On the third year of the Yuangui, the Military Industry Department of Lanxianghua Digging presented Yu Qiuping with a New Year gift that made Yu Qiuping ecstatic - a three-pound cannon that successfully imitated it.
After nearly a year of hard work, the Military Industry Department of Lan Xianghua dig finally successfully copied the first big tube. Since Chang Panbei had almost no expansion in the army in a year, the production of long cannons and short knives gradually slowed down, the Military Industry Department devoted nearly 80% of its power to the imitation of the big tube; and the brothers brought back by Ida Kangqing also gave all the drawings and experiences they knew. In addition, Yu Qiuping bought three big tubes for them to test and continuously experimental funds, the Military Industry Department finally succeeded.
During this year, they made and abandoned countless abrasive tools, wasted countless copper, iron and metals, and almost all the funds they consumed could afford to spend a year. Yu Qiutai, under the huge pressure from Congress and Yoshi Semine, supported them in an opposition to conduct the experiment, and finally achieved success.
However, in front of Yu Qiuping, it was still a pitiful three-pound cannon with little power. This was the only result of the Military Industry Department's efforts in one year. Its range was about 30 meters and it fired only solid iron-spherical shells, which was difficult to have any lethality to the construction of the earth and rock structures. If Lan Xianghua Digg had not repeatedly assured the Congress and Yoshinomi Seminyama that with the experience and data on casting the gun for the first time, casting the gun would be faster and faster in the future, and the cost would be less and less, and the Military Industry Department's casting gun plan would be almost rejected.
However, this three-pound cannon became Yu Qiuping's treasure. He asked the Military Industry Department to build a small cannon truck for this cannon, and used four horses to pull it away, and generously equipped it with a gun team of about 20 people. There were gunners in it, and they also trained artillery skills day and night to improve accuracy and firing, just like when Yu Qiuping was training iron cannoners in the past. There were also many auxiliary troops such as coachman, shield soldiers, loaders, etc.
However, as the gunners were practicing, Yu Qiuping found something wrong. No matter how hard they practiced, their level improvement was always slow, and they could not keep up with half of the progress of the iron gunners back then. After communicating with Idan Kamkyung, Yu Qiuping finally realized the problem. No matter how difficult the iron cannon is, it is enough to aim correctly and shoot a straight line to the person. However, the big tube is different. The trajectory of the shells shot by the big tube is a parabola instead of a straight line. The elevation angle of the big tube is filled with gunpowder, and the estimate of the distance between the enemy and us cannot be practiced overnight. Yu Qiuping saw two gunners with his own eyes. Even if they practiced very hard, the distance was not good. They thought it was about 60 meters away from clearly 10 meters away. They thought it was 50 meters away from 50 meters away. If they were not even accurate in the distance, how could they expect them to calculate the angle of the parabola.
Yu Qiuping realized that artillery is a technical army, and there are special artillery academies in Europe for training. It is unrealistic to expect artillery and infantry to be as easy as iron gunners. So Yu Qiuping temporarily stopped blind training of the gunner's door, but instead, with Takenaka Shigeji, led a group of smart staff members to try to compile an artillery training manual.
Yu Qiuping first tried to develop a set of methods to estimate distance - which was really not easy. Because artillery requires accurate parabolic shooting, the distance must be accurately grasped. However, Yu Qiuping is also a student with systematic mathematics education after all. After thinking hard for several days, he stumbled to explore a thumb distance measurement method that was very similar to the European artillery distance measurement method. This method is based on the theoretical basis of trigonometric functions (or similar triangles) and calculates the distance between himself and the target by establishing two similar triangles.
The distance finder raises one of his thumbs and uses one eye to observe a target with a known approximate height in the distance (such as the opponent's foot lightness - the height is generally around 1.55 meters, or some trees and hills measured in advance). By feeling the ratio of the target to the height of his thumb, and then calculating the distance from his thumb to his eyes, you can calculate the approximate distance from the target.
The method proposed by Yu Qiuping surprised the members of the General Staff and the gun team. They never thought that there was a way to calculate the distance step by step from time to time from time to time. They thought that if they wanted to know the length of the distance, they could only use a ruler to measure it.
However, although Yu Qiuping came up with a method, this calculation method was too difficult for those who were not educated. No one of the members of the gun team could learn these things. Yu Qiuping had no choice but to hold an exam for Yu Qiu's family, trying to screen out some people with more mathematical talents to be gunmen and range finders in the gun team.
To his surprise, Naoe Seimonmaru was the one with the best test scores! Uzukihei and Naoe Tadaehide did not notice that this child actually had such a good talent in mathematics. Uzukihei would give Yu Qiushang, Yu Qiuyu, Yu Qiuguang, Tusong, Naoe Seimonmaru some basic arithmetic courses, but Naoe Seimonmaru's performance has never been outstanding. I don't know why he did so well this time, and he was more than ten points higher than the second place Kinkizu, who was named Chishoutao.
However, Naoe Seimon Maru is not yet a 10-year-old man. This year, it is too early to join the army. However, after consulting Naoe Tadaehide's opinion, Naoe Tadaehide supports Yu Qiuhei's involvement of Naoe Seimon Maru into the artillery group. He felt that this child was so old, and it was time to go and practice and make some contributions to Yu Qiu's family. So Yu Qiuhei no longer refused and asked Naoe Seimon Maru to be the deputy of the cannon leader Chishoutao. Yu Qiuhei personally opened the class and taught trigonometric functions skills to those in the top ten of the exam results.
After selecting a brand new gun team members, Yu Qiuping took them to measure the elements of the big barrel. The relationship between range and gunpowder usage, the relationship between elevation angle and landing point, the combination of elevation angle, range, and gunpowder loading... After a long test, a large amount of data was measured. After Yu Qiuping and the gunpowder members' hard calculation and summary, a three-pound gun training manual was finally compiled, and artillery training can also be on the right track. The Military Industry Department of Lan Xianghua Dig also began to continue to produce more large barrels to ration the troops.

On February 13, 1572, Yu Qiuhei suddenly assembled troops in his rank and sent troops to Nan Hanoi before the end of the spring plowing. Oda Nobunaga sent someone to instruct Yu Qiuhei around the Chinese New Year and asked him to attack Takaya Castle before the end of the spring plowing. Because one-third of Yu Qiuhei's troops were regular soldiers (that is, combat soldiers). However, only one-seventh of the troops of the Sanhao family were regular soldiers, and the rest were militias that needed to participate in spring plowing and autumn harvesting, and were mobilized only during the slack farming. Although Yu Qiuhei recruited auxiliary troops to attack during the spring plowing, it would have a significant impact on the agriculture in the territory, but the impact on the Sanhao family would be greater. This method of self-damaging eight hundred and hurting one thousand enemies was Oda Nobunaga so that his subordinates could use it without any psychological burden, but Yu Qiuhei had to obey orders.
Yu Qiuping's dispatch of troops made the merchants in the House of Commons very dissatisfied - when the farming period was busy, it meant that the harvest this year would be affected, and the treasury would face pressure. The people may have a shortage of life due to insufficient harvest, which reduced their purchasing power and brought trouble to the merchants' shops. What's more serious is that the labor required for a large number of factories opened by merchants came over in the slack farming period. If Yu Qiuping draws men to war, many workers would have to stay on the vacancies of recruitment on the top of the territory to complete the spring plowing of the territory and cannot work here - this would have a huge impact on the factory. However, the previous constitution did not restrict Yu Qiuping's right to send troops. On the legal level, Yu Qiuping could do whatever he wanted.
The House of Commons then decided to make up for the loss and formulated a new decree: If Yu Qiuping wanted to carry out large-scale military activities during busy farming, such as spring plowing and autumn harvest, it must be passed by half of the parliament. After hearing about this bill, the people of Yu Qiu's family were furious - the parliament not only held the wallet, but now they even want to interfere with the military command of Yu Qiu's family?
However, Yu Qiuping assembled troops during the busy farming season and also offended the little wealthy families. Although their income has nothing to do with the harvest of the territory, it is also the land they passed down from generation to generation. Therefore, in the upper courtyard composed of the little wealthy families, except for the four little wealthy families in Mino who voted against it, everyone else agreed to the resolution.

While the internal dispute was being quarreled within the parliament, Yu Qiuping's military operations were launched without any restrictions and attacked Nan Hanoi.
The Miyo family did not notice that Yu Qiuhei gathered troops in the territory, but did not expect that Yu Qiuhei would actually gather the entire army to attack at the risk of spring plowing. Because Yu Qiuhei has always been a safe and cautious person, and rarely acted decisively and unexpectedly attacked. They did not know that Yu Qiuhei's attack was forced to push by Oda Nobunaga behind the scenes. Miyo Yu Qiuhei Nagata and Miyo Masayasu, located in Takaya Castle, were caught off guard and had to gather troops together. However, before they assembled a force that was enough to compete with Takayaba and 24oo warriors, Yu Qiu's army had already broken through the Yamatokawa defense line and surrounded Takaya Castle.
At this time, the Miyo family had not yet been able to assemble all the troops in Nanhanoi in Takaya Castle, and many people had to scatter in the small town to fight. Under the slightest order of Takamasa of Takamasa of Takamasa of Takamasa of Takamasa of Takamasa of Takamasa of Takamasa, many of the small families of Nanhanoi who had been suppressed by the Miyo army revolted again, and cooperated with Yu Qiupi's troops to attack the Miyo family's stronghold in Nanhanoi. Within 10 days, the entire Miyo family had fallen under Yu Qiupi's control, and Takama Castle became an isolated island. After the autumn harvest, the Miyo family hurriedly assembled the troops to come to Kinki to fight. Oda Nobunaga was not willing to be outdone, and gathered the largest army that Ohashi, Mino, Ise and Minoe could mobilize, and prepared to compete with the Miyo family.
