Ps: It's a little thing, my father-in-law has a hernia, I need a small operation, I took him for a check-up today, and I was admitted to the hospital tomorrow, and I have to go to the horse without a son and son-in-law, so there are fewer updates. Rest assured, this is not an excuse to make excuses, and it will not be interrupted, even during my father-in-law's hospitalization, I will try to maintain two shifts a day, and never keep changing.

There is not only the sea of grass on the Longdong Plateau, there are also inner lakes and rivers, hilly cultivated land, there is a river three zhang wide outside the city of drinking horses, the east and west directions, it is the tributary of the Kutu River, there is a kind of barracuda with a sharp head and a sharp tail in the river, it is said that the most love to swallow the horse manure of the Yiqu people, the taste is incomparably delicious. When the army was stationed in Drinking Horse City, the young officer Gongzi and Nie Zhu were not less caught and eaten, but Bai Dong resolutely refused to eat it, and he was disgusted when he thought of eating horse manure, and he couldn't vomit.

Five hundred cavalrymen were selected from the old army of Yongdu to closely escort hundreds of carriages and marched all the way to the northwest. These old soldiers are just like the Yiqu people, all of them are men who have grown up on horseback since childhood, no stirrups and no saddles to borrow power, but they can clamp the horse's belly with their legs, bow and shoot hundreds of shots, everyone has a bronze sword, relying on horsepower to collide, even if they don't use wrist power, they can also behead people, they are the first-class elite of Lao Qin, only under the 'light service battalion' that Yingqu Liang once commanded.

Bai Dong had already given the order, and the team marched along the river, guarding all the way, without the slightest carelessness. Yingquliang had never seen him so nervous, and the young officer Gongzi was even more curious, didn't it already show it in the letter analyzed by Jing Jian? There is no Yiqu garrison in this direction, and even the shepherds are difficult to meet, and they don't know what his brother is nervous about, and he was also in the military tent in a daze that day, listening to the analysis of the military situation, and then the flying eagle passed the book. A boy named Mo Xian, the public loser, actually touched the location of Mu Zhongtu, the new king of Yiqu. At that time, the Jing Jian read it out loud. Where Mu Zhongtu was, the cattle and sheep were like clouds, the soldiers were like rain, and there were as many as 20 flags with wild goose feathers tied to the top!

Twenty wild goose flags means that there are 20,000 elites; Bai Dong guessed correctly, Mu Zhongtu was too insidious, and the real elites were left by him on the Longdong Plateau, with the purpose of destroying the Qin army in one fell swoop.

When the letter was confirmed, the fungus burst out laughing. For a while, because he found the location of Mu Zhongtu, it was indeed one of the several locations that Bai Dong had guessed before; The second is that the block in the chest is gone, this time Qin Wei is a coalition army, and it is also a secret competition, Pang Juan's letter of sealing the war report made him infinitely depressed, and he almost doubted himself, now it seems that it is not how powerful Pang Juan is, what is a great victory all the way, it turns out that what he encountered is just some third-rate miscellaneous soldiers of Yiqu, and the real decisive battle to capture the king depends on your grandfather!

Didn't you say that after deciding on Mu Zhongtu's position, you would think about a strategy to destroy the enemy? Young Officer Gongzi is gearing up every day. Waiting for the final decisive battle, even Yingqu Liang was guessing what kind of clever plan Bai Dong would come up with to gather the elite of Yiqu. As a result, Bai Dong asked for an elite soldier and a hundred carriages, saying that he wanted to go west to find the 'Wuzhuwu Valley' mentioned by the ink line, which was what Lao Qin needed most, and it was related to the success or failure of this battle.

This time, he was able to find the Yiqu ambush and determine the location of Mu Zhongtu, relying on the 'intelligence system' that was more advanced than the opponent's, so Bai Dong would not be careless, although the army was all Qin people, there should be no problems, but there is an exception to everything, in case something happens. Qin traitor's or something is not very good, and the ink line has only walked through this place, heard some legends, and the description is not very clear, whether there is anything they need, and they will not know until they arrive, so they have never said anything about the fungus change, which makes the old guy's heart itch, and it is estimated that it will not be much better than the little daughter-in-law who is leaning on the door.

"I have traveled all over the world, and I have also been to Longdong. Although I have never been to the Uzhiwu Valley, I have heard the legend about this valley, this is a Devil's Valley! No one in Yiqu dares to approach, are you sure you want to go? ”

Wu is the meaning of 'devil' in Yiqu language, although Nie Zhu is bold, he has never been there back then.

"The devil? Perhaps there is the most miraculous thing there, more lovely than the messenger sent by heaven? ”

Bai Dong just smiled, the stones in the Wuwu Valley would inexplicably emit fire, and when lightning was shot down, it would make a deafening sound, and the Yiqu people would think that this was the power of the devil, but he hoped that this 'devil' really existed.

***

Wu on the Wu valley really has some devil valley momentum, the valley mouth mountain wind whistling, like a wolf howling, no grass in the valley, snakes and insects extinct, from a distance, the mountain wall and the roots are gray-white, occasionally there are cracks falling from the mountain wall, it will bring a thunderbolt fire. Human beings will always have a sense of awe for natural phenomena beyond the scope of their own knowledge, even ruthless people like Nie Zhu can not be an exception, the faces of the first few Yongdu old soldiers to enter the valley are white, if it weren't for the ruthless military law, these men who kill people on the battlefield without blinking an eye will turn around and flee for their lives!

"Outside the camping valley, load these stones into the wagon, as fast as possible!"

Bai Dong entered the valley first, and when he saw the gray-white crystalline stones piled up like a hill in the valley, he couldn't help but want to laugh out loud, saltpeter! With this thing, it's all about it!

Seeing that the main general took the lead in entering the valley, the two sons also followed, and the old army had to bite the bullet? According to Bai Dong's instructions, he handled these strange stones with care, and loaded them into the carriage, which soon filled more than a hundred carts.

It's getting late, and I can't go back today, Bai Dong smiled and looked at Yingquliang and Gongzi Shaoguan: "Second brother, young officer brother, are you hot?" ”

"How can it not be hot, Brother Bai? I'm even getting my ass wet. ”

The Longdong campaign has been more than a month, and now it is the hottest weather in Zhongfu, people will sweat if they don't move, let alone move stones, and the young officer of Gongzi has a lot of complaints: "Brother, these stones are not golden bumps, what is there to move?" You used 500 elite soldiers and hundreds of wagons just to get these stones back? There are a lot of stones in the city, why do we have to run so far? ”

Don't talk about him, Yingquliang can't figure it out. However, he would not complain like the young officer of Gongzi, he just looked at Bai Dong suspiciously, waiting for his explanation.

"Well, I like the way the stone looks, so it's not too much to get some back, right? By the way, the fighters have worked hard, and we need to treat everyone tonight. It's so hot. I can't say I'm going to do it tonight. The flat ground conjured up some swallow and black ice, do you remember the iced sour plum soup? ”

"Iced sour plum soup, brother, you're not joking, are you?"

Don't say that it is a foodie like Gongzi Shaoguan, and the sound of swallowing saliva also came from Yingquliang's throat, this hot weather, and he just sweated all over, if he could have a bowl of iced sour plum soup, he couldn't think about it, it was too gluttonous. The sound of swallowing saliva passed down the Qin army column, almost overpowering the whistling mountain wind. Faced with the temptation of sour plum soup, who is in the mood to ask Bai Dong what he wants these stones for?

Even though it was night, it was still very hot, but there was a faint hint of coolness in Bai Dong's big tent.

A large wooden basin was placed in the center of the military tent, which was used to wash and wrap wounds in the wounded camp, this was newly made and had not been used, and was asked by Bai Dong, and the basin was full of clear water, and three bronze tripods were placed in the water. It is about the same size as a big old bowl, and the body is just at the same level as the water level. The water did not come in, and the body never rose above the water.

Yingqu Liang, Gongzi Shaoguan and Nie Zhu looked at the wooden basin in amazement, and couldn't say a complete sentence for a long time. It's hot and you want to go bare-bottomed, and no matter how much water you drink, you can't quench your thirst, but the water in this wooden basin is slowly freezing!

That's right, it's icing, and streams of cold air are rising from the wooden basin, rushing to the face, so cool and comfortable!

The eyes of the three of them were fixed on the three small bronze tripods, there was also water in the tripods, and there were no other rare things in the water, that is, they soaked in those strange stones taken during the day, and reached out to try it on the top of the copper tripod, and sure enough, it was even colder here! The young officer was too curious, and walked around the wooden basin a few times, enjoying the rare coolness, while reaching out to touch the copper tripod, but was pushed away by Bai Dong: "Do you want your hand?" It's going to get frostbitten! ”

"Ping An Lang, are you a human or a fairy? This, this"

Nie Zhu looked at Bai Dong, his body trembled slightly, he actually wanted to kill such a person?

Calm and calm like a canal beam, his complexion has changed greatly at this moment. Summer conjured up ice out of thin air, and it wasn't from the ice cellar deep underground like the nobles of Yandi did, which was beyond his comprehension.

"I'm a living person, I'll be hungry if I don't have anything to eat, and I'll have to take medicine when I'm sick, don't treat me as an outlier, don't. Lao Qin just treats me as a stranger, and always likes to test my medicine, and it turns out that my mouth will be swollen as well."

asked Yingquliang and Gongzi Shaoguan to come and see the process of making ice by themselves, but they didn't want to hide it from them; This is different from the invention of pen, ink, paper and inkstone, this is the flat ground to pick the cake and turn ice in summer, it is already a miracle of dry creation, if you don't let the two sons prove with their own eyes that this process is actually very simple, but it belongs to the category of 'discovery' in the "Invention Patent Law", and even the invention patent is not eligible to apply, Bai Dong is really worried that he will be regarded as a demon.

"The teacher said that all things in heaven and earth are mutually reinforcing, so the fire is extinguished by water, and the gold and iron are melted by fire, this kind of stone is called saltpeter, which is different from ordinary earth and stone, and can also be restrained by water, and when it is put into water, it will gradually melt and emit a cold atmosphere, so there is a vision of melting stone inside the ding and freezing outside the ding. Don't be surprised, it's not a miracle, as long as you have saltpeter, you can do the same."

Bai Dong smiled and said: "During the day, I boasted of having divine and ghost methods, that is for the soldiers, the secret of saltpeter ice making must be strictly guarded, not only the key to eliminating Mu Zhongtu, but also related to the precious saltpeter here." ”

This kind of stone can make ice in summer, that is a huge benefit, and naturally it cannot be leaked out.

The three of them tried it with their own hands, and found that as Bai Dong said, he could also conjure up ice, although the mystery disappeared, the interest was even higher, and even Yingquliang was childlike, and he refused to stop after conjuring up a few pots of ice.

Bai Dong smiled: "Okay, second brother, it's enough." I'll go and greet the kitchen army, bring the boiled black plum soup, and tonight we don't need to treat the army with wine and meat, just give the soldiers a piece of coolness. ”

(It's not about making gunpowder, it's too low-grade, hehe.) (To be continued......)
