Yao Changsheng suddenly opened his eyes wide and looked at Chu Jiu in surprise and said, "It won't be what I thought. I will use iron-sucking stone to pass the mountains and rivers."

"Yes, yes!" Chu Jiu couldn't stop smiling, obviously knowing how to joke!

"That's a mine, buried very deeply, and iron-sucking stones are useless at all." Yao Changsheng said with a serious look at him with a serious face.

"What if it looks like an open-pit coal mine!" Chu Jiu said with super optimistic.

"We won't be so lucky every time." Yao Changsheng looked at the naive and shook his head slightly.

"What if God opens his eyes!" Chu Jiu said with a smile, "Don't take it seriously, but I really want to!" He said with great enthusiasm, "To be honest, brother and sister are so powerful! You can also make muskets."

Yao Changsheng clenched his fists and coughed lightly, looking at him with deep and clear eyes.

"Ah! You are also amazing, and you are bound to be credited." Chu Jiu shook his mind and looked at him and praised him.

"Actually, the records in this musket book are very detailed." Yao Changsheng pointed at the musket channel placed on the round table. "The muskets fired stone bullets, arrows, and iron bullets with gunpowder. Now the Yanting army is also equipped. The muskets and cannons are made of metal. They were initially made of copper, called copper muskets, and later cast iron, called iron muskets. The metal tube-shaped firearms not only load gunpowder, but also contain spherical iron bullets or stone balls, thus setting a precedent for loading bullets in metal tube-shaped firearms. Yanting also has a special firearm battalion and a full-staff musket."

"Wait, why haven't we seen this firearm camp before?" Chu Jiu said immediately after hearing this.

"Guard the capital!" Yao Changsheng gently spit out four words.

"We are not qualified after a long time of trouble! Good things must be used by the emperor." Chu Jiu said with laughter and cry.

"Master, wait a moment." Yao Changsheng stood up and went to the study room, and brought the pen, ink, paper and ink.

"What are you doing?" Seeing this, Chu Jiu quickly emptied the place and asked him to put his pen, ink, paper and ink on the round table.

"Introduce the musket to the master in detail..." Yao Changsheng introduced the structure of the musket in the following time, all of which consisted of a front chamber, a medicine chamber and a tailgate, and spared no effort to tell the past and present of its musket.

This girl suddenly attacked again. Fortunately, she was very smart and had enough reserves, otherwise she wouldn't know how to endorse her.

"There are all in these books. "The General Yao of Wu Jing" reviewed more than 10 firearms at that time, such as rockets, artillery, gunpowder whip arrows, fireballs, trenchballs, iron-punched fire harriers, bamboo fire harriers, thunder fireballs, smoke balls, poisonous smoke shatters, etc., and detailed description of the components of gunpowder, and there are 14 kinds of gunpowder distribution systems..."

"So detailed?" Chu Jiu raised his eyes and looked at him in surprise.

"It's written in black and white!" Yao Changsheng pointed at the rice paper with his index finger, "The Song Dynasty was quite large and complete in terms of firearms. There were special departments in the manufacturing of firearms to study and manufacture various explosives and firearms. In order to encourage the development of weapons, the Song Dynasty stipulated that weapons inventors and creators should be given rewards and support, so at that time, people often presented their newly created weapons to the court."

"Why are you as weak as a little chick?" Chu Jiu sneered when he heard this.

"No matter how good the fire gun is, it must be used!" Yao Changsheng looked at him meaningfully and said, "This general is the general who suffers from suffering outside, but he can't resist the slander of the villain in the court. He is afraid that the gun gun is aimed at him! The emperor's ears are soft! No one is dragging his legs?" He looked at him with deep eyes and said meaningfully, "About it, I am still afraid that the generals will be very good at shocking the master. I must first calm the internal situation when fighting against foreign countries! I bow to the outside world, and I, the emperor, will do whatever I want."

"Bad! I can't stay in my house, so I'll dig my own grave, but I'll let my family take over all my nests, and I'll die even worse!" Chu Jiu snorted coldly, "I don't want to make progress and don't want to be united in the outside world. It's a good situation, which makes the country ruined and the mountains and rivers broken, the people's families destroyed and the people are displaced. Sinners!"

Yao Changsheng took a deep breath when he heard this and said, "In the battle against the Jin Dynasty, the army of the Song Dynasty had a considerable advantage, relying on the power of firearms, which could not only effectively resist the impact of the enemy cavalry team, but also often defeated the enemy soldiers. The Jin soldiers knew the power of firearms and tried every means to obtain the technology of making gunpowder and firearms. Later, after the Jin army captured Bianjing, someone dedicated this technology to the Jin people. The Jin soldiers were as if they had treasured, and immediately started to make a large number of gunpowder and firearms to counterattack the Song army. In the hands of the Jin people, they also introduced new firearms and developed a new firearm. Later, Yan Ting obtained it from the hands of the Jin people. Some of the technical craftsmen who made gunpowder and firearms were captured and some surrendered. Therefore, the gunpowder and firearm manufacturing technology mastered by the Jin people began to be used by Yan Ting."

"Grandma has traitors at all times." Chu Jiu said angrily.

"The Lord cannot say that. Those craftsmen are captured, and all the princes and ministers surrender. What can they do as little people?" Yao Changsheng raised his eyebrows and said to him.

"After all, it's the emperors and ministers who did not do anything." Chu Jiu controlled his temper.

"Dayan used a large number of firearms during the Western Expedition. When the Yan army attacked Nisha City, it built an anti-aircraft turret, and used 20 crossbows to bombard the city for 15 days, firing a large number of rockets, poisonous fire cups, and artillery shells. When besieging the capital of Dashi, it used iron cannons, which is the thunder we use now. The locals commonly call it the iron bottle." Yao Changsheng looked at him with bright eyes and said, "When the Yan army made artillery, it not only simply gunpowder, but also poisonous herbs."

"What is that?" Chu Jiu looked at him in surprise and asked.

"The poison ingredients include aconite, and crotons that are not laxatives. Wolf poison is actually wolf feces, arsenic, etc. Add gunpowder ingredients to make a pulp, strung with hemp rope, 1.2 zhang long and half a pound, which is a string. Then use old paper, asphalt, hemp skin, yellow wax and other substances to mix and apply it on the surface. Use a cannon to release it, and the poison gas can cause people to bleed and die from poisoning." Yao Changsheng said with a deep heart, "This has greater lethality."

Chu Jiu stared at Yao Changsheng and said in disbelief, "Oh... this huge big swallow has only been in a hundred years, why has it become like this?"

"I think the men of Yanting want to know too." Yao Changsheng sneered and said with a strong mockery, "Now I can only miss the glory of my ancestors!"

"They don't want to know, they just think about why their wealthy life is gone." Chu Jiu said seriously at him.

Yao Changsheng shook his head and laughed when he heard this, and it was full of mockery.

"Hey! Changsheng, you said, the court is not afraid of being learned by others when it is written in this book." Chu Jiu looked at him with dark eyes and said.

"The people must learn to recognize words first!" Yao Changsheng raised his eyebrows and said, "I understand this book, but it is very different from what I did when I did it." He laughed softly, "Besides, what are the servants in the yamen doing? They were surrounded before they could be done."

"Haha..." Chu Jiu smiled and said, "Family style is really important, it's more important than what we know!"

"I agree with the importance of family style, but I learned a lot because I spent three years in the Hanlin Academy and read all kinds of books." Yao Changsheng looked at him with a gentle and peaceful look and said, "I don't know everything. I am good at military affairs, but I am really not good at other aspects."

"Who said?" Chu Jiu immediately said when he heard this, "You are better than us in terms of economics!"

"What's more powerful? That's all learned now. It's not as good as my sister-in-law's wife!" Yao Changsheng looked at him with clear and upright eyes and said modestly.

"Hey! I'm so modest! You have better knowledge than us and have stronger learning ability." Chu Jiuqing looked at him with his eyes as bright as the moon.

"I am going to the next level based on the existence, and the master has gone from nothing to something. In this way, who is better?" Yao Changsheng looked at him with deep and clear eyes and said seriously.

"Changsheng quickly clean up the table, the dumplings are cooked." Tao Shiwu walked in with the dumplings.

"I'll do it." Chu Jiu took away the musket and sword.

Yao Changsheng quickly put away all the pens, ink, paper and inkstone and the writing.

Chu Jiu watched Changsheng fold up what he had just written and walked out, "Changsheng, what are you doing?"

"Burn it." Yao Changsheng raised his painting and said.

Chu Jiu nodded in a clear way. It is true that these things cannot be handled casually, and it is more appropriate to burn them.

In this regard, Changsheng is very cautious.

After eating the dumplings, Chu Jiu left with his sword. Before leaving, he repeatedly reminded Changsheng, "I'll wait no matter how late my brother and sister are awake!"

"Yes!" Yao Changsheng responded quickly, sent him away, and went back to the wing room. He looked at Ni'er who was sleeping soundly on the bed. He sat on the edge of the bed and held her hand on his lips, "I should be punished if I am so tired!" After letting go of her, he simply went to the kang, sat by the window, took a book from the kang, and started to read casually.

Chu Jiu took the sword in his hand and went home, "Son, the sword made for you by your master." He handed the sword in his hand directly to Chu Zeyuan.

Chu Zeyuan took the sword with both hands, and looked at him with his eyes as bright as black grapes and said, "Master is back."

"Yes!" Chu Jiu nodded with a smile, "I just came back from your master's house."

"Did Daddy eat it?" Chu Zeyuan asked with concern with big watery eyes looking at him.

"I've eaten." Chu Jiu looked at him and smiled slightly, "Where is your mother!"

"Mom is feeding my younger brother." Chu Zeyuan pointed to the bedroom and said, "I'm writing big words."

"Don't you look at the sword your master gave you?" Chu Jiu tapped the sword in his hand with his chin.

"Oh!" Chu Zeyuan looked at the sword body wrapped in animal skin, "I have to make another scabbard."

"Leave this to me." Chu Jiu looked at his son with a smile and said, "I promise to get you a powerful sword sheath."

"Thank you, Dad." Chu Zeyuan happily drew out the sword, his whole body was pitch black, simple and unpretentious, but he was so cold.

"Dad, let's try going to the martial arts gym." Chu Zeyuan ran out with an arrow.

"Boy, hurry up." Chu Jiu chased after him worriedly.

The father and son came to the weapon stand in the martial arts training ground, with swords, guns, swords, and halberds on it, with all kinds of weapons.

"Dad, hold the black iron stick." Chu Zeyuan said to him with his little face raised.

"Let me try it! Don't hurt yourself." Chu Jiu looked at him worriedly and said.

"Dad!" Chu Zeyuan Shuiying looked at him with big eyes and said coquettishly.

"Okay! OK! Just a moment." Chu Jiuzhen couldn't stand his son's big wet eyes looking at him, "I'll say it first, my arms are numb and you don't cry." As he said that, he pulled out an iron stick as thick as a baby's fist from the rack, and tilted it to the ground and held it in his hand.

"Yeah!" Chu Zeyuan took a step back, grabbed the hilt of the sword, raised it high, his chubby little face was now stern, his eyes fixed on the iron stick.

"Huh..." Chu Zeyuan shouted loudly and chopped the sword in his hand towards the iron stick. With a sound of beard, the iron stick was cut into two pieces like cutting tofu.

Chu Jiu was a little unexpected that this sword was really as sharp as mud. After all, he had never heard of his younger brothers and sisters who could forge a sword.

The sword in the hands of my brother and sister was picked up by accident. It was good to have a medium-to-high level forging, and now it is a bit unexpected.

Chu Jiu looked at him with eager eyes and said, "Come on, let Dad try it." He took the sword from his son, took the broken iron rod, took a few steps back, and cut the iron rod as if he was cutting a radish.

Chu Jiu was so excited that he was a little worried about this weapon in his son's hands. He bent down slightly and looked at Chu Zeyuan, and said in a gentle tone, "Son, you can put this sword first, and use it when you grow up. It's too sharp. I'm afraid I will hurt you."

"Dad! Look at how tall I am now. This sword is obviously only available when I grow up." Chu Zeyuan looked at him with a crystal pure eyes and said with a smile, "This one should be hung in my room." He asked, "I also have to make me a beautiful tassel."

Since his younger brother was born, Chu Zeyuan has moved to the front yard and has been with his father for a long time.

And sometimes my father talks with others about political affairs in the study, no matter whether he can understand it or not, he will let him sit honestly and listen carefully.

"You boy." Chu Jiu stretched out his hand and pinched his perky nose and said, "Do you want the sword sheath to inlaid with jewelry!"

"No, no. It doesn't need to be so gorgeous." Chu Zeyuan looked at him with innocent eyes and shook his head slightly, "Practical! It can protect my sword."

"Let's go back to the room to talk." Chu Jiu said, holding his hand.

"Dad, are you going to find the master just to get the sword?" Chu Zeyuan raised his eyes and asked at him.

"No, your master has made good things again." Chu Jiu said to him with a spring breeze-like smile on his face.

"What good thing? Where is it? Let's take a look." Chu Zeyuan's little face was lit up instantly, and he said excitedly when he looked at him.

"I didn't bring it to Mr. Yao's hands. Your master is too tired and sleepless. When I went there, people were sleeping, so there was no disturbance." Chu Jiu pulled him and said as he walked.

"Then when will I see it?" Chu Zeyuan looked at him with anticipation and asked.

"I can't explain this clearly. Anyway, I will definitely see it before I leave." Chu Jiu looked at him and thought about it.
