With the current geographical environment, it can be regarded as the former Lu Zhe's army, and the tenacity of the current Han army is good, after all, in the desolate primeval forest environment, it is extremely difficult to march even without engaging the enemy army.

The control of the Lingnan region by the new Han State is still very weak, and the ability to establish a garrison base smoothly is still based on the premise that the various ethnic groups in Lingnan have fled one after another without frequent raids, and in order to complete the fact of its occupation, all roads need to be repaired, and at least the situation in the area must be considered to be truly stable.

Luo Shao continued to send small troops to harass Ou Yu with the consent of Lu Zhe, and each raid was to make advance preparations for the continuation of the army in the future, and the intention was nothing more than armed exploration of the terrain, and it was not until the small force sent out discovered the road built by Kai Mingpan himself that the situation changed.

When Kaiming Pan led his army north, he built a simple road, which could provide passage for 30,000 troops, although the passage had been partially destroyed by the time the Han army discovered it, but most of the area was still available for large troops.

Luo Shao reported the military intelligence report that had discovered the ready-made passage to the Nanling Center, and Lu Zhe nodded and promised Luo Shao to change his plans for the new fighters, and a large-scale invasion of the Ou Kingdom was put on the table.

When the Southern Expeditionary Army occupied the Lingnan region, it conquered many Lingnan natives who did not migrate, some of these natives surrendered and sacrificed young men and women, some were wiped out by the army, and the disappearance of a large number of tribes contributed a large number of labor to the Han army.

There were nearly 40,000 indigenous slaves who had been driven to repair the discovered passage, and Luo Shao's plan was to concentrate 60,000 Han troops, and to reserve enough war materials before the passage was reopened, and to launch an invasion of the Ouluo Kingdom in the non-rainy season when it was ready.

Non-rainy season? In this part of South Asia, there is only a short period of three months in summer, and the rest of the spring, autumn and winter are basically the rainy seasons of three to five days, of which the rainy season in spring and autumn is the longest.

Is it possible to destroy a country in March? Luo Shao's return to the center of Nanling was that it was impossible to destroy the Ou Kingdom within three months, and the total population of the Ou Kingdom he had explored should be about 800,000, and its territory should be about 30,000 square kilometers. The number of troops in the country is currently maintained at 120,000.

There are many tricky ones, for example, the territory of the Ouluo Kingdom is a long and narrow shape, and the rivers on the other side seem to be frightening, and more importantly, the Ouluo Kingdom seems to be a country with a high level of civilization, and its army is equipped with more crossbows than the countries of the Central Plains, and the other is that the Ouluo Kingdom also has a force of thousands of war elephants.

The territory of the Ouluo country is long and narrow, and it is completely conceivable that the development of primeval forests is difficult in these years, and they will definitely choose the land closer to the coastline for development, after all, the dense forests in the interior of South Asia are easy to occupy under the three intermittent rainy seasons a year, but how about development......

It is easier to understand that the civilization of the Ou Yu Kingdom is not low. This country was established after Qin destroyed Shu and the royal power of the ancient Shu State, the first generation of kings was the enlightened system (Shu system), and the second generation of kings was still reigning Enlightened Pan (Shu Pan), they brought the civilization and system of the ancient Shu Kingdom, and it was the use of the height of civilization to quickly conquer the local Ou people and the Luo people.

According to the records of the "Dongxi Xianzhi", they are "located outside the ridge surface, shooting for life, devouring insects", and basically live by hunting. The characteristic of the group is to eat insects such as centipedes.

Speaking of crossbows, "Huayang Guozhi? Nanzhong Chronicles records that "Wu people love the bamboo bow and crossbow on the side of Shu", which shows that the combat effectiveness of the Shu crossbow is not weak. King Anyang (Kaiming Pan) is from Shudi, and his achievements in the bow and crossbow are basically not low.

Luo Shao also reported a lot of useful information to the Nanling Center. Among them, the information that "the place occupied by the exiled nobles of Shu is the area where the Red River lingers, and it must converge into Zeguo every rainy season" is the most important.

Zeguo, what kind of scene should that be? Just look at Yun Mengze in Nanjun and you should know. In the rainy season, Yunmengze is an area like an ocean.

The rainy season in South Asia is often continuous, which means that if a war of annihilation cannot be formed quickly, the time of year for large-scale military operations is the three months of summer. The rest of the time they could only hide in buildings or tents to avoid the rain, which was a very foreign mode of warfare for the Han army, and it was necessary to consider whether the army would be defeated by the army of the Ou Kingdom or destroyed by the weather.

The ministers of the nascent Han Kingdom had never understood why their king had a "soft spot" for the land that always liked to rain, and they generally thought that Lingnan was already desolate enough, and now they were nailed to the more distant area that would become Zeguo at every turn, and they were extremely skeptical that there was a need for that.

In a real sense, there is really no need to occupy South Asia at this stage of civilization, after all, there are really rainforests everywhere, and there is not much development value in terms of current productivity.

The army has always been a restless collective, and the meaning of their existence is to fight, and if Lu Zhe is not looking for enemies in the south, the army's eyes will be fixed on the north, and it will inevitably participate in the war of the nations prematurely, which Lu Zhe does not want to see at this stage.

Lu Zhe's development and construction of the navy was intended to use practical actions to warn Sù that the military operation against the southwest was not a fool's errand, and if he remembered correctly, the area of Jiaozhi had the best iron ore and coal mines in Asia, and it seemed that it was not very difficult to mine.

Once there was a full-fledged navy, the Han occupation of Jiaozhi enabled them to exploit iron and coal mines, which were then transported back to China by sea. In fact, even if it is not shipped back to the mainland, it is a good choice to build the corresponding industry there, and in a way, it can also induce the Chinese regime to firmly occupy that land and dare not give it up lightly.

The land of Jiaozhi not only has high-quality iron ore and coal mines, but also some precious timber is also available all over the land, and the military cost of occupying that area may not be low in terms of economic effect, but the return will inevitably be more generous.

Another point is the fact that Lu Zhe has revealed many times, there are many islands across the sea from Jiaozhi, and those islands are rich in spices.

For centuries, the earth traded around spices, and the Netherlands, which was a little bigger, became the world's top power because of its mastery of spices.

It is now 216 B.C., and many places are basically terra nullius, so if you have enough strength to grab the ownership of the land first, should you give it to others? Even if that kind of ownership is to bury a boundary monument to declare sovereignty, Lu Zhe believes that it must be done.

Under Lu Zheli's disapproval, the military campaign against the south will not stop, even if the Ou Yu Kingdom is destroyed, and the army will continue to explore South Asia, killing and looting there, bringing iron and fire to the monkeys living in that land.

In fact, Lu Zhe had been planning to conquer South Asia all along, and the occupation of Vietnam was one of them, and the next target of the army would be Burma, a region rich in jade, and then some land that produced gold and diamonds.

Before the navy was built and developed, Lü Zhe's conquest probably stopped in southern South Asia, and it would probably be Vietnam, Burma, Laos, and Thailand in the future. After the development of the navy, the second step will be Malaysia and the Philippines in the future, and the third step will be to explore the Indian Ocean.

If Lu Zhe's memory is not wrong, South Asia was a void of power in the BC period, and there were only some primitive tribes living there, plundering and conquering with state-like violent organs, and there was an army with a structure and division of labor to face those Stone Age people with the superiority of civilization, and the real enemy would be the natural environment and not those monkeys.

Now, after seven months of preparation, Luo Shao has launched his first military operation against the Ouluo State, crossing the local river named "Shanglong River", and the first batch of 5,000 forward troops have engaged the troops of the Ouluo State.

The first batch of troops of the Han Army's Southern Expeditionary Corps was basically composed of naturalized young people of all ethnic groups in Baiyue, and the officers were Chinese and Luo Shao's Eastern European ethnic groups.

It seems that the Ouluo Kingdom has long known that the Han army is coming, and they have concentrated about 70,000 troops to arrange the first line of defense, and the group of Ouluo troops encountered by the Southern Expeditionary Army may be a group of elites, not only equipped with a large number of crossbows and war elephants, but also dispatched a lot.

The vanguard of the 5,000 Southern Expeditionary Corps did not immediately break out into battle when they encountered the army of the Ou Kingdom, and Kai Mingpan sent envoys to ask to meet the commander of the Han army, which clearly explained the intention.

The envoys of Kaimingpan came to clarify the misunderstanding, they said that the previous time they went to Lingnan because they learned that the Qin army was going south, and the reason why they sent troops was to avenge the hatred of the Qin State for destroying the ancient Shu State, and they immediately retreated after discovering that it was not the Qin army that went south, and they did not mean to be enemies of the new Han State.

Oh! The Ou Kingdom actually knew that Lu Zhe had established the Han State, so does it mean that the Ou Kingdom has been paying attention to Lu Zhe's forces?

Kai Mingpan made it clear that he could make amends for his last actions and hoped to dissolve the hostile relations between the two sides, for which they were willing to pay an acceptable price. He also said that since the Han king established the country independently, then there would definitely be a war with the Qin state in the future, so they had the same goal.

Yes, the Ou Kingdom must have probed Lu Zhe's power in many ways, otherwise it wouldn't be afraid...... (To be continued......)
