The person Sun Kewang brought from prison was none other than Zhao Shichun, who had failed the exam in Beijing, no wonder Gao Junshan couldn't help laughing when he saw him, because he saw Zhao Shichun's embarrassed appearance.

"King Qin, why are you making fun of me?"

Gao Junshan took Zhao Shichun's hand and said: "It's not to make fun of you, it's just that your role has changed too quickly, how can a student be imprisoned?" ”

"Ahem! Don't mention it. Zhao Shichun said in frustration, "I regret that I shouldn't have left you King Qin in the first place!" ”

Gao Junshan asked with concern: "How do you say this?" ”

Zhao Shichun seemed to see a long-lost relative: "Two months ago, I left from you, and within three days of leaving, I was arrested by the official army, forced me to pay something, and forcibly searched my coils. I told them that I was just a student who went to Beijing to take the exam, and they even went even harder, coercing me to write letters to my family asking for money, and sent me to prison. ”

Gao Junshan put his sheepskin jacket on Zhao Shichun's body: "These dog officials can only fish and eat the people!" ”

Zhao Shichun gratefully left tears: "I studied hard in the cold window, went to Beijing to study, not to be prosperous and rich, but to help the society and expel the Tartars." ”

Then, Zhao Shichun denounced this dark world again, and then he happily threw himself into the team of Gao Junshan. Historically, Zhao Shichun went to Beijing again in Chongzhen in the seventh year to catch up with the exam, Chongzhen took the exam again in ten years, and explored flowers in high school, that is, he embarked on the road of official career with the qualification of third place.

………………

On the sixth day of the first month of the fifth year of Chongzhen, the first snow of the new year fell in Huanxian County, the whole county was covered with snow, the snow stopped at noon, and the adults of every household came out to clear the snow, groups of children, in snowball fights, snowballs, and sledding.

Huanxian was called Huanzhou in ancient times, the Ming Dynasty was only downgraded to a county, so the pattern of the street is also similar to the state capital, the houses on both sides of the street are lined up one after another, tea shops, wine shops, pawnshops, foot shops, butcher shops, temples, blacksmith shops, ceramic workshops, cloth workshops are lined up, there are silk satin, jewelry and spices, incense paper horses, etc.

In the afternoon, the number of people shopping in the market gradually increased, and soon there was a prosperous scene of crowds and traffic.

Except for the big banner with the word "Chuang" hanging high at the city gate to show that the city was occupied by the rebels, there was no rebel army walking around the market in the city. Gao Junshan strictly ordered his subordinates to stay in the barracks and not to harass the people on the streets.

The east, west, north and south were stationed in the four teams of Red Army Friends, Li Busi, Hao Shaoqi, and Ma Jinzhong, and Sun Jiye still held on to Tiejiao City.

As soon as they moved into the county office, Liu Fanglan and Han Yuyan reported the good news that he was about to become a father. Gao Junshan arranged for two experienced aunts to take care of the ladies.

After occupying Huanxian for more than a month, Li Laochai and Lone Ranger Wolf on the Anhua side never sent anyone to contact them, but Hui Dengxiang sent a personal soldier to come. Gao Junshan didn't take the initiative to send people over, because there was already a Hui Deng Xiang over there, and Hui Deng Xiang reported to Gao Jun Mountain, Li Laochai and the Lone Ranger Wolf had 50,000 troops in Anhua, and they were self-respecting and didn't look down on people, and Hui Deng Xiang was not reused over there.

Gao Junshan is not a child, so he didn't send someone to contact Anhua, because he knew that Li Laochai and the lone wolf would not be wiped out by the Ming army in a short time, and only Li Zicheng and Zhang Xianzhong persevered to the end in history, so he didn't plan to pay too much attention to Li Laochai and the lone wolf.

In February, Ma Zhi'an, the fifth captain who ventured south to cover the transfer of the main force, miraculously returned to Huanxian. He was seriously wounded in that battle, but was rescued by an Orion, who spent three months at Orion's house to nurse his wounds, and after recovering from his injuries, he wandered in search of the team.

Seeing Ma Zhi'an alive, Gao Junshan was excited, ignoring Ma Zhi'an's ragged clothes, and hugged him tightly: "Good brother, just come back!" ”

He will not forget Ma Zhi'an's contribution to Gao Junshan, and through this incident, he has every reason to believe that Ma Zhi'an is trustworthy. After Gao Junshan entertained Ma Zhi'an with good food and clothing, he still appointed Ma Zhi'an as the captain of the fifth team, with three battalions of men and horses, and one battalion of 1,000 people.

After occupying Huanxian, the team's equipment was greatly replenished, especially the replenishment of firearms, and the arsenal of Huanxian County stored thirty tiger squat cannons and hundreds of three-eyed guns, as well as a large amount of gunpowder, Gao Junshan allocated all these equipment to Cai Zhishan.

In March, the sentry sent by Gao Junshan heard a news from Anhua that the newly appointed trilateral governor Hong Chengchou and the commander-in-chief Cao Wenzhao had defeated the rebels of Suide, Yijun, Qingjian and Mizhi in succession, and then climbed the mountains and crossed the mountains from Juzhou, took a shortcut to the Qingyang area, and formed a situation of encirclement of Anhua with Yang Jiamo, the general of the Gansu army, and Wang Xingshan, the deputy general, who had been in Anhua before.

Gao Junshan sent Sun Kewang, Feng Shuangli, Ma Jinzhong, and Ma Zhi'an to inquire about the news around Anhua, but the team did not move.

In April, Cai Zhishan's subordinate, Sun Yuanlong, finally brought Sun Yuanhua to Huanxian County with his family after a lot of hardships.

Sun Yuanhua, a dignified governor of Deng, Lai, and Erzhou, why did he come to Gaojun Mountain? It turned out that there was a reason for the incident, and the matter had to start with the Kong Youde Mutiny in Shandong.

In August last year, when Huang Taiji attacked the Daling River, Zu Dashou was trapped in the city, and when the food was exhausted, Sun Yuanhua, who was stationed in Dengzhou, was ordered to go to reinforcements.

When Sun Yuanhua sat in Dengzhou, there were more than 100,000 Liao people who avoided the war and lived in Shandong, he thought that the Liao people were available, so he reused a group of Liao generals, and now he wanted to go to help Liao Province, he ordered his subordinate Kong Youde (Liaodong people) to rush to the front line with 800 cavalry to reinforce.

However, Dengzhou Liaodong soldiers and Shandong soldiers have always been at odds, Kong Youde's 800 cavalry has both Shandong soldiers and Liaodong soldiers, when the team passed through Wuqiao, suddenly encountered heavy rain and spring snow, 800 horsemen pulled each other's skin, no one wanted to go further, stranded for a few days, the supplies could not keep up, and the soldiers drew their swords to meet each other in the torrential rain for a nest head.

The scene was chaotic, from robbery to mutiny. Kong Youde was instigated by his subordinates and simply launched a mutiny in Wuqiao, known as the "Wuqiao Mutiny" in history.

Kong Youde returned to the Shandong Peninsula, captured the cities of Linyi, Lingxian, Shanghe, and Qingcheng, and led his troops to Dengzhou. On the one hand, Sun Yuanhua urgently ordered Zhang Tao to lead the Liao soldiers out of the city to meet the enemy, and on the other hand, he urged the general soldier Sun Keda to rescue Dengzhou. What Sun Yuanhua didn't expect was that Zhang Tao and Kong Youde were buddies, and Zhang Tao's soldiers and horses immediately joined Kong Youde's ranks and defeated Zhang Ke, who came to rescue Dengzhou.

Geng Zhongming and Chen Guangfu of the Dengzhou Chinese Army are also Kong Youde's buddies, Geng Zhongming and Chen Guangfu raised fire and opened the door in response to the Dengzhou City, and Kong Youde easily occupied the whole city and proclaimed himself Marshal.

Sun Yuanhua, who was in Dengzhou at that time, was also a prisoner, and he was unwilling to be with Kong Youde, who remembered Sun Yuanhua's old kindness and released Sun Yuanhua.

After Sun Yuanhua fled, he suggested to the Ming court to appease Kong Youde, and Zhu Youzhen agreed that Sun Yuanhua should be convicted and appeased, but Wang Daochun, the governor of Shandong, advocated a quick crackdown, and he hid the edict to Kong Youde, resulting in the failure of the appeasement. Wang Daochun secretly attacked Kong Youde again, causing the mutiny to expand.

And Sun Yuanhua's political enemies, Yu Yinggui, Li Mengchen, Lu Zhenfei and others, spread rumors in the DPRK, saying that Sun Yuanhua had rebelled. Zhu Youzhen was furious and ordered the arrest of Sun Yuanhua.

When Sun Yuanhua received the news and knew that he had been framed, and was having a headache on how to escape this catastrophe, a distinguished guest came to the house - Sun Yuanlong......

Gao Junshan was overjoyed when he heard that Sun Yuanhua was coming, and he met Sun Yuanhua alone in the small living room.

Although Sun Yuanhua is a thin old man of fifty-one years old, he looks cheerful and energetic.

Gao Junshan had long heard Cai Zhishan introduce Sun Yuanhua, so the topic of meeting started with geometry. Sun Yuanhua is not only a military expert and gunpowder expert, but also has a deep study of geometry, he has written many works such as "Taixi Arithmetic", "Geometric Usage", "Geometric Body Theory", "Western Miscellaneous Works", "Western Law Divine Machine", "Jingwu Quanshu" and so on.

Gao Junshan started from the Pythagorean theorem, Sun Yuanhua was very surprised, a young man in his twenties, talking about geometry but the head of the way, the content of the discussion, from shallow to deep, from plane geometry to the category of solid geometry.

Of course, Gao Junshan still needs to grasp the measure, what he discusses is the knowledge of junior high school geometry, and most of them are discussed with him in the way of humbly seeking advice, too much publicity of his knowledge, will inevitably hurt Sun Yuanhua's self-esteem.

In such a relaxed and happy atmosphere, Gao Junshan gradually turned the topic to chemical knowledge, and then to gunpowder.

Gao Junshan took a sip of the teacup and asked Sun Yuanhua: "Dong Lao (Sun Yuanhua is called Huodong, Dong Lao is an honorific title), I heard that there is a gunpowder recipe among the people, one sulfur, two nitrate and three charcoal. I don't know if you know this recipe? ”

Sun Yuanhua smiled: "I know, I know." However, this recipe needs to be further refined, but the old decay has not found a solution to this day. ”

Gao Junshan said in a mysterious voice: "I know the chemical equation of this recipe and the principle of explosion. ”

Sun Yuanhua was excited like a child, his body swayed: "Quick, come and listen!" ”

Gao Junshan took out a pen and paper and said, "Chemical equations are to be written. Then he wrote a chemical equation on paper: 2KNO3 + S + 3C ==== K2S + N2 ↑ + 3CO2 ↑.

Sun Yuanhua shook his head and said he couldn't understand.

Gao Junshan further popularized science for him, telling him that this chemical equation expresses that the oxygen released by potassium nitrate causes charcoal and sulfur to burn violently, instantly producing a large amount of heat and nitrogen, carbon dioxide and other gases. Due to the rapid expansion of the volume, the pressure increased violently, and an explosion occurred. Due to the presence of potassium sulfide solids at the time of the explosion, there is often a lot of smoke coming out.

Sun Yuanhua nodded a little understandingly: "No wonder there will be a lot of black smoke after the gun is released." He seemed to realize something, "If you reduce the potassium content in the formula, won't the black smoke be reduced?" ”

Of course, Gao Junshan knew that this was impossible, and if gunpowder was not prepared strictly according to the formula, it could not be called gunpowder, but only flammable. However, Gao Junshan is inconvenient to explain too much to Sun Yuanhua.

Sun Yuanhua admired Gao Junshan from the bottom of his heart, so when Gao Junshan entrusted him with the task of boiling gunpowder, he gladly accepted it.

When Gao Junshan was talking with Sun Yuanhua and was still satisfied, Zhang Cong hurriedly broke in and told Gao Junshan that Hao Shaoqi led the third team of 3,000 men and horses to Anhua.
