After throwing Kong Rong to Cai Yong and Zheng Xuan, Zhao Feng finally breathed a sigh of relief. At first, Kong Rong still looked unwilling, but after the two old men whispered something in his ear, Kong Rong miraculously agreed!

Even Ma Riyan was arranged by Zhao Feng to go to Liaodong College, and with the publicity of "Liaodong Daily", Liaodong College has come to life again. In this way, Zhao Feng is happy to be idle, no, he is sitting in the courtyard, enjoying the warm afternoon sun.

"Master, Shi Dali from the craftsman's workshop came to ask to see the lord!" Just when Zhao Feng was humming a little song and wanted to take a break, the townsman suddenly found Zhao Feng.

"Huh?" Zhao Feng was slightly stunned, what would happen when Shi Dali came to him? You don't think you've been looking for him lately, have you?

However, doubts are doubts, Zhao Feng still got up and came to the front hall. I saw Shi Dali leading a young man to sit there, his face seemed to have a look of joy, and the young man's face was full of anxiety.

Seeing Zhao Feng coming, Shi Dali hurriedly got up to greet him: "Lord, this is Lu Shen from our craftsman's workshop, a student who graduated from Liaodong College!" He recently discovered an interesting phenomenon, I don't understand what is going on, but what he said seems to make sense, the lord said, if you have any new ideas, come to you, don't I bring him! ”

"Oh?" Zhao Feng is quite interested in this, the wisdom of human beings is infinite, whether it is the ancients or modern people, as long as their minds are liberated, there will always be someone who will give you a different surprise!

"That's right, Chenxi (Lu Shen's words), you and the lord yourself!" Shi Dali patted Lu Shen's shoulder.

"Lord...... Lord! Lu Shen swallowed. That's right, he was very nervous, very nervous, he was only twenty years old, he had only heard others say how Zhao Feng was before, he had never seen Zhao Feng with his own eyes, and now that he saw a real person, it would be strange if he wasn't nervous.

"Don't be nervous, just treat me as your friend, just do whatever you want, don't be too restrained!" Zhao Feng smiled slightly.

"Yes!" Lu Shen took a deep breath, with a faint joy on his face, "Lord, please come with Shen, it's too troublesome to tell here!" Going to the artisan workshop is a little more intuitive! ”

"So mysterious?" Zhao Feng smiled, "Lead the way!" ”

"Hmm!" Seeing that Zhao Feng agreed, Lu Shen was extremely excited and led Zhao Feng towards the craftsman's workshop.

When he came to the craftsman's workshop, Lu Shen took a boiling kettle and sat the kettle directly on the stove.

Seeing Lu Shen's actions, Zhao Feng was pleasantly surprised, could it be ......?

"Lord, wait a minute, the phenomenon will not appear until the water is boiled!" Lu Shen said.

"Hmm!" Zhao Feng is very excited now, if it is really what he thinks in his heart, it is an epoch-making discovery, which will greatly change the status quo of Liaodong's industry!

Before, Zhao Feng did not take the initiative to guide the craftsmen to think about this, because he believed that the industry in Liaodong still needed to develop, and he was not in a hurry to enter the steam age! It's just a matter of letting things be.

What I never expected was that this was discovered at this moment, if this Lu Shen discovered that it was really the effect of steam, Zhao Feng could use this to open a new era!

Slowly the water boiled, just like boiling water at normal times, and the lid of the kettle jumped and jumped on the top of the steam.

"Lord, look, is this kettle lid pushed up by an inexplicable force? And, if Shin is not mistaken, it is the kind of gas that is produced when the water is boiled! It must be this gas that pushes the kettle lid! If we can use this power and replace manpower with this power, we will free up too much, too much labor! The more Lu Shen spoke, the more excited he became, and after he finished speaking, he looked at Zhao Feng with anticipation.

"Good! Good! Good! Zhao Feng was also excited, you must know that Watt discovered this phenomenon more than 1,500 years later! More than 1,500 years ahead of the West! What kind of lead is this? With this lead, Zhao Feng is completely confident, if he is against the Roman Empire in the future, he can completely defeat the Roman Iron Cavalry!

"Well, I'll tell you about it first!" Zhao Feng held back his excitement and began to lecture for Lu Shen, "Actually, water, ice, and the gas you see now are all one substance, but three forms of a substance!" ”

"A substance? Three forms? This is the first time Lu Shen has heard of this new theory.

"Yes, water is liquid, so it's liquid, ice is solid, we call it solid, and this water vapor is gas, so we call it gaseous. Here we would like to introduce a few new words – melting point and freezing point, boiling point and cooling point! ”

"Melting point? Freezing point? Boiling point? Cooling point? Lu Shen was completely confused, and he didn't know the meaning of these four new terms at all.

"Chenxi, have you paid attention to this phenomenon in your life: when the temperature is cold to a certain extent, the water on the road or in the river will freeze, and after the temperature rises to a certain extent, the ice will melt into water again!" Zhao Feng asked.

"That's right, my lord, you're right!" Lu Shen nodded.

"But if you put the oil at the same temperature, it won't freeze! Did you find out about this? Zhao Feng asked again.

"Uh......" Lu Shen thought hard for a moment, it seemed to be like this! Yes, that's right! ”

"That's right, because the melting point of different substances is different, the freezing point of water, or the melting point of ice, is zero, so once the temperature is below zero, the water will slowly freeze! Conversely, once the temperature is above freezing, the ice melts into water! Zhao Feng explained.

"Degree zero?" Lu Shen was puzzled again, what kind of temperature is this zero degree?

"Uhh......h

That's why the temperature at which the water freezes is called zero! And when you just boiled water, the water gradually boiled, and the temperature of the boiling water was set to 100 degrees! Zhao Feng shamelessly introduced the concept of Celsius in advance.

"Oh! I see! Lu Shen nodded as if he didn't understand.

"Plus, I'm going to introduce you with a new word – volume!" Zhao Fengdao. Now he doesn't have any of these words, and he himself thinks it's really troublesome to tell!

"Volume?" Fortunately, Lu Shen's brain is enough, and these words are quite acceptable.

"Yes, it means the space that a substance needs to occupy!" Zhao Feng nodded, and had no choice but to tell it in layman's terms!
