After Ren Qing finished speaking, he handed the abacus one more point, the corners of Lan Tian's mouth raised slightly, and he didn't shirk at the moment, and reached out to take the abacus.

Ren Qing smiled and wanted to leave, but Lan Tiantian shouted, "Miss Ren wait a minute." ”

Ren Qing turned her head, but saw Lan Tiantian pick up the small abacus and touch it gently, and then she didn't know where she touched the machine and pulled it gently, and saw that she got a big key made of gold and pulled it out.

That key was extremely exquisite, and the tooth patterns on it were very complicated, just at a glance, Lan Tiantian could already see that the key was an extremely special existence, no wonder Gu Qingfeng could be so reckless at that time.

Lan took the key in his hand, and then pulled the trigger and got the abacus back.

Ren Qing was stunned when she saw her movements, she just smiled slightly and said, "Although the Lan Mansion is not as big as the Gu Mansion's business, it is still not worth this gold. ”

Ren Qing smiled when she heard this: "Taifu Mansion can also take it." ”

The corners of Lan Tian's mouth raised slightly, she glanced at Ren Qing and said with a smile: "After you go back, the people of the Gu Mansion will definitely go to the Taifu Mansion to ask for this abacus, you will return this abacus to them, and what I owe you will naturally make up for it." ”

Ren Qing nodded slightly, but couldn't help asking, "I saw that you just roughly flipped through the account book today, did you really calculate those numbers in such a short period of time?" ”

This is her biggest question today, and it is also what she is most curious about.

Lan Tiantian smiled slightly: "I just looked at the pages of that account book to see if Gu Qingfeng was doing anything on it, and when I looked at it, I also looked at those numbers, that is, where am I so powerful that I can calculate the numbers in such a short time?" ”

"But didn't you do it word for word? At that time, you didn't see Gu Qingfeng's number, and you didn't see the number I calculated, how can you know that number? Ren Qing's eyes were full of puzzlement.

"Of course you told me." Lan said with a smile.

"I told you?" Ren Qing's eyes were full of puzzlement and said, "But before I said those numbers, you had already calculated them, how could I tell you?" ”

"It's the voice you're going to dish." Lan Tian smiled slightly.

"I'm going to make a sound?" There was more confusion in Ren Qing's eyes.

Lan Tiantian said softly: "Exactly, I have been taken by my father to learn the plan since I was a child, but I haven't liked the plan plate too much since I was a child, and my sister Xingxin likes these very much, so most of the accounts that my father asked me to calculate, most of them were calculated by Xingxin for me, once my father found out that I was lazy, and taught me a good lesson, and then let me plan well." It's just that I really don't have much interest in that thing, so I've been thinking of a way to be lazy without being discovered by my father. Later, I found that the sound of each abacus bead pulling is different, and the sound of going up and down is also different. Over time, I developed the practice of listening to the sound of the beads with my ears, and then listening to the final result from the sound. ”

Ren Qing's eyes widened, she really didn't expect that there was such a way to be lazy in the world, where is this method of laziness, it is clear that only extremely smart people can learn, and it requires an extremely meticulous heart.
