The world of the Romance of the Three Kingdoms, in the universe.

Enterprise, Arden's Spear, Yamato, King Kong, Bismarck, North House, Veneto, Missouri, Essex, Lexington X2, and Peter the Great. There are a total of twelve ship girls, most of which are composed of Li Nan's capital ship mother, and the rest are some powerful ship girls.

After receiving the greeting from the ship's maidens, Li Nan was about to enter the interior of the planet fortress, when he suddenly felt a wave of spatial fluctuations appear on his body, and then received a message from the Enterprise to teleport Li Nan to the inside of the ship's hull.

The next moment, Li Nan appeared on a bridge full of sci-fi atmosphere, and the twelve ship girls who had not been seen for a long time also stood in front of him in a row, although the fusion of the fifth order had passed today, but the aura of these ship girls was almost the same as before.

After the introduction of the enterprise, Li Nan's current location is the control center of the entire planet's fortress, the whole room is in a dim state, and the surrounding space is the position of Li Nan's cosmic space before, and even the planets in the distance that have established bases and are mining can be seen very clearly. And when Li Nan's gaze moves to each target, the corresponding target will be magnified and displayed on the projection device not far in front of Li Nan, and various data can be labeled at the same time. However, the new robot that is working on the planet was made after fusion, but the projection already shows the identification of friendly forces and the specific data of the robot.

"When you came in just now, we got in touch with the Flame Queen of the main base, and we did a database update by the way." As if knowing Li Nan's thoughts, the enterprise number immediately answered Li Nan's questions.

"Okay." Li Nan nodded helplessly, the speed of this database update is a bunker, and this kind of network speed is definitely not stuck. Then he continued: "How is the fusion this time, and your state? ”

At this time, the environment in the room suddenly changed, and the dim cosmic space instantly turned into an ecosphere environment in the bright atmosphere. At the same time, the surrounding area has become a vast grassland, and at the same time, you can see the mountains in the distance, and a wide river on the right-hand side, stretching to the mountains in the distance. At the same time, you can also see that there are many small animals on the grassland, and there are also various fish on the river, and at the same time, Li Nan can also feel a breath of fresh air, these things in front of him are definitely not just projections, Li Nan walked down from his seat, and even stepped directly on the grass.

"This was the surface of the planet at the time of the merger, and when we started to create new ships, we felt that we were going to build an internal ecosystem anyway, and we would simply remodel the entire surface of the planet and then shape a new ecosystem. The biosphere is used as the basis of the entire planetary fortress, and of course, the interior of the planet has also been transformed, but it has been transformed into the foundation that supports the entire outer fortress. The Enterprise began to explain to Li Nan the current situation of the entire planetary fortress's hull: "The rest of the fortress was built on top of the biosphere, and the entire biosphere was surrounded by the fortress in the most central position, so the center of the fortress was also built in the biosphere. The fortress's defense and attack system is only equipped with the generator of the Psionic Shield and the gold fleet in the Arden Spear hangar, and all the rest of the attack and defense weapons are not installed according to the requirements of the Admiral. ”

Well, although the Enterprise has advanced to become a fifth-order ship, but because of Li Nan, there is not even a single air cannon installed in the new hull, but it is not without combat effectiveness, at least her hangar still has a whole golden fleet, and the fifth-order psionic shield cannot be easily broken. Even if he only has such combat power, he will be able to beat the entire fleet before Li Nan's fusion. Of course, the main reason for not deploying weapons and defense systems is that the technology at that time was not very mature, so I felt that even if it was installed, it would be better to install nothing at all. Of course, since the psionic shield is a mature technology of the Star Spirit, this one will be installed first.

As for such a huge planet fortress floating above the cosmic space, it is a live target, so a shield is very necessary. Of course, in fact, the speed of this behemoth in the universe is not slow at all, relying on the force field of gravitational waves so that the planet fortress can easily move in all directions, and even speed up to sub-light speed. At the same time, it can easily move in space within a range of 100,000 light years, and as for ultra-high-speed subspace movement, it can also perform cross-galaxy navigation such as space refraction at the moment of starting.

In just a few moments, the Enterprise only controlled the fortress and teleported back to the vicinity of the main base, and then the main base slowly landed on the top of the planet fortress.

And about the weapons and defense of the current planet fortress, now all kinds of black technology fields have been conquered, compared to the previous fusion of the technology tree has indeed lit up several layers, and these materials are all stored in the database, and just now the enterprise has updated the database, that is to say, these materials have been obtained by the enterprise, then as long as these ships plan a set of suitable weapons for their new hull, and then install the design of the plan to transform, Now that the rest of the ship's mothers have left, only the Enterprise is still with Li Nan, and they are just going to do it. As for why the Enterprise is still here, it is because she has also obtained the information of the ghost power core in the database, so she knows that Li Nan wants her to copy this thing, and she also knows about the Donghuang Bell.

And Li Nan didn't say anything, but directly took out the Donghuang Bell from the storage space, this artifact has established a certain connection with Li Nan, and has also completed the procedure of recognizing the owner, so now the enterprise number is also directly used on it, and at the same time, it also verifies Li Nan's idea, the enterprise number has been copying various equipment, it is by virtue of the power of creation.

Then the Enterprise also took the ghost power core for analysis, and now there is no need to eat things as before, but directly analyze the object, as long as the analysis is completed, it can be copied.

"It takes about 500 million units of nanomatter to replicate a nanomaterial." After a while, the enterprise had completed the analysis of the core of the ghost power, and then directly gave Li Nan a cost. 500 million units of nano matter, this amount is already Li Nan's current hour's output, you must know that this number is definitely a lot, Li Nan now occupies three hundred resource stars for non-stop mining day and night, but fortunately this is still within an acceptable price. However, what gave Li Nan a headache was the power furnace of the five fifth-order warships to be built later, this kind of ghost power furnace composed of twenty ghost energy power cores actually required a high price of 11 billion, that is to say, to complete the remaining fifth-order ships, in addition to the 15 billion resources transformed, nearly 10 billion resources were also needed to manufacture the core power furnace, but as an artifact, this amount of resources is indeed not too expensive. As for the creation of mythic-level resources, Li Nan arranged it immediately after entering the hull, and now it is obvious that some have been built for trial, anyway, it is all the work of the little goblin.

However, it is not an easy job to copy these cores, basically the enterprise number has to concentrate most of the energy, and at the same time assemble the various parts of the power furnace, it took the enterprise number five days to manufacture the first power furnace, and the first attempt is the northern sauce, in addition to the northern sauce, there is also a stronghold Qi Ji, the deep sea battle column of the five empty mother and five steel sea dragon Ji led by O sauce, a total of twelve cores have been completely lit up.

Then when all of these deep-sea ship girls who combined the core were integrated into the core, and then the fusion of the second fifth-order ship girl officially began, and the fusion time was also five years, which was not wrong. Because these are all fleets that have already stocked up on resources early on, the body of the remaining four fifth-order ships is also noticing, and a large number of ships are storing enough resources.

The Enterprise is also very interested in this new power furnace, so it was decided that the current hull already has a solar core, and the addition of a set of higher kinetic energy energy cores can very well distinguish between offensive and defensive weapons can be used at the same time.

At the same time, the previously developed battery was also produced by the enterprise, but of course, this first-level product could not be done by the enterprise itself, but let the goblin directly build a so-called ghost battery production line. This is actually a cubic iron box, and then one side is the entrance of resource delivery, and then the other side is a conveyor belt, after investing a lot of resources, one by one the ghost batteries emitting a faint blue light roll down to the box below through the conveyor belt.

These ghost energy batteries are used to make various energy weapons, and they are installed into various firearms as an energy core, which is intended to be designed for the zero-point sniper rifle, and when the time comes, it will directly connect with the weapon to shoot various ghost energy rays, which are much better than the previous Gauss sniper rifles in terms of speed and power.

At the same time, after the northern sauce began to fuse, the fusion of the next fifth-order ship Niang was also ready to begin, and the third ship Niang, Li Nan chose the Xuanyuan Sword, and then with enough energy strength to attack the battleship, such as the assistance of the battle sister or something, Li Nan planned that this is a ship Niang is a pure high attack ship Niang, is to deal with individual strong enemies, of course, this kind of energy-level attack, she will be the main attack ship Niang under Li Nan at that time.
