In the small space, the outside announcement sù Tianming a bad news that made him feel bad.

In the past few days, from morning to night, there has been a black shadow moving back and forth above the small space, dangling, and now the black shadow is not moving, just stopping somewhere in the dome of the small space and not moving, leaving a small black dot, which is very conspicuous.

Tianming walked over to take a look, and was also startled, and quickly took out the "Tianming No. 2" shell spaceship, blew open the space barrier with the 'rebound' rune, and came to the outside of the small space.

One, two, three, four, the wreckage of a total of four shell ships.

Except for the spaceship docked on the barrier above the small space, the wreckage of the other three spaceships was found within 1oo kilometers of Tianming.

Throwing away the charred corpses and putting the wreckage of the four ships into the ability space, Tianming returned to the small space.

Except for the spaceship parked above the small space barrier, there are no space boxes in the other spaceships. This made Tianming wonder if those aliens wanted to occupy a small space, or did they want to cut down the giant sequoia tree? Anyway, once they come in, it must be a matter of life and death.

"Grandpa, it's not safe in a small space now, or I'll send you outside." Tianming is fair to the outside world.

My grandfather has changed his appearance now than when he first came in, his head is as silver as snow, his beard has become very long, he walks without hurry or slow, and he looks like a fairy wind and bones. Acquaintances will definitely not be able to recognize it anymore when they see it, and even Tianming feels that his grandfather is almost the same as before.

Usually when the morning is not in the small space, my grandfather will do his own laundry and cooking, sometimes come back from a walk outside, the body is tired, hungry, casually eat two handfuls of red fruit and yellow dates, and the day will pass.

Liu Shengzu waved his hand, "No need, it's good here." It doesn't matter if it's dangerous, I'm an old man and I'm still afraid of aliens? ”

There was no way, Tianming could only call the golden melon seeds and silver melon seeds over, and even the little gray gray called over, telling them: "When I am not there, you must protect your grandfather, if something happens to him, you will be fine, I will make you look good!" ”

After understanding Tianming's meaning, the golden melon seeds nodded, and the little gray gray also leaned closer to his grandfather. It has the meaning of close guard.

……

It's time to find a way to address the threat of Blue Mercury.

First of all, Tianming needs to build a big ship, at least a big ship the size of an aircraft carrier, otherwise it will not be able to withstand the strong winds and waves on the surface of the Blue Mercury Sea, let alone control that planet.

The materials for shipbuilding have accumulated to several thousand tons, and in a while they will break 10,000 tons.

Among these materials, there are not only more than 3,000 tons of titanium alloys, but also aluminum, steel, ceramic materials and some lightweight composite materials, with hundreds of types. There are no problems in creating a heavy destroyer.

Moreover, in the process of material research, Tianming has emerged two kinds of materials with heavy dà significance.

Both of these materials were brought by him from Blue Mercury. are two metal ores.

One is black ore and one is silver ore.

The black ore was named "Black Iron" by him, and the silver ore was named "Silver Steel" by him.

Black iron ore has a complex structure, and 7o% of the composition is metal alloys such as iron, cobalt, nickel, and manganese. The composition of the other 3o% is very complex, mostly inorganic compounds and metal salts. But the physical properties are quite good, with high strength and good toughness. It's about 1.5 times that of steel.

He has more than 3oo pieces of black iron ore in his hands, which weigh about 4,5 tons.

The silver ore surprised Tianming.

The ore is made up of an unknown metallic element with an extremely high purity, reaching 96%, but with a very low density of 2.73, only one-third of that of ordinary steel.

Silver steel is about 6 times stronger than black iron, and the toughness of the drawn wire is comparable to that of carbon fiber. What's more, when Tianming used a laser to burn his silver steel, the temperature reached 55oo degrees, and the metal began to melt, and the ability to withstand high temperatures was amazing!

After some investigation of the internal atomic structure of this metal, the reason for this was revealed.

Inside this metal atom, there is a special electron that moves around the nucleus, which is larger than ordinary electrons, and Tianming captured several and conducted some tests, and finally confirmed that the carrying charge of this electron is 3 EV.

So, he named this electron "strong electron".

The presence of strong electrons makes it easy to explain the physical properties of this metal. Under the movement of strong electrons, countless atomic nuclei are tightly bonded together, forming a hard, tough, corrosion-resistant, high-temperature resistant magical metal. The physical characteristics of this metal are far more than any kind of metal on the earth, and the density is very low.

If this metal is used to build airplanes, tanks, rockets, and aircraft carriers, how strong will the defense and mobility become?

After a detailed exploration of the black iron ore, a very small number of strong electrons were also found in Tianming, which also proved that the strength of black iron is stronger than that of steel, and it is also because of this strong electron at work.

Because he had seen the steel battleships of the Blue Star people before, how did he realize the two types of battleships of black iron and silver steel that the Blue Star people made? I don't know, maybe they have rune technology, and they have already figured out how to forge these two metals.

The problem is to return to the issue of shipbuilding, Tianming's plan is to build a large aircraft carrier, this kind of aircraft carrier, at least 33o meters long, 7o meters wide, 5o meters high, draft depth of about 1o meters, with a wide deck, towering ship islands, large tonnage, imitation of the template, is the Nimitz-class aircraft carrier of the United States.

But it is simply impossible for one person to build such a huge aircraft carrier, which will take tens of thousands of people and years to build. Even if you can, it will take a lot of time.

……

Tianming came to the Blue Shield Bureau.

Jiang Pingyang, director of the Blue Shield Bureau, warmly received Tianming.

"Xiao Xu, those radar chips you made last time are very easy to use, and the performance is very high, after our Aegis ship is replaced, the radar performance has increased by nearly half, we really thank you so much!" Director Jiang took Tianming's hand and thanked him.

"It's a trivial matter, no thanks." Tianming smiled and took the tea that Director Jiang handed to him.

"Xiao Xu. You rarely come to the Blue Shield Bureau, so why are you here today? ”

"It's okay, I just want to come over and have a look, Lao Jiang, you take me to inspect and inspect."

"Okay, no problem!" Director Jiang said excitedly.

Among the six departments of the six shields of national defense, the most capable people go to the Heavenly Shield Bureau and the Cyber Shield Bureau, although they occasionally go to the Dragon Shield Bureau to assist in opening a few conceptual weapons, but most of the time, they either go to the Heavenly Shield Bureau to change their motivations, or play games in the Cyber Shield Bureau. Other departments. They've been there almost once, and if they have any problems to solve, they can only come to the door in person.

The more times and the longer the time for the supernatural person to go to that department, the greater the benefit of that department, this is the consensus. Just look at Luo Donglei's chrysanthemum face, and then go to the Netshield Bureau to play a few virtual games, while they are envious, they also hope that the supernatural will come and go often.

Although he didn't know what the purpose of the Stranger came to the Blue Shield Bureau, Jiang Pingyang was still very happy. Took Tianming to visit the various departments of the Blue Shield Bureau.

As soon as you step into the ship design room, you know you've come to the right place.

He said to Director Jiang: "Old Jiang, can you design an aircraft carrier in this ship design office?" ”

"Aircraft carriers?" Jiang Pingyang said in surprise: "Designing an aircraft carrier? This is not our main specialty. Aircraft carriers are designed by specialized design schools, and our design office only studies the construction of some ships. ”

"If you can study it, you must be able to design it, right? Do you have any professional ship designers here? The more powerful kind, I have a few questions I want to ask him. ”

Seeing that Tianming was very interested, Jiang Pingyang called a man with glasses in his thirties.

"Is there something wrong with me from the director?" The man said reluctantly.

He is designing a subversive warship. At the critical moment, he was interrupted from his train of thought, if this person was not the director, he would have scolded him out a long time ago.

"Wu Ke. This is Xiao Xu, he wants to ask you a few questions. Director Jiang introduced Tianming to him.

"Oh, Xiao Xu, if you have any questions, tell me quickly, and I'll tell you the answer right away." Wu Ke said impatiently.

The sharp-eyed Tianming saw what was displayed on his computer screen, walked over and said in surprise: "You still use Maya to design warships?" That's amazing! What is this warship you designed? ”

Wu Ke saw that Tianming was so curious, and praised him for his strength, so he was happy, pointed to the design and explained to him: "This is the electromagnetic cannon giant ship that our country has commissioned fifty years later, and it can be equipped with 6 55omm caliber level electromagnetic guns, as well as 16 22omm small electromagnetic guns. At the very top, an 18omm laser cannon with a movable barrel can be installed to destroy satellites in space if necessary......"

Tianming took a look, isn't this the electromagnetic version of the big ship cannon? In the era of flying missiles, you still play giant ship artillery? This guy must be an avid fan of big ships and giant guns, but his design ability is still good, and the design drawings are very beautiful, much better than his own three-legged cat level.

"En, it's very powerful, we will definitely be able to build such a warship." Tianming nodded for a while, until Wu Ke asked him if he had any questions to ask, Tianming said: "If I list some available materials, such as titanium alloy, steel, wood, etc., can you help me design an aircraft carrier?" ”

"Aircraft carriers? What do you want an aircraft carrier for? Wu Ke said puzzled.

"Don't ask me what I'm going to do with the aircraft carrier, you just say can you design it?"

Director Jiang said to himself just now that this Wu Ke is the most outstanding designer in the design institute, and there is absolutely no problem in asking him to design things.

"Yes, but why should I help you design it? Who are you? Wu Ke was very unimpressed with the young man in front of him.

Director Jiang hurriedly shouted at him: "Wu Ke! He is now your superior, and you can design whatever he tells you to design, what nonsense! ”

"What superior? He is ......" Wu Ke suddenly remembered some rumors in the base, combined with the director's attitude towards him, a thunderbolt flashed in his mind!

"Okay, no problem, I promise to complete the task!" Wu Ke patted his chest and said.

……

On February 25th, an important person came to the National Defense Six Shields, and the atmosphere of the entire base became warm and tense.
