Since the last time he saw Cui Jiu's old thief, Yang Chuan's attitude towards his cousin's father has always been lukewarm, and he will leave immediately.

For this reason, this Hun man was very sad, and knelt on one knee several times, holding the 'cattle slaughtering knife' that Yang Chuan gave him, and wanted to cut a few times on his face, so as to inform the Tengger Tian in his heart: to Yang Chuan, he is loyal and will never betray.

Yang Chuan decided to have a good talk with this Huns.

"Uncle Tangyi, are you an embroidered messenger?"

"It's not."

"How did Cui Jiu know about those things in Mobei last time?"

"I told him."

"Why?"

"Cui Jiu said that he just wants to hear the truth, and he will definitely not embarrass Xiao Langjun."

“……”

Some words are said, but in fact, they are not farts, and Tangyi's father frankly admitted that those bad things in the land of Mobei were all told to Cui Jiu, and the mustard in Yang Chuan's heart was naturally unraveled.

However, it also reminded him that from now on, all important and secret things must be done by him alone, and no one else must be involved.

Huo Quai's illness is not good.

For example, if he wants to dig three emergency passages between Zhuangyuan and the northern foot of the Qinling Mountains, he can only do it alone......

……

In June of the wheat yellow, Guanzhong is a big oven, and many birds and beasts are so hot that they have fled into the depths of the Qinling Mountains to escape the heat.

Sister Leopard is also too hot, hanging a pink tongue more than a foot long all day long, but she is unwilling to leave Yang Chuan to act alone, and she plays with water in Jinghu all day long.

Yang Chuan was also too hot, but when he remembered that he was almost captured by the veterans sent by Princess Guantao last time, he didn't dare to leave the village easily, so he had to start trying to build an ice warehouse in the village.

The technology of saltpeter ice making is basically common knowledge in later generations, but in the Han Empire two thousand years ago, it was too shocking, and if you don't get it right, you will cause you great trouble.

Therefore, after thinking about it, Yang Chuan finally decided to sell the 'invention right' to Cao Xiang.

This guy is the great-great-grandson of Cao Shen, the founder of the Han Dynasty, the hereditary Marquis of Pingyang, his uncle is the emperor Liu Che, and his mother is the eldest princess of the Han Dynasty.

Cao Xiang said, no matter if it is a good reputation or a bad reputation, as long as Yang Chuan finds it useful, it will all be on his head, and you are welcome.

"Cao Xiang, I have found a strange phenomenon in the Western Regions, you are well-informed, come and help me refer to the details, I want to get us a big ice storage." While fishing on this day, Yang Chuan said suddenly.

"What phenomenon? The Great Icehouse? ”

Cao Xiang really went up, patted his chest and said, "Don't worry, as long as you can make a big ice warehouse, I will send you twelve more dancers...... Ahem, Cook Lady. ”

Yang Chuan ignored this guy's nonsense, but directly took over two clay pots, one large and one small, and filled them with water respectively.

Then, he put the small pot in the big pot, pinched a large bag of saltpeter powder in his hand, and said with a smile: "I once saw a strange ice spring, which is roughly like this, and guess what?" ”

Cao Xiang shook his head directly and said, "I can't guess." ”

"Yang Chuan, how much money do you need Just ask, Ben Hou doesn't care, as long as there is a good way to make a piece of ice in the summer, I can earn millions of dollars in Chang'an City in just one month."

Yang Chuan sighed, laughed and cursed the 'evil old society', and poured saltpeter powder into the large basin of water.

Almost visible to the naked eye, the water temperature of the small basin cooled down rapidly.

Because of the large amount of saltpeter, after about an hour, the water in the small basin was completely frozen, and the fingers touched it cold, cold, and a layer of white mist filled the hot air.

Cao Xiang explored it very carefully, and finally determined that the thing that Yang Chuan came out of was indeed a real ice cube, and this guy couldn't help but be ecstatic, looking up to the sky and laughing: "Hahaha, Benhou is really a genius of the Han Dynasty." ”

Then, this unique craft of 'ice making in the cool summer' naturally became the 'patent' of Pingyang Hou Cao Xiang: "Yang Chuan, Ben Hou thought about it, it's too cheesy to send you gold directly, or ...... I'd better send you a dozen dancers, right? ”

Yang Chuan said expressionlessly: "I like cheesy things. ”

For Yang Chuan's greed for money and not being lustful, Cao Xiang despised it to the extreme, and scolded: "Okay, good, I haven't seen a person like you who is greedy for money, and when you turn around, you will send fifteen catties of gold......

……

Princess Pingyang came to Yang Chuan's fiefdom early the next morning, and when they met, she threw fifteen catties of gold to Yang Chuan with her own hands: "The art of making ice in the scorching heat is now the unique secret method of the Pingyang Hou Cao family, and it is no problem for you to build an ice warehouse by yourself, but you are not allowed to pass it on." ”

Yang Chuan is full of promises.

In a way, the wealthy families of the Han Empire are actually predators who eat people and do not spit out bones, and each famous family has their own way of making money.

For example, Cao Xiang's family, there are several salt farms with amazing scale on the coast of the East China Sea, and nearly half of the green salt trade in the Han Empire is operated by Princess Pingyang and Cao Xiang.

"Yang Chuan, you are very good."

After completing a business, Princess Pingyang carefully checked her son's body and found that the 'diet therapy method' during this period had excellent results, and she was naturally in a good mood: "I heard that your cooking skills are good, so this palace will stay in your Zhuangzi for a few days and try your skills." ”

When she said these words, Princess Pingyang had a look of appreciation, as if her eating and drinking was a kind of grace to Yang Chuan.

Of course, for Yang Chuan, these details are not important.

He arched his hand and smiled: "The eldest princess can escape the summer in the village, the kid is overjoyed, it just happens that the new wheat is ripe, the kid will let people grind noodles, and eat a bowl of slurry water to cool off today." ”

Princess Pingyang asked curiously, "Slurry water surface?" ”

Yang Chuan said with a smile: "It is a kind of food for the common people, which is sour and pleasant, clears away heat and heat, and can solve a lot of heat poison, viciousness, drug poison and lead poison; Don't hide it from the eldest princess, in addition to milk, shrimp, kelp and other food, this slurry water also plays a big role. ”

Princess Pingyang nodded slightly: "Okay, I'll taste your slurry water today." ”

The preparation of slurry water is very simple, that is, fresh vegetables are blanched in a pot of boiling water, nested in a large vat together with batter water or noodle soup without salt, and naturally fermented for three or five days, until the soup is transparent and clear, sweet and pantothenic, it is an excellent food raw material.

Of course, in the later generations of Tianshui, Longxi, Guanzhong, it is still an excellent, pure natural drink, suitable for all ages, cheap and good.

As early as two months ago, Yang Chuan nested several large vats of slurry water, which were small celery-flavored, sunflower-flavored, alfalfa-flavored and bitter and bitter vegetable flavored, each with its own merits.

For example, this celery flavor, the emphasis is on a refreshing and delicious, hot weather, drink a big bowl of choked green onions, peppercorns, sesame oil slurry water, full of aftertaste, enough to keep all day.

Among them, the most delicious is still the slurry water that comes out of the bitter and bitter vegetable nest.

Bitter bitter herb is a good wild vegetable, a bit like dandelion, however, its leaf surface is slightly narrower, bitter taste, from the slurry water tank, only need to sprinkle a little sesame oil, salt, is an excellent cold dish.

In the evening, the sun was skewed, but it was still unbelievably hot.

On the roof of a tall wooden building, Princess Pingyang knelt in the center, looking at a small bowl of slurry water, four kinds of cold salad and a large plate of fried lamb tripe placed on the table in front of her, her face was a little ugly.

This Yang Chuan is really too eyeless.

gave her a big princess, and prepared such a vulgar and simple food?

It seems like a good smell of food, but visually, it's too vulgar, right?

Especially the four kinds of cold vegetables, which are clearly the wild vegetable dumplings used by poor families to feed their stomachs, what bitter vegetables, alfalfa vegetables, small celery, and small cabbage......

"Yang Chuan, the alfalfa grass that Zhang Qian brought from the Western Regions seems to be forage for livestock, right?"

Princess Pingyang held back her anger and said very coldly: "You use such vulgar vegetables to entertain nobles? ”
