Chapter 138 Liangshan must have its own Thunder Department
The unorthodox and side doors are the methods to protect the Tao.

Gongsun Sheng's palm thunder really shocked Cao Jie.

This was completely different from the thunder magic he had imagined.

Before Ru Yunlong made his move, the palm thunder in Cao Jie's heart was like lightning and snakes, thousands of birds singing, and thundering.

Even if he cannot learn Zhang Chulan's Yang Five Thunders because of his virginity, he should be able to learn Zhang Lingyu's Yin Five Thunders!

But what does this mean?
Royal thing? !
As the saying goes, "It's always good to have many skills." Although Cao Jie was very critical of this unconventional thunder technique in his heart, he did not despise it and planned to learn it first.

Following Gongsun Sheng's detailed explanation, Cao Jie gained a deeper understanding of palm thunder.

First of all, this is indeed an unconventional technique that uses mental power to control objects, but it is not as simple as just controlling objects.

The compression of telekinesis and the fine control of telekinesis over spellcasting materials are not something that ordinary spiritual practitioners can master.

Compared with this, flying knives and flying swords seem extremely simple and easy to learn.

Secondly, the strength of the palm thunder is related to the cultivation level of the caster, and more to the casting materials.

Why are Taoists so obsessed with refining elixirs?
Especially for Taoists who practice external alchemy, not only can the elixirs they refine assist their practice, but the by-products of alchemy, such as gunpowder, can also be used to protect their practice.

This is how the secret technique of palm thunder was born.

Pure thunder magic is too difficult to practice. Even after practicing for a decade, you can only strike twice, and you may not be able to kill someone.

The price/performance ratio is really too low.

Although this palm thunder is an unorthodox method and cannot lead to immortality, it is easy to practice!

If only powdered gunpowder is used as the casting material, its power will naturally not be too great, but if it is replaced with a granular formula, the power will increase exponentially.

"If I use nitroglycerin as the material for the palm thunder spell..."

Cao Jie glanced at Gongsun Sheng and thought to himself: So you are interested in my nitroglycerin. You are indeed a master of the fifth level of Yunshen. You actually saw through it... How do you make this thing? Glycerin is made by putting it in nitric acid? Then how is glycerin made? Nitric acid can be made...

"Forget it. I'll give the Nobel Prize of the Song Dynasty to you, Gongsun Sheng... No, no, if Master Na Luo finds out that you're not doing your job and neglecting your cultivation, even if he doesn't cause trouble for me, he'll still take you back to Erxian Mountain to practice hard."

To be honest, Liangshan cannot be without Gongsun Sheng!
Cao Jie pondered for a moment, nodded and said, "Mr. Gongsun, this thunder method is very much to my liking. But the power of the granular gunpowder is still a little weak. I have a unique gunpowder that is several times more powerful than granular gunpowder and is most suitable for performing palm thunder."

Hearing his brother say this, Gongsun Sheng felt relieved.

The reason why he performed so hard tonight was because of that mysterious and unknown explosive.

But even Liu Huiniang didn't get the recipe. If he asked for it rashly, it would make it difficult for his brother. It would be in the wrong to give it to her, and it would be in the wrong not to give it to her. This would hurt the brothers' feelings in vain.

Now, finally... all my efforts have paid off!

At this time, Cao Jie changed his tone and said, "But... I don't know how to refine the gunpowder. If Mr. Gongsun needs to use it to perform palm thunder, I can provide some every month."

Gongsun Sheng raised his eyebrows and asked, "Brother, you don't know how to make it?"

"It's brought by the soul of the previous life. It's essentially a kind of medicine."

Cao Jie flipped his palm and used his blood and essence to condense a small white lozenge.

"medicine?"

"It can effectively treat angina pectoris. The explosive property in it is less than one percent. Therefore, even if it is purified, it is already very difficult." It is indeed difficult. Cao Jie had no way to purify it before, until the appearance of the "Healing the World" purple gold gourd of the [King of Medicine], and then he could barely obtain pure nitroglycerin through this magic weapon.

The small purple gold gourd is a rule-based magic weapon that directly increases the medicinal properties.

When this rule is applied to nitroglycerin, the so-called enhancement of medicinal properties becomes increasing its purity.

One lozenge contains about 0.3% nitroglycerin. After a month, Xiaohulu can increase it to about 10%.

This is how the previous explosion happened.

Gongsun Sheng took the small white pill with both hands respectfully and solemnly, and used his telekinesis to sense it carefully, and indeed, he discovered a substance he had never seen before.

"It's something I've never seen before... Even Master's alchemy room has never seen such a substance. Brother, can I take it to study?"

Cao Jie didn't care and advised: "You can study it, but don't get obsessed with it! The side door method of protecting the way is enough, don't spend a lot of time on it just to pursue that little power. In my opinion, using granular gunpowder to perform palm thunder is enough at this stage."

"My brother reminded me that I would not become addicted."

Looking at Gongsun Sheng's departing back, Cao Jie also walked back.

Nitroglycerin decomposes when exposed to light, so it is impossible for him to become addicted to it.

As for spending a lot of effort to develop nitroglycerin and become the Nobel Prize of the Song Dynasty, Cao Jie has no such idea for the time being.

If that kind of thing comes into the world, it can change the world, but my arms and legs are too thin now and I can’t protect it.

When I returned home, the laboratory that I had specially cleaned up for Liu Hui Niang was still brightly lit.

The three main materials for black powder are not difficult to purchase, just spend money.

But the saltpeter was not pure enough, the sulfur was not pure enough, and the charcoal needed to be ground into carbon powder. Liu Hui Niang had to figure out the process of these purifications herself before she could put them into mass production.

The purification of saltpeter is very simple. You just need to add wood ash into it, heat it in a large vat, and then what will come out after analysis is saltpeter.

As for the purification of sulfur, it was a bit troublesome. Liu Hui Niang found a crucible, threw the sulfur in it and put it on the fire. When the sulfur was boiling, she found a large wooden trough with running water above to cool it down, and covered it above the crucible.

The sulfur vapor collected in this way is pure sulfur.

As for charcoal, you need to use willow branch charcoal, which needs to be ground into a fine enough powder.

After the three things were purified with such great effort and painstaking care, and then mixed in classic proportions, they became a pile of pure black powder.

At this moment, the preparation of granular gunpowder has reached a critical step. Liu Hui Niang beats the egg white into the powder and rolls it back and forth in the sieve.

After tumbling for a stick of incense, it became small particles. After passing through a sieve, what came out were treasures the size of rapeseeds.

Cao Jie didn't disturb her, just watched quietly.

After she finished the last step, she said, "It's getting late."

"Husband, wait a minute, it will be ready soon!"

Liu Hui Niang played with her treasure obsessively, then took out a part of it, lit it with a "puff" sound, and observed its burning speed and the amount of residue left.

Looking at his wife who works so hard, Cao Jie is filled with emotion.

If she really established the Liangshan Leibu, it would not be an exaggeration to make her the legal wife!
