The city of Jiexu in Hainan Province, the Natuna Islands and the Annabas Islands, which were newly incorporated into Chinese territory. Zhang Jiexu, a native of Chaozhou, Guangdong, once established a soil kingdom here, in order to show the Chinese attributes of this place, so the entire administrative region was named after Jiexu City. Originally, there were a large number of Indonesians on the island, but after PLA landed on the island, they were basically sent back to the Lesser Sunda Islands, and later some immigrants were carried out here, so the total population of Jiexu City has exceeded 100,000, mainly engaged in fishing and planting.

In addition, the PLA Navy has also established a new naval base on the island of Natuna, where there is no strong force to deploy at present, but when the base is completed, the PLA Navy intends to deploy an amphibious assault group here to control the waters of the South China Sea.

In the past few days, the archipelago of Jiexu City has been very lively, and China and Nanyang have launched a joint military exercise on the island, "Operation Jingcheng". This military exercise is the first of its kind, and it is planned to hold it once a year to deepen the relations and cooperation between the two militaries. However, in addition to the Red Alert soldiers in the Nanyang Defense Force, who are former PLA veterans, there is nothing unfamiliar with the two sides.

The joint military exercise of Operation Sincere is mainly a series of "anti-landing-island seizure" exercises, which are relatively targeted, that is, military deduction and actual combat training based on the situation in which the islands and reefs of the two countries in the South China Sea are attacked or seized. The scale of this joint military exercise is not small, the Chinese side dispatched an amphibious battle group, a Marine Corps brigade, and dozens of aircraft of various types of naval aviation, while the Nanyang side sent a small fleet, including one 052A destroyer, one 054A frigate, a tank landing ship, and an ocean-going supply ship. In addition, they sent six infantry battalions to participate in the exercise.

The total number of people involved in the exercise exceeded 7,000, which was definitely a very large-scale military exercise in this era. Qi Yiming himself also went to Jiexu City with great interest to observe this military exercise, although he engaged in a lot of bloody wars, but he really watched the actual combat training of weapons is not much.

According to the exercise script, the PLA side will play the role of the landing operation side, and the Nanyang Defense Force (NDF) will conduct an island defense operation, and the entire forces of both sides will be engaged in actual combat, and the confrontation will be carried out as close to the actual combat as possible.

The core of the PLA attack is naturally the amphibious assault ship Hainan, which has been in active service for nearly four years since 1985 and has participated in many major military operations. However, after the Type 075 40,000-ton amphibious assault ship began to enter active service, the actual combat role of the Hainan and Shangri-La was greatly reduced. Now it often appears, but it is just to hide people's eyes and ears and prevent people from discovering the existence of China's more powerful large amphibious assault ships.

In fact, from the day they appeared, the Hainan and Shangri-La basically took the path of LHA, that is, helicopter carrier. Because both ships were converted from old aircraft carriers, they did not have dock compartments and did not have the ability to land with armor, so they could only deliver lighter troops vertically. Of course, because of the presence of the J-8V in the PLA,
