Spoiling History: Starting from the Three Kingdoms

First she lost her husband, then her father.

She was killed by the Hu cavalry at the age of 21, and was held captive for 12 years before returning to the Han Dynasty.

Seven years after returning to the Han Dynasty, the Han Dynasty still lost power, and the heavens still did not return.

The prosperous scene of Xiping was only seen in my dreams when I was young, and I woke up in Yecheng with tears wet on my pillow.

She walked barefoot with disheveled hair and kowtowed to the prime minister, showing her gratitude to Dong Si.

She recited and remembered her deceased father, and presented 400 poems to Cao, showing her gratitude to Cao Xiang.

She was alone, with only poetry and the zither as her companions. She was already waiting to die before she was 50 years old.

What Cai Yan did not expect was that she came to stay with her sister in Shangdang temporarily with the idea that she would die by her relatives even if she died, but she saw another world that she had never seen in the book brought by Xin Xianying.

It is not to be sad about the passing of time, not to be arbitrary, and not to judge the world based on feelings.

Discuss your views based on things, analyze the traces based on what you see, and follow the principles based on the traces you see.

The simple soil under my feet has several different types, and the golden crow light I see when I look up has infinite changes.

Especially the conjecture about the heaven and earth:

The higher the mountain, the farther you can see, but the higher you climb, the farther you can see.

This is proved by mathematics, and the height of the mountain is the distance you can see, and the earth is calculated as an arc.

Although I don’t know what means the author used to see the distance, and although the process of mathematical judgment is extremely difficult to read, this method of argumentation makes Cai Yan feel more convincing than those theories based on ancient records and inferences from the heart.

However, Cai Yan has already had a vague guess about the means used by the person.

Although it is said in the chapter on light that transparent glass can gather and scatter light, Cai Yan recalled that when she was captured and taken to the land of the Hu, she had to work on ice in winter.

Therefore, she also knew that sunlight would converge and disperse when penetrating ice, and that the human eye would also see things in various ways. This kind of sight from a high place might be made of transparent colored glass.

The only pity was that she didn't know how to make transparent colored glass... It was not difficult to find colored glass in Yecheng, and she had colored glass beads to play with when she was young.

But those colored glasses were all of the best quality if they looked like jade, and the lighter and more transparent the color, the more expensive it was, not to mention completely transparent.

Now that Xin Xianying had finished reading all the "new books" in her hands, Cai Yan suddenly felt a little restless:

I wonder which strange man under the command of the left general Liu Bei is the author of this book?

That was why, when her sister Cai Zhenji came back and told them that the enemy army had marched to Shangdang County, Cai Yan didn't feel too panicked.

Xin Xianying's face wrinkled again:

"It is said that Pingyang County is a city surrounded by three forts, how could it be lost so quickly?"

"The enemy army has a lot of cavalry, and they cut off the connection between the forts and the city, so that the city was broken... It's just that Pingyang City was indeed lost a little faster, but according to the news from Yangshi County, the enemy's horses were not seen..."

Cai Zhenji frowned and told everything she knew, and then told her husband's decision:

"The Shangdang prefect wants to move the population of Lu County to Huguan, and my sister and sister Xianying..."

"My sister is going to Huguan too?"

"Of course I will go to Huguan with my husband, after all, General Gao and General Bao... Alas."

Cai Yan also knew that her sister's sigh was mostly due to the bitterness of Shangdang Prefect Yang Xin, and the reason was not a secret. She heard about it when she was in Yecheng.

After the Battle of Guandu, most of Yuan Shao's former subordinates joined Cao Xiang's camp. Although some of them were used and moved around, such as Zhang He, most of them were left idle after being given money, such as Gao Lan.

The main general of Shangdang was Gao Lan. Logically, Gao Lan and Yang Xin, one main general and one governor, could ensure that Shangdang was safe if they guarded Huguan and Luxian respectively.

But... there was also Bao Shao, who was at the same level as Gao Lan.

His father Bao Xin was an old friend of Cao Xiang. He responded to the call to fight against Dong, welcomed the governor of Yanzhou, and died to save Cao Xiang.

His brother Bao Xun is now a subordinate of the Prime Minister's Office and is now Cao Xiang's confidant.

Under such circumstances, the originally simple defense became much more troublesome.

In order to seek stability and to prevent conflicts between Gao Lan and Bao Shao, Yang Xin moved to guard Huguan and personally commanded the two, which became the only option.

Now that Governor Yang wants to move the people of Lu County to Huguan, it is obvious that he will probably station elite troops here. Then Cai Yan probably can't stay here. The only options are to go to Huguan together... or retreat to Yecheng.

Yecheng is very good, but the most memorable scene is the scene when she went to plead for Dong Si barefoot with disheveled hair and dirty face when Cao Xiang was entertaining guests, and the increasingly turbulent atmosphere in Yecheng after Cao Xiang was trapped in Jingyu.

Huguan is very dangerous, but my sister is there.

And... isn't Liu Bei's army known for its benevolence?

She didn't believe it before, but the books she read in the past two months made her believe it again.

Such a sensible and intoxicated person also worked for Liu Bei, so I think Liu Bei should not be too bad.

After thinking it over, Cai Yan also made a decision:

"Then I will go to Huguan with you."

"Since both sisters are going, I can only..."

Xin Xianying sighed, and before she finished her words, she was pushed away by Cai Zhenji:

"Then hurry up and pack up, Huguan is quite close, I will leave after noon."

"Hey, hey, hey, I haven't finished yet..."

After Xin Xianying was pushed through the Moon Gate, she saw Cai Zhenji walking away, and then asked Cai Yan, who was always calm beside her:

"Sister, do you know that Huguan..."

"Huguan is probably not defendable."

Cai Yan's expression did not change, but she still sighed lightly:

"Between Huguan and Pingyang, there are many mountains, which are beyond the reach of the cavalry. Therefore, the cavalry must go north through Wu County, Jinyang, around Yuci Zhan County, take the narrow road from Shi'a to Xiangyuan, and attack Shangdang directly. hinterland.”

Xin Xianying was shocked by these remarks, but he immediately remembered the experience of this sister being kidnapped. This place was also a frontier, so no wonder she was so familiar with it.

But since he knew so clearly, Xin Xianying was a little confused:

"Then sister..."

"But can you survive in Yecheng?"

Xin Xianying was also speechless, and there was an obvious hint of unwillingness on her face:

"If we were men, why would we be so homeless without knowing the end..."

In terms of city power in Shangdang, Huguan is the only one that cannot be compared with Lu County.

However, as the people of Yanghe moved to Lu County, the city was finally crowded. Fortunately, as members of the prefect's family, Cai Yan's three daughters could still find a quiet place to study.

Over the past month, the three of them occasionally talked about Shangdang County, which was now at war again.

Ji's County has been lost, and the bandit commander named Huang Quan has been fighting fiercely with Cao's army in Changzi County for several days. It is said that this infantry is composed of Yizhou's strong soldiers, and there are many people among them. These barbarians even Cao Jun is more adaptable to the terrain here than Shangdang's Cao Jun.

Cai Yan's guess was informed to Yang Di through Cai Zhenji. Now there are reports from Xiangyuan that Qiang cavalry scouts have appeared. It seems that the disappeared cavalry army really traveled nearly a thousand miles and tried every means to join the Shangdang.

But... "Cao Cheng has been fighting for years, and the Shangdang troops have been repeatedly mobilized. Now there are less than 6,000 soldiers available to fight."

Cai Zhenji's brows have become more and more worried in the past month. Even if her sister has judged Liu Beijun's movements, there is not much she can do with the few soldiers available.

After all, there are nearly five thousand enemy troops attacking from Pingyang in the west alone, and a cavalry army that can circumnavigate Xihe Taiyuan and attack thousands of miles is at least three to five thousand. In terms of numbers alone, Shangdang is already Disadvantages.

"My husband has been to Yecheng and written to me again and again, hoping..."

But thinking about what her sister said about a great chaos in Yecheng, Cai Zhenji couldn't tell what to look forward to.
