Li Yanzhao tried to write with a whole block of ink, but he couldn't write anything. He wanted to try to draw a map of the southern part of Longxi, but the situation did not allow him to use a brush all day. The tip of the brush dries out, and he can't be allowed to sharpen his ink at any time on the road. Without a handy writing instrument, he would not be able to draw as he pleases anytime and anywhere. In this way, he fell into deep thought.

The only writing instrument of this era was a brush, not a hard pen of any kind. If you find a knife or something like that, it's not convenient to carve something like bamboo and wood. Papermaking has been improved from Cai Lun to now for more than 200 years, and with such a convenient writing instrument, bamboo and wood tablets have naturally been eliminated.

On the way, Li Yanzhao thought as he walked. Soon he thought of the pencil. He remembered that in his previous life, he knew that graphite was used to make pencils. Although he could not find the graphite at this time, it was not feasible to grind the ink and mix it with clay to shape it, and if necessary, to make it hard by firing it to facilitate writing.

After arriving at the camp in the evening, the villagers were busy cooking, and Li Yanzhao began his experiment. He took a little water and used the ink strips he bought yesterday to grind into ink in the inkstone. He was afraid that the color would not be enough, so he grinded it for a long time, until the ink of an inkstone was very black. Then he took a handful of soil and put it in the inkstone, trying to mix the soil and ink thoroughly.

He didn't care about getting his hands dirty, so he just reached out with his hands and stirred the mixture. However, the degree of stereotyping of the mixture has not been satisfactory. So he kept adding dirt, and finally made a big black lump of mud. After working for a long time, Li Yanzhao also knew that this thing could not reach the level of her own imagination and requirements, but now there is really no condition, so she has to use it immediately.

Li Yanzhao laid the mud on a stone to dry. Next to him, Liu Zhongkang, Liu Jiwen, Liu Jiwu brothers, as well as the second brother of the Cao family, and the second Zhuang who has been helping Li Yanzhao build a shack these days, also brought a group of young people from the village to talk about it.

"Li Gongzi has made such a big lump of black mud, what are you going to use it for?" Er Zhuang scratched his head with his hand and asked innocently.

"Drawing, writing, you can do it." Li Yanzhao smiled gently at him. For this simple young man, he has always felt very good in his heart. In his previous life, he also admired those who were honest and loyal.

"Well, that's a good idea." Liu Jiwen sighed while stroking his beard.

"Can this thing really write and draw like you say?" Cao Jian's face was full of disbelief.

"When it's dry, let's try it, I'm just for convenience, and to be honest, I'm not sure if it's good or not." Li Yanzhao said helplessly to Cao Jian.

No matter what, everyone still expressed great enthusiasm for Li Yanzhao's idea and were amazed.

"Little friend, how did you come up with this?" Liu Zhongkang asked in surprise while bowing his head frequently. He used to be a lili official, and whenever it was time to collect grain and pay taxes, he inevitably had to write and paint. Not to mention that there are often some correspondence and the like. And at this time, there is no guarantee that you will always be like being in the study, with a flat table and the four treasures of the study at hand. There are often many inconveniences, often just remembered things, or just thought about how to put down the official documents, so that they hurried back to the study, poured water, polished the ink, and spread out the paper. If it is really as Li Yanzhao said, if this thing has such a wonderful use, it can also save a lot of trouble.

"Yesterday evening, I walked on the road and watched the loess flying on the side of the road, so I had an idea and experimented with these things." Li Yanzhao said with a smile. In my heart, I was thinking, if I told Liu Lichang, in the world a thousand or hundreds of years, no matter women, children, the elderly, ordinary people, officials, everyone will use the pencil improved by this thing to write and draw. Can they believe it?

After finishing his work, Li Yanzhao found that his hands were as black as ink, and he helplessly stretched out and smiled bitterly at everyone, and then rushed to the water to wash his hands. Liu Jiwen, who reacted, hurriedly went to get the bath beans and gave them to Li Yanzhao to scrub.

After working for a long time, Li Yanzhao drank some gruel with everyone. The women set up a fire again and boiled the herbs against the plague. Li Yanzhao is still a little afraid. Fortunately, he and Liu Zhongkang found it and prevented it early. If it is a few days late, wait for those plagues to break out on a large scale among his own people. I'm afraid that these nearly 200 people can only die in a foreign land, and the violent corpses will be in the wilderness.

Liu Jiwu also told Liu Zhongkang about the diagnosis. Liu Zhongkang called Li Yanzhao to ask to no avail. Li Yanzhao kept silent about the price he paid, which also made Li Yanzhao and the few people who knew about it respect him more and more.

At nightfall, everyone drank the medicine and the shacks were built. Li Yanzhao has always been very careful about the precautions at night, and Liu Zhongkang also adopted his suggestion, and he also sent young people to take turns to be on duty at night. It is according to the system of Li Yanzhao's army in his previous life: two people in the army, when the time is over, one of the two people on duty at night will come back, and the two people on duty at night will be on duty when they wake up, and when they are over, one of the two people who will be on duty at night will come back, and two people will be on duty at night when they wake up...... And so on.

The ancients didn't have such a thing as clocks and watches. During the day, the city's residents can listen to the bells and drums, and the countryside can also estimate the time by looking at the sun and the sky. It's not exact, but it's pretty little. At night, however, there are still watchmen in the city to tell the time, and in the countryside it is not very feasible to estimate the time by what changes in nature make it possible. However, Liu Zhongkang told him about the astrological timekeeping method. A set of theories such as "falling due south, the stars are moving". Ren Li Yanzhao is a well-informed later generation, and he also has a headache when he hears it. Fortunately, I don't have to be on duty at night, so I don't need to understand the complicated theoretical system.

By this time, it was past the autumnal equinox, and it was getting dark early. Before long, everyone was already in the shack and falling asleep. Li Yanzhao thought of the future generations, at this time, most of the future generations were still brightly lit. Maybe you'll be staggering at the wine table at this time, or you'll be strategizing in the virtual space. In my previous life, I liked to play strategy games like governing the country and unifying the army on the computer. It's just that he was created to make people and threw him into this era of war.

Although he was in the army in his previous life and was familiar with military books, will this era of ups and downs give him a place for a traverser who comes from the next generation but knows almost nothing about this era?

Thinking about the happy or sad things in his previous life, Li Yanzhao fell asleep. His face was like water, and he didn't know whether he was happy or angry.

In the middle of the night, there was a sudden sound of horses' hooves at the end of the road. Li Yanzhao woke up in horror, but the sound of horses' hooves sounded thunder in his ears. He jerked up, lifted the blanket that covered him, and rushed out of his shack. The young men on duty at night obviously also heard the sound of horses' hooves, and hurriedly knocked on the bangzi in their hands, and the camp was full of golden drums for a while, and the chaos continued.

"Young people quickly protect women, children and the elderly After going to the mountain, don't panic, go quickly!" Li Yanzhao's angry voice sounded in the camp. The young and strong families seemed to have the backbone of the heart, and slowly retreated to the mountain next to the road to protect the old and weak women and children of their own families according to their words. After a while, Cao Jian carried a big bow he used for hunting and a pot of carved arrows and ran to Li Yanzhao's side. When Li Yanzhao saw him coming, he asked, "Where are the women and children in your family?" ”

"The foolish brother escorted them to the mountain." Cao Jian replied. Listening to the sound of horses' hooves getting closer and closer, his face did not change.

Li Yanzhao sighed, good man. At this time, even he had palpitations. He was afraid that he would come to this era, and before he could add his own strong strokes to this picture of the troubled times, he died in the wilderness. However, although he was slightly afraid in his heart, the will and temperament honed in the army supported him to be calm.

Subsequently, the two brothers Liu Jiwen and Liu Jiwu also ran over with a sword in their hands, saying that the family had settled down. After a while, even Liu Zhongkang came to Li Yanzhao's side with a group of young people, holding hoes, sickles and other farm tools in their hands.

Li Yanzhao was shocked: "Old Liu, go to the mountain for a while, this place is dangerous!" ”

However, Liu Zhongkang looked down on life and death: "Don't worry about Xiaoyou, the old man took his neighbors and left his hometown and traveled thousands of miles, just to beg for a way out." Today's difficulties are unavoidable. If a few of you are in trouble, will the old and weak women and children on the mountain ridge escape? If you combine the strength of everyone and fight him, there is still a glimmer of life. If you are trapped in the mountain beam, it is really the way to die. ”

Hearing the old man's generous words, everyone was deeply convinced. However, Li Yanzhao knew very well that if the group of knights on the opposite side were mountain bandits and horse thieves and came with malice, then there was no reason for these villagers on his side to survive.

In the previous life, the strategy game was played a lot, and the cavalry faced a group of light infantry with no heavy armor, no spears and long knives, and no strong bows and crossbows, and the result was really tantamount to slaughter, not to mention that this group of people on his side were a group of villagers who had not been trained in the military, and they were not even light infantry.

Listening to the horses' hooves getting closer and closer, everyone nervously held the weapons and farm tools in their hands. Cao Jian had already taken out an arrow and put it on the string, ready to go.

The sound of horses' hooves was getting closer and closer, Cao Jian listened attentively, and then raised his head and said: "About fifty horses, from east to west, there are still miles left." ”

Li Yanzhao couldn't help but glance at Cao Jian. He had learned from books that there were some people who could hear and distinguish their positions, and even know what was coming from the other side, whether it was a beast, a knight, or a wild horse, and how many were coming. He used to think that this was nothing more than some ancient people's apocryphal bragging, until he saw it with his own eyes, and he knew that he had underestimated the heroes of the world.

The group of knights gradually appeared at the end of the road, and by the moonlight, everyone could clearly see the flag embroidered with the word "Chen" in the middle of the knights. More than fifty knights, all dressed in iron armor, with swords, guns, swords and halberds in their hands, flashed a terrifying cold light in the moonlight, and Li Yanzhao seemed to be able to see a trace of blood from above.
