The grape ditch is about 8 kilometers long from north to south, about 2 kilometers wide from east to west, it is a canyon under the flame mountain, the widest part of the ditch is two kilometers, the narrowest place is about 600 meters, there is the Buyiluk River in the ditch, the main water source is the high mountain snowmelt, because the ditch is rich in wild grapes and gets its name.

In April in the Western Regions, there is a bright scene of spring everywhere, and the wild grapes have drawn thin branches, and the young leaves are decorated with pale yellow leaves; The grass came out with the fragrance of the earth, and the clumps, clusters, and the tender and green flowers also stretched, yawned, and poked out their little heads, as if to tell people: Spring is coming!

The smell of the ditch mixed with sweat, making the laborers less tired, and hundreds of ragged people were building a wavy earthen wall under the hot sun with various tools.

In front of the earthen wall is a ditch about three meters wide, and the soil dug out of the ditch is compacted on the earthen wall, so that the process of carrying the soil from a distance is eliminated.

In the middle of the earthen wall is a city gate with a drawbridge, and the front and back of the gate are urn castles. On either side of the earthen wall are very steep cliffs, on which blockhouses are being built.

This wavy defensive wall was designed by Yun Mo based on the European fortress, which is a kind of ancient fortress, and its essence is to change the fortress from a flat defense to a concave and convex polygonal defense.

This improvement makes it possible to attack any point in the castle exposing the attacker to more than two attack surfaces (usually 2-3) to the defender, and the defender can use crossfire to multi-strike the attacker.

Needless to say, Lingbao's powerful defensive capability has been proven by countless actual battles in the history of later generations. The only regret is that this Ling Fort is all built of mud, and it can't withstand the bombardment of trebuchets at all, and Yun Mo's hands are also short of manpower, so he can only build an earthen wall fifty or sixty centimeters high every day.

The first day of construction went well, and no outsiders came to disturb it, but the second day of construction was not so smooth, and some horse thieves' sentries came from outside the grape ditch, and these sentries were very bold, and they actually rushed to the earthen wall to harass them.

The Han Chinese, who had bought more than 500 people, immediately collapsed, cried and climbed the earthen wall, and then fled deeper into the grape ditch, and the construction work had to be stopped.

Yun Mo had to take fifty female crossbowmen to attack, and there were a few horse thieves who didn't believe in evil before, and they wanted to use their good equestrian skills to trick Yun Mo and their group of foot soldiers.

As a result, these unbelieving horse thieves and sentinels were all shot into hedgehogs without exception, and you must know that the Shenwei crossbow used by female soldiers is a great killer weapon of this era.

An ordinary high-power ancient crossbow, the ancients could only fire three times before they were exhausted, after Yun Mo added two pairs of eccentric wheel pulleys to the crossbow, it saved eight times the effort, the muzzle velocity of the crossbow arrow increased by eight times, and the penetrating power of the crossbow arrow increased by more than two times on horseback.

The Shenwei crossbow used by the female soldiers now, if the directional pulley set is not installed, the average pulling force is 240 catties, and a strong man can pull the string up to three times, and after the directional pulley is installed, it only takes 30 catties to be easily wound.

With this pull, any adult man or woman can easily wind fifty or sixty times. In addition, the Shenwei crossbow is still made according to the principle of Zhuge repeater, and there is an arrow box containing ten crossbow arrows on the crossbow, and the fire rate of the Shenwei crossbow is very fast.

Dozens of horse thief sentry detectives, there is no need for Yun Mo to arrange a three-stage combo, a platoon of female soldiers can easily shoot the horse thief sentry scouts who come to provoke, even if his equestrian skills are extremely clever, his fate will be the same.

As the crisis drew nearer, the construction of the defensive wall could not be delayed for a moment, and the Han Chinese who had escaped were gathered again, with female soldiers in front of them, so that they could participate in the construction work with a little peace of mind.

It's not that these Han people's ideological consciousness is noble, but that this grape ditch is a dead-end canyon from which there is no escape, and they can only come back to participate in the construction of defensive earthen walls in order not to be caught by horse thieves and put in cages.

Fortunately, the food here is good, the corn is enough, and there is broth to drink. In the workshop, there is no overseer whipping, and the construction speed is not slow.

At night, the construction work did not stop, and in the face of the threat of death, people could often burst out with amazing power, and by dawn on the third day, a wavy earthen wall two meters high and two meters wide was stuck like a long snake stuck in the mouth of the grape ditch.

The two-meter earthen wall is not high, but there is a ditch in front of the earthen wall that is two meters deep and two meters wide, and the water of the Builuk River has been channeled into the earthen ditch, thus forming a moat in front of it.

Grape Ditch has now had the prototype of the city, and in the turbulent times of the Western Regions, the Tang people left behind in the Western Regions finally had a small place to live.

When the earthen wall was completed, there was no cheering, as long as there was a thunderous snoring, and the hundreds of people who participated in the construction were all so tired that they lay down under the earthen wall, and then soon fell asleep.

Why did the ancient Chinese build all kinds of city walls? Chinese people are not comfortable if they do not fence themselves, or they have no sense of security, the state is like this, such as the Great Wall, the place is like this, every city has a city wall, the family is still like this, almost every family is like this, the rich build a brick and stone wall, the little people without money, use bamboo to make a fence wall.

This earthen wall has invisibly given everyone here an unprecedented sense of security, and of course it has also become a line of defense in everyone's hearts.

The appearance of a city must always have a name, the name Grape Valley is obviously inappropriate, a loud and domineering name, good is good, it is easy to attract people's attention, and it is easy to attract thieves.

What's the name for it? Isn't the grape ditch fragrant in spring? Then it's called "Qingxiang City", a prosaic city name, elegant but not vulgar.

The river in the grape ditch doesn't need to be called an awkward western domain name, just change the name to the remnant river! This is also a reminder to everyone not to forget the fact that they are remnants of the Tang Dynasty.

Kadier, the owner of Tongtai pawnshop in Jiaohe City, is lame, he has been running a pawnshop in Jiaohe City for nearly ten years, don't look at him usually smiling, it's all superficial, his heart is black.

A good utensil, when it arrives at his pawnshop, it is broken copper and iron, and a top-quality fur coat is eaten by insects and rats, these are the rules of the pawnshop business, and they are nothing.

When Gadir was in good health, he was a small leader of horse thieves, and when he was cut off in a robbery, he was cut off by a leg, and the leader of his gang of horse thieves, Tassie, arranged for him to sell the stolen goods and spy on the situation in Jiaohe City.

When Yun Mo carried a bag of jewelry and jade to the Kadir pawnshop, the old horse thief's eyes were green, so many jewels and jade, how could the horse thief be willing to take out a large sum of money! Isn't the old business of a horse thief just a business without capital?

Therefore, Ge Dier deliberately kept the price of the jewelry and jade pawned by Yun Mo very low, and of course the business could not be done in the end, but he still got up and sent Yun Mo out of the pawnshop with a smile. However, in the eyes of the Kadir, these jewels and jade were already in the pocket of their gang of horse thieves.

Yun Mo A small tail soon appeared behind them, and when Yun Mo left the city, the number of people following gradually increased, everyone was helping the master to find out the news, there was no need to fight each other, so the sentry agents of the horse thieves tolerated each other's existence.
