Chapter 983
"What...what Lin...what Qing?"
"What the hell was that Daoist Master Zhang just mumbling? I didn't understand a single word."
The cotton cloth could not be burned. This was something that no one had ever heard of. When everyone saw it, they were naturally curious and wanted to hear what was going on.
It’s a pity that after listening to the whole long string, I didn’t understand anything.
"Brother Feng, Brother Lin, you two read a lot of books, can you understand?" Someone subconsciously asked for help from Feng Xu and Lin Yishan, who seemed a little embarrassed at the moment. The two were born as Beijing officials, so everyone naturally thought they were the most knowledgeable and experienced.
The others also looked at Feng Xu and Lin Yishan with curiosity.
However, in this era, there was no concept of this word at all, so no matter how high one's knowledge was, it would be useless. Feng Xu and Lin Yishan looked at each other and shook their heads.
"I am not very knowledgeable."
"I don't know the true meaning of Master Zhang's words."
Everyone was greatly disappointed for a moment, but some spread their hands, shrugged, and said with a smile: "It can prevent cotton cloth from burning. It must be a magic trick!"
The people around him laughed and echoed, not understanding why, "Hehe! Your Majesty knows these immortal arts!"
"..."
While everyone was discussing in confusion, Zhu Yunhuan was thinking carefully and recalling the past. After pondering for a moment, he looked up at Zhang Yuqing and the others and said:
"You only noticed what solution was used and how it was dried."
“But have you ever paid attention to the details?”
"For example...when soaking cotton cloth, does the pH value and temperature of the solution affect the adhesion?"
"Besides that, what is the most suitable drying temperature range? Often, low-temperature drying will dry the clothes just as well as high-temperature drying. The final results may look the same from the outside, but the effects may vary greatly."
"Also, based on your current experience, you can probably tell that the reason this cotton cloth can't be burned is similar to the reason why a tinderbox can't be extinguished. Both involve chemical substances attaching to the substance, changing its properties."
"Are the cotton and linen fabrics themselves clean? Are there any grease, wax, or impurities attached to the surface? These factors will also affect the adhesion and the uniform penetration of chemicals. Have you considered this?"
Compared with impregnated fuse, the processing process of flame retardant cotton is obviously more complicated.
The specific details and data.
He really doesn't remember it very well.
However, since Zhang Yuqing already had the finished product that was made by accident, and he had explained the general steps to Zhu Yunhuan, Zhu Yunhuan naturally had an idea in mind.
Therefore, Zhu Yunhuan only needs to list all the variables that may arise in the process and the details that are easy to overlook.
Just leave it to Zhang Yuqing and his group to debug it slowly.
Zhu Yunhuan finished speaking.
The people here were already confused, and there seemed to be more and more question marks in their heads, and the eyes looking at Zhu Yunhuan were becoming more and more confused.
"Hiss... Temperature? Acid?... Reduce..."
"Your Majesty, what are you talking about?"
"Why do I feel like I'm reading a divine book?"
Everyone looked at each other, and saw confusion in each other's eyes.
And the other side.
Zhang Yuqing, Liu Yuanran, Yuan Gong, and Ma Rui all had looks of serious thought on their faces. They all looked at Zhu Yunhuan intently, frowning, as if they were afraid that they had missed or forgotten every word Zhu Yunhuan said.
Wait until Zhu Yunhuan finishes speaking.
Several people exchanged glances with each other, each showing a look of sudden realization.
"Your Majesty... you are absolutely right! I was shortsighted, only seeing the superficial steps and not paying attention to the details!"
"Originally, several disciples in the Alchemy Department racked their brains for a long time, following their own preconceived steps over and over again, but to no avail."
"Now, after listening to Your Majesty's words... I feel suddenly enlightened!"
Several people showed joy on their faces.
As the saying goes, those who are involved in the matter are often the most confused. They had been clinging to the superficial steps, but no matter how many times they repeated the previous process, it was useless. It seemed like they had reached an end, a dead end, and could not see the way forward at all.
