After returning to the mansion, Yuwen Shudang summoned Yu Wenming to his study and asked kindly, "Ming'er, how did you know the answer?" Those questions were so difficult that even Chang Sun Sheng, a resourceful old minister, couldn't answer them. Who did you learn from? ”

Originally, he thought that someone with a high fortune took a fancy to Yu Wenming and wanted his grandson to be in the limelight, but later he saw that Mubashaf had four questions in a row, and Yu Wenming answered them one by one, so he knew that he had real skills, and it was not someone who taught him in advance, and then asked him to draw a gourd to answer.

Yu Wenming had already thought of a response on the road, and he also knew that his performance was really shocking.

"Grandpa, my grandson has indeed been instructed by a master, it was a wise man who came to the Eastern Capital from the Kingdom of Faranks in the West when he had not yet recognized his ancestors and returned to his ancestors, and he taught his grandson a lot of Western knowledge. In fact, the questions raised by Mubashaf, the envoy of the Great Eclipse, were also often circulated in Western Franco, Byzantine and other countries. That's why Sun Er can answer like a stream...... "Yu Wenming made up lies without changing his face.

And the question of the infinity of prime numbers, which Mubashaf mentioned at the end, was actually the subject of this wise man's lifelong research. Before he died two years ago, he finally figured it out. And at that time, Sun Er happened to be by his side, and listened to him tell the answer, otherwise how could he solve it so quickly! Yu Wenming pretended to be apprehensive and said.

"That's what Grandpa said! No matter how smart you are, you can't be more powerful than so many important ministers in the court! However, for now, when you let the Holy Dragon Yan Dayue enter his sight, if you make a few more great achievements in the future. I think I will be able to go one step further in the DPRK! Yu Wenshu touched his long beard under his chin and said with a smile. Apparently very satisfied with the performance of this grandson.

"Thank you grandpa for the appreciation! Your grandson must work hard and not pay your high hopes! "If you hit the snake with the stick, Yu Wenming will still say it.

"Hmmm! The day after tomorrow, grandpa and your father will go on the expedition! Your master will also accompany you, and this expedition to Tuyuhun will probably take at least half a year. Tomorrow I will let Li Jing come to the mansion to teach you martial arts, you have to learn from him, his sword skills, lance skills, and archery skills are all superb! Yu Wenshu said.

"Grandson must learn from Master and strive to learn all his skills!" Yu Wenming made a grimace at Yu Wenshu, and now he has deeply felt the care and warmth of his elders from Yu Wenshu.

At this moment, the voice of the horse steward suddenly came from outside the door: "Old Master and Little Young Master, the young lady of the eldest grandson family, the eldest grandson Wujian and a big cannibal are visiting. Said to be looking for the little master! ”

"The eldest grandson and the great cannibal?" When Yu Wenming and Yu Wenshu heard this, they were both stunned for a moment.

"Hehe, if I'm not mistaken, during the day in the court, the Great Food Envoy said that if you answer his question, I will give you a fine horse and a black steel knife. However, he couldn't find our house, so he had to beg Changsun Sheng to send someone to accompany him. Yuwen Shu smiled and said: "It's just that I didn't expect that Changsun Sheng would send his daughter out in person, it seems that my Ming'er still has a big face!" ”

After Yu Wenming heard this, he couldn't help but blush, and then bowed to Yu Wenshu and said, "Grandpa, then the grandson will leave first." ”

"Hmmm! Today is the twentieth day of the first lunar month, the last day of the Lantern Festival, and all the lanterns will be put away tomorrow. If you have time, you might as well go to West Street with your eldest grandson to watch the lanterns. Could have come back a little later! Yu Wenshu said seriously.

Yu Wenming naturally heard the meaning of his grandfather's words, and hoped that he would have more contact with his eldest grandson. He had no choice but to give up his hand helplessly, and then turned and left.

When he arrived at the gate of his house, he saw that the person who came was Usa, the retinue of Mubashaf, the great emissary, who brought a tall Arabian war horse, with snow-white fur and an unusually divine horse. At the same time, he also presented two scimitars that were more than three feet long and black and shiny.

"Young Master Yuwen, this war horse is the best horse among the horses we have brought to Dasui this time. It's just a bit wild and untamable. And these two knives are authentic Damascus black steel knives! Absolutely sharpen iron like clay, blow hair and break hair. Far from being comparable to the knife of the Central Plains, please accept it! Nausa said respectfully.

Yu Wenming ordered the two knives to be accepted, and at the same time instructed the horse steward to lead the horse into the horse porch to feed. It's just that the horse was indeed a little unruly, and kicked and injured a few family members who led the horse along the way, and then it was Yu Wenhua and one of his stables who came over to barely pacify it.

"Young Master Yuwen, we may return to Dashi in a few days, Lord Mubashaf dragged me to bring you a word." Usa said solemnly at this time.

"Oh? What words? Just say it! Yu Wenming was also slightly curious.

"He said that the next time he comes to Dasui, it may be three years later, and he said that there may be great changes in the world at that time, and I believe that by then the young eagles have spread their wings and fly high, and you will also be a blockbuster!" Usa is colorful.

"Huh! Thanks to the auspicious words of your family, I hope so! Yu Wenming smiled slightly. But he was secretly frightened in his heart. Three years later, according to the time calculation, it should be the time of Yang Guang's first expedition to Goryeo. And it was that expedition that caused the resentment of the people all over the world, the people in the north were not happy, and thieves were everywhere. Indeed, it can be regarded as a great change in the world. It's just not known how Mubashaf could have expected this.

However, he didn't plan to ask in detail, after all, if people were willing to tell you about this kind of thing, they would say it immediately. If you don't want to tell you, even if you ask, they won't say it.

"Yuwen Gongzi! Then I'll take my leave and go back! Thank you from the bottom of my heart for solving the puzzle of prime infinity! Let us give the king an account! Usa then put his hands on his shoulders, saluted Umun, and then turned to leave.

When Usa walked away, the eldest grandson Wujian Fang stared at Yu Wenming and said with a grateful face: "Young Master Yuwen, thank you so much this time!" If you hadn't been in a hurry and answered Mubashaf's question, I'm afraid my father would have been beheaded! My brother and I will be demoted to slaves......"

Yu Wenming scratched the back of his head, and said with a smile: "Eldest grandson girl, I am actually lucky, I just hit it by mistake......"

He then took out the story of the wise man of Frank that he told Yuwen and told it again to the eldest grandson Wujian.

The eldest grandson Wujian listened very carefully, and after listening, he couldn't help but sigh: "This is really blessed by God!" Let my dad finally save the day! ”

After that, she looked at the lights and noise in the west, and then grinned and said, "Yuwen Gongzi, why don't we go to West Street together to see how the lanterns will be!" ”

"Okay!" Yu Wenming looked at the eldest grandson's innocent smile like a flower, and he was also happy in his heart. After coming to Dasui, he lived in nervous calculations every day, and he never had an easy day.

At this time, night had just fallen, but the eastern capital was crowded with people and brightly lit.

Today is the last day of the Lantern Festival, and after tonight, all the lanterns will be put away. Therefore, in Luoyang City, hundreds of people happily traveled with their families to watch the lanterns.

The South, North, West and East Streets in the Eastern Capital City are already filled with all kinds of lanterns, illuminating the night as if it were day, which is very spectacular.

"Yuwen Gongzi, which street are we going to see the lanterns?" The eldest grandson Wujian held hands with him and asked with a smile.

"Eldest grandson girl, I usually go to East Street a lot, and I almost never go to West Street, so I might as well go to West Street to have a look!" Yu Wenming thought for a moment and then said.

"Good! West Street is the metropolis, where the style and number of lanterns should be the largest! "The eldest grandson Wujian obviously wants to go to West Street as well.
