Let me introduce you, this is my girlfriend, the Israeli boxing champion

"what is this?"

"According to El-Melloi II, this thing is called a sand table." Boudica's gentle voice was intoxicating, and it was impossible to tell how she looked when facing Nero.

"And what we are making now is a sand table of Constantinople and the surrounding terrain."

"And some models." Romulus said, holding the model of the soldier in his hand. He was responsible for the models of several Byzantine soldiers, while the model of the Ottomans was given to Leonidas I to complete.

"Is it a heavy workload?" The emperor looked eager to try.

"I think so. After all, we still have city walls, ships and several buildings in Constantinople that have not been built. Oh, by the way, don't forget the two castles, Alvin." Leonardo da Vinci, holding a cannon model in his hand, shouted to Alvin behind him.

"What castle? What color?"

"Those are the two castles that originally held down the reinforcements from the Black Sea. If I remember correctly, they were Jiarumeli Castle and Anatolia Castle."

"Oh my god, you guys managed to take down two of them in a row?" Alvin came in from the backyard carrying a box of materials. "When did it happen... Oh, Da Vinci, why do you have a cannon in your hand?"

"That's the Urban Cannon, Alvin." El-Melloi II showed a hint of helplessness. "By the time we got here, it was too late."

"I should have locked up that Hungarian craftsman." When he said this, Palaiologos was filled with regret. There was only one word: poverty!

"Let's not talk about this anymore. Your Majesty, do you want to do this together?"

"In fact, I have been waiting for one of you to speak for a long time." Constantine XI felt a little ashamed. "Because I thought I might slow you down..."

"Here are the Hagia Sophia and the Holy Palace in our charge, as well as the two castles and the banner that marks us, Your Majesty."

So, Constantine XI, who originally just came for a walk, threw himself into the struggle for the sandbox game (? ), and when everything was declared accomplished, he was amazed at the achievement he had participated in.

"This is really cool! Now you can see a lot of things at a glance!"

But when Basilius saw the valley part north of the Theodosian wall, he shrugged his face, and everyone looked unhappy when they saw that place.

"This is a good location," El-Melloi II said. "Constantine I certainly didn't expect this day to come when he founded New Rome."

The place they were talking about was the Lycus River Valley north of the Theodosian Wall. The terrain of the entire Theodosian Wall here was much lower, and it was the lowest point of the entire wall. Because of the existence of this river, Leonidas I and Justiniani often had headaches when commanding the soldiers to dig trenches.

And this was only the first weak point. When building the city wall, Romulus deliberately turned a corner at the northeast corner, where Blachernae Palace and Bracknell Village were located. In order to supply food production for the entire city, there was only one city wall in that area.

"I never expected to encounter such a situation..."

"And don't forget the most important point, everyone." Alvin placed the Urban Cannon outside the Theodosian Wall. "Can a wall built specifically for cold weapons really withstand an artillery attack?"

Everyone was silent. In fact, it was true. The Urban Cannon was not fatal because it exploded very quickly. The real threat was the continuous artillery attacks. They were like using ice to scrape the skin. It might not seem like anything at first, but scraping can really kill people. The final fall of Constantinople was also closely related to it.

"I think I can use magic to..."

"Teacher, don't forget Attila. If we really encounter a servant from the enemy force in the battle, it will be difficult for us to free up our hands."

At this moment, Alvin picked up a model of a city wall.

"So while there is still time, we have to solve this problem properly."

Chapter 062 "Constantine XI's Research Report in Chaldea"

"Look at what you said, Alvin. Can this be remedied?" Boudica was a little surprised. This was within her blind spot of knowledge.

"Yes, that's right."

On another table, Alvin spread out a piece of paper and drew a cross-section of the Theodosian Wall while discussing his ideas.

"The speed of a cannonball can reach 600 to 800 meters per second, which is incomparable to bows and catapults. The tall city walls of the Middle Ages had almost no resistance to high-speed cannonballs, and the higher the city walls, the more damage the cannonballs caused to the city walls."

“What does medieval mean?”

"This is a phrase I learned in Venice. According to that scholar, there was no strong regime to rule Europe in the Middle Ages. Feudal separatism brought about frequent wars, and the Catholic Church imprisoned people's thoughts, causing the stagnation of science and technology and productivity. People lived in hopeless pain."

"That's too dark." Constantine I muttered, and when he wasn't paying attention, Alvin secretly made a gesture to El-Melloi II.

"In fact, the French have already done this. They used 25,000 soldiers and 40 guns to destroy the weak Holy Roman Empire."

"That's not how you use 'Ferrara', Alvin," Da Vinci corrected, but she spoke the following words in a voice that only the Servant could hear.

"Falsification of facts must also be based on the Basic Law..."

Of course, Palaeologus could not hear Leonardo da Vinci's complaints, as his attention was completely attracted by the city wall on the drawing.

"In order to resist the impact of the shells, we have to lower the height of the city wall. At the same time, we have to use the demolished materials to increase the thickness of the city wall. A certain thickness of mud is also applied to both sides of the city wall to absorb the impact of the shells."

"Another solution is to replace the material of the chop wall with fired bricks and cover it with a mixture of mud and dead grass. This way, when the chop wall is hit by a shell, it will not produce a large amount of flying debris, and the safety of the defenders will be greatly improved."

"After all, we don't have many people." Alvin spread his hands. This was indeed a fatal flaw.

"If the city walls were lowered, wouldn't it be easier for the attackers to climb? Should we do this with ladders and other things?" The mayor of Constantinople was puzzled.

"The trench, how many meters long is the trench in front of the walls of Constantinople, Mr. Leonidas?"

"About four meters."

"Then we have to increase it to ten meters. Since the city wall has become shorter, we can only deal with it by increasing the depth of the moat. Oh, and the river valley can be used to draw water from the Licas River."

Alvin picked up his pen again, and this time he drew the fortifications.

"Boudica, how many guns do we have left?"

"Twenty-four doors."

"Let's dismantle a few carracks. The Venetians will back us up anyway." Basilius acted decisively and gave this order as soon as he returned.

When Alvin finished the painting, Constantine XI had already come over and was looking at the slope in front of the trench. He seemed to understand something.

“Excess dirt is piled here?”

"The shells fired by the artillery move in a horizontal or low-arc parabola, and the area below the city wall is a blind spot that a single artillery cannot reach. This is designed to solve the blind spot, Your Majesty."

With Alvin's vivid explanation, the two servants guarding the city had a deeper understanding of this.

"We have to reshape the ground outside the trench and build a gentle slope that gradually decreases from the inside to the outside. When the Ottomans attack the city, this gentle slope can consume a certain amount of their physical strength, and when they rush to the top of the gentle slope, they will face the muzzle of the artillery. Therefore, the closer they are to the city wall, the stronger the firepower they face."

"Of course, a castle cannot have only one cannon. In order to minimize blind spots, we have to consider the overall situation. The cannons are protruding outside the city walls. The protruding shape also allows the cannons to fire in multiple directions, so that the cannons can obtain more shooting angles. At the same time, several protruding bastions can cover each other."

"Low walls, deep trenches, defensive slopes and angular gun positions..."

The cards in Constantine XI's hand were much worse than those of Chongzhen, but even so, he fought to the last moment, unlike some guy who hanged himself directly on the old crooked tree.

Leonidas was a military expert indeed. He quickly realized the huge impact this new system would have on the defenders.

"In this way, only a small part of the defenders can rely on the castle to resist tens of thousands of troops. Through this relationship, the threat to the upcoming Ottomans can be greatly increased. If they still choose to set up camp in an area where archers cannot shoot..."

"Then let them have a taste of artillery!"

Constantine XI was extremely excited. This was undoubtedly an advanced idea. He insisted on Mourinho's defensive counterattack tactics of parking the bus. As long as the attacking side consumed too much manpower here, it would be his chance to regain the core provinces.

And he had not forgotten that the Mamluks and Karaman were already gathering their troops to attack the Pasha's territories in the rear, not to mention that he had the help of the Albanian commander who had won 13 battles and 13 victories...

In the words of later generations, it means "I am already considering the scenario of restoring the country."

"If you are not the future, Mr. Alvin, I really want to keep you here as the governor."

In just one morning, Basilius kept praising him, and Alvin had completely conquered the Roman emperor.

"But siege and defense are just two sides of the same coin. The two will never stay in the same position." As the "human body" of a villager, El-Melloi II quickly saw the shortcomings of the system described by his disciple.

In response, Alvin simply picked up the cup and drank the water.

"Unfortunately, we are the only ones who have the antidote at the moment."

"In that case, everyone, how about going to the palace tonight for the dinner?"

In a tavern next to Hagia Sophia, Basilius extended an invitation to them.

PS1: Li Shizhen - Li Yuanhao lied and swallowed 2215 needles

The passers-by who saw EDG were all suffering from brain congestion. They just wanted to give in.

As soon as he opened his mouth, it was the old Letme.

PS2: Su Mei has left OG, and that chef is coming back. I suggest you go to the hot pot restaurant to see if there is any news about an Australian chef resigning.

By the way, although Mr. Sai is a storyteller, he is still a good person. It's okay to have five nights of clouds.

So Brother Chen is still the best.

PS3: Judging from the situation in the last half month before the high school entrance examination, my sister’s school is also outrageous.

Chapter 063 From Sultan to Messenger

In the palace of Bursa in 1444, the 12-year-old Mamtim II sat alone in front of the window of his study, with the urgent secret letter from Varna on the table. "

His father, Murad II, whom he had just invited back in the name of the Sultan, died of malaria that broke out in the army. This was purely an accident, but he felt very guilty about it.

If nothing unexpected happens, he will leave Manisa, leave Bursa, leave the position of Pasha, and become Sultan again.

"Edirne..."

The voice was still very childish, but it already had a bit of dignity in it. Edirne was not only the capital of Ottoman Turkey, but also the place where he was born. Originally, he thought that he would have to wait at least another ten or eight years before he could return there.

"Please ask the teacher to postpone the Hebrew class in the afternoon," Muhammad said to the attendant beside him.

"......Sudan."

"what's up?"

The man in front of him was the son of a prisoner of war whom Murad II had met on the battlefield. He was also his classmate and good friend. His unnatural attitude naturally did not escape the eyes of Mehmed II.

"what happens?"

"There is someone outside the door asking to see you. He specifically asked to see you, the Sultan."

"Is this man crazy?" Mamtim was incredulous, but the servant's next answer surprised him even more.

"This happened ten minutes ago. He is already waiting in the hall now?" The attendant hesitated for a moment, and only continued after seeing Mamtim's expression. "He broke in alone. Many of us couldn't stop him."

"It seems that I have to go."

Any normal person would find it difficult to sit still when hearing about such behavior, and the young Mehmed II was no exception. But when he saw that man, he understood for the first time what the gap was.

"Hello, Mr. Mohammed bin Murad bin Mohammed bin Bayezid, or, Mohammed II."

An old-fashioned dark green suit, an unchanging and calm smile, and a hat that was totally out of place, this was Mehmed II's first impression of the prime minister Leif Lenore.

"What do you want to do here?"

"I want you to do something."

The man leaned back in his chair, speaking in a gentlemanly manner but speaking extremely nasty words, his face full of mockery and malice.

"I want you to pass on the Sultan's location to a man named Erdogan who is far away from you."

The Sultan, as well as the other guards and servants were all shocked by this man's outrageous remarks.

"You...what did you say?"

The Sultan wanted to scold him loudly, but when he thought of the man's fighting ability, he gave up the idea.

"Of course, I can, but I need to see a handwritten letter from my father, the former Sultan."

This is almost a fantasy. The dead cannot change the living world. But in response to this statement, Leif just smiled and took out the "handwritten edict" of Murad II from his extra-dimensional pocket.

"As to whether this decree is true or false, please let the Sultan himself judge for himself."

Mamtim went up to get the "handwritten note" in person. In his impression, there was no such person named Ralph Lenore around his father, but the change in his expression just now made him feel a little strange.

No, it can't be true. I am my father's only designated heir and the Sultan of Ottoman Turkey. I have nothing to be afraid of.

Young, you, the young Mehmed II opened the familiar envelope with his hands, and fear arose in his heart.

My son, Muhammad:

Long time no see, how are you doing in Manisa? The situation in Varna is not optimistic. The Crusaders have gathered nearly 5 soldiers and horses, led by János Hunyadi and the King of Poland. This battle is not optimistic for us. They have extremely strong combat effectiveness, especially the Polish Winged Hussars. I suspect that they only need people to completely defeat us...

The previous words all describe what happened on the battlefield of Varna, but this is actually nothing. What is important is what his father told him later. When Muhammad thought of this, he couldn't help but feel fear in his heart. This handwriting was undoubtedly his father's. In other words, this secret letter would determine his fate.

...My proud son, I think this decision may be a cruel thing for you, but for the sake of Ottoman Turkey and for you to have a good ending, I have to make this decision with great pain.

In the name of the Sultan, I deprive you of your status as heir and decide to train Erdogan as our new Sultan. Maybe you don't remember this name, he is...

He no longer wanted to read the rest of the content. His father's handwriting could not be false, and judging from the date, the secret letter was sent exactly one day before his death, so it had a unique propaganda effect.

"Your Majesty..." Some of the guards looked at Mamtim II who had fallen into silence. Judging from his dull eyes, they had already prepared for the worst.

"All this is just the mission of Lord Murad, Mohammed." Leif said playfully. Only he knew whether this secret letter was forged or not. However, seeing the look of the young Sultan, he suddenly felt that it might not be a bad idea to continue acting like this?

"...If it is really my father's order...I will accept it willingly."
