Have you fought hard? Li Muyun wanted to ask why, but seeing Yu Zhining's old face flushed and his whole body trembling, he didn't give up this idea.

Let’s leave some way for this old man to live. It’s not easy to do anything for the emperor, so don’t make things difficult for him.

Thinking of this, Li Muyun lowered his head and looked at the book in his hand.

Hey, it's not bad. The old man didn't give him any big deal, just a thin thousand-character text. It seems that Yu Zhining is pretty good-hearted, although he is stubborn like a donkey.

"Teacher Yu, don't worry, I promise to complete the task. You'll see it tomorrow morning!" Li Muyun, who had slightly changed his impression of Zhining, shook the hand in his hand, turned around and returned to the table and started to flip it up, regardless of Lao Yu, standing at the door.

As a killer, if you ask Li Muyun what he is best at, his answer must be memory. Keeping his eyes open is one of the most basic abilities of the killer, so he really doesn't care much about memorizing the meaning. Anyway, he doesn't want to understand the meaning of it. Just memorize it. A thousand-character text and a thousand-character text are even more worth mentioning to him.

So Li Muyun, under Lao Yu's gaze, first flipped through it, then looked carefully, casually folded the book, and looked back at Yu Zhining who had not left yet: "Teacher Yu is looking at me? There is no need for this?"

"It's very necessary!" Yu Zhining nodded heavily.

"Okay!" Li Muyun smacked her lips, sighed and said dejectedly: "Then I'll finish reading."

"You have to recite it." Yu Zhining pointed to the book that Li Muyun held in his hand and said.

"I have already recited it, and I have memorized it like a stream!"

"Remember it and listen." Yu Zhining was already a little regretful at this time. He felt that Li Muyun must have recited a thousand-character text before, and this time it seemed that he would be confused.

"Okay, I really admire you!" What could Li Muyun say? Even if he is not a human, he can't beat the old man. Yu Zhining, who saw you not leaving without carrying me, said helplessly: "The heaven and earth are mysterious and yellow, the universe is vast and vast..."

A moment later, Old Man Yu was finally fooled away. Looking at the direction where the old man disappeared, Li Muyun breathed a long sigh. Thinking of the time when the old man left, it means that the interpretation will be tested tomorrow.

Forget it, I don’t care, let’s go to bed first. Let’s talk about tomorrow’s things tomorrow. It’s almost over a little while before the sky falls. I guess I won’t have to sleep this night.

...

The next morning, Lao Yu got up early, and just dawned, he ran to Li Muyun's door to block him.

You know, this is the dog days of summer. According to modern times, it is basically dawn around 4 o'clock in the morning. This shows how stubborn Yu Zhining's temper is.

But, but, Lao Yu is still late.

Looking at the empty room, Yu Zhining also had to admire Li Muyun's ability to skip classes.

At the foot of the mountain, Li Muyun laughed to the sky: "Hahaha, old guy, I still want to block me, hey, I don't even look at what I do, I missed back then..."

"What did you think of back then?" The fat man who came back from inquiring about the "enemy situation" asked curiously.

"Think about it, let's go, today the cement can be formed." Li Muyun rolled his eyes.

"Tsk, don't say it if you don't say it. I don't know what secrets do you have." The fat man also rolled his eyes to Li Muyun.

But he didn't know that the "then" mentioned by Li Muyun refers to his previous life. Thinking of skipping class when he fought wits and courage with his teacher at that time, it seems to be a beautiful memory now.

However, it was precisely because of his skipping classes that he took the path of killer, but this is already another story. If you are interested, you can refer to "Danger's World".

...

Leaving the mountain village, continuing to walk deep into the mountains for two hours, stepping on a small path full of ruts, and walking for another quarter of an hour, you can see a row of stone caves driving on the mountain wall. Of course, more professionals may also call these caves caves caves.

It was almost noon at this time, and the scorching sun was hanging high in the sky. Combined with the rolling smoke from the caves, the entire valley was as soul-stirring as the saunas in later generations.

The fat man couldn't stand it as soon as he walked into the valley. He took off his shirt and shook his fat body with his bare shirt and shouted: "Li Muyun, next time I come here, can you not bring me with me? I know that I'm afraid of heat and I still ask me to come here. Do you want my life?"

Li Muyun ignored him. This was not the first day he heard it, and it would not be the last time he heard it. There was no need to argue with the fat man.

"You are here, Mr. Hou? Come and see the cement again?" Feng Junyi, the person in charge of the fired coke, saw Li Muyun and the others, immediately came up to greet him.

"Yes, how is the cement firing work? Is there any progress?" Li Muyun nodded and asked.

Feng Junyi turned his head and looked at the smoke-filled caves, and said with a wry smile: "Not yet, but a lot of lime is burned."

"Save them all, those limes will be of great use in a while." Li Muyun also knew that it was impossible to test such things, so he said lightly while walking.

Many things in history have happened unintentionally, such as the invention of Coca-Cola.

Moreover, it is also very important to experiment with this thing. Many times, even if you know the formula for something or even have all the raw materials, you may not be able to come up with what you need in actual applications.

The simplest example is cooking. You can find many recipes online, but when you really follow the recipe, what you cook does not necessarily taste like you imagine. Unless you have been tested countless times and someone needs to teach you step by step, you may have the possibility of success.

The same is true for Li Muyun to burn cement.

He knew what the ingredients of cement were and how to fire it, but these were all theory, but when it really started to burn it, the problem arose.

Because he cannot control the furnace temperature and naturally cannot accurately control the materials without knowing the furnace temperature, the things burned out either are either undue or overfire, which is also the biggest difficulty facing the burning of cement.

Just as Li Muyun was in a state of confusion over the cement, a fast horse was racing towards his mountain village like flying.

The knight's head was covered with sweat and his face was full of anxiety, as if something big had happened.
