"Some of you will embark on a journey that will last for three hundred years, and you will never see your parents again, and you will no longer have any connection to this world.

The military will give your family a generous subsidy, as well as the honor of a hero, so that you don't have any worries.

If the Earth is not destroyed, we will send a light-speed spaceship to welcome you back and enjoy the treatment of heroes, if the Earth is destroyed, all you need to do,

It is as a spark, the last hope of mankind, to continue our civilization in another world, so tell me loudly, you are not afraid! ”

"Don't be afraid! Willing to sacrifice his life for the continuation of Chinese civilization! The 300 officers and soldiers in the audience shouted in unison, and the sound resounded through the sky.

"If you voluntarily sign up, step forward!" Tang Xue looked at them full of enthusiasm and shouted.

"Smack."

Everyone stepped forward in order, and from the moment they stepped into the barracks, they decided to give their lives at any time.

They were able to come here, not for themselves, but for the thousands of people behind them.

Whether it is the disaster of the day of the natural disaster or the destruction of Tokyo to rubble, it shows that the world is not at peace.

In the midst of danger, there is no shortage of people who are willing to sacrifice their lives for the ideals in their hearts.

"Whoever of you is the only son, step back!" Tang Xue glanced at everyone present, but no one retreated.

"I repeat, an only child, take a step back!" Tang Xue had to raise her voice, but everyone was still unmoved.

"Liang Wu! Qinshan! Xu Zhou! Are you not only begotten! Tang Xue walked in front of several people and asked.

"Report Chief! We are not only children! ”

"Tell me out loud, you are!"

"We're not!" The three whose names were read shouted in unison.

Tang Xue patted the shoulders of the three of them and walked to the front of the team.

"I know every one of you wants to go, but right now we only have one Tinder spaceship, so the number of places this time is limited, tomorrow morning at seven o'clock,

A three-day selection is underway, and after passing the selection, you have no room for regrets, do you accept it?! Tang Xue asked again.

"Accept!" The three hundred people present shouted in unison again.

"Okay, now listen to my command and go back to the camp to rest!"

"Yes!"

.....

The next day, at this airbase, a vigorous selection began.

At the same time, Datang Technology headquarters. 110 eBooks

After the grand annual meeting, the employees all took the transport plane of Datang Technology and returned to their respective homes.

To be honest, when such a large transport plane was flying all over the country, it still caused a great sensation, but when they saw the name of Datang Technology, everyone was relieved.

However, when the employees took out the magic potion and the holographic projection phone, it immediately set off a craze on the Internet.

Even many rich people began to secretly inquire about the news of this super potion, because rich people always spare their lives.

Some rich generations have worked hard for most of their lives, and their bodies have already fallen into a lot of dark diseases, most of which have no way to seek medical treatment, and they have to go into the coffin with their diseases.

When they inquired about this medicine, in addition to secretly exploring the wind of Datang Technology, they also spent a lot of money to buy the medicine from the employees.

A potion was actually bought by a rich man for a high price of three million, and the employees and the rich man were happy.

It's just that in two months, when this medicine is officially sold online after the New Year, the rich man must not be able to laugh.

Ye Fan didn't care about these things, after all, the medicine that had been sent out, how the employees liked to sell it, buy early and enjoy it early, and buy late to enjoy the discount.

He is following the drawings submitted to him by the end of the year in accordance with the space development department, and let the origin re-optimize the drawings.

I saw a drawing of a space battleship displayed on the holographic projection.

Unlike the composure and majesty of the "Jade Emperor"-class space battleships, the drawings show a brand new series of battleships, and they are armed to the teeth.

If the "Jade Emperor" class space battleship is a relatively balanced battleship, then this new battleship is focused on firepower output, just like "lack of firepower phobia", everything is considered for the purpose of maximizing output.

In the future space war, the possibility of large ships and huge cannons is actually very small, but the possibility of small ships and cannons is increasing.

After all, there is an artifact phenomenon in the universe called the square cube law, an object is scaled in equal proportions, and its volume will be amplified by the square relationship of length, and the volume and mass are amplified by the square relationship.

When it comes to weapons and equipment on the earth, what is most constrained by this law is actually the resistance and the volume of weapons and equipment.

Because under the same shape, the drag is directly proportional to the front surface area, but the mass of the weapon increases in a cubic relationship as the size of the weapon increases.

In other words, the larger the size of the weapon, the less acceleration the drag brings to the weapon, and the less the impact on the weapon, which is reflected in ships, aircraft and artillery shells.

This is why the range of a 155mm shell with an initial velocity of 900ms will be dozens of times that of the M16 rifle.

In the same way, the one that flies the farthest must be a large aircraft, and the one that runs the fastest with a full tank of fuel must be a large warship.

The Iowa-class battleship has a full load displacement of 55,710 tons and a full fuel weight of 8,765 tons, accounting for less than 20% of the weight, but it can run more than 20,000 nautical miles in 14 knots.

In contrast, the small destroyers of the same period could only run a few thousand nautical miles under this fuel ratio, and the seaworthiness of the small ships was not as good as that of the large ships, and the stability would be much worse, so it was impossible to fight an ocean-going naval battle with a bunch of shallow water heavy artillery.

It's just that there are also things on the earth that are not very governed by this law, that is, tanks, after all, on the one hand, they do not require much endurance, and on the other hand, the shape and speed of tanks are not very worthy of talking about drag coefficients.

Therefore, many turret tanks were judged to be heretics during World War II, but the turret dual main guns only appeared in the game, which was more dispersed and deployed, and also reduced the battle damage after being hit.

In the case of space, the last one is often more likely, because there is no resistance in space, and the endurance of large ships and small boats depends on the growth of their speed.

It's like the formula dv=v0ln (momk).
