Zhang Zai brought his disciples into Beijing, causing a sensation in the capital.

Since Wang Qi, Lu Dafang and Han Gang recommended Zhang Zai together, not only Shilin has been waiting for this world-famous Confucian master. Even the people in the capital were curious - the great Confucian who could teach a disciple like Han Sheren, the weapons supervisor, and made Wang Xianggong reject him several times outside the capital, was certainly not a simple figure.

Due to the preaching of various famous Confucians, the behavior of burying one's head in the commentaries of the Han and Tang dynasties and diligently assidly in the chapters and sentences is no longer to the liking of today's scholars. Everyone wants to find an explanation that suits their own hearts from various schools of thought.

Among them, Qi Science, which has always claimed to be 'big heart', especially the four sentences of 'establishing a heart for heaven and earth, establishing a life for the people, continuing to learn for the saints, and opening peace for all generations', is most in line with the spleen and stomach of these young scholars who are determined to change everything - Zhang Zai's reputation in Shilin is not entirely based on Han Gang's invention.

Zhang Zai was ordered to arrive in Beijing and first went to the south of the city to settle down according to the rules. But Han Gang had already helped him rent a suitable house in the capital. And just near the house, there is a quiet temple, although Guan Xue severely reprimanded the Buddha, but it did not prevent Zhang Zai's disciples from living in the temple - Han Gang also scattered a sum of incense money for this, so that the monks inside were very concerned about the arrival of Guan Xue's disciples.

Zhang Zai kept the rules of the court and temporarily settled in the south of the city. The Confucian scholars in the capital visited for several days, and it was much more lively than the retainer of the ruling minister, so that the post guards in the south of the city were overwhelmed, and they looked forward to Zhang Zai moving out of Lu as soon as possible.

However, Zhao Ji did not summon Zhang Zai at the first time, although he also wanted to meet this world-famous Confucian earlier, but the prime minister's face had to be taken into account, and Zhang Zai's official position was not good, so he felt that he would wait a few days.

After resting in the post house for a few days, although he also met many guests during the period, Zhang Zai's spirit was still much better. I can also come out to visit relatives and friends. One day free, he even came to the ordnance supervisor to take a look at Han Gang's invention.

Such as the plate armor bureau and the bow and crossbow courtyard, even if Zhang Zai is inconvenient. But the workshop that builds windmills and waterwheels doesn't mind being visited, and the utensils that are all in the world don't need to be kept too strictly secret. Moreover, Zhang Zai is Han Gang's teacher, and in the eyes of the world, there is no need to hide it at all.

In a courtyard in the corner of Xingguofang, several windmills were whirling.

This is the workshop where the Ordnance Superintendent built windmills and waterwheels. Windmills are large and small, but they are all similar in shape. With the exception of one one, four long fan blades spread out in a cross shape, with the central axis parallel to the ground, very different from other windmills, but still rotating against the wind.

"This windmill is very special." Zhang Zai looked up with great interest.

"This one is a new model that the students asked the craftsmen to build, and we want to try to see which is better than the usual windmills."

When it comes to windmills in later generations, it is the cross-shaped stretching of four fan blades, but at this time, the windmill that Han Gang saw had a vertical central axis, and seven or eight fan blades hung on the shaft and pulled out a long pole in a circle, like a mast that pulled up the sails of a ship, but there were just a little more sails hanging on the mast.

Which windmill is more efficient, Han Gang also knows in his heart. At least a thousand years later, he still remembers which kind of windmill the wind turbine was modeled on. However, today, the materials are different and the structures are different, so it cannot be asserted. What we need to do now is to have people build both windmills and compare them.

"Sir must have heard a little bit about the pupil's affair with the water mill - it was written in the letter the other day." Han Gang explained the reason to Zhang Zai, "Since the students have snatched their places in their hands, it stands to reason that they should return the one that can be counted." Although it is not as convenient as the hydraulic drive, the water mill is actually useless in the winter, and the wind mill can come in handy in the winter. Wind power is used when there is wind, animal power is used when there is no wind, and it can be used in all seasons. ”

"It's good that things are fixed." Zhang Zai nodded and smiled, and then advised: "Yukun, although you are good at inventing, it is also a food that takes the food from your mouth, so you must not act carelessly." ”

"Students understand." Han Gang bowed his head to be taught, and he knew that the track of the road had made many laborers unemployed, but he still let Zhang Zai know the way.

……………………

It was not only Zhang Zai who arrived in the capital, but two days later, Chong Jianzhong brought a message to Han Gang, saying that Wang Sunchen was going to be transferred to Yanyan Road and Yanzhou East Road to inspect it.

Wang Sunchen wanted to transfer to Yan Yanlu, which was a kind of suggestion. What kind of idea is the new deputy head of the soldiers and horses of Yanyan Road, that is Sima Zhao's heart, and everyone knows it. In a few days, maybe he will go to the table again to ask for Yokoyama.

Since he has this thought, he naturally wants to gather elite soldiers and strong generals around him, and he is an elite and strong general who listens to his orders - in the past few years since he left Yan Yanlu, there have been frequent personnel changes. In order to be able to get out of the army, he needed a group of officers who were also fighting with him.

Although Wang Sunchen was at the beginning of Xihe Road and was famous, now he can even go to the first level of the capital prison after two more years. But after all, he came from a breeder, and the seed can be trusted by him. With this young general who is well-known in the army, the certainty of taking Yokoyama in the north is one more point.

But Han Gang didn't like this order, in his opinion, with the current situation of Xihe Road, the time was ripe to attack Lanzhou. If you want to make a move on Xixia, it is better to start from Xihe Road first. At this time, the core generals who were transferred to Xihe Road actually outweighed the losses.

The local garrison on Xihe Road has been able to achieve most of its self-sufficiency, that is, weapons and armor, if an ordnance workshop is set up in Taoshan Supervisor in Minzhou, it can still be produced and sold by itself - although this only refers to peacetime, after the war, military spending and grain will definitely have to be replenished from outside, but consumption will never be.

In addition, in the city of Lanzhou, Yu Zang Huama has already moved his mind to deviate from Xixia and secretly communicate with Xihe Road. As long as he defects and doesn't even have to make a big move, Lanzhou City can be taken.

Lanzhou, not only can the Tibetan tribes be separated from the Western Xia, but the front can also be directly pointed at the Hexi Corridor occupied by the party members, as long as the Luoluo River [Zhuanglang River] goes north and captures the Hongchi Ridge [Wusheling Ridge], the old Silk Road can be restored. And more importantly, Lanzhou crosses the mountains to the north, which is the hinterland of Xingling in Western Xia. This was a greater direct threat to Western Xia than the attack on Hengshan on the Yanyan Road.

In fact, there is no need for Han Gang to say these points, as long as people who are familiar with Western affairs can see it. Naturally, Wang Anshi's father and son can also see it.

"But who will lead the troops to Lanzhou?"

"How could the seed of Yanyan Road be willing to fight for Xihe Road?"

Han Gang came to visit Wang Anshi overnight, not to stop this. This matter is most likely the Son of Heaven's proposition, Wu Chong and Wang Shao in the Privy Council have not been able to stop it, and Wang Anshi is not good at patrolling for everyone to oppose the Son of Heaven's opinion. He just planned to promote the capture of Lanzhou - Lanzhou, Xihe Road has the danger of mountains and rivers in the north, and it will be safe. But Han Gang didn't expect that Wang Anshi and his son were already preparing for the capture of Hengshan.

"Both sides of Xihe and Yanyan can do it at the same time, and the Great Song Dynasty has enough strength to support the two places to start a war at the same time. Not necessarily. ”

"It's just Hengshan, it won't alarm the Liao people. If the two fronts move, how will the Liao people sit idly by? Wang Anshi shook his head and said, "Yukun, don't forget that Bingchang is already a concubine of the Liao State now." ”

Bingchang is a concubine of the Liao State and married a Khitan daughter with the name of a princess. Although this kinship was just a cover most of the time, if the Great Song Dynasty attacked on a large scale with the purpose of destroying the country, the Liao State would have every reason to send troops to intervene, which could not be ignored.

Wang Yan also smiled: "Capture Hengshan first, how can Yu Zang Huama have the courage to resist the heavenly army again?" The city will inevitably be invested. It's a win-win-win ”

"Yukun, you are from Xihe Road, but it is a matter of the overall situation, and Hengshan must be taken down first."

Of course, Han Gang knows the importance of Hengshan, and once he has this place, the hinterland of Guanzhong will be able to sit back and relax. And Lanzhou is only about Xihe Road, which is too far away from Guanzhong. Therefore, it is not unreasonable for Wang Anshi and Chong Ge to value Hengshan, but why don't they want to think about what kind of response the Son of Heaven will make under the threat of the Liao? After suffering a loss, can't you still remember the lesson?

"The Liao people will not threaten a Lanzhou city. But once Hengshan is captured, or even raised troops to attack Hengshan, the Liao people may immediately intervene. "There is still a big gap in the strategic significance of the two places, and there is also a big difference in fame, which does not need to be said by Han Gang, "Once the Liao people intervene, no one can say for sure whether they will continue to fight or withdraw their troops." If the official army retreats from the Liao people, will Yu Zang Huama still have his heart set on China? ”

Zhao Ji must swear that he is not afraid of the Khitan at this time, but what will happen when it comes, Han Gang is not optimistic at all.

Wang Anshi sighed and said, "The imperial court is going to let Kumamoto go to Xihe Road and be the governor of Xizhou. ”

In recent years, the Great Song Dynasty court not only raised troops in Xihe and Jingnan, but also subdued Qiang and Barbarian. In the southwest, there were also Xiong Ben soldiers who opened up territory for the Great Song Dynasty. However, his achievements are not as good as Wang Shao's, his fame is not as good as Zhang Dun's, and he is suppressed to the point of bleakness, but his ability is impeccable, and he is also a first-class talent.

"Kumamoto has indeed achieved something in the southwest, but he has no experience in Longxi affairs." Han Gang opposed the appointment. With Kumamoto as the person chosen to go to Xihe, he did have the intention of seizing the opportunity to capture Lanzhou, but Kumamoto was not familiar with the local situation, and he was afraid that he would delay the fighter, so it was better to transfer Shen Kuo.

“…… Yukun, are you planning to go back to Xihe Road? "Because Wang Anshi served as the prime minister, Han Gang recently invited himself out of the table, and Wang Yan naturally has associations in this regard.

Han Gang was slightly angry in his heart, is he such a person? …… No wonder he didn't mention Kumamoto's trip to Xizhou at first, because he was afraid that he would rush to go after hearing about it.

He narrowed his eyes and laughed: "The junior brother has something to worry about on Xihe Road, but the ordnance supervisor also has something to worry about, the hydraulic forging workshop has not yet been completed, and the plate armor bureau has yet to be run-in." It is also wanted to promote orbits in the mines, in addition to the improvement of the spacecraft. There are so many things that each one is a little hard to let go. ”

"Yukun." Wang Anshi said sincerely, "Since you also have such thoughts, then stay in Beijing for a while." There are many places in the capital that need you, so don't rush to go out. ”
