Video spoilers history, starting with the blitzkrieg on Poland

Outside the sky.

Northern Song Dynasty.

Shen Kuo saw that Sirius, which he often observed, was on the list.

It's not surprising at all.

After all, Sirius is so bright, which means it is probably not too far away.

"I didn't expect Sirius wasn't actually a star."

"But two stars?"

"It's amazing!"

"Could it be that in the universe, stars as unique as the sun are actually only a minority?"

"Most star systems actually have more than two stars."

"Wouldn't it be very lively and hot?"

"There is no two suns in the sky, but there are two suns in those galaxies."

"Then if there are aliens on Sirius, wouldn't they have two emperors?"

Shen Kuo was daydreaming with divergent thoughts.

Smiling from time to time is a kind of full satisfaction and pleasure gained from knowledge.

"And I noticed that most of the neighbors mentioned by Tianmu don't seem to be as big as the sun."

"Does that mean our sun is the most important person on Earth and in the universe? Haha."

……

And the sky continues.

[Ranked sixth is UV Cetus. ]

[It is also a binary star system, with a mass of only 10% of the Sun, a diameter of 14% of the Sun, and a surface temperature of 2400 degrees. ]

[And the companion star is about the same size.]

[The two stars are very similar in mass and volume to each other, and can be said to be twin brothers. ]

[This is also the closest binary star system to our sun. ]

【Ranked seventh is Ross with 154. 】

[This is a young red dwarf star, less than a billion years old. ]

[The mass is about 17% of the sun, and the diameter is 24%. Table]

【Surface temperature 2800 degrees. 】

[The distance from the sun is 9.68 light years, which is also impossible to observe with the naked eye. ]

[However, it is expected that the star will reach a perihelion in 15 years.]

[By then, the distance from us will be only about 6.13 light years. ]

[Except for the above 11 stars, all are within 10 light years of the Sun. ]

[Other neighboring stars are basically within 10 to 12 light years of the solar system.]

[According to current observations, there are a total of 12 stellar neighbors within 30 light years of the solar system.]

【20 stars in 30 star systems. 】

[Most of them are red dwarfs, reaching 19. ]

[There are only 7 stars visible to us humans on Earth. ]

[Among these 30 neighboring stars, only two are larger in size and mass than the sun, namely Sirius and Procyon. ]

[As you can see, there are more than 30 stars in just one local interstellar cloud, in this same small area.]

【That’s how many neighbors we have. 】

[So overall, our sun is not alone.]

[So if one day the sun gets old and humans need to move the earth away, which neighbor will you choose as your next target? ]

The sky screen video ended here, and barrages of comments flew out one after another.

"First, we should rule out Proxima Centauri. Although it is close, it is unstable."

"It's better to stay in the sun. By the time the sun stops working, humans will have died."

"I'm not afraid of the sun being too lonely, I'm just afraid of the sun visiting me."

"It's all because Jupiter is not as good as the solar system, which is also a binary star system."

"It's better to be alone. Too much noise is unbearable."

《Binary star systems are actually quite stable.》

"If you like lively places, move to the center of the Milky Way. It is full of heavyweight old stars and various gamma-ray bursts that will make you feel refreshed."

"Why are most of the sun's neighbors smaller than the sun? How shameful!"

"The Sun is considered to be the most massive star."

"Hot Knowledge: The mass of the sun exceeds that of about 80% of the stars in the universe."...

As one of the ancient astronomers, Shen Kuo also felt that he gained a lot from this sky video.

"The sun's neighbors seem very close."

“But it’s still out of reach.”

"Even though the technology of later generations is so advanced, I'm afraid it's still impossible to visit any of our neighbors."

“But this skydome video is pretty good.”

"At least I know why Sirius is so bright, right?"

Soon, a new sky appeared.

Amidst a burst of tense and rapid music, familiar World War II scenes appeared on the screen.

【Operation Bagration during the Great Patriotic War.】

The first thing that appeared on the screen was a military train loaded with many tanks.

As well as various supporting military equipment and personnel around it.

[Late at night, the railway station was heavily guarded, and a new tank unit arrived at the scene.]

[A large number of T34 tanks and various military equipment were unloaded from the platform. ]

[The Soviet army's plan to assemble in the Belarus region is top secret.]

[A few days later, these secret equipment also appeared on the training ground, and their functions were immediately exposed.]

[You can see that the modified T34 tank is pushing the heavy metal barrel forward. ]

[These tanks were called minesweepers by the soldiers.]

[When the minesweeper tanks advanced, the mines buried underground were immediately detonated, clearing the way for the follow-up troops.]

[The 1st Belorussian Front was responsible for protecting two engineering tank regiments.]

[These top-secret mine-clearing tanks are used during offensive operations.]

[The secret was kept so well that to outsiders it looked as if the Soviet troops in Belarus were preparing for defense.]

【Based on publicly available information. 】

[Every move of the Soviet troops in the Belarus region told the enemy that the Soviet troops there had been weakened and that they were prepared to defend tenaciously. The main direction of the attack was elsewhere.]

[On June 1944, 6, the day the Western Allies landed in Normandy, Stalin contacted Churchill.]

【According to the results of the Tehran Conference, the Soviet summer offensive will also be launched in an important area of ​​the front line.】

[In previous years, summer was always the season when the German army was active, but this time it was the Soviet army's turn to attack.]

【Everyone knew that the Soviets would launch a large-scale offensive in response to the Normandy landings.】

[But even the highest-ranking Allied generals did not know where the Soviets would attack.]

……

Outside the sky.

Huo Qubing frowned and looked at the strategic map on the sky.

can be seen,

Germany's situation was very unfavorable at this time.

Italy, the ally on the southern front, had collapsed. The German army and part of the Italian army were on the defensive and could only hold up the situation in northern Italy.

The landings were made on the Western Front, and the French occupation zone was in danger.

On the Eastern Front, millions of Soviet troops were ready to go.

Even Huo Qubing, who greatly admired the German army in World War II, felt desperate when he saw this strategic map.

I could only sigh and say:

"The situation is hopeless, the situation is hopeless. I'm afraid the German army can no longer turn the tide."

"Next, I'm afraid it will be a repeat of the previous Soviet counterattacks."

"Although the German army fought very beautifully and showed the bloodiness and style of the army, it was still unable to resist the Soviet army's comprehensive attack from many directions."

"In the end, we can only choose to retreat after holding on for a period of time."

Huo Qubing made his guess based on the consistent style of previous battles between the Soviet Union and Germany.

Also watching the sky curtain with Huo Qubing was Emperor Wu of Han, Liu Che.

The idea is more direct.

"I'm afraid this time, it won't be that simple."

"After several years of war and a series of failed battles."

"I'm afraid the Germans have reached their breaking point."

"At this time, the Soviets launched another large-scale offensive, and the Allied forces in the west were also attacking, so the German army could not take care of both sides."

"A total collapse is possible." (End of this chapter)
