Yang Yuanpu took Shen Yang, Zheng Hui, and Zhang Ping to look at the Zhuang Tian of Yongchun Palace, and still wanted to reclaim the fields north of Henghe Port.

However, don't talk about Shen Yang, Zheng Hui, who was transferred from Huangzhou Bingcao to the county palace to serve as a military advisor, is also good at learning from the world, and he is an expert in reclamation and hoarding, and he doesn't need Han Qian's beak.

In addition, the selection of the elite guards of the tent is also in charge of Guo Liang, the capital of the Left Guardian Army and the pawn of the tent, and there is no need for Han Qian to point fingers.

The hunting garden on the north side of Yokogawa Port is five miles from north to south and ten miles from east to west, and it used to be the exclusive hunting ground of Emperor Tianyou.

Han Qian, Gao Chengyuan, Guo Liang and others took more than 100 guards and accompanied the three princes in the hunting garden for a long time, in addition to hunting eight fat elk, they also hunted two big wild boars weighing four or five hundred pounds.

As dusk approached, the jubilant cavalry hunched their prey and returned to the Yongchun Palace Manor along the east bank of the Qiupu River.

"That's the grange that my mother gave to Master Han?" Yang Yuanpu stopped on the east bank of the Qiupu River, and saw a three-masted ship moored in the pond on the inside of Yandang Rock, and the parapet wall of the courtyard on the west side of the pond had been built to the chest at this time, and in addition, there was a column of thick black smoke rising in the courtyard, and he waved his whip and asked Han Qian, "Where the smoke rises into the air, is Master Han secretly building some powerful weapons?" ”

Zheng Hui, Shen Yang, Wang Lin and others looked at Han Qian hesitantly, but they didn't expect that it would only be seven or eight days since he took over Yandang Isotian, and he would start construction so quickly.

After Zuo Si's duties were clarified, the Qiuhu Mountain Courtyard and the craftsman workshop were all classified as the properties of the county king's mansion, and Zheng Hui, Wang Lin and others were able to go in to see the details.

Only in this way did they more or less realize in their hearts that when Han Qian instigated the three princes to sit in Xichuan, he may not have completely risked the lives of the three princes to fight for miraculous feats.

It can be said that the Autumn Lake Mountain Annexes have formed a relatively complete system.

In the back mountain more than ten miles deep to build a stone weir, in addition to barricade the stream into a lake, in order to irrigate two or three thousand acres of mountain fields, but also the main thing is to form a stable water flow, so that along the river distribution of large crushed coal water mill, water mill and even iron-making furnace water discharge, can get a stable flow of water impact, which also ensures that the coal yard, brick kiln, lime kiln, mill can be a stable supply of coal cake, green bricks, lime, mill, labor province, the profit generated, has initially guaranteed the Linjiang money shop up to 15 million money per year.

This also means that as long as the 30 million yuan of financing is paid off in advance, the Qiuhu Mountain Villa will be able to provide a harvest of up to 145 million yuan per year, which is almost equivalent to the land rent harvest of nearly 20,000 acres of fertile land.

This does not include the mess that the Han family father and son tossed in Xuzhou and the Xuzhou Boat Gang.

Even if the father and son of the Han family took advantage of the convenience of the three princes and the Dragon Bird Army, Zheng Hui still sighed to himself if they could make such a mess in just two years.

At this time, there was no wind in the four fields, and such a dense column of smoke came out of the courtyard on the opposite bank, Zheng Hui guessed that there should be an open furnace forging something.

Han Qian didn't have any intention of hiding it, he didn't want to get caught up in the busy transactional work, so he had to find some excuses for the next leisure time, and smiled with the third prince

"I've thought there could be some improvement in the Scorpion Cannon, and I've built a forged house in the courtyard, hoping to successfully forge a steel bow arm - would you like to take a look, Your Highness, or maybe we'll have a feast on the other side of the river at night?"

"Good!" Yang Yuanpu ignored Shen Yang's objections, turned his head and said, "If we don't go back to the city tonight, we will live in Yongchun Palace!" ”

The prince is not allowed to go out of the city casually, and he is not allowed to stay overnight when he goes out of the city, this is a rule that Shen Yang cannot change, but he also knows that the three princes should not be restrained too much, so he immediately called Gao Chengyuan and Zhang Ping over, and asked them to send someone to the city immediately to report to the Inner Servant Province to report the matter of the three princes staying in Changchun Palace tonight.

Han Qian waved his hand to signal the Han family soldiers on the other side of the river, and ordered Lin Zongjing and Guo Nuer to come over by boat to pick up everyone and more than 100 guards to cross the river to the other side.

The courtyard of Yandangji, compared to the Yongchun Palace Manor, is much more dilapidated and simple, and it has just been built in a big way, there is nothing to see, and everyone crossed the river.

Han Qian directly asked people to drag the bow-arm scorpion cannon trial-made with Zhemu material out of the west cross courtyard for practice.

Stainless steel is difficult to refine, and the newly built bow scorpion cannon still uses eight tuomu bow arms as a charging mechanism, and the whole scorpion cannon is only one zhang long, which is much smaller than the normal whirlwind cannon, and the size can be placed on the top cabin and the fore and aft decks of a three-masted sailing ship.

A two-thousand-stone three-masted galleon can hold about six scorpion cannons.

However, the scorpion cannon made of Takumber is still a little less interesting, and at present, it can throw a thirty-pound stone projectile to two hundred and thirty or forty steps away, and this distance is exposed to the best range of the opponent's bed crossbow, and it needs to be protected by a very thick wooden battlement wall.

All kinds of things add up, and the warship will also become bloated.

Han Qian asked the Han family craftsman to practice the use of the scorpion cannon, and explained to the third prince and Shen Yang and others, "The Tuomu bow can charge and shoot crossbow arrows, but it is still not enough to throw stone bullets, I think that if the bow arm can be cast in stainless steel, it may be able to throw more than 50 catties of stone bullets, and then the scorpion cannon can be placed on the head of the city or on the warship to fight-the fire and furnace on the side of the training room, it is a trial to make a stainless steel bow arm, but it may not be successful in three or five years!" ”

Yang Yuanpu said excitedly

"Three or five years or longer, as long as Master Han can make such a sharp weapon and dedicate it to his father, it will be a great achievement, and then my Great Chu soldiers and horses will be invincible!"

Han Qian looked around, seeing that everyone didn't have a particularly sense of urgency, no one thought that it was a waste of time for him to spend three or five years trying to make a stainless steel bow arm, thinking that in everyone's hearts, maybe he still felt that Emperor Tianyou could control the situation.

It's no wonder that Emperor Tianyou has laid such a big foundation, as a courtier, a few people dare to question the prestige of Emperor Tianyou, even if Xu Mingzhen, Ma Yin and others are ambitious at this time, they don't dare to act rashly.

Especially at the moment, when Emperor Tianyou already has an obvious inclination towards the Junwang Mansion, everyone may feel that it is better to follow the steps step by step.

Han Qian sighed slightly in his heart, secretly thinking about what he wanted to do, it seemed that he still needed to wait for the next opportunity.

Shen Yang couldn't guess what Han Qian was thinking and why he spent so much energy and time on this kind of thing at this moment, but he was not as optimistic as the third prince Yang Yuanpu, and asked Han Qian suspiciously

"The top-grade Hundred Refining Knife is worth hundreds of thousands of dollars, and it can be indomitable, the stainless steel bow arm you want to make is so much larger than a Hundred Refining Knife, even if it is really possible, the price may not be too high, right?"

Zheng Hui is also good at learning from the world, and secretly shook his head and said, "I'm afraid it's difficult to succeed." ”

"If you don't try, how do you know if you can make it?" Han Qian smiled slightly and said.

To be honest, Han Qian didn't think that he could really cast steel bow arms in batches in three or five years, after all, as a power accumulation machine, it was much more demanding than ordinary pure steel parts.

What's more, with the current urgent situation, it is impossible to give him more than three years to ponder these things calmly.

And he insisted on trying to cast the steel bow arm, on the one hand, through some people told Emperor Tianyou that he was now very patient to settle down to do something, on the other hand, compared to the steel bow arm itself, he actually thought in his heart, through practice to touch the current steelmaking and steel parts forging process, to see if there is anything to improve.

The price of Jinling iron is only ten yuan a catty, while ordinary crude steel costs more than 100 yuan a catty, and the hundred steels that can be used to cast high-grade swords are even more expensive than gold.

Han Qian was quite free during this time, how could he not put some thought into this?

Even if it can only take a small step forward in the world's steelmaking technology, its benefits are by no means comparable to three or five or even three or five hundred scorpion crossbows.

Han Qian first showed weakness to the enemy in Xichuan, and then lured a large number of elite Liang troops into a death trap-like pocket array in the city to deal a devastating blow, relying on two sharp weapons, which had never been seen in the world before, the scorpion crossbow and the whirlwind cannon.

Although after the war, Han Qian presented the atlas of making scorpion crossbows and whirlwind cannons, so that they could be promoted among the Chu army to defend against the enemy, at this time, he tried to further transform the scorpion cannon in Yandangji that could be easily installed on warships and city walls.

Next, Han Qian invited the Third Prince, Shen Yang and others to the forging room in front of the West Cross Courtyard to actually see the forging process of the stainless steel bow arm.

It was a hot summer, and several young craftsmen in the adobe house were shirtless, sweating down, and the charcoal fire in the hand forging furnace was red-hot, and the hot gas was like a fire, so that people could not bear to stay in the adobe house for a while.

Shen Yang, Zheng Hui, and Zhang Ping accompanied the three princes, although they stood outside the adobe house, they were also sweating, and saw that there were two hand-forged furnaces built inside, and the craftsmen of the Han family took the thick iron rod with tongs and put it into the concave furnace to burn it red, and a few slaves and maids were taking the leather bag air row to blow into the hearth from the bottom, and after the iron bar was burned red and softened, the iron ore powder was sprinkled little by little, and then the fire tongs were clamped and kept rolling.

Zhang Ping, Wang Lin and others just watched the excitement, and they felt that it was too hot to stand outside, but Zheng Hui knew that this was a steel frying method that had been handed down since the end of the Han Dynasty.

Although Zheng Hui was the general of the army, he was born in the Zheng family of Huangzhou, and was a well-dressed family, and then because of the frequent wars in Jingxiang, the children of the Zheng family gave up literature and martial arts, but they were also full of poetry and books since childhood, so after the Shengsheng in Xiangzhou City, he was appreciated, and was directly promoted to the county palace as a counselor and military counselor.

In the ranks of the county king's mansion, the counselor and the military are second only to the three positions of the county prince, Changshi and Sima.

After the victory in Xichuan, many people judged that the three princes were crowned kings and princes of the county, and Han Qian should be appointed as a councillor of the palace and a military officer because of his merits, who would have imagined that Han Qian would only be engaged in literature and lead the left division in the county palace in the end.

There are also several iron-making factories in Huangzhou, and the smelted iron is exported to Tanyue, Zheng Hui naturally knows very well in his heart that this method of frying steel is crude steel, which is acceptable for making agricultural tools, but if you want to build a blade, you have to use the traditional forging method to carry out repeated hammering.

Crude steel is mixed with a large number of impurities, forging to remove impurities, the weight will be reduced, and the weight will not be reduced after 100 refining, which can be regarded as success.

However, considering the direction of deformation and the complexity of the bow arm, there is considerable attention to the quenching.

Zheng Hui looked at the small adobe house, crowded with more than a dozen craftsmen and slaves of the Han family, and secretly felt that if he continued to toss like this, he might not be able to cast a working bow arm in three or five years, and even if Han Qian found a way to cast a steel bow arm, the manufacturing cost of a scorpion cannon would probably be surprisingly high, right?

Zheng Hui also noticed that Shen Yang's brows were frowning slightly, and he thought to himself that Han Qian was still dissatisfied with the military merit reward and punishment this time, so he deliberately found such a thing so that he could slack off the affairs of the county prince's mansion?

Thinking of this, Zheng Hui looked over to Han Qian, but saw that he was staring at every move in the exercise room more attentively, not knowing what he was thinking in his heart.
