The Rise of the European Emperor
The first thousand and fifty-seven chapters are too beautiful
When Mechio met his behind-the-scenes big boss with anxiety and excitement, he saw Marin smiling like a chrysanthemum. Of course, unlike the chrysanthemum that Maximilian I smiled, the chrysanthemum that Maximilian I, who was almost 50 years old, smiled was an old chrysanthemum, the kind that was about to wither. And Marin was still a handsome young man, and the one who laughed was a daisy...
"Hey, our boss's boss has seen it, why is he smiling so wretchedly? It seems that he owes a lot of money... No, isn't it said that he is one of the richest nobles in Europe?" Mechio said Confused, and even suspected that Marin in front of him was not Marin. However, Marin was wearing exquisite armor with the family emblem and was still sitting on the main seat, which most people would not dare to sit in. In this era of strict hierarchy, people will die if they wear clothes and sit in disorder.
"Mezio, the manager of the Florence branch of the Italian branch of the North Sea Chamber of Commerce, has met the owner!" After finishing speaking, Mezio bent down with a flattering face.
It stands to reason that Marin is just his boss, and he is not Marin's slave, so he doesn't need to be called master. Even when Kahn and others served as Marin's attendants, they never called the master (or so). Therefore, this guy is definitely a sycophant who is flattering to the extreme.
Suddenly, this scene filled Marin's mind - a coated slave with a tail of money behind his head knelt down in front of a Baqi boy and said meanly, "The slave has seen the master!" "...
For no reason, Marin suddenly felt disgusted. However, thinking of the sulfuric acid brought by this product, Marin couldn't control his smile immediately. Because, with all this sulfuric acid, he didn't have to worry about being unable to break through Siena's iron city gate.
So, Marin chatted with the sycophant Mezio in a pleasant manner...
Through some conversations, Marin learned that the sulfuric acid that Mechio escorted this time was the output of sulfuric acid produced by several alchemists in Florence in three months. It is dilute sulfuric acid with normal concentration. The reason for using clay pots instead of oak barrels is because sulfuric acid will corrode oak barrels. However, dilute sulfuric acid is also sufficient to dissolve the iron gate. If it is replaced with concentrated sulfuric acid, it will not be able to dissolve the iron gate. Because concentrated sulfuric acid will form a protective film with iron. Marin was even thinking—is it necessary to collect hydrogen to make a hydrogen balloon when dissolving the iron gate with dilute sulfuric acid?
Then, Marin didn't bother to pay attention to Mechio, and after promising to promote him and rewarding him with 500 gold coins, he sent him back to Florence.
After sending Mechio away, Marin happily returned to the city of Siena with the army and the carload of 100 clay pots of dilute sulfuric acid.
That night, taking advantage of the enemy's inattention, Marin arranged for one of his trustworthy special forces members (this tactic is also a secret) to hold a clay pot of dilute sulfuric acid, avoiding the sight of the enemy on the top of the city, and quietly touched the tin In front of the big iron gate of the northwest gate of Jena. Then, the soldier carefully picked up the clay pot and poured the dilute sulfuric acid in the pot towards the big iron gate of the northwest gate of Siena...
But what surprised the special forces soldier was that the iron door was not dissolved into a big hole as Marin said, but flowed down the iron door, causing slight corrosion to the bottom of the iron door. However, the effect is not too obvious. According to this efficiency, even if the 100 cans of dilute sulfuric acid are used up, the big iron gate will not be corroded...
So, the special forces member immediately went back to report the unfortunate news to Marin...
"What? The corrosion rate is very slow? And it all flowed to the ground at the bottom?" Marin was taken aback—is his plan going bankrupt?
"Yes, this kind of acid can't stay on the outside of the big iron gate at all. Once splashed on it, it will flow down the smooth surface of the city gate. Even at the bottom where the acid pools, it seems that the corrosion rate is very slow."
"The corrosion rate is very slow?" Marin thought for a while, and then suddenly realized...
"My brain, my memory!"
Marin suddenly remembered that in his previous life, the chemistry teacher once said,
To produce hydrogen in the laboratory, metal zinc is generally used. This is because the activity of zinc is much higher than that of iron. It is feasible to react with iron and dilute sulfuric acid, but the speed is very slow. Therefore, in order to show the phenomenon of generating hydrogen, the reaction of highly active zinc metal with dilute sulfuric acid or dilute hydrochloric acid is generally used to produce hydrogen, and the process of rising bubbles can be seen clearly. If iron is used, it seems to be much slower.
Moreover, pouring dilute sulfuric acid on the large iron gate is completely different from putting iron in dilute sulfuric acid to react. Soak iron in sulfuric acid, the contact area is sufficient, even if the speed is slower than zinc, but the effect is obvious after a long time. However, pouring dilute sulfuric acid on the iron gate is different. First of all, the iron city gate is erected. When dilute sulfuric acid is poured on it, it will not stay on the gate at all, but will flow down the gate to the ground. Before I had time to slowly contact and react, it landed on the ground. In addition, the reaction speed of dilute sulfuric acid and iron is not fast, which is a waste of sulfuric acid.
In addition, the Siena people are rich, and the iron city gates they made are thick enough. If you want to corrode the iron city gate with these 100 cans of dilute sulfuric acid, it seems that the feasibility is not high...
Also, Marin remembered again—it seems that even if zinc metal was used to produce hydrogen in the previous life, zinc was ground into zinc powder in order to increase the contact area as much as possible. If it is a whole block, it will be much slower. Because, if you want to corrode the metal inside, you have to corrode the outside part first...
Iron does not react quickly with dilute sulfuric acid, plus it is a whole piece of large iron gate, and the iron gate cannot be thrown into the pool of dilute sulfuric acid... Therefore, it is very difficult to corrode the large rear-facing iron gate with dilute sulfuric acid. It did it... At least, this carload of dilute sulfuric acid is not enough...
In addition, Marin also thought of a very serious problem - even if he could corrode a big hole in the heavy iron city gate, stuffing it into a gunpowder barrel would not destroy the city gate...
why? Because the iron city gate and the wooden city gate made of oak are not the same thing...
Generally speaking, if it is a wooden city gate, as long as a hole is made in the gate and a gunpowder barrel is inserted, the gate can be blown up and a road into the city can be obtained.
However, it is the oak city gate that is easy to be destroyed by bombing, and the road into the city appears. But now, the current city gate is an extremely thick iron city gate. Even if the buried gunpowder barrel explodes, it may not be able to blow open the thick steel city gate. If the city gate can't be blown up, what's the point of corroding the iron city gate into a small hole that can be stuffed into a gunpowder barrel?
Even if the hole corroded on the big iron gate happens to be the location of the city gate lock, it is useless, because during the city's offensive and defensive battles, the city's city gate holes are often blocked. As long as the city gate itself is not blown up, the city gate hole that has been blocked for a long time may not be completely blown open... So, the idea that dilute sulfuric acid can destroy the thick iron city gate before is too beautiful... …
