Silla Kim Seung-man returned to China with a full shock, and then advocated that a large number of weapons and equipment were traded in Liaodong.

She was stimulated, Mingguang armor, heavy infantry, this hit her deeply, such a set of equipment, as far as the eye can see, there are not many in the entire Silla, but Zou Yu took it out as a guard. According to her thoughts, there must be many more that she has not seen.

After returning to China, he persuaded his cousin, Queen Jindeman of Silla, to purchase weapons from the Central Plains and strengthen himself. Considering that Silla was an enemy on both sides, and that Kim Yushin also agreed, Silla exchanged grain, cloth, gold, silver, and jewelry for 50,000 swords, guns, and 10,000 leather armor.

On the side of Goguryeo, he also made a lot of money, not only replacing the steel knife promised in advance, but also leather armor and ordinary knives and guns. Although there will be a war with Goguryeo sooner or later, Zou Yu is not worried about this, what he wants most now is to delay time, as long as it develops for a few years, he is confident that he will deal with any enemy.

When the mutual market opened, Zhong Zijin was the first to start, and exchanged a lot of silk, tea, and porcelain from the Central Plains, and transported them back to change hands.

With some small profits, it can attract the Goguryeo family to make a move, so naturally it is impossible to ask for it, especially porcelain, just change it, even if the price is a little lower, it doesn't matter.

After this transaction, the four counties of Beisha have enough food and materials to recruit people and carry out some engineering development in the four counties, without the support of Liaodong and other places.

Although the silk of the Central Plains is very valuable, in Zou Yu's opinion, it is not as useful as ordinary cloth, at least this year it can meet the needs of the rule.

The largest output of cloth must be Jiangnan and Shuzhong, which are currently in turmoil, and the production is already small, plus the distance is far away, and it can be transported to the north, the quantity is not much, and the price is not cheap, it is of course a good thing to be able to add from Goguryeo and Silla.

The whole force is developing in full swing, the days are rushing, and the people are also very energetic, burning bricks, tiles, and building new houses, because it is to improve their own residences, and no one is lazy without government supervision.

Although there is no cement, there is no problem with the use of lime and clay to build a small building with one or two floors, and there is another advantage of adding lime to the wall, that is, there are few insects.

In these years, in the summer of each year, bricks and tiles began to be made to dry, fired in autumn and winter, and then built houses, this law was basically uninterrupted under the rule of Zou Yu.

From Fuyu City to Liaodong City, most of the houses have been rebuilt, and I believe that in a few years, small green tile houses will be popularized. Of course, there are no prefabricated panels, and the attic is made of wooden boards.

Speaking of insects, this is Zou Yu's most annoying, especially mosquitoes, thanks to a good air environment, the mosquitoes are simply as many as cow hair, all summer, during the day is a small mosquito the size of sesame, as soon as the long-legged mosquito appears in the evening, it is really dragonflies and mosquitoes dancing together, dense, flying around, you can hear the buzzing sound at any time.

Many people, in the evening, would make a fire with dry grass, and then put damp branches on it, and wait until the smoke rose and drove the smoke closer to the house.

Generally, there are mint leaves, camphor branches, pitcher plants and other plants that can repel mosquitoes. These plants, in the people's homes, every household has some, generally hung on the wall, on both sides of the door, under the window.

Because of these plants, the smell they emit, is not liked by mosquitoes, and there are snakes and rats, you must know that in this era, there are not a few people who are bitten to death by snakes every year, which is why the Dragon Boat Festival, one of the reasons for drinking realgar wine.

Realgar wine can repel insects and kill parasites in the body, and the common people don't know it, so they mistakenly think that realgar wine can detoxify. Of course, it is more in front of the house and behind the house, burying some realgar.

Sprinkle lime on the foundation, realgar, the same reason, but for a long time, it will definitely have no effect, so if there is a condition, it must be reburied a little bit every year. To put it simply, it is the life experience of working people summed up over thousands of years.

Zou Yu thought of mosquito coils and toilet water, mosquito coils are easier to do, Zou Yu was a child, the old people in the family made incense to worship the Lord, he had seen it, and he only needed to replace it with mosquito repellent plants.

He also knows a lot of mosquito-repellent plants, the most, the best to collect is, of course, wormwood, camphor trees, orange peels, millet flowers and so on.

Of course, these can only repel mosquitoes, to kill mosquitoes, or realgar, but realgar is highly toxic, and the amount must be mastered.

Let people pick wormwood, cut camphor trees, after drying, grind into fine powder, add a little realgar, and then use rosin as a binder, after boiling, use a thin bamboo skewer, evenly wrap a layer, and a mosquito coil is done.

In order to smell better, Zou Yu deliberately added mint, which he used at home, and also added sandalwood, orange peel, etc., to form a mint flavor, sandalwood fragrance, orange flavor, and osmanthus flavor.

After making it, the effect is very good, a long mosquito coil can burn for more than an hour, to ensure that there are no mosquitoes for most of the night, if you sleep a little later, one can survive the night.

Making mosquito coils, of course, is not only for daily use, but also for garrison and marching battles.

The garrison border pass, originally a remote area, can not find so many mosquito repellent materials, and when the army is marching, it is in the wild, the army is stationed, mosquitoes are the most annoying point, many times, people can not sleep.

Zou Yu also knows that mosquitoes can transmit diseases, and mosquito repellent can also reduce the chance of soldiers getting sick, so why not do it.

In general, the logistics of the march take away the realgar that repels mosquitoes and poisonous snakes, but after all, it is a minority, and it can be used by some of the main forces, which is already very good, and most of the time, only generals are eligible to enjoy it.

Mosquito coils are different, easy to carry, simple to make, it can be said that the cost is very low, and it can be carried in large quantities.

Therefore, Zou Yu deliberately made two kinds of mosquito coils, military and civilian, and the civilian ones are all kinds of fragrances; As for the military, not only did the realgar be aggravated, but also mint and honeysuckle, both of which must also be added.

Peppermint refreshes the mind, honeysuckle prevents colds and miasma, and the main material wormwood, which itself has the effect of guarding the right and keeping evil from evil, which can reduce the probability of soldiers getting sick and reduce non-combat losses.

As soon as anything new appears, the first consideration is to apply it to the army, as soon as the mosquito coil is successfully produced, it will immediately make military supplies on a large scale, and once it is launched, it has received praise from the soldiers, especially knowing that this is their prime minister, and personally invented something for them, which made them more moved, Zou Yu's prestige, in the soldiers and soldiers rose to a higher level, and the first to follow, almost all became diehards.
