After going to Guiguan, Liu Yan was no longer in charge of the world, but he was not completely idle, and began to be interested in some things in Lingxi.

In the courtyard of the public house, under several miscellaneous trees, a buttress was set up, and Wei Daotian talked with several wingmen wearing colorful cinnamon cloth, fiddling with a crossbow-like shooting gear.

And Gao Yue sat on the Hu bed and watched.

These wingmen, both men and women, were all sent by Liu Yan to the heralds, and they were sent to Baili New City with people and things.

The barbarians in Lingxi, the Tang people called them "slang bureaucrats", and the same as the party Xiang Luo, the Tang Dynasty set up dozens of detention prefectures in Guiguan, Yongguan and Rongguan, and at the same time with the backing of force, co-opted the upper echelons of the slang bureaucrats to rule the vast area of Lingxi.

After Liu Yan took office, he saw that there were hundreds of bureaucrats working in the Jingluo Mansion in Guizhou, and their status was almost the same as that of slaves, and they had no money for food, and the government only paid them basic rations every month.

After a little questioning of Liu Yan, he understood that the degree of openness in the Lingxi region was very low at this time, even though the imperial court specially issued the policy of "Lingnan rice", that is, requiring each family to pay half of the rent and tax of the people of the Central Plains every year, but the majority of the local lower-class bureaucrats were still poor, coupled with the cruel exploitation of some officials and chiefs, many bureaucrats who could not afford to survive could only be sold into slavery.

In fact, the largest market for bureaucrats and slaves is still on the side of the Tang people, that is, there are many bureaucrats in the emperor's court who act as eunuchs. Therefore, although the Tang government repeatedly issued edicts to ban this slave trade, it had little effect.

Liu Yan then ordered: The bureaucrats have many skills, and if all of them are placed in the Jinglu Mansion as miscellaneous servants, it is not an appropriate move, so he took out the money in the palace to ransom these bureaucrats, and then set up an official village in Guizhou, and directly distributed materials to the bureaucrats to work—weaving and dyeing, manufacturing weapons, processing the metals from Lingnan City, etc., so as to not only save this group of bureaucrats from the predicament, but also give full play to their value and make great profits for the Jingliu Mansion.

Later, Liu Yan thought of the high three drums, so he specially sent ten wingmen to him, and he traveled half the world along the way.

The first skill that the wingman showed to Gao Yue was this "wooden bow".

In fact, the wooden bow is a special product of Lingxi's wooden crossbow, which shoots short arrows.

Before Nawei Daotian was bought by Cui Ning, he had been wandering around Lingxi and Lingdong, understanding the language of the bureaucrats, and after talking, he presented this "slang bureaucratic wooden bow" to Gao Yue for observation.

The Middle River and Xuanshu regions are also known for producing good bows and crossbows, but these crossbows use the traditional system, using silk rope as strings, wood and metal mixed crossbow arms and crossbows, and crossbow teeth made of copper as triggers (crossbow machines).

Such crossbows are expensive and in bad weather, and their shooting effectiveness will be greatly reduced when they are damp.

In Gao Yue's eyes, the slang wooden crossbow held by Wei Daotian, the crossbow arm and crossbow bow are all made of wood, "Master, the crossbow is called 'Biandan', and the crossbow arm is called 'gourd'." ”

Gao Yue took a look, the bow of this wooden crossbow was curved, and it really looked like a flat pole; The crossbow arm is a thick plank, and a hole is carved out to be used as an arrow groove, narrow in front and wide in the back, like a gourd, and a square hole is chiseled out in the back for pressing the string.

And under this wooden crossbow, there is also a wooden handle, which is used for hand holding, which Wei Daotian said is called "dog's foot".

After saying that, Wei Daotian quickly used a hemp rope as a string, and then put a short crossbow arrow into the arrow groove and pulled it back - this crossbow arrow, Gao Yue looked like a modern missile, and there were two fin-like tails behind it, which were used to balance the flight trajectory.

Pulling to the maximum, Wei Daotian stuck the string with a small bone piece, then picked it up, held the dog's foot with one hand to aim, and then pulled the bone piece with the other hand, stabbed it, and the crossbow arrow ejected thirty paces away, nailed sound, and penetrated deeply into the wooden tie on the battlement, only the two tails were still outside.

"Silently." Gao Yue said in admiration.

Then ten men and women, each armed with a wooden crossbow, swished, each shooting the crossbow arrow into the target with unmistakable accuracy.

"Master, the wingmen use these crossbows to hunt on weekdays, and this kind of crossbow will never miss a shot within thirty steps, and it can also hit eight shots out of ten steps fifty steps away."

Hemp rope, bamboo and wood blocks are simply everywhere, and the head of a crossbow arrow needs to be made of iron.

This kind of wooden crossbow is really simple and powerful, and can be used by men, women and children, and is suitable for us to travel in Yuanzhou.

But then, there are more characteristics to introduce about this crossbowman.

I saw two wingmen take out a small clay pot, carefully take out a dagger, scrape some brownish-black slurry in it, and apply it to the head of a crossbow arrow cluster.

"Could it be?" Gao Yue was surprised.

Sure enough, after a lamb was brought out, the man held the wooden crossbow and fluttered lightly, and the crossbow arrow shot straight into the lamb's hind legs.

The lamb bleated in pain, limped and ran, but before he had run three or five steps, he fell to the ground, and after a few convulsions, he died of exhaustion.

"It's a medicine crossbow...... Gao Yue vaguely heard before crossing, in the eighties and nineties of the last century, some Miao compatriots in the mountainous areas still use this kind of crossbow hunting, it is said that once a 150 pounds of wild boar was shot, ran 500 meters and then died, Miao hunters came forward to observe, only to know that the wild boar was raised hoof, just shot in the toe by the medicine crossbow, and then ran away to break the arrow shaft, but still ran after a poison to death.

Before liberation, Miao Village also used this kind of crossbow to repel the invasion of bandits.

"This poison is refined from the underground tubers of Lingxi's specialty plants, and the effect is really terrifying, even wild boars can kill with one blow, and it is not a problem to kill people." Gao Yue secretly said - Liu Yan said in his letter that he had hired some servants to boil such poisons in Jingluo Mansion, and if you want it, I can ask the caravan to transport it.

"Forget it, this poison is concentrated in the cellar of the county government for safekeeping, unless it is absolutely necessary, I don't dare to take it out for the soldiers in the city, this group of irritable brothers and sisters, if they shoot at each other, it will be terrible."

However, this kind of crossbow can still be popularized in large quantities, and Gao Yue ordered the manufacturing technology to be taught to the city, especially in the horse workshop, all the herdsmen and palms must be equipped, and the women in Fanluoli can also have them, which can be used to deal with the wolves that harass the horse workshop every spring and winter, and the effect is very good.

The emperor had ordered a sum of money to be taken out of the Da Ying Treasury to supply the needs of the Four Horse Workshops, and Gaoyue's Baili New City was also distributed, so he set up a special "wolf hunting reward" to reward the men and women of the party who raised horses and guarded horses (as well as cattle and sheep).

If the wingman crossbow was sent by Liu Yan on his own initiative, then the rest of the things were what Gao Yue asked Liu Yan for before.

Now this envoy is in Guiguan, not far from the sea market in Lingnan, and any novelty can be bought from the sea trade.

So this time, when the wingman came, he brought this kind of thing to Baili City:

This thing was bought from Persian merchants, grass and cotton seeds.
