The Rise of the European Emperor

This time, Marin was more cautious and focused on safety. In addition to putting gas masks on the experimental soldiers, longer glass tanks were used. The notch of the glass tank is facing the iron door, but after the aqua regia touches the iron door through the glass tank, it will definitely corrode the gap and then flow down.

Therefore, Marin asked people to drop a bale of grass under the city gate first. In this way, even if the aqua regia flows to the ground, it will fall on the haystack. Not to mention the corrosion of aqua regia on the haystack, but the aqua regia must be stagnant by the haystack, and it will not flow everywhere, and it will not flow to the feet of the soldiers.

In addition, Marin put the experimental soldiers into shoes made of multiple layers of cowhide. In this way, even if aqua regia flows under your feet, it will corrode at most one or two layers. Because aqua regia is much less corrosive to organics than it does to metals. Just performance stained, up to burn the skin. Therefore, the soles of the multi-layer leather on the boat can protect the feet. Of course, you can't stand in the aqua regia for too long, giving the aqua regia enough time to corrode.

After testing, the soldiers in charge of the test were indeed successful. It didn't take long for aqua regia to corrode the iron gate and create a big hole.

Next, it's the blasting part. However, before the bombing of the door, the soldiers of the blasting team were also seriously afraid of the aqua regia on the ground and did not dare to go forward.

Then, Marin thought of a way...

He first made the Demoman wear a gas mask as well. Then, in front of the Demoman, send someone to sprinkle quicklime in front of the door. Quicklime is a strong base, while aqua regia is a strong acid. After acid-base neutralization, there is less danger on the ground.

Then, the Demoman went on, stuffing the powder keg into the large corroded hole in the iron door...

...

However, after a blast, the blockage behind the iron gate was blown away, but the iron gate remained standing...

Marin looked a little dumbfounded, then began to think...

After a while, Marin suddenly realized-

"I understand, even if the blocking material behind the iron door is blown up, the iron door will be difficult to blow up. Then, we corrode the door bolt part..."

Then, he started a second attempt. This time, he asked the soldiers not only to etch a large hole in the iron door, but also to make it corrode the bolt part.

In this way, when the large hole is corroded, the door bolt is corroded together. After the blasting again, although the iron door was not damaged, the bolt had been corroded, and the debris accumulated behind the door was also blown away. At this point, just let someone push open the iron door to get in...

Then, the demolition captain Doni Tserai proposed a new plan—corroding the shaft of the iron gate. In this way, without the door shaft, the iron door must have collapsed directly...

However, after testing, the effect of corroding the door shaft is not good...

It's not that the door shaft is difficult to corrode, but that after the door shaft is corroded, the blasting effect of stuffing it into the gunpowder barrel is very poor. Because the door shaft is located on the edge of the iron door, it is difficult to blow up the piles behind the iron door after it is stuffed into the gunpowder barrel.

Therefore, it is best to corrode the latch in the middle of the iron door. Because the door latch is located in the middle of the iron door, after inserting the gunpowder barrel, the piles behind the door can be pushed forward, which is more convenient. And blasting on the side of the door shaft at the edge can only blow up a small part of the accumulation.

In this way, the tactics to deal with Tiechengmen have been decided...

However, the height of the gates of the city gates is not the same in each city. If the wrong part is corroded, it is a waste of aqua regia. So, Marin sent spies and specially asked them to go to the target cities to conduct on-the-spot investigations, investigate the heights of the door latches in those cities, and bring back the recorded results. In this way, when you go to siege the city next time, you can directly corrode accurately according to the data...

...

While Marin was busy experimenting with how to corrode the Iron City Gate, a big event happened in Krakow, the capital of Poland - Queen Anne was about to give birth...

Anne has been married to Sigismund I for several years and is now 24 years old. Probably Sigismund I was middle-aged, and the sperm motility was not enough. So, Anne married for a few years and finally got pregnant.

And at the beginning of September 1512, Anne finally arrived due to give birth...

To witness this moment, King Sigismund I of Poland,

He specially rushed back from the battlefield of the Principality of Mazovia to witness the birth of his son.

...

It should be pointed out that before that, Sigismund I led an army of 15,000 people and was fighting on the front line with the Principality of Mazovia...

The Principality of Mazovia is a powerful principality in Poland with an area of ​​about 33,500 square kilometers, which is larger than the direct territory of the Jagiellonian royal family in Poland.

In terms of strength, the Principality of Mazovia is no weaker than the Jagiellonian royal family. Therefore, the Principality of Mazovia usually does not bird Sigismund I, the king. Moreover, people in later generations, the capital of the Principality of Mazovia, know - Warsaw...

That's right, Warsaw, the capital of Poland in later generations, is also the place where the "Warsaw Pact", which is as famous as NATO, was concluded. Now, it is the capital of the Principality of Mazovia.

The Principality of Mazovia is located in the middle reaches of the Vistula River. It is dominated by plains and is a very fertile agricultural area in Poland. Moreover, the Vistula River is the most important inland waterway in Poland. Just setting up a card to block boats on the Vistula River to collect taxes will bring huge benefits.

And the cause of the war between Sigismund I and the Duchy of Mazovia was caused by the Duchy of Mazovia setting up cards to block ships and collect taxes...

At this time, Krakow, the capital of the Kingdom of Poland, was located in the upper valley of the Vistula River. When Anne married Sigismund I, Marin promised to provide Sigismund I with at least 10,000 Ugrams (120,000 acres) of fertilizer every year. Then, help sell the food produced by the tens of thousands of Eugram's land in Sigismund I.

Because part of the secret estate land of Sigismund I is near Krakow on the upper Vistula River. Therefore, whether Marin transported fertilizer to the southern manor of Sigismund I, or Sigismund I transported grain from some southern manors to Marin's North Sea Country, the main route was through the Vistula River. of inland shipping.

It stands to reason that there are several vassal states on the Vistula River, and both grain and fertilizer ships must be taxed. But Prince Sigismund was the king. After he came forward to greet him, most of the lords agreed to release Sigismund I's fertilizer and grain ships duty-free. Only the Principality of Mazovia, ignoring Sigismund I's greetings, continued to collect the toll tax in its own way.

Sigismund I suddenly became angry - Lao Tzu is the king of Poland, and can you be blackmailed by a local lord? Then, he signed an order with a strong attitude, ordering that the Duchy of Mazovia would no longer levy a toll on the ships of the Jagiellonian royal family.

Unexpectedly, the Principality of Mazovia not only failed to carry out the order, but also seized several grain ships of Sigismund I in the name of "resisting the tax", and planned to confiscate the grain of these ships.

Sigismund immediately felt insulted, and then he sent a large number of troops to attack the Principality of Mazovia. On the surface, it was to "severely punish" the Principality of Mazovia, which did not respect the royal family. In fact, Sigismund I already had plans to annex the fertile Duchy of Mazovia...

Before Anne's due date, Sigismund I personally led an army into the Principality of Mazovia. Therefore, even though he heard that the second uncle's brother Beihai was in trouble, he couldn't help for the time being.

Because of the lag in the transmission of news, when the Beihai Kingdom was in trouble, Sigismund I had already led the army to the Principality of Mazovia, and was naturally unable to support the Beihai Kingdom.

However, after learning that Anne's due date was up, Sigismund I temporarily left the army and rushed back to Krakow...

After nervously waiting all night, in the early hours of the morning, a baby's cry finally came out from the delivery room - "Wow"...

...

Sigismund I was excited and a little nervous at the same time. He asked between them:

"Is it male or female?"

If the husband of later generations asks such a question in the first sentence, the wife will definitely be angry - why don't you ask the old lady first?

But in this era, for a king, it is the most correct operation to ask "is it a man or a woman" first. Because, this is about the inheritance of a royal family...

"Congratulations, Your Majesty, you are a prince!" The midwife's voice came from the room.

"Wow, it's a prince! Ah ha ha, I have an heir!" The 45-year-old Sigismund I jumped up with excitement.

In the room, Annie was also very happy after hearing that she had given birth to a son. However, she was too tired, after all tossing all night. So, she fell asleep quickly...

In the afternoon, when Anne woke up again, Sigismund I was walking around happily holding her son, and clumsily singing nursery rhymes to coax her son.

Seeing Anne wake up, Sigismund I shook her hand and said:

"Good work, Annie!"

Then Sigismund I asked again:

"What do you think the child's name would be? John? Charlie? Louie?"

Annie burst out laughing:

"Haha, I heard Brother Marin say before, these names are all bad. Just call these names on the street, and a group of people will answer you. I don't want my son's name to be so old-fashioned and have the same name as so many people!"

Sigismund I suddenly felt a little embarrassed, he was an incompetent named...

"Then what's your name?"

"What about the name Marin? Marin is the male name of my mother Mary. Besides, my brother is a great hero. My son will also learn from my brother and become a great hero in the future!" Anne didn't know yet, his great hero My brother has already "had an accident". This is Sigismund I deliberately blocked the news in order to prevent the pregnant Anne from being too sad after hearing the bad news and affecting her body and affecting the pregnant child.

However, fortunately, Sigismund I did not have too many taboos. Seeing that his wife likes it, and Marin can indeed be called a hero. So he recognized:

"Okay, let's call my son Marin! My son, the crown prince of Poland and Lithuania, will be called Marin from now on!"

Early the next morning, Sigismund I summoned his ministers, announced the birth of Prince Marin, and announced that Prince Marin was his heir. However, whether Prince Marin can eventually become the king of Poland still needs to be confirmed by the Polish House of Peers. This fucking king election system, that's how it is stipulated. Therefore, Sigismund I can only declare that Prince Marin is his heir, but cannot publicly declare that he is the Prince of Poland...

Of course, the Polish nobility could not elect randomly, and could only elect within the Jagiellonian royal family. Otherwise, it will be messed up. This is also the difference between Poland and Germany - the election of the German emperor is a random election, and anyone with strength can enter. The Polish king election is based on blood, and the royal blood is given priority. Unless the royal family is extinct, another choice will be made. Generally, the son of the king is the candidate, but if you offend the nobles too hard, it is easy to lose the election. This regulation is also to protect the interests of the nobles and avoid the emergence of kings who hate the nobles...
