said that she would wait two days to check the secret passage of the White House, but Su Pan'er was always ready to move in her heart, and almost all the books of Qimen Dunjia in her hand were almost ruined.

Finally, the conclusion is drawn.

The tunnel formation should have been improved by the people who built it in the first place, which is why it is so peculiar.

But speculation is speculation after all, and whether it is as she expected, it must be necessary to go to the field to check it out before she can fully understand the situation.

Before they could act, Su Paner received a letter from Lu Muyi.

The letter said that thanks to Su Huarong's help, he was able to get out of prison.

The rice grain has been successfully purchased, and now it has been loaded on the ship, leaving Yongzhou Mansion, and is on the way back.

However, Lu Muyi mentioned another thing in the letter, at present, there is a shortage of silver frost charcoal in Yongzhou Mansion, which is ridiculously expensive. He spent a lot on buying silver frost charcoal.

He intended to buy a large amount of silver frost charcoal and ship it to Kyoto to sell after the grain was transported back to Yongze by ship. In this way, you can make a small profit in the coming bitter cold.

This incident made Su Paner's eyes light up!

Changze County is located in a mountain col, surrounded by high mountains and dense forests, many trees, and extremely low grain production.

Ordinary people will be able to get food and clothing by growing food, but if they pay taxes on food, they can only be satisfied by tightening their belts.

Although the imperial court reduced some of the taxes due to the disaster, if the ordinary people were allowed to replace the grain they had paid with silver frost charcoal, they would surely be willing.

She discussed this matter with Qin Yi, and Qin Yi also felt that Pan'er's method was feasible. Two people make a decision!

Do what you want!

The announcement was distributed the next day.

On the day the announcement was issued, many people used silver frost charcoal instead of grain to pay taxes.

When Su Pan'er saw it, she discussed with Qin Yi again, and simply used silver frost charcoal to pay everything else such as Ding tax, property tax, land tax, etc.

In this way, the enthusiasm of the common people has been greatly strengthened.

For the common people, that barren mountain has always been barren, except for planting trees, there is no food at all.

At present, silver frost charcoal can be used to replace grain, and it is natural to be very happy.

When the silver frost charcoal is collected, the problem comes again!

Changze County is limited by geographical conditions, surrounded by mountains, and only rugged mountain roads lead to the outside of the mountains.

How to transport so much Silver Frost Charcoal out was a big problem that plagued Qin Yi. If you hire manpower and material resources to walk the mountain road, the cost of investment is too high!

If that's the case, when these silver frost charcoals are delivered, they are afraid that they will not be able to earn much silver.

Su Paner stared at the map of Changze County for a long time, and finally set her eyes on a tributary of a county river.

"Look at this tributary."

Su Paner pointed to the small river on the map and outlined a circular circle along the terrain: "How about we take the waterway?" ”

"No."

This time, it was not only Qin Yi, but even Cheng Lao, Qin Hua, Su Hao and others all opposed it.

"Pan'er, you may not have seen this river in person. The river is turbulent, although it does not freeze in winter, but there are dangerous shoals and cliffs along the way, and the drop is very large. Moreover, this silver frost charcoal cannot be damp, and it is simply impossible to take the waterway. Qin Yi explained carefully.

"Who told you that you can only be transported by boat by water?"

Su Pan'er couldn't help laughing, and a flash of wisdom flashed in her eyes: "Qin Yi, do you remember that the last time we went to the mountains to find Brother Lu, we used to walk through this river?" Did we use the river at the time? ”

"Naturally, it's horseback riding, then it's ......"

Qin Yi thought for a while: "You mean using a bamboo raft?" This is not good, the bamboo raft is too easy to get damp when storing silver frost charcoal. Besides, the drop here is too big, and the bamboo raft transportation is too dangerous. ”

"It's the dry season, and it's a good time to take the waterway."

Su Paner looked like she was damp: "As for moisture, as long as you take moisture-proof measures during transportation, it is not difficult to avoid moisture." In addition, you say that the dangerous shoals and cliffs are as long as the dam is lowered in the appropriate place, the bamboo raft is intercepted, and then the logging road is transported to the next section of the river with the help of the terrain, and so on. Not a problem at all. ”

Her words made everyone's eyes shine!

Cheng Lao immediately slapped the board!

"That's a good idea! In this way, it will definitely reduce manpower and material resources, and it can also greatly save costs. It's really worth a try! ”

Even Cheng Lao said yes, and everyone naturally had no objections.

Then they discussed it, implemented the specific matters, and took their own actions!

After everyone left, Qin Yi couldn't help but hold Su Paner's hand and shake it vigorously!

"Pan'er, do you know? All of our farmers in Changze County have paid their taxes on time this year. This was the only time since the founding of the Great Zhou Dynasty that it was so punctual. And even after the natural disaster in Nagasawa County! And all of this thanks to your good strategy! ”

Qin Yi sighed in his heart, how fortunate he was to marry such a good virtuous helper!

"It can help you solve your worries, and it is also for the sake of your wife."

Su Pan'er hurriedly retracted her hand and glared at him coquettishly: "If you really appreciate me so much, hurry up and accompany me to the underground labyrinth." What do you think? ”

The labyrinth in the tunnel seemed to be able to seduce the soul, and she dreamed of going to it, taking a good look and taking a look!

"Haha! Go, my husband will accompany you! ”

Qin Yi laughed and hugged her: "However, we have to wait a little longer." When this side is busy and the silver frost charcoal is shipped out, I will accompany you! ”

Su Pan'er squinted at him.

"Done! You can say it yourself. Anyway, I'm almost six months old right now, so if you don't want me to give birth in the tunnels, remember to go faster. ”

The meaning revealed in the words made Qin Yi's heart sweat wildly, and he seriously thought about the authentic thing.

This little woman has the ability to do what she says, and he doesn't dare to peep at it.

Secretly, he informed Uncle Cheng of the matter again, and asked Uncle Cheng to explore the way first.

Uncle Cheng naturally agreed.

The most fundamental reason why he came here with Qin Yi was for the underground tunnels of the white mansion, and he frequently went in and out of the tunnels to investigate. Prepare for deep tunnels.

Of course, Su Paner didn't know about this.

Recently, her mind has fallen back to earning some pocket money to spend. She never thought that she would have to rely on Qin Yi's meager income to support her! Relying on heaven and earth and relying on parents is not as reliable as yourself!

She bought four shops and merged three farms. She hired a shopkeeper for several shops and took care of them herself.

Let's not talk about whether the shop should make money, at least in her creed, not losing money is the big thing!

And the three farms are managed by people she trusts.

There are three farms and one of the villages has a hot spring underneath, which is specially used to grow some greenhouse vegetables.

For Su Paner, meat can be skipped, and vegetables are indispensable for three meals. She didn't want to nibble on bok choy all winter — oh, now it's called woad.
