As early as the Xia Dynasty, there were espionage activities recorded in historical records. Taikang, the third monarch of the Xia Dynasty, ignored government affairs and had fun everywhere, but was rejected by the minister Hou Yi and died in a foreign country, and set up his younger brother Zhongkang. After Zhong Kang's death, Hou Yi set up his son again. Hou Yi's cronies Han Xun instigated the slaves to kill Hou Yi and Xiang and set himself up as emperor. After Xiang's widow Shaokang grew up, he sent the minister's daughter Ai to Han Xun's son to go undercover there, and finally defeated Han Xun. Nu Ai was also China's first ever spy.

In the Spring and Autumn Period and the Warring States Period and the Qin and Han Dynasties, there were frequent wars and more spy wars. In the Spring and Autumn Period, Wu Yue competed for hegemony, and Gou Jian adopted the fourth of the literary "Nine Techniques of Cutting Wu Wu", "leaving beauties to confuse their hearts and mess with their schemes", so that Fan Li offered Xi Shi to Wu State to go undercover, and Wu State was destroyed because of his husband's indulgence in wine and desolation in national politics. During the Warring States Period, the Zhao State divided the Qin State several times, and first used Zhao Kuo to replace Lianpo, resulting in a great defeat in the Battle of Changping; then self-inflicted damage to Li Mu, and was finally destroyed. During this period, "The Art of War", "The Art of War", "The Art of War", "The Art of War" and so on were born, all of which had spy war accounts and began to be regarded as the supreme strategy.

During the Sui and Tang dynasties, tactical espionage was used in particular. Tang Taizong Li Shimin led the army alone when he was young, the most elite soldiers, combined tactical reconnaissance with the overall operation of the troops, he personally reconnoitred from time to time, and was unfortunately trapped near the Shaolin Temple, and only got out with the help of the thirteen stick monks of the Shaolin Temple. At the end of the Tang Dynasty and the Five Dynasties, spies in the appearance of various merchants and craftsmen began to appear in large numbers.

King Yun taught Yantang in public the transmission, contact, and secret writing of Yantang's espionage assassination. In particular, the secret writing is the most learned, so Zeng Gongliang's "General Essentials of the Martial Arts" is taken as an example to number 40 kinds of conventional words in the army to facilitate secret writing. This is still not enough, so he took Yuwen Xuzhong's actions and gave many examples.

When Yuwen Xuzhong was detained in Yunzhongfu, he heard that the Jin State was about to attack Sichuan, so he sent a secret envoy to inform Zhang Jun, the envoy of Xuanfu and other roads in Sichuan, Shaanxi, and attached the imperial seal given by the current emperor as a token. On both sides of the letterhead are hidden words: "Be good at upholding orthodoxy, advance and retreat." The magic is gone, and perseverance is right. Accept the advice in vain, and rather die without regrets" in which the "false advice" is the meaning of "in the void".

There is also a letter to his family in the void, which is also written in secret language: "I was coerced, but fortunately I kept it." Only one section of the period, not to live up to the society. A group of 100 people, 123 survivors today. Whoever does it can bring thousands of things to save the trouble. Yesterday, someone came from the northeast, and Taishang (referring to Song Huizong) also needed to be a medicine of the genus, and he couldn't respond to his orders, and he hated and hated very much. So Xuzhong's wife, Li Shi, played a song and asked Pan Zhiyao, who was preparing to go to Jinguo, to bring silk, silk, tea, medicine, gold and silver.

In the fourth year of Shaoxing, Yuwen Xuzhong used the talisman "Stone Shuanglin, although it was not born, the weather has been aggressive. When the heart is patient, there is no advance or retreat, the demons will descend, and my way will be victorious. If you see Zunsu, you can tell this", to Zhang Jun and the imperial court to convey information about Yelu Dashi, "Stone Shuanglin" refers to Dashi, and "Zunsu" refers to the current emperor Zhao Gou.

King Yun was already in the Imperial City Division, he had a specialization in the art industry, and his knowledge was wide, and many spy warfare techniques were explained completely and vividly, and their usefulness was appropriate. Except for Yantang, everyone has been in it all the year round, although they are no strangers to spy warfare, but listening to King Yun's lecture in public today, they are all eye-opening and beneficial.

King Yun solemnly instructed Yan Tang: "Today's events must not be revealed to the outside world. For the purpose of espionage, secrecy is the first priority, and it is related to the net worth and life of the dispatched personnel, and the success or failure of the mission must not be careless. The net worth of the family in the void was harmed by Qin Hui and other leaks. After a little hesitation, he said: "I am the former emperor and the king of Yun, the brother of the current Emperor Jianyan, and the lord and the people of the court are gaining power, and now I and Marshal Han are using troops to Jin and others without authorization, although they are in the enemy territory, it is inevitable that they will not be suspicious of the current emperor, once it is leaked, they may be suspected, I have no other, General Dong, Marshal Han, etc., have always been loyal, afraid of being discredited." So it's all the more important that I don't expose my identity here. ”

After the call, seeing that Yan Tang had entered the gang at first glance, his interest was quite high, and King Yun himself was not tired at all, and suddenly had a whim: "We have a meridian strength and a good life in Yuncheng, but since there is no Senior Brother Song Jiang, the rest of the people have dispersed, and there is no momentum in the rivers and lakes." Today, it is rare for the three of my uncle and nephew to get together, so let's go to the backyard to compare and see how my uncle's martial arts are. ”

Marshal Han couldn't help but laugh secretly, King Yun was really a martial idiot, and he just met his nephew for a while, and he actually wanted to learn martial arts. In fact, it is no wonder that King Yun practiced martial arts with Ruan Fei back then, that is, when Jingkang was in trouble, he was captured by Jin Bing with his father and brother, and he had to hide his martial arts. For a long time, it has been rare to have a competition between the same students, and today's great opportunity, how can you miss it?

Before Yan Tang could speak, he suddenly heard someone say: "Uncle Shi has a high seniority, but my senior uncle here may not be the highest." ”

King Yun felt strange in his heart, and turned his face to see that the speaker was Zhang Rong. Zhang Rong usually looks different from Yan Tang, he once led tens of thousands of troops, and he is accustomed to being a hero, looking down on thousands of troops, and has a heroic atmosphere, but at this time, he looked at King Yun, but he seemed to be smiling and slightly disdainful.

King Yun smiled and said: "We are a faction of meridian Jingong, and we have always had a nephew who disobeyed my uncle, but your ancestor was back then, and I have always been unconvinced by my uncle Qian Yi, and the two have been bickering for a lifetime." Now that it's me, it seems that Uncle Shi is not doing well, but the seniority is clearly there, and there is a saying about this? ”

Zhang Rong laughed, "Naturally, I don't dare." But if you are Uncle Yan Tang and me, you think that you have the highest seniority here, and you also have your own uncle here, so how can you talk about it? ”

King Yun was taken aback, and wondered in his heart: "Marshal Han has been brave since he was a child, his talent is extremely high, his martial arts are strong, but he learned from hundreds of schools, learned from others, especially Jing Taizu has a long fist, kung fu is mainly based on horses, mostly from the army, but it is not a famous faction, let alone this door; Li Bao is good at kung fu with his fists and feet, but he is from Shaolin, and he also learned martial arts from Aunt Shen, and practiced Yuejiaquan with Yue Fei after joining the army; Li Qiong, Dong Xian and others are not. ”

At that moment, his mind was racing, and he suddenly realized, and said: "That's Mrs. Liang, it should be the disciple of the ancestor Ruan Yan!" After the incident, Song Gaozong had lost his freedom. After discussing with the Empress Dowager Longyou, Prime Minister Zhu Shengfei decided to send Liang Hongyu to Xiuzhou, prompting Han Shizhong to quickly march to Hangzhou. During this period, the Queen Mother named Liang Hongyu as Mrs. Anguo, and Han Shizhong as the general of the imperial camp Pingkouzuo. After discussion, Zhu Shengfei told Master Miao: "Han Shizhong's failure to come immediately after hearing about the incident means that he is hesitating and hesitating. If you can send his wife to meet him and persuade him to come to you, then your strength will be greatly strengthened, and no one else will need to be afraid. Master Miao was very happy when he heard this suggestion, he thought it was a good plan, and immediately sent Liang Hongyu out of the city, Liang Hongyu went home and picked up his son, stepped on horseback, and ran to Xiuzhou day and night. After Han Shizhong learned all the circumstances, he immediately cooperated with Zhang Jun and Zhang Jun and led the army to quell the rebellion of Miao Fu and others. Song Gaozong was very happy, personally went to the gate of the palace to greet Han Shizhong and his wife, and named Han Shizhong as the envoy of the Wusheng Army, and soon worshiped as the envoy of Jiangsu and Zhejiang, and named Liang Hongyu as the wife of the protector of the country.

Li Bao said: "I haven't seen the rescue of King Qin for hundreds of miles at night and the rescue of orphans in Huining Mansion for thousands of miles, but Huang Tiandang was fortunate to lead Mrs. Liang's demeanor, and she was really outstanding in martial arts, extraordinary in courage, and as straight as a fairy." After that, Wu was impressed.

During the Song civil strife, the Jin army took the opportunity to invade. It turned out that in the winter of the third year of Song Jianyan, the Jin army was led by Wanyan Zongbi (also known as "Jin Wushu") and went straight to Jiangsu and Zhejiang. For Song Gaozong, the only way to survive was to escape. He fled first to Hangzhou, then to Mingzhou (present-day Ningbo, Zhejiang), and finally to the sea. Fortunately, the strength of the Jin army and navy was not strong, and Gao Zong barely managed to save his life. At this time, the Jin army had been alone in the south for more than five months, causing revolts from all over the Han people. Jin Wushu found that if he stayed, there was a possibility that the entire army would be annihilated, so he retreated north after a large number of captives.

At that time, Han Shizhong was serving as the envoy of western Zhejiang, and when he learned that the Jin army was retreating north, he led 8,000 naval troops to Zhenjiang in a hurry to prepare for an interception. Although the Jin army claimed to have 100,000 troops, its true strength may not have reached such a staggering number. In contrast, however, the Song army led by Han Shizhong had already experienced some setbacks when the Jin army moved south. In addition, the traditional art of war has long been about the rule of "return to the army do not stop", that is, do not stop the army on the way home, because the soldier's longing for hometown in this situation will stimulate combat effectiveness beyond the convention. On the whole, judging from the surface of troops, morale and combat effectiveness, Han Shizhong is obviously inferior to the Jin army. Jin Wushu, the commander of the Jin army, probably also thought that Han Shizhong was seeking his own death, so he issued a war letter to Han and agreed on a specific date for the war. Han Shizhong agreed to the challenge. On the appointed day, the Jin army began to cross the river on the north bank of the Yangtze River, while Han Shizhong led the army to intercept on the river. The two sides fought fiercely on the river, and the Jin army attacked again and again, but they were successfully repelled by the Song army led by Han Shizhong. And Liang Hongyu personally beat the drum in the rain of arrows, boosting the morale of the Song army. In the end, the Jin army could not successfully cross the Yangtze River, and the Song army won another victory, and the morale of the Song army increased greatly for a while.

Mrs. Liang personally beat the drums to help the battle, and the morale of the Song army doubled, defeating the Jin Zhizhou division in one fell swoop. Jin Wushu hurriedly sailed into the backwater port of Huang Tiandang in the northeast of Jiankang, and then adopted the advice of the local villagers to dig the old road of the Lao Stork River, and rushed out of Huang Tiandang the next day, so he had to flee for his life.

This battle made Mrs. Liang even more famous in the world, but it was the worst defeat in Jin Wushu's life.

King Yun said: "I didn't see the battle of Huang Tiandang, but I heard a lot. But Mrs. Liang would save the orphans in Ningfu for thousands of miles, and after fighting Yan Liang and several other warriors of the Jin Kingdom, I saw it on the spot. Although those samurai are not the best in the world, they are all good players. I saved my son Shi Yu in the void, and I was lucky to get rid of it by fighting desperately. Mrs. Liang saved her granddaughter, who was five or six years old, and was able to break through with her whole body, and her martial arts were even more remarkable. ”

After that, he looked at Fan Yantang and said, "Those Jin Kingdom warriors, led by Wanyan Liang, the king of Hailing, are all children of the royal family, but they use the meridians of our sect. I think that Patriarch Wang made a total of two acupoint bronze figures and put them in the Taiyi Bureau for use, one of which was unfortunately taken away by the Jin people during the Jingkang disaster. Jin Ren took it back to study it, and with the guidance of a former student of the Taiyi Bureau, he finally cracked the secret. Among those people, Hailing King Wanyan Liang has the highest martial arts, only slightly weaker than me, and the others are also first-class masters. If you encounter it in the future, be careful. At that time, Mrs. Liang and I just happened to save people, and when we started, we went out separately, and we didn't care about Mrs. Liang's martial arts at all, but the opponents were all martial arts. I couldn't help but shake my head and smile bitterly.

King Yun raised his face and swept everyone's eyes, and shouted, "Go see my uncle!" The crowd couldn't help but laugh. Refer to the humble book "The Legend of Xin Qiji"
