She married a dying prince and she won three babies.

Shangguan Ziqi followed Master Huihai into the imperial study again.

"Amitabha, I greet the Emperor."

"Master Huihai, please don't be so polite. I wonder why you have come to the palace to see me?" the emperor asked directly.

I also took a look at Shangguan Ziqi.

As soon as he saw Shangguan Ziqi come in, he guessed that what the old monk was going to say might be related to Prince Rong's Mansion.

"Your Majesty, Master Mingwu, who was traveling from the Huguo Temple, wrote letters back to me. Among them, there is a letter specially written to Your Majesty. Please take a look." Master Huihai took out a letter with fire knees on it from his sleeve pocket and handed it to the emperor respectfully.

"Oh? A letter from Master Mingwu to me?" The emperor was even more puzzled.

Master Mingwu is already eighty years old. He is a highly accomplished monk in Huguo Temple and also the oldest monk.

A hundred years ago, the third generation Prince Rong and Master Puxian of Huguo Temple were good friends. They often played chess together in the meditation room of Huguo Temple, and would play for a whole day.

This matter is recorded in the royal family files.

But I don’t know what the two of them talked about while playing chess.

At that time, Master Samantabhadra was already fifty years old.

When he was in his seventies, he accepted a closed disciple, Master Mingwu.

It can be said that he is the person who is still alive and has the closest relationship with the third generation Prince Rong.

The emperor took the letter and read it in front of the two of them.

As his eyes moved across the letter, the emperor's expression gradually became brighter and brighter.

At the end he even burst out laughing.

"Good, good, good."

"Your Majesty, is this a happy event?" Shangguan Ziqi was happy too when he saw the emperor so happy.

"Hui Hai, Zi Qi, this is really good news. Master Ming Wu wrote in a letter saying that he recently had a fortune-teller tell him that someone in Wei could open the iron box, and that person is in Prince Rong's mansion.

Canglan must hold steady in this battle with Dawei, and then launch a massive counterattack after opening the iron box. They will surely win and gain peace for another fifty years or even longer.

You must keep this matter secret and not tell anyone, otherwise it will attract spies from the Canglan Kingdom to assassinate you."

The emperor was truly happy.

The iron box that the old Prince Rong and his wife made had a code on it, saying that only the right person could open it.

There are no clues left, and only the right person can open it.

The agreement signed by the Emperor and Prince Rong with the Canglan Kingdom was that the two countries would not engage in large-scale war for fifty years. However, fifty years had long passed, and in the following fifty years, the Canglan Kingdom had frequently provoked the Wei Kingdom, but was afraid of the iron box, so it did not invade on a large scale.

There have been many wars, both large and small, over the past fifty years, but at most only about 50,000 troops have been deployed.

The Wei Dynasty had a large population, and always relied on its numbers to repel the enemy.

Shangguan Ziqi's eyes lit up when he heard this, and then he frowned again.

Now there is only the eldest branch of their family left in the palace. Could it be that the second branch was kicked out?

If that's the case, it would be better not to know the news.

"Did Master Mingwu say who can open it?" Shangguan Ziqi had to find out.

"Master Mingwu didn't say. He said that he might be able to return to Huguo Temple in about a month, and then he will come to the palace to visit." The emperor was also helpless.

The person is not in Beijing, so I can't find him and ask him properly.

"Hui Hai, do you know where Master Ming Wu is now?"

"Your Majesty, I don't know. The letter was sent back by a courier company. They brought it back from the southwestern border town. However, Master Mingwu is a wanderer and has no fixed place. If he were to go there now, he would probably have already left."

"Well, I hope he can return to Beijing soon. In that case, Ziqi, you should take the iron box back to the palace today." The emperor thought for a while and made a decision.

The last time Cao Jinyu brought the fake one back to Beijing, he spread the news that the iron box had been found.

Then the emperor asked to bring it into the palace for safekeeping.

In order to make the news reliable, the prince took out all the fake ones and sent them to the palace together, including the real one.

In this way, the enemy's spies can immediately determine whether the news is true or false.

There were five fake spies from Canglan Country, and Prince Rong sent six of them into the palace at once, so the real ones must be among them.

The news spread quickly to Canglan, so the attack of Canglan Kingdom slowed down because the real iron box was found.

They dared not advance further after capturing just one city.

Just a provocation from time to time.

"Yes, thank you Your Majesty."

The emperor asked Eunuch Hai to bring all six iron boxes to the imperial study.

He was testing whether he could recognize the real one from six at a glance in endgame.

But the emperor himself couldn't tell the truth from the false.

The five fake ones are made to look just like the real ones.

But Shangguan Ziqi only needs to weigh each piece in his hand to know which one is the real one.

He has been playing it since he was a child and is very familiar with it.

"Are you sure the one you chose is the real one?" The emperor was very skeptical.

"If the emperor doesn't believe it, you can ask someone to open all of them. I can guarantee with my own life that those are fake." Shangguan Ziqi was very confident.

If they can't even divide the ancestral treasures of the Rong Prince Mansion, how can they be considered the direct descendants of the Rong Prince Mansion?

Shangguan Ziqi returned to the palace with the iron box in a somewhat distracted state.

The prince was also at home at this time.

I saw my son bring that thing back.

Ask why.

Shangguan Ziqi then told him what happened in the palace.

The prince also fell into deep thought.

Is there anyone who can open the palace?

Who?

Zishu and Chaoyang have tried countless times without any results, so it definitely can't be them.

It is even more impossible to play chess from childhood to adulthood.

And the same goes for himself.

"Has your wife tried it?" the prince asked after thinking for a while.

"I played with it in the first few days after I found it." Shangguan Ziqi answered truthfully.

Needless to say, the result was that it was definitely not opened, otherwise he would have told it long ago.

"Put it in the main courtyard first, and have your wife bring the children there often to play with their aunt. Put the iron box in the living room and let the children play with it. Maybe they'll open it by chance one day.

The prince has wild ideas.

Shangguan Ziqi wanted to roll his eyes after hearing this. What's the difference between this and taking a chance?

They have tried this kind of thing countless times over the generations.

Now the father has applied this tradition to several children who are just over one year old.

Fortunately he could figure it out.

"Father, isn't this too much of a joke?"

"Then what good ideas do you have? Master Mingwu hasn't come back yet. You don't know who can open our palace. Now only the four children have not played." The prince said as a matter of course.

"Okay. Father is right." Shangguan Ziqi couldn't refute it.

"Has mother ever tried it?" Shangguan Ziqi suddenly thought of this and asked.

"Your mother tried it when she first married into the palace, but she couldn't open it, so she never touched it again."

"Then let mother try a few more times."

"Okay. Just leave it there and let your wife try it out."

Neither the father nor the son thought of letting the Nanhua County Lady try it as well.

Until now, Nanhua County Lady had never touched the iron box. She had only seen it in Yu Chaoyang's courtyard.

Shangguan Ziqi returned to Qiyayuan and saw Yu Yuanzheng, Ding Huiniang and Ziyue feeding the three children.

My heart softened immediately.

At night, the two washed and lay down.

Yu Yuanzheng looked at Shangguan Ziqi with a mysterious smile.

"Madam, why are you looking at me like that? Are you thinking about something?" Shangguan Ziqi smiled with amorous feelings.

"Go away, you're the one who wants it. I have something to tell you." Yu Yuanzheng pinched him.

"Madam, if you have any instructions, just tell me. I will definitely agree to it." Shangguan Ziqi grabbed her dishonest hand.

"Is this what you said?"

"I said it." Shangguan Ziqi doted on his wife so much that he agreed without even knowing what was going on.
