The reason why he did this was not to say what the painting was like, but the few words written on the painting made him stunned: "The temperature is extremely high!"

The temperature is extremely high, how high is it? Hu Guang couldn't help but ask in his heart. He looked up at the mason and peeked at him with a little nervousness, so he had to relax the expression on his face and start looking at the stove painting again.

At this time, someone began to hand over the papers one after another. The eunuch kept walking back and forth, presenting all the mason's paintings to the imperial court.

Hu Guang turned it a little bit and found that it was almost the same. The comments about temperature, either that the temperature is extremely high, the temperature is the highest, or that the temperature is rare, are all adjectives!

What made him a little depressed was that these masons did not mark each part like the illustrations in later generations. If the stove was not very complicated, Hu Guang would have probably lost even if he woke up his spirit.

But in this way, if Hu Guang wants to figure out the design pattern and intention of each of the test papers and then evaluate how high the temperature may be, it will consume a lot of his time and energy.

I don’t know if I should be happy or depressed, but most of the design drawings of the stove are similar, which saves Hu Guang a lot of time.

But even so, Hu Guang was busy until it was almost evening before he finally passed all the design drawings, and then he only left eight more distinctive design drawings. The rest of the people gave them some rewards to go home.

Looking at the eight people who stayed, six of them were dressed in good shape. They probably had poor family conditions and the other one was in a bad state. The patches of the clothes were simply beaten and then.

In the late Ming Dynasty, the status of craftsmen also changed. Craftsmen with good craftsmanship had almost no bad conditions, and even had good aspects, such as those related to writing, and they were often guests of scholars and officials.

Hu Guang looked at the eight people below and saw that they were a little uneasy when they were excited, so he said with a smile: "I think the test papers you handed in have their own characteristics, or they are not different from each other. It is not easy to judge how high the actual temperature in the furnace can reach. Therefore, I ask you to answer another question, which is optional. In other words, you can choose to answer or not, and I will not blame it. It is only used to distinguish which level of the eight of you is higher and which is lower!"

When these eight people heard this, they thought that this was the purpose of the emperor calling him to come?

Hu Guang did not let them think for long, so he directly asked: "You write down your experience as a bricklayer, write down what you are best at, that is, what you know how to write. If you don't know how to write, someone can do it for you."

Speaking of this, he emphasized: "I have said that this question is related to your meal questions. You can choose to answer or not. I will not force you, but I just can't get my imperial pen and give it to you."

The eight bricklayers were a little hesitant after hearing this, and no one wrote their experiences as soon as possible. After all, this is indeed related to their unique skills. What should they do if they spread it and what will their descendants do?

If you write a little random words, go out and inquire, you will know if you have written out what you are good at, and deceive the emperor by lies? This is a serious crime!

Compared with unique skills, the plaque "Master Mason" given by the emperor seems less important. After all, you have to be able to eat and think about the matter of glorifying your ancestors.

Thinking of this, a well-dressed mason looked at the emperor above and said a little uneasy: "Your Majesty, this meager skill of the grass people has been passed down from generation to generation. Without the consent of the ancestors, it is really impossible to pass it on. Please forgive me!"

"Haha, I have said that this question is voluntary. Since you don't want to decide the winner, I won't force it." Hu Guang said with a smile, then waved his hand and said, "Look at the reward."

This is the same as ordinary people serving tea and seeing off guests. When the mason heard this, he quietly wiped his sweat and left again and thanked him again.

With him taking the lead, five well-dressed masons gave up on answering questions, and in the end, only three masons were left in the side hall.

Hu Guang looked at them and asked with a smile: "Did you leave a question to answer?"

The three of them looked at each other and finally responded in unison: "Your Majesty, we are willing!"

After hearing this, Hu Guang waved his hand and signaled them to answer the question. The man in the dress was writing by himself, and both of them needed to do it for others, and they whispered to themselves.

This time, Hu Guang did not wait long, and the three of them handed over the papers one after another. However, he did not look at the test papers, but just looked at the three of them and said, "What I said before was actually an excuse. The real purpose was to choose the best to make a new thing for me. I roughly know how to do it, but you need to grasp the details. If this thing can be burned out, it will be a great benefit to my Ming Dynasty, which is a major event that concerns the national economy and people's livelihood. And you, I will also reward you with official positions, and in addition to receiving salary, you can also receive some dividends. How about it?"

The three of them were surprised and happy when they heard this. Unexpectedly, the emperor actually involved in the work of the bricklayer and came up with a new thing. It was so amazing! They could hear that the emperor was just asking for help, and he could also get the reward of official positions and money. It was so great!

"Ding, achievement value +1, comes from mason Tang Binghong!"

“…”

The achievement is worth +3, but Hu Guang didn't care. Seeing that they were all happy, he reminded them: "This matter must be kept confidential and cannot be told to anyone!"

This is what it means, and all three craftsmen know.

Seeing this, Hu Guang officially told him: "What I want to burn is a binder similar to Sanhe soil, which can bond mud and gravel, which I call it cement. This kind of thing is probably made of clay and limestone. In terms of ratio, it should be more clay, or some other materials can be added. This requires you to burn more experiments..."

As long as later generations have read historical time travel novels, cement is probably the most common black technology. Hu Guang probably remembers it, but he doesn't remember it very clearly. He only knows that the temperature in the furnace must be high enough to calcin out. Therefore, in the first question, he came up with such a question to collect the ideas of famous craftsmen in the capital, but he would not let people outside guess what they were doing.

Before, Hu Guang's thoughts fell into a dead end. He kept thinking about how to drink a bucket of water in the Ming Dynasty at that time. He never thought about how to add water to the bucket so that there was enough water inside so that everyone had the idea of ​​drinking.

Cement is the easiest black technology to be found. Although it will take a long time to make profits, Hu Guang has already made plans and several means to use them together should be able to solve the current serious shortage of money.

As a result, Hu Guang did not care about anything else in the next few days, and worked with three bricklayers to study and fire cement.

The news spread outside, causing all the civil and military officials who had experienced the Apocalypse to react immediately. Could it be that they had revealed their nature today - a good bricklayer's life?
