The queen died unjustly and was reborn as the empress.

After taking their seats, everyone craned their necks to look at the paper in Prince Di Yun's hand.

"A thousand-year question, what on earth is this? A poem? Or what?"

Prince Di Yun shook his head and sneered, "We in Quan Kingdom don't play with literate poetry."

These words seemed like a rejection, more like a provocation, implying that Ning Guo had done something useless and elegant.

Someone below was unhappy, "Oh, it took ten years to come up with a solution? This can only mean that your abilities have reached the limit."

Prince Di Yun was not angry, and chuckled, "If Ning Guo can solve this problem, I will sign a treaty of eternal friendship between the two countries, and Ning Guo will always come first."

The audience was in an uproar, this sounded too tempting.

Everyone knows that Ning State seems to be a powerful country, but with Quan State in the south and Jiang State in the north, it can be said that it is attacked from both sides. Quanguo seems to have surrendered to Ningguo, but its ambitions have not changed. Especially after the recent changes in Jiangguo, Quanguo is even more ready to attack at any time.

"But if you can't untie it, it means you don't have the power, and there is no need for us to surrender." Di Yun looked proud, and it seemed that he was destined to win this trip.

Yun Qin smiled and said, "Prince Di Yun, you must keep your word and don't cry and regret it when the time comes."

Di Yun ignored it and raised the paper in his hand.

"The problem-solving rules have been written on the paper. Please read it carefully."

Emperor Tianxuan's eyes were deep and he nodded towards Zhang Zhong.

Zhang Zhong understood and walked down to take the paper from Prince Di Yun's hand and presented it to Emperor Tianxuan.

Emperor Tianxuan looked at the paper in his hand with half-squinted eyes, and the color gradually darkened. It seemed that this question was difficult to solve.

"Everyone, come and take a look. I will reward the one who solves the problem."

Zhang Zhong took the paper from Emperor Tianxuan's hand and started passing it down from Yun Qin's end.

Yun Qin got the paper and read it carefully. After a quarter of an hour, the problem was still not solved.

His face was getting darker and darker, his brows were getting tighter and tighter, "Humph! Could it be that the prince couldn't untie it himself and used it to fool us?"

Di Yun smiled and ignored him, but turned his eyes to look at Yun Ye. "I heard that the three palaces of Ningguo's God of War are both civilized and military, so why not come and solve this problem?"

In his eyes, what does Yunqin mean? The only one they feared was Yun Ye, His Highness the Third Prince of Ning Guo, who was known as the God of War. They didn't get any benefits on the battlefield before, but today they were embarrassed on the spot.

Yun Qin angrily handed the paper to Yun Ye, very unconvinced, "I, Wang Ka, don't understand, but my third brother still wants to read it?"

Bai Lan turned her head, huh, what a narcissist. "Second brother, you are you and he is him. You two look different."

This means that if they look different, their brains will naturally be different, let alone their IQs.

Yun Qin turned his head away in anger. He didn't want to talk to Bai Lan and was annoyed by her voice.

Yun Ye leaned on his wheelchair and lazily took the paper from Yun Qin's hand. He only glanced at it and handed it to Bai Lan, "I am not interested in this kind of digital game." After saying that, he handed the paper to Bai Lan's hand.

Bai Lan took it and understood it at a glance. Isn't this the advanced version of Sudoku? The basic version of Sudoku has nine squares, and this one has ninety-nine and eighty-one squares.

It seems to be complicated, but in fact it is simple as long as you understand the principles.

She didn't say anything, just passed the paper down with disdain.

Yun Ye was puzzled and wanted to ask a few questions, but received a reassuring look from Bai Lan. He understood immediately and said no more, silently watching others pass the paper on.

The paper was passed down one by one, and everyone shook their heads helplessly and dejectedly. Finally, it was passed back to Zhang Zhong. Zhang Zhong glanced at the title on the paper. Oh my god, this is a maze. . With so many grids, how can we arrange them from 1 to 9 horizontally, vertically and diagonally without repeating them?

Emperor Tianxuan sighed and looked at Bai Lan with pleading eyes. Even she had nothing to do, so was it really impossible?

The moment he looked up, he met Bai Lan's calm eyes, and his heart moved, did Lan'er have another plan?

Di Yun was proud, "I didn't expect that in this huge country, there is no one who can come out to solve the problem. If this is the case, what reason does it have for us to surrender willingly?"

In the hall, everyone lowered their heads and remained silent. The person who had just spoken nonsense was even more anxious. If I had known, I wouldn't have said much just now. This question is really a thousand-year problem.

From the side of the hall, a melodious voice sounded, "Haha, I can't believe it. You, Quanguo, spent ten years thinking hard before you came up with this thing? In the past ten years, we, Ningguo, have made countless sophisticated weapons. "

Yun Ye burst into laughter, "My daughter-in-law doesn't know something. This is the gap between our two countries, and that's why we have always been the big country they look up to."

Below, General Pingnan laughed without any scruples.

Di Yun snorted coldly, "I wonder who this is..."

"He is my king's concubine."

"Oh, it's Princess Ye, I'm sorry." Di Yun leaned forward slightly and saluted with a smile.

"Princess Ye just said that this Thousand-Year-Old Question is this thing? What does Princess Yi mean that there is a solution? Even the person who created the question can't solve it. Are you so confident?"

"I can solve your problem, but can you solve mine?"

Di Yun became interested and said, "On this trip, the king has brought with him the smartest masters in Quan Kingdom, the three people who created the fourth title. If the princess is so elegant, why not bring them out to discuss and learn from each other."

Behind Di Yun, three old men with long beards walked out, each with white hair and white beards, and their faces were full of red.

Well, at this age, no wonder he spent ten years thinking about the topic. He deserved to suffer. She really doubted whether these three old men were sent by Emperor Tianxuan to deliberately trick them.

"It's okay to discuss, but I have requirements." Bai Lan looked at Emperor Tianxuan who was sitting in the seat.

Emperor Tianxuan was satisfied and hummed, "Yes, if you can make demands, we will naturally make demands too. So, if you can't solve the princess's problem, how about you donate your three mines?"

Di Yun answered without thinking, "Okay! If I can solve it, how about asking the emperor to show his sincerity and carve out three provinces?"

Emperor Tianxuan was stunned for a moment. If Di Yun was so confident, could he have really brought some immortal master to challenge him? This was the first time he lost confidence in Bai Lan. Can Lan'er girl be one on three? If we lose, it will be a small matter to save face, but a big matter to seize the city.

The reason why Ningguo is strong is not only because of its strong military, but also because the states and cities are united as one. If three states and cities are defeated because of a little game, if word of this spreads, Ningguo will definitely have internal troubles.

Emperor Tianxuan was thinking when he heard Bai Lan's voice: "Father, please rest assured, my daughter-in-law will not disappoint you."

Emperor Tianxuan wanted to find a way to get rid of this matter, but before he could speak, Di Yun jumped in and said, "The princess is very impressive. In that case, please come up with your topic."

Bai Lan took his time and took out a square object from his cuff, with a total of six colors. "This is called a Rubik's Cube. It is similar to your topic and has certain rules."
