Because it is located in the deep sea, there are hardly any decent islands in the sea area where the whole army is advancing, and it is absolutely impossible to establish a defense line in such a place in the past.

But this problem has been solved by Tang Ling, and the mobile defense line established by the fortress ship as the main body has now been more perfect.

In addition to the original "" type of defense, there is now an "O" type, but its main task is not to fight or defend, but to create artificial islands in the vast ocean.

With a diameter of more than 10 kilometers and a width of nearly 1 kilometer, the entire "O" shaped artificial island can be expanded several times as long as an upper deck is erected in the center of the artificial island.

The power source of the artificial island has also changed from a fortress ship to a beast-like warship, and nearly a hundred conventional general-class beast-like warships are fixed under the artificial island, and in case of emergency, as long as the artificial island is separated, it can be turned into a hundred beast-like warships to quickly evacuate, which is obviously far more than the "" type of defense line in terms of flexibility.

An O-shaped artificial island with four "" shaped defensive lines can form a fortress that holds on to the ocean.

On the artificial island, farmland, vegetable fields, orchards, and desalination systems are fully equipped with logistical facilities, and as long as the breeding cages are hung under the central area of the artificial island, a large number of artificial seafood can be cultivated.

Not only that, but a small part of the crop production can also support a certain number of livestock and poultry on the artificial island, whether it is the beast warship that brings back sediment directly from the seabed, or the artificial fertilizer made from the excrement of soldiers, the system on the artificial island can be well maintained.

In this way, such an artificial island would have no problem at all to feed the fleet of four lines of defense plus one detachment.

When Tang Ling led the fleet to fight 500 kilometers of blood, the progress of the attack was suspended, and then under his leadership, Zhou Tianbao, the head of the logistics department, immediately began to build this artificial island defense line on the spot.

The hundred conventional general-class beast-like warships are nothing more than the most common anchovy in the ocean in terms of appearance, and in the case, normal anchovy are at most tens of meters long even in this world.

However, with the current creation technology of Baoling Island, even if you don't use the corpse of a sea beast, you can already create this super-large anchovy beast warship by yourself with various sea beast materials.

Because they are not main combat units, they do not have large-caliber artillery except for some self-defense weapons and gold-level beast-like skin armor, but the streamlined hull makes them very fast in the sea, and they are definitely good at running after the separation of artificial islands.

As for the number of terrifying battleship builders on the 0521, the creation of these 100 general-class beast warships did not need Zhang Yuanzhen to worry about them, and the battleship was deployed in the sea first, and the logistics department quickly began to build the main body of the artificial island on the back of the battleship.

The appearance and splicing of the deck was very fast, and the only trouble was the construction of the island's facilities.

This kind of work can only be handed over to a few people who have mastered Tang Ling's creation of formation talismans, and some of these creation formations are directly Tang Ling's practice of the research results of the creation law BUG.

Through them, the battleship builders of the Logistics Department were able to create the refined steel, as well as various other materials, in true proportions, which could only be done in the small shipyards on the Tortoiseshell supply ships.

Once built, it is installed directly on the deck of the artificial island.

Then, as long as the soil on the supply ship is transported to the artificial island, the logistics system is completed.

In the end, it only takes a few debugging and a few retreat maneuvers to complete the entire artificial island.

"From now on, the battleship builder should probably be called the builder!" Standing on the newly completed artificial island, Zhuge sighed.

"Tang Ling, this kid's creation system has broken the restrictions of the creation law, although it is not much, but when he completes the creation pattern to the grandmaster level, in the future, the battleship builders who master these creation formation patterns, as long as there are sufficient materials, they will be able to create a sea city out of thin air!" Xuanyuan answered.

"The afterlife is terrifying!" Duanmu sighed.

At the same time, Tang Ling began to introduce Zhang Yuanzhen to the use of artificial islands.

"Uncle Yuan Zhen, there are connections in the four directions of the artificial island, east, west, north and south, which can be docked with the four defense lines at the same time."

At the same time, the artificial island is also divided into four zones: southeast, south, and northwest, and the northern zone is the military zone, where the headquarters, radar systems, and weapon systems are located; The east and west areas are living quarters, which are full of daily service facilities, and it is best to give the soldiers a day off every week in the future to let them relax. ”

"The relatively safe southern zone is a production area, where farmland, orchards, vegetable fields, desalination systems, and livestock and poultry breeding areas are located, so I suggest that the southern defense line connected to it should be better to reduce the proportion of weapons systems and replace them with logistics facilities such as arsenals, ports and warehouses."

"The 100 beast-like warships that are supported by the artificial island below are not combat units, and the artificial island will also have a passage to connect with its hatch, which is basically a accommodation area, and at a critical moment, all the personnel will be withdrawn into it, and the artificial island can be evacuated immediately."

“······”

Along the way, Tang Ling continued to explain to Zhang Yuanzhen, from the southern area to the western area, and finally entered the most important northern area of the artificial island.

Stepping into the North District, as a general, Zhang Yuanzhen was immediately attracted by the "luxury" configuration here.

The first thing that caught your eye was the command building that stood tall in the center of the North District, and Zhang Yuanzhen, who had been on the aircraft carrier No. 0521, recognized the origin of this command building at the first time.

"This is the bridge of the aircraft carrier?" Turning around, Zhang Yuanzhen asked.

"Yes, at present, the template in my hand that meets the command command is the bridge of 0521, so I simply copied one directly to the artificial island." Nodding, Tang Ling affirmed Zhang Yuanzhen's guess.

"That..." Hearing this, Zhang Yuanzhen's eyes were already filled with blazing light.

Being looked at by the other party like this, Tang Ling had to continue to speak: "Well, although I don't have the ability to copy all of the entire avionics system at present, this command can also achieve 50% of the functions of the entire avionics system of the 0521 bridge, of course, the air defense system and missile launch system are also equipped here!" ”

"Hahaha, let's go, let's see!" Hearing Tang Ling's words, Zhang Yuanzhen laughed and said, and then rushed into the headquarters building in a hurry.

Zhou Tianbao, who came to the command room and was still here to make the final debugging of the equipment, personally opened all the weapon systems arranged in the northern area for Zhang Yuanzhen.
