Wang Haoran knew that this could not be shirked, and it was always a price to ask for special cases from others, so after pondering for a while, he thought of an idea and said: "Your Majesty, why don't you do this, can the younger brothers hold a show during the Lantern Festival and let the children of the royal family participate?" ”

"What show? In this way, can those stubborn children be enlightened? Li Shimin was puzzled, if teaching and educating people were so simple, Datang would have been invincible in the world. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

"Measure how big the moon is and how far away it is from us."

Wang Haoran said plainly, but Li Shimin's eyes widened in surprise: "This ...... Can this be measured? ”

"I can only measure it roughly, but it will also give you a little more insight into the moon."

"How accurate can it be?"

"Within a few hundred kilometers."

"That's a lot! So what's the use of measuring it? Li Shimin was a little disappointed.

"When the measurement is out, Your Majesty will not feel that this error is too big."

"Why is that?"

"The younger brother once made a simple measurement and found that the moon is 3,000 kilometers long."

Li Shimin was very surprised, if it was really so big, then even if the measured results were a few hundred kilometers apart, it would not have much impact. He can also imagine the influence of this show, which can not only open up the children of the royal family, but also have a great impact on the minds of the people of the Tang Dynasty, and actively said: "This method is feasible, what preparations do you need?" If you need manpower, I can send Li Chunfeng to you. This person is proficient in astronomy, arithmetic, and divination, and will definitely be able to help you. ”

Li Chunfeng's name, Wang Haoran must have heard of it, in his later reflections, Li Chunfeng is a capable god, so he doesn't have much good feelings. And if this thing is done, the credit will definitely be not small, and the fat and water will not flow into the fields of outsiders, Wang Haoran will naturally think of his brother first, so he politely refused: "Although this matter is more complicated, the team of the younger brother can still cope with it." ”

Li Shimin quickly guessed Wang Haoran's little abacus, smiled understandingly, and said, "Then it's all up to you." ”

When Wang Haoran returned home, he began to draw the tools needed to measure the size of the moon, and Li Shimin was also very neat, and Wang Haoran received a gun from Li Shimin not long after he returned home. Although Wang Haoran had told the members of the special team about the methods and skills of using guns before, these people had never touched a gun after all, so as soon as the people sent by Li Shimin sent the guns, he immediately arranged for the special team to start shooting training.

Within two days, the envoys of the Japanese kingdom, Inugami Ota shovel and Yakushi Huiri, came to visit. Wang Haoran didn't know what they were coming for, but it was certain that they would have something to ask for. Wang Haoran is not in a hurry to ask, no matter how good his heart is, he can't be too active, right?

After a burst of praise, the envoy of the Japanese State finally explained his intentions: "The little young master is very knowledgeable, especially the miscellaneous rice researched by the little young master, the yield is high, and it is the supreme merit. It's a pity that the Japanese Kingdom is far away in the east of the Bohai Sea and can't enjoy the blessings of the little master, otherwise the people of the Japanese Kingdom will be able to worry about food and clothing. Yesterday, I asked Your Majesty if you can pass on the miscellaneous rice technology to the Wa Kingdom, and Your Majesty's intention is to let me come and ask the little young master what he means. Therefore, I took the liberty to visit today, and asked the little young master to save the people of the Japanese country from fire and water for the sake of the descendants of Yan and Huang. In Xia and the people of the Wa Kingdom will not forget the favor of the Tang Dynasty and the little master! ”

The dog Yutian shovel wanted to kowtow to Wang Haoran as he spoke, but Wang Haoran hurriedly got up to stop him. In Wang Haoran's view, the Japanese people who can admit that they are the descendants of Yan and Huang are good citizens, and replied: "The canine messenger does not need to be polite!" Naturally, I will not sit idly by and watch the affairs of the Japanese country. Not to mention that the Tang Dynasty and the Wa Kingdom were originally of the same root, and among the boys and girls brought by Xu Fu Dongdu back then, there was our Wang family. I don't know if he has left any children and grandchildren, but now the past is far away, and I am afraid that even if he does, he will not be able to find it. ”

"Then I'll thank the little master first." The envoy of the Wa Kingdom was overjoyed in his heart, and said: "I don't know that during the Qin Dynasty, who in the Wang family of the little young master crossed to the Wa Kingdom?" If you have a name, you can also check it after returning home. ”

In fact, Wang Haoran didn't even know if there was a person surnamed Wang who followed Xu Fu Dongdu for hundreds of years, and this nonsense was just trying to have more to do with the Wa Kingdom, maybe it might be used in the future, so he continued to make it up: "I don't know what his name is, after all, it's a long time ago, and now if you want to find his descendants, I'm afraid it's impossible." ”

"That's really hard to find, but you can also try, anyway, it's not troublesome, the little young master is the pride of the sky, what other information do you know about the Wang family? After I go back next time, I will send someone to investigate, maybe I can really find it! Inugami Ota Shovel said positively, thinking that even if he didn't find it in the future, wouldn't it be okay to arrange one by himself? It is possible that the young master will take care of his family's life in the Japanese country, and it is possible to take more care of the Japanese country.

The intentions of the two sides coincided, and Wang Haoran did not refuse, and said politely: "Then it will trouble the dog messenger." ”

"It's just a little thing, little master doesn't have to worry about it." Inougami Yutian spade was a little embarrassed and said, "Forgive me for being presumptuous, under the surname Inugami Yu, the name Tian spade." However, it is nothing for the little young master to call him like this, it is just a title. ”

"Oooh...... That's me abrupt, and I hope the dog will forgive me. ”

"It doesn't matter, the cultures of the two places are quite different, and it's normal for this to happen. In fact, I have always wanted to take the name of Datang in Xia, I wonder if the little master can help me take one? "Inougami Yutian spade also tried his best to have a relationship with Wang Haoran.

"Well...... this" Wang Haoran thought for a moment before replying, "If you interact with Datang, you should indeed take another name, it's not good to have a dog in your name, because in the eyes of Datang people, dogs are despicable existences." Why don't you ask Your Majesty to give you a name? In this way, it can also reflect the friendship between the two places."

"I see, no wonder when the name was reported when the Tang Dynasty was first opened, other people couldn't help laughing and whispering! However, will His Majesty agree to give His Majesty a name? ”

"Definitely, in fact, Your Majesty also thinks that Datang and Wa are of the same root, otherwise Your Majesty would not agree to let you send students over to learn the culture and technology of Datang." Wang Haoran said so, but he knew in his heart that Li Shimin could basically do things that could make Li Shimin appear lofty and not vulgar.

As Wang Haoran expected, within a few days, Inoushang Yutian spade and pharmacist Huiri came to visit again, Li Shimin has given names to these two envoys of the Japanese Kingdom, Inoushang Yutian Shovel named Xu Yuanbang, and Pharmacist Huiri named Xu Jinjiao, which has the implication of friendship between the two places is self-evident, and these two envoys of the Japanese Kingdom are naturally very happy. Although Wang Haoran didn't contribute much to this matter, how could these two people let go of such a good opportunity to make friends with Wang Haoran? This time, they came to the door to invite Wang Haoran to the restaurant to celebrate and express their gratitude.
