Chapter 140 (1/2)

On the back mountain, Xiao Yi comprehends the five elements of ningdan.

Today, Yi's teaching has benefited him a lot.

At least it won't be like last night, like reading the book of heaven.

It has to be said that Yi Lao's teaching ability is really powerful.

Those obscure knowledge of refining medicine, complex and mysterious combination of herbs, in his mouth, easily became concise knowledge.

Dan medicine refining, the way to remove impurities.

It is in the process of alchemy, when the pill is about to coagulate the pill, add the monster inner pill.

In the process of refining pills, the added Tiancai Dibao has various attributes more or less.

For example, one hundred year old Scrophularia, earth attribute; demon blood burning heart fruit, fire attribute; Peiyuan Zhuguo, wood attribute; hemlock branch, metallic...

and materials for refining xuepi Dan are mostly ice materials.

Therefore, refined pills, in fact, more or less, will have a little attribute.

The five elements record of Ning Dan is to remove the impurities of pills through the internal elixir of monsters by relying on these attributes.

Of course, there are impurities in pills. The inner elixir of demons also has impurities and brutal smell.

However, the five elements are complementary and mutually exclusive.

For example, a pill with ice attribute.

In the process of coagulating pills, adding ice attribute monster inner pill can greatly increase its own ice attribute.

The impurities were ”squeezed out” before the complete Dan formation.

This is called mutual generation.

As for the impurities and brutal breath on the ice monster inner pill, you only need to add the fire attribute demon beast inner pill to fight with ice and fire to eliminate the impurities and brutal breath.

This is called Xiangke.

As a result, the impurities on the pill and the impurities on the monster pill can be completely eliminated.

To sum up, it is a sentence.

Mutual generation, in addition to the impurities in pills; Xiangke, in addition to the impurities in the internal elixir of monsters.

This is the principle of Ning Dan Wu Xing Lu, which is also what Yi Lao taught today.

”It's no wonder that in addition to daggers, poisons and finished pills, there are so many demon blood essence and demon inner elixir among those seized before.” Xiao Yi said to herself in a deep voice.

”Shadow building, many killers. Demon blood essence is used to medicate killers, improve their accomplishments, or for other purposes. ”

”The internal elixir of the demon beast is used by the pharmacists in the shadow building to refine pills without impurities.”

The five elements record of Ning Dan is not unique to the split Sky Sword school.

According to old Yi, this is a method that some advanced pharmacists must learn.

However, in the whole Beishan County, there are only three people who can do this, not including the split Sky Sword sect.

These three were all pharmacists of various forces, one in the demon hunting hall, one in the shadow building, and the other under the command of Beishan Prefecture.

Although these three men are all five grade pharmacists, they are far less than the medicine hall elders of the split Sky Sword sect.

So even if these three people had this skill, they were very slow, even pitifully slow, in refining pills without impurities.

Let's get to the point.

Principle to principle.

The principle is taught by Yi in one day. It is not difficult and easy to understand.

But it is very difficult to implement it.

A pill, with a kind of attribute, it is necessary to add two monster internal elixir of mutual restraint attribute.

But in fact, pills are made from many kinds of natural materials and treasures.

So there is more than one attribute.

This requires the addition of more monster Neidan.

The more the number of demon beast Neidan, it means that the attribute has become more.

Therefore, the combination of different attributes becomes quite complex.

Tiancai Dibao is burned by high temperature flame in the alchemy furnace. In fact, most of its properties have been burned out, and only a little remains.

And this little bit is the residual property of all kinds of natural materials and earth treasures.

Which of these attributes is stronger or weaker? Is the fire attribute more prosperous, or is the wood attribute more prosperous?

At this time, it is necessary to add the inner elixir with different energy levels.
