"What happened?" Ye Chang overtook the horse and ran directly into Zhuangzi.

Liu Laitou and others who were in charge of Zhuangzi's affairs just got the news that the young master would come, and before they rushed to Zhuangzi, they got Ye Changling and rushed to the 'laboratory'.

This time the explosion was louder than usual. From a distance, the group of disgraced craftsmen were extinguishing the open flames. Ye Changling didn't hesitate to get off his horse and join their firefighting team.

The open fire was quickly extinguished. Seeing Ye Changling appear, these craftsmen first shouted "Master" happily, but when they saw the messy reactor at random, they immediately lowered their heads. Knock knocked, but honestly dare not speak.

"Is no one injured?" Ye Changling looked around and asked.

Hearing Ye Changling's question, everyone present shook their heads hesitantly.Ye Changling heaved a sigh of relief, it was not easy to find a group of craftsmen, especially after working together for a long time.Moreover, the level of medical and health care in this world is too bad, once you get injured, it is the biggest trouble.

"East Ye's family." Looking at the mess, Old Craftsman Zhang was a little ashamed.

"It's because Ye has forgotten the time." Ye Changling only gathered here spontaneously because he hadn't summoned this group of craftsmen for a long time, and they were afraid of losing their good job.

"Let's clean it up. There is no rush to make this fertilizer. Since the reactor has been damaged, let's put it on hold for a while." Ye Changling was actually a little desperate. Sure enough, he only knew the theory. If the industrial level cannot keep up, he would still fail. up.

It was also the success of the previous honeycomb briquettes and steel that made him feel a little bit elated. If this industrial synthetic ammonia fertilizer could succeed so easily, it would not have become a great invention of the [-]th century.

And because of the air pressure, it is easy to explode. Although what they do is carried out in an empty place, there is always a danger of poisoning.

Thinking of this, Ye Changling didn't worry too much about this issue. Just as he was about to introduce Chu Zhengji to Old Craftsman Zhang and the others, Old Craftsman Zhang suddenly smiled embarrassedly.

"When we go back to Ye Dong's house, we seem to have made 'chemical fertilizer', but we don't know if what we made is what Ye Dong's family wanted." Old craftsman Zhang said so, and other craftsmen also took advantage of the trend to make the things they made during this time Hold it up.

ammonium sulfate.

Excellent nitrogen fertilizer suitable for most soils and crops.

The world only knows that high-yield hybrid rice can feed countless people, but they ignore the emergence of nitrogen fertilizer, which is the cornerstone of increasing food production.

"This..." Ye Changling stretched out his hand to grab some, even though the smell was terrible, compared with the ammonium sulfate crystals he saw in his previous life, there were too many impurities, but Ye Changling felt his heart was beating crazily.

"Chen Si, bring the milk." Ye Changling felt that his voice was trembling.

"Yes." Chen Si ran away in a hurry when he heard the voice.

Half a moment later, Chen Si walked over with a bowl of milk carefully.

Chu Zhengji saw a group of people excitedly surrounding them. Ye Changling was in the middle. He closed his eyes and let himself breathe steadily. He put the white lump that looked like salt in the hand of the old man he saw before into the milk. among.

Immediately, something that caught Chu Zhengji's attention happened, the milk gradually coagulated and precipitated.At this time, there was a cheer from the crowd.

Old Craftsman Zhang also had a proud face. Although they had done similar experiments many times, it was completely different to be able to succeed in front of the owner.

Seeing the salting out of the milk, although other methods such as heating are needed to verify whether it is ammonium sulfate, Ye Changling already knows that it is this.

"Have you written down the method?" Ye Changling asked as he put down the milk.

"Yes."

……

Chu Zhengji was surrounded by Ye Changling, the group was already discussing in full swing, Chu Zhengji curled his lips, and looked at Chen Si who had been squeezed aside.

"Benefactor Chen." Chu Zhengji called Chen Si.

"Yes, Layman Chu." Chen Si was immediately flattered. For some reason, every time he saw this Layman Chu, he never dared to make a mistake, obviously the other party was just a wandering Taoist.

And this Layman Chu is really good-looking, even a big man like him always feels ashamed every time he sees him.

"I think Chang Ling won't be able to get away for a while, why don't Master Chen show me around." Chu Zhengji suggested.Being left out by the host's family, ordinary guests would always feel slighted, but after getting along with each other for this period of time, Chu Zhengji understood some of Ye Changling's character. Although he didn't express it on the surface, Ye Changling was very happy at the moment.

Chu Zhengji subconsciously didn't want to disturb Ye Changling at this moment.

……

Following the conversation with Zhang Laojiang and others, the plan from the implementation of the plan to the mass production in the future has also been formed in Ye Changling's mind.Ye Changling finally knew that Old Craftsman Zhang and others had been here all this time, conducting experiments.This group of people endured the desperate number of experiments and proceeded step by step. Ye Changling didn't know how to feel for a while.

However, Ye Changling didn't expect that even though Old Craftsman Zhang and the others failed hundreds of times in doing these things, there was no reason for them to be discouraged. It was just because they had full confidence in Ye Changling, and they blindly believed in Ye Changling.I believe that Ye Dong's family will not make mistakes.

On the other hand, even with a little understanding, Ye Changling probably doesn't understand that there is no need to serve the arduous corvee in the court, and live without enough food. Now, with food and money, the boss still treats their families differently. This kind of care, what does it mean?

It was also after looking at their records during this period that Ye Changling realized that they had made some 'useless' things.

nitric acid.

Ye Changling looked at the poisonous water called "itchy water" by craftsmen, and was surprised enough to see ammonium sulfate, but the thing in front of him really made him not know what to do.

nitric acid.

Although it is extremely small, it has indeed been produced.

Nitric acid is widely used in industry, but the moment he saw it, only four words appeared in Ye Changling's mind - nitroglycerin.

In the last life, it was obviously a product for civilian use, but in the end it was carried forward in the war.

Ye Changling looked at the sky, and before they knew it, they had already missed lunch, and it was already evening.

"It's getting late, everyone has worked really hard recently, everyone go and rest first." Ye Changling looked around, and the craftsmen were very enthusiastic. They probably didn't know that they made it unintentionally and thought it was rare to keep it. What does a small glass of 'poison water' mean.

The joy brought about by the success of ammonium sulfate had faded away, and Ye Changling returned to the room solemnly holding the small cup of nitric acid.

Then, on the way, he met Chu Zhengji who had already turned around.

"Layman?" Ye Changling remembered at this moment that he had forgotten Chu Zhengji and the others.

"I'm really sorry, Chang Ling..." Ye Changling just apologized, but was stopped by Chu Zhengji.

"It's okay, Chang Ling is just in the right mood, and Ji doesn't want to disturb him. But Ji went for a stroll just now, and never..."

"It was Chang Ling who acted on a whim and forgot the layman's fault, but the layman didn't blame Chang Ling."

"I don't know what is the 'ammonium sulfate' that Changling talked about during the day?" Chu Zhengji took advantage of the situation and changed the subject.

"Rong Changling's keeping it a secret, laymen just wait for the results to know." Ye Changling smiled.

"Well, Ji will wait and see." The corners of Chu Zhengji's mouth curled up slightly, under the moonlight, his eyes were deep, with a hint of probing.
