The Cold War, which lasted for months, returned to its original state in an instant, as if it had never happened.

The monetary reform was still going on unhurriedly, and when Leng Feng bought a few pigs, but the butcher found him a new copper coin, he knew that the monetary reform was almost coming to an end.

The bank can be said to have contributed to such a smooth monetary reform.

The strong reputation of the merchants of the Tang Dynasty made Leng Feng willing to take the risk of allowing wealthy merchants from all over the country to participate in the construction of the bank.

Facts have proved that their credibility is indeed strong, and there has been no fault in various places until the handover of such a large amount of funds.

The bank's current credibility is not only due to the establishment of a bank in Chang'an, but also to the credit of those businessmen.

Let the soldiers of the Dragon Tooth Army carry the pigs in a large carriage, and Leng Feng went to the Academy of Literature.

Buying pigs is a precedent set by Han Chongwen, originally the Academy of Literature only had the opportunity to eat meat once a week, but Han Chongwen saw that many children from poor families were hungry for meat, so he used his own money to buy meat for the students, turning once a week into twice a week.

The gentlemen of the Academy of Literature, it is their turn to pay the money this time, and Leng Feng is also a guest teacher, and he also has his share in buying meat.

Let the soldiers of the Dragon Tooth Army bring the meat to the canteen, and Leng Feng will go to the scientific research institute to see Li Tai's progress.

It stands to reason that he has drawn a sketch of the seeder, so Li Tai won't be unable to get it!

The land in the compound of the scientific research institute is now full of ravines, and Li Tai and his men are leading a cow and letting it pull the machine behind.

It was the seeder drawn by the cold front.

However, compared with Leng Feng's sketch, Li Tai's one has been significantly improved, and training wheels have even been added on both sides to keep the seeding box moving forward in a straight line.

Seeing Leng Feng coming, Li Tai ran over with a smile and said, "Master, how do you see the improved version of the seeder I made?" ”

Leng Feng nodded, "It's very good, at least it's improved a lot, but unfortunately there is no chance to experiment, it's not that if you get the seeds down, even if it's a success, the depth of sowing is also very important." ”

Li Tai had been taken by Leng Feng to farm before, and knowing this, he nodded, "Wait for next spring ploughing, I will definitely make this machine perfect by farming." ”

Leng Feng circled around the planter and didn't notice anything wrong, but his eyes were drawn to something under the tree next to him.

It was an iron pipe, and the iron pipe was not surprising, although Tie Sheng couldn't get a standard iron pipe thread or anything, but it was no problem to get a similar one.

The important thing is that the section on the iron pipe looks like a fuse.

What is it?

Leng Feng walked over, picked up the iron pipe and looked at it.

The iron pipe was covered with a layer of tissue paper, and Leng Feng, who had played with fireworks, did not reach out to poke it.

"Is this firework?" Leng Feng asked Li Tai.

Li Tai walked over, and after seeing what Leng Feng was taking, he said, "This is something that Zhang Zhongqing has made up, saying that it looks very good at night, and it won't be fried, and it took me a lot of effort to ask him for one, and I haven't picked a name yet." ”

When did Zhang Zhongqing stop tinkering with murderous things and tinkering with this kind of fun?

With doubts, Leng Feng went to the Thunder Division.

Now the Thunderbolt Division has changed places again, moving to a deep mountain, and the main site is separated from the outside world by an iron chain bridge, as long as the iron chain is broken there, with countless gunpowder weapons, it can resist any attack.

This is the sequelae of Zhang Zhongqing's kidnapping, for the safety of gunpowder weapons, if he can go to the sky, Zhang Zhongqing will definitely get the lightning division to the sky.

After brushing his face and entering the Thunderbolt Division, Leng Feng saw the scene where everyone in the manufacturing department was stuffy and filled with fireworks.

Originally, he thought that Zhang Zhongqing was just playing around, but now it seems that it is not as simple as playing!

When Leng Feng arrived, the doorman must inform Zhang Zhongqing, so it didn't take long for Leng Feng to feel that there was one more person behind him.

Zhang Zhongqing said with a bitter face, "I know that King Wei will attract you when he takes away a firework, don't say that I am wasteful, it is the emperor who makes me do this." ”

Charcoal saltpeter is a little easier to get, and sulfur is a very rare thing.

Leng Feng shook his head, "I don't doubt you tinkering with fireworks now, what I wonder is why do you know the name of 'fireworks'?" ”

Every gunpowder weapon, like thunder, is the name taken by Zhang Zhongqing, if Zhang Zhongqing called the fireworks "stinky fart" Leng Feng is not surprised, it will be called fireworks directly, this is too coincidental!

Zhang Zhongqing smiled: "Do you remember the time when we drank too much last year?" When you were drunk, you said a lot, and said that my thunder and thunderbolts were like fireworks compared to real weapons. He also told me about the beauty of fireworks, hehehe. ”

Drunk people are prone to gaffes, and Leng Feng is no exception, he didn't expect that he had drunk too much, and he actually said so many things to Zhang Zhongqing.

"So what? What did the emperor ask you to make fireworks for? ”

Leng Feng felt that he needed to divert the topic, otherwise Zhang Zhongqing would definitely complain that he knew more powerful weapons, but he wouldn't tell him how to make them.

Zhang Zhongqing shrugged, "I said that it was ordered by the emperor, how do I know what to do?" Okay, okay, it's rare for you to come here, come with me to see my newly made hidden mine, let me tell you, as long as it's a jungle war, this hidden mine can definitely play a great effect."

Listening to Zhang Zhongqing's boasting, Leng Feng didn't need to look at it to know that what he got out was a bore mine, in fact, there was nothing magical, it was just to hang a line for the thunder that was pulled, and wait for the unlucky ghost to activate the grenade after setting it up.

Leng Feng dismantled this thing I don't know how much.

Sure enough, Leng Feng guessed exactly right, Zhang Zhongqing's hidden mine was a booby mine, and there was no technical content.

Looking at the complacent Zhang Zhongqing, Leng Feng reluctantly picked up a stone and activated the booby far away, and the dirt brought up by the explosion couldn't even reach his feet.

"If you want a yin person, you can also get a thinner line! It's so thick, I've found it from afar. Also, you can't make the line a little lower and cover it up with weeds. The most important thing is that you can make the fuse inside the thunderstorm a little shorter, if you are a person who is running, you will not be blown up by the thunder! ”

Zhang Zhongqing didn't care about Leng Feng's indiscriminate bombardment, he knew that no matter what kind of gunpowder weapon he made, he would get Leng Feng's advice.

After finding a thin line to create a new thunderbolt and rearranging it, Zhang Zhongqing asked Leng Feng, "That's fine!" ”

Leng Feng looked at it again before saying, "This is about the same, this can definitely kill a lot of people." But, then again, what exactly are fireworks used for? You really don't know? ”

Zhang Zhongqing looked at Leng Feng speechlessly, this guy thought he knew!
