Chapter 1057： Think too beautiful

When Meggio saw his big boss behind the scene with anxiety and excitement, he saw Marin who smiled into a chrysanthemum. Of course, unlike the chrysanthemum that Maximilian I laughed out, the 50-year-old Maximilian I laughed out of an old chrysanthemum, which was about to fade. And Marin is still a young man who is so handsome, and it is a daisy that smiles ...

"Huh, the boss of our boss has seen it, why is he smiling so languidly? It seems that he owes a lot of money to others ... not right, isn't it that he is one of the richest nobles in Europe?" Confused, even suspected that Marin was not Marin. However, Marin wears exquisite armor with family emblems and sits on the main seat. Most people don't dare to sit like this. In this age of strict hierarchy, it is mortal to wear clothes and sit on seats.

"Mezio, manager of the Florence branch of the Italian branch of the North Sea Chamber of Commerce, has seen the owner!" After that, Mezio bowed down with a smile on his face.

It stands to reason that Marin is only his owner, and he is not a slave of Marin, so he does not need to be the master. Even when Kahn and others served as Marin's servants, they never called their masters (this can also be called). Therefore, this product is definitely a flattering flatterer.

Suddenly, Marin made up the scene in his head-a coated slave with a money rat tail behind his head kneeled flatteredly in front of an eight-flag brother and said, "The slave has seen the master. "...

For no reason, Malin suddenly had a feeling of disgust in his heart. However, thinking of the sulfuric acid brought by this product, Marin immediately couldn't control it. Because, with these sulfuric acids, he is not worried about not breaking the iron gate of Siena.

So, Marin and Yan Yue chatted with Mechio as a **** ...

Through some conversation, Marin learned that the sulfuric acid that Meggio escorted this time was the output of sulfuric acid produced by several alchemists in the city of Florence in three months. A total of 100 clay pots, each of which looks like a liter, These are dilute sulfuric acid with normal concentration. The reason why clay pots are used instead of oak barrels is because sulfuric acid corrodes oak barrels. However, dilute sulfuric acid is sufficient to dissolve the iron gate. If it is replaced with concentrated sulfuric acid, it will not dissolve the iron gate. Because concentrated sulfuric acid will form a protective film with iron. Marin even wondered—when dissolving the iron gate with dilute sulfuric acid, should he collect hydrogen to make a hydrogen balloon?

Then, Marin was too lazy to pay attention to Mezio, promised to promote him and reward 500 gold coins, and then sent him back to Florence.

After sending Meggio away, Marin happily returned to Siena with the army and the dilute sulphuric acid in a cart of 100 clay pots.

That night, while the enemy was not paying attention, Marin arranged for a trusted special forces member (this tactic is also secret) to hold a clay pot of dilute sulfuric acid, avoiding the enemy's sight over the city and quietly touching the tin In front of the big iron gate at the northwest gate of the city of Jena. Then, the soldier carefully picked up the clay pot and poured the dilute sulfuric acid in the pot to the big iron gate of the northwest gate of Siena ...

But to the surprise of this Special Forces soldier, the iron gate was not dissolved into a large hole as Marin said, but flowed down the iron gate, causing slight corrosion to the bottom of the iron gate. However, the effect is not very obvious. If this efficiency is used, even if the 100 cans of dilute sulfuric acid are used up, the big iron door will not be corroded ...

So, this member of the special forces immediately went back to report this unfortunate news to Marin ...

"What? The corrosion rate is slow? And it all flows to the bottom of the ground?" Marin was taken aback—is his plan going bankrupt?

"Yes, this acid simply cannot stay on the surface of the large iron gate that was erected. Once splashed, it will flow down the smooth gate surface. Even at the bottom of the acid pool, it seems that the corrosion rate is very slow."

"The corrosion rate is very slow?" Marin thought for a moment, then suddenly realized ...

"My brain, this memory!"

Malin suddenly remembered that in the previous life, the chemistry teacher once said that the laboratory produces hydrogen, usually using metal zinc. This is because zinc is much more active than iron. The reaction with iron and dilute sulfuric acid is feasible, but the speed is very slow. Therefore, in order to show the phenomenon of generating hydrogen, the reaction of zinc metal with high activity and dilute sulfuric acid or dilute hydrochloric acid is generally used to produce hydrogen, and the obvious process of rising bubbles can be seen. If iron is used, it seems to be much slower.

Moreover, the reaction of pouring dilute sulfuric acid on the big iron gate and putting iron in dilute sulfuric acid are completely different. Immerse iron in sulfuric acid with sufficient contact area, even if the speed is slower than zinc, the time is longer, and the effect is obvious. However, throwing dilute sulfuric acid on the iron gate is different. First of all, the Iron City Gate is erected. Dilute sulfuric acid splashes up, and it will not stay on the gate at all, but will flow down the gate to the ground. Before I could touch the reaction slowly, I landed. 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 had money, and the iron gates they obtained were thick enough. If you want to rely on these 100 cans of dilute sulfuric acid to corrode and destroy the iron city gate ~ www.novelhall.com ~ It seems that the feasibility is not high ...

Also, Marin remembered that it seems that even in the previous life, even if zinc metal was used to produce hydrogen, zinc was ground into zinc powder in order to increase the contact area as much as possible. If it is whole, it is much slower. Because, if you want to corrode the metal inside, you have to corrode the outside part first ...

Iron doesn't react with dilute sulfuric acid originally, plus it is a large iron gate in one piece, it can't be thrown into the dilute sulfuric acid tank ... So, it's hard to use the dilute sulfuric acid to corrode and damage the rear iron gate Achieved ... At least, this car is not enough dilute sulfuric acid ...

In addition, Marin also thought of a very serious problem-even if he can corrode a big hole in the heavy iron city gate, it can't blow the city gate into the gunpowder barrel ...

why? Because the iron gate is not the same as the wooden gate made of oak ...

Generally speaking, if it is a wooden gate, as long as a hole is made in the gate and a gunpowder barrel is inserted, the gate will be destroyed and the road into the city will be obtained.

However, it was the oak gate that was easily damaged and appeared on the road into the city. Nowadays, the current gates are extremely heavy iron gates. Even if the buried gunpowder barrel exploded, it might not be able to explode the heavy steel gate. If the city gate is not damaged, what is the point of corroding the iron city gate into a small hole that can be inserted into the gunpowder barrel?

Even if the hole corroded in the big iron gate happens to be the location of the city gate latch, it is useless, because, during the city's offensive and defensive warfare, the city's city gate hole is often blocked. As long as the city gate itself is not damaged, the city gate hole that has been blocked for a long time may not be completely blasted ... So, the idea that the heavy iron city gate can be destroyed by dilute sulfuric acid was too beautiful ... …
