"How? Is Mr. Sima willing to stay? ”

In Li's house, Wu Ning was talking to Meng Cangsheng, who had just turned around.

"Don't worry!" Meng Daoye was complacent, "This Daoist is out of the horse, how can it not be done?" ”

"Huh?" This surprised Wu Ning a little.

"It's done? How do you say that? ”

In Wu Ning's impression, Meng Cangsheng's senior brother is indeed a person who is indifferent to fame and fortune and only cultivates Taoism. can say that he can be moved to help, it is completely because of face.

Moreover, it was also said at the beginning that Sima Chengzhen only helped here, and he left as soon as the matter was accomplished.

If you have to leave Sima Daoye behind, it is difficult for some strong people.

In Wu Ning's expectations, even if Meng Cangsheng said that Sima Chengzhen would stay, it would probably take some time.

But...... So easy to get it?

"How did you say that?" Wu Ning looked curious.

I saw Meng Daoye pouting, "I'll tell him, if he dares to go, then he won't want the recipe of thunder to solve water!" ”

Wu Ning: "Poof!! ”

Is that okay?

Originally...... It was a joke at first, okay?

This matter has to start a few years ago, when Wu Ning first saw Sima Chengzhen and found that this was a "wonderful person" who was obsessed with alchemy.

Why do you say "wonderful people"?

Because, it was not Wu Laojiu who went to him for planning at all, but Sima Chengzhen himself came to the door through Meng Cangsheng.

What are you doing?

Pull Sponsorship!

This alchemy has tossed up the family wealth before becoming a monk, and the little land that Pan Shizheng left him to support his master has also been sold out, and the poor jingle is about to eat.

There was no way, I heard that the junior brother was doing well, so I took the initiative to come to the door to seek relief.

Well, it is to let Wu Laojiu pay for him and continue to refine the pill for him.

And Wu Ning is indeed not bad for these little money, and he is Meng Daoye's senior brother.

So, next to Wu Ning's big money, Sima Chengzhen immediately changed from a beggar to a Taoist master.

Not to mention, Wu Ning's money is not wronged, and after coming into contact with this Sima Daoye, he has also gained a lot of knowledge.

In later generations, Joseph Needham of England mentioned in "The History of Chinese Science and Technology" that Chinese alchemy is one of the important origins of chemistry in the world.

Before, Wu Ning hadn't taken it seriously, but after contacting Sima Chengzhen, he understood the truth of this sentence.

For example:

The most commonly mentioned in Taoist alchemy is also the "Nine Turns Golden Pill" commonly used by later generations of immortals, what is going on?

What is the "Nine Turns Golden Pill"?

The "gold" in this does not refer to gold, nor to color, but to an important material for alchemy - dansha.

The ancients found that dansha is a very interesting thing, and when it is calcined in a fire, not only will it not become embers, but it will give birth to metal.

Moreover, the metal is not solid, but a liquid like water.

If there is a wonderful method of refining and burning, add gold and stone, and turn it into dansha again.

Therefore, the Taoists followed this method, refining the dansha into "golden water", and then reacting into dansha.

On this basis, coupled with the herbs, trees, gold and stones that they believe have the effect of health preservation, they repeat it nine times, which is the "Nine Turns of Jindan"

And this method of nine-turn alchemy is recorded in the "Shennong Materia Medica".

What is it?

Dansha is mercury sulfide!

And the liquid metal is naturally mercury, isn't this the reduction reaction of mercury sulfide and silver?

This is also the earliest recorded chemical reaction in human history.

Therefore, in Wu Ning's opinion, this Sima Daoye is not only a Taoist priest, but also half a chemist, right?

Out of this heart, Wu Ning took a high look at Sima Chengzhen and was willing to talk to him about things that had not yet appeared in this time and space.

Like what kind of black powder or something, Sima Daoye has already come up with it under the guidance of Wu Ning.

It's just that Wu Laojiu Chemical is also a half-ass, he forgot the ratio of saltpeter, sulfur and charcoal, and the things he got out smoked and couldn't be blown up, so he could only let Sima Chengzhen try it slowly.

Originally, Sima Daoye's life was very beautiful, plus they were all stinky and shameless, and they were cheeky enough to take Wu Ning's and not help Wu Ning's errands, Sima Daoye could also do it.

asked Sima Chengzhen to help this time, and he couldn't come alive or dead.

However, during the chat, Wu Ning heard that he had refined the pill and the demon barrier, and he needed rootless water to draw rootless fire to refine the pill.

Well, Wu Laojiu played a trick.

Rootless water is easy to find, that is, rainwater that has not landed.

But you don't have a place to get the rootless fire, do you? Do I have it?

I'm going to make a rootless fire, don't you say it's a coincidence?!

With this threat, it can be regarded as inviting Sima Chengzhen.

However, I didn't expect that Sima Daoye was a little persistent, and he was willing to stay for this rootless fire.

Well, it can only be said that Datang's salary level is a bit low, and a small experiment of electrolysis of water to produce oxygen and hydrogen fooled Sima Chengzhen.

In the next generation, children will know this, okay?

The water is connected to the electric current, and the positive electrode produces oxygen and the negative electrode produces hydrogen.

I learned it in junior high school, and even Wu Laojiu knew it.

As for how does the electricity come from?

It's easy, too! Doesn't cutting magnetic field lines produce induced electricity?

Well, just a little thing, how hard is it?

“......”

Wu Laojiu is a turtle again.

Electrolysis of water requires direct current, while cutting magnetic field lines is ...... Alternating current.

......

——————————

After getting Sima Daoye, Wu Ning can't do anything for the time being.

Although he knew that Wu Sansi would never be fooled by this, he must have doubts.

However, now that the enemy is in the dark, I am in the light, and Wu Ning does not dare to act rashly, so he has to wait and see.

It's just that he wants to "live" quietly for a few days, but someone doesn't want him to stop.

Wu Zetian has been pondering a thing recently:

Since......

Since you Mu Zijiu is so powerful, shouldn't I arrange an errand for you to do?

But what kind of errand is arranged?

That's the problem.

Originally, with the old lady's dislike of Mu Zijiu, she couldn't wait to send him to the Imperial Horse Prison to feed the horses.

However, something happened recently that made the old lady change her mind.

Mu Zijiu is useful! And it's useful!

As for how to use it, Wu Zetian has never thought about it.

For this matter, the old lady also talked to Shangguan Xiaowan several times, and even asked Taiping and Wu Chenghei for their opinions.

But the jury has never been reached.

Until recently, the old lady suddenly came to "inspiration".

"Let the child study...... Go to Chang'an to make a city supervisor! ”

What the?

Shangguan Wan'er was shocked!

Princess Taiping was shocked!

Even the special Wu Chenghei was shocked!

"Your Majesty!!" Wu Chengsi hurriedly shouted, "Chang'an is a big matter, Wuchuan is afraid of being embarrassed!" ”

The subtext in my heart is:

That's a fat shortage, how can you give it to him?

And Taiping also surprisingly agreed with Wu Chengsi this time.

"Mother, do you want to ...... Think again?? ”

Not only was it a fat shortage, but it was a fatal errand.

If you don't get it right, you're going to die!!

......
