Because the king of Zhou gave Zhang Xun an errand to compile historical books, Zhang Xun smoothly entered the place where the royal archives were stored and looked up the records of the case that year. It took Zhang Xun a full morning to come out, because he also read all the records of the royal archives in the first and second half of that year.

It turned out that in June of the year before Bai Yiqiang was imprisoned, the former king wanted to follow the example of the ancient Emperor Yu to control the water, and invested a huge amount of money to comprehensively control the floods of the Yellow River. So Bai Yiqiang was appointed by the former king as a messenger with the official position of a squire in the Ministry of Works, and was fully responsible for the management of the Yellow River. Bai Yiqiang knows that for the Yellow River, the key to water control is to control desertification. Clearing the river silt and sediment, keeping the Yellow River green, and avoiding soil erosion were the strategies developed by Bai Yiqiang at that time. At the beginning, I went to Sanmenxia, where I tried to verify the feasibility of the plan, which lasted for three months, proving that the comprehensive treatment plan of "cleaning up siltation and maintaining water and soil" was feasible and effective. Bai Yiqiang returned to Luoyang and reported the results to the former king. Seeing that the results had been achieved, Bai Yiqiang was asked to immediately expand the scope, and it was necessary to find out the water and soil conservation situation and the siltation situation in each section of the Yellow River by the end of the year, and formulate a specific treatment plan. In this way, Bai Yiqiang just arrived in Luoyang and turned around and went out of Luoyang to Jiaozuo, Xinxiang, Kaifeng, Puyang and all the counties along the Yellow River under the jurisdiction of these four prefectures. After returning to Luoyang, he formulated a complete plan for the control of the Yellow River in Baifu. The plan was very detailed and took 15 days to develop. However, in the process of formulating this plan, it was found that there was a key point missing, that is, Zheng County. The reason why Bai Yiqiang ignored Zheng County before was because it was a fief given to the younger brother by the previous king, and he only paid taxes to the central government, and the specific affairs were managed by the younger brother himself, and the central government generally did not interfere, otherwise it would not be called a fief. As for the survey of the Luoyang section of the Yellow River, Bai Yiqiang handed over the responsibility of his master, and he was still relieved, so this plan was only lacking in Zheng County. Bai Yiqiang is a person who strives for perfection, not to mention that the position of Zheng County is very important.

On the second day, Bai Yiqiang met with the queen and made a detailed report with the completed comprehensive management plan for the Yellow River. The most satisfying thing about this plan is that it is divided into sections and responsible for the implementation of people. The whole plan is divided into six areas, Sanmenxia area (although it is a pilot, but the intensity should be increased. Luoyang Area, Jiaozuo Area, Xinxiang Area, Kaifeng Area, Puyang Area. The area is divided by the government, and the prefect is responsible for the general judgment and supervision. Because Luoyang is the capital, the area is in charge of the Ministry of Industry. The sections are divided by counties, and the prefectural orders are responsible, and the master registers assist, and supervise each other. In short, this plan emphasizes that it should be handled according to the rules, the responsibility will be assigned to the person, the meritorious will be rewarded, and the fault will be punished. Finally, Bai Yiqiang took out a schematic map (simple map) along the Yellow River and said, "Your Majesty, please see, this plan is missing a key point, Zheng County, because the geographical location of Zheng County is extremely special, if Zheng County is not governed at this point, it is estimated that the effect of the entire plan will be reduced by at least thirty percent." After the minister, I want to go to Zheng County to investigate, please ask Your Majesty for permission. The first king said: "Bai Aiqing, no one knows about the situation, and we will discuss it after the year." Go down!"

In the first early court after the Lantern Festival, the former king asked his eunuch Li Xing to read out the plan for the comprehensive management of the Yellow River by Bai Yiqiang, a squire of the Ministry of Works. After Li Xing finished reading it, the first king asked the hundred officials to discuss. Baiguan is not a fool, this is obviously the first king decided to implement it according to this, so what else to discuss and agree to carry it out. After the hundred officials expressed their attitude, the king asked Li Xing to send people to distribute the plan to all prefectures and counties for implementation. The first king asked again, "Ladies and gentlemen, do you have something to play?" Seeing that no one was playing, he said, "Bai Aiqing stays, and the rest of the people retreat." After the hundred officials saluted and retreated, the first king handed Bai Yiqiang a letter and said: "Bai Aiqing, this is a handwritten letter from the widow to Brother Wang, and the survey and governance of Zheng County will be handed over to you." ”

After Bai Yiqiang left the palace, he took a few entourages and immediately rushed to Zheng County, and immediately went to Zheng Gongfu after arriving in Zheng County (called by fiefdom, sealed in Zheng County, so called Zheng Gong. After seeing Zheng Gong, he handed the letter of the former king to Zheng Gong and said, "Zheng Gong, this is a personal letter written to you by Your Majesty. Bai Yiqiang, a servant of the Ministry of Ministers, came to Zheng Gong's fiefdom this time to investigate the river channel and soil and water conservation conditions and then control it, so as to avoid flooding of the Yellow River in the territory to the greatest extent. I also hope to get the support of Zheng Gong. Zheng Gong said: "The situation is known to this father, and this guild orders the personnel belonging to the fief to cooperate with you." ”

At the beginning, the survey phase was relatively smooth, and it was completed in a month and a half. After calculating the cost of treatment in Zheng County, he drafted a report and asked the two retinues to send them to Luoyang to hand over to the first king. Bai Yiqiang waited for two months, but what he was waiting for was the shackles of the Criminal Department to escort him to the capital Luoyang, and later he learned that Zheng Gong used the governance money to raise an army to rebel, and committed suicide after failure. The first king sent people to complete the river management in Zheng County.

The above is all the content of the major cases that Zhang Xun learned about through Bai Yiqiang's narration in the prison and consulting the royal archives. Zhang Xun knew that he had to go to Zheng County.

Back at Zhang's Mansion, Zhang Xun asked Bihe and Yuchan to call Bai Yulian and Bai Wen. Zhang Xun was going to take Bihe, Yuchan, Bai Yulian, and Bai Wen to Zheng County this time. Xinlan and Wenxin take care of Zhang Xing, Zhang Qianwen, Zhang Xiuya, and Zhang Ming at home. The reason why the two masters and servants of the Bai family were allowed to go over was because of the identities of the two, Bai Yiqiang stayed in Zheng County for a long time, and the local people may have insiders, and Bai Yiqiang was meritorious in dealing with the floods back then, maybe these insiders will be grateful to him and willing to tell his descendants about the situation;

After Bihe and Yuchan brought back the master and servant of the Bai family, Zhang Xun told them about going to Zheng County, and the four of them were naturally willing to go. Zhang Xun asked the master and servant of the Bai family: "Niece Yulian, Bai Wen, can you two ride horses?" Zhang Xun considered that it was better to avoid people's eyes and ears, especially not to let Liang Xiangguo notice, so he said: "Bihe, Yuchan, you must pay attention to see if anyone is following you on the road." We left Luoyang at dusk and rushed to Zheng County. ”

At dusk, after Zhang Xun and his entourage of five people rode out of the Luoyang City Gate, they stopped and stopped, not at all like they were going to travel far. It wasn't until I confirmed that no one was following me that I hurried all the way to Zheng County, and after eating something casually, I found an inn to stay. Zhang Xun thought in the room, how should his group find clues? He and Bai Wen went directly to the county magistrate of Zheng County, and on the pretext of compiling historical books, they wanted to investigate the topography and landforms along the Yellow River and directly investigate them publicly. Bihe, Yuchan, and Bai Yulian paid a secret visit, pretending to come from other countries to find relatives, and there were two objects to find relatives, one was Xue Xiaoshan, the housekeeper of Zheng Gong's Mansion back then, and the other was Ding Dajun, who helped Zheng Gong purchase weapons, and it was said that he was a small leader of bandits. Both men had disappeared at the time, either by their mouths and by their bodies or in hiding. Bihe's skills are better than Yuchan, so she let Bihe and Bai Yulian find Ding's army, and Yuchan looks for Xue Xiaoshan alone.

Early in the morning of the second day, as soon as Zhang Xun explained the plan, the three groups acted separately. Zhang Xun and Bai Wen found the county magistrate of Zheng County, and the magistrate agreed as soon as he heard that the matter was not troublesome. Zhang Xun and Bai Wen went to the construction site of the year to check, Bihe and Bai Yulian were in the east of the city, and Yuchan was alone in the west of the city, pretending to be looking for relatives and going door to door, and everyone who met people over 30 years old asked. The first three days yielded nothing, and on the fourth day, an old beggar found Zhang Xun and asked directly: "Are you here to investigate the incident back then?" I know the whereabouts of those two people. Zhang Xun knew that the old beggar was asking for money, so he asked how much, and the beggar stretched out a palm. Zhang Xun said: "Five hundred taels is fair. The old beggar said: "I see that you are also a person who has seen the world, do you know that the beggar gang has never been less than 5,000 taels?" Zhang Xun thought to himself, "It seems that no matter which dynasty or generation, the beggar gang is terrible to death!" Zhang Xun said: "I can give 10,000, but only 2,000 first, and then 8,000 after verification." The old beggar took the two thousand taels of silver ticket and said, "Those two people will hide, on the ancestral mountain outside the city, they have been falling grass on the peak of enlightenment, and founded a cottage called Juyitang." The 8,000 taels of silver tickets, you can go to the Yellow Emperor Temple after finishing your errands and press them under the plates on the offering table. With that, he left.

Zhang Xun and Bai Wen returned to the inn to rest, and in the evening, Bihe, Bai Yulian and Yuchan came back one after another. As soon as Zhang Xun said the information mentioned by the old beggar, he said to the second daughter of Bihe Yuchan: "Bihe, Yuchan, you two went to the Enlightenment Peak late at night to explore the reality of the Juyi Hall. Without alarming the two of them, grab a little minion and ask, I and Yulian's niece and Bai Wen will meet at the bottom of the mountain tomorrow morning and under the peak of enlightenment tomorrow morning. ”

At night, Bihe and Yuchan's two daughters, dressed in black and masked, went to the Juyi Hall. The second daughter's light skills were already very good, and the night patrol in the Juyi Hall was also perfunctory, so she naturally entered the Juyi Hall smoothly. Bihe and Yuchan saw that this cottage was not small, so they decided to explore separately, and after finishing the incident, they gathered in a cave that the two of them had discovered earlier. Soon Bihe noticed a small minion under a tree who seemed to have drunk too much, and fell asleep on the stone table. Bihe decided to catch this guy and ask, so she went over and ordered the holes of that guy, carried them to the cave, and threw them on the ground. After solving this guy's acupoint, this guy may have drunk too much and slept very dead. Bihe didn't bother to look for water to wake up this guy, and when she raised her hand, she slapped her face with two heavy slaps, and the guy woke up in pain. Bi He saw that this guy woke up, and said: "This woman asks you, the two heads of your cottage are surnamed Xue and Ding, and what is your identity in this cottage?" Just cook and don't do anything else. The heroine spares her life!" Bihe said: "This heroine is just asking for a question. At this time, Yuchan returned to the cave alone, and it seemed that no one was caught. Yuchan saw Bihe scratching a "tongue" and asked, "Sister Bihe, did you ask anything?" Bihe replied: "It is determined that the two masters of this cottage are indeed the people we are looking for, and this guy is a cook." Yuchan said: "I figured out the terrain of the cottage, and that's enough." Click on this guy's sleeping hole, put it back under the tree, and go down to the peak!"
