This "deputy commander of the Tianjin Guard" took Zhang Kangning and me with him, and at the same time, several thousand cavalry also lifted the siege and returned to their station.

We rode all the way, galloping, and kept changing horses at the post station on the way.

Fortunately, I also learned to ride a horse in Chang'an, so I was not ashamed.

At dawn, the fiery morning sun and the towering Yanjing appear on the eastern horizon at the same time.

Yanjing people all say this: After God opened the world, he traveled everywhere. He flew through the clouds and came to the north. He looked at the endless land of North China and was full of joy. He decided to build a city on it for the royal family he had just created. He raised his left hand, and the boulders of Mount Tai in the east, Mount Hua in the west, Mount Heng in the south, Mount Heng in the north, and Mount Song in the middle flew into the sky and came to the top of Guanzhong. He raised his right hand, and countless stones were automatically cut, turning into neat stones, beautiful sculptures, and these stones slowly fell to build the great Beijing Yanjing.

The walls of Yanjing are not as high as those of Luoyang, but they are not low either. There was no moat under the city walls, but all sorts of pillboxes, barbed wire, tunnels, boulders.

We went around from the labyrinthine path to the gate of Yanjing City, the big iron gate was the same as the gate of Tongguan, and the city gate slowly rose in a roar.

We entered Yanjing City.

Yanjing is the least populous of the four capitals, but it is also a megacity with a population of several million.

To the east of it is the East China Sea, the other three sides are guarded by forty acropolis, and to the north there are Yanshan, the Great Wall and Shanhaiguan.

In fact, it is a military city, which can control the grasslands of western Liaoning and eastern Liaodong in the north, Taihang Mountain in Shanxi in the west, Qianli Plain in Hebei in the south, and expeditions to Donghai Province in the east (although it is not known where Donghai Province is outside, it is written in ancient books).

Yanjing is similar to Luoyang, and she also has some in Luoyang, such as the palace area, the scholar area, the civilian area, the untouchable area, the industrial and commercial area, the manufacturing area, the entertainment area, and so on.

As a result of the coming war, there were more people inside and the atmosphere was even more tense.

Zhao Zhengbao is really unkind, his governor's palace is located in the emperor's Yanjing Palace.

The Yanjing Palace is almost the same as the old palace in Chang'an County, just as magnificent.

I was carefully searched and the vials were confiscated.

I had to tell them to keep it, and then I walked into the Yanjing Palace and walked towards the Prayer Hall, where countless guards stared fiercely along the way.

The prayer hall is the main hall of the Yanjing Palace, and the Qixia Hall of the Imperial Palace has the same pattern, and it is Zhao Zhengbao who sits on the dragon chair of the court.

At a glance, he looks very similar to Zhao Zhengbao, but not him.

I met him at Dongfang Mingyue's wedding three years ago, and I have a good memory, that person is very similar to him, but it is definitely not him.

"Zhao Zhengbao" on the dragon chair said: "You come ......"

I immediately interrupted him: "I'm too busy to play with the imposter." I want to meet the real Zhao Zhengbao. He had to understand that every minute he came every night, his people would die a bunch more. ”

After a moment of silence, a person walked out of the screen behind the court, tall, with a full beard, it was the real Zhao Zhengbao, which was a little different from what I saw three years ago, and looked a little ferocious.

He paced over and asked, "Who are you?" ”

I said, "Yes, I am God." ”

Him: "Don't be clever with me, I'm busy too, be careful that I drag you to feed the dogs!" ”

Me: "You bunch of waste, two rivers of 600,000 square kilometers, more than 500 million people, and two capitals in hand, were beaten like lost dogs. I can't even stand it. ”

Zhao Zhengbao shouted: "Someone, cut him!" ”

I waved, "Wait!" ”

He laughed: "I thought you weren't afraid of death." ”

Me: "I'm really not afraid to die, I'm afraid that I won't be able to teach you fuel and explosives before I die, and I'm afraid that I won't be able to help you." ”

Zhao Zhengbao continued to laugh: "Haha, who do you think you are?" Is that kind of technology you can have? Wait, who are you? ”

I said, "Well, I'm a scholar from Hebei Province, and I've developed the technology to make fuel and explosives. Now that the court has no way, and you are powerless to resist, I have decided to dedicate this technology to you. ”

He looked at me coldly.

There are dozens of high-ranking officials from Hebei standing in the court, just like the court of the imperial palace, but this is a smaller court.

Someone inside said, "Fart! Can we not know the people of Hebei, why haven't I seen you! This man came from the south with so many weapons, and he must have come from the imperial court to assassinate the commander. ”

I said, "My family used to be a Dashi clan, but it's just gone, of course you don't know." I have been living in seclusion on the Taihang Mountain, and this war was forced out. Can't I contribute something to my hometown? ”

More people began to ask me about the details, let me tell my father, my grandfather and even my ancestors for dozens of generations, and ask me all kinds of customs and customs.

I'm too lazy to say — in fact I haven't made it up — that too much is lost.

I looked up at them with disdain.

I said, "I came to help my own people, but I didn't expect to meet a group of dogs biting Lu Dongbin." ”

More people said, "Kill it." ”

Zhao Zhengbao also said: "It's okay to kill it." Someone, dragged out and cut down. ”

When a guard comes, they're going to pull me away.

Zhang Kangning was even ready to make trouble.

I yelled, "Wait a minute! If it were you, I'd let him try it and see if he could do it! ”

At this time, a man in his forties next to Zhao Zhengbao stood up and said, "Why did this guy come here to find death?" Let him try it once and see what kind of medicine is sold in the gourd. ”

Zhao Zhengbao touched his chin and squinted at him, that person obviously had a lot of weight in his heart.

I said, "I don't think you have a drop of gasoline, and this battle is still a hair!" Give me a barrel of soybeans and watch me turn a barrel of gasoline for you! ”

The staff member continued to say to Zhao Zhengbao: "Let him try, if he can't kill again; If so, this battle will be fought. ”

Zhao Zhengbao: "Everyone step down!" ”

All the officials stepped back, but the staff member still followed Zhao Zhengbao's side.

Zhao Zhengbao: "I'll give you a bucket of soybeans to try." ”

Me: "The potion I invented was confiscated by your guards in front of the palace, and I'm going to use it to 'turn stones into gold'." In addition, you will need some boiling water, ice cubes, various glass bottles, glass tubes, a thermometer and, of course, a bucket of soybeans. ”

Zhao Zhengbao: "Toss as you want." ”

I was tossing in the open space in front of the prayer hall, next to a circle of Zhao Zhengbao's guards, and he himself was looking at me from afar.

I've done petrol many times at the Royal Arsenal, but the process there is fixed, with all sorts of special instruments and special ingredients.

It's too simple here, so I can only adapt it to local conditions and give full play to my imagination. I control the temperature with 100 degrees of boiling water and zero degree ice water, and weigh the volume in various glass bottles. Soon the bucket of soybeans was turned into a barrel of mixture, and when it was settled, there was gasoline on top, water in the middle, and dross on the bottom.

I put gasoline in a keg and said to the onlookers, "This is gasoline, see for yourself." ”

The people on the side sniffed it, they took some more and lit it, and everything was like gasoline.

In the end, they brought a car with hemp rope, and sure enough, they had no gasoline at all.

They filled the barrel with liquid into the tank, and the car started and drove perfectly, which confirmed that it was indeed gasoline.

Everyone looked shocked. Because they have always been told that gasoline is a gift from the gods to the royal family, a sacred thing, and people can only dig it out from under the ground of the palace. But the man in front of him actually made gasoline out of a bucket of beans!

Zhao Zhengbao and the staff came to me.

The staff member said to the people around him, "Go down." ”

When there were only four of us left, he just circled around me, laughing as he walked, and I felt furious in my heart.

Suddenly he laughed and said, "Ten years, ten years!" When I left ten years ago, the inner court was fighting with the outer court; Ten years later, you're still fighting with the outside world! You really don't want to break the Ming Dynasty. I was trying to bribe the people of the inner court so that they could say good things in front of the emperor, but I thought that the inner court was in charge of printing money, so why would they care about money, so they didn't go. I didn't expect you all to come by yourself. Ha ha. ”

I had a feeling before, and now I have finally confirmed that this person is Ma Xingcai, the former imperial official of the inner court, the former prime minister's military advisor, and now Zhao Zhengbao's military advisor.

He said, "What Hebei Shi clan! You were sent by the Inner Court. I've seen this 'soy enzyme' at the Royal Arsenal, and you're doing exactly the same thing as theirs. You still brag that you invented it, and you can't invent it if you are given 10,000 years! ”

He's said it's all like this, how else can he pretend.

I had to say, "Okay, I'm from the inner court." It seems that you are Ma Xingcai? Liu Xingchao, the head of the inner court, specially instructed me to say hello to you on his behalf. ”

Zhao Zhengbao's eyes widened: "Liu Xingchao? It was he who flattened Hanzhong County! ”

I said, "What can he do, the former governor Li Yongfu ordered him to do it, does he dare not go?" If he wants you to bomb, do you dare not go? Besides, in the end, he helped you kill Li Yongfu and avenged your whole family. Li Yongfu did all this, but he died a long time ago, and all this was over a long time ago. ”

Zhao Zhengbao lowered his head and did not speak.

I continued: "Now that the emperor and the prince are bastards, and the outer court is also taking advantage of the fire to rob, and the people are suffering, your life is not easy, and the life of the inner court is not easy, so we decided to help you deal with those bastards. We just want to make everything stable, everyone can live in peace, and no one is fooling. ”

Zhao Zhengbao shook hands with me, and Ma Xingcai also came over to shake hands with me.

Zhang Kangning also shook hands happily.

Everything is in order.

The two of us returned to Tianjin Wei and then entered Yanjing City.

We are stationed in the Guanfu district of Yanjing.

Surrounded by a large number of Zhao family's pro-army, their equipment is not bad, and they also have submachine guns. The per capita number of weapons in the Hebei army is very low, but the equipment of Zhao Zhengbao's pro-army is not below us.

It seems that they still have a hand on us.

Ma Xingcai is in charge of receiving technology.

I must admit that the people from Wenju are really powerful. Ordinary people in Daming are basically a mess of brains, and if you want them to learn technology, the only possibility is to die and be reincarnated. Ma Xingcai is very smart and a very fast learner, he is in his forties, and he still chases me like a primary school student to ask me questions.

I wanted to hide some of the principles and just give him the fixed process, but he kept asking me questions like "why this is happening", "what if I don't do this", "what will happen if I change it to that", and so on.

Still, I kept a few hands on it to save them the real technology.

I gave him the "bean-loving mushroom" so that he could produce the "legumase" himself and then make gasoline using the method I taught him.

I taught him how to make gasoline in one day.

The minerals in Hebei are different from those in Gyeonggi, so I asked him to bring samples from all over Hebei.

After many days of screening and testing, it was finally successful.

The explosives we make are not pure, but they are a hundred times more powerful than black powder.

With explosives, they quickly made all sorts of grenades, mines, bombs themselves, and also shells and bullets.

Their products are not very powerful, they are also unstable, and they often blow themselves up, but they are better than broadswords and spears, right?

Zhao Zhengbao coerced a large number of Central Plains troops and Central Plains people from the Central Plains, plus his people, all of them began to carry out military production, day and night, the entire Yanjing was full of black smoke and white smoke, and the poisonous gas choked the nose.

At my suggestion, Ma Xingcai also carried out a technical blockade.

Each group only does one job, such as crushing ore and diluting nitric acid, and no one is allowed to inquire about other people's affairs, and violators are executed. In this way, except for a few core people, no one knows what they are doing.

Now, explosions are frequent in Yanjing City, and flames and smoke are everywhere in various districts, all caused by operational errors, such as throwing nitric acid barrels from high places, or people smoking in front of oxygen tanks, or using wooden barrels to hold concentrated sulfuric acid.

As long as it is a mistake, they have to make it again, and they have to try all kinds of mistakes that I can't even think of.

But it can't be so much, no matter how much it explodes, it will have to be produced, and no matter how many people die, it can't be stopped.

Soon they produced mountains of gasoline and ammunition.

Finally, with my own efforts, in one month, I brought the Hebei Army from the era of cold weapons to the era of hot weapons.

They're going to deal with the Royal Army's broadsword and spear, you can imagine that.
