The strongest commander in the last days

Chapter 298

It has been more than 50 years since the hydrogen-oxygen engine was invented, and its application technology has become very sophisticated. Moon landings, satellites, manned spaceflight, etc. are all inseparable from the hydrogen-oxygen engine.This is also the fuel with the highest specific impulse currently used by humans.

The specific impulse can be understood as how many seconds a rocket engine can use one kilogram of fuel to produce one kilogram of thrust, and the specific impulse of a liquid rocket is as high as 450 seconds.

If it is not intuitive enough, it can also be expressed in terms of power generation. For example, one kilogram of coal generates 8 degrees, one kilogram of diesel generates 11 degrees, and hydrogen fuel is as high as 35 degrees.
In other words, one kilogram of hydrogen fuel is enough to rival three kilograms of aviation kerosene!However, liquid hydrogen fuel is extremely unstable, and there is a risk of explosion if you are not careful. This is a test for the various structures of the aircraft, so there is no large-scale application.

But these are rubbish compared to Zhang Wei's nuclear fission battery, which contains only ten grams of 2.25% uranium-235.But these ten grams are enough to generate 4500 degrees.

Due to utilization efficiency issues, actual power generation is about 300 degrees per gram, which is still comparable to 40 kilograms of coal, 30 kilograms of aviation kerosene, or 10 kilograms of hydrogen fuel.

Handing over the plane to the scholar duo, Zhang Wei escorted 500 laborers away from the airport.Before leaving, Zhang Wei also explained that this plane can be lent to you for three days. During these three days, you can make any fuss, but after three days, I will take back the leftovers.

I believe that whether it is avionics, radar, disturbing equipment, titanium alloy hull, carburized armor... these two experts can do enough research.

There are tens of thousands of people in Yundian, but they are all low-educated people from Southeast Asia, and there is also a language barrier.It will be some time before the 1003 people arrive from the 4000 gathering place, and there is still a huge population gap in Zhongyi City.

Naturally, this part has to be entrusted to General Blood Fury. Zhang Wei paid [-] yuan as soon as he asked, so he didn't spit blood out of Liu Feifei's scare.

As soon as Zhang Wei returned to Zhongyi City, he saw an acquaintance, or a dog.

"Rhubarb, are you back?"

"Commander, as soon as I heard that you were commanding our dog clan, I rushed back immediately!"

No wonder the task was inexplicably completed. Rhubarb's attitude determines most of the dogs. It is really not difficult to gather [-] people who are loyal to Zhang Wei.

"Great, many of my plans can be implemented with you back. The prosperity of the dog clan is inevitable! I currently have many plans. I want to build Zhongyi City into a world-class gathering place for intelligent races, so that all intelligent races can All can live in harmony with humans!"

"Hey, I'm afraid it's just wishful thinking on your part. Can you and Rhubarb represent the ethnic group? Fusion is impossible, and only fighting is the eternal theme!" A spy's voice came, with a rather harsh tone.

"Um...this is the speech of the second grader."

At the stall where Rhubarb was being moved, it was like a pot of cold water was poured on the heart, the anger was burning in an instant, and turning around was a big slap in the face.

"What are you daring to speak here? Did I let you speak?"

The owner of the shrill voice fell down in response. Thick hair was exposed under the mask. He was obviously not human.Dahuang's good temper has always been directed only towards humans, and he can be said to be a staunch racist.

The guy with the furry face stood up and put on his mask, remaining silent.

"Commander, let me introduce to you, there are still many intelligent species in this world besides our intelligent dog family. Among them, there are only seven that have become mature."

Salamanders, belonging to the amphibians, have twin waterways, hairless and scaleless.Although they are twins, one cannot live on land for a long time, and the other cannot breathe underwater.Therefore, most of the clan are super masters, who have a unique ability to control water.

The Wing Clan was originally a variety of birds, but because the birds are rare and intelligent, they are similar, so they are grouped together.Among them, the smallest volume is also poultry, and the larger the group, the easier it is for wisdom to appear.For example, ostriches, cranes, eagles, etc. are the bulk of the number.

Chiropods, commonly known as bats, are beasts that can truly fly.The intelligent ones not only restored their eyesight, but did not lose their hearing.The myth of listening to sound.And most bats don't drink blood, especially the intelligent bat race.

Pilin tribe, mammals wearing heavy armor, the prototype is probably a branch of pangolin.Most of the people in the clan are tall and tall, with a certain ability to divide rocks into three soils, somewhat similar to Shi Lei.

The hoof-horned family, the prototypes are mostly horned creatures such as Perissodactyla and Artiodactyla, and the prototype of horses is also included in it.After being intelligent, she is still a staunch vegetarian, but her aggression has greatly increased.The group has excellent stamina and a huge appetite.

The big cat family refers to various large cats, such as cheetahs, leopards, black panthers, etc., as well as lions and tigers, not domestic cats.Most of this group has thick fur, and is good at perception, responsiveness, and excellent eyesight.

The Bear Clan, the single king, dominates the world.After becoming intelligent, he is still a giant man nearly three meters tall, but his intelligence level is slightly lower.

These seven major races, plus the dog race, occupy the majority of intelligent creatures, and they are unique in both quantity and strength.

"Human, is it true that you just said that you want to build a city? Coexist with us and other intelligent races?"

Da Huang anxiously said: "Loyalty City belongs to my dog ​​clan, what are you talking about? Weird!"

"Old dog, that's not what you said when you wooed us. Don't think that just because you are close to humans can distort right and wrong. We are here to seek cooperation, not to recognize the master!"

"My clan has always been scattered. I don't know if we can adapt to living together."

"What's the benefit of cooperating with humans?"

Zhang Wei waved his hand to stop everyone's discussion, and then said: "Everyone, you are right to seek a shared apartment. Whether you recognize the owner or not depends solely on your will. Zhongyi City has been built not long ago, and you should be able to see the living standards!"

"The dog race is close to humans, how can you ensure that we are treated the same?"

Zhang Wei grinned and said, "It's normal for dogs to be treated well, why do you think so?"

Dahuang puffed up his chest unconsciously, and many representatives of intelligent races had question marks on their faces.

"Everyone, I think you all know the time of the moon, and the intuition of beasts will not lie to you. What I want to say now is that there are ways to cooperate, and there are benefits to recognizing the master.

The dog family is dominated by humans. Is there anything wrong with humans spending money to raise dogs?Since you are self-reliant and self-reliant, how can you be so embarrassed to ask for benefits from human beings?If humans give charity, wouldn’t they look down on everyone here? "

"Oh? Then what do you want?"

"Since it is a refuge where we all live together, you all must work together to mobilize your clansmen to build Zhongyi City!"

The shrill voice just said abruptly: "There is only one question now, how sure are you guys going to survive this catastrophe? If the number of days is doomed, how can you humans turn the tide?"
