He thinks that he is also a bit of a city government, but he is still seen through by Lu Wan at a glance.

"Speaking of which, their way of hiding the silver is so good that I almost won't find out."

"Oh?"

"They melted the silver and poured it into the bed."

This time, Lu Juan also raised his eyebrows slightly, this move is really powerful.

"It's a shame that they came up with such a hidden way to save money." Lu Wan shook his head.

"So it seems that the source of this money is indeed unknown."

A hint of thought flashed in Lu Wan's eyes, if it was from a regular way, why did it take so much trouble to melt it, unless the silver was engraved with the mark of the official silver of the country.

"Well, I also took the opportunity to go to two rooms where no one was there, and found that the beds were also moved." Li Yuan said in a deep voice.

How much silver does it take to cast a bed made of silver, let alone so many beds, you can see that the amount behind it must be staggering.

"But there's one more crucial thing you can't see." Li Yuan frowned.

"What?"

"When I went, Manniang was looking at something that looked like a ledger." Li Yuan's voice was very low.

The road is clear.

If you can get this ledger, you can know what the exact amount is.

"It's a pity that this Manniang is very vigilant, someone knocked on the door in the middle, she locked the ledger, I went to see, it's not an ordinary lock."

Lu Wan nodded, such a large amount of money, there must be a record, this account book must also be very important, it is conceivable that Manniang is cautious.

"Do you remember what the lock looks like?"

"Yes." Li Yuan nodded.

"Go back and draw it for me, maybe there's a way." Lu Wan said in a deep voice.

"Okay."

However, Lu Juan suddenly thought that the problem was that this Flying Dance would only be performed once in ten days, and he might not have time to come back, so he had to find another way.

Back at the inn, Li Yuan drew the structure of the lock.

"It really doesn't look like a common lock on the market." Lu Wan frowned slightly.

Just as the stalemate was at an impasse, there was a knock on the door.

"Who?" Lu Wan put away the drawings and asked vigilantly.

"Yu Gongzi, it's me, I bought glutinous cotton cakes, do you want to eat them!" It is the sound of forsythia.

Lu Wan breathed a sigh of relief.

"Come in."

Forsythia held the oil paper bag in his hand, pushed the door in, and saw that Li Yuan was also there, his steps were stunned, he was a little dumbfounded, and he still had half a cake in his mouth, and he didn't know whether to enter or not for a while.

"Why are you stupid, come in and close the door." Li Yuan said lightly.

"Oooh." Forsythia rushed in and closed the door.

Lu Wan will suddenly unfold, looking at the lock on the map with a little headache.

Forsythia slowly moved to Li Yuan's side.

"Childe, it's so late, why are you still in Jade Child's room?" She asked cautiously, just that it would be better to ignore her gossip eyes.

Li Yuan's expression was a little unnatural when she asked.

"You're still talking about us, why did you come back so late!" Li Yuan gave her a blank look.

"I...... You've gone shopping for a day, and you've left me alone in this inn, and I'm hungry!" Forsythia was somewhat aggrieved.

Lu Wan took her cake, his eyes still looking at the paper in his hand.

"Jade Gongzi, what are you looking at?" Forsythia leaned over with some curiosity.

Seeing the drawings in Lu Xuan's hand, he said.

"This lock is so familiar!"
