Meng Tian thought of this. Immediately gave a copy of the book to King Qin and Wang Jian to inform King Qin and Wang Jian of his guesses and plans. But this letter did not reach the hands of King Qin and Wang Jian quickly, because. This letter was staggered by mistake with King Qin's team. Then it was time to catch up with King Qin's team. Meng Tian's army had already driven for a day. In this way, the Qin army wasted a day's journey in vain.

When Wang Jian saw the letter, he did not pay attention to it. This error was ignored.

One more thing Wang Jian guessed in his heart was where the Hu people had gone. At this time, the army was already stationed in place. It was already dark, and it was impossible to find any trace of the Hu people.

Li Mu was also pondering Hu Ren's intentions at this time. Li Mu looked carefully at the signs on the map. Routes capable of marching. Li Mu has sent more people to search, but there is no news he has received. Li Mu felt that something was wrong. An army of Hu people who still had combat strength disappeared. This is definitely not a good thing. But where the hell is that. Li Mu was puzzled.

The night was already deep. After the king of Qin finished dealing with some political affairs, he stood up and walked around. Stretch your muscles. Zhao Gao obediently served some tea. After the king of Qin finished drinking, he was about to go outside the tent. Zhao Gao picked up a cloak and walked out of the tent with him.

King Qin unknowingly came to Shang Wen's tent. I saw that Shang Wen's tent was still lit.

"It's so late, Mr. Qin hasn't slept yet." King Qin muttered to himself. Remembering the events of the day. In fact, the main responsibility is to blame. If he could handle it at that time, there would be no matter for Mr. Qin. Mr. Qin is good at weapon manufacturing, and it is really difficult for some strong people to ask him to do things that he is not good at. Come to think of it. King Qin was about to take this opportunity to apologize to Shang Wen.

Zhao Gao saw that the King of Qin was about to enter Shang Wen's tent. I opened my mouth to make a report. Seeing this, King Qin immediately stretched out his hand to stop him. Before Zhao Gao could shout, he swallowed it stiffly.

King Qin lightly entered Shang Wen's tent, and when he saw Shang Wen constantly talking something, there were a lot of drawings thrown on the ground. King Qin bent down and picked up one and looked at it. I saw that the symbols marked on it were all symbols that I couldn't understand. And the style of the weapon is also very strange. King Qin then picked up another one and looked at it. The same goes for it. King Qin wanted to ask. Seeing Shang Wen thinking about something. Constantly adjust the ruler.

Shang Wen's drawings are all about muskets and artillery structures. For some necessary parts, Shangwen has made a detailed plan. Especially some special parts. Hydraulics. Shang Wen broke down about twenty or so diagrams. The unit of distance used is the centimeter that is now. The annotated symbols are all commonly used symbols today. Of course, these Qin kings can't understand it.

The history of muskets goes back hundreds of years. Muskets of various periods were constantly evolving, solving some of the difficult problems in firearms. And what Shang Wen has to do is to jump directly to the situation that the current materials can solve.

There are two types of muskets that Shanvin planned to make. Smoothbore guns and rifled guns. As long as the development of smoothbore guns is aimed at the six countries of the East. At a distance of 50 yards, this gun is extremely powerful. However, when the distance is widened, the accuracy of the target shot is greatly reduced. And rifled guns, mainly equipped with the Qin army. This musket is to be equipped with Megnier bullets. Loaded in this way, shooting accuracy, power. are higher than the smoothbore guns of the six eastern countries. Prepare for the war of unification in the future. And the export of smoothbore guns will bring a lot of money. Just by exporting gunpowder, you can earn a lot of gold. Because the six countries of the East do not make gunpowder.

In addition, Shangwen had to develop artillery. For artillery. will greatly accelerate the brutality of the war. In this way, the last bit of strength of the six eastern countries will be quickly disintegrated. What Shang Wen has to do is to export iron artillery. Because Shang Wen knows it clearly. After some time in the event of these guns, they explode. In this way, the artillery can no longer be used, and in the end, it will have to be bought here. The Qin army was mainly equipped with copper artillery. These guns are to be equipped with an accurate gun sighting system. These can be carried directly from the rocket launcher. Then there is the processing of gunpowder. This is followed by rifling. For recoil. Shang Wen can only look at the precision of the processing of iron products to be absolutely equipped with a hydraulic system. These need to be manufactured before they can be continuously improved. And it's all based on iron-smelting production. Come to think of it. Shang Wen felt worried, with the current level, the changes were very limited. Because the chemical process is basically just getting started. As a result, there is a huge threshold for the further improvement of gunpowder. You have to do it all yourself. Shang Wen's biggest concern is the development of explosives. Thinking about the explosive nitroglycerin, Shang Wen's scalp was numb, why did he have to be a Nobel Prize for a while. If this thing doesn't work well, it will go to the west. But who would. Do you want to find a substitute for the dead?

King Qin saw Shang Wen stop his pen and hold his chin, as if he was thinking about something again. Without turning his eyes, he looked at the drawings on the desk. It's as if there's something wrong with it.

King Qin cautiously sat aside and watched Shang Wen ponder the problem. There was no movement at all. Fear disturbed Mr. Qin's thoughts. The king of Qin understood that the Qin army had new weapons again. With new weapons, the Qin state will move faster towards unification.

The night was quiet, in a small village built by a river, but it was unusually quiet. "Poof." The sound of metal stabbing into **. A man who got up late to go to the toilet was killed.

"Ahh A shrill woman's cry woke up the people in the village.

"Bastard. Quick, get in and kill everyone. A Hu man commander ordered.

"Bang." A door was slammed open. The man who was about to take a look was knocked to the ground. Before he could see what was going on, he was slashed and killed by the Hu people with a knife. A few Hu people who rushed in quickly turned to the back room and saw half-naked women, all of whom were ready to move. Soon a nest was on the line. Then the woman began to scream.

"Bastard." The bearded man rushed in with a knife in a rage. A group of Hu people were seen surrounding a woman, who had been pressed to the ground. The commander of the Hu people lifted his scimitar and slashed those people to death. Those Hu people didn't understand what was going on, so they whined in confusion. The woman panicked and tried to dodge, and the commander of the Hu people was also killed.

Carrying a few heads. The commander gathered his subordinates. Throwing down the head, he said loudly: "Wang Khan has repeatedly instructed us to kill quietly and go in. Now, it's because you didn't control your own **. The matter was revealed. As he spoke, he stared at Hu Ren fiercely.

"You, you." Hu Ren pointed to a few people and said.

"Stand up for me." Commander Hu said coldly.

Those few people stood up weakly.
