Regarding the road of jade silk, this is calculated until 2,000 BC, compared to the Qin State at this time, 1,800 years ago.

Then it was intermittent and finally disappeared during the Spring and Autumn Struggle.

(The Jade Silk Road is not nonsense, it does have a historical basis, and it is safe to say that the Jade Silk Road is the predecessor of the Silk Road.) ）

King Qin couldn't figure it out, and Bai Qi couldn't explain it clearly.

However, King Qin is an optimist, and since he can't figure it out, he doesn't want to. King Qin said to Bai Qi: "Brother Wei heard that there is a BMW in the Western Regions, and Bai Hui named it Khan Blood BMW. If there is, you will be the first one. ”

"Thank you, the king."

The generals who don't love horses, and the horses that can be admired by Bai Hui must not be ordinary horses.

As for the first horse for himself and not for the king of Qin, this question was not so complicated in vain, the Qin State was not the era when the Son of Heaven was the supreme in later generations, and the relationship between the king and the minister was much better.

Suddenly, the smile on King Qin's face disappeared.

"Your Majesty!"

King Qin waved his hand at Bai Qi and said in a low voice: "You say, the six kings of these countries ......"

When King Qin mentioned this, Bai Qi was also silent.

The six kings of the world, except for the king of Yan, it can be said that the death of each king is related to Bai Hui, if it is really related, the death of the king of Song is also somewhat related to Bai Hui, and then Zhao died two kings because of Bai Hui.

If the countries knew about this, they would not immediately carry out a joint attack on Qin.

King Qin and Bai Qi shut up at the same time, no one continued to talk about this topic, and it felt terrible to think about it.

Two days later, Bai Qi moved to defend the river meander, and King Qin and Bai Hui were invited by Gongzi Sheng to Handan.

Before leaving, Bai Qi and Bai Hui took advantage of the time when King Qin and Gongzi Sheng were chatting nonsense, locked up and discussed secretly for half an hour, and then the convoy officially set off.

At this time, it is the height of summer, the avenue is not a path, and there are not many shady places.

King Qin was wearing only a light silk robe, opened all the curtains of the carriage, and held a pu fan to fan non-stop.

At a big bend in the road, King Qin found through the window that Bai Hui's carriage had its curtains closed.

Eccentric!

The sun was setting in the west, and the front team had found a suitable camp and set up camp. Half an hour later, the convoy of King Qin, Bai Hui, and Gongzisheng settled in the camp.

King Qin first dressed neatly, and then got out of the carriage, no matter how hot it was, the king's majesty must not be less.

But after a while, King Qin felt that the clothes on his back were completely wet with his own sweat.

I saw more than a dozen Qin army logistics soldiers carrying a rattan box every two people to all the soldiers who entered the camp, and after opening the rattan box, there was a lid, and the lid opened to be a thick cover of asbestos cloth filled with grass, and then opened a thin wooden plank, and then a layer of linen.

One by one, the white, steaming sticks were handed to the hands of the Qin soldiers.

King Qin could see clearly that every Qin soldier had a happy look on his face.

At this time, Bai Hui got out of the car.

Bai Hui is the opposite of King Qin, who got out of the car and was dressed neatly, while Bai Hui threw the one he put on the outside on the car, wearing a linen shirt without sleeves, and on his leg was a pair of knee-length pants that were a little longer than the beach pants of later generations, and a pair of straw flip-flops on his feet.

Dress is a rite.

Bai Hui's dress is even more embarrassing than the old farmers in the mountainous areas of Qinguo.

Between image and coolness, Bai Hui chose the latter.

Wrong!

Did Bai Hui get out of the car and take off his coat?

King Qin strode to Bai Hui's carriage, and as soon as he pulled the curtain, a coolness came from inside the carriage.

"Bai Hui, you explain to Brother Wei clearly, what's going on."

"That ......" Bai Hui grabbed a short hair, looked up at the sky, and then said: "Brother Wang, there is a great sage who said that as a courtier, he gives gifts to the king, this is called Mei Jun, and it is a bad minister......

Seeing King Qin's face as black as the bottom of a pot, Bai Hui had no choice but to say: "This was thought of temporarily before leaving, but I forgot that Brother Wang was also there." ”

"Tomorrow we will leave and change carriages." King Qin threw down these words and walked straight to the camp.

Bai Hui trotted a few steps to follow: "Brother Wang, don't you want to be cool at night." ”

"Oh?" King Qin turned his head to look at Bai Hui.

Bai Hui clapped his hands, and immediately a small school ran up to the front and bowed down to listen to the order.

"The tent for the king is ready."

"Alright. I also added the ice basin, and prepared the freezing point. "The people in the logistics battalion are not heartless like Bai Hui, and they don't need Bai Hui to tell them to think of King Qin first.

Of course, this credit fell on Bai Hui's head, at least King Qin thought that Bai Hui ordered it.

In fact, Bai Hui didn't think about anything.

This ice was only obtained occasionally, and Bai Hui originally wanted to try to make a big killing weapon, but unfortunately Bai Hui hadn't read a book like the Crossing Book before he crossed over, so he couldn't make this big killing weapon.

When he walked to the tent where he was resting, the king of Qin found that the soldiers of the Qin army were eating ice.

Eat ice !? in the summer

King Qin felt that his worldview had been turned upside down.

Outside the tent, it was the height of summer, and people who were hot wanted to take off even a layer of skin. Inside the tent, there was a slight coolness, like autumn.

A bowl of dry boiled water with longan, coupled with the original version of ice cream with milk, made King Qin's dissatisfaction with Bai Hui disappear without a trace in an instant.

"Bai Hui, what kind of spell is this?"

"Brother Wang, you can't even be warm in winter and cool in summer, how can you be called a nobleman, this is the secret technique of the Qin Palace, Xia Bing!"

The secret technique of the Qin Palace, the King of Qin has been the King of Qin in the Qin Palace for more than ten years, and he will not know what secret techniques the Qin Palace has. With a black face, he took a big mouthful of milk ice in his mouth and asked, "Talking about people." ”

"Okay, this is Dahewei's camp, Dahewei had a little skirmish with the Xiqiang people in Qiang Road, and then made friends with the Xiqiang people with semi-porcelain, and then found a mine in the Qiang land, the real nitrate mine."

King Qin thought about it and nodded silently, it seemed that there was this report, but no one cared.

Nitrate can be used in medicine, and it has been one of the important medicinal materials hundreds of years ago.

The real nitrate is saltpeter, and the false nitrate is miscanthus nitrate. The Qin people already had some primitive ways of distinguishing them, but the medicinal value of the two was similar.

(Qiang Dao: The approximate location is the later Danchang)

Bai Hui didn't mention his big killer because he didn't know the recipe or how to make it.

I only know the approximate, that is, saltpeter, sulfur, charcoal, and that's it.

But Bai Hui knew that saltpeter could make ice with zero difficulty and could be used repeatedly.

"Then, I can borrow saltpeter to make ice. Especially in the summer, saltpeter can be used again and again after making ice and then drying it. So it's just a little bit of labor. ”

"Very good."

Qin Wangxin said that Bai Hui would really enjoy it, and another person would never be able to say such a thing as warm in winter and cool in summer.
