Aunt Osmanthus is also a clever person, and when she saw that Li Ziyu was looking for a housekeeper, she immediately took her two sons out and thoughtfully closed the door.

Bu Jiu waited for them to enter the West House, and also opened the door and walked into the courtyard, listening vigilantly to the movements around them.

Li Ziyu saw that only himself and Wang Tiehammer were left in the room, so he took out a piece of paper from his arms and handed it to Wang Tiehammer.

"Uncle Wang, take a look, can you make this thing?"

Wang Tiehammer took the paper in his hand and looked at it carefully for a long time. I saw a round pear-like thing drawn on it, with a handle on it, and a thread on it.

What is this? Wang Tiezhu looked at Li Ziyu suspiciously.

"This is called a grenade, and it is a very lethal weapon." Li Ziyu pointed to the drawings and explained, "Look, it's filled with explosives that can be detonated, and this is a fuse. As soon as you pull this fuse, it will explode. Uncle Wang, can you make this thing? ”

"How lethal is it? Explode? What's the explosion method? Wang Tiezhu's eyes lit up.

Before settling in Shiyan Town, he had been on the battlefield and fought the enemy face to face. He knew how much the quality of weapons played a role on the battlefield, and he knew that good weapons would enable more soldiers to save their lives.

If the grenade Li Ziyu said can really achieve the effect she said, how many fewer soldiers will die in the Xinjiang over there? The relative enemy will die a lot, doesn't that mean?

"Let's put it this way, if a grenade explodes, three of your houses will be razed to the ground."

"What? Are you telling the truth? ”

"Of course it's true!" Li Ziyu replied extremely seriously.

"Okay, I'll try. Fight to get it out! Wang Tiehammer's hand holding the drawings trembled slightly, he was excited.

He couldn't wait to start the furnace immediately. Hit it out early and see how powerful it really is.

"Uncle Wang. You have to keep this thing a secret! No one can tell! If it leaks out, what awaits us, I don't say, you can imagine it! Li Ziyu said solemnly.

Now the weapons of the ordinary soldiers of the Daye Dynasty army are basically broadswords, and the generals have swords, but most of them still use broadswords. Because on the battlefield, the final decision is often hand-to-hand combat, which makes the sword too inconvenient.

In ancient times, military exploits were judged by human heads. The number of heads determines the promotion of a soldier or general. Therefore, if it is easy to cut off the head, the big knife is the first choice.

But if a weapon that is more convenient than a broadsword appears. You don't even have to fight enemies in close combat. Once this news is leaked, it will trigger unimaginable consequences. As a developer, Li Ziyu and his younger siblings are very likely to be killed. You can imagine what kind of disaster will happen!

As soon as Wang Tiezhu heard what Li Ziyu said, he immediately realized the seriousness of the matter. The initial excitement on his face was also wiped out by the fear of the moment. His face was as pale as paper. I thought about it more than ten years ago. I was ashamed and panicked in my heart, and I felt that I had no shame to face Li Ziyu.

He only thought of the soldiers on the battlefield, but he didn't think of the sinister way of the world and the greed of human nature. After so many years of understanding and honing the world, he is still so naïve, and he is not as knowledgeable as a child. Alas, I am really a fool of my age, and my past experience is not enough to teach me a lesson?

Li Ziyu saw Wang Tiezhu's face change color, and knew that he was going to his heart. That's enough.

She was just afraid that he would be excited and shouted all over the world, but he thought it was a good thing in his heart. There is no awareness of the unguarded mind and the consequent awareness of the consequences of shaking the earth and shaking the mountains and tsunami that will ensue.

She now regretted it slightly, she shouldn't have told Wang Tiehammer about it before she had already pounded out the potassium nitrate.

However, she was also afraid that it would be too late. Who knows when the two countries will fight? She just wanted to develop gunpowder and grenade shells at the same time, which would save a lot of time.

She knew that once she used the grenade, she would not be able to hide it, and sooner or later the gunpowder formula would be handed over to the imperial court. She just wanted to make a protective thing for her younger siblings at the first time, and catch the enemy off guard at the critical moment.

"By the way, Uncle Wang, after this grenade is developed, it will be mass-produced. But what if there are no raw materials? Where can you buy so much iron? ”

Li Ziyu saw that Wang Tiehammer was a little embarrassed, so she naturally changed the topic. She knew that Wang Tie's hammering was a complete set of things, and his iron-striking skills were also very exquisite, otherwise she would not have found him.

"You don't have to worry about this, I have channels. Otherwise, what will I do if I have been striking iron for so many years? Wang Tiezhu saw that Li Ziyu no longer talked about the previous topic, and at the same time, he breathed a sigh of relief in his heart, and regained his former self-confidence.

"Oh? Isn't copper and iron controlled by the imperial court? Can you get it all? Li Ziyu became interested.

"Actually, I learned this skill from my master. The master had no choice but to stop striking iron, so I had to set up my own door. It's a pity that I only learned the master's skin, and I was embarrassed by the master. Wang Tiezhu's face was annoyed and ashamed, and his heartbroken look made Li Ziyu secretly wonder.

Who is his master? As far as Li Ziyu knows, Wang Tiehammer is quite famous in Shiyan Town. The ironware is meticulously carved, and the details are used to see the effort. The quality is also first-class and good, and it is deeply loved by the people in the vicinity.

Of course, the imperial court only allowed folk blacksmiths to make ordinary everyday items of the people. For example, shovels, pickaxes, sickles, iron pots, etc. Swords, guns, swords, halberds, and the like are strictly forbidden to fight, otherwise they will be punished as treason.

Therefore, Li Ziyu became interested in the reason why Wang Tiehammer's master no longer struck iron. So he asked, "Who is your master?" Why didn't he strike iron anymore? Is there any reason? ”

"My master's name is Lei Shi, and he currently lives in Shiyan Town. The Lei family started with military merits, and the ancestors once followed the emperor and is now the grandfather of Emperor Jingtai, and he has fought the world. He was also named the King of Chu, but was rejected by the ancestors of the Lei family. Then Rapids resigned from his official position and settled in the southern Autumn City. ”

"Then why is Thunderstone here? Did the ancestors of the Lei family strike iron? And why don't you strike iron anymore? ”

Wang Tiehammer hesitated for a moment, shook his head and said: "I don't know the specific details, I only know that the master no longer strikes iron because several mountains in the south of his house are iron mines." Perhaps in order to dispel the suspicions of the imperial court, the Lei family announced that they would no longer make ironware. I heard that 80% of the iron ore produced by the iron ore was returned to the imperial court, and of course the imperial court would also give a few dollars. The iron ore I can get is actually scraps, that is, iron filings. The serious iron ore was given to the imperial court, and since the master didn't strike iron, the iron filings were useless, so he had to cheap me. ”
