Time Travel: After Seizing the Throne, I Lead the Ming Dynasty to Take Off

"Thank you even more for your kindness and generosity, Your Majesty!"

"There's no such thing as a free lunch in this world. The needle gun must be a good thing. I also believe that Your Majesty will definitely not deceive us. If it really can be made into a product one day, I will not mind if I suffer some injuries."

"I shall serve Your Majesty with all my heart and soul, and I shall do my duty for the Ming Dynasty!"

The words were beautifully spoken, and the two people's voices were particularly powerful.

This made Zhu Yunhuan at a loss for words. However, as the two finished speaking, Zhang Yuqing, who was standing respectfully behind Zhu Yunhuan, stepped forward and said, "Your Majesty, I have something that may be of some use to you."

Zhu Yunhuan then remembered.

Zhang Yuqing, Liu Yuanran, Ma Rui and others were still here. They had just rushed over, as if they had something to ask, but were interrupted by the sudden explosion.

Zhu Yunhuan turned his head and asked with interest, "Some use? You mean... useful in dealing with their dangerous research work?"

Zhang Yuqing immediately lowered his eyes and nodded: "In reply to your Majesty, that's right!"

"Tell me about it." Zhu Yunhuan also became interested.

"That's exactly it." Zhang Yuqing took out a medium-sized piece of cotton cloth and a tinderbox from his sleeve. "Your Majesty, please wait a moment and watch."

After saying that, he blew up the tinder in his hand, and a medium-sized flame burned on the top of the tinder. He then brought the tinder close to the cotton cloth he had just taken out, so that the flame on the tinder directly touched the cotton cloth.

Seeing his actions, everyone else was confused: Using a tinderbox to burn cotton cloth? What the hell was that? What did it have to do with whether it would explode or not?

Soon, the expressions on everyone's faces changed from confusion to surprise.

For nothing else.

Instead, the flame on Zhang Yuqing's right hand licked the small piece of cotton cloth in his left hand, but the cotton cloth miraculously did not burn!

Who doesn't know that fabrics like cotton, linen and silk can easily catch fire?

The situation in front of me.

It simply goes against their inherent rules...

Everyone's eyes widened in amazement. "This... this didn't catch fire? How is that possible? What kind of trick is this!?"

Zhu Yunhuan, who was standing aside, had his eyes slightly lit up.

The corresponding word immediately appeared in my mind: "Flame retardant cotton!"

The chemical industry has flourished in later generations and is widely used in various fields of society, large and small. "Flame retardant cotton" is one of them.

By chemically treating some materials, their properties are changed.

It is similar to the impregnated matchlock used on the matchlock gun, but the impregnation process of this flame retardant cotton seems to be much more complicated than that of the matchlock.

Zhu Yunhuan was not very clear about the specific details.

Looking at Zhang Yuqing holding the cotton cloth that remained unburned after being licked by the flames, Zhu Yunhuan was secretly delighted. "After the initial foundational guidance, the Ming Dynasty's technology tree has begun to quietly sprout and grow!"

"Disciple sees no surprise in His Majesty's eyes. I guess... Your Majesty really understands what's going on!" Ma Rui, who was standing behind Zhang Yuqing, had been secretly observing the changes in Zhu Yunhuan's expression. Seeing that Zhu Yunhuan still had a plan in mind, he immediately said excitedly.

The other people also had a look of "as expected" on their faces.

Zhu Yunhuan didn't know why they reacted like this. Logically, shouldn't they start introducing their products like they were presenting treasures?

After all, they have even produced this finished product - unburnable cotton cloth - and in the future they can apply the finished product to practical fields, such as equipping researchers like Feng Xu and Lin Yishan who are exposed to danger, or even equipping musketeers on the battlefield to prevent damage caused by dangers such as barrel explosion and accidental discharge... These will be of great benefit.

Zhu Yunhuan nodded secretly, affirming their achievement: "Well, it's a good thing, and it will be very useful in the future. With this thing, who knows, the explosion just now might not hurt anyone."

Others nearby also reacted.

Suddenly, he said, "Yes! The Taoist priests really have a way! If we can use this kind of fabric to make clothes... the benefits will be huge!"

"In the past, those muskets were prone to exploding, and many of our brothers died in vain. If we had this good thing back then, those brothers would have had a chance to survive, if not survived completely!"

"Hmm! Good stuff! Really good stuff!"

"..."

Of course, this group of people would be happy to see something like this. In fact, they themselves could benefit from it right now. After all, they deal with dangerous items like gunpowder every day.

However, looking at the excitement of the crowd.

Zhang Yuqing, Ma Rui, Liu Yuanran, and Yuan Gong all showed a hint of embarrassment on their faces, as if they were a little embarrassed.

Zhu Yunhuan also noticed it quickly.

He immediately asked, "I see that you four still have doubts in your hearts?"

The four of them nodded immediately, looking at each other, as if trying to figure out who should talk about this with their eyes.

After a pause, Zhang Yuqing simply said:

"To answer your Majesty, this unburnable cotton cloth... is actually something we found by chance. We only remember that it accidentally fell into the diammonium phosphate solution. After it was discovered, we fished it out and dried it, and it became what it is now. But when we tried to make it again, it didn't work..."

"Just now, we disciples heard that Your Majesty had arrived, and hurried here. We wanted to ask Your Majesty for advice on this matter, and hoped that Your Majesty would give us some guidance..."

Their words, filled with technical terms, made it difficult for others to understand.

After hearing this, Zhu Yunxun showed a serious look of contemplation...
