Yang Shi, the leader of the defenders of the water storage embankment in the mountains behind Gucheng, claimed to be the general of the Yang family of the famous family of the Northern Song Dynasty, and the weapon used was said to be the ancestral broadsword, in fact, Yang Shi was only a deputy general in the army of the Cuizhu Kingdom, and his martial arts cultivation was not very good, but this person was flamboyant, good at flattery, and could look at the faces of the superior leaders. Prime Minister Miao Cheng gave him such a simple errand to do, mainly because he found that he really did not show any talent in the process of fighting with the enemy, and after a long period of investigation, Prime Minister Miao Cheng felt a little uneasy about Vice General Yang Shi's loyalty and personality. Once, after the victory of the Cuizhu Kingdom, a soldier reported to Prime Minister Miao that Yang Shi had secretly bullied the family members of the enemy generals after the war.

In fact, the person who knows Yang Shi best, the deputy general of the Cuizhu Kingdom, is the scholar king, it turns out that the scholar king and Yang Shi were both in the same nunnery on the top of Yunmeng Mountain on the border of Cuizhu and Niuling when they were still young, and they both worshiped an old man to learn the art of war. At that time, there was no dispute between Cuizhu and Niuling, and the two countries lived in friendship and harmony, because the king of the neighboring country of Niu was content with the status quo at that time, and there was no quarrel with the world, and the country was governed in the spirit of not seeking merit, but seeking no fault. Therefore, the two countries often come to the future normally, and the relationship is harmonious. At that time, the king of Niuling was the father of the scholar king, in order to achieve the emphasis on the training of the scholar king, so he ordered him to go to Yunmeng Mountain to worship the old Taoist as a teacher and learn the way of governing the country and using soldiers. At that time, Yang Shi's father, in line with the purpose of carrying forward the spirit of the Yang family's historical tradition, repeatedly came to the door to plead, and finally moved the old Taoist with sincerity, and asked him to send Yang Shi to the nunnery to consult and study with the scholar king. It's just that everyone's level of effort is different, and there are differences in learning and acceptance, so later, after careful consultation and study, the scholar king was able to govern the country and lead the army into battle. And Yang Shi just returned to China after giving up halfway through his studies and became a deputy general in the barracks.

Therefore, when the scholar king heard that the leader of the embankment defenders was Yang Shi, the scholar king suddenly felt that he had almost a solution to the current dangerous situation, and the solution was to use their understanding of Yang Shi and his former brother-in-law relationship with Yang Shi to plot against Yang Shi, and do the opposite, turning the disadvantage into advantage, so as to obtain a breakthrough from the trapped siege of Gucheng and avoid suffering a catastrophe.

The scholar king clearly understands that Yang Shi's character is not ordinarily bad, and it can be said that he definitely has the temperament of forgetting his righteousness and valuing lust over friends. The scholar king remembered very clearly that in fact, Yang Shi was kicked out of the temple by the master when he did not complete his studies, because the master found that Yang Shi always liked to go out quietly in the middle of the night, and later after the master's secret observation, it turned out that Yang Shi This guy took this opportunity to sneak into a nunnery on a nearby mountain peak when the master sent him into the mountain to collect medicine, and hooked up with a nun who had not finished the six roots and became a nun. The master was very angry, so he expelled him from the mountain gate.

According to Yang Shi's temperament, the scholar king knew that as long as he took some feasible ways to seduce him, he would definitely be able to turn him against him. Without further ado, the scholar king immediately wrote a letter in his hand, instructing Ye Changfei to jump out of the encirclement of Prime Minister Miao as soon as possible, rush to the back mountain of Gucheng, and find a way to send the scholar's handwritten letter to Yang Shi.

The key is how to give the king's handwritten letter to Yang Shi in the case of concealing people's eyes and ears, the scholar king did not dare to act rashly, he climbed on a green pine on the edge of the cliff, used dense branches as a cover, observed the movement of the embankment defenders, especially to grasp Yang Shi's whereabouts, to see if he could find the right opportunity, contact him, and send a handwritten letter. After almost a whole day of observation, Ye Changfei found that Yang Shi led several followers to patrol the embankment three times a day, and did not go out at any other time. The task was not completed, and he could not return to Valley City at night, so he could only eat the dry food he carried with him, and then continued to lie on the branch of the green pine, observing the situation at night to see if he could find an opportunity.

After the night was filled for a long time, the defenders of the back mountain all turned off the lights and rested, suddenly, Ye Chang Fei found that Yang Shi sneaked out of the camp, and walked straight to the jungle of the mountain col, Ye Chang Fei unconsciously slipped down from the green pine, followed Yang Shi quietly behind, Yang Shi passed through the jungle, and finally came to a mountain farmhouse on the mountainside, when Yang Shi arrived, he deliberately coughed a few times, maybe this was a code, and then, the door of the mountain farmer's house opened, Ye Chang Fei found that the door was opened by a more delicate young woman. Ye Changfei suddenly understood that while Yang Shi was performing official duties in the barracks, he couldn't change his old problems, and he ran out late at night and was happy.

Ye Changfei thought that this was a great opportunity to complete the task assigned by the king, and he calculated that Yang Shi and the young woman should be happy when they were happy, he kicked open the door of the mountain farmhouse, and the young woman's two sons who were awakened in their sleep were frightened and screamed, this woman may not have a man, except for the two children who were scared and cried, only Yang Shi and the woman, who were frightened by this sudden change, and the woman both opened their eyes wide. Ye Changfei is ready to take advantage of the fact that Yang Shi was found to be ugly and grasped the weakness, to do this matter. Ye Changfei asked to have a confidential interview with Yang Shi, Yang Shi's brain was almost blank on this occasion, he quickly nodded and agreed, and then put on his clothes and left his wife and sat down in a side room of the woman's house with Ye Changfei. After the woman was dressed, in order to show that she would please Ye Chang Fei and let him not expose her ugly things to the public, she then went into the side room and made tea for them, Ye Chang Fei waved her hand impatiently and ordered the woman to go out quickly, and then closed the door tightly.

Ye Changfei conveyed to Yang Shi the handwritten letter of the scholar king. The scholar king said bluntly in the handwriting, instigating Yang Shi to see the relationship between the two who were brothers, in her current critical moment, can open the net, let him have a way to live, the scholar king also made it clear, if Yang Shi can help him, his kingdom can give him cash money and beauty, and even after the matter is completed, Yang Shi simply defected to Niuling Kingdom, and the scholar king said that he can ensure that he can sit on a high-ranking official and ride a horse. Yang Shi, a villain with a lust for profit, saw these promises of the scholar king, and then thought about his situation in the Cuizhu Kingdom, and agreed to all of them without the slightest hesitation, and proposed what to do next, he listened to the instructions of the scholar king, and proposed that there should be a channel for transmitting information between each other. The task of flying at night was completed, and I couldn't help but feel a little happy in my heart. He motioned for Yang Shi to hurry up and continue to complete his unfinished business, so he slipped away and went straight to Gucheng.

As the temperature rises, the snow melts faster and faster, and the embankment behind Gucheng is full of snow water. Prime Minister Miao Cheng felt that since the water rushed to Gucheng and the conditions for drowning the enemy army had been formed, it was necessary to take action, so as not to have too many dreams at night. Prime Minister Miao sent someone to convey an order to Yang Shi, asking him to completely destroy the living force of the coalition led by King Shusheng at the expense of the people of Gucheng in the middle of the night, when the royal army besieging Gucheng quietly withdrew, while the enemy army in Gucheng was sleeping.

Yang Shi hurriedly passed the news to the scholar king through the re-arrival of Ye Changfei. The scholar king knew that the time had come to resurrect the dead, and the scholar king understood that when Prime Minister Miao planned to flood Gucheng, the army he led had to quietly evacuate when the scholar kings could not notice it in order to avoid being flooded. This is only possible in the dead of night. Therefore, the scholar king still asked Ye Changfei to convey the specific method to Yang Shi. Because the army was fighting and the people were innocent, the scholar king secretly arranged for the people in the city to prepare for the evacuation together, so as not to cause flooding.

The scholar king stayed awake for several nights, and in the middle of the night two days later, he found that Miao Cheng's army guarding outside Gucheng had quietly withdrawn to the river valley a few kilometers away from Gucheng. King Shusheng told Yang Shi that he must do what Prime Minister Miao had ordered, and after the withdrawal of Prime Minister Miao's army was over, at night, Yang Shi must break the embankment and release water, otherwise Prime Minister Miao did not hear the sound of the water washing, found something strange, and turned back to surround it, at this time, the coalition army was evacuating, the city gate was wide open, and Prime Minister Miao's army took the opportunity to rush into the city, then only the same army was annihilated. Therefore, it is necessary to have the sound of the embankment breaking and flooding as a cover, so that the scholar king can achieve the purpose of evacuation. Therefore, the scholar king instructed Yang Shi to cut down the trees on both sides of the col in advance in order to give them enough time to evacuate, and put them in the embankment where water is stored. When enough time had been given to evacuate, the water became stronger, and eventually the entire city was flooded.

After Prime Minister Miao evacuated, when King Scholar heard the sound of water bursting on the top of the mountain, he knew that at this time, Prime Minister Miao Cheng concluded that his plan was about to succeed, and he was already in a state of peace of mind after the withdrawal was over. King Scholar immediately ordered the soldiers and civilians in the city to evacuate immediately. Taking advantage of the night, the people in the city fled to the heights of Yunmeng Mountain in order to avoid the disaster of flooding. King Shusheng led the allied forces of the two countries, explaining that he could not raise torches, there could be no shouting, and he quietly took advantage of the night to evacuate along Yunmeng Mountain to safety. After calculating that the scholar king had finished evacuating, Yang Shi instructed the soldiers to break the embankment, and after the water washed away the trees that had been blocked, he poured down. After a while, the entire valley city was an ocean.
