The queen died unjustly and was reborn as the empress.

The Rubik's Cube in your hand has six sides in six colors, and each side is composed of nine small grids.

Bai Lan held the Rubik's Cube high in her hands and faced Di Yun. "The gameplay of the Rubik's Cube is very simple. After disrupting the order, integrate them back into place to win."

As she began to demonstrate, she quickly twisted the Rubik's Cube in her hand, turning it left and right, and showed the scrambled Rubik's Cube in front of everyone, "This is what it will look like after the scramble."

Then he quickly rotated again, and in just a moment, the Rubik's Cube was restored to its original shape. "That's it, how about it?"

The Rubik's Cube is very simple. As long as you master certain rules, it can be restored to its original shape within a few seconds. However, without a certain foundation, people who don't understand the principles will not be able to solve the problem at all, and will even become more confused and irritated the more they play.

The three old men behind Di Yun touched their beards and laughed, "What do I think they are? Isn't this just playing with blocks?" Their eyes were suddenly full of contempt.

Di Yun also became happy, that's it? "Then let's get started."

On the throne, Emperor Tianxuan vented his anger without saying a word. Hey, forget it, you have already made a bet, just bet generously, and then try to trick him back later, lie, he is very powerful, without him, there is Yun Qin Yunye, these two boys are more capable of deceiving each other than the other.

Thinking about it this way, I feel less distressed.

In the middle of the main hall, Bai Lan and Di Yun exchanged difficult questions. Bai Lan picked up the Sudoku and nodded while looking at it. Her fingers kept making gestures on the paper, and she didn't know when a pen from later generations was added to her fingers.

In just half an hour, Bai Lan had filled in the difficult questions on the paper and happily came to Emperor Tianxuan, "Father, my daughter-in-law has already answered the question."

Emperor Tianxuan's gloomy face suddenly brightened up. He took the paper and looked at it. Horizontally, vertically, or diagonally, they all consisted of numbers from 1 to 9. None of them were repeated, and he suddenly felt enlightened.

"Hahaha, Lan'er is indeed my lucky star."

Looking at Di Yun and the three old men in the middle of the hall, their brows became more and more frowned. The Rubik's Cube was transferred from one person's hand to another, and each time it was in the hands of another person, the person would only shake his head.

The beards of the three elders turned crooked, and Di Yun even broke out in a cold sweat. He was so angry that he wanted to curse: This Rubik's Cube must be poisonous. Turn left or right. No matter how you turn, it feels like you are spinning in circles. You can't turn back to the original position at all. As for the position, either this end is almost there or the other end is blocked.

This thing is not difficult, but it requires patience, calming down and thinking slowly. The more anxious you are, the more you will get stuck, and the more difficult it will be to find out.

Bai Lan has solved their thousand-year mystery, but they are wandering around this thing that created a day. It's really embarrassing.

In the main hall, the only sound that was quiet was the sound of the Rubik's Cube turning. However, the quieter it was, the more tense the atmosphere became.

The four of them, Di Yun, stood in the middle of the hall. After searching for three hours, they still couldn't find a flower. Yun Ye yawned loudly and said, "I'm so sleepy, my wife, please give me a quick blow." Beat the back.”

"Okay." Balan stood behind Yun Ye obediently and began to massage his back.

"Father, when will dinner be served?"

Emperor Tianxuan raised the corners of his mouth, narrowed his eyes, and felt happy.

"Lan'er has worked hard today. Please tell me to go down and serve dinner."

On the side, Prince Repingchuan of Yanshu stepped forward and saluted: "Your Majesty, I just heard from the princess that Ningguo spent ten years making sophisticated weapons. I would like to see whether Ningguo's new weapons are more powerful or my Yanshu's. The archery cannon is powerful."

Although Yanshu is a small country, it has a unique weapon called arrow cannon, which has a strong attack power and a long range, and can fire within a hundred meters without missing a target.

In this era when there were only bows and arrows, Yanshu's archery and cannons were amazing. Because of this, Yanshu has never been in decline. In the past two years, it has conquered several small neighboring countries, and now it has begun to make plans for Ningguo.

Coming to worship today is not only as simple as it seems on the surface, but actually to find out the reality of Ningguo.

If they really competed, Bai Lan had no chance of winning. Emperor Tianxuan remained silent. What Bai Lan just said about making sophisticated weapons within ten years is true. However, no matter how sophisticated they are, they cannot match Yanshu's archery and artillery. The significance of archery and artillery on the battlefield is simply like a devil's existence. Excellent equipment. In front of arrows and artillery, there is no doubt that an egg hits a stone.

Emperor Tianxuan was so anxious that his scalp was numb. How should he divert Re Pingchuan's attention and skip the topic of Bai Lan? He cast a look at Yun Ye asking for help, but met a gesture made by Yun Ye with his fingers: thumb and index finger facing each other, three fingers together. This seemed to be the thing that killed Yun Feipeng that day. What was it called? The gun came.

oh! Yes, why did he forget Bailan and that thing. He had seen that thing called a gun. It was extremely lethal and very fast. It could kill people several meters away in an instant. But he didn't know. How did it compare with the arrow cannon?

Bai Lan looked at Re Pingchuan with great interest, "Anyway, Prince Di Yun is still busy turning over the Rubik's Cube. I am also idle when I am free. I just don't know what kind of comparison you want, Prince?"

When she heard Re Pingchuan talk about arrows and cannons, she felt the fear on Pingnan General Qi Tian's face. Qi Tian is a man who has been on the battlefield for a long time. What is the weapon that even he is afraid of?

She really wanted to see it. Could it be said that this was also thought up by someone from later generations?

Re Pingchuan was full of confidence and laughed out loud. He glanced at Yun Ye and Qi Tian and said, "The power of archery and artillery must have been witnessed by His Highness the Third Highness and General Ping Nan."

Qi Tian nodded, sighed, and said no more. Archery and artillery are like a nightmare. As long as the opponent fires one arrow cannon, it can resist an army of 10,000 people, and the arrow cannon will remain unscathed.

Compared to Qi Tian's dejection, Yun Ye was indifferent, "Yes, I have seen how powerful the arrow cannon is. It is indeed as powerful as a divine weapon. However, it may have been a divine weapon before, but it is not now."

"Oh? Really, it seems that the game is getting more and more interesting." Re Pingchuan laughed.

He was too confident in his own arrows and cannons. He firmly believed that no one could beat their arrows and cannons, not only the Ning Kingdom, but also other countries and the entire continent.

"Your Majesty, let's do this. The competition is divided into three games. The first game is about speed, all fired at the same time. Who can shoot the target first? The second game is about lethality. Who can shoot through more boards? The third game is about range. Let's see. Whoever can shoot the farthest. If I lose, I will give you the recipe for making arrow cannons. If you lose, my request is the same as that of Quanguo, only three of your cities.

One is Quanguo and the other is Yanshu. They want three cities. They must have discussed the situation in advance. Or maybe they have been coveting Ningguo for a long time and are afraid of serious damage if they attack. After all, Ningguo still has a Night King who is in charge. They won't get any benefits from fighting.

The people below dare to be angry but dare not speak out. The reason is very simple. It's not because they don't want to come out to fight, but because they really don't have the strength, especially Qi Tian.
