Suddenly, Wang Zifeng was attracted by a bubble, which surfaced on the surface of the liquid, but instead of cracking, it stopped there.

Wang Zifeng looked at it, and it turned out that there was another bubble inside the bubble.

Two bubbles are superimposed on top of each other, and the bearing capacity is greatly increased, forming such a phenomenon.

Wang Zifeng's mind suddenly appeared one after another yin and yang changing patterns, they were all bubbles. These bubbles burst instantaneously when they appear individually, but when they are stacked together, the situation is very different.

With a flash of inspiration, Wang Zifeng's internal force pulled, and the yin and yang attributes in the medicinal liquid changed suddenly, intertwined with each other, and turned into circles, which were superimposed on each other to form a huge whole.

The yin and yang attributes of this form are very stable, and they don't need Wang Zifeng's maintenance, so they actually hold it for three seconds.

After that, those yin and yang attributes began to stir again. A huge overall upheaval that will disintegrate and burst at any moment.

Wang Zifeng's internal force was a little, and the huge whole suddenly rotated and turned into a Taiji.

The yin and yang attributes of the entire Dan furnace instantly returned to calm, and there was hardly a trace of change.

Bursts of white smoke rose, and the medicinal liquid in the Dan furnace quickly condensed, turning into a cyan ointment, emitting bursts of fresh aroma.

In the second step, the refining of the liquid into a paste is completed.

Wang Zifeng did not continue the third step, but directly put away these ointments.

It's not that Wang Zifeng doesn't want to carry out the third step and refine the ointment into a pill, it's just that although this batch of ointment is refined, it is very reluctant and can no longer continue refining.

If you insist on refining them into pills, you are just wasting time.

However, with this successful experience, Wang Zifeng believes that he will soon be able to refine the finished Qinghua Dan.

The realization that he had just had a flash of inspiration was not like the last time, it was just a pure coincidence, which completely relied on comprehension and could not be replicated. This time, his understanding is not in the effect, but in the technique.

If Wang Zifeng integrates this technique, he can easily do this kind of thing in the future, turning the yin and yang attributes as Tai Chi, which can not only be used to reconcile yin and yang, but also can be used for the final Ning Dan, which is very practical.

This can be said to be a kind of alchemy secret technique that Wang Zifeng comprehended on his own.

Although Wang Zifeng has not yet fully mastered it, he is also a bamboo in his chest, and he also gave it a name, called "Taiji Ding Yin and Yang".

With this alchemy secret technique, Wang Zifeng was full of confidence and began refining Qinghua Dan for the fifth time.

The refining of the medicine into liquid is still going well, but this time there was a change when Wang Zifeng put in the blood fire saffron.

The moment the blood fire saffron entered the medicinal liquid, Wang Zifeng used the "Tai Chi Ding Yin and Yang".

The yin and yang attributes in the Dan furnace turned into a Tai Chi in a blink of an eye, and the Tai Chi rotated, and the Yin and Yang attributes stirred, instantly crushing the blood and fire saffron.

The liquid medicine oscillated, the bubbles churned, and the Tai Chi fell, which immediately separated the yin and yang attributes in the liquid medicine and integrated into the left and right yin and yang fish.

The attributes of yin and yang enter the yin and yang fish, and as soon as Tai Chi turns, yin and yang are perfectly integrated and return to calm.

After a moment's effort, a layer of green and radiant ointment was refined in the Dan furnace, and the spirituality turned into a Taoist green light, like the brilliance of life, dazzling.

Wang Zifeng made persistent efforts, and the secret technique of Tai Chi Ding Yin and Yang came out again, affecting the Yin and Yang attributes in the Dan furnace, turning these attributes into filaments, winding them into small Tai Chi, and began to absorb the ointment in the Dan furnace.

The suction generated by the Tai Chi Ding Yin and Yang secret technique is not strong, but it is stable and consistent.

Although it couldn't be achieved overnight, those ointments were slowly inhaled into it and slowly condensed into pills.

When the pill was formed, Wang Zifeng breathed a sigh of relief, took out the porcelain bottle, and put away these finished products one by one.

Although the Tai Chi Ding Yin and Yang Secret Technique helps to become a Dan, the effect is not ideal, although its Cheng Dan rate is high, this time it has been refined into thirty-six pieces, but these Qinghua Dan are all defective and inferior products, and there is no existence of medium or even upper grade.

The quality of refining liquid into paste just now is very good, if according to general experience, although Wang Zifeng can't refine so many elixirs, there will be at least some medium-grade elixirs.

If you don't consider the impurities of the pill, it is of course very good that the Tai Chi Ding Yin and Yang Secret Technique can increase the rate of becoming a pill, but considering the impurities of the pill, Wang Zifeng naturally hopes that the higher the grade of the pill refined, the better.

If Doctor Bai knew Wang Zifeng's thoughts, he would definitely sigh and be more popular than dead. It is difficult for others to even become a pill, and the alchemy secret technique that can increase the rate of becoming a pill is simply a divine skill to them, and Wang Zifeng actually dislikes it and lowers the level of the pill medicine a little.

Wang Zifeng took the refined Qinghua Pill, and his attention shifted to the Supreme Medicine God System in his mind.

"Task: Refining Qinghua Dan, refining Qinghua Dan within twenty-four hours, no medicinal qi is allowed to assist. Completed and rewarded with 500 medicine points. ”

"I was surprised that the requirements were so low just now, as long as I refined Qinghua Dan, there would be five hundred medicine points, it turned out that Qinghua Dan was so difficult to refine. Wang Zifeng sighed.

As for the medicinal qi assistance, Wang Zifeng didn't care very much. Although the medicinal qi can increase the rate of becoming a pill, the effect is very weak, if Wang Zifeng does not comprehend the secret technique of Tai Chi Ding Yin and Yang, even if there is the assistance of medicinal qi, it is useless.

Thinking of this, Wang Zifeng looked at another line of prompts.

"Failed to refine Qinghua Dan and gain a proficiency level. ”

"Failed to refine Qinghua Dan and gain a proficiency level. ”

......

"Refining Qinghua Dan is successful, and ten proficiency levels are obtained. ”

This proficiency system is also useless, and it may be useful in the future, but it is not yet to be counted on. The proficiency of each elixir is calculated independently, and it is unknown how long and what month it will take to complete them.

Wang Zifeng shook his head, poured out a Qinghua Dan, and swallowed it into his stomach.

A wave of medicinal power suddenly stirred Wang Zifeng's whole body from his abdomen.

The internal force of Wang Zifeng's whole body rotated, and the "Ten Thousand Medicine Divine Codex" completely refined these medicinal powers, turned them into internal forces, and integrated them into Wang Zifeng's dantian.

Wang Zifeng only felt that his internal strength had skyrocketed, but in a moment, he actually increased his strength by two times.

"Take the next grade Qinghua Dan, and reward fifty medicine points. ”

After looking at this prompt, Wang Zifeng nodded and thought, "Qinghua Dan is really more powerful than Qingxin Dan. It's just a lower grade, and the medicine points you get are the same as the middle grade Qingxin Dan. ”

Although the effect of Qinghua Dan is amazing, if Wang Zifeng's skill is to go further and reach Dacheng, these thirty or so are still not enough.

Wang Zifeng put away these pills and looked at the remaining medicinal materials.

Alchemy continues.

Although he has comprehended the secret technique of alchemy of Tai Chi Ding Yin and Yang, refining Qinghua Dan is still full of problems, except for the occasional Yin and Yang mutations, the final Cheng Dan is the key to stopping Wang Zifeng.

Wang Zifeng tried not to use the Tai Chi Ding Yin and Yang Secret Technique to condense the pill, but the effect was not ideal, sometimes it failed, sometimes it succeeded, and even if it succeeded, it failed to refine the medium-grade Qinghua Dan as Wang Zifeng expected.
