words, this drop of insulating potion can guarantee that a dead spirit will last for at most twenty days in Fengdu City!"

Wu Ma only felt terrified all over and his brain was blank. The effect was really amazing.

Twenty days, this concept is scary just thinking about it.

There are two reasons why the stones of the Great Refining Field are refining slowly.

First, it is because it is really too difficult to refine! Second, it is because the endless pain brought by the large refining place has indeed seriously interfered with the process of refining the stones of life! Just enduring that pain has consumed too much of the energy of the undead. If there is no such interference, the progress will be increased to a very terrifying level and the efficiency will be greatly improved.

At present, Qin Feng actually took out this potion that can completely resolve this pain. For countless undead, it is undoubtedly a long time to experience a rain of drought! If this insulating potion can be mass-produced, the pattern of Fengdu City can now begin to change! "This potion is rare in the city, but most of the potions used to resolve the pain in the big refining field have basically some side effects. I wonder what side effects this insulating potion have?"

Wuma couldn't help asking.

He was not fascinated by the insulating potion. Although the insulating potion is indeed powerful, it would be useless if there are any serious side effects.

“No side effects!”

Qin Feng explained.

Wu Ma was stunned when he heard this, but he was a little disbelief: "This is not a joke. If there are any serious side effects, then no matter how good the effect is, it may be difficult to be truly used!"

"This kind of similar potion has appeared in Fengdu City in the past, and the effect is slightly worse than your insulating potion, but its side effects are so high that it is terrifying that it can only cause the spirit to be broken!"

"I guarantee my life, and there are absolutely no side effects. This is also the result I got after trying countless times, and there will be no mistakes!"

Qin Feng said in a deep voice, his expression very serious.

Wu Ma looked at Qin Feng's serious expression and felt very happy. If there were no side effects, the effect of this insulating potion was indeed amazing. It was basically the number one in the city.

However, there is another question, that is, the yield of this insulating potion. Although the efficacy is good, if there is no energy production, it will not affect the overall situation.

"I wonder if I can tell me what this insulating potion is developed. If it is mass-produced, how effective is it?"

He asked.

Qin Feng smiled and said, "There are not many things to be used to refine insulating medicine. Apart from some auxiliary herbs, there are only two main things, the liquid accumulation substance in the Heihe River water, which is also the most important substance to resolve the yin energy and roasted energy in the large refining field!"

"Um."

Wuma nodded.

All potions that can resolve pain in the refining field require this liquid substance, but the effects of the potions refined between them are different, which are good and bad, which has a greater relationship with other materials, and also have a personal level of drug refining.

"It seems that your refining level should be not low."

Qin Feng did not hide it: "To be honest, with my current refining level, with all my strength, I can at most half-grade divine pills with six pill patterns!"

Wu Ma was secretly shocked. He could actually refine half-grade divine pills, and even refine six more pill patterns. In other words, he was basically not far from refining the quality pills of the divine pill. In the entire starry sky, he was a super expert in alchemy refining, and basically at the level of the Dan Emperor.

"The first is the effusion substance in the Heihe River, so what is the second?"

He asked again.

"The other way is the meat-winged lotus. As long as the meat-winged lotus is neutralized and catalyzed, and supplemented by suppression, it is not difficult to refine. Moreover, because the materials are relatively simple, with my current ability, the number of refining a day is basically at the millions, and the number is still increasing!"

Qin Feng responded.

"In just a few days, I have refined tens of millions of bottles of insulating potion!"

"According to the average number of people in the refining field now, one drop of each undead can basically keep one quarter of the undead in the refining field for about twenty days!"

"Of course, you don't have to worry about this at all. I have a treasure called Taixuan Chen Star Map, and there is a star world in it. One of the stars is covered by me with various treasure medicines, spiritual grass and treasure trees, and there is a meat-winged lotus!"

"At the current number and its growth rate, we can basically maintain the degree to which all the undead spirits in the entire Fengdu City can be refined in the large refining field, so there is no need to worry too much about the material."

Wuma was overjoyed.

He was able to refine more than one million bottles of insulating potions in one day, which was far beyond his imagination. The key was that the basic materials were still sufficient, and he felt a little dreamy.

It was as if God could not see it, and he sent Qin Feng to Fengdu City to rescue the undead spirits who were descended from the law in the city.

"So, can other undead spirits also refine insulating potion?"

He asked again, if others could also refine it, it would be even better.

Qin Feng shook his head: "Although the overall difficulty of refining insulating potion is not too high, relatively speaking, the level of refining has certain requirements. Not to mention reaching my level of alchemy, at least you must be able to refine the Holy Yuan-level elixir to ensure that the refining will not fail, but the refining will be very difficult!"

"After the level is higher, the refining speed will also be greatly improved!"
