If the "Lin Zhengjun" can be successfully tested, it will become a new breakthrough in Huaidong's shipbuilding technology.

The matter of launching the sea trial was extremely important to the military department to the shipyard and the Jinghai Sea Camp. Although the "Lin Zhengjun" is a civilian ship type, and the warship will be built on this basis after the successful sea trial, from the escort guards to the shipwrights and sailors, they are all drawn from the Jinghai Sea Battalion. Hu Qiaozhong, the son of Hu Zhiyong, was appointed as the ship's chief and was responsible for the trial mission of the "Lin Zhengjun".

At that time, navigation mainly relied on experience to navigate, which was traditionally called the comparison method. The vast majority of seagoing vessels have to follow familiar currents and coastlines in order not to get lost. Astrology is still regarded as an evil law by orthodoxy, and only a very small number of shipwrights in the world have mastered it.

Lin Jian had already established the concept of longitude and latitude in his heart, and what he thought was almost a matter of common sense was an extremely difficult advanced knowledge for the people of the world to grasp.

Chen Enze, Hu Qiao and others were able to stand out, not by chance, nor because they were close to Lin Lian, but because they belonged to high-level intellectuals in the current army. They are the most deeply influenced by the forest, and in their respective fields, they show a very high level of professionalism; Although he is young, he already has a bit of Confucian demeanor.

It has only been half a year since the official opening of the Huaidong Ship Master School to recruit students, and after the relatively crude star-pulling method changed to a more accurate vertical method for Lin Jian and Ge Fu, the Jinghai Sea Camp includes the Heishui Society Ship Company, and the talents who can guide the fleet to conduct direct voyages in the vast ocean are very scarce.

For the trial of a new ship type, the structural strength is secondary, and the adaptability of the ship type to wind and waves is the most important criterion. Lin Tie even asked the "Lin Zhengjun" to have the ability to pass through the hurricane area in summer, and such a trial mission is not something ordinary people can do.

Hu Qiaozhong stood at the bow of the ship and led all the crew members to salute Lin Jian and others, who were inspecting the launch of the "Lin Zhengjun" at the dock, and then gave the order to launch the sea trial.

The huge hull of the ship slowly slid from the rails and leaned into the river, making a huge tumbling sound, and the waves that slowly broke the bow of the ship were like white lotus in full bloom. Watching the lively people inside and outside the wharf and on the other side of the dock, only when they got into the water, they were considered successful in shipbuilding, and when they watched the big ship dip into the river and slowly sail away from the wharf, they applauded, waving, clapping, and being extremely excited.

"Today is the full moon wine of the political monarch, you all put aside the things at hand," Lin Lian asked with a smile, "Do you all cross the river with me now?" ”

"That's a drink!" Sun Jingxuan, Hu Zhiyong, Ge Siyu and others should be well, and take a boat with Lin Tie to the north shore.

The ship traveled in the center of the river, and the "Lin Zhengjun" filled the sails and headed for the downstream estuary.

"Isn't three months too little?" Ge Siyu stood at the bow of the ship, looked at the "Lin Zhengjun" going down the river, and said worriedly.

The current craftsmen, accumulating technology, rely more on experience, and are not good at theoretical summary, so the general new ship type may take more than ten years, or even one or two generations before it will finally mature.

Lin Jian gave the "Lin Zhengjun" only three months of sea trials, and after three months, the Guanyintan Shipyard will build two more improved giant ships at the same time.

"Maybe three months is a little shorter, but I'm still too long," Lin Jian said something that sounded contradictory, and explained to Ge Siyu sideways, "I will sign a sea ban today, authorizing the Jinghai Sea Battalion to attack all unreported sea ships in the waters south of Changshan Island, how much time does Si Yu think we have?" ”

"Ahh Ge Siyu was slightly surprised, but he didn't expect to unveil the prelude to the East China Sea today.

"From now on, all ships going to sea from Zhejiang and Fujian, not only the warships of the Zhejiang and Fujian Naval Division, including fishing boats, merchant ships, cargo ships, ferries, etc., will be the targets of the Jinghai Sea Battalion," Lin Jian said slowly, "Not only the sea targets, but also the docks, ship yards, and docks in the coastal waters of Mingzhou Mansion, Jin'an Mansion and the southern Zhejiang Prefectures will be the targets of the Jinghai Sea Battalion!" The warships of the Jinghai Battalion will be fierce wolves and evil tigers, forcing the Zhejiang-Fujian Navy to go to sea and duel with the Jinghai Navy Division at sea! The specific battle plan, Mr. Qin, is being formulated, probably the day after tomorrow, everyone will be able to see ......"

Ge Siyu devoted himself to industrial affairs, and Sun Jingxuan and Hu Zhiyong did not think it was strange that Lin Jian would sign a ban on the sea today, opening the prelude to competing with Zhejiang and Fujian for dominance in the East China Sea.

Zhou Pu and the main force of the cavalry battalion were transferred back from Siyang, and Ge Cunxiong and most of the third water battalion of Jinghai were transferred back from Shanyang and stationed on the front line of Guanyintan; The four newly-built Jinhai-class warships were given priority to replenish the first water battalion.

By September, the First Water Battalion had completed the full establishment of six battalions and increased the number of soldiers, increasing to more than 3,600 soldiers. With the addition of the Chongcheng infantry battalion, the number of soldiers assembled in Huaidong on the Shengsi Islands reached 10,000 for the first time; Including the soldiers, sailors, and sailors, the total strength of the Shengsi Islands reached more than 13,000 people.

The fleet of the Blackwater Shipping Company was also completed by September.

After excluding ships below 1,000 stones, the total capacity of the Heishui Ocean Fleet's long-sea fleet is still maintained at about 240,000 stones, divided into four fleets.

After the personal guard battalion of the Infantry Division transferred elite to Lin Tie to form the Haidong Battalion, he did not receive a supplement, and has maintained the establishment of four battalions. Each fleet was organized into a battalion of soldiers, and the sea ships belonging to the Blackwater Ocean Shipping Company were completely turned into armed merchant ships.

The Goryeo Navy has frequently appeared in the waters east of Dengju, and the Heishui Foreign Shipping Agency, which is responsible for the heavy task of shipping grain directly from Chongzhou to Tianjin, must have enough troops to escort it.

In addition to reorganizing merchant ships into armed merchant ships, the main thing in this reorganization of the Blackwater Ocean Shipping Company is to eliminate all slow-speed sea ships. In the vast sea, it was relatively easy for the grain and sail ships to maintain their speed advantage and escape from the pursuit of the Goryeo naval warships.

In this way, the escort task of the Jinghai Second Water Battalion will be lightened, and part of the main force can be transferred to garrison Jiangmen and become the reserve water battalion for the Shengsi defense line.

The near-sea grain routes from Huaidong to Jiaozhou Bay in Shandong Province have all been changed from Hecheng and Shanyang. The flat-bottomed fishing boats in the Hecheng Fishing Ground have been relocated to the area of Dafeng and Yanqing further north.

In this way, it will be ensured that in the waters south of Hecheng and Changshan Island, only the warships of the Jinghai Battalion and the armed merchant ships of the Heishui Foreign Shipping Company can pass through legally, and all other ships that appear in this sea area will be targets that the Jingshui Battalion can attack!

After nearly three months of deployment, Huaidong has adjusted the posture of attacking the east coast of Zhejiang and Fujian, and Sun Jingxuan and Hu Zhiyong know that if Lin Jian does not sign the sea ban order today, it will not be more than a few days late.

The competition with the luxury family in the East China Sea began with a prelude, and Huaidong wanted to launch an all-round attack, forcing the Zhejiang-Fujian naval division to go to sea to fight, depleting its large sea ships and attacking its shipbuilding capacity. After exhausting the elite warships of the Zhejiang-Fujian Naval Division, no matter how many troops were deployed on the Eastern Front, it would not be useful, but it was an opportunity for Huaidong to forcibly attack Daishan, Changguo and other islands!

Once the war in the East China Sea begins, the Guanyintan Shipyard will mainly focus on building new warships to make up for the war attrition. However, after the war begins, Huaidong's resource consumption will also increase dramatically.

Although the trade route with Haidong has been opened, no matter how rich Haidong's resources are, it must be transported back by ship.

Once the shipbuilding capacity of the Guanyintan Shipyard is mainly focused on the construction of warships, in order to meet the needs of ships on the Haidong route, ultra-large seagoing ships with large capacity and fast speed are more suitable.

Build a "Lin Zhengjun-class" merchant cargo ship, with a carrying capacity of 18 thousand-stone ships. Coupled with the acceleration of the speed, the increase in the speed of loading and the increase in seaworthiness time, the annual transportation capacity of a "Lin Zhengjun-class" merchant cargo ship can almost reach 30 thousand-stone ships.

Another point that is quite crucial is to save manpower.

A transport fleet of thirty thousand-stone ships, with sailors and escorts, needed seven or eight hundred people, to say the least.

For a "Lin Zhengjun-class" merchant cargo ship, the crew and sailors only need twenty or thirty people, and no matter how many escorts there are, more than 100 people are enough. The saved crew and sailors can go to make up for the shortage of the water camp.

This is also the fundamental reason why when the war is becoming more and more tense, Lin Jian also spends so many resources to trial produce super-large sea ships.

The foundation of the luxury family is extremely deep, that is, the complete annihilation of the Zhejiang-Fujian naval division, and it cannot be regarded as the complete defeat of the luxury family's ability to go to sea, and the competition for the sea area south of the Shengsi Islands will be long-term and cruel. The advantages of ultra-large sea vessels in logistics and supply will be more and more obvious.

Song Jia stood aside and was silent, Huaidong and Zhejiang and Fujian always have a time when they separate males and females in the East China Sea, and the luxury family has not thoroughly implemented the strategy of abandoning the land and going to the sea, and may have to taste the bitter fruit!

Sun Jingxuan has been presiding over the Guanyintan Boat Yard for the past two years, and he is quite confident in the warships of the Huaidong Naval Division, standing on Lin Bin's side, facing the river breeze, and said with emotion: "If the luxury family connects southern Zhejiang and northern Fujian together, it will temporarily slow down the momentum of expansion from the land, continue to thoroughly implement the strategy of abandoning the land and going to the sea, and concentrate on the development of the sailors, maybe it will be a different result......

Lin Jian looked at Song Jia and asked, "What do you think?" ”

Song Jia sighed slightly and said: "It is impossible for Luxury Wenzhuang to continue to abandon the strategy of land and sea, and it is an inevitable choice for the luxury family to reshift its focus to the land." Defeating Huaidong first will not be useful to the luxury family, and will only prompt the Yuan family to give up Yanjing in advance and move the capital to Jiangning! ”

"Miss Song is really high-minded, I sighed for a while, but I forgot about the stubble of Jinhai Grain Road." Sun Jingxuan said with a smile.

While the Jinhai Grain Road barely supports the defense line of Yanbei, it is also continuously transporting resources from the south to the north.

Once the Jinhai grain route cannot be maintained, the Yuan clan is likely to decisively abandon the northern route and move the capital to Jiangning. A large area of soil on the northern front, including Yannan, is likely to fall into the hands of the Donghu people, not to mention, after the Yuan clan moves the capital to Jiangning, they will also concentrate more resources and troops to fight Zhejiang and Fujian first.

This situation is even more unfavorable for luxury families.

The luxury family occupies Eastern Fujian and wants to want the world, and the road they can take is extremely narrow, so there are not so many choices; It's not even as good as Huaidong.
