To Four Thousand Years Later

"That is to say, while the first furnace is generating hot air, the second furnace is preheating the Leonardo Thinkro with the exported exhaust gas.

"That's right, sir!" Old Frederick replied immediately, "After the hot air entering the open hearth furnace is heated by the exhaust gas, it can directly exceed six hundred degrees." In this way, energy can be greatly saved and the efficiency of steelmaking can be improved. At the same time, It can ensure the continuous supply of hot air to the open hearth furnace, accumulate the furnace temperature, and greatly prevent the loss of heat energy.

"You are a genius, Frederick." Leonardo sighed sincerely, "No wonder it can melt scrap steel." By accumulating heat in this way, the indoor temperature can indeed rise to the threshold without consuming too much fuel.

After the discussion, old Fendrek finally calmed down.

He realized that he had been discussing the iron stove with this great man for so long. Suddenly I felt a little panicked. He also didn't know if Leonardo had such a high opinion of him, whether it was some inaudible irony or not; he also didn't know if he had committed any taboo just now.

Old Frederick suddenly felt a little regretful in his heart.

I am making an old mistake again!

As soon as his professional field was mentioned, old Frederick would get excited involuntarily, and would start talking about some things. Not only is he talking to himself, but he even likes to interrupt others, and he can't help but mix in some dialect slang and swear words that are prevalent among inferior people. Old Frederick had offended others because of his fault before, and he had learned a lot.

But he still doesn't have a long memory

Roughly speaking, it is "I was wrong, I'm sorry, I dare to do it next time". At times like this, he would always get carried away subconsciously, and regardless of who was facing him, he looked at Leonardo cautiously and courageously. But unexpectedly, Leonardo didn't respond.

He just lowered his head and brushed his head down to write something.

Old Frederick watched him anxiously, waiting for him to look up again.

"Don't be so nervous, Frederick."

He spoke in a gentle voice, with a heart-warming power in his voice: "Sit down. I'm really sorry for making you stand and talk for so long.

"I don't have so many rules here. We are just friends exchanging experience and knowledge. I am not a nobleman, so you don't have to be so respectful to me. The old craftsman hesitated for a moment, then agreed.

He found a seat that didn't look that high-end, and sat down carefully, with his weight still leaning forward on his lap.

Leonardo just smiled: "I remember, the rigorous Siemens I've heard of shouldn't look like you now.

"People are old, old. People shook their heads again and again, and the man with a wry smile said: "It's not so much anger, but not as anxious as when I was young. It's a good thing, it's a good thing. "

"Not necessarily.

Leonardo sighed: "I know that Mr. Siemens is famous for his outspoken temper. His apprentices are afraid of him, but they respect him.

"How can there be such

Yes, Frederick.

Leonardo replied calmly: "Your Excellency Siemens is such a person. I have always believed in him like this.

The old craftsman was stunned for a moment, and then his eyes became moist.

He couldn't help but reached out and **** himself deeply. In the wrinkled eye sockets, the gray eyeballs were stained with water, but they seemed to become much brighter.

"What you said is, my lord, old Fendrek was silent for a long time before changing his words, and said in a low voice: "He is such a person, he has always been. Leonardo smiled slightly when he heard the words.

His gaze has not changed, it is still so gentle and peaceful. He stared at him, but the old craftsman couldn't help the tears in his eyes again.

"I'm sorry, my lord."

He said, "Sorry, I thought

"I said, you are a genius, a real genius."

Leonardo breathed a sigh of relief and said in a low voice: "And they didn't even discover your true talent, and didn't discover the true value of the open-hearth steelmaking method.

As he spoke, he handed the manuscript in his hand to Frederick. Frederick stood up, subconsciously bent over, and took the notebook handed over by Leonardo with respectful hands.

He lowered his head to look slightly, and the whole person was stunned. Leonardo replied calmly: "You used coke as the main raw material before, and the cost was too high. If you have it, you can greatly reduce the cost. And you can avoid the heaviest problem. Frederick His eyes lit up, and he became excited involuntarily. His back straightened, and under the excitement, his voice became loud and clear: "I was thinking about this before! This is what I worry about!

"Even if the flame is reversed through the switch, the temperature of the kiln still can't be finely controlled. I can't raise it or lower it if I want to. Oh, this is what worries me the most! When he said this, his face turned pale. Sudden stagnation, he realized that his voice seemed too loud. But before he apologized again, Leonardo made a voice of approval: "You will think of it sooner or later, Frederick. "

Leonardo said calmly: "Because that's what I see in your invention. With the gas furnace, the open hearth is a complete invention.

"Yes, yes! What you said is true! But. Old Frederick nodded repeatedly, showing hesitation: "Are you planning to sell this patent to me? "I have no such plans.

"That's it!" Old Frederick was a little disappointed, but still nodded: "That's right, this is something that you worked so hard to invent, sir. It happened to make up for the lack of my invention. "Where is it, isn't this something you invented?"

Leonardo just spoke lightly. Leonardo put his hands on the table, and said in a calm tone: "I don't want any patents. I don't like this patent either. What I like is you. Your Excellency Siemens.

"It's your mind, your precious intellect and knowledge that I'm after.

"As you said before, if you give you a few more years, you can also invent the gas furnace. I will save you the next few years, and you will come to work for me for a few years. The master craftsman will pay you three times the department salary. Hearing this, Old Frederick is obviously a little moved.

But he hesitated again and again, and shook his head slowly and firmly.

Old Frederick looked at Leonardo with a wry smile: "May the patriarch Solomon open his eyes. If he opens his eyes, the old man can guarantee my five-year life and I will be able to invent the gas furnace, but I know my body. I The old thing's gone, sir. Worn out in youth, and now it's just more money for the children.

He read brokenly: "My son has gone crazy for some reason. He bought a horse, and the family has no savings. But my granddaughter is eight or nine years old, and she should get married in a few years, so I have to back up the dowry." ; My grandson is just three years old this year, and his parents are not very good, I have to prepare a deposit so that he can read in the future "Then I will give you three thousand pounds, and you will work for me for ten years first, okay? "

Leonardo interrupted.

Old Frederick was a little moved, but he just shook his head stubbornly: "Don't say it's been ten or five years, old man. I won't be able to live in three years. You are a good man, sir. I can't cheat your money." As long as you want , I naturally have the ability to help you survive.

Leonardo said lightly: "Five thousand pounds, how about it? From now on, you will work for me, and I will let you live.

Not to mention buying my useless life for five thousand pounds, this afterlife, and the afterlife of the afterlife, is also sold to you.

Old Frederick was shocked by this confidence, and it took him a long time to come back to his senses, and whispered: "It stands to reason, you are a good person, you are so polite to me with such a high status, I shouldn't accept you. But I've been really saying recently, "You can accept it with peace of mind. Leonardo replied: "When you leave in a while, I will give you the money. You pack up, settle down, and come with me in three days.

"Where are you going?

Old Frederick asked subconsciously. Leonardo replied.

Hearing this, Old Frederick was startled for a moment, then as if he understood something, he gritted his teeth and agreed: "Then I will sell it to you from now on, as long as I can move, I will do whatever you say, sir." What to do. Leonardo calmly replied: "You are sixty-eight years old, but you still don't know where your talents are, so let me show you.

"Go home, Siemens. We will be in Florence when you see these familiar things again.

Leonardo had no intention of breaking the rules. Now that the patent has been sold, unless he buys it back normally or invents it himself, he will not use coercion or deception to force others to hand over his patented technology. Because he has a better choice.

Since you can't buy technology, it's better to just pack people up and take them away. Anyway, you also think that this craftsman has no value anymore, why don't you give it to me? Leonardo could see clearly—why old Frederick was so weak? Because his unawakened spiritual energy has been absorbing the vitality of his body to strengthen itself, but because his body is too fragile, he has never been able to truly awaken. This forms a vicious circle.

A rare enlightened person. The real ones are not dead.

It's a pity that he is too old to awaken, and has lost the hope of awakening psionic energy if he hadn't met Leonardo.

Leonardo stared at the leaving back of the old craftsman, and said: "Pack up your things, Lie Lakin. We are also preparing to leave.

"Don't wait for the Duke to come back.

The Demon God, who was wearing a dark green suit, asked casually.

"Yes, no more. He should be safe now," Leonardo said pointedly, "but if we stay here and don't leave, he may not be safe."

He looks into the void beyond, so says the speaker.

There seemed to be a pair of golden vertical pupils, watching him from a distance.
