The pulley block is more troublesome to explain, Xu Ziling thought about it, and didn't know how to explain it, so he could only smile and say: "The name of this thing is called pulley block, and I can't explain the specific principle of it, this is what I saw in Lu Gong's book!" ”

It doesn't matter if the explanation is not good, it's good to be able to talk about it, Xu Ziling is a person who is very good at, he doesn't know if Lu Ban knows this thing, anyway, everyone doesn't know!

"Oh? What book? Can you borrow a little girl to take a look? Apricot asked hurriedly.

Xu Ziling glanced at the apricot, and saw that this little girl was also looking at herself, I don't know if it was intentional or not, and threw a wink at Xu Ziling.

Xu Ziling knew the purpose of this girl, and pretended to sigh and said, "This ...... I'm afraid I don't know, and I don't know where I threw that book into the corner! ”

"Oh!" Apricot was quite disappointed after hearing this, but her eyes didn't stop seducing Xu Ziling, right! It was a seduction, and it was a blatant seduction, Xu Ziling's face was hot for a while, he thought that he was thick enough, it seemed that he still had to learn like Yuan Tiangang, thinking of the old liar, Xu Ziling hurriedly pulled Yuan Tiangang in front of him.

Sure enough, under Yuan Tiangang's hot eyes, Miss Apricot finally turned her head in disgust and stopped looking at Xu Ziling.

"Hehe, Datang is really a strange person! Subordinates admire and admire! Tuyuhun envoy Murong Zun Wang said to Li Shimin with a smile.

Li Shimin looked at everyone's expressions in his eyes, and he already knew in his heart that those countries were sincerely obedient, and those were different, he said with a smile: "Tuyuhun is under the leadership of King Murong, and the army is getting stronger and stronger!" ”

King Tianzhu glanced at the side face of the young monarch of the empire not far away, and his heart was mixed, the meaning of these words was obvious, it was to remind Tuyuhun!

He arched his hand, and then said: "On the occasion of the introduction of today's banquet, the subordinates tasted that His Majesty the Heavenly Khan had a beautiful little princess, so he specially sent two very precious items!" ”

After listening to this, Li Lizhi looked at the Tuyuhun envoy Tianzhu King suspiciously, and her little face was very excited, not excited that the Tianzhu King was going to give him two precious gifts, but because she was excited about Xu Ziling's novelty just now, as if the things Xu Ziling made were made by her!

However, Li Shimin would be mistaken, he saw Li Liqing's excited appearance, and couldn't help but say to the Tianzhu King: "Oh? Huh, what is it? ”

The Tianzhu King's face was full of difficulty, and he said: "It's just that these two things are exactly the same, only one is true, but the subordinates can't tell the difference, I wonder if His Majesty the Heavenly Khan can let people consider one or two?" ”

With that, he opened the box in his arms, and saw two silver-white diamonds the size of a fingernail glittering in the light.

Xu Ziling gasped, it's so beautiful!

Not only was everyone present stunned, but those girls were staring at the diamond in the hands of the Heavenly Pillar King!

Surprised, Li Shimin's face was full of embarrassment, what is this, I'm afraid that no one present knows, let alone distinguish the true from the fake, what is the purpose of this Tuyuhun move? Bullying me, no one in Datang, right?

"The name of this thing is diamond!" Xu Ziling walked out with his hands behind his back and asked with a smile, "Is it right or not?" ”

The Tugu Heavenly Pillar King looked at the monster in front of him with a very strange look! How does this guy know everything? Who the hell is it? No, is it human?

"How do you know?" King Tianzhu said in surprise, this is when he was wandering around in the West Market, he saw a very black man, he has forgotten what the name of the black man is, but these two diamonds were obtained by him at a great price, but the black man is very strange, he said that there is a real and a false, how to tell the difference between him and he doesn't know.

King Tianzhu fell in love with this diamond after just one look, so he didn't ask which one was real and which was fake, anyway, it was all good-looking, so he bought it all back.

"This stuff has roots in Africa...... The people of that country are very dark...... Well, it's not Middle-earth anyway! Xu Ziling looked at everyone's confused eyes, he really couldn't explain, otherwise he would have to talk about the geography of the world, and if he couldn't figure it out, he would have to talk about the origin of mankind!

However, the King of Tianzhu knew that this kid was at least true of one thing, that is, the people there were indeed very dark, could there really be such a civilization on the other side of the ocean?

Xu Ziling has practiced kung fu in the past two years, and thanks to so many girls around him, it seems that he has gained a little from being mixed in the women's world for a long time.

There are even more such as Li Li, with a look of worship in their eyes, and they can't wait to correct Xu Ziling on the spot!

"Xu Shaoqing is really knowledgeable, but I don't know if I can tell the difference, it's not good for the subordinates to send the fake to His Majesty the Heavenly Khan!" The Heavenly Pillar King asked respectfully.

Xu Ziling knew that this guy was deliberate, and he entrusted Datang in advance, so that everyone thought that Datang was omnipotent, but he just came up with such a problem to embarrass Datang, if Li Shimin couldn't solve it, then Datang's influence in the eyes of Fanbang would be greatly reduced, but now he is very respectful in face, this Tianzhu King is very thoughtful!

Xu Ziling smiled faintly and said: "Naturally, there are many ways to distinguish this, I will give you a simple demonstration now!" ”

Hiss...... Everyone couldn't help but gasp when they heard this, there were very few people who could tell the name and origin of this diamond, but Xu Ziling could not only distinguish the authenticity of this thing, but also use many methods!

"This ...... Your Majesty, this kid didn't blow it, did he? Fang Xuanling touched the drops of sweat on his head, and was still bragging to Li Shimin just now, saying that there is no one in the whole country who can distinguish this thing, even if he can't solve it, there is no other.

"It's not like it, look at the way he swears!" Li Shimin whispered, he had already discussed the rhetoric with Fang Xuanling just now, and he was going to prevaricate this problem back, but he wanted both, who knew that he would kill Xu Ziling halfway.

But how did he know?

While the two were muttering, the Japanese envoy Kyoko said: "I have also seen this thing in Japan, and there are very few of them, but I don't know how to distinguish the real from the fake, Xu Shaoqing can really tell it?" ”

Here it is, here it again, this chick is flattering herself again, Xu Ziling hurriedly pulled Yuan Tiangang in front of him.

Over there, Li Zongqing also looked at Xu Ziling in surprise, he had also read the method of moving the pulley he used, and he had read it in a book, but she really didn't know anything about this diamond, why did this kid know so much?

Li Zongqing didn't find out that he was still a little hostile to Xu Ziling, but he didn't know when he only worshipped!
