Datang: Combining the dual combat power of Lu Bu and Xiang Yu at the beginning

"Nitroglycerin"?

Li Zhiyun's question instantly attracted everyone's attention.

"Emperor Qiyu, what is nitroglycerin and what is it for?"

Yuan Tiangang's eyes were full of surprise, Li Zhiyun had already brought him too many surprises, and this time, it seemed to be even more powerful!

Li Zhiyun did not intend to tell them the so-called scientific truth, because it was thousands of years later.

"Chief Yuan, do you have lard and caustic soda here?"

Everyone was stunned, what do you want lard for?

Could it be that the emperor is hungry and wants to start cooking?

And after cooking, you have to wash the dishes with caustic soda?

Although Yuan Tiangang had doubts, he immediately arranged for the Taoist priest to bring a pot of lard and caustic soda.

Under everyone's expectations, Li Zhiyun ordered people to put lard into the iron pot, and then added water and caustic soda!

Dizzy!

Everyone has never seen this kind of tumultuous operation, what the hell is this for?

"Everyone is optimistic!" Li Zhiyun said as he picked up an iron rod and began to stir it:

"I'm boiling glycerin now, and I need to stir differently when boiling, not fierce fire, but medium fire!"

Everyone was staring at the pot with bated breath.

After a while, Li Zhiyun stopped:

"You can stop if you stay up to this viscous state, and the next step is to cool down!"

Liu Min asked thoughtfully,

"Emperor, this seems to be similar to the previous boiled sugar!"

Li Zhiyun nodded, but his tone became serious:

"It's about the same, but the next step is particularly dangerous!"

Dangerous?

Everyone immediately happy, add water to the oil pan, can it not be fucking dangerous?

Not often.

"Wow, everyone, look at it, it's changed, it's changed!"

Liu Min, who was carefully observing, immediately roared!

Everyone pouted their asses and looked inside the pot.

I saw that stratification began to appear in the pot!

The bottom part is a white solid, and the top part is liquid!

Li Zhiyun poured the liquid into an empty wine jar, and then dug out the white solid.

"Look, this is glycerin!"

Everyone sniffed around the wine jar.

"Emperor, this liquid is glycerin, so what is this white?"

Li Zhiyun smiled and turned around to pick some wildflowers around him, rubbed them, and mixed them with this white thing.

Instantly, a faint fragrance came to my face.

Li Zhiyun handed it to Poppy and said softly:

"This ah, it's called soap!" You can wash your face and take a bath, you try it first? Poppy

was flattered, and although she was a little puzzled, she still chose to believe Li Zhiyun for the first time.

Then, Poppy brought a basin and, under the guidance of Li Zhiyun, began to wash her face.

And the next moment.

When Poppy raised her handsome face, everyone was suffocated!

I saw that Poppy's face seemed to be more clean, and every pore was stretched!

Poppy was even more surprised, she could really feel that her face was breathing happily!

It was a particularly wonderful feeling.

And when Poppy looked down at the water in the basin, she became a little shy.

In the past, when I washed my face, the water was still the same water, but now the water in the basin seems to be a little muddy!

Could it be that this "soap" can also remove foreign bodies from the face?

Everyone was eager to try, but they were snatched by the quick-eyed Bing Yuanzhen.

He immediately brought a basin of water and slapped the soap on his face.

"Wow, cool! So refreshing!

When Bing Yuanzhen raised his head and raised his face, everyone was also stunned!

A big old rough and dark face turned out to be a lot whiter and tender!

Look down again at the water in the basin.

Oh yes!

It's all fucking black!

"Haha-

" Everyone immediately laughed, and Poppy further said:

"Emperor, this soap will definitely become the favorite of the noble ladies of the major cities and counties, even if a piece is sold for ten taels of gold, it must be robbed!"

Everyone's eyes lit up immediately, and before they knew it, Li Zhiyun had easily invented firecrackers and soap!

If you get this emperor, how can you ask for it!

Li Zhiyun looked at Poppy with a smile, and really didn't see that this little woman was born to be good material for business!

Well... If you can, then you can be a minister of commerce in the future!

Changsun Wuji quietly took advantage of everyone's conversation and laughter, suddenly reached out and grabbed a handful of soap and put it in his sleeve bag.

Well... Bring some to your sister, and your sister will love it!

Just when everyone thought it would be over here, Li Zhiyun spoke again: "

Yuan DaoChang, may I ask if you have sulfuric acid here?"

Yuan Tiangang was suddenly stunned.

Sulphuric acid?

I've never heard of it!

"Emperor Qiyu, are you asking nitric acid? There is some nitric acid!

Li Zhiyun shook his head, and suddenly remembered that the "sulfuric acid" of this era was not called "sulfuric acid".

"Sulfuric acid is alum!"

Only then did Yuan Tiangang react, and immediately ordered someone to bring a jar of nitric acid and green alum.

Li Zhiyun quietly put on the golden soft hog armor rewarded by the system, and put the three jars containing glycerin, nitric acid, and sulfuric acid together, and said to everyone:

"Please stay away from me, the following operation will be dangerous!"
