These medicinal incense were mixed together, and there were dozens of them, in other words, if they were a disciple of any sect of immortals, they could distinguish the smell and distinguish more than ten kinds, they were all the brightest ones in this way, but Fang Ling could easily distinguish thirty of them just by pondering it.

The reason is not difficult to understand, Cun Ding is like another heaven and earth independent of heaven and earth, in addition to the various spiritual materials picked back by the mink back then, but also because of the effect of the cycle of heaven and earth, according to the geographical environment, climatic conditions and the rich atmosphere of heaven and earth, naturally grow out of various spiritual materials that are difficult to find in the mortal world, plus Huo Junyuan is rich in knowledge, distinguish these medicinal materials one by one, and impart the knowledge to Fang Ling, so Fang Ling's views on medicinal materials are beyond the reach of even the best Xianmen disciples.

Fang Ling closed his eyes and continued to distinguish, and the number of distinguishing medicinal materials appeared in his mind, the number of which was as many as fifty, most of these medicinal materials were cold and evil poisonous things, and some were neutral, mild, and strong.

The drug will be the most cooperative, different medicinal materials will produce different effects, and the way of alchemy, different medicinal materials have different treatment methods, cooperate with each other, and then cooperate, the process is quite complicated, and it is not easy to simply see the clues from the medicinal materials.

However, this was not difficult for Fang Ling, in terms of his understanding of medicine, he was far above those of his peers, and even inferior to the martial arts of the Heavenly Fusion Realm.

After carefully discerning it, Fang Ling immediately understood that Jiang Yuecheng was refining a poison pill, for ordinary martial artists, taking the poison pill would kill them instantly, but for martial artists who cultivated evil paths, as long as they used it properly, it would greatly improve their skills.

It's just that the toxicity of the main materials is too heavy, and it is difficult to neutralize it with other medicinal materials, so Jiang Yuecheng is thinking about how to solve the problem, disturbing Jiang Yuecheng, who is already hot-tempered, at this juncture, will undoubtedly hit the muzzle of the gun, but Fang Ling has no other way, and the longer he stays in Taiyan Palace, the more dangerous it becomes.

Fang Ling frowned and thought for a while, untied his waist bag, and took out a snake green grass from the inch, as the master of the inch, he also became the master of the inch, as long as the mind moved, the things needed will automatically break away from the inch, it is very convenient, and there is no need to enter the inch.

After taking out the snake green grass, Fang Ling strode towards the alchemy room, and when he came to the front and back of the door, he knocked lightly on the door, and said loudly, "May I ask if Elder Jiang is here?"

In a few moments, the door opened, and out came a forty-year-old man in a green robe, with an ugly face, an egg-sized sarcoma on his left forehead, and a grinning mouth showing a mouthful of large yellow teeth.

Jiang Yuecheng was a little angry because he couldn't solve the method of combining medicinal materials, and when he heard that someone dared to disturb him, he added fuel to the fire, and as soon as he came out, he didn't mean to ask at all, so he was ready to beat this young man who didn't know the height of the sky and couldn't get up.

But before he could make a move, Fang Ling handed over the snake green grass.

The snake green grass is no more than the thickness of a thumb, about half a foot long, like a snake body, with hidden markings, and the whole body is turquoise, exuding a green jade-like luster.

You must know that the snake green grass is a rare variety even in the mortal spirit grass, although it lives in the extremely cold underground, but it has become positive due to the extreme cold, and many important fourth-level pills are used as neutralizing materials.
