All of them here are great craftsmen, because there are Huang Hankai golden fingers to climb the science and technology tree, it is possible that these people are the most advanced talents who have mastered the most advanced technology such as steelmaking, ironmaking, forging, drilling and so on.

At this moment they all saw a sketch of a flintlock pistol drawn by the head of the house, with detailed instructions and drawings on the barrel.

Of course, this is Huang Han once again opened the golden finger to arrange for the blacksmiths to try out the flintlock rifled gun, and gave instructions that this is a top secret, and all the technology must not be leaked.

Compared with rifling the barrel, the technology of Mini bullets is simply not worth mentioning, Huang Han took out the drawings and even Yang Laoshi, who was not literate, understood it.

Shen Cunli's knowledge is much higher than that of Yang Laoshi, and he comforted when he saw that the master of the family told the blacksmiths involved in the production of new products not to let the technology leak out:

"My lord, please rest assured, the quality of the steel produced by the Huang family is second to none in the Ming Dynasty, such good steel is rare, it is not easy for Jiannu to get such materials, their blacksmiths are not really hardworking, it should be unlikely to use rare good steel to try to make such a complex bird gun."

Huang Han emphasized: "Not only must we guard against Jiannu, but also the Guan Ning army must be guarded, even if someone from the imperial court is not personally accompanied by this official, no one can enter the factory area where firearms are produced, and violators will be killed." ”

Yang Laoshi hurriedly said: "My lord, so far, only when Kaiping was in Kaiping, Mr. Xu once came to see us making bird guns and carrying guns, and I didn't find anyone from the imperial court asking to see our factory. ”

Huang Han didn't care too much about other techniques, only the use of Mini bullets and flintlock rifled guns was the most important technology, because the terminator of the front-loading black powder gun was the Mini gun, and there was no front-loading gun technology in the black powder era that would surpass this gun.

Huang Han thought that when he had an army of 5,000 men and all equipped with Mini rifles, it would not be a problem to sweep through Liaodong, but it was a pity that he could only capture all the cities occupied by Jiannu.

Jiannu was mainly cavalry, and they found that if they could not defeat the "Red Banner Army", they would definitely flee all over the grassland, and they would not be able to completely eliminate them.

Huang Han and other great craftsmen also talked about the principle, accuracy and firing range of the Mini gun after reading the drawings, and these great craftsmen were very excited to hear it.

Yang honestly took the drawings and pondered for a long time, and said honestly:

"My lord, this new type of bird gun so processed in order to eliminate the danger of explosion of the gun pipe must be properly thickened, it is estimated that the processing difficulty will not be small, to meet the requirements of adults, the production cycle of a gun is probably full thirty or forty days, and the scrap rate should be very amazing."

Shen Cunli also said: "It's no problem to meet the requirements of adults, but the cost is relatively high, the cycle is relatively long, and the output cannot go up. ”

Huang Han knew that rifling in the barrel of a gun was a meticulous job in this era, and he would not be strict about the output, but emphasized the quality.

He said: "You don't have to consider the construction period and don't care too much about the cost, these should be studied after the product is formed, and now the top priority is to produce a high-quality product, which can only produce one or twenty pieces a month." ”

Seeing the head of the family say this, the masters were relieved, and they all said that they would do their best to produce this terrifying good gun, but they didn't understand why the head of the house named the good gun that was about to be put into production the strange "Minny Gun" in Guli.

Spring is coming, the tunmen are busy with spring ploughing, the soldiers are busy with training, and the workers are busy with production.

Supervisor Sun Chengzong sat in Shanhaiguan and began to lay out fortress battles, Yuan Chonghuan twice built the Dalinghe City that was destroyed by Jiannu twice, and the Ming army was ready to mobilize the people to build.

In early February, Huang Han joined forces with Zheng Xiuwen, Gao Youmou and the three patrols who were busy planting cowpox to build Dalinghe City.

In order to show his loyalty, Gao Youmou used the connections of the Gao family to find some officials to jointly deny the construction of Dalinghe City.

Huang Han's recital is more pertinent, and he clearly points out that the commander who builds the fortress must have the self-confidence to be able to hold on to the fort before it can be implemented, otherwise it will not cost the people and money?

If the commander insisted on building Dalinghe City, then the city should be held for three or five years before it can play its role, which is barely worth the money.

If it had become a grave for burying the Ming army in less than half a year, then the commander who advocated the construction would not have escaped the blame.

Huang Han's implication was to let Sun Chengzong be careful, and when repairing the city, he had to think about how to defend the city, don't just pat his head and do it, which eventually led to heavy losses for the Ming army.

Originally, Liang Tingdong was very much in favor of Sun Chengzong's proposal to build Dalinghe City, but later found that more than a dozen songs led by Huang Han were all eloquent, and the Ming army might be wasting money and food in vain, and Dalinghe City could not be defended at all.

Liang Tingdong then changed the charter and also opposed the construction of Dalinghe City.

The end result? In the spring, Sun Chengzong went out of Shanhaiguan to patrol the border, and he took his men and horses from Qiantun Acropolis and Ningyuan to Songshan City and Jinzhou. Then from the three passes of Shimen, Yanhe Pass, Sanxie 12 Road, from Shitang through Pinggu, through Panshan into Jizhou back to the capital.

Sun Chengzong met with the Son of Heaven and said that he was the first minister of the feudal territory, the commander of the eight divisions, the garrison of Jizhen, the preparation of Liao Town, the appropriateness of Jiliao and Liao, and the restoration of Dalinghe City.

The emperor was really suspicious, and he thought that trustworthy people could get support no matter what they did, so he agreed to many of Master Sun's proposals on the spot.

Of course, the performance of the children of the Huang Han Dynasty was selectively forgotten, so the four-year history of Chongzhen was still the same, and the Ming army was about to lose troops in Dalinghe City.

In mid-February, the military department Shangshu met Gao Youmou, a general of Zanhua sent by Huang Han, but Huang Han was unwilling to give someone a handle, so he did not write a letter to contact Liang Tingdong and sent someone for an interview.

Gao Youmou explained clearly that Huang Han was worried that the Ming army might suffer a big loss in the Battle of Daling River, and that the military department Shangshu might bear the responsibility.

Liang Tingdong didn't know that Chongzhen's military department was in high danger, and the lessons of his predecessor Wang Zaijin and Wang Qia were unguarded, so he took advantage of the fact that he had no feet and a big face and an ugly face to decisively write a letter to resign.

He has been in the center for more than a year, and he still has some ways to show his military affairs, and the emperor trusts and relies on him, but he has repeatedly been impeached by the emperor for accepting bribes and promoting private individuals.

Seeing that Liang Tingdong took the initiative to resign on the grounds that he was tired and his health was deteriorating this year, and it was really difficult for him to be qualified for the important post of secretary of the Ministry of War, he agreed to Liang Tingdong's return to his hometown to live idle.

Therefore, Liang Tingdong is equivalent to retiring, and Xiong Mingyu, a sage from Nanchang, Jiangxi, who was born as a jinshi, was appointed as the secretary of the military department.

Liang Tingdong has a good relationship with Zheng Guochang, Huang Han followed suit, and now he has been replaced by Xiong Mingyu, seeing that there is no help, and even the food and salary in hand have to bear more drifting.

Houjin captured hundreds of thousands of Han Chinese and obtained many craftsmen, some of whom knew how to cast Hongyi cannons.

Under the leadership of the traitor craftsman Liu Han, the Later Jin army obtained the technology of casting cast iron cannons.

At the beginning of the first month, although the artillery cast by the Han craftsmen was scrapped eighty percent, the red gang still succeeded in getting six self-produced cannons, and he knew that the success rate of twenty percent was already good, so he gave Liu Han a heavy reward.
