Although Zhou Kuang had been prepared for the difficulties that the renovation project might encounter, the time for the project to come to a standstill was much more than everyone expected.

Because it all came so suddenly.

There is no difficulty in chiseling through the shell, not to mention that the strength of the shell of the biological spaceship is higher than that of the composite armor, but no matter how strong the shell is, it can't withstand the water grinding work of the drop stone, and under the 24-hour uninterrupted cutting of the laser rock drill, it only took two days to cut through the shell more than ten meters thick.

To everyone's surprise, the shell of the biological spaceship was actually divided into more than a dozen layers like composite armor, which was not found on the larvae of the biological spaceship at all.

Zhou Kuang didn't say a word, and immediately recruited the relevant researchers to the dock ship, and the shell cut from the spacecraft was the best research material.

Underneath the hard shell is a buffer layer up to ten meters thick, which has not been found on the larvae, the tissue that makes up the buffer layer is soft and tough, the deeper it goes, the softer the texture of the buffer layer, at first glance it looks a bit similar to rubber, but its strength far exceeds all the high-strength fibers found by humans so far.

The hard shell with an outer layer more than ten meters thick, plus the soft inner lining with an inner layer more than ten meters thick, is a total of nearly thirty meters thick composite shell, even if it is hit by a heavy gun, even if the hard shell is shattered by the strong impact force, it will be absorbed by the soft inner layer and will not endanger the deeper inside.

The veterinarian was amazed and couldn't imagine how the bioship had evolved such a composite structure, in the same way that steel plates were inserted into soft body armor.

The lab has been working on biological spacecraft, but due to the shortage of personnel, most of the current personnel have focused on the internal structure and special organs of the spacecraft, and have not really studied the ship's hull in detail.

In order to ensure that the strength of the shell is not missing, Zhou Kuang can only order to keep the buffer layer.

The buffer layer is a layer of biological tissue, in other words, a bit like a thick layer of tendons, which must be carefully treated to always remain soft, otherwise it will not be long before it becomes dry and hard due to the loss of moisture, or rots due to the multiplication of bacteria.

There is research in the laboratory, but there is no research on embalming, but this time it made Zhou Kuang very sad and had to ask the base for help.

However, for preservation, human means are really lackluster, all the means that can be thought of have been used, but still failed to prevent the decay of the buffer layer, and finally Zhou Kuang had to reluctantly order the removal of the buffer layer, ready to replace it with rubber of the same thickness.

Even if the intensity drops, it's better than nothing.

The impact of the buffer layer is not limited to this, the buffer layer of more than ten meters thick is nothing for a huge biological warship, but it is very troublesome for the engineering design, and the original modification plan must be re-modified to compress the volume of the original design to accommodate the reduced space.

In short, people turn on their backs.

Zhou Kuang was tired of dark circles under his eyes, blisters appeared at the corners of his mouth, and the whole person lost more than a circle.

After solving the buffer layer problem, I ran into trouble again.

With the size of a biological warfare ship, keeping only the outer shell will greatly affect the mechanical strength of the outer shell, and the internal support structure must be retained as well.

The so-called support structure is the bone structure inside the biological spaceship, to put it simply, human beings are flesh and bones, and the bones themselves play a supporting role. The biological spaceship and the outer skeleton are both flesh and bones, and the internal support structure is similar to the load-bearing beam of a building, which can greatly strengthen the shell.

Although the laboratory has a rough grasp of the structure of the biological ship, the biological ship has a large number of bone walls that divide the entire ship into several spaces, but they have nothing to do with the load-bearing structure, and it is not easy to remove the excess parts.

The "construction" team had to figure out which bone walls were supporting structures and which could be cleaned up before they could be removed without destroying the overall strength.

Zhou Kuang's most important thing is the bone strength of the biological spaceship, but for the cleaning personnel, the higher the bone strength of the biological spacecraft, the more troublesome the removal work, and the volume of the high-power laser rock drill is too large, and some positions cannot be used, so they have to make some improvements and install a retractable bald head to barely solve the problem.

Despite the stumbling and troublesome problems, with the concerted efforts of the engineering personnel, the initial clean-up work was finally completed after more than half a month.

At this point, the internal tissues of the bioship were largely cleaned up, leaving only the corners. This was followed by more than 10 days of in-depth cleaning before it was completed. Fortunately, this biological spaceship would have died a long time ago, otherwise even the people of the structure group would not know how to slaughter this behemoth.

By the time the deep cleanup was over, a complete biospacecraft shell appeared outside of the Saturn base.

The rest of the work is not in the hands of the laboratory, and the battleship factory at the Saturn base is very interested in this plan, and at the beginning of the implementation of the plan, a team of designers was sent to understand the shell shape and structure of the biological spacecraft.

In order to save time, designers were asked to use as much equipment as possible for retrofitting.

This is difficult for the designers, the human spacecraft are mostly square, and only a very small yacht of pure entertainment nature will cause streamlining.

There is no air resistance in space, so there is no need for a spaceship to be streamlined, and a square shape is easier to process than a streamlined shape.

The only streamlined battleship is the Giant Whale class.

That's it, or because the Saturn base has built a mega-ton super-large hydraulic press to have the industrial foundation for building a giant whale, without this behemoth, it can only be decomposed into independent small components that are formed in one piece, and then combined after being made.

This is not only time-consuming, but also greatly affects the overall mechanical strength of the component.

For civilian spaceships, this loss of strength is nothing, but for a warship, any slight error may affect the final performance of the battleship.

This is also one of the reasons why China's top leaders are willing to disclose the whale-level drawings to their allies - they lack the necessary industrial base, and no matter how advanced the drawings are, they can only be a flash in the pan.

It is said that the Giant Whale class is a very good prototype, but due to the difference in internal structure, the internal design of the Giant Whale class is completely useless, and can only be used for reference, and then try to recombine in the shell of the biological warship, which is no less difficult than redesigning a new warship.

There was no big trouble on Zhou Kuang's side, and there were constant small problems, which more than doubled the progress of the entire project, which was also wrong, and it happened to leave enough time for the design team.

After the shell was processed, the base immediately sent a tugboat to tow the shell into the dock, ready to carry out a complete transformation, such a huge action, even General Xu Shijie and Xu were alarmed.

The production of human warships has long been automated assembly lines, but in the past, all of them were assembled from the inside out, and there has never been a situation where the equipment is assembled when there is a shell first, and it is a complete shell, and the existing assembly line, no matter how advanced, cannot cope with this situation.

The battleship factory at the Saturn base had no choice but to draw out elite soldiers and start the refit work in three shifts 24 hours a day.

Although the design team took into account the utilization of existing equipment as much as possible, many of the equipment still needed to be redesigned and retrofitted to accommodate the new retrofit work.

In the eyes of Zhou Kuang and the veterinarian, modification is nothing more than stuffing a bunch of ready-made equipment into the shell and fixing it, which is not difficult at all, and many people in the laboratory think so. But they all thought wrong, even if all the equipment was ready-made, it was not that simple, otherwise what else would the designers do?

At the beginning of the design, it is necessary to consider whether the weapon settings of the spacecraft are balanced, and symmetry is the easiest design to achieve balance, because the installation position of the equipment will directly affect the position of the center of gravity of the spacecraft. The center of gravity of the spacecraft must be on the central axis in the front and rear directions, only in this way can the propulsion axis of the thruster run through the center of gravity.

Otherwise, when the ship is built, the propulsion axis will deviate from the center of gravity, and the spacecraft will rotate in circles like a donkey pulling a mill.
