Spoiling History: Starting from the Three Kingdoms

Li Shimin understood at a glance that this painting was signed by Zhuge Liang.

Capture Xiahou Yuan in Yongliang instead of Hanzhong?

This time...

Fang Xuanling moved very quickly. He had already calculated in his mind and said:

It should be that in the 17th year of Jian'an, Cao Cao's 400,000-strong army marched southward and Sun Quan was defeated at Ruxukou.

After being reminded, Li Shimin remembered that if his memory was correct, according to the Chronicle of the Three Kingdoms, Liu Bei should still be in Yizhou at this time.

As a result, he had a bloody battle with Cao Jun in Yongliang and won, and captured Chang'an.

Li Shimin naturally understood the meaning:

If Tongguan was not in hand and the natural danger in Guanzhong was already there, how could Marquis Wu be able to paint so peacefully and leisurely?

Cao was in the Central Plains, Liu Ding was in Guanzhong, and Jiangdong was not enough to say that the situation was probably very different from the records in Three Kingdoms.

Moreover, the defeat of Cao Jun will only be a matter of time.

After all, this is Zhuge Wuhou who has an overview of China.

In addition, what Li Shimin is more interested in is how much deviation will there be between Wuhou's side at this time and the records in the Three Kingdoms?

Be sure to ask carefully until the next light curtain!

Suppressing the curiosity in his heart, Li Shimin took a deep breath. Now that the light curtain has been extinguished, he can only wait in peace for three months no matter how much he scratches his heart.

Before that, we still need to pay more attention to the Tang Dynasty, which is about to start a war.

Just... thinking about the scene in the painting of Liu Bei and his men ascending to visit Chang'an, Li Shimin actually felt a little proud in his heart.

Marquis Wu's views were completely different, so the subsequent Battle of Tuyuhun in the Tang Dynasty should also be different!

After the light curtain slowly extinguished, the first to retire were the Yan brothers, or to be more precise, the impatient Yan Lide.

After hastily rolling up the drawing paper, Yan Lide cupped his hands in front of Li Shimin and left in a hurry.

Many thoughts were running through my head. Before my legs even stepped out of the Manna Hall, I was already thinking about how many manpower would be needed to dig a hole to create a lake and create a river, and where would be the best place to do it?

The pressurized water well is simple to make, but what kind of material can be used to ensure that it is cheap and durable?

Do you want to burn all the sketches of the mausoleum that you have been working on at home?

Yan Liben on the side chose to sneak away quietly with his brother.

After all, Ganlu Palace had beaten up Dr. Sun. It was fine at other times, but just now I had a cold feeling on my back after taking a look at Dr. Sun.

Yan Liben believed in his instincts and planned to sneak away with his brother, either to help him get some achievements together, or to meet up with a few friends to go drinking and having fun outside Chang'an City. In short, he couldn't waste his vacation.

Your Majesty must remember to eat and drink.

Sun Simiao hurriedly warned him and then left immediately. He quickened his pace and never forgot to shout:

Mr. Yan? Mr. Yan! Why don't you come with me to drink tea?

Why is Mr. Yan running in panic? Wait for me!

Seeing several people leaving noisily, Li Shimin shook his head in confusion.

Sun Yaowang has always been diligent in researching medical knowledge. Now that he knows the danger of the epidemic, he naturally does not need to be urged. On the contrary, he may need to find someone to look after him so that Sun Yaowang does not take risks to study the epidemic.

As for the place where he can help Sun Yaowang, he has already kept it in mind.

Since Galen, the famous doctor in ancient Rome, could test medicine with apes, there was no reason why the Tang Dynasty could not do the same.

There are so many apes in Jiannan Road, just send people to catch them.

Apart from these things, Li Shimin turned his head and glanced at Fang and Du, who also bowed to him.

We have worked together for many years, and Li Shimin already understands just by looking at his expression and thinking about what the light curtain said just now:

Xuan Ling Keming wants to go find Li Chunfeng? Go quickly!

But compared to Li Chunfeng, who was slightly impressed, Li Shimin sighed more at Liu Zhuo's experience.

Compared with the reputation of genius in later generations, if people talk about this person in the early Tang Dynasty today, they will probably only comment on him as a madman.

How can you not be crazy? During the reign of Emperor Kaihuang, Liu Zhuo used his nationality to fight against the Confucian scholars, which made the Confucian scholars in the Imperial Academy of the Sui Dynasty angry and expelled him. Liu Zhuo was deposed due to slander and ridicule.

Later, in terms of opinions on the calendar, he openly criticized Zhang Zhouxuan, the Taishi of the Sui Dynasty at that time. As a result, he was finally recruited and deposed again.

Still dissatisfied, Liu Zhuo compiled the Huangji Li on his own and dedicated it to the Sui Dynasty in order to show off his talents.

This calendar was indeed praised, but in the end it was the Daye Calendar that was adopted, and the main compiler of this calendar was Zhang Zhouxuan, the Taishi Ling who was criticized by Liu Zhuo.

After repeated blows, and with the chaos in the world becoming apparent, Liu Zhuo finally became disheartened and closed his doors to teach with all his heart. In the end, he became a great scholar of Confucian classics.

But now that he heard that the great scholar Liu Zhuo's arithmetic talent was discussed a thousand years later, Li Shimin also had mixed emotions in his heart. After a moment of silence, he called out to Fang Du who was about to step out of the palace, and warned him again:

Li Chunfeng should be warned and made aware of the benefits of arithmetic.

The subtext was to tell Li Chunfeng to stop indulging in those Yin-Yang Taoist theories. Fang and Du knew this, so they nodded and went out.

Looking at the direction in which the two important ministers were leaving, Li Shimin suddenly had an idea:

This arithmetic is so important that instead of placing it in the Imperial Academy alongside other studies, it is better to promote it and list it separately to show its importance.

In this way, after a thousand years, future generations can recall that although Emperor Wu of the Han Dynasty pioneered Taixue and established a thousand-year academic style, Emperor Taizong of the Tang Dynasty also pioneered the Arithmetic Pavilion to lay the foundation of science.

Just thinking about it made him very moved, so another move was quickly finalized in Li Shimin's mind.

Then the ministers dispersed one by one and walked together in twos and threes. Most of them were exchanging their experiences about what they had seen.

After all, what the light screen saw this time was shocking to them, especially this time there was a lot of news about ancient Rome. If they didn't discuss it privately to express their feelings, it would be unreasonable, and Li Shimin understood.

The only one who was slightly difficult to deal with was Hou Junji. Seeing this former close minister crying again and promising that he would fight to the death, Li Shimin frowned and showed a little disgust:

What's the use of dying?

If something unexpected happens, you should put your survival first!

Duke Lu of the Tang Dynasty burst into tears, feeling that His Majesty was indeed nostalgic for the past.

Then I heard Li Shimin say leisurely:

After taking what you see back to Chang'an, it's not too late to fight to the death.

In the end, Duke Lu of the Tang Dynasty was a little distraught when he left, which made Li Shimin a little unbearable when he was watching.

But think about the Erlang of the Li family who ordered his beheading in history. His mood is a thousand times more uncomfortable than it is now.

After such a comparison, he quickly felt relieved, and then he turned his attention to the last person left here: Ma Zhou, the number one scholar.

At this moment, Ma Zhou is still a little confused. In a short period of time, he has experienced being ranked first in the imperial examination, paraded in Chang'an to praise his name, being summoned by the emperor, watching the strange light curtain, and learning about the events of the past. Ma Zhou now feels a little confused when he looks at the emperor of the Tang Dynasty. It doesn’t feel real anymore.

Could it be that this was just Huang Liang Yimeng who was drunk in Lei Zegong's mansion? Otherwise, there is really no way to explain what I saw today.

Li Shimin smiled very kindly and was very familiar with this matter.

Li Shimin personally held the champion, who was said to be a famous official in Zhenguan in the future, and waved his hand boldly:

Your Majesty, do you want to know the prosperity of Zhenguan? Do you want to know your posthumous name? Do you want to know the rise and fall of the ages?

Three questions in a row made Ma Zhou's head completely lose the ability to think.

Then Li Shimin did not hesitate to use a new saying he learned:

Today's Zhenguan is a major change that has not happened in China for five thousand years! We are in urgent need of talented people to devote themselves to leading the trend and show their talents.

Is Prince Bin a talented person from Zhenguan?

…

Kong Ming laughed off later generations' comments on his paintings, but instead lamented Liu Zhuo's experience:

There was Liu Zhuo in the Sui Dynasty and Liu Hong in the Han Dynasty. They were both victims of troubled times.

Kong Ming's sigh aroused the curiosity of others, but Liu Bei thought about it for a moment and said uncertainly:

The military advisor is talking about Changshan Liu Yuanzhuo?

Kong Ming nodded to confirm, turned his head and said:

Xianhe.

So Liu Bei saw Jian Yongye pushing out a small box with a slightly complicated expression. After opening it, what he saw was a neat box of bamboo slips and a thin booklet placed on top.

Qianxiang Calendar? Liu Bei read out the name on the cover of the booklet with a puzzled look on his face.

Kong Ming didn't show off, and immediately spoke out.

After entering Chang'an, Zhong Sili offered his collection of books for us to copy, so I asked Xianhe to come over for help. I discovered this thing when I was halfway through copying the slips in Zhong Sili's collection.

The Four Points Calendar has flaws, which are known to all knowledgeable people. During the reign of Emperor Xiaoling, Liu Yuanzhuo was recommended by Cai Yong, who wanted to make a new calendar.

Liu Yuanzhuo worked hard for many years and finally produced this calendar. It is more perfect than the Four Points Calendar. Its arithmetic level is far beyond our level and is unmatched.

Liu Bei was immediately curious:

If it can be like this, how come I haven't heard of it?

Kong Ming immediately sighed again and said:

In the sixth year of Zhongping, Emperor Xiaoling summoned Liu Yuanzhuo to Beijing in order to collect the Qianxiang calendar and use it.

Hearing this, Liu Bei immediately understood everything.

The sixth year of Zhongping was an extremely special year for the Han Dynasty, because it was also the first year of Guangxi, the first year of Zhaoning, and the first year of Yonghan.

What happened this year is dizzying:

Emperor Ling died, the Young Emperor succeeded to the throne, He Jin was killed, the eunuchs executed him, Dong Zhuo became dictatorial, and the princes raised their armies. This was the beginning of the troubled times.

Compared with these things, naturally no one paid much attention to Liu Yuanzhuo who was summoned to Beijing, and the change in the calendar could only be ignored.

And now Liu Bei, who knows the importance of arithmetic, sighs frequently. What Kong Ming said is really right.

No matter how great you are in mathematics, what can you do if you live in troubled times?

But at this time Liu Bei also cheered up and said:

As far as I know, Liu Yuanzhuo will later serve as the prefect of Shanyang County. As long as I wait...

Kong Ming shook his head with regret and stopped Liu Bei from continuing, saying:

When I and Zichu were in Chengdu, I read all the works on arithmetic. The most commendable one is Nine Chapters on Arithmetic annotated by Liu Yuanzhuo. This sage can be called my teacher.

After entering Chang'an, I learned from Zhong Sili that Liu Yuanzhuo had passed away two years ago.

So Liu Bei could only sigh:

Troubled times, troubled times.
