The Han and Yuan Dynasty 1-type artillery guns have a total weight of 750 catties (16 taels of system), equipped with 4 catties and 4 taels of iron bullets, with a caliber of 2 inches and 7 minutes, a body length of 4 feet and 5 inches, a caliber of 16.3 times, a firing range of 350 zhang, and a metric system of 1150 meters to 1200 meters.

This is the cast-iron version of the little Napoleonic gun, the weight of the barrel and gun carriage has been increased by 15%, and the range of the shell, caliber, barrel, and double diameter has been reduced by one-seventh while the shell, caliber, barrel, and double diameter are all the same.

But Kong Lingren was overjoyed, and Liu Xian also solemnly said that it would not be a problem.

The reason why it was named Han Yuan, Liu Xian's public explanation is: Produced in Hanzhong, out of the first year of Tongzhi, it is the Han Yuan. And in his heart he really meant, that is the literal meaning.

Liu Xian cast 12 iron cannons of this kind, each with 200 rounds of iron bullets, and the 20,000 catties of iron sent by Zhang Shoudai were used up. Let Liu Xian, who originally planned to cast a few more big Napoleonic cannons, shout that he is very poor, he really doesn't know that the materials used for two hundred shells are heavier than an iron cannon!

Hanzhong's place can't afford to hurt it, and there is not even iron!

The whole cannon casting process took ten days, and then all the relatives and friends of the artillery and Laochao Shuangxi were brought into Chenggu County, which took four days.

For half a month, Liu Xian was not in the army, but the operation of Liu Xian's army was not affected at all. The recruit battalion recruited more than 700 recruits, and all the pensions and subsidies for the disabled and retired brothers and the brothers who died in battle were all distributed to their families, and the battalion headquarters continued to expand to a complete brigade, and the first and second brigades made up for the shortfalls, and at the same time, the 12 mountain-splitting guns were divided into three parts, and the battalion headquarters and the two brigades each got one of them, and the three units each formed their own artillery squads under the organization of veterans left behind by the artillery team.

Counting the young and strong laborers who earned the income of the baggage battalion, the strength of Liu Xian's army approached the 2,000 mark. Moreover, there was also a coolie battalion under the baggage camp, which had grown to three or four hundred people.

It's November. Duolong'a's army went north to Lu's family, and the Taiping army's movements naturally followed, and part of the troops continued to attack Yunyang, and the main force went out of Hanzhong for the second time under the leadership of the main general Chen Decai, Duanwang Lan Chengchun, Zunwang Lai Wenguang, Qiwang Liang Chengfu, and the main general Ma Ronghe.

Yunyang advanced westward, and the 200,000 Taiping army first captured the old and new cities of Xing'an Mansion (Ankang City), which seemed to be effortless.

Hanzhong was shaken, and the counties that were still in the hands of the Qing court hoarded supplies, money and food, and recruited Ding Yong to defend the city. The Chenggu Volunteer Battalion had recovered to 2,000 men under the operation of these days, and Li Ying threw money and grain, and in just a few days gathered another 500 people.

But whether it is Li Ying or Zhang Shoushan, the head of the warden battalion, they all know that to keep Chenggu County, it is still Liu Xianam's soldiers and horses, and no matter how many people there are in the volunteer battalion, they are just a start.

In the cold winter season, the third heavy snow in Hanzhong is drenched, which can be described as freezing and dripping into ice. But the city and the surrounding four passes, people come and go, exhale into clouds, shouting, trumpets, and completely turn it into a big construction site.

Li Ying asked Hanzhong for food and silver money, and at the same time swiped big-character posters, recruiting young and strong laborers in the county, not fighting but working, strengthening the city wall, repairing the four passes, and taking food and housing. Of course, a large number of young and middle-aged people gathered, and even some old people who were over half a hundred years old had to come in.

The life of the common people is hard, and the winter is a time of slack farming, only consumption is not harvested, and the government manages food and housing and pays wages, which is simply better than working for the landlord in the past years. Giving short-term jobs to the landlord is only for food, not copper.

Therefore, in various towns, the mighty army of peasant workers gathered. The youngest of them was only eleven or twelve years old, with an old beard and white hair, and there were as many as 10,000 people.

After letting Li Ying see it, he returned to the county government and shouted that he was ashamed of the court and failed to educate the people well. As a result, the people of Chenggu County are greedy for small wealth and forget the righteousness, and do not be loyal to the court, but bend their waists for the promotion of rice!

Fan Debang, who was following Li Ying at that time, smiled secretly and disdainfully.

……

"One zhang deep, one zhang deep, and one zhang wide......"

"All groups have paid attention, they have all paid attention, and the completion is guaranteed! If you don't meet the qualifications, the wages will be halved, and if you overtime, the wages will be halved, and whoever wants to get along with the copper and silver, you will fucking cheat and play tricks......"

……

Liu Xian's later 'contractor' skills were used on the current construction site more than 100 years earlier. With the village as a unit, the laborers of the same village or several villages are organized into a group, contracting a certain lot or a certain work, limiting the time, requiring quality, as long as the quality of the post-work inspection is up to standard, a certain amount of wages will be added for each period of time in advance.

This time period may be measured in hours or days; This amount of wages may be in copper or silver. It depends on the size of the work!

This is the best means and method of spurring the people, once implemented, this big construction site around Chenggu County will not be afraid of people being lazy and slippery.

Now it is a cold winter, the ground is frozen as hard as a stone, the progress of the project is slow, if someone wants to steal and play tricks, when more than 100,000 or 200,000 Taiping troops rush over, how can the city be preserved?

With the county seat as the center and the north, south, east and west passes as the barrier, Liu Xian pulled all his family and the dependents of his brothers into Chenggu County, but he didn't want the city to be destroyed, his heart and blood were destroyed, and his relatives were killed. He wants to turn the county seat and the surrounding Siguan into a big meat grinding ground, so that the Taiping army will bleed so much that they dare not face Chenggu again!

"Yuandu. The purpose of digging these ravines outside the city, the official still knows, but what can these half-sloped earth walls do? ”

Chenggu county town on all sides of Liu Xian set three ravines, each width and depth of one meter, so that a large amount of soil will be excavated in the ravines, these soil in addition to the use of piling up the front of the city wall of the blockhouse, another function is to pile up the half-slope mound.

Each mound has a steep slope of more than 70 degrees towards the city, and a straight wall of 90 degrees outward. Li Ying looked very puzzled, useless. The enemy wants to attack the city with wooden planks, and people can hide under the slope.

Liu Xian laughed, "My lord, these shield cars that can block the bandits are enough, they are still length markers, and our army's artillery fire at the head of the city relies on them to guide and shoot." "The iron cannons are all set to shoot Zhuyuan, and Banpo is the mark.

Now Chenggu County, the county seat is surrounded by three ravines and three strong slopes, and two pillboxes are erected in front of each city wall, which are equipped with two mountain splitting cannons and thirty Ding Yong. The bunkers are brick and earth structures, and the walls of the two-foot-thick bunkers [earth and cement cannot be used at all in this weather] confirm their sturdiness, with a three-story high roof, a well on the bottom, which is stocked with grain and firewood, and surrounded by a deep ditch outside. That is, the four passes outside the county were all lost, the three moats and the two chest walls in front of the city gate were lost, as long as Ding Yong in the fort was calm, it was not impossible to carry it for ten days and a half months.

The four passes of the east, west, north and south are the four large pillboxes standing in the four directions of the county seat, where all the excess streets, houses and sheds and trees are dismantled and cut down, and the bricks and stones obtained are strengthened on the spot, and the excess is sent into the city, as are the wood trunks.

Who knows how long the city will be besieged when the Taiping army enters Hanzhong, if the city does not have sufficient reserves of coal and firewood, a month or two later, there will be grain and rice but immature rice, and the end of the county will be just as tragic.

There are only more than 200,000 people in the county, and now only half of the county is filled!
