"What else can be done?" Empress Eldest Sun said, "Gu Qing, do you think there is any other way than to make peace with the two countries." ”

"Return to the Queen." Gu Qing said loudly, "There are also interests, interests between the two countries!" Queen: Our Central Plains is rich in products, but they are different, such as the Turks, the Turks live by grazing, they can't farm, so in the winter, when the grass withers, they will have no food after eating the cattle and sheep. ”

"For example, in the Western Regions, they lack water......

As soon as Gu Qing said this, Empress Eldest Sun understood, "You go back first." ”

Silence returned to the Lizheng Palace, Li Er walked out of the screen at the rear, and Empress Eldest Sun whispered, "Your Majesty, can this Gu Qing's words be used?" ”

"Yes!" Li Er nodded.

On the way back, the harem scenery is good, and there are many palace maids here who are slender and exquisite.

"Gu Qing!"

Suddenly a shout made Gu Qing stop, and when he looked back, it was Gao Yang, "Princess Gao Yang." ”

"Gu Qing, is this princess good-looking today?" Gao Yang swayed his dress.

Looking at Gao Yang's light blue dress, although it was a little elegant, it had a bit of a fairy spirit, "The princess is very beautiful, like a fairy." ”

Gu Qing did not shy away from what he said, and the palace maid on the side was surprised.

"Say that this princess is a fairy!" Gao Yang smiled and said, "I'm a fairy, aren't you tempted?" Hurry up and be my colt! ”

"That's not going to work!" Gu Qing snorted, "Fairies are good, but sleeping fairies are going to break the rules of heaven." ”

"Humph!" Gao Yang turned his head, "Duplicity, you clearly don't want to be the princess's concubine, what kind of fairy are you talking about!" It's all excuses, excuses! ”

Gu Qing stretched out his hand to the back of Gao Yang's head.

"What are you going to do?" Gao Yang blushed a little at Gu Qing's sudden movements.

Stretching his hand back, Gu Qing had an extra flower in his hand, "Give it to Her Royal Highness the Princess." ”

"Huh?" Gao Yang looked at the flower, and then looked behind him, "Where did the flower come from?" You conjured it up? Immortal law? ”

"It's called magic." Gu Qing took out another penny and put it in the palm of his hand to cover it with his other hand, shook it in front of Gao Yang, and after opening his palm, the penny had already turned into two pennies.

"Huh? It's become two texts, how did you make it up? Gao Yang said again, "Do it again." ”

Gu Qing covered the two pennies with his palm again, shook it again in front of Gao Yang, and opened his palm to already have three pennies.

"It's amazing!" Gao Yang was surprised, and took out a small silver cake, "Quick, change this!" It's going to be rich! ”

Gu Qing: "......"

Is this princess ruined by herself?

"It's magic, it's a trick, it's not made out of thin air." Gu Qing explained.

"It's fun!" Gao Yang said excitedly, "Teach me quickly!" ”

Gu Qing patiently explained the technique to Gao Yang, Gao Yang learned it after demonstrating it once, and he was very happy after playing again and again.

"The last general will have to go to the test, farewell." Gu Qing hurriedly left.

"Gu Qing, you stop!" Gao Yang followed, "This princess doesn't allow you to lose to them, anyway, the sisters in the palace can't marry far away!" ”

"The last will understand." Gu Qing said, "Her Royal Highness the princess, go back quickly, don't worry!" I'm here. ”

Gao Yang stopped and looked at Gu Qing's back, rest assured! With me, this sentence echoed in her heart for a long time, and she looked down at the group on her body again, and said to the palace maid beside her, "Go back and make a few more sets of such dresses for this princess." ”

"Doesn't Her Royal Highness need any other clothes?" The palace maid asked again.

"No, you don't! As long as he likes it. Gao Yang jumped step by step and went back happily.

Gu Qing returned to Taiji Palace again, and Li Tai began to explain the topic, "6 officers of 6 different ranks from 6 different military ranks are selected by 6 different regiments, a total of 36 people, arranged in a square of 6 rows and 6 columns, so that the 6 officers in each row and column happen to be from different legions and have different military ranks, how should this square be arranged?"

As soon as the question came out, there was silence in the Taiji Palace......

Six regiments, six ranks, six officers......

After listening to the question, Cheng Yanjin was full of the number six, so dizzy...... I suddenly want to sleep.

"You may not have heard clearly, but the king is talking on one side." Li Tai repeated the question again.

Still silent......

Gu Qing looked at their expressions, this is a very famous combinatorial mathematical problem, which cannot be solved without a certain formula, not to mention that a thousand years ago, even in later generations, it took people nearly two hundred years to solve this famous mathematical problem and demonstrate the most famous Euler square.

The envoys of the Western Regions gave up.

Nanzhao also gave up.

The Turks also gave up.

Tuyuhun gave up......

Only Songtsen Gampo was still racking his brains to keep writing and drawing, put down the pen and said, "What is the answer!" ”

Li Tai took out a piece of paper, on which some of the three arrangements were written, "In fact, there are many solutions. ”

"Why can't I figure it out?" Songtsen Gampo said.

"Our Zhonglang general said that to calculate this, you need to find a formula first, and you can't arrange it without a formula." Li Tai said.

"Hahahaha!" Songtsen Gampo laughed for a long time and said to Gu Qing, "In this Central Plains, I admire Songtsen Gampo, and you Gu Qing is the only one." ”

"Take!" Gu Qing said.

Songtsen Gampo walked out of the palace and returned to the post house angrily, the envoys of other countries were discussing which princess was the most beautiful, Songtsen Gampo said leisurely, "If you want to say that the monarch of the Tang Dynasty today, the most beloved princess is Princess Gaoyang, and this Princess Gaoyang has not yet married." ”

Gu Qing took advantage of the night to come to the leading guard and found that Di Renjie had already gone back, and he saw Brother Qiang and a few soldiers playing cards, "Brother Qiang, how much have you won?" ”

"Not much!" Brother Qiang said with a grin.

"How much did you lose?" Gu Qing asked a few more soldiers.

The soldiers also waved their hands again and again, and smiled bitterly......

"General Zhonglang, do you want to have two too?" Brother Qiang said, "Anyway, you won't be on duty tonight." ”

"I'm going to rush home and stop playing, you guys have fun." Gu Qing said and waved his hand and left.

When I walked out of Chang'an, I saw Princess Gaoyang.

"Why are you here?" Gu Qing said in surprise.

"I'm going to see the imperial sister, you think I'm waiting for you, stinky beauty!" Gao Yang said.

Gu Qing looked at her, obviously there was a sedan car, and she had to walk.

Fireflies were flying outside the city, and Gao Yang walked beside Gu Qing and asked, "Gu Qing, what color do you like?" ”

"Yellow." Gu Qing said.

"Isn't it blue?" Gao Yang glanced at his group, raised his mouth and said, "Men are really duplicitous!" ”

"You look good in everything, blue and yellow, okay." Gu Qing said lazily.

"Humph!" Gao Yangjiao said angrily, "Perfunctory! Stinky man! ”
