In the rain, Gao Yue looked at Gailong Mountain at the end of the Han River, and also pondered the problem of Liu De's room.

After a long time, he said to Liu Demur: "Fang Zhai, go back to the house immediately to discuss this matter carefully." ”

At nightfall, in the dark sky, the rain was still falling, and in the official residence of the military government, Gao Yue and Liu De were holding candles, studying the construction of the horse boat yard and the lake weir in front of a pile of drawings and files, as well as the camp fields of the entire Xingyuan Mansion.

Yu Xiao, Ah Ni, and even Zhi Hui and Ah Cuo have all slept.

Now, for the boat yard of the Dazhu River, its regulation has long been familiar in Gao Yue's heart.

Gao Yue pointed to the map of Xingyuan Mansion and told Liu Demur:

"The city wall of the military palace is close to the Han River to the south, and I am going to move the city wall near the water back one and a half miles, and then expand the sub-city along the southwest of the city, so that it is adjacent to the boat yard and lake weir of the Dazhu River, and then build a big watchtower at the head of the sub-city."

Then Gao Yue explained to Liu Demuro that when he visited the city before, he noticed that the city wall near the Han River had many traces of repair after collapse, and knew that whenever the Han River overflowed, it would infiltrate and wash away the Xingyuan Mansion, which was the original south wall of Nanzheng City.

Therefore, Gao Yue plans to move the southern city wall back to avoid the impact of the river, and there is also more space to form a few more wharves along the Han River to increase the volume of freight.

As for the sub-city in the southwest, it is to protect the farmland of the boat yard and the artificial lake weir, and the second is to consolidate the needs of the city defense.

Gao Yue thought of the name of the watchtower in the sub-city, "Tianhan Tower".

Tianhan is the source name of Hanzhong, and it is also the name that Xiao He once said to Liu Bang, the ancestor of the Han Dynasty, and it is the predecessor of the Han Dynasty.

And the lake weir overlooking Tianhan Tower, Gao Yue also thought of the name, "Pingcai Lake".

That's right, he just wants to rely on Xingyuan Mansion, and after a little improvement, join forces with Wei Gao, Jia Tan, and Fang Zhen in the Central Plains of the Imperial Court to annihilate Taping Huaixi Town.

Then talking about the camp of the entire Xingyuan Mansion, Liu Demuro pointed to the drawings and said:

In the whole Xingyuan Mansion and Yangzhou, the farming conditions are much stronger than Jingyuan. Xingyuan itself has several weirs in Lianshui, Mianxian County in the west of Fuxi, there is Huangshatun, which is the camp of Zhuge Wuhou in the past; The Chenggu in the east of Fudong has a river with a river, which can not only be used for irrigation, but also can be used to transport timber for forging. Yangzhou also has overflow and fushui, and is a small grain producing area.

"In that case, it is not a problem for Xingyuan Mansion to supply 50,000 troops, but why is there so little hukou and so poor taxation?" Gao Yue frowned.

Liu Deshu patted the dossier and explained that Xingyuan was synonymous with prosperity in the Qin and Han dynasties, and it was almost equal to Shu, and it was all Tianfu. But after I arrived in the Tang Dynasty, I lagged behind, and when Jia Gong was the envoy of Liangzhou, he was busy dealing with Liang Chongyi and Li Xilie, and he couldn't take care of the people's livelihood.

In addition, the weirs are in disrepair, the canals are blocked, the people are unable to organize, and the government has no time to take care of it.

Gao Yue agreed, saying that Brother Fangzhai's official training is becoming more and more proficient, and the affairs of Yuanzhou and Xingyuan Mansion are relying on you!

Before Liu Deshu was modest, Gao Yue instantly next topic, most of the county water conservancy that Fang Zhai just said was densely occupied by civil fields and vocational fields.

Liu Demuro sighed slightly, and said that I had read the story of Xingyuan Mansion, Baocheng County in the north of the house, there was a mountain and river weir built by Han Xiaohe, so that it could be tuntian until the Chiya Pass, Zhuge Wuhou Northern Expedition, the general Zhao Yun and the supervisor Deng Zhi, a battle of the Red Cliff Pass, a supervision camp under the Red Cliff, and every time they met, they had to climb the peak.

But now because the mountains and rivers are deserted, that area is all "stained land", and the people will not go there to grow crops.

Stained land, that is, saline-alkali land.

It seems that if you want to start camping, you can't just open up wasteland everywhere like in the past when Baili City was in the past, and you can only make an idea on the stained land from Shanhe Weir to Chiyaguan.

"For this question, I will write a special letter to consult Master Mingxuan immediately." Gao Yue thought to himself, there is still an Alanta Temple in Baili City to support him!

The top priority is still the shipyard.

With a route and a ship, naturally there is everything.

Of course, the topic still returns to what Liu De said in the afternoon, the issue of hard labor.

Gao Yue understood that taxation and labor were the two heaviest burdens on the shoulders of the people in feudal society, but the difference between the two was that taxation made the people poor, while labor directly caused the people to die.

Imagine that you are a peasant in a feudal society, you can pay taxes while farming, you can still have a surplus when the year is good and the politics are clear, and when the situation is serious, it is a big deal to abandon the wasteland and run away, to be a wanderer, and you can't die until you are in a desperate situation; But labor is different, there is a fixed time every year, you have to build walls for the government or the palace for free, repair the palace room, send military rations, repair the embankment, once the conditions are worse, it will really cost a lot of dead people.

Later rulers also came up with a compromise approach, at least in the Tang Dynasty, which was nothing more than two ways:

The accounts are divided according to assets, the rich lose money and serve on behalf of the poor, and the poor get paid for the service;

The use of the army to serve in labor was more common in the middle and late Tang Dynasty, such as Gao Yue's construction of Baili City, which used soldiers, and later came to the Great Song Dynasty, this situation was even more common.

But now, the Baicao Army shoulders the responsibility of protecting Shangjin Road and Hanshui, and the state soldiers of the three states are to unite their children, and to protect the cities and courtyards of each state.

However, Gao Yue must be cautious about the use of labor, after all, Xingyuan Mansion is a young "Datang Municipality", if he does not handle it properly, there will be a danger of boiling public resentment.

After all, in this era of backward productive forces, it is really not too easy to die, and the social structure should not be too fragile.

"The households of Xingyuan Mansion are divided into nine classes, the first six classes are rice, silk, and money instead of labor, and the last three classes are exempted from two taxes, and labor is paid, and the labor itself can be paid." Gao Yue said, and then he thought, "Then on the side of the Dazhu River, food sheds and lodging sheds will be set up to ensure the food, clothing and accommodation of the people." When the busy farming season is over, the project starts immediately. ”

That night, after studying for a long time, Gao Yue finally went to bed.

When they opened the door, Yun Shao and Jing'er had already fallen asleep for a long time......

As a result, the next day, as soon as Gao Yue sat in the office, a post letter from Xiangyang arrived, and Gao Yue hurriedly opened it and read it.

Inside, Jia Tan said that the situation in Shangjin Road has changed!

What the!

When reading further, it turned out that Han Rong's ship had now passed through Ezhou and arrived in Xiangyang City, but Han Rong was also more cautious, and he asked the wingmen who accompanied the ship to send several light boats up the Han River after arriving in Xiangyang City, and saw how the "road conditions" of Shangjin Road were.

As a result, there was no threat of mountain sheds or river thieves for the time being, but there were dangerous shoals blocking the countryside from Shangjin to Yun, and a large fleet of ships passed through, and I was afraid that a considerable part of it would capsize (when Jia Tan left before, there were not many boats, and most of the teams under his command took the land route), Han Yun's escort officer did not dare to take the risk, and asked Jia Tan and Gao Yue to solve it as soon as possible and open up the land route.

Otherwise, Han Rong could only transport the ship and grain to Xiangyang City.
