On the second day of the second month of February, the issuance of new coins was a great success, and all 5,000,000 Tongbao and 5,000,000 Tongbao were sold out, of which all the Jinbao and 3,000,000,000 Tongbao were exchanged for merchants, and the remaining 2 million Tongbao were exchanged for ordinary people throughout Liaonan County to promote their popularity.

Since the issuance of the new currency on the second day of February, the exchange ratio of Tongbao and Jinbao has been one price per day, and finally it has been pushed to a very high price before slowly falling.

After Zhuang Shaoyou found out, he smiled, he had to hurry up and get back the gold and copper mines! The copper used in the last coinage was mined in the mountains north of Hongya Town, and Jinbao was minted from 2,500 jin of gold traded from Goguryeo and Baekje, as well as a small amount of gold associated with copper mines.

On the eighth day of the second lunar month, Sunday again organized a fleet to prepare for the first sea trade of the year, and a fleet of ships of unprecedented scale was moored at the pier in the north of the city, two four-masted warships, six four-masted merchant ships, a total of eight four-masted sailing ships, carrying the specialties of the North that had been accumulated in the past year, and headed south.

The purpose of Zhou Tian's voyage was twofold, the first was to enter the Yangtze River waterway to open up new trade routes, recruit craftsmen urgently needed in various industries such as pottery, shipbuilding, and silk spinning in the south of the Yangtze River, and purchase raw materials needed for handicraft production in southern Liaoning locally, as well as local specialties.

The second purpose was to trade with the Ryukyus, and on the way back, he went to the Wa Kingdom to trade with Baekje and Mahan in exchange for gold and silver to be minted.

Throughout February, Liaonan County gradually recovered the prosperity of last year, especially in Beifeng, with the investment of large sums of money, key industries quickly developed, from the steady flow of grain to let the county directly get rid of the poverty line, to solve the problem of food and clothing of the people, have begun to respond to the call of the government, actively participate in various work, coupled with a large number of immigrants continue to transport to Beifeng, the clay pottery of Santai Town, the salt drying of the southwest coast, and the preparation of silkworm raising in the northern mountains are carried out in an orderly manner.

Soon, March has arrived, Liaonan County stopped all non-emergency work, launched the most important spring ploughing this year, most of the county's more than 45,000 people in Liaonan County have been put into spring ploughing, the accumulation of ploughing cattle last year has reached 5,000 heads, plus 1,000 ploughing cattle in Beifeng, a total of 6,000 ploughing cattle have been uniformly deployed by the county.

The new cultivation method of the Mojia family has also begun to popularize in Beifeng, the number of wheat fields in Beifeng reached 23,000 hectares last year, and the number of wheat fields in Beifeng was 2,000 hectares, including the newly reconstructed Hongya Town and Liujia Town, this year on the basis of last year, 15,000 hectares of new fields have been reclaimed, so that the spring wheat planting fields in southern Liaoning County have reached 40,000 hectares! The arable land west of the Shahe River has been fully developed, and it has begun to be gradually developed on the east bank of the Shahe River.

On March 15, the first spring rain fell on the land of eastern Liaoning, and the whole land was full of joy, especially in southern Liaoning, people who had just completed spring ploughing were pleasantly surprised to see this spring rain, and this year will be a bumper year!

On March 17, Xiangping summoned that two days ago, the Wuhuan cavalry began to raid the hinterland of Liaodong again, but this year's scale is not as good as in previous years, Zhuang Shaoyou and Gongsun Du's dividing policy finally worked, and after the Yuwen Ministry and Ke Bineng were both defeated last year, both sides were very restrained this year.

The food, salt, tea and other items traded by the Yuwen Ministry from Zhuang Shaoyou were also resold to some of the tribes of Kebineng, of course, there was a price difference in the middle, but this move still won the favor of the Ministry, and there was no merger this year, and the threat to the west of the Yuwen Ministry disappeared temporarily, so naturally there was more effort to oppress other small tribes nearby.

Several tribes of Wuhuan in Changli, Liaodong are suffering, and they have not been able to bargain for Wuhuan in Liaodong for two consecutive years, and they did not have a good time in winter, and the white disaster in winter is not serious, so the losses of the various departments are not big, and they are not willing to unite and go to Liaodong to rob again, after all, Gongsun Du's power is obvious to all.

In the end, Lord Wuhuan Qiu Liju couldn't control it, so he could only send 20,000 cavalry under his direct command to Liaodong to plunder, and instructed the leader of the team to take safety first!

After Zhuang Shaoyou received the news, he was in a good mood, 20,000 people, and he had to hide when he saw Gongsun Du! Don't worry about it yourself at all! And there is no movement on the Goguryeo side this year, since last year's transaction of the four-masted shipbuilding, Goguryeo has stopped all foreign wars, it is estimated that at home to hold back science and technology, stationed soldiers!

When Zhuang Shaoyou was in a good mood, Sun Qian came and took the initiative to invite Ying to envoy to Goguryeo, strengthen emotional exchanges, strengthen friendship, and jointly maintain long-term and stable good-neighborly and friendly relations! Zhuang Shaoyou immediately agreed, let's go, Sun Gan's foreign affairs office is now the most idle department, and there is only one foreign guest in the county - Gao Yingying, but he has been living in the county government and refuses to move out.

Not long after the spring ploughing, Wu Liang's subordinates came with the news that gold had been found in the deep mountains eighty miles west of Xi'an Ping, and Gongsun Yan was sending people to mine it.

After Zhuang Shaoyou received the news, he immediately asked people to write to Gongsun Du and Gongsun Yan, hoping to participate in the development of the gold mine, on the condition that all the costs required for mining would be paid by southern Liaoning, and the most advanced smelting technology would be provided to improve metallurgical efficiency and quality, and the benefits Zhuang Shaoyou accounted for 40%, Gongsun Du accounted for 60%, and provided the Xi'an Ping garrison Mojia armaments, including 2,000 double-fired individual crossbow machines, with a range of 250 paces and a number of arrows; Two three-masted warships!

Gongsun Du and Gongsun Yan both readily agreed, it is not a big deal for Gongsun Du to let Zhuang Shaoyou take advantage of it, besides, this kid is still filial piety, mining and metallurgy are all inclusive, and he can do it himself, why not?

As for Gongsun Yan, he was still a little reluctant, the gold mine was originally going to open with his uncle, but now that Zhuang Shaoyou wants to go to forty percent, then he can get at most one achievement, but when he saw the armament provided by Zhuang Shaoyou, he suddenly became happy again.

The last time I fought Goguryeo, I saw the sharpness of other people's equipment, and now it's good, 2,000 crossbow machines fired in double succession, which is much more than the single-shot crossbow machine of the official and military system, and it is sent fast and far! And there are two three-masted warships, I also saw them on the ship last time, although they are not as good as the four-masted warships sold to Goguryeo, but they are much stronger than those tattered ones in their own city, and they are ships that can go out to the near sea, and they can go directly from Xi'an to Xiangping!

As for why Zhuang Shaoyou is so generous? That's because those are second-hand items that are obsolete! There are three three-masted warships left, leaving one as a souvenir, and the remaining two for Gongsun Yan, the two thousand crossbows are equipped with Zhang San's infantry battalion, and now Mo Qiao and Mo Tie have finally produced a batch of new infantry crossbows after five months of unremitting efforts.

The new crossbow machine is still operated by a single soldier, this is the principle, the firing range is still two hundred and fifty steps, but it has become four consecutive rounds, the loading speed is only two percent slower than the original, and it is more lightweight, and the weight is reduced by two percent compared with the original, so that the soldier's load is greatly reduced!

And the infantry battalion was also issued with a new type of large weapon, a ballista! The ballista is three feet three inches long before and after, two feet two inches wide on the left and right, and two feet eight inches high, and four wooden wheels are installed under the wooden chassis, which are wrapped with iron sheets, and the undercarriage and the upper part of the crossbow machine can be disassembled and transported. The Ballista can fire eight larger bolts at a single load, with a range of 600 paces! Pierces several people! Three operators are required, and it is loaded once a minute (5min)!

And with the frequent trade with the grassland, the number of war horses exchanged is increasing day by day, now even the infantry battalion can also be equipped with some war horses for pulling grain and grass baggage, improve the speed of marching, this kind of crossbow can be disassembled and mounted on the carriage at ordinary times, assembled before the war for combat, very convenient, and can be pushed to the head of the city and the ship for defense, it can be said that it kills multiple birds with one stone!

The 4,000 horses of the cavalry battalion have all been replaced with new stirrups, and Tai Shici is designing new tactics to maximize the effect of stirrups. The equipment of the cavalry has also been replaced, replacing the original 4,000 sets of damaged official and military standard armor suits, and newly equipped with a new type of chain mail, which is lighter than the original equipment, and has no effect on the various movements of the bow and arrow and the horse, as if it is integrated with the body, and the chain mail has a stronger anti-bow and arrow penetration ability, so that Tai Shici's cavalry battalion with flying shooting as the main method of combat can improve its survivability in long-range strikes.

In addition, the arrows of the cavalry have also been replaced with wolf tooth arrows with stronger penetration ability and more stable flight trajectory, and now the cavalry battalion carries two pots of arrows, one pot of wolf tooth arrows for horizontal penetration, and one pot of ordinary iron-headed arrows for projectile; There was also a large pot of two kinds of arrows hanging from the horse's head, each with a hundred pieces.

In terms of the navy, the original infantry iron armor was canceled, and the Mo family wooden armor that was more conducive to water warfare was adopted, and the original Mo family wooden armor was improved, focusing on improving the protection and flexibility of the upper body, at the same time, the wooden armor can improve the survivability after falling into the water, the only drawback is that it is afraid of fire, but the prevention of fire during water warfare is very sufficient, and the current water division has not been able to fight with Zhuang Shaoyou's water division, so there is no need to worry for the time being.

After Zhuang Shaoyou got the consent of Gongsun Du and Gongsun Yan, he immediately sent Mo Tie to bring people to deal with relevant matters.
