Chapter 88

Thanks to the early years of the Tang Dynasty when Li forgets to worry, he can show off with this saltpeter ice.

It would be well known if he crossed in later years. During the Tang and Song Dynasties, people had discovered that putting saltpeter into water would freeze the water.

However, in the second year of Zhenguan, Li forgets to worry that saltpeter can make ice, but no one believes it.

Not to mention that Niu Wu and the old Taoist don't believe it, even Li Heng and Peilan shake their heads. Only the beautiful boss covers his mouth and laughs.

Although Su Changqing is a liberal arts student, she has studied basic chemistry. The scientific name of saltpeter is potassium nitrate. When it is dissolved in water, it absorbs heat and freezes the water when the temperature decreases.

Li forgot to worry. Seeing that several people didn't believe it, he didn't say much. He asked pelan to get a big wooden basin and a small barrel basin.

Pour water into the wooden basin, saltpeter into the wooden basin, and pour water into the copper basin and put it in the wooden basin.

Soon, in the surprised eyes of the Taoist priest, the water in the wooden basin began to freeze slowly, and then the water in the copper basin began to freeze slowly

"This, what spell is this!" Niu Wu stared at the ice in the basin.

The old housekeeper's knee almost softened again. Fortunately, Li forgot to worry and helped him: "Li Heng, what are you doing?"

"Lang, Lang Jun, have you become an immortal? Light water into ice. This, this is an immortal method!"

The little girl Peilan was no better than Li Heng. She covered her mouth and stared at her black eyes. She also couldn't believe her eyes.

Only the old Taoist priest, after being surprised for a while, began to think about the truth. He also touched the ice in the wooden basin and tried the temperature.

"Wuliang Tianzun, it turns out that saltpeter can freeze water. I understand." the old Taoist priest checked the head and whispered a Taoist sign.

Li forgot to worry, slightly surprised, looked at the old way, and then suddenly.

These Taoists in China can be said to be the first batch of chemists in China. Even gunpowder was made by these Taoists when they were refining pills. It's not surprising that they have some preliminary chemical knowledge.

However, in Li's opinion, these Taoists are not so much chemists as a group of "terrorists". They indiscriminately refine some messy things all day and deceive others to eat. It's really immoral.

Li Qieyou dares to swear that if anyone dares to give him a pill refined with mercury, lead, sulfur and dansha, he will definitely dare to kill with a knife!

These "terrorists" have amazing imagination and people have to be convinced!

At the time of incense, the two pots of water formed ice under the attention of the people.

Li Qieyou took out the copper basin, asked Niu Wu to chisel the ice in the wooden basin with a knife, wrapped it with a towel, and stuffed it under Niu Yong's armpits, inner thighs and forehead to cool down.

After eating cephalosporin, Niu Yong had ice to cool down. His originally rapid breathing soon calmed down.

The old Taoist priest took his hand and held his pulse. He was very surprised: "the pulse is stable and powerful. Grandpa has really improved. It seems that he is worried about asexual life. What medicine did you give grandpa? It has such magical effect?"

What medicine did you take? Cefaclor capsule, Datang only this box!

Li forgot to worry naturally can not answer like this, can only smile mysteriously: "divine medicine, antibiotics! Unfortunately, only these, there will be no second box in a thousand years."

He shook the plate of cephalosporin capsule at the old Taoist priest and Niu Wu.

There are only 27 cephalosporin capsules in a box. Take one capsule three times a day for three days.

In other words, this box of cephalosporin can only eat three courses of treatment, and it has been out of print since then.

Take out nine cephalosporins to save Niu Yong's life. Li forget worry won't hurt at all. He thinks it's worth it. Compared with Niu Yong's life, his own pay is not worth mentioning.

His words surprised Niu Wu. Niu Wu didn't expect Li forgetful to take out such valuable drugs in order to save his brother.

"Xiao Lang, i... you..." Niu Wu, an eight foot man, didn't know what to say at this time. He just knelt down to Li forgetful sorrow and banged his head.

His reaction startled Li QIAOYOU and hurriedly stretched out his hand to pull Niu Wu.

But Li forgets to worry that his small physique can't hold Niu Wu. He can only be hurt by Niu Wu's heavy gift.

"Erlang, what are you doing? Do I want you to save Dalang?" Li forgets nothing and turns his eyes.

Why do people in Datang like to kneel down so much? They can't stand it!

"Xiao Lang, it should be. If I don't kowtow to you, big brother will kill me when he wakes up." Niu Wu replied in a voice.

“……”

Niu Yong's crisis has been lifted, and everyone is in a good mood now. The original dignified atmosphere in the Pianfang has eased a lot.

Su Changqing looked at the small copper basin in Li forgetful's hand: "forgetful, just use one basin for ice making. What's the use of another copper basin?"

"Hey, hey, there is saltpeter in the ice in the wooden basin, which can't be used for eating. It can only cool Niu Dalang's body. The ice in the copper basin can be eaten. Do you want to eat ice cream?" Li forgets to worry and laughs with the copper basin.

Su Changqing's eyes lit up when he heard the speech: "ice cream? Can you make it?"

"Hey, hey, try it. It should taste good."

When Li was a child, he didn't have any ice cream in the countryside, but they also have a way to make local ice cream, which is actually smoothie.

Use a plane to make ice cubes into smoothies, then add sugar water, milk and fruit to stir, and you can make delicious smoothies.

There is no shortage of fruits at home. Many villagers will send them some fruits when they pick them on the mountain. Back against Shouyang mountain, there are different wild fruits to pick all year round.

As for milk, it's simpler. There are many in your kitchen.

These milk are raised in farmers' homes and produced by cows in farm cattle. Su Changqing had already agreed with the farmers that the milk squeezed out every day would be sent to their home.

Don't think that only later Dutch black-and-white cows can produce milk. In fact, yellow cattle produce milk, but the output is not so much.

In fact, drinking milk has become very popular in the Tang Dynasty. On the murals of later Mogao Grottoes, there are many pictures of peasant women milking.

During the Tang and Song Dynasties, many celebrities liked to drink milk, including Bai Juyi, who were all milk lovers.

Plan the smoothie, stir the milk, fruit and sugar water, mix well, and the first smoothie of Datang will be ready.

Li forgot to worry and asked pelan to prepare a small bowl for everyone.

Although it is early spring and February and the weather is still a little cold, no one refuses such a delicious and attractive smoothie.

Even Niu Wu temporarily put down his worries about his brother and drank the bowl of smoothie.

"Happy! Xiao Lang, you smoothie is really happy!"

The old Taoist priest was also very interested in smoothie and nodded repeatedly.

When the people finished eating, the little girl Peilan took away the dishes and chopsticks. Li forgot to worry before he saluted the old Taoist.

"Dare you ask the long honor?"

"Poor Sun Simiao."
