"That should be the case." Han Du nodded, but he didn't say too sure, but said with a guessing tone.

After a pause, Han Du continued: "Qin Tian Jian records various celestial phenomena, and the broom star is the most important thing they record. If there is detailed data on each appearance of the broom star, and Qin Tian Jian has the proficiency

Using math, it is not difficult to predict that a bad star will appear this year."

Lao Zhu was silent when he heard this, and suddenly looked at Han Du and said, "You are considered a master of mathematics, and now you have seen the broom star. Have you calculated when it will appear?"

Han Du nodded truthfully and replied: "I have calculated it."

"Oh?" Lao Zhu suddenly became curious and asked quickly: "When will the broom star appear?"

Han Du handed over his hands in shame and replied: "With my ability, I can only calculate that in ten to fifteen days, the broom star will appear in the sky. As for the specific day, I can't calculate it."

Standing up straight, Han Du continued: "However, the Crown Princess is a hundred times better at arithmetic than her ministers. If the Crown Princess is willing to take action, she may be able to accurately calculate the day when the broom star will appear."

"Han Jingyun?" Lao Zhu nodded in agreement. He was not dissatisfied at all with Han Jingyun, his daughter-in-law.

Lao Zhu turned around and glanced at Zhu Biao. Zhu Biao immediately understood and said: "When my son returns, he will tell Jing Yun that he will go home to visit relatives tomorrow." Going home to visit relatives is a rare opportunity for women who have entered the palace to relax.

.Although Han Jingyun would come back from time to time, she would not refuse such an opportunity.

When Han Du heard this, he nodded to Lao Zhu and said that when the girl comes back tomorrow, he will help her calculate the time when the broom star will appear.

Lao Zhu nodded with satisfaction, and suddenly saw the clear brilliance of the bright moon above his head. He looked up at the moon and said, "Didn't you say that this telescope can still see the moon clearly? I just wanted to take a look."

"Your Majesty, please." Han Du stepped forward and began to teach Lao Zhu how to use the telescope to aim at the target.

Even though the moon was very big, Lao Zhu worked hard for a long time before aiming at the moon under Han Du's persuasion. Only then did he realize that Han Du was really half lucky to be able to find the trace of the broom star.

Lao Zhu looked down at the mirror again, and after just one glance, Lao Zhu couldn't help but said: "How could this be?"

The moon that catches the eye not only does not feel as bright as a white jade plate, but instead gives people a devastated scene, just like what Anqing said.

When Zhu Biao heard this, he couldn't help but feel curious and asked: "Father, can I have a look?"

When Lao Zhu saw the true face of the moon, all the good expectations in his heart suddenly burst like bubbles. The longing in his heart was gone, and he even saw a hint of darkness. Lao Zhu suddenly lost the desire to continue watching.

He straightened up, took two steps back, and gave the place to Zhu Biao.

Sure enough, as Lao Zhu expected, Zhu Biao couldn't stand it after just one glance.

"What on earth is going on? How did the moon become like that?" Lao Zhu raised his hand and pointed towards the bright moon, looking at Han Du in confusion.

Han Du smiled bitterly when he heard this. Do I still have to explain to you the craters made by the meteorites? He had no choice but to say: "Your Majesty, this is what I saw when I saw it. Maybe this is the original appearance of the moon."

"Is this the true face of the moon?" Lao Zhu shook his head and said nothing more.

Just at this time, An Qing climbed up to the attic and walked in. He went up and took Lao Zhu's arm and said: "Father, you have been here for so long, you must be starving. I have ordered people to prepare.

Now that we’ve got wine and food, why not go down and have some food first?”

"Okay." Lao Zhu smiled and patted An Qing's hand, nodding without any hesitation.

An Qing was overjoyed when he heard this. He helped Lao Zhu and turned around and walked towards the attic, "Father, be careful where you step."

Han Du looked at Lao Zhu who was about to disappear at the door and asked quickly: "Your Majesty, then" he brought Lao Zhu here not to watch the moon or eat, but for a purpose.

Lao Zhu paused for a moment and said without looking back: "You can wait until you calculate the time when it will appear." After that, he followed An Qing and walked down.

.

Seeing that Han Du was a little disappointed, Zhu Biao stepped forward and patted his arm, comforting him: "Let's go, don't worry, I will also speak for the Duke of Han*."

The next day, Han Jingyun was told by Zhu Biao that she could go home to save her bride, and she jumped up and down with joy. She immediately ordered her maids and female officials to prepare everything, threw Zhu Biao behind, and headed towards the house without stopping.

Zhenhaihoufu rushed over.

The arrival of Han Jingyun made Han De very happy.

However, after dinner, Han Du found his sister and told her: "It is the emperor's will that you go home to visit your relatives this time."

Han Jingyun was stunned when he heard this, and asked with some confusion: "Isn't it just the prince's consent? How come I went home and asked His Majesty to issue an order?"

So, Han Du told his sister exactly what happened.

After hearing this, Han Jingyun was not angry, but became very excited. He stood up and walked around twice in front of Han Du and said, "However, I have never calculated such a problem. I don't know if it will work."

"If you can't do it, no one in the world can do it. Come on, I'll take you to have a look." Han Du didn't waste any time and took Han Jingyun directly to the attic.

After she saw the telescope and the broom star, she told her the problem of calculating the broom star.

After hearing this, Han Jingyun didn't ponder for long, then nodded and said: "It sounds a bit complicated, but it's not impossible to calculate. Brother, although your calculation method is feasible, the error is too big. Let me think about it, wait for me

There should be no problem if we rebuild a mathematical model."

Han Du was assisting Han Jingyun on the side, and there were some astronomical knowledge that Han Jingyun didn't understand, such as the orbital shape of stars, the speed changes of stars when they orbit, etc.

Just one day later, Han Jingyun calculated the exact time when the Broom Star appeared. Not only that, she also integrated the existing trajectory of the Broom Star into the star chart and calculated the celestial phenomena caused by the Broom Star one by one.

After finishing, Han Jingyun added, "It's a very simple thing, how come you can't figure it out, brother?"

What else could Han Du say? He could only lower his head and pretend not to hear the girl's words, and took away the note in front of her with one hand.

Han Du took the results calculated by Han Jingyun and immediately entered the palace.

Lao Zhu took the note, stood up, walked around, and read: "At three o'clock in the hour of the fourteenth day, the star will be seen in the northeast of Wuche. Sweep the inner steps and enter the Ziwei Palace. Sweep the five stars in the North Pole to offend Dongyuan Shaozai. Enter

Tianshiyuan violates Tianshi."

After he finished reciting, Lao Zhu's face suddenly turned bad.

The reason why Lao Zhu looked so bad was because of the information on the note. Originally, Lao Zhu just thought that the broom star appeared this time, just like what the Qintian Supervisor reported, and there were important ministers to deal with the problem. But now after reading Han Jingyun's calculations,

When the results came out, Lao Zhu's face darkened.

Entering the Ziwei Palace, this is a polite way of saying it. What is the unkind way of saying it, it is called violating Ziwei. The Ziwei Star Palace represents the emperor. Corresponding to the present, it is Lao Zhu. And violating Ziwei, if it is according to the induction of heaven and man.

The theory is that there will be disasters in the world that impact the emperor. If one mistake is not made, the emperor may die and the dynasty may fall.

This is far from being comparable to an important minister responding to a difficult situation.

Sweeping the five stars in the North Pole, that is to say, if this celestial phenomenon is true, then not only Lao Zhu is in danger, but even the entire Ming Dynasty is in danger.

As for other crimes such as committing crimes against Dongyuan Shaozai, entering Tianshiyuan, committing crimes against Tianshi, etc., compared with the previous two, they are all childish.

But now that the Ming Dynasty is booming, what power, or who can make the Ming Dynasty overthrow? It's not that Lao Zhu is arrogant. He thought about it carefully, but he really didn't expect anyone to be able to do it.

The biggest threat to the Ming Dynasty is Meng Yuan in the north. However, since Meng Yuan was annihilated by Lan Yu in the imperial court, the group of dragons has been leaderless and turned into a mess. In addition, with the frontier kings and Lan Yu, Fu Youde guarding it, in the past two years, even Meng Yuan has been

There is no such thing as disturbing the border, let alone going south to detain customs.

.

On the contrary, in the past two years, the Ming Dynasty would go deep into the grassland every spring when the vegetation grew, to clean up and suppress the Mongolian Yuan.

As for the capital, Lao Zhu doesn’t have to worry. Nearly half of the Ming Navy’s troops are here

Stay in the capital.

Moreover, some of the garrison in the capital were already equipped with revolvers. Lao Zhu really couldn't think of anyone who could invade Ziwei.

I thought so, but just in case, Lao Zhu spread the note in his hand, raised his head and asked Han Du: "What do you think?"

Han Du suddenly laughed and said: "Your Majesty, this is just a celestial phenomenon. It has nothing to do with the so-called celestial telepathy or celestial warning. In the history books, there are not many records of such celestial phenomena, and some of them are included in Ziwei.

time, but the world is still a peaceful and prosperous time. It can be seen that the theory of the induction of heaven and man is simply untenable."

After hearing this, Lao Zhu finally laughed slowly and said, "Yes, this is just a celestial phenomenon." ??

Shaking his head, Lao Zhu casually threw the note on the imperial desk and sighed: "But I think so, and so do you, but the people of the world may not think so too."

Lao Zhu immediately grasped the key to this matter. This matter can be said to be big or small. The key to the big or small lies in how the people of the world will view it.

If the people all over the world feel that the world is peaceful and the broom star is just walking around in this world, then everyone will naturally be happy. But if the people think this is a sign of chaos in the world, then Lao Zhu is not afraid. But he is worried that the ignorant people will be taken advantage of by people with ulterior motives. Once trouble occurs,

After all, it was Ming Dynasty and Zhu Yuanzhang who lost.

Han Du thought for a moment and said, "Your Majesty, I have an idea."

The reason why Lao Zhu said that just now was that, firstly, he had such worries in his heart, and secondly, he wanted to see if Han Du, who had always been resourceful, could think of a solution.

Seeing that Han Du said what he expected, a smile suddenly appeared on his face, he nodded and said, "If you have any good ideas, tell me quickly."

After Han Du smiled, he pondered and said: "It's not a good idea, but I feel that since the people don't understand that this broom star is a celestial phenomenon, it doesn't mean anything. Then why don't we let the people know?

"

"Oh? Is there any way you can make the people agree that this is an ordinary celestial phenomenon?" Lao Zhu asked curiously.

Han Du smiled and pointed at the note on the imperial case and said: "Isn't this a ready-made method? The broom star has not yet appeared. If we can let the people see it, the court can accurately predict the appearance of the broom star.

, and even how long it appears can be calculated clearly. This unveils the mystery of the broom star. Without this mystery, the broom star is just a star to the common people, just like the moon above their heads.

That’s all.”

When Lao Zhu heard this, the sadness on his face suddenly melted like ice and snow, he nodded slightly and said with a grin: "It's not a bad idea."

Seeing Lao Zhu nodding in agreement, Han Du said nothing more.

"Then I'll leave this matter to you." Lao Zhu waved his hand, and the matter fell on Han Du.

Han Du suddenly coughed twice.

Lao Zhu suddenly frowned and looked at Han Du, and asked with some dissatisfaction: "What? Are you still not happy?"
