Since the successful robbery and robbery in Enzhou in the Southern Han Dynasty on September 5, the three pirate leaders of Jia Yuhang, Cao Shang, and Yi Wuxian have doubled their confidence, and with the two sharp weapons of binoculars and compasses, they have led their fleets to hang far from the coast to the south, and from time to time they have irregularly raided the coastal fishing ports and fishing villages of Luozhou (now Lianjiang, Guangdong), Leizhou (now Leizhou, Guangdong) and other coastal fishing ports and even villages on the shore in accordance with the "frog jumping tactics" taught by Lin Feng.

They were prepared to attack unprepared, and they were one blow and left, each time they succeeded smoothly, grabbing more and more property, and plundering more and more Southern Han soldiers, Lang Lang and young women, the whole fleet became a huge team with thirty-four large and small ships, and the speed of the assault became slower and slower.

Therefore, when they came to the sea area east of Xuwen County at the southern tip of the Leizhou Peninsula, the three thieves began to discuss where to set up their first overseas base. However, as soon as the three of them mentioned their own ideas, they immediately quarreled.

According to Jia Yuhang's idea, he directly took all the Southern Han warships in the Qiongzhou Strait, and then occupied the entire Qiongzhou Island and established a large overseas base.

Yi Wuxian unceremoniously reprimanded him for being too arrogant, and with the existing 2,000 people, he wanted to swallow the entire five states and twenty counties on Qiongzhou Island, including Yazhou, Danzhou, Zhenzhou, Wan'an, and Qiongzhou.

Jia Yuhang naturally has his own reasons, according to Lin Feng's speculation, the Southern Han is very likely to go north to attack the Southern Tang with all his might, and the main fleet will inevitably follow, if he takes advantage of the situation at that time, it is not impossible to take the entire Qiongzhou Island, the goal should be set more ambitious!

The two had a dispute, and finally had to compromise, first choosing a state that could be attacked and defended on Qiongzhou Island, and then expanding outward.

The two sides had just decided to target Wan'an Prefecture (now Wanning, Hainan) in the southwest corner of Qiongzhou Island, and after finalizing the plan for the siege, they quarreled over the next strategy after the siege.

Jia Yuhang still adheres to the usual practice during this time, opening the way by force and coercing more people to join the team. Yi Wuxian resolutely disagreed, believing that it was just a method of robbery, not a method of establishing a base area, and that a policy of Huairou should be adopted, and after seizing the city, open a warehouse to release grain and distribute money, exempt from rent and taxes, treat the local people well, and truly turn this place into his own territory.

Jia Yuhang slapped the table and shouted, bluntly reprimanding this method as too weak and time-consuming, which would delay Lord Lin Fenglin's long-term plan.

Yi Wuxian was also on fire, smashed the table in front of him with all his palm, and directly proposed: Everyone will scatter from now on, and go their own way.

Even if Jia Yuhang was willing to split up in his heart, he was unwilling to show it directly, so he took a step back and proposed a compromise method, the two sides worked together to attack Wanning Prefecture, and after the city was broken, the captured soldiers were handed over to him, and he led the team to continue south, opening the way for the Yi people in front.

This move was exactly what Yi Wuji wanted, and he immediately agreed.

On the morning of 14 September, a pirate team with only three large ships raided Dazhou Island in the sea southwest of Wan'an Prefecture and swept away all the 30 soldiers stationed on the island, but deliberately spared the head of the army.

The head of the capital left in a hurry and urgently told Shi Hong Tianyi, the assassin of Wan'an Prefecture.

On the afternoon of 15 September, Hong sent only ten ships full of soldiers to Dazhou Island to sweep away pirates. The encirclement force circled the island and the island several times, but did not find a single anomalous ship or pirate.

Late that night, when the fleet commander ordered all the ships to stay on the west coast of Dazhou Island and wait, the pirate vanguard that had already entered Wan'an Prefecture City a day in advance was led by the fierce man Cao Shang, raided the eastern city, easily descended, and then put all the pirate teams lurking under the city into the city; At the same time, Jia Yuhang and Yi Wuxian led a selected master to raid the Assassin's Mansion and successfully captured the Assassin Hong Tianyi.

Then things went well: the captured Hong Tianyi had to order the remaining 1,000 soldiers in Wan'an Prefecture to give up resistance, and at the same time drafted an order to send a fleet back to the city, which was sent to Dazhou Island by a pirate disguised as a soldier.

The unsuspecting encirclement and suppression troops easily returned home, only to be surrounded by a large group of pirates in a valley under the Siwei Ridge, Hong Tianyi appeared on the scene and ordered them to give up resistance, and the 800 soldiers had to abandon their weapons and surrender.

On the morning of 17 September, Jia Yuhang, who was like an arrow, wrapped up 1,500 soldiers of the Southern Han Dynasty and continued southward on 20 large ships. At noon that day, Yi Wuxian led the remaining expeditionary personnel to gather the people of the city at the east gate of Wanning Prefecture and announced a series of measures:

The first article states that the Southern Han Dynasty repeatedly violated the Tang Dynasty for no reason, and the Tang Dynasty came to crusade, and immediately Wanning Prefecture belonged to the Tang Dynasty; But the soldiers of Wanning Prefecture are innocent, the people are innocent, and they promise not to pursue anyone's war crimes;

Article 2, Hong Tianyi publicly listed the crimes of oppressing the people, collecting money, etc., and put him in prison;

Although the first two policies caused an uproar at the scene, the two policies announced later immediately made all the people raise their arms and shout:

Article 3: From now on, Wan'an Prefecture will open warehouses to release grain, open warehouses and release money, and the whole city will receive grain and treasury according to the capitation, and at the same time announce that the people in Wan'an Prefecture will be exempted from paying rent for three years;

Article 4: The people of all ethnic groups in Wan'an Prefecture are equal, and people of any tribe can join the Datang Free Army, with a monthly salary of 300 wen and all the spoils of war divided equally.

This practice of dividing the gold and grain in a big way immediately captured the hearts of the people of Wan'an Prefecture, the hostility melted away like thin snow, and the atmosphere became as warm as spring. In particular, the last one quickly spread in the state, attracting more and more Li masters in the mountains to go down the mountain and compete to join the Tang Free Army.

Under the mutual influence of such favorable factors, the entire Wan'an Prefecture was successfully transformed almost within a few days, from a state in the Southern Han Dynasty to an overseas enclave in the Southern Tang Dynasty, and Yi Wuxian also became the de facto history of Wan'an Prefecture.

However, when the expansion of the base area in Wan'an Prefecture was going smoothly, Jia Yuhang, who led the fleet south, turned west again, killed near the coast, and after a series of lurking points, the target of the first operation was a natural seaport near Lu Rong (i.e., the later Hue) (i.e., the later Vietnamese Yan Port).

Lu Rong has been the homeland of China since ancient times, under the jurisdiction of Rinan County of Jiaozhou (Jiaoluan) of the Han Dynasty, and it is also the place where Lin Feng mentioned before that it is rich in Zhancheng rice.

In 111 B.C., Emperor Wu of the Han Dynasty destroyed the Nanyue Kingdom and set up three counties of Jiaozhi, Jiuzhen and Rinan in northern Vietnam, and incorporated this land into the administration.

At the end of the Eastern Han Dynasty (192 AD), the Cham people killed the Han Dynasty's Rinam County Xianglin County, became independent from the Eastern Han Dynasty, occupied most of the original Yen Nam County (central Vietnam), took Brahmanism as the state religion, established the Cham state, and the Eastern Han Dynasty with Hue as the boundary.

Later, in the late Tang Dynasty and the Five Dynasties, Jiaozhi (also known as Jiaozhou) in the north of the Cham country began to fight for many years: in 931 AD, Yang Tingyi, the former Aizhou (now Thanh Hoa, Vietnam) guard, entered Jiaozhou, and Liu Yan, the king of the Southern Han Dynasty, sent troops to rescue but failed, so he had to recognize Yang Tingyi as the envoy of Jiaozhou. In 937 AD, Yang Tingyi was killed by Jiaozhou general Jiao Gongxian, and the next year, Yang Tingyi's subordinate Wu Quan raised troops from Aizhou to attack Jiao Gongxian, and Gongxian then asked for help from the Southern Han Dynasty. Before the arrival of the Southern Han army, Wu Quan had already killed Jiao Gongxian and first occupied Jiaozhou and established himself as the envoy of Jiedu.

In 939 AD, the Southern Han reinforcements were defeated by Wu Quan at the Baiteng River, and Liu Hongcao, the king of the Southern Han Dynasty, was killed in battle. In that year, Wu Quan was called the king, and the capital was Guluo. Of course, in order to keep a low profile, Wu Quan did not have a date name, and history had to call this period of time the Wu Dynasty.

Wu Quan died in 944 AD, and before his death, he bequeathed Empress Yang's brother Yang Sange to assist his son. Shortly thereafter, Yang Sange usurped the throne and proclaimed himself King Yang Ping, controlling Wu Quan's second son Wu Changwen and others, while his eldest son Wu Changqi fled in chaos. With his example, the twelve great feudal lords of the entire Annam region have ceded land and fought with each other, that is, the famous rebellion of the twelve envoys in history.

In 950 AD, there was a rebellion in Taiping and Tang Ruan villages, and Yang Sange sent Wu Quan's second sons Wu Changwen, Yang Jili, and Du Jingshuo to lead the army to conscript. During the march, Wu Changwen launched a mutiny, vowing to avenge his father, and the general Du Jingshuo and others supported him and officially began the crusade against Yang Sange.

It stands to reason that Jia Yuhang's location of their attack is the junction of the Wu Dynasty and the Champa countries, in terms of time, at this time, the northern Wu Dynasty is the key time for the king to divide the territory and the two kings to compete for the throne, this choice of attack is not wrong, but the Jia Yuhang fleet, which has been very smooth since the south, has fallen into a passive situation from the beginning.
