Although he found the entrance of the spaceship, the gentleman did not stand under the dangerous wall, and the cautious Ye Fei did not mean to enter the spaceship, but stayed with the wolf cub outside the exit and the mountain.

The ship's outer shell and thick rock formations blocked the radio waves, and the two of them had to wait patiently for the drone's feedback.

Aren't drones and robots invented to replace humans in dangerous work?

More than a dozen drones probed a spaceship with a length of more than four kilometers, and the efficiency was outrageously slow, Ye Fei simply contacted the black bear again, and the black bear sent all the remaining drones on the assault ship into the cave.

After more than 300 drones entered the cave, they lined up under Ye Fei's control, and soon gained a foothold in all corners of the spaceship, because the number of drones was enough, and the number of parts in the ship was passed through the transfer of drones layer by layer, and they were successfully delivered to Ye Fei and the wolf cub's armor.

A digital model of the ship's interior takes shape in the armor.

"The shell is too thin, isn't it?" The wolf cub said suspiciously.

The first thing that appeared in front of the two of them was the upper deck of the ship, and Tong Guò measured the distance between the outside world and the upper deck and found that the outer shell of the spaceship, that is, the outer armor, was only 60 centimeters thick!

This thickness is simply too low, for comparison, the multi-layer composite armor of the warships of the Republic is more than a kilometer thick, and the shells of ordinary civilian ships are also three to five meters thick, which is not at all on the same level.

Ye Fei said approvingly: "It's really a little wrong, can such a thin hull withstand the pressure of flying faster than light?" Cut some off for a while and take them back. This hull material may be stronger than our armor. ”

It is not that the thicker the armor, the higher the strength, its mechanical strength also has a very important relationship with the material itself, if the strength of the hull material of this ship far exceeds the armor material currently used by the Republic, then as long as the military successfully replicates the hull material, it can immediately increase the overall strength of the fleet by several steps.

The thickness of armor of the same strength is reduced by two-thirds, which means that the battleship can increase its defense capability by three times while the armor thickness remains the same, or it can reduce the thickness of the armor by two-thirds, but the level of defense remains the same.

The latter can expand the internal space of the battleship by one to one-third, and is able to carry more weapons and provisions. It can also reduce the size of the battleship by a quarter to a fifth. Indirectly increase the maneuverability of the warship.

Battleships are the concentrated embodiment of the industrial level of scientific and technological civilization, and materials are the most important foundation in the manufacturing industry.

If it weren't for the fact that materials have such an important position in the industry, how could Ye Fei have fought hard in the middle of the way and Yaren for the sake of super alloy?

Thinking of this, Ye Fei's heart was hot.

But he also knew it. At the level of human technology. It's easy to figure out the composition of metal materials. However, it is difficult to replicate, especially for alloys, where the purity of the raw material does not meet the requirements. Timing and sequencing issues can cause the finished product to fall short of the design standards.

It has been several years since the super alloy fell into the hands of humans, and if it weren't for the fact that it was too difficult to copy the alloy, the new warships would have been replaced with super alloy armor long ago, how could they still use the old ones of the past like now?

"I'll have to ask Bear Boss to send a laser cutter down in a moment." The wolf cub rubbed his hands together and said.

He left the hull and entered the digital model with a controlled perspective, and the "air-tight cabin" that he had just seen appeared in front of his eyes, and continued to move out of the air-tight cabin, and the upper deck came into the sight of the two.

"It's empty." Ye Fei muttered in a low voice.

The deck outside the airtight cabin was empty, and the only building that could be seen as far as the eye could see was the airtight cabin behind it.

The wolf cub gasped again and again: "Why do I feel so bored when I stay in this hellish place?" ”

"Can you not get bored!" Ye Fei looked up, "This ceiling is two meters high at most. ”

Although the two did not actually enter the interior of the spaceship, the digital model can realistically reproduce the qiē inside the spaceship, which can give people the feeling of being there.

"No wonder." The wolf cub suddenly realized, looked up at the mottled ceiling, then looked down at the stale deck, and said, "This place is really old." ”

"Can it not be old, I don't know how many years it has been here." Ye Fei changed the angle of the digital model and transformed the reality into a floor plan, only to find that the spacecraft actually used an all-through upper deck.

At regular intervals on the deck, there is an airtight compartment that leads to the outside world between the deck and the hull, as well as several extremely thick metal columns, presumably the keel of the ship.

For ships sailing on the surface, the keel is only a longitudinal load-bearing member connecting the end and end in the center of the hull base, although it plays a pivotal role in the hull structure, its specific structure is not complicated.

Although the rigid skeleton of a spaceship is called a keel, its structure is more like a scaffolding for construction, which is not the same thing as the keel of a surface ship.

"I'm not talking about the oldness of time, but the oldness of being used for a long time." "Look underneath, the deck is very worn. ”

Ye Fei switched back to the real-life mode and looked down, isn't it, even if the deck is covered with a layer of dust, it can't hide the traces of wear: "You can see it with your eyes!" It seems that this spaceship will take a lot of time. ”

As he spoke, several drones had already outlined most of the upper deck, and Ye Fei suddenly found a few unusual things, the shape was very irregular, and he couldn't help but wonder: "What is this?" As he spoke, the scene in front of him and the wolf cub immediately changed, appearing directly in the vicinity of those strange structures.

I saw that a large hole had been made in the ceiling overhead, and the stone pillar hung down from the hole, and grew into a stone pillar on the deck that was narrow at the top and wide at the bottom.

"Damn, what am I supposed to be?" Ye Fei scolded with tears and laughter.

The wolf cub counted the number of stone pillars on the map and said, "There are eight such pillars on the first deck, that is, there are eight large holes in the hull...... Boss, do you think these holes were smashed out by stones after they were parked here, or were they blown up by the Shang people before they were buried? ”

Ye Fei was silent for a moment and said, "I hope it's the latter." His eyes were fixed on the base of the pillar, trying to find a clue as to if it led to the next deck.

If the stone could be smashed through the hull, it is conceivable what level of the hull material of this spaceship is, and the previous speculation about the hull material has completely turned into a joke. (To be continued......)
