Hua'an refused to pursue the Jianyi immediately on the grounds that the army from all walks of life needed to rest and recuperate, but he was a little curious about the urgency of the Jiaozhou generals' mentality, and after secretly understanding, he learned that the Jiaozhou Legion originally had nearly 20,000 troops, which were deployed in dozens of cities in Jiaozhou, of which there were 5,000 men and horses in Jiaozhi City alone, but in the face of the sudden attack of the 100,000 rebels of the Nanyue tribe, the Jiaozhou Legion suffered heavy casualties.

It is not surprising that the Jiaozhou Legion suffered heavy casualties and was eager to take revenge, but Hua'an had his own considerations, in addition to the fact that several large armies were already tired and needed to rest, there was also a reason to wait for the arrival of Deng Yue, the assassin of Guangzhou.

Deng Yue brought more than 10,000 men and horses on this trip, which can further increase the strength of the Jin army, and at the same time, Hua'an also wants to discuss the next action plan with Deng Yue, after all, Deng Yue has been guarding Jiaoguang and Guangzhou all the year round, and he must know the situation in Jiaozhou better than Hua'an.

In the few days of waiting for Deng Yue's army, Hua An read the military books day and night, thinking about how to deal with the rebels who were good at jungle warfare, and after some careful thinking, Hua An thought of a preliminary method, that is, to formulate a new combat formation.

The main enemy of the Great Jin Dynasty is the Zhao State in the north, therefore, the formation that the Northern Expeditionary Army usually trains is a powerful phalanx composed of thousands of soldiers, although this formation is huge, but it is difficult to exert a strong power in the dense jungle of Jiaozhou, once the army enters the jungle, the original formation will be blocked by the bushes, thus completely losing the role of the formation, so that the Northern Expeditionary Army and the rebels can only rely on personal bravery, in the case of the strength is not dominant, the casualties will be very large, This is something that Huaan can't afford.

In order to change this declining trend, Hua'an thought of the two formations of the Qi family's army's 'Mandarin Duck Formation' and 'Little Sancai Formation' in later generations, which played a huge role in the battle of the Qi family's army to pacify the Japanese invaders, and were a small-scale formation that was extremely suitable for jungle warfare.

Of course, the 'Mandarin Duck Array' of the later Qi Family Army is a team of twelve people, and the Northern Expeditionary Army under the command of Hua'an is a team of ten people.

The structure of the small mandarin duck array is much simpler than that of the mandarin duck array, consisting of two sword and shield soldiers in the front, four pikemen in the middle, and four archers at the end, of which the archers are also equipped with an additional ring-headed knife for hand-to-hand combat.

In places where the terrain is extremely narrow and complex, the small mandarin duck formation can also be broken down into two small three-talent formations, each composed of five people, with a sword and shield soldier in front for cover, two pikemen in the middle for assassination, and the last two archers for long-range shooting and melee combat.

These two formations are mobile and flexible, which greatly increases the adaptability of jungle warfare, and can deal well with rebels who are good at jungle warfare.

After thinking about the formation, Hua'an drew the specific structure of the formation on paper, and then convened the general to explain the essentials, and the subordinate generals in these days of operations, they also tasted the power of the rebel jungle warfare.

The weapons required for the new formation are the main weapons of the Northern Expeditionary Army, so there is no problem of lack of weapons.

Subsequently, the 20,000 infantry of the Northern Expeditionary Army began to redistribute their weapons, and immediately began preliminary adaptation training in the open space inside and outside the city of Jiaozhi to familiarize themselves with the application of the new formation.

The soldiers of the Jiaoguang Erzhou Regiment saw that the Northern Expeditionary Army was trained like this, and they also stood around curiously to watch, at first it was to watch the excitement, but soon, some wise generals saw the great superiority of the Northern Expeditionary Army's formation, which was a formation to restrain the rebels.

For this reason, the generals of the Jiaoguang Erzhou Army asked Hua'an for the mystery of the little mandarin duck array, and Hua'an did not hide it, and told them without reservation, and then, the army of Jiaoguang Erzhou also began to carry out adaptive training, and almost the entire army of Jiaozhi City was training.

A few days later, the three armies were able to familiarize themselves with the new formation, and at this moment, the more than 10,000 troops led by Deng Yue, the assassin of Guangzhou, also arrived in Jiaozhi City.

As soon as he arrived outside Jiaozhi City, Deng Yue saw the soldiers of the three armed forces who were training hard, and he was curious about why these soldiers had chaotic formations, and after a closer look, he gradually discovered some mysteries, and secretly sighed at the mystery of this formation.

Deng Yue rode his horse to a soldier who was training and asked, "Who created this formation?" ”

"General Hui, this is the 'Little Mandarin Duck Array' newly created by General Hua." A colonel of the Northern Expeditionary Army replied truthfully.

Deng Yue stroked his beard, nodded and sighed secretly: "This Hua'an is really young and promising!" After saying that, he led a group of generals to enter Cochin City.

In the government of Jiaozhi City, the generals above the army lord of the Northern Expeditionary Army and the two states of Jiaoguang were all gathered together, Deng Yue and Hua'an had the largest official positions, sitting at the top, and the rest of the generals were divided into two sides according to the size of their official positions.

The generals sat down, and Wang San, the deputy general of the Northern Expeditionary Army, made a detailed report on the movements of the rebels detected by the scouts in accordance with Hua'an's instructions, carefully analyzed the combat strength and operational characteristics of the rebels, and put forward his own counterinsurgency strategy.

The generals listened, some agreed and some opposed, and then, the generals also put forward some of their own opinions, and the atmosphere in the lobby was very lively.

Deng Yue, who was sitting at the top, looked at Hua An beside him and said: "General Hua, as soon as the old man arrived in Jiaozhi City, he saw the soldiers practicing a new formation, and after careful questioning, he learned that it was General Hua's newly created 'Little Mandarin Duck Formation', which is very good, and in the old man's opinion, it is enough to restrain the rebels in Jiaozhou." ”

"Haha! Deng Thorn Shi has won the award, and the carving insect is just a small skill. Hua An said politely, and asked casually: "Deng Tingshi has been guarding the Jiaoguang Erzhou of the Great Jin Dynasty all the year round, and he must have a deep understanding of the Nanyue people, so he must have a counterinsurgency strategy in his heart!" Hua'an is willing to listen. ”

When Deng Yue heard this, he frowned, and then said with a dry smile: "Haha! General Hua said seriously, although the old man knows a lot about the Nanyue people, he is also not confident in how to completely quell the rebellion! Jiaozhou is extremely remote, is a barren land, the Nanyue people are barbaric and fierce, do not respect the king, want to completely conquer the Nanyue people, so that they are happy and convinced to submit to the Great Jin, it is not an easy task. ”

Deng Yue said the truth, he sits in Panyu City all the year round, there are still more than 1,000 miles away from Jiaozhi City, the northernmost city of Jiaozhou, and two or three thousand miles away from the southernmost Xianglin City.
