After Li Qing returned to the house, he immediately called his spies.

"Li Shang dares to attack the idea of my Ministry of Industry, then don't blame me for being unkind, whether it is the Ministry of Rites or the Criminal Department, find out their problems for me as soon as possible, and I will impeach them fiercely."

The spies were ordered to retreat.

And just when Li Qing was giving such an order, Li Yu also returned to the house.

Now, Fang Xuanling is in charge of the Ministry of Industry, and he is equivalent to owning the Ministry of Industry, and his father asked him to go to the Ministry of Industry to experience, which seems to be sending him some signal.

The household can be collected, but how to collect it is a big problem.

Li Yu still knows more or less about Lu Tong, the head of the household, he is a particularly fair person, he never favors or favors anyone, and the things he once did in Shuozhou were announced by him in the imperial court.

Judging from these circumstances, Lu Tong may have a good impression of himself, but having a good impression does not mean that he is willing to take refuge in himself.

The most important thing is to start from other aspects of Lutong.

Of course, this kind of thing can't be rushed, Li Yu decided to go to the household department tomorrow to take a look, which can be regarded as a report.

And just when Li Yu was thinking like this, Cui Tong ran over.

"Lord Wang, the Mid-Autumn Festival is the birthday of the saint, have you thought about what gifts to prepare?"

"Father's birthday?" Li Yu was stunned for a moment, and then thought that Li Yuan's birthday was the Mid-Autumn Festival, but after understanding, Li Yu couldn't cry or laugh.

"Cui Tong, is it a little early for you to say this now, it's only early July, almost two months before the Mid-Autumn Festival, what do you say are doing so early?"

Cui Tong said, "Lord, the gift to the saint must be carefully prepared, the slaves and maids feel that there is less in two months, don't you know, the gift is good, the saint is happy, maybe it will be promoted to the prince for you." ”

Prince is generally the same word, such as King Qin, King Yi, they are all one level higher than Li Yu's King Yongde, Cui Tong now always wants Li Yu to be promoted to prince.

Li Yu also wants to be promoted to prince, after all, this means that he is one step closer to the position of prince.

But even so, it was too early to prepare a gift, and besides, he couldn't think of any gifts to give for the time being.

"You don't care about this, this king has his own plans." If you don't know what to give as a gift, it's a big deal to buy it from the mall.

Cui Tong saw that his prince didn't care so much, so he couldn't help but pout, "By the way, the prince, the vassal kings from all over the country will also come, and by the way, there is also Su Fu, the mighty general who guards Qizhou, he will also come back to congratulate the saint on his birthday." ”

Hearing Cui Tong talk about Su Fu, Li Yu's brows suddenly condensed slightly, this Su Fu is the general with the highest prestige in their Tang Kingdom, and he once followed his father to fight in the south and the north, and has made a lot of contributions.

Now they are guarding Qizhou, and Qizhou is adjacent to the Central Plains, that is to say, to prevent the Central Plains countries from making any changes to their Tang Kingdom, it is all up to Su Fu.

And Su Fu is a person with great achievements in war and extremely shrewd, to win him over, but he can't let him have too much power, it is definitely a difficult thing for his father to grasp.

Su Fu entered Beijing, but he was afraid that he didn't know what was going to happen.

Li Yu thought in his heart, he still didn't take it seriously, so Su Fu would come and take care of him.

---------------------

Li Yu didn't have anything to do all afternoon, which made him want to go to the household department more and more.

Early the next morning, Li Yu went directly to the household department.

The household department is in charge of the finances, money and grain of the Tang Kingdom, and it can be said that it is the fattest yamen of the Tang Kingdom.

However, Lu Tong is the secretary of the household department, and it is not easy for the officials here to be greedy for ink.

It can be said that the household department and the military department are the two cleanest places in the Tang Kingdom.

After Li Yu came, Lu Tong and other officials hurriedly greeted him, although he was only here to be a waiter, but in the end, it was the prince, and these people really didn't dare to see him as a waiter.

"Lord Wang."

Li Yu nodded, "You don't have to be like this, this king is here to experience and understand the situation of the household, you can just take this king to see." ”

Everyone looked at each other, and their faces were a little embarrassed.

In fact, they didn't believe in Li Yu's ability, so Li Yu said to look around, maybe he really looked around, maybe his purpose was just to win over Lu Tong.

However, with their understanding of Lu Tong, even if Li Yu makes a lot of efforts, he may not be able to succeed.

"What, this king can't see it?" Seeing that everyone didn't move, Li Yu was faintly angry.

Lu Tong hurriedly stepped forward and said, "I'll take the prince around to see." ”

Li Yu bowed his head, and then followed Lu Tong to see the situation of the household, in the process, Li Yu did not have the slightest intention of wooing Lu Tong, did not show favor to him, and even, when he saw some problems, he would point them out very unceremoniously.

Lu Tong felt a little strange when he saw Li Yu treating him like this, in fact, before Li Yu came, he felt that Li Yu might win him over, after all, he wanted to compete for the position of prince.

But Li Yu not only did not win himself over, but also criticized some of his work, which made him a little puzzled.

To be honest, he was a little uneasy in his heart, especially uneasy.

If Li Yu said it, he would be able to deal with it, but if Li Yu didn't say it, he would have no bottom in his heart.

Li Yu walked out of the warehouse of the household department, there were still a lot of things in the warehouse, some grain, some tributes from all over the country, of course, there were also some money from the household department, these money were very hidden, and there were many organs, even if it was Li Yu, he could only know the location, but he could not walk in.

If you want to enter, you have to have an order from the emperor, that is, a voucher for appropriation, and the voucher has the emperor's seal on it, and then five or six people in charge of the key come in together to be able to take the money.

Li Yu had heard of these before, but he had never gone in, and when he came today, Lu Tong didn't lead him in, because he couldn't stand it alone, and he had to have five or six people's keys before he could get in.

It is right to be cautious in this way, O of the country's treasury.

After looking at the warehouse, Lu Tong led him to the calculation room, which is actually a place to do all kinds of statistics, where some bamboo tubes are written with dense accounts, and many account owners have to calculate one by one, Li Yu took a look at it, and he was a little surprised.

Not to mention that there is no paper, it is very troublesome to engrave on the bamboo tube, and it is also capitalized numbers, which is not convenient for Arabic numerals at all, of course, the most unacceptable thing for Li Yu is that there is no calculation tool abacus, and these bookkeepers calculate one by one.

How long does that have to be calculated?

"In recent years, the territory of the Tang Kingdom has been larger, and there have been more taxes, and these bookkeepers have been much busier, so half of the time of the year is counted here."
