When Zhang San arrived at the palace, not only was there no resistance in the city, but even the residents of the city were locked up at the dock to supervise and prepare for loading, so Zhang San entered an empty city, and there was still a lot of stock in the treasury of the palace, at least to earn back the military expenses for this expedition.

After Zhang San stayed here for three days and the troops changed their guards, the Praetorian Guards immediately assembled and marched south, this time the Praetorian Guards will advance by land, the first is to test the speed of land transport artillery, and the other is to test the field combat capability of the new army.

Because the southern country received the news of the destruction of the northern kingdom, it moved the capital from the sea to the inland area a hundred miles away almost overnight, and stationed 20,000 troops in the place where the sea and the northern kingdom met.

Therefore, this time the Praetorian Guard will face the attack of the local formed troops, which is a good opportunity to test the combat strength, and the troops marched for two days to reach the border of the southern country, and the two armies finally met at the border.

Although Zhang San has always called the other party a savage, these people have been ruled by civilization after all, and this side was once the rule of the Three Buddhas, so although the army is not as professional as the Wa Kingdom, it is also stronger than those tribal warriors.

The strong place is that it has been replaced with a wave and plans to rush up in batches and directions, the other side has 20,000 people, and Zhang San's side only has 10,000, but Zhang San's side is divided into ten battalions to fight.

Therefore, the surprise attack of the opponent trying to bypass the frontal battlefield was always blocked by the Praetorian Guards, and it turned into a frontal battle, and the continuous fire of the musket raised a large cloud of smoke, which was the protagonist of the battlefield until the invention of smokeless gunpowder, not only blocking the enemy's offensive route, but also blocking the view of the musketeers.

However, for platoon gun tactics, all that is needed is continuous shooting, and as for the accuracy and hit rate, we don't have to worry about it at all, we just need to keep shooting and organize the enemy to approach.

Zhang San stood on a high place and could see that on the battlefield, the Praetorian Guards had been on the defensive, but the soldiers on the opposite side hesitated in the face of huge casualties after attacking for a period of time, and Zhang San ordered to blow the horn of the attack.

Hearing the sound of the trumpet, the round shield bearers in the front row got up from the crouching state, began to shout the trumpet, and walked forward in unison, the musketeers in the back also no longer retreated but reloaded in place after firing, and the musketeers in the back row stepped past these people and continued to shoot in front, and then reloaded in place, and the rear ones were forward.

This is the so-called state of attack forward, and the soldiers on the opposite side really couldn't stand this kind of slaughtering shooting, and finally collapsed after firing a few more rounds and the Praetorian Guard advanced more than thirty steps.

Zhang San has been watching the changes in his standing and the state of the troops, because there is no actual contact between the two sides, so there will be no casualties on the side of the Praetorian Guard, and seeing that the other party has collapsed, Zhang San immediately ordered the cavalry battalion to attack.

The cavalry battalion of the Praetorian Guard thought that the transportation was inconvenient and had been unloaded and repaired in Zhenpo Port, and then waited until the horsepower was restored and rushed over from the north of the island.

However, in the end, three or four thousand enemies fled into the mountains and forests, there were too many trees here, there was not too much open space at all, and there were woods less than three hundred meters on both sides of the battlefield, so Zhang San had no way to stop it.

It took another day to capture the slaves and repair the team, Zhang Sancai continued to advance with the troops, and after a day of marching, he finally arrived at the other party's royal city, this time the other party did not go out of the city to meet the enemy, but planned to rely on the city wall to defend it.

Although in Zhang San's eyes, this kind of three- or four-meter-high city wall is useless, but it still gives the enemy great confidence, but Zhang San's hard work to pull the cannon is not a decoration, so the ending is already doomed.

The next day the attack began, Zhang San's troops set up a formation, artillery was also deployed in place, with Zhang San's first order, in the rumbling, cannonballs flew to the opponent's city walls and city heads.

It's just that the artillery unit has not been established for a long time after all, so there is still a lack of accuracy, so it took three rounds of fighting before shells began to hit the city wall, as long as they hit the opponent's city wall, the opponent's city wall will appear more or less a gap, which makes the other party become entangled.

Zhang San did not attack, and it was difficult to bombard quickly and slowly for a morning, and at first the people in the city began to try to repair the city wall, but in the end after a few volleys of fire from the musket battalion, they abandoned this idea.

In the afternoon, there was no suspense in the siege battle, the musket battalion came to the gap in the wall, the shield bearer entered in front, and the musketeer in the back carefully aimed at anyone who came up and snapped a few shots, and slowly but steadily entered the city.

Zhang San was afraid that the enemy would try to fight in the streets, so he did not let the troops go deeper, but gave priority to occupying the city gate and clearing the remnants of the enemy on the city wall, after all, he only had 10,000, and the other party did have 40,000, and if he dared to enter the city, he really engaged in a street battle, then it would cause heavy losses.

Zhang San used the strategy of occupying the city wall and then clearing the city in divisions, and finally occupying the city steadily, the strategy was a good strategy, but when Zhang San was still clearing the city wall, the enemy fled from the other side of the city gate.

Zhang San had to send cavalry to try to drag the enemy and then let the infantry reinforce it, but the cavalry collapsed on the opposite side of a charge, running all over the mountains, Zhang San had to be ashamed, this kind of play really didn't know whether to speed up the clearance work or add chaos.

Although the enemy was quickly defeated, a large number of enemies fled into the mountains and forests, which undoubtedly increased the difficulty of clearing the army, and the result was that the training effect was very limited.

In desperation, Zhang San had no choice but to let the forbidden army also start to join the liquidation according to the battalion unit, while Zhang San himself was ready to go around Borneo, and the first job was to entertain the representatives of Chinese businessmen.

These Chinese businessmen, who have been operating here for a long time, are familiar with the local area, and with their assistance, Zhang San's immigration work can also be speeded up a little, although the Chinese have accumulated a lot of wealth here, but they have always been a vulnerable group, and now there is a Han regime rule, everyone is still very happy.

However, the Chinese here do occupy a large amount of social resources, so Zhang San re-cleaned up their property, and the land property rights were owned by Zhang San and redistributed, while their money, goods and shops were not included in the scope of recycling.

Because Zhang San's investigation found that almost seventy percent of the shops and ninety percent of the ports and wharves in these cities were owned by the Chinese, and the Chinese also bought a large amount of mountain forests and wasteland, etc., Zhang San would have no fun if he didn't clean himself up.

Of course, for the sake of the face of everyone who is Han Chinese, Zhang San still gave money, anyway, Zhang San is now minting more and more copper coins, Zhang San is not short of money, these people spend the money in other places to increase the circulation of Ryukyu copper coins.
