Yuan Dadu, the palace Qingning Palace.

Fan Chang, a scholar of the Ming Dynasty, stood proudly in the hall, facing the surrounding ministers of the Yuan Dynasty who were either fierce or silent or shouting and shouting to kill or whispering, and waited for a moment, and said loudly to the Supreme Emperor on the throne: "Your Majesty, the three-day period has arrived, if there is no decision, the foreign minister will ask for resignation today." ”

Three days ago, Fan Chang, who was ordered to send an envoy, arrived in the capital of Yuan and proposed a series of armistice conditions to Emperor Zhizheng in court.

To sum up, there are three things: dedicating the soil, calling the ministers, and paying tribute.

Fan Chang brought a message from Emperor Hongwu of the Ming Dynasty, saying that the two sides had been fighting for a long time, and the people and money had been lost, so he proposed a plan to suspend the exchange of troops.

The first condition is that the Yuan Chamber must not only give up all the land that the Ming Dynasty has actually occupied, but also order Li Siqi and other troops in Guanzhong, Liang Wang in Yunnan and other troops to surrender to the Ming Dynasty and take the initiative to donate the corresponding territory.

Again, just like the Song Dynasty did to Liao and Jin back then.

Bow down to the vassals and pay tribute every year.

Lao Zhu did not hide his intentions from this loyal minister who had followed him for many years, this time the envoy was to drag Emperor Zhizheng and prevent the Yuan court clan from fleeing north, but, even so, hundreds of years later, the Han family Erlang was able to put forward such conditions to the Mongolian people who had destroyed the Central Plains countries, Fan Chang felt that it was worth his death.

but he did not die.

The first time it was played, it was also in this Qingning Palace, many Yuan court courtiers shouted at him, and some Confucian ministers who were loyal to the Yuan family wept bitterly and asked Emperor Zhizheng to kill Fan Chang immediately, thinking that this was the Ming Dynasty's strategy of 'punishing the heart'.

If Emperor Zhizheng agreed to those conditions, the hearts of the Yuan family would immediately collapse, and they would be completely irretrievable.

However, Emperor Zhizheng did not agree to the shouting and shouting of his subordinates, but after playing the right game, in order to avoid Fan Chang and others being harmed, he specially sent troops to protect him.

Fan Chang gave Emperor Zhizheng three days to think about it.

Today is the third day.

This is already the twelfth day of the seventh month of leap.

Fan Chang was a civil servant, and he was not aware of the overall military arrangements of His Majesty the Emperor, but from the fifth day of the first month from Bianliang to today, only looking at the attitude of Emperor Zheng, he understood that he had completed his mission well.

On the throne.

Emperor Zhizheng, who was fat and pale, was obviously in poor physical condition, but as the longest-reigning emperor of the Yuan Dynasty, Timur, who had been on the throne for 35 years, actually understood everything in his heart.

Fan Chang came here, but it was just a delaying tactic.

According to the information obtained, the emperor of the Southern Dynasty, who was born in herding cattle and begging for food, was using troops against Timur and Li Siqi in Guanzhong at the same time.

However, are most of them capable of making trouble?

Nearly 100 years after the founding of the country, it is said that he is greedy for pleasure, but those courtiers, how can it not be so, where are there still the brave warriors of the ancestors?

At this time, if you can buy some time, then buy some time.

Speaking of this, I heard that the Ming army had taken Bianliang, and Emperor Yuan Shun had already moved the idea of a northern tour and made arrangements.

Present...... It seems, at least for a short time, there is no need to escape.

Therefore, Emperor Yuan Shun also made up his mind.

Drag!

On the surface, he agreed to the Southern Dynasty.

Emperor Zhizheng also fantasized that after suffering this humiliation, the grassland children would wake up, regain their strength, and turn things around.

Present.

In the face of Fan Chang's questioning and inquiry, his heart was full of indignation, and Emperor Zhizheng still had a calm posture on the surface, and said in Chinese: "Fan Qing, since the Southern Dynasty wants to negotiate peace, how can it be in three days?" There are many detailed rules here, and it is better to discuss them slowly! ”

When Emperor Zheng said this, the hall suddenly fell silent.

Fan Chang was also an accident.

This......

So...... Is it right in the middle?

Fan Chang received the order of Lao Zhu to delay as much time as possible, but he also knew that if he delayed for too long, when the Ming army came, he would not have time to escape from the city, and he would probably lose his life.

It's just that, although he understands, Fan Chang still makes a decision without hesitation.

Stay.

Talk!

……

Bianliang.

It's still in the col surrounded by mounds when the hot air balloon was released last time.

Boom –

Boom –

After two loud noises that caused a big earthquake to tremble, Lao Zhu, who was standing on the top of the earthen hill hundreds of zhang away, hurriedly raised the monocular in his hand.

I saw that the place where the explosion had just exploded, one large and one small, two earth pits.

I can't help but marvel in my heart.

The two earth pits were blown up by the same 10 catties of gunpowder.

Since it is a large and a small, two kinds of gunpowder, of course, are different, the one that blew up the big pit has white sugar added to it.

This is the result of Lao Zhu's recent efforts to squeeze out time to study the book "Chemistry" sent by his precious twenty-third grandson.

That kid is in Minnesota and has been writing all kinds of books.

I also said before that in order to avoid his distraction, there is a need for continuous improvement and revision, so I will not send it for the time being, but the uninterrupted correspondence, or letters, or logs, and what is written on a daily basis, are mentioned.

For example, in order to help Nahua Gao's son, he wrote a "Scientific Parenting Handbook", and Lao Zhu saw that Zhu Yuan mentioned it in the letter, and he was a little interested, but not much.

However, for the book "Chemistry", listening to the child's brief description in the diary, Lao Zhu specially instructed to send the book over.

Then, Lao Zhu only felt that the door to a new world had opened to him.

It turns out that everything in this world is just a combination of various basic elements.

It turns out that metal smelting is just a variety of so-called reduction reactions.

It turned out that the explosion of gunpowder was nothing more than an instantaneous gas expansion.

……

According to the random mention in the book, adding some sugar to gunpowder can enhance the power of the explosion, and the reason is also easy to understand.

The white sugar, mainly carbon, hydrogen, and oxygen, reacts together during the explosion of gunpowder to produce carbon dioxide and water vapor, both of which are gases, so the more gases, the greater the shock wave.

】

Lao Zhu asked the Zhengwupin Firearms Division, which was also inspired by his own treasure twenty-third grandson, to do experiments and see the effect.

At that moment, looking at the soil pit in the col that was obviously much larger than the next one because of the addition of white sugar, Lao Zhu gritted his teeth a little.

Ren is a magical secret ingredient, why didn't you offer it earlier?

However, Lao Zhu quickly discouraged himself when he thought about it.

Just like the various mentioned in the book "Chemistry", perhaps, for that child, it is just a commonplace after a few hundred years, since he is used to it, he doesn't feel special, nothing special, where can he think of offering it on purpose?

This made Lao Zhu a little curious.

I don't know how many 'commonplace' after hundreds of years are in the child's mind, anyway, in the past few months, Zhu Yuan has given many things, in Lao Zhu's opinion, are refreshing.

And then there's the present.

All the armies have been deployed, and the gunpowder and firearms division, which is planned to play an important role, have also been equipped with a full 60,000 catties, all of which have been quietly distributed to the armies.

Now, can't we take all that gunpowder back and mix it with sugar again?

Lao Zhu was thinking about it here, and the dusty firearms Shiro Zhonghan staggered up the dirt slope, and he couldn't wait to say without caring about the courtesy: "Lord, this is ...... This...... Why is it so amazing? ”

Reason?

Lao Zhu paused, still not planning to tell Han Yu.

It's not that you don't trust this courtier, but that you ...... It is also a concept that I got from my own baby twenty-third grandson, technical blockade.

Lao Zhu has quietly made up his mind.

Other mathematics, physics, and other disciplines may be widely disseminated, and this "Chemistry" must be strictly guarded. At the very least, before the various confidentiality regulations are clarified, they must not be casually known to outsiders.

In order to teach and disseminate in the future, it is also necessary to strictly select students from innocent backgrounds.

At that moment, in the face of Han Pre's inquiry, Lao Zhu did not answer, but said: "You don't need to ask more, as long as you study and study again, this ...... Proportion, add how much sugar, the most powerful? As he spoke, he motioned to the big pit in the col: "Just use this as an experiment and adjust the best way as soon as possible." ”

Comparative experiments are also casually mentioned in Chemistry.

It's very simple, but, like a layer of window paper, no one can see what is in the room if no one pokes it open.

Han foresaw that His Majesty the Emperor did not explain, did not dare to ask more, but just agreed.

Lao Zhu thought about it and said: "Give you five days, according to the ratio in the col, at least 5,000 catties will be transferred out and sent to Cangzhou as soon as possible." ”

Those that have been sent to the front line, Lao Zhu knows, it is not easy to change.

After all, there are still many ways to mix gunpowder, and Lao Zhu has specially understood it, not that it is enough to pour sugar into gunpowder. However, in the future, when attacking the city, the key part of blowing up the walls of the capital may be to use this newly blended white sugar gunpowder.

Regarding the explosion of the city wall, the Firearms Division has also made a detailed plan, as well as the suggestions of its own treasure twenty-third grandson.

In the future, when attacking the city, you must first fill in the trenches, and secondly, you have to dig pits in turn, and you need to stuff gunpowder into as confined space as possible.

Lao Zhu also understood at the moment that this was also to give full play to the maximum power of gunpowder, after all, the more airtight, what was it...... The gas expands, the greater the impact.

As for the dosage, I have tried it a few times, and combined with the specific details of the Dadu city wall, Lao Zhu feels that it is the safest to fill in 2,500 catties at a time.

Let the firearms department urgently allocate 5,000 catties, which can be used twice.

After the order, Lao Zhu asked Han Pre to re-experiment and compare twice, both of which were one large and one small.

Because he understood the truth, he repeated it several times, and Lao Zhu didn't look at it anymore, and there were still many things to deal with in the camp.

Back in the camp, it was already evening.

It is the fifteenth day of the seventh month of leap.

First saw the news sent by Fan Chang from Dadu, Emperor Zhizheng actually wanted to talk to him about the details, which made Lao Zhu both surprised and not surprised, perhaps, he also wanted to drag it out.

In addition, there are two portraits.

The latest sketch portrait of Emperor Zhizheng's father and son, which was made by a painter who followed Fan Chang to Dadu, confirmed that there was not much difference from the portraits that had been distributed to various armies, and Lao Zhu put his mind at ease.

Explain the messenger, let the other party return to Dadu overnight, and send a message to Fan Chang, Lao Zhu continued to deal with official business while eating dinner.

There is also news from the state.

Everything is ready, only a southeast wind is owed.

It's also frustrating.

In this battle, time is really important.

Laizhou can't wait for the southeast wind for a day, and the armies can only wait patiently.

Lao Zhu also asked whether it was feasible to row through the bay purely by manpower?

A: Yes.

The problem is that this will be very slow, so it may lead to a result that the matter has been exposed before the army has landed in Tsogu. Once the news is transmitted back to Dadu too soon, it will only increase the variables.

Therefore, it must be a raid.

Waiting for a strong southeast wind, it is best to send hundreds of large and small ships to the port of Zhigu within one day, no more than two days at most.

According to the plan of Laizhou, when the time comes, regardless of the ship's grounding, it will land as soon as possible and go straight to the northern passes.

The matter was found again, the news was sent to Dadu, it took a day, Emperor Zhizheng got the news, under normal circumstances, it is unlikely to escape decisively, as long as it is delayed for a day, even if the Chang Yuchun cavalry has not taken the passes such as Juyong Pass, at least many passes have been blocked.

Then, at the same time, the infantry army that rushed from Cangzhou and Zhigu to Dadu gathered under the capital for three to four days, planning to surround Dadu with 200,000 troops, and Emperor Zhizheng would also be unable to fly.

After going through the overall plan again, even if he understood the variables, Lao Zhu still looked forward to it more and more.

There are even plans to hold a festival tomorrow.

Sacrifice to the gods of the four directions to bless the army with all the best in this operation.

Then focus on the Western Front.

Feng Sheng is still in a stalemate with Wang Baobao, Lao Zhu is very satisfied, as long as it is stable over there, it will be a success.

And then there's Guanzhong.

Li Siqi and other troops were too unbeatable, and Fu Youde led the army to approach Chang'an for a time, but because of the established strategy, he had to take the initiative to retreat.

Lao Zhu has some regrets about this.

If you can take the old capital of the Han and Tang Dynasties in one go, it is also good. However, at the moment, it is still important to focus on the capital. If Chang'an is taken, the battle line will be long, and this side will not be able to replenish troops in time, which will be troublesome.

After dealing with the military, he turned to civil affairs.

On the Jinling side, there was a fire recently, but fortunately, it was put out in time and there was no major problem.

The explanation in the book is that it is due to a drought.

Lao Zhu was a little suspicious, but it was not suitable for in-depth investigation at the moment, so he just gave an order to Gong Weisi to carefully investigate to ensure that there was no inside information.

Then, there are natural disasters.

The drought in Huaidong is still continuing, and many places have determined that the harvest will be lost, and the imperial court has organized many prayers for rain from Zhongshu to the localities, but to no avail.

Lao Zhu already knew how the rain came from, and he also knew that it was unlikely to have an effect.

However, I still gave instructions and continued to ask.

After all...... You still have to believe in the things of gods and ghosts, otherwise, how did your baby twenty-third grandson come about? When asked tentatively before, the kid didn't deny that there was supernormal power in this world.

Then, in Suzhou and other places, excessive rain flooded fertile land.

It's only separated by a river!

Lao Zhu has a knot in Suzhou, compared with other places, Suzhou has the heaviest taxes, but since the matter has passed, after some consideration, it is decided to exempt it.

At the critical moment of the Northern Expedition, there must be no chaos in the rear.

Then, there is an impeachment.

The impeachment of his precious twenty-third grandson is a simple reason, and the accumulation is too much.

However, the local inspector of Songjiang Prefecture said that he hoped that the Yinghai Division would maintain the minimum guarantee policy for this year's summer flood and continue to purchase private fish next year.

Lao Zhu thought about it for a while, and directly asked people to send this impeachment to Mingzhou.

Let Zhu Yuan watch and deal with it himself.

For his baby twenty-third grandson, Lao Zhu is very relieved!
