"Mowgli's idea, you can talk to Yun Hao!" Li Er's tone was very lonely. Yun Hao was surprised, except for the night before the Xuanwumen Incident, he had never seen this kind of expression on Li Er's face again.

"What Zhao Gong means is that our army is weak and it is impossible to fight the enemy in the field. And if it is guarded in Chang'an City, it will undoubtedly give up the entire Guanzhong to the Turks. After the Turks poisoned Guanzhong, the army on the Hebei front would also have no food to use. At that time, Datang will fall apart. Even, it is not even said whether the relationship can be preserved. ”

"Don't spit out, I'm coming!" Li Er took a deep breath and said, "I plan to empty the treasury of Chang'an, and I want to persuade Jieli to withdraw from the army. However, before Jieli retreated, he needed to hurt the Turks once. Only those with strength can be qualified to negotiate. What I mean is that you go and take Zuo Wuwei to hurt Jieli once. How is it? ”

Yun Hao closed his eyes and was silent, humiliated! is really humiliated, the dignified Tang Empire actually wants to empty its treasury to make the alien iron hoof retreat. This is not the cowardly Great Song Dynasty, this is the powerful Tang Dynasty.

A historian once said that only when we understand helplessness from history can we truly understand history.

Li Er was helpless and had just taken the throne of his father. The domestic rebel forces have not been completely pacified, and the armies that Datang can fight are all confronting Luo Yi in Hebei. More than 100,000 Turkic troops have already reached the gate of the capital, and the edifice will fall soon. Li Er had to do this! Yun Hao could be sure that Li Er's heart was dripping blood.

"Say it! Let me fight the Turks all the way. Yun Hao took a deep breath, if he couldn't teach the Turks a lesson. Li Er was not even qualified to negotiate, and the Turks had always been desperate for the weak.

"According to the speed at which the Turks are advancing, the advance led by Ashina will reach the Weishui River in four or five days." Li Er looked at the sand table and said lightly.

"Is it Ashina Tu who slashed Dugu Yanyun?" Yun Hao felt his eyelids jump.

"Yes!" Li Er took a deep breath, his eyes full of hatred.

"I'll come back with his head, if I can find it." After Yun Hao finished speaking, he walked out of the Martial Arts Hall without looking back.

Damn it, it's a thief, and you have to earn your life to live in this world. Turks, if you don't kill your green, even if you haven't eaten leeks. As for whether the Turks eat leeks or not, it is not in Yun Hao's consideration.

Zhang Miaoke silently applied wax to the armor, and Dugu Wanwan tied a bundle of armor silk on the dark armor. Xin'er and Yuan'er silently helped Yun Hao prepare clothes, but they didn't need to prepare many clothes. This time, at most, he went to the edge of the Wei River and fought with the Turkic forwards. The most important thing is how to bring Ashina's head back. Dugu Wanwan needs this thing to comfort his father's spirit in the sky.

Yun Baobao dragged the panda Xiaohua and walked aimlessly at home. He realized that nothing was right with the people in the family today, and everyone walked as if they had been chased by wolves. The generals all wore helmets and armor, and they usually did not wear armor. The puzzled Yun Baobao raised his head and asked, "Brother Dog, what's wrong with them?" ”

"It's going to be a war, fight the bad guys!" The scar on the dog's face glowed with a dark red light, and he had to go to the battlefield with Uncle Yun no matter what. Bullied by aliens since childhood, the dog craves war and longs for the battlefield. He loved the sight of the blood of aliens, such as the Koreans lying in the snow covered in blood.

"The baby is also going to beat the bad guys, Brother Dog, can you take me there? Xiaohua is very powerful, and the dogs on Zhuangzi are afraid of it. Yun Baobao hugged the panda Xiaohua and tried to keep its head high. He also opened his lips with his hand, revealing Xiaohua's fangs, trying to create a vicious expression.

"No! The bad guys are powerful, more ferocious than wolves. Little Flower can't beat them! The dog shook his head, and he heard that the Turks, who were fiercer than the jackals, could not be dealt with by a bear.

Yun Hao is also thinking of a way, this time he has no geographical advantage to rely on. It was completely necessary to fight the Turkic cavalry on the plains, and the powerful eight-bull crossbow could not be counted on. Despite several improvements, this thing is still too slow to reload. When the cavalry rushes over, it can generally only fire two rounds.

Fighting on the plains, the distribution of cavalry was relatively scattered. The powerful penetrating power of the Eight Bull Crossbow cannot be converted into sufficient lethality.

Trebuchets are obviously not good either, the same is a matter of rate of fire. In the face of very scattered cavalry, the bombs dropped by trebuchets usually do not kill many people. Now, Yun Hao needed a powerful covering weapon, such as the Stalin Pipe Organ.

Yun Hao got a lot of saltpeter, and after adding water to the large vat, he kept stirring it with a wooden stick. There was a crackling sound inside the vat, and the saltpeter was rapidly merging with the water.

"Boy, what are you doing again?" The old fisherman who heard the news immediately put down what he was doing. Generally speaking, Yun Hao just needs to settle down and do something. A lot of people will die, because this kid seems to be very knowledgeable about killing weapons.

"Something that makes explosives fly out on their own!" Yun Hao was so busy that he couldn't even raise his head, and the old man saw Yun Hao's focused. also found a big wooden stick to help Yun Hao stir vigorously.

After vigorous stirring, the saltpeter and water are soon fully fused. Yun Hao covered a large vat next to him with a thin linen cloth. Saltpeter water is poured onto the fine linen cloth, and in a short time a thick layer of impurities is left on the washing cloth. The saltpeter water in the tank is no longer so turbid. It has a milky white color.

Yun Hao scooped out the saltpeter water again, this time the vacant vat next to it was covered with three layers of linen. After this filtration, the water in the tank is much clearer. After filtering it three times, the vats were covered with as many as seven layers of linen.

After getting relatively pure saltpeter water, Yun Hao put them into a distillation pot and boiled them. The shoin used to make sulfur, and there were many such pots. At present, the academy produces more nitrocellulose, and gunpowder, which is time-consuming and labor-intensive, and the power is not enough, has been in a semi-suspended state. This is also something that cannot be helped, the cost of gunpowder is indeed higher than that of nitrocellulose.

Waiting for saltpeter water distillation over there, Yun Hao found a cauldron here. I got a whole pot of sugar and started stir-frying!

The old fisherman didn't know why, so he could only follow suit. The taste of the sugar fried was very sweet, and the apprentices next to him had the urge to grab a handful and taste it. White sugar is not easy to do in Chang'an.

Yun Hao turned a blind eye to these gluttonous guys, and under the constant stir-frying, he actually fried the sugar. White sugar, which has a burnt taste, is no longer favored. The apprentices stood aside in great disappointment, not knowing what this Duke of Chu was going to do.

"Go! Go! Go! Go! Go! Let's all play at the same time! Seeing Yun Hao's unprecedented seriousness, the old man drove out all these young guys, leaving only two Mo family disciples.

After the sugar is fried, the saltpeter water over there is almost distilled. A spicy taste came over the still, leaving countless colorless transparent prismatic crystals inside the still. This is the legendary potassium nitrate, and this thing is a very good fertilizer. But now, Yun Hao prefers to make this thing into a killing weapon.

Yun Hao began to experiment with the ratio of white sugar and potassium nitrate, from one to one to one to nine, and put them into several bamboo tubes. One end of the bamboo tube is sealed with mud and dried, and the other side is sealed with fire paint.

After the fuse is lit, bamboo tubes rise from the ground. It's like a drill monkey, but the height is far more than that of a drill monkey. The things used to make rocket boosters in later generations can't compare to the drill monkey.

"Boy, I heard you're going to face a Turkic army. What do you do with these things? The old fisherman was a little puzzled, could it be that Yun Hao was tinkering for a long time, just to get a firecracker to play?

"It's a good thing, just put it in rows on a wooden shelf. If you make two more iron bars to make rails, and put explosives in front of you. A large number of bombs can be released in a short period of time, which is a devastating blow to the enemy's cavalry group. When Yun Hao said this, all he thought about was the scene of Katyusha's cannon fire. Dense explosions can kill all creatures on the surface within the area.

Although the fisherman had never seen Katyusha, he was not lacking in imagination. Just think about it, how terrible this thing is. Countless shells fell from the sky at the same time, followed by scattered steel balls and lead. What the hell, can there be a living person?

Through the experiment just now, Yun Hao found that four to six, such a ratio shoots the farthest. Loaded with five pounds of such a thing, it can be shot on the other side of the mountain. Now the people who went to look for the bamboo tube have not been able to come back.

Now Yun Hao uses two bamboo tubes, and the front one is filled with nitric acid explosives. The latter part is a booster, of course, to increase the lethality. Anything like lead and steel balls was added, and pointed cones made of wood were screwed on bamboo. A standard rocket artillery shell was born, and with a terrifying range of 5,000 paces, it can be proud of any weapon of this era.

When the loud explosion came, the smoke in the distance was already steaming in the air. The old fisher was so shocked that he couldn't close his mouth, and muttered: "If this continues, the war will develop into a contest of who can fight farther." Your weapons are out of my reach, but my weapons can't reach you. The bravery of the individual will launch the stage of war. ”

"No, it won't! A great man once said that the decisive factor in war is still people. The bravery of the soldiers, who have sacrificed their spirit, will always be the most valuable thing in this world. These things are just an extension of the bravery of soldiers. Yun Hao knew that even in the future generations where guns were rampant. The sacrificial spirit of a soldier is as important as the courage of iron and blood.

"Hopefully! I really don't know what the war will be like if it continues like this. The old man will prepare what you need in the shortest possible time. When you go on the expedition, the old man will go with you. I want to see what it will be like if thousands of bombs explode at the same time. ”
