Wei Wengong no longer refused, he ordered the army to be gathered and prepared for the expedition. The guards set out from Chuqiu and marched towards Zilou (west of the garden). Along the way, a large number of family armed forces spontaneously rushed to join the ranks, and the arrival of new troops greatly boosted the morale of the army. Wei Wengong incorporated them into the auxiliary army, and the number of auxiliary troops quickly exceeded the regular army.

When the guards reached Zilou, the enemy also reached the outskirts of the garden. The Xing division was stationed in the east of the city, while the Di army camped outside the south and north gates. Although the Di army was outnumbered, it was cobbled together by many tribal forces.

The lack of unified and effective command was the greatest weakness of the Di army, and this weakness was magnified by the fall of night and the fatigue of the soldiers, so Wei Wengong decided to launch a night attack on the Di camp.

The target chosen by the guards was the Di army outside the north gate. Di Ying's back was to the Pu Shui, which flowed eastward, and the river would inflict additional damage on the enemy, magnifying the results of the sneak attack.

The second watch is the time when human beings are most sleepy and need sleep. But the patriots were so excited that they couldn't sleep, and a large number of auxiliary troops, led by a small number of regular troops, quietly touched the west side of the camp. The fortifications on this side were not yet finished: the trenches were wide but not deep; Due to the lack of trees in the surrounding area, the fence was not built. The enemy fell asleep, and the Night Watchmen dozed off with their weapons.

As soon as the guards rushed up and broke into the camp, the dogs in the camp suddenly barked wildly, and the enemy was immediately terrified. The guards were merciless in the slaughter, and the fierce drumming and shouting outside the camp added to the chaos in the camp.

The attackers tried their best to drive the enemy to the north of the river, and the Di people, confused in panic and darkness, stepped into the river one after another; It was only because Pushui was in the dry period at that time that too many people were not drowned.

At the same time as the guards launched a night attack, the guards of the city poured into the city walls, carrying torches and striking all the objects that could be knocked to scare the enemy. The allies of the Di army, who were attacked by the sneak attack, could not figure out the situation, so they had to huddle in the camp to observe, and did not dare to go out to rescue their comrades.

The battle ended when the East dawned. The Patriots had great successes and obtained a large amount of booty; As they retreated, they set another fire and destroyed everything they could.

The survivors fled to the barracks of Xing Guoren and their companions, many of whom suffered terrible wounds; The most important thing is that the spirit is greatly stimulated, and the will is destroyed.

The survivors described the Patriots as demons who had been released from hell by the Grim Reaper, saying that even the Chidi and the legendary Donghu people would not be so cruel as to want to destroy everything. They also said that as long as Wei Wengong was alive for a day, they would never step into the defense of the country again, and no one would want to compete with the devil's messenger again.

The victorious guard moved the camp several miles forward, and anyone could feel the fierce and aggressive momentum of the guards.

The atmosphere of fear soon spread throughout the enemy camp. The Di people could not bear the tremendous mental pressure, and retreated that night; Xing's army could not be supported alone, and the army was withdrawn and returned to China the next day.

Although Wei and Xing did not fight head-to-head this time, Wei Wengong had listed Xing Guo as the number one enemy; As for the Yidi tribes, the Patriots no longer disdained to regard them as opponents.

In the autumn of the 19th year of the reign of Emperor Lu (641 BC), Wei Guo retaliated against Xing Guo for the Battle of Supu.

This year, the people of the country have been plagued by drought since the beginning of the summer, and people have seen that the crops have dried up in a large area and the grain harvest is facing the dilemma of failure, but the sky is still shining brightly, and there is not a trace of clouds. The guards divined "whether the sacrifice of mountains and rivers can be used to obtain rain from heaven", but the results of the divination showed that they were unlucky.

Doctor Ning Yu said: "When the Western Zhou Dynasty suffered a famine, Taishi Jiang Shang proposed to attack the Great Shang, and King Wu got a good year after defeating the Shang. Now the Xing Kingdom has no way but the wind and rain are smooth, the princes have no leader, and no one punishes the evil. Could it be that God wants to defend the country and crusade against Xing to maintain the way of heaven? ”

The guards also carried out divination for Vaxing, and the result really showed the image of good luck. Wei Wengong ordered the army to be recruited, and after Wei Guo left the army, it rained heavily from the sky, and although the land was dry, it was not a disaster. Taking advantage of the auspicious signs shown by the heavens, the morale of the guards soared, and they conquered the two great cities of Xingguo in a row.

In the twentieth year of the reign of Lu Xugong (640 BC), the situation in China underwent many changes (these changes are described in detail later), one of which was that Qi Xiaogong changed his strategy towards Xing and Wei and instead supported Xing to attack Weiguo.

It turned out that the fourth prince of Qi was in exile one day, and Qi Xiaogong couldn't sleep and eat for a day. In fact, the ambitions of the sons have disappeared, and they recall the glorious days in the Qi State back then, so they send messages to Xiaogong through various channels, hoping to obtain his forgiveness and allow them to return to China. But Qi Xiaogong's heart is too heavy, he has always been jealous of his brothers' disobedience, and when he saw the letters from his brothers bowing their heads and begging for mercy, he finally breathed a bad breath, and felt particularly relieved; But he felt that the revenge was not yet fun, so he never let go.

Gao Zhuangzi persuaded: "The sons fled from all directions, and they always became the heart disease of the princes; The worries of the princes are also the worries of the office, and the worries of the ministers are the worries of the people. So why not call them back? If there is no loss, the fourth prince will never commit a crime. Now that the culprit has been ambushed and the country is stable, the fourth prince is still wandering abroad and making ends meet.

"They have regretted it, but they have not been pardoned by the monarch, and resentment will surely arise in their hearts. Brotherly grudges are unfortunate for any country, and they will bring disadvantages to the office. The state of Qi cannot fight against the enemy while also guarding against the son-in-law of his own family; If the enemy was recruited by the sons, it would be even more unacceptable.

"So, please forgive them! When the sons return to China and live a normal life, they must be grateful to the prince and the prince in their hearts, and it is too late to serve the office, where can they be enemies of the prince and the country? If a prince can't get his brother, how can he get a prince? ”

Qi Xiaogong was ready to take his opinion, but said that he would never recall Gongzi Yuan, because he was the leader of the group of princes and the vanguard against him.

As a result, except for Gongzi Yuan, the other sons were all recalled. The exiles, led by the Childe merchants, took the despicable means of beating the water dogs against Childe Yuan - in order to avoid punishment, they blamed all the crimes on Childe Yuan; In order to make meritorious atonements, they are willing to do the most murderous bad things to Gongzi Yuan; And Qi Xiaogong also vented the depression in his heart by punishing Gongzi Yuan's henchmen.
