The war was in full swing on the territory of the Japanese state, and the situation in the South Seas, thousands of miles away, was also not calm.

In the past three years, Li Yu has increased his troops to Nanyang on a large scale, accumulating more than 500,000 people to the Nanyang Islands.

At present, 17 prefectures have been established in Nanyang, and the nine major islands in the non-Babin Islands are all under the armed control of the 12 prefectures of the Tang Army, with 300,000 immigrants. The northern and western coasts of Borneo were also under the control of the Bo Ni and Dianzhou prefectures. More than half of the south-central tip of the Polar Peninsula is under the control of the Puluo Central Governorate, which is governed by the Governor of Phuket, which is located on the island of Phuket, and the Governor of Duiju, which was later established in Pattani.

Under the support of the brave and warlike regular troops of the governors and the armed colonization of the immigrants, they unscrupulously squeezed the living space of the aborigines of the Nanyang Islands, robbed them of their land, killed them as slaves and slaves, and drove them to open up wasteland for the Tang Dynasty soldiers and civilians, and build water conservancy roads and bridges.

Nanyang belongs to the tropical rainforest climate, and there are many mosquitoes, insects, ants and beasts that carry various tropical burning diseases, and it is undoubtedly dangerous to cut down trees in the rainforest to clear the wasteland, even if there is artemisinin that Li Yu has tinkered with, it may not be useful sometimes.

After all, artemisinin can only cure malaria, not 100% effective, and driving indigenous slaves to reclaim the rainforest undoubtedly reduces the possibility of immigrants contracting the disease.

As for the barbarians on the Nanyang Islands, who are good at jungle warfare and fierce and difficult to control, such as the Auranglauts, Dayats, Biyans, Maolu and so on. After thorough study and discussion of Li Yu's policy of burning the island, and in light of the actual local conditions, the governors and generals of the prefectures organized manpower to cut down a half-mile-wide and endless fire belt along the edge of the rainforest before the end of the rainy season, and waited until the scorching sun of the dry season dried it, and it only took five or six days to set it on fire.

The flames ignited from the deliberately created fuse belt of the Tang army and continued to burn deeper into the rainforest, especially when the wind was downwind.

Many tree species in tropical rainforests secrete flammable oils, and forest fires during the dry season are tantamount to pouring gasoline on the fires, causing them to burn endlessly, and the flames scatter in the rainforest.

Over the Nanyang Islands under the arson of the Tang army, billowing smoke rose to cover the sky and the sun, even if it was thousands of miles away, a little smoke from the forest fire in Borneo floated in the sky from time to time.

The barbarians hiding in the rainforest were helpless against the Tang army's poisonous tricks, and were either burned alive by the forest fires or forced to migrate deeper into the rainforest. As for how long they can hide, it depends on how fast the Tang Army's immigration development pace.

When the forest fire broke out, the soldiers and civilians of the governor's office covered their mouths and noses with wet towels, and held weapons to ambush and kill the natives who rushed out of the fire outside the fire, so as to solve the problems of the natives once and for all.

The Tang army's extermination of the local natives in the occupied territory undoubtedly caused great panic among the countries in Sumatra, Java, and the Malay Peninsula.

Under the leadership of the two kingdoms of Mora Yu and Sri Buddha, the Sumatra and Mulu kingdoms at the northern tip of Sumatra Island, the Tamara and Haling kingdoms on Jawa Island, the terracotta kingdoms, the Kada kingdoms, Kedah kingdoms, the Jajasgar kingdoms, the Dandan kingdoms, the fifteen-nation alliance and many Malay tribes and other ethnic tribes organized an army of 100,000 people to attack the three prefectures of Pulochung, Phuket and Dui on the polar peninsula and the Dian Prefecture in western Borneo.

Except for the two armies of the nine countries on the Polar Peninsula that came by land, the other two most powerful soldiers and horses all came across the sea.

For the South China Sea Fleet, which had moved its headquarters to Singapore's Yeefon Harbor under the command of the general, the combined fleet of small sampans and small ships carrying no more than twenty or thirty people from the six countries, including the Mora You, Sri Buddha, Sumatra Kingdom, Mulu Kingdom, Tamara, and Haring Kingdom, was simply sent to the door to eat.

The South China Sea Fleet is sorry for itself if it doesn't eat.

Nuo is talking about the islands and inland rivers densely covered with reefs, and the South China Sea Fleet absolutely does not dare to compete with the fleets composed of those small boats of the six countries, but the six countries took the initiative to attack the open sea with high winds and waves, and the South China Sea Fleet laughed up and down.

Xue Yao, who is the commander of the South China Sea Fleet, even boasted about Haikou at the joint military meeting between the Polar Peninsula and the five governors of Borneo: "This time, I promise not to completely annihilate the fleet of the six countries, and I will not see you again, and I would rather draw my sword and commit suicide than survive." ”

After speaking, he led the South China Sea Fleet and a class of generals and colonels to leave, preparing to go on the expedition.

Li Wenchang said with a smile: "Since Commander Xue is confident, then our army has nothing to worry about, we only need to deal with the nine-nation alliance forces on the polar peninsula." ”

"The nine countries on the polar peninsula are only small countries the size of a palm, with only tens of thousands of nationals, only a few thousand soldiers capable of fighting, and more than 20,000 troops with a dozen or so Malay tribes. The troops also attacked the governor's mansions of Phuket and Duju in two ways, and I don't know if their commanders were having a brain pump. ”

Chi Xunyu, the governor of the Boni Prefecture, laughed loudly, with an indescribable mockery of the Nanyang natives on his face.

"According to His Highness's tone, the Nanyang monkeys are all rubbish. Although the 15-nation coalition army has 100,000 soldiers, it is only 100,000 human monkeys who are not much bigger than monkeys and not much smarter. ”

Wei Chi Xunyu smiled and asked the other four governors: "If any of you have insufficient troops and need reinforcements, even if you inform you, you will definitely bring five thousand Eryun from Bo Ni to support you." ”

Li Yexu, the governor of the Governor of Dianzhou, sneered: "Brother Wei Chi still keeps his troops and is optimistic about his own territory, but don't just leave with the front foot, and the back foot will be hidden in the jungle Daya people and Maolu people to attack the city, killing and plundering the army and civilians." The life of every Chinese under our rule is quite precious, and His Royal Highness spent a huge amount of money to move from the Central Plains, and it is quite painful for His Highness to be killed by even one of the natives. ”

"A certain Bo mud doesn't need to worry about Li Dudu, before a certain meeting, he ordered his subordinates to light the ignition belt. After five or six days, the forest fires are estimated to have burned hundreds of miles deep into the rainforest. This will, those Daya and Mao Lu barbarians will either become roasted monkeys, or on the way to escape, how can they have time to find trouble. ”

Wei Chi Xunyu said quite confidently, you must know that he is the governor of Nanyang who has studied Li Yu's strategy of burning the island the most, and he has used it perfectly. In just two years, relying on the two forest fires that were carefully prepared, it was difficult to organize dozens of soldiers to go out of the rainforest to harass the Daya and Maolu people who had suffered a lot of disasters in the Boni territory.

This is beyond the reach of the other four governors, or the other four governors are not as ruthless as Wei Chi Xunyu.

In the past three years, the rainforest in northern Borneo, which is under the jurisdiction of the Bo Ni Governorate, has been burned 200 miles from the coast.
