While intensively repairing Hengyuan Fort, Ouyang Xuan also ordered Huang Dagen to turn Huaguoshan into a fortress as a permanent camp for the navy. On the one hand, the development of the navy is naturally inseparable from water, and the Jiguan Mountain is naturally not suitable, and Hengyuan Fort is to be stationed in a field camp, and Yongqu Township, where the waterway is developed, has no fastened defense buildings, Ouyang Xuan thought about it, and decided to set up the naval camp here. Different from the pure military use of Hengyuan Fort, Huaguo Mountain, which was originally the nest of water bandits, is mainly civilian, and its easy to defend and difficult to attack is not only hidden but also because the only entrance and exit is narrow, but as long as the attacker is not afraid of casualties, it can still be breached, once the village is broken, there is no escape, this is the "dead place" in the art of war. According to Ouyang Xuan's requirements, the Huaguoshan camp must be built for both military and civilian purposes, and can be attacked, retreated, and defended.

From a military point of view, it is not difficult for the Huaguoshan camp to hold on for a long time, only need to strengthen the wall and gate with a small amount of stone, cement and steel, and then set up a few artillery pieces, you can do it in one place, and the difficulty is to evacuate safely after killing and wounding a large number of enemies. Huang Dagen looked carefully in the camp for a few days, and finally found that there was a slightly gentle cliff at the end of the ravine, which was about 100 meters high, except for a huge rock protruding from the middle part, the rest of the place could be climbed with the help of ropes. This boulder is no less than hundreds of thousands of pounds, and it is an insurmountable challenge for manpower, but it is not too difficult for the Thunderbolt army with gunpowder, and it was successfully cleared after a few blasts. With the help of this hidden and treacherous passage, the Thunderbolts can escape from the camp and escape into the dense forests of the Rootless Mountains when they can't hold on, or they can launch a sneak attack from behind the enemy at a critical moment when the battle is tight.

In the initial development plan of the Perak Army in the plains, the headquarters of the Perak Army will be moved here after the completion of Yokohara Fort, and there will be field battalions and internal guard battalions stationed at Yokohara Fort. As the main force of the field battalion stationed here, the Thunderbolt army can advance and retreat and defend, as long as the Yokohara Fort is not breached, the mountains are safe; The Internal Guard Battalion was also stationed here, mainly for the reconnaissance company and the hoe company to go out on duty. As for the guard company and the counter-espionage company, it is also located here because outsiders must pass through this place to enter the mountain, and they can be screened in advance. Outsiders need a guarantor to enter the mountains, and in addition to checking the roads of visitors, sentries and patrol soldiers along the way must also strictly check and search their bodies, and it is almost impossible for spies and spies outside the mountains to blend into the mountains. The garrison battalion led by Yu Zhu was stationed at Wanjiabao, and in addition to the permanent unit teaching company, there were also three basic militia companies stationed in rotation on a regular basis. In accordance with the requirements of the Perak Army's all-soldier and all-staff military training, the garrison battalion has set up 30 militia companies, and the ordinary militia of these companies need to bring their own dry rations for training for three days a month, while the squad and platoon commanders of these militia companies have formed three basic militia companies, which are under semi-full-time management.

In accordance with the decision of the Perak Military and Political Conference, Huang Dagen led three companies of the Water Army Camp to be stationed at Wugen Mountain, with Huaguoshan Camp and Huangjiadang in Yongqu Township as bases. Huang Dagen took advantage of the dry season in early spring to widen the inlet and outlet channels of Huangjiadang a lot, so as to hide the naval warships in it, and at the same time set up defense facilities and material storage points, making preparations for a long-term and protracted war. After the completion of Hengyuan Fort, it will support each other with Huaguoshan Camp and Huangjiadang. Ouyang Xuan understood that such a layout could only allow the Thunderbolt army to gain a firm foothold under the mountain, but if it was to develop in the plain area, it was necessary to use the crisscrossing river and water network of the western Sichuan Plain to build a powerful naval army in order to confront the highly mobile Mongolian cavalry, and the current Thunderbolt army's naval army was still too weak. The navy is a technical service, but it is not easy to expand. On the one hand, compared with the infantry army, the navy consumes more money and resources, and in addition to the need for a large number of craftsmen and wood, the construction period is also long, and the cost of equipping artillery is even more staggering. In the early stage, the artillery used on the naval warships was temporarily transferred from the field battalion, and in the battle of Huangjiadang to exterminate the water bandits, it was found that it was not very suitable for water warfare. Ouyang Xuan has ordered someone to try to produce artillery suitable for warships, but due to the capacity of artillery, it will take time to equip the current twenty warships in place; On the other hand, it will take time to train a contingent of officers and sailors who are skilled in water and water warfare. Now Huang Dagen has taken precautions and began to train the backbone of the navy, and also selected the squad platoon leader to enter the teaching company for further study, but according to Ouyang Xuan's vision, this kind of training is far from keeping up with the scale of the navy in the imagination.

Of course, another way for the rapid expansion of the navy is to accept the annexation of the officers and soldiers of the navy. Although the overall combat strength of the official army is weak, this is caused by the atmosphere of the whole country in which the military is suitable for military play, and there are still many loyal and brave hot-blooded men in the various armies, who can quickly become an army after elimination and selection. It's just that the Thunderbolt Army is still nominally an official army, and even for "friendly forces" like Pan Luohuan, they don't dare to blatantly poach people, and even Yu Laodu, Le Quanan, Liao Loach and others have dealings with their former colleagues at the private level. At first, this kind of exchange was only in terms of friendship, and most of them were the money, grain, salt and cloth of the Thunderbolt army in Jifu City and even the sailors left behind in Xinjin City, and later it expanded to secret business and trade transactions, and the exchanges also changed from sneaky to semi-public. With the deepening of the exchanges, the officers and soldiers of Fucheng and Xinjin City became more and more envious of the governance of the Perak Army, and they became more and more disgusted with Pan Luohuan. The economic connection of "cutting off people's financial routes is like killing their parents" Pan Luohuan can't prohibit it at all, plus his cronies have also benefited, they all turn a blind eye, and he is the only one who is kept in the dark. Regarding the private contact between the Perak soldiers and the remaining naval forces in Fucheng and Xinjin City, Ouyang Xuan not only knew that this was originally his instructions.

Although Ouyang Xuan refused Pan's request for artillery, money and food, and free labor to repair the city, he still sent a batch of farm tools and seeds to Chongqing Mansion City in the name of the Thunderbolt Army from the perspective of the great cause of resisting Mongolia, but Pan Luohuan refused to accept it. Seeing that it was not artillery, money, food, or people to drive, this gentleman put down his cruel words and walked away angrily. He has no interest in the farming that he has worked so hard to cultivate, and he is interested in the intercourse with beautiful women. Huang Dagen asked Liao Loach and Yu Lao to steal the seeds of this farm tool to their former colleagues, which made the sailors very happy. Pan Luohuan disdained to ask for the Thunderbolt Army's seed farming tools, but his soldiers did. If there is no food, Pan Luohuan may not be hungry, but the soldiers under his command will definitely starve.

Chongqing Mansion belongs to the core area of the land of plaster fertilizer in western Sichuan. The land around Fucheng is extremely fertile, and the light and heat conditions are also very good, so you can sow wheat in autumn and grow rice in spring. Most of the land reclaimed by the Perak Army is dry land, and can only grow dry crops such as wheat, sorghum and soybeans. The seeds that Liao Loach and Yu Lao dug up and gave to their former colleagues were mostly rice seeds. The yield per acre of rice is much higher than that of dry crops, but it also requires higher irrigation conditions, which is suitable for planting in plains with developed water networks. However, most of the land on the east bank of the Wenjing River around Fucheng was planted with wheat and other dry crops last autumn, and rice seedlings can be transplanted only after the summer harvest, and there is not much idle land.

Liao Loach and Yu Lao dug suggested that their former comrades go to the west bank of the Wenjing River to open up the wasteland. The main reason why there is a lot of wasteland in the west bank is that it is not convenient to cultivate across the river, especially because the floods in the rainy season make it even more inconvenient to pass. Although the water conservancy facilities in the West Bank have been in disrepair for a long time, the foundation is still there, and it only needs to be rebuilt with great effort. The iron farming tools sent by the Thunderbolt Army this time were extremely sophisticated, and the quality of the weapons even better than many of Pan Luohuan's subordinates. With the right tools and the soft soil, it didn't take long to rebuild the ditch and drain system. Liao Loach and Yu Lao Dig also used the experience of the Perak army to control the Tuntian on the west bank within a mile of the river, and also instructed the excavation of criss-crossing canals and a large number of horse traps on the periphery and interior of the Tuntian, so as to prevent and delay the attack of the Mongol rangers.
