ps: It’s a small matter. My father-in-law has a hernia and needs a minor surgery. I took him to have an examination today. I will be admitted to the hospital tomorrow. If I don’t have a son or son-in-law, I will have to go on a horse. So there are fewer updates. Don’t worry, this is not an excuse to make a dark note, nor will I stop updating. Even during my father-in-law’s hospitalization, I will try my best to keep up two updates every day, and never keep updating.

There is not only the grass sea, but also the Neihu River and hilly farmland. There is a three-meter-wide river outside the Yinma City. It is a tributary of the Hutu River. There is a pike with a pointed head and a pointed tail in the river. It is said that it loves to swallow the horse manure of Yiqu people, and it tastes very delicious. When the army was stationed in Yinma City, the young master Shaoguan and Nie Zhu caught them and ate them a lot, but Bai Dong refused to eat them. When he thought of this, he felt disgusting and couldn't even vomit.

Five hundred cavalrymen were selected from the old Yongdu army to guard hundreds of carriages and heading northwest. These old soldiers were like Yiqu people. They were all men who grew up on horseback. They were not able to borrow without stirrups, but they could clamp the horse's belly with their legs, shoot with bows and shoot in a variety of shots. Everyone had bronze war swords. They could use horse power to collide with horsepower, even without wrist power, and could kill people's heads. They were the first elites in Old Qin, only under the "light service camp" led by Ying Quliang.

Bai Dong had already issued an order, and the team was walking along the river, and warned all the way, and should not be careless. Ying Quliang had never seen him so nervous. Young Master and Young Official were even curious. Didn’t Jing Jian’s letters be displayed? There was no Yiqu garrison in this direction, and it was difficult for even the shepherds to meet. He didn’t know what his brother was nervous about... That day, he was also dizzy in the military tent and listened to everyone analyzing the military situation. Later, the Feiying sent a letter. A boy named Mo Shi, a Gongshu, actually touched the place where Mu Zhongtu, the new king of Yiqu, was located. At that time, Jing Jian read it loudly. Where Mu Zhongtu was, there were cattle and sheep like clouds, soldiers like rain, and there were as many as twenty flags tied with wild goose hair on the top!

Twenty wild goose flags mean that there are 20,000 elite soldiers; Bai Dong was right, Mu Zhongtu was too sinister, and the real elite soldiers were left by him on the Longdong Plateau, with the purpose of destroying the Qin army in one fell swoop.

After the letter was confirmed, Junji laughed loudly. He found Mu Zhongtu’s place, and it was indeed one of the several locations that Bai Dong had guessed before; the second was that he had gone all out of his chest. This time, Qin and Wei were all in a coalition, and they were also secretly competing. Pang Juan reported the battles one after another, which made him extremely depressed, and he almost had doubts about himself. Now it seems that it is not how powerful Pang Juan is, what a great victory is? It turns out that he met only some third-rate soldiers from Yiqu. The real battle to capture the king depends on your Grandpa!

Didn’t it be agreed that he would think of a plan to defeat the enemy after deciding Mu Zhongtu’s position? Young Master and Young Official were ready to fight every day. Waiting for the final decisive battle, even Ying Quliang was guessing how Bai Dong would come up with a clever plan to gather the elite troops of Yiqu. As a result, Bai Dong asked for an elite soldier and a hundred carriages, saying that he wanted to look west for the ‘Wujuwu Valley’ mentioned in Mo Line. Here is what Lao Qin needs most, which is related to the success or failure of the battle.

This time, the Yiqu ambush and the location of Mu Zhongtu is depended on an advanced "information system" than the opponent; so Bai Dong is even more careless. Although the army is full of Qin people, there should be no problems, but there is an exception in everything. It would be better if there is a "Qin traitor" or something. Moreover, Mo Shi has only walked through this place and heard some legends. The description is not very clear. It will be known whether there is the kind of thing he needs before he can find out. Therefore, he never explicitly said about the fungus, which made the old guy extremely itchy. It is probably not much better than the young wife who leaned against the door.

"I have traveled all over the world and visited Longdong. Although I have never been to Wujiwu Valley, I have also heard the legend about this valley. This is a devil's valley! People in Yiqu dare not approach, are you sure you want to go?"

Wu Juwu means "devil" in Yiqu's words. Although Nie Zhu is very brave, he has never been there back then.

"The devil? Perhaps there is the most magical thing there, which is more adorable than the messenger sent by God?"

Bai Dong just smiled. The stones in Wujuwu Valley would inexplicably emit fire. When they were shot down by lightning, they would make deafening sounds. Yiqu people would think that this is the power of the devil, but he hoped that this "devil" would really exist.

***

Wujuwu Valley does have the momentum of the Devil Valley. The wind at the entrance of the valley is howling, like a wolf howling. There is no grass in the valley, and snakes and insects are extinct. From a distance, the mountain walls and roots are grayish-white. Occasionally, cracked stones fall from the mountain walls, which will bring a thunderous flame. Humans always have awe of natural phenomena beyond their own knowledge and insights. Even ruthless people like Nie Zhu are no exception. The faces of the Yongdu old soldiers who entered the valley first turned pale. If it weren't for the ruthless military law, these men who killed people without blinking on the battlefield would turn around and run away!

"Outside the camping valley, load these stones onto the carriage, be quicker, the more you load, the better!"

Bai Dong first entered the valley and saw the gray-white crystal stones piled up like hills in the valley. He couldn't help but laugh, saltpeter! With this thing, the big plan was done!

Seeing the main general entering the valley first, the two young men followed in. The old soldiers had to get on with the bullet? Follow Bai Dong's instructions, they took these strange stones into the carriage, and soon filled more than a hundred large carts.

It was getting late, and I couldn't go back today. Bai Dong smiled and looked at Ying Quliang and the young master: "Second brother, brother Shaoguan, is it hot?"

"How can I not be hot, brother of the Bai family? My butt is wet."

Longdong was more than a month old. Now it is the hottest weather in the middle of the midnight summer. People will sweat even if they don’t move, let alone move stones. The young master Shaoguan complained: "Brother, these stones are not golden lumps, what are you going to move? You used 500 elite soldiers and hundreds of carriages just to get these stones back? There are many stones in the city of Yanma. Why do we need to run to Xu Yuan?"

Not to mention him, Ying Quliang couldn't figure it out. However, he would not complain like a young master and young official, but just looked at Bai Dong in confusion and waited for his explanation.

"Well, I like the appearance of this stone. It's not too much to get more back, right? By the way, thank you for your hard work, the soldiers, and I need to reward everyone tonight. The weather is so hot. I can't say that I will use my skills tonight. I will turn some swallow-land black ice into the flat ground. Do you still remember the iced sour plum soup?"

"Ice and sour plum soup, brother, aren't you joking?"

Not to mention foodie like Young Master Shaoguan, the sound of swallowing saliva was also heard in Ying Quliang's throat. In this hot weather, he had just sweated. If there was a bowl of iced sour plum soup... I couldn't think about it, it was too greedy. The sound of swallowing saliva was passed along the Qin army's ranks, and almost overwhelmed the howling mountain wind. Faced with the temptation of sour plum soup, who was still in the mood to ask Bai Dong what these stones were for?

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

A large wooden basin was placed in the center of the military tent. This was used to wash and wrap the wound cloth in the wound camp. This was made of new and unused. Bai Dong asked for it. The basin was 90% full of clear water. Three bronze tripods were placed in the water. It was about the size of a big old bowl, and the body of the tripod happened to be the same as the water level. The water could not flow in, and the tripod was not taller than the water surface.

Ying Quliang, Young Master Shaoguan and Nie Zhu looked at the wooden basin in amazement, unable to say a complete sentence for a long time. The weather is so hot that people want to be naked. No matter how much water they drink, they will not quench their thirst, but the water in the wooden basin is slowly freezing!

You read that right, it was just frozen, and a stream of air conditioning rose from the wooden basin and came to your face. It was so cool and comfortable!

The three of them looked at the three small bronze tripods, and there was water in the tripod. There was nothing else in the water. They just soaked the strange stones taken during the day. They reached out to try the bronze tripod. Sure enough, it was even colder here! The young master and young official was too curious. He circled around the wooden basin for a few times. While enjoying the rare coolness, he reached out to touch the bronze tripod, but was pushed away by Bai Dong: "Do you still want your hand? It will be frostbite!"

"Heianlang, are you...a human or an immortal? This...this..."

Nie Zhu looked at Bai Dong and his body trembled slightly. He had actually wanted to kill such a person?

The calm and calm as Ying Quliang, his face changed drastically at this moment. Summer turned into ice out of thin air, and it was not like the nobles of Yandi who took ice from the deep ice cellars hidden underground. This was beyond his understanding.

"I am a living person. If I don't have food to eat, I will be hungry. If I get sick, I have to take medicine. Don't treat me as an alien. Don't. Lao Qin treats me as an alien. He always likes to test medicine with me. It turns out that my mouth will also be swollen..."

He asked Ying Quliang and the young master to see the process of making ice on their own, but he didn't want to hide it from them. This is different from the invention of pen, ink, paper and inkstone. This is a miracle of luck that turns into ice on the ground in summer. If the two young masters don't let them prove it with their own eyes, this process is actually very simple. It just falls into the category of "discovery" in the "Invention Patent Law". Even the invention patent is not qualified to apply for invention patents. Bai Dong is really worried that he will be regarded as a monster.

"My teacher said that all things in the world are mutually generated and restrained, so the fire is extinguished by water, and metal and iron are melted by fire. This kind of stone is called saltpeter. Unlike ordinary earth and stone, it can also be restrained by water. Put it into the water and it will gradually melt and emit yin and cold air. Therefore, there is a strange phenomenon of melting stone inside the cauldron and freezing outside the cauldron. You don't have to be surprised. This is not a method of gods and ghosts. As long as there is saltpeter, you can..."

Bai Dong smiled and said, "I boast about having magical and ghost methods during the day. That's for the soldiers. The secret of making ice in saltpeter must be strictly protected. It is not only the key to the elimination of Mu Zhongtu, but also the precious saltpeter here."

This kind of stone can produce ice in summer, which is a huge benefit and naturally cannot be revealed.

The three of them tried it with their own hands and found that if Bai Dong said, they could turn into ice, but although the mystery disappeared, their interest became even higher. Even Ying Quliang was very childish and had to turn into several pots of ice before he could stop.

Bai Dong smiled and said, "Okay, second brother, it's enough. I'll go and greet the chef and take the cooked black plum soup. We don't need wine or meat to reward the soldiers tonight, so we will give the soldiers a coolness."

(It's not about making gunpowder, that's too low-level, haha.) (To be continued...)

ps:ps: Thank you for the reward of 10,000 coins from the brothers of "Swallow White":) Thank you for the reward of 10,000 yuan from the monkey, "Poison you ten thousand times", "Dark jockey, "What a cold ice":)
