Regarding this painting of Zhuge Liang, Li Shimin understood it at a glance.

"Capture Xiahou Yuan in Yongliang instead of Hanzhong?"

"It's ...... time"

Fang Xuanling moved very quickly, and he had already calculated in an instant just now:

"It should be the seventeenth year of Jian'an, and Cao Cao's 400,000 army marched south to conquer Sun Quan in the mouth."

After being reminded, Li Shimin remembered, if he remembered correctly, according to the Three Kingdoms, Liu Bei should still be in Yizhou at this time.

As a result, he had already won a bloody battle with Cao's army in Yongliang and conquered Chang'an.

Li Shimin naturally understands the meaning:

If it weren't for Tongguan in his hand, the danger of Guanzhong had already been achieved, how could Wuhou paint so peacefully?

Cao Ju in the Central Plains, Liu Dingguanzhong, Jiangdong Remnants are insufficient, and this situation is probably very different from the record of the "Three Kingdoms".

Moreover, the defeat of Cao's army will only be a matter of time.

After all, this is a Zhuge Wuhou who has an overview of the whole picture of China.

In addition, Li Shimin is more interested in the side of Wuhou at this time, how much deviation will there be from the record of the Three Kingdoms?

Wait until the next light curtain to ask carefully!

According to the curiosity in his heart, Li Shimin took a deep breath, now that the light curtain has been extinguished, no matter how much he scratches his heart and liver, he can only wait for three months with peace of mind.

Before that, it is also necessary to pay more attention to the Tang Dynasty that will start the war in front of us.

It's just that...... Thinking about the scenery of Liu Bei and others climbing to Chang'an on the painting, Li Shimin actually felt a little proud in his heart.

Wuhou's views are very different, so the next battle of Tuyuhun in the Tang Dynasty should also be different!

After the light curtain slowly went out, the first to retire were the Yan brothers, or rather, the impatient Yan Lide.

Hurriedly rolled up the drawing paper, Yan Lide arched his hand at Li Shimin and left in a hurry.

There were many thoughts turning in his head, and before his legs stepped out of the Avatar Palace, he was already thinking about how many people would be needed to dig a pit and a lake, and where to choose?

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

Should the sketch of the mausoleum that I had studied at home be burned all at once?

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

After all, the Ganlu Hall also had a pestle with Imperial Doctor Sun, and it was fine at other times, but after I glanced at Imperial Doctor Sun just now, I always felt a little chill in my back.

Yan Liben believed in his instincts very much, and planned to follow his brother to slip away, either to help out with some merits, or to ask three or two friends to go outside Chang'an City to drink and have fun, in short, he couldn't afford to take a vacation.

"Your Majesty must remember to avoid eating and drinking."

Sun Simiao hurriedly admonished and then retreated, not forgetting to shout while speeding up:

"Yan Langzhong? Yan Langzhong! Why don't you go for tea with me? ”

"Why did Yan Langzhong run in a panic? Wait for me! ”

Seeing several people leaving noisily, Li Shimin also shook his head with tears and laughter.

Sun Yaowang has been diligent in his exploration of medical Taoism, and now that he knows the danger of the epidemic, he naturally does not need to be urged, but may need to find someone to take care of him, so that Sun Yaowang should not take risks to study the epidemic.

As for the place where I can help King Sun Yao, I have long been in mind.

Since Galen, a famous doctor in ancient Rome, could test medicine with apes, Datang naturally had no reason.

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

In addition to these things, Li Shimin turned his head and glanced at Fang Du and the others, who also gave up their hands to him.

After working together for many years, you only need to look at your expression, and then think about the words of the light curtain just now, Li Shimin has already understood:

"Xuanling Keming wants to find Li Chunfeng? Hurry up! ”

It's just that compared with Li Chunfeng, who was slightly impressed, Li Shimin sighed more about Liu Zhuo's experience.

Compared with the name of geniuses in later generations, if the early Tang Dynasty talks about this person, most of them only have one sentence of "madman" evaluation.

How can you not be crazy? During the reign of the emperor, this Liu Zhuo fought against the Confucians with his nationality, which made the Confucians of the Sui Dynasty annoyed and embarrassed, and jointly excluded them, and slandered Liu Zhuo and suffered the dethronement.

Later, in terms of opinions on the calendar, he openly criticized Zhang Xuanxuan, the Taishi Ling of the Sui Dynasty at that time, and the result was that he was finally deposed again after being drafted again.

Liu Zhuo, who was still not convinced, compiled this "Imperial Calendar" by himself, dedicated to the Sui Dynasty, and wanted to show his talents.

This calendar was indeed praised, but it was the "Great Cause Calendar" that was eventually adopted, and the main compiler of this calendar was none other than Zhang Xuanxuan, the Taishi Ling, who had been criticized by Liu Zhuo.

Under the repeated blows, coupled with the chaos in the world, Liu Zhuo was finally disheartened and closed his door to teach with all his heart, and finally became a generation of scholars.

And now that he heard that he was talking about the arithmetic talent of the great Confucian Liu Zhuo after a thousand years, Li Shimin also had mixed emotions in his heart, and after a little silence, he called out to Fang Du, who was about to walk out of the palace gate, and told again:

"Admonish Li Chunfeng and let him know the benefits of arithmetic."

The subtext is to ask Li Chunfeng to stop indulging in those yin and yang Taoist sayings, Fang Du and the others knew it, nodded and went out.

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

This arithmetic is so important that instead of placing it in the same place as other studies, it is better to make it a separate column to highlight its importance.

In this way, after a thousand years, the younger generations can recall that although Emperor Wu of the Han Dynasty pioneered Taixue to open a thousand-year-old style of learning, Taizong of the Tang Dynasty also pioneered the arithmetic pavilion to lay the foundation of science.

Just thinking about it made me quite moved, so another measure was quickly finalized in Li Shimin's heart.

Then the ministers dispersed in turn, and walked in pairs, most of which were also exchanging experiences from what they saw this time.

After all, what the light curtain 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 impossible to say, Li Shimin also understood.

The only thing that was a little difficult to do was Hou Junji, seeing that this former minister once again sobbed and promised to open the sea to the death, Li Shimin twisted his brows and was also slightly disgusted:

"What's the use of dying?"

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

Even though the Duke of Lu Guo of the Tang Dynasty was teary-eyed, he felt that His Majesty was really still nostalgic.

Then I heard Li Shimin say leisurely:

"After bringing what you see back to Chang'an, it's not too late to die."

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

But think about the Li Jiaerlang in history who ordered his beheading, his mood is a thousand times more uncomfortable than at this time?

This comparison was quickly relieved, and then he also moved his gaze to the last person left here: the champion Ma Zhou.

At this moment, Ma Zhou is still a little confused, in a short period of time, he has experienced the top of the list, the Chang'an street praise, the emperor summoned, watching the strange light curtain, knowing the eternal things, Ma Zhou now looks at the emperor of the Tang Dynasty and feels a little unreal.

Could it be that this is just a dream of a drunken Huangliang in the Razor Mansion? Otherwise, it is impossible to explain what we see today.

And Li Shimin smiled quite kindly, and he was familiar with this matter.

Personally dragging this champion who is said to be a famous minister of Zhenguan in the future, Li Shimin waved his hand heroically:

"Can King Bin know the prosperity of Zhenguan? Do you want to know your name? Do you want to know the rise and fall of the ages? ”

A series of three questions made Ma Zhou's head completely lose the ability to think.

And then Li Shimin did not hesitate to use a new statement he learned:

"Today's Zhenguan is a great change that I have not seen in China for 5,000 years! There is an urgent need for talents to devote themselves to leading the general trend and showing their talents. ”

"King Bin can be the talent of Zhenguan?"

……

Kong Ming laughed at the evaluation of his paintings by later generations, but sighed a lot about what happened to Liu Zhuo:

"Sui has Liu Zhuo, Han has Liu Hong, all of them are the victims of troubled times."

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

"What the military advisor said is Changshan Liu Yuanzhuo?"

Kong Ming nodded in confirmation, and turned his head and said:

"Xianhe."

So Liu Bei saw that Jian Yong's face was slightly complicated and he launched a small box, and after opening it, he saw a neat box of bamboo slips and a thin booklet on the top.

"Dry Elephant Calendar?" Liu Bei read out the name of the cover of this pamphlet with a puzzled expression.

Kong Ming didn't sell Guan Zi either, and immediately told the story.

"After entering Chang'an, Zhong Sili offered a collection of books for us to copy, so I asked Xianhe to come over to help, and found this thing when I copied more than half of the slips in Zhong Sili's collection."

"The "Four-Minute Calendar" has some flaws, people of insight know that when Emperor Xiaoling, Liu Yuanzhuo was recommended by everyone Cai Yongzhi to make a new calendar."

"Liu Yuanzhuo has been concentrating for many years, and finally produced this calendar, which is more than perfect compared to the "Four-point Calendar", and its arithmetic level far exceeds ours, which can be called unattainable."

Liu Bei was suddenly very curious:

"If so, how can I not hear of it?"

Kong Ming suddenly sighed again and said:

"In the sixth year of Zhongping, Emperor Xiaoling summoned Liu Yuanzhuo to Beijing, wanting to use the dry elephant calendar."

Hearing this, Liu Bei immediately understood everything.

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

And what happened this year can be described as dizzying:

Emperor Ling collapsed, the young emperor succeeded to the throne, He Jin was killed, the eunuchs were ambushed, Dong Zhuo was dictatorial, the princes raised troops, and the beginning of the troubled times began.

Compared with these things, Liu Yuanzhuo, who was summoned to Beijing, naturally no one cared, and the change of the calendar could only be stopped.

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

You can count the ability to reach the heavens, but what do you do when you are born in troubled times?

However, at this time, Liu Bei also lifted his spirits and said:

"As far as I know, Liu Yuanzhuo was appointed as the Taishou of Shanyang County, as long as I wait......"

Kong Ming shook his head regretfully to stop Liu Bei's posture of continuing to speak, and said:

"When he and Zichu were in Chengdu, they all collected the works of arithmetic, and the most commendable one was Liu Yuanzhuo's annotated "Nine Chapters of Arithmetic", and this sage can be called my teacher."

"After entering Chang'an, I learned from Zhong Sili that Liu Yuanzhuo had been dead for two years."

So Liu Bei could only sigh:

"Troubled times, troubled times."
