It's peaceful here in Chang'an! Cheng Hong was having breakfast this morning! Li Tai took a sip of soy milk and said, "Cheng Hong! That steam engine has come out! When are you going to tell me about that white tech of yours? ”

Cheng Hong was stunned: "What white technology?" And the steam engine, okay? Experimented? Don't pull and pull and turn into a cannon battle when the time comes! ”

Li Tai rolled his eyes at Cheng Hong: "What kind of artillery battle?" I set up a small loop rail there and ran for a day and a night with twenty carriages! Except for the occasional stop, the water and coal are almost not stopped!

Do you take the train seriously? Over there, I started working on the steam engine, and then assembled the car, and then pulled the car and ran away, and you didn't even look at it! ”

Cheng Hong scratched his head, and said embarrassedly: "I'm sorry!" Recently, I've been busy giving lessons to Li Yu and Li Su! I'm too busy! Didn't you see that Li Su can now go to the steel mill account room to work and study? ”

Li Tai nodded: "Yes!" But that's the end of the train over there! You're ready for mass production! Now the passenger cars are hung in the cargo compartment to transport copper coins!

These grandsons in the south are really rich! Look at what's shipped back! Forget about the rust on the copper coin! These grandsons even have black rust on gold! The silver has green hairs! I said, why don't people have money! It's all in their hands! ”

Cheng Hong nodded: "Isn't it!" There is no meaning for coins not to circulate, and it will do all kinds of harm to the people and the country, and there is no benefit! ”

Li Tai said here again: "Don't say anything else, when will you let me see your white technology!"

Cheng Hong was inexplicable: "What kind of white technology?"

Li Tai said: "Didn't you say that my steam cannon is black technology? What skills are wrong! It's a mess, you take out a non-black white technology and show me! ”

Cheng Hong suddenly realized! That's what happened! What did I think about white technology!

Cheng Hong nodded: "Okay!" You wait! I'll go to my study and get the drawings in a moment! But keep this thing away from fire and iron! If you want to mass-produce, it's best to build another workshop! ”

Cheng Hong had long planned to take out the gunpowder, and the people who mastered the gunpowder were none other than Li Chengqian or Li Tai brothers, and in the end, Li Er mastered the production! It just so happens that Li Tai is interested, loves research, and is the best object to shake the pot! Where to find such a good backstabber!

And after the gunpowder is produced, if you don't talk about the war, you can say how much trouble will be saved by opening mountains and bombing roads on Baoqi's side! Plenty has complained more than once about the lack of manpower! As soon as this gunpowder comes out, who will compete with the cracked stones!

As soon as Li Tai heard this, he finished eating a few bites and pulled Cheng Hong to see his artillery! Cheng Hong was so helpless that he had to go to the study with him to get the drawings!

"It's as simple as that?" Li Tai looked at the gunpowder ratio with a questioning face!

Cheng Hong nodded: "Then how difficult do you think it is!" A true word is transmitted, and a false word is passed on to thousands of books! This thing can't be ground with iron, it must be made of hardwood!

If there is a spark, the whole roof can be blown off! Also, you'd better make a few samples! It's better to leave it to my father to find someone to get it! Remember not to operate in an open flame! Neither does the Dark Fire! ”

Li Tai nodded, took the gunpowder formula and grenade and hurried away! I don't know how much he listened to what Cheng Hong said!

Cheng Hong shook his head and went to the steelmaking workshop to see the train! It's a generational thing! A steam locomotive represents the rise of the industrial age!

Walking to the steel mill, a locomotive on the circular track pulled twenty wagons "Kuku" panting and galloping! Maybe it's not much! It's really not slow!

Cheng Hong nodded and called Sun Ran, the person in charge of the steel mill: "Give me thirty of this model!" Rest assured, I'll talk to your son-in-law about money! If you can't produce it in a month, I will change to a housekeeper who can produce in Wei Wangfu! ”

The eldest grandson here heard it: Yes! This is another ancestor! I thought that King Wei would be able to stop for a while without tossing! I didn't expect to leave, King Wei came, Cheng Hong! This steel mill can't stop!

After Cheng Hong finished speaking, he left leisurely! I'm going to see what's going on with Lee Tae! After all, it is flammable and explosive, and he is not the only one who is unlucky in case of "boom"!

Enter the experimental hut of the King of Wei, where Li Tai is directing people to move things inside! Wearing a full set of armor, Cheng Hong looked at it: "What are you doing?" Want to wear this for gunpowder? What will you do if there is a Mars? Hurry back and change your clothes! ”

Li Tai looked at the armor! looked at Cheng Hong again, and felt that this thing was a bit too much! Hurry back and change clothes!

Cheng Hong saw that all kinds of charcoal were brought in here! Without saying a word, reach out and start grinding! Wait for Li Tai to come back and be in charge of grinding saltpeter and sulfur......

Li You, Li Yu, and Li Su brothers are on holiday today! Still running around with a bunch of kids! Since the last time Li You was stung by a bee, he has become the child king of this group of children!

As for Li Su, this product has made greater progress! Now Li Su can make up lessons for ordinary children! And it's okay to help Xiaodouzi's family settle accounts or something, and it's fun!

On this day, a group of people met at the school gate! Li You and Li Yu took a big gourd, which was filled with red dates and honey water, which was not an expensive thing, the dates were asked for in the kitchen, and the honey was poked by Li You and the three sons of the Orion family!

It can be said that they are all the fruits of their own labor, and they are beautiful to drink!

A group of people are discussing where to go! At this time, Xiaodouzi said: "Let's take a look at the train made by Mr. Li Tai!" I heard that you can run without livestock! And it's running fast! ”

A group of children are chattering, you and I are starting to say their own hearsay!

"I said it! That thing eats coal! ”

"Listen to me, Aya, that thing not only eats coal, but also spews black and white smoke! And it's going to be called! It's louder than a cow! ”

"Wow! It's true? ”

"But how do we get in!"

"Let's just say we're looking for a teacher!"

"No, no! ……”

Finally, a group of people are tiptoeing in to see the train! When I walked to the door, I was just in time for Li Tai to change clothes and come back!

Li Tai saw them tiptoeing and asked, "What are you doing?" Here Li You said: "Fourth brother, we want to see the train!"

Li Tai nodded: "Oh! I thought what was the matter! Let's go! Come in with me! Come out when you've seen enough! Don't run around! There are too many carriages and horses in it, and they are all ironware, don't bump into it! ”

A group of people happily agreed! I was finally able to go in and have a look! It can be said that except for Li Su, who came in when he came in as a work-study in the bookkeeper, no student has ever come in!

After all, this is not the place to play! Although this steel mill has brought them many benefits, it is a secret for children! I'm finally happy to be able to go in and have a look today!

After Li Tai took them in, he rushed to the train to add coal, and led them to the train carriage! A group of people shouted and screamed in, and after a while, the train began to move from slow to fast!

The children shouted as they watched the speeding train! Running around in the carriage, happy like something......

Li Tai came back to see Cheng Hong grinding charcoal, and consciously picked up the tool to grind saltpeter! Li Tai asked here, "Can this thing be done?"

Cheng Hong replied casually: "You remove that word!" Can it still be done? It can be done! Absolutely! ”……

Li Tai is full of doubts and distrust of this gunpowder! After grinding for a while, I asked Cheng Hong to match it! Cheng Hong said: "That's it, I didn't show my father what I went to the experiment!" When the time comes, let's do it in a hurry?

Hurry up and I'll do more here at once! I'm not going to grind this thing with you here next time! It's a reward for your train research these days! Besides, all science has to endure loneliness! You can't hold it steady for a while? How can you study more advanced things in the future? ”

Li Tai finally stopped nagging! Grinding gunpowder with Cheng Hong!

Here, the two Li You brothers and the children have also made enough trains, and when the coal is added, everyone gets off the train and goes home!

When he walked out of the door, Li Yu called Li You: "Fifth brother, have you found it?" People who work here sweat very easily! ”

Li You said: "Of course, didn't you look at those big stoves!" The molten iron is flowing, and I feel flustered from afar! ”

Li Su said: "Then fifth brother, is the water in your gourd running out soon?"

Li You said: "Yes! What's wrong? Are you thirsty? ”

Li Su shook his head: "Fifth brother, you said that we should take a bucket to boil red dates and honey water and then sell it here, can we sell it?"

Li You patted his head: "That's right! The craftsmen inside brought water, but the merchants' guys didn't! After we boil it up, we will have a big bowl of money, and if we boil more, will we have credits? ”

"You can also pull up small stones and two dogs! It's more difficult for both of them at home! If you can pull a handful, Zi said: Fulfill the responsibility and help the world! They are all the children of the Emperor, right? ”

"Yes! Oh, yes! But it's better for the two of us to try it first! If the achievement is dry! If it doesn't work, let's not pull people! ……”
