Seeing this, Yun Qingyan quickly removed the flames and found a ball of black unknown medicine paste floating in the Qingxuan tripod.

Refining failed.

"Xuanming Grass...Zhuguo..." Yun Qingyan counted the refining materials little by little and recalled his refining steps, and frowned slightly. No matter whether it was the material or the order of input, there was nothing wrong with it.

How could it fail?

Xiao Xuan stayed aside, staring with his breath, not daring to disturb Yun Qingyan.

When the owner is thinking, he hates others to interrupt it the most.

"Refine it again." After thinking for a long time, he still couldn't find the reason for the error. Yun Qingyan muttered in his heart and started to refine the Na Ling Pill again.

Fortunately, she prepared enough materials and could refine ten copies. She didn't dare to be proud of the first time she refined the Na Ling Pill. She only used one portion of the materials at a time, otherwise, she would probably not even have the materials to refine.

Cangming was gone and distracted her energy. This time, she was more careful when refining Yun Qingyan. Her mental power woven a fine net and covered the fusion powder. As long as the medicinal properties change during fusion, she could sense it as soon as possible.

"Puchi!" Suddenly, the medicine paste that had gradually merged perfectly suddenly sounded and turned into a ball of slag again.

"It turned out to be Yun Lingcao and Zhu Guo." Yun Qingyan stared at the ball of medicine and fell into deep thought.

She didn't show up when she first refining, but during the second refining, she clearly sensed that the refining failure was when Yunling Grass and Zhu Guosheng merged.

Once the two collided, the medicinal properties fluctuated greatly, affecting other medicinal materials, resulting in the complete failure of refining medicine.

But Yun Qingyan also knew that the prescription of Na Ling Dan would not be wrong. The key now lies in how to control the stability of Yun Ling Herb and Zhuguo so that they can merge smoothly.

Yun Qingyan pursed and began to go through the Hunyuan Medical Sutra in his mind.

When he read the medical scripture in his mind, Yun Qingyan suddenly felt guilty.

At first, she wanted to obtain the Hunyuan Medical Classic, just to understand the poison on her body.

After getting the method to suppress the Nine Sha Demon Poison from Huang Yan, she threw away the medical scriptures that can be said to be both a martial art and a medical book, which led to the Hunyuan Medical Sutra being only the first level, which is really a sin.

This Hunyuan Medical Sutra was really ruined in her hands.

It seems that if she has time, she still has to study medicine and refine her body, and cannot just focus on practicing the Seven-Star Body Refining Law. Now she can still rely on her old capital. When her realm rises a little more, the first level of the Hunyuan Medical Sutra is a bit insufficient for her.

"Yunlingcao is cold in nature, and red fruit is hot in nature. When fusion is carried out, it must be neutralized with Long Kuai Water. Otherwise, the collision between the two will cause the medicine to conflict and the refining will fail." Yun Qingyan slowly studied the information on the Hunyuan Medical Sutra, and his eyes flashed.

Not all spiritual medicines with cold and heat will be buffered with special "buffers" like Yunlingcao and Zhuguo. Usually, as long as the alchemist's mental power is strong enough, it is enough to be more careful when fusion is combined.

These two herbs are considered two enemies. No matter how mental power of the alchemist is, as long as there is no "buffer" in it, the medicinal properties will conflict and lead to failure in refining.

Fortunately, although Longkui water is relatively expensive, it is not rare and is sold in ordinary pharmacies.

Yun Qingyan cleaned up the medicine residue that failed to refine medicine, took Xiaoxuan out to buy Longkui water, and solved the lunch problem by the way.
