The Ji clan's civil strife ended with Yang Hu's complete victory. Yang Hu served as the elder of the Ji family and Sima, and since then he has officially controlled the military and political power of the Ji Sun clan and even the Lu State, and has become the first person in charge of the vassal states - in the past, any order issued by the Lu Hou had to be approved by the Ji family, and now any decision made by the Ji family must be approved by Yang Hu.

Regarding this incident, the people of Lu were extremely uneasy while watching Ji Sun's jokes. Yang Hu set a rather dangerous precedent, and his "success" stimulated many ambitious retainers like him to make them ready to move; At the same time, it also made the doctors begin to be suspicious of their retainers.

The social contradiction spreads from the contradiction between the monarch and the minister in the middle and upper strata of the society to the contradiction between the master and the servant in the middle and lower strata of the society; Mutual distrust between master and servant exacerbates social unrest and puts everyone at risk. Finally, the full-scale spread of contradictions has also increased the uncertainty of the country's domestic and foreign policies, bringing great unknown risks to national security.

In the first month of the sixth year of Lu Dinggong, Zheng Guo took advantage of the outbreak of war in Wu and Chu to destroy Xu State. The envoys of the Jin State hurriedly came to Qufu and asked the Lu State to send troops to punish Zheng Guo for the crime of sabotaging the "Song Alliance".

Yang Hu was overjoyed, and he saw this task as a precious opportunity for him to win the support of the Jin people.

As mentioned earlier, Zheng Lu had a war before the Spring and Autumn Period (Lu Yin Gong was also captured by Zheng Zhuang before he ascended the throne); After the Spring and Autumn Period for more than 200 years, the two countries clashed from time to time, and Zheng Guo's record was obviously in an advantageous position.

For a while, the state of Lu was so afraid of the state of Zheng that the Lu army did not dare to cross the border of the state of Zheng alone when they participated in the alliance meeting (the year when the Battle of Yanling broke out in Jin and Chu)! Lu Dafu Gongsun Yingqi had to ask the Jin people to provide protection for the Lu army to cross the border. As a result, the people of Lu were not less laughed at by the princes of the world. They said that they would not greet the Lu people in the next operation, otherwise once the war against the Zheng State began, the Jin army would also divide troops to protect the Lu army.

Therefore, Lu Jun has never been able to raise his head in the face of Zheng Guo, and Zheng Guoren has always shown a scornful attitude towards Lu Jun. Now, Yanghu is eager to wash away the shame with the blood of Zheng Guoren and build an epoch-making monument.

Yang Hu ran into the national storage room for a few days for an unprecedented time, read a large number of classics that recorded Zheng **'s actions, and asked a doctor who specialized in the study of Zheng Guo's problems for many questions. He found that the commanders of the Zheng State were particularly adventurous, belligerent and greedy for merit, and they always used all means to maximize the tactical effect (while the tactics of the Lu State were always inflexible). Yang Hu decided to return the favor with his own way, and he was full of confidence that the Lu army would definitely win this time.

In February, Lu Dinggong, Ji Huanzi, Meng Yizi, and Yang Hu Shuaishi went on an expedition, and Shusun Prefecture defended the country. The actual commander of the war against Zheng was Yang Hu, and everyone else was a tablet.

The Lu army aimed at Kuangyi (near present-day Changyuan, Henan) in the northeastern part of Zheng State. Kuangyi is located on the main trade road between Zheng and Wei, the city is large and rich, the wall is high and the pool is deep.

In order not to give the Zheng people a chance to prepare, Yang Hu led his army straight through the land of Wei Guo without borrowing from Wei Guo.

To the southeast of Kuangyi is a hilly area with dense vegetation, and Yang Hu "invited" Meng Yizi to lead the army to hide behind the hills, and then personally led the Ji army to attack the city gate.

On the one hand, Dr. Kuangyi organized defense, and on the other hand, he sent people to Xinzheng to report the emergency. Zheng Guo's consul at that time was a scy, and he and Yaqing Handa each led an army to the rescue.

Yang Hu ordered a halt to the siege the day before the arrival of reinforcements. He ordered his subordinates Ran Hui and Ran Meng brothers to retreat overnight with an elite army, and set up an ambush in a dangerous place on the border between Zheng and Wei.

Si Yu and Handa led reinforcements to the western suburbs of Kuangyi, and several commanders boarded the city to look in the direction of the Lu army camp and saw the number of enemy troops

The amount is less than 60% of your own. Si Xiao couldn't help but hum: "Xiao Luhou has forgotten the history of being beaten again, and he must be educated and educated well tomorrow." ”

Handa said: "Yes, there have been no slaves of the Lu Kingdom in my mining for a long time, and I must catch a few more tomorrow." ”

But the next morning, Zheng Guoren was surprised to find that Lu Jun had sneaked away the night before. The retreat further stimulated the battle**, and he immediately led his entire army in pursuit of the enemy.

When the sun was in the west, Zheng Jun turned a hill. Si Xiao spotted the Lu army resting not far ahead, and also saw the military flag fluttering on the Lu Dinggong chariot (but the Lu army was not so much resting as luring the Zheng army to attack, because the Zheng army could see the Lu army there whenever it arrived).

Overjoyed, he was eager to attack, but Handa persuaded him, "No." The sergeants had run dozens of miles in one go, and now they were very tired, so it was better to stop here and observe the enemy's movements. The Lu army will definitely not continue to advance, and we will also regain our strength here and attack again at night. ”

He said: "Not far ahead, we will reach the border of the country, and once the Lu army crosses the border, we will not be able to do anything." ”

Handa said: "Isn't it also a good thing to avoid the tyranny of the three armies and our army to win without a fight?" ”

Si Xiao said disdainfully: "No wonder there are no slaves of the Lu Kingdom in your minions, it turns out that your slaves are all bought." He ordered him to rest in place for half an hour, and then he attacked the enemy.

The Lu army was frightened by the sudden attack, the commander knocked Jin Duo like crazy, the sergeants scurried around in a panic, and Lu Dinggong fled to the border in a chaotic situation.

The sirling shouted: "The one who captures Lu Hou will be rewarded with a doctor!" The one who captures Ji Sunsi will be rewarded with the doctor! Those who get a doctor will be rewarded with a county! Those who get a taxi enjoy a hundred acres of land! ”

The Zheng ** soldiers forgot the fatigue on their bodies, and suddenly felt as light as a swallow, and they rushed towards the Lu army with high spirits and scrambling. The two sides chased me and fled, and successively entered the ambush circle set up by the Ran brothers. Yang Hu beat the drum vigorously (this was the signal to attack), and the Lu army ambushed in all directions, rushing towards the Zheng army in a swarm.

In the face of danger, he immediately ordered the pursuit to be halted and the overwhelmed army regrouped into a defensive formation.

The Lu army did cause some losses and confusion to the enemy when it launched a surprise attack, but because it was still inferior in numbers (Zheng had two corps and part of Kuangyi's local army, and Lu only had one and a half armies), Zheng quickly stabilized its position.

Yang Hu summoned Ran Meng and said, "Bring your subordinates to follow me, I want to catch that old thief!" ”

Zheng Jun fought and retreated, slowly withdrawing from the pass. Yang Hu rushed out of the pass with the death squad, galloped along the side of Zheng Jun, and rushed straight to the squire. He was concentrating on directing the battle, and suddenly saw Yang Hu running towards him with a hideous face, and he couldn't help but be shocked. Although there were many sergeants around him, due to the suddenness of the incident, the sergeants did not have time to assemble to resist the attack. He had to turn around and flee, but Yang Hu killed his horse with an arrow, and he had to abandon the car and flee, calling for soldiers to block the enemy as he fled.
