Du Lan saw that the tenth elder brother was obviously angry, but he still smiled calmly, and said: "It's not that the concubine doesn't believe you, but this is Lan Tingxu!" ”

"The first line of books in the world has not appeared since Taizong of the Tang Dynasty. After so many years, it suddenly came into the hands of the master, didn't you doubt the authenticity of this Lan Tingxu? ”

Dulan's words are very reasonable.

Brother Shi's anger gradually dissipated, and he began to think.

More than a thousand years!

Lan Tingxu, who has disappeared for more than a thousand years, has never been revealed in the world, but it has fallen into his own hands, and this matter is indeed worth scrutinizing.

"According to Fujin, if you say so, it's really hard to say whether this Lan Tingxu is true or false!"

Ever since the tenth elder brother got this Lan Pavilion Order, he has been shelving it, and only occasionally takes it out to take a look.

"Fu Jin, then you say, how can you identify the authenticity of this Lan Pavilion Order?"

"Well, it's very simple."

Du Lan smiled slightly, "Can you still find the person who sold you the copybook now?" ”

"Of course you can!"

Ten Elder Brother nodded, "This person, called Zhang Deming, claims to be a descendant of Zhang Khan during the reign of Emperor Wu of the Tang Dynasty. This orchid pavilion preface was handed down by Zhang Cambodia, and has always been passed down as an heirloom of the Zhang family, passed down from generation to generation. ”

"Speaking of which, this person is also proficient in physiognomy and fortune-telling is extremely accurate!"

"According to his own claim, his arithmetic originated from Yuan Tiangang, a generation of masters during the Taizong period."

Speaking of this person, the tenth elder brother is really talking, and he admires this person very much.

But to Dulan's ears, this so-called descendant of Zhang Khan and the descendant of Yuan Tiangang is simply a charlatan. This kind of liar often puts on a tall and mysterious cloak for himself, so that he can be invincible.

"By the way, Fu Jin, you haven't said how to judge the authenticity of this Lan Tingxu!"

Brother Shi, who had been off topic for a while, finally came back to his senses, and the topic returned to the topic.

Du Lan smiled slightly, and said, "The master will go to this person again, and he will say, you plan to give this orchid pavilion preface to the queen mother's grandmother as a birthday gift." Then, all you need to do is send someone to keep an eye on this person's whereabouts! ”

The birthday gift for the Queen Mother is still presented in the name of the original handiwork.

If this Lan Tingxu is fake, then this Zhang Deming will inevitably have to run away.

On the contrary, this person will stay in the capital very calmly.

Brother Ten pondered for a while, and felt that Du Lan's idea was still very reasonable.

Just thinking about it, he felt that it was inappropriate.

"Fujin, now at this moment, it is still early for the birthday of the Queen Mother's grandmother. You're not going to let Ye keep an eye on him like this, are you? ”

"If you are this person, you sell a fake, and you see that the fake may be discovered, will you wait slowly for the matter to be exposed?"

Du Lan glanced at the tenth elder brother.

In other words, she would choose to run away as soon as she knew that the matter was going to be revealed. This kind of thing, naturally, the sooner you run, the safer.

"Makes sense, makes sense!"

"Yes, yes, that's it."

"However, you can't go to him so rashly to talk about this, you have to think about it. Well, it's better to have a chance encounter, and then, have two drinks together, and pretend to be drunk! ”

Brother Ten sat there alone, talking to himself.

Du Lan sat on the side, listening to Brother Shi's self-talk, and couldn't help but have doubts in his heart. Didn't you say that Brother Ten was a straw bale? Her previous observation also came to the conclusion that Brother Ten was stupid.

But now, Du Lan feels as if he has been deceived by the tenth elder brother.

For this calculation of people's scheming, Dulan has to give a thumbs up and give a thumbs up.
