Yang Shan's eyes widened suddenly when he heard the "requisition order" issued by the young official in front of him. Pen, fun, and www.biquge.info

Build the Great Wall to stop the Southern Barbarians?

What a joke!

He is not one of those people around him who does not know the history books and does not know the big characters, although he has been studying with his mother since he was a child, although he is far from being able to talk about the ancient and modern, but at least he still understands the basic truth.

These Great Walls that have been built in the world, which one did not take several years to build to the current appearance, you must know that the Qin State before the Han Dynasty took more than seven years, to say the least, and it was done with the power of the whole country. How many years do you want to build a wall about the same length in the south as it is in the north? With the population of Yizhou, don't even think about it for more than ten or twenty years!

I'm just afraid that when the time comes, I won't even lay the pile, and I will be served by the barbarians from the south!

Thinking of this, Yang Shan suddenly found that his original good feelings for the local officials had disappeared without a trace in an instant, looking at the previous dynasties, there were too many such guys who made orders in a hot head, and in the end, the facts would prove how wrong they were.

However, seeing the unreformed "younger brothers" behind him who were already obviously emaciated, Yang Shan had to sigh.

Maybe this is just a government relief or a response to disperse the displaced people?

"I hope so." He shook his head and didn't squeeze into the crowd to sign up. Although there is some guarantee along the way with the government's requisition, the speed is definitely not fast, and when they go, where have they won those men, most of them will encounter the situation encountered in the place where the embankment was built before.

Yang Shan, who was on the same floor, turned around and walked to the companion who was suspicious of his brain under the shade of the tree, pressed all the thoughts in his heart to the bottom of his heart, and even forced the corners of his mouth to rise.

"Let's go, let's go back to the south."

……

"How's it going?"

Seeing Ma Jun, who looked tired but excited, Liu Chan shook the pen in his hand and asked.

This time, no ink splattered.

Ma Jun glanced at the pen in Liu Chan's hand in surprise and said: "Young master, everything has been prepared, almost eighty percent of the displaced people have participated in the recruitment, under the deployment of the county government, they will march to the south on the same day, and General Zhao Yun has also replied, but the specific content is not known." ”

"Such military orders should only be read by the Taishou level, and it is reasonable that no one will know you." Liu Chan nodded, the construction of the Great Wall is the one thing he is most concerned about in recent times, one is because this matter is the first large-scale use of cement, and the other is because it is also related to a big plan in his heart, but this can only be implemented after the south is completely pacified, but now there is no need to rush.

As for Liu Chan's contemplation, Ma Jun stared at the pen in his hand for a long time, and finally couldn't help but ask with curiosity: "Young master, this thing ...... Why? ”

Liu Chan was stunned for a while, and it took him a long time to realize that he was asking about the pen he was holding in his hand.

He smiled softly, this pen was a fetish that he had just remembered recently.

"This thing is called a pencil." He pulled out one from a wooden pen holder and handed it to Ma Jun, who took it with both hands, picked it up and spun it around.

Liu Chan then picked up the graphite inkstone placed on the side and said, "Deheng can you know what material this inkstone is?" ”

The latter was stunned and replied, "Gai is...... Graphite? But this is ......."

Liu Chan nodded and explained: "When we grind ink, it is nothing more than pouring water, dissolving the graphite through grinding, making it into a fine powder and blending with water to form ink, and then using a brush to dip it into writing. But on the other hand, if this is the case, why can't we just use this graphite for writing? ”

Liu Chan's explanation looks ordinary in the eyes of modern people, but it is still a little obscure for Ma Jun, who has just come into contact with natural science, and it took him a long time to understand, and after thinking for a while, he asked in doubt: "But young master, graphite is brittle according to the basic natural science, and if it is ground to such a thickness, it will break with a little stress." ”

After speaking, he picked up the pen and made a stroke on a piece of paper on the table, only to find that under the unique feel and the graininess of rubbing against the paper, the graphite nib that he thought was brittle was not broken, but extremely strong.

"...... this?"

Seeing Ma Jun with a surprised face, Liu Chan picked up the pen and said with a smile: "I still taught you these properties, how can I not know them." This core is made by grinding graphite into powder and then mixing sulfur, antimony, rosin and other substances, which is hard and does not affect the original properties of graphite. The final object is ground into a thin column embedded in the wooden shell, and it becomes a pencil. ”

But as soon as he finished speaking, he seemed to think of something, and his originally smiling face changed suddenly, but Ma Jun in front of him was startled, and he almost ran out to call.

"No need." Liu Chan, who came back to his senses, stopped him, and the latter only saw that his face was as usual at this time, but he was only slightly depressed.

"Young master, I don't know what disturbs you like this?" Ma Jun hesitated for a moment, but still asked.

Liu Chan waved his hand, and the depression on his face slowly evolved into excitement.

He only knew how to use things like lead and antimony to make pencil leads, but he forgot that it was really a small loss!

"I'm blind." He laughed at himself, then looked up and said, "I still need to figure this matter out again...... Deheng, you go and call Yu Dan to come to the house, and I will explain it to you and the two of you at that time. ”

As soon as these words came out, despite the doubts in his heart, Ma Jun respectfully accepted the order and retreated, but when he left, he took a pencil with him, ready to take it back to study and study what hidden tricks there were.

But he was destined not to see anything, because even Liu Chan remembered it because of a flash of inspiration.

"Lead-antimony...... It's a great and essential material for making something like that......"

……

South.

Jiangyang City.

"General Xiahou, why do we really want to take the initiative to send troops to build the Great Wall?"

"Yes, building such a long city wall in one month is simply a fool's dream, you must know that Qin ...... at the beginning"

"That's it! It's all quiet! The general has his own thoughts about the general, and I am waiting for the noise, but it will only add to the general's blockage! Xia Houlan scolded, the majesty in charge of military law and extraordinary martial arts made him speak with great weight under Zhao Yun's tent, and as soon as he made a sound, the deputy generals who were originally noisy around him were suddenly silenced.

However, Xia Houlan, who said this, actually had some doubts in her heart.

In his opinion, the secret order from Chengdu was simply ridiculous, and they were asked to take the initiative to attack with less than 5,000 soldiers and horses, just to lay the necessary land for the sudden strategy of building the Great Wall?!

You must know that fighting a war is not a child's play, once the war starts, it will affect the whole body, even if you want to advance a mile, the manpower and material resources you have to pay are immeasurable, and their soldiers and horses at this time are simply not worth mentioning compared to the barbarians who have gathered all the forces in the south!

What surprised him the most was that after General Zilong received the military order, he really planned to complete it meticulously! But with his wisdom and strategy, it is impossible not to think of the problems that even these people can think of!

For this reason, although he was serious on his face, he was also resentful in his heart like the other lieutenants around him.

"I heard that this plan was made by the young master of Zen, this is simply nonsense! Now it seems that Liu Feng, the righteous son of the lord, doesn't know how many times stronger than him! ”
