Wan Youfa reminded in the group: There is a strange movement on the other side of the deep ditch, and the speed at which the centipede returns to its nest seems to have accelerated.

Dr. Yao's speech: I just calculated that this planet will enter a year-long period of low light, and for most creatures on this planet, the light level is similar to the dark polar night.

Yao Fei'er didn't explain too much in that group, but talked about the details in her own small group, and attached a 3D simulated planet operation map.

The audience in the 369 live broadcast room couldn't help but post a barrage of praise after seeing the 3D simulated planet operation map:

[I didn't expect such technology to exist in that era?] ]

[Of course, although many of them are not directly observed, but are modeled by calculations, but they are very intuitive and more convenient than making physical models.] ]

[Dr. Yao seems to have used AI-assisted computing and modeling.] ]

[I thought that the AI efficiency of that era was very low, but it seemed that it was a division of people, and the results of smart people were quite good.] ]

[A little worried about the broadcaster, their location happens to be in the polar night area, and they won't see the light for the next few dozen days.] ]

[Not completely devoid of light, there is still some reflected light, but it's far worse than when the dim sun over there illuminates it.] ]

[The environment is different between day and night, and I calculated according to those data references, and the time of the polar night in that area may be more than three years, which is a bit conservative to say that one year.] At that time, the planetary equation did not take into account the borrowing of concepts such as dark matter declination, and there was a large error. ]

[With so many parameters missing, Dr. Yao can still calculate the polar night area for more than a year, which is definitely beyond the wisdom of ordinary people.] The broadcaster is so lucky to have such a teammate. ]

[I would say that such luck also has a huge side effect, such as the streamer is one of the poorest players I've ever met, not one of them.] ]

Li Sa doesn't have much knowledge of astronomy, but fortunately, the simulation diagram is simple and easy to understand, and you don't need to understand astronomical terms or understand deduction formulas, just look at the results.

Li Sa saw the orbital relationship between the sphere representing the planet they were on and the two glowing stars.

These two stars are surrounded not only by this planet, but also by several gaseous planets that are much larger than this one. One of the gas planets is close to the size of a faint star and also has a strong gravitational pull.

When the planet they are on enters the area near this large gas planet, it will be affected for a long time, and one side will be shrouded in the shadow of the gas planet for a long time and will not be able to break free. The sun that emits the strong light will be repeatedly obscured during this time, and the dim sun will also turn into a crescent moon, and the illumination will be greatly reduced compared to the current one.

Their location is clearly marked on a 3D simulated planet, and it takes about a year or so to break free from the shadows. Although several other places on this planet may still be in the Light Zone at first, they will have to go through a period of polar night of ten or twenty days sooner or later, and nowhere can they escape.

No wonder, if you only stand on the surface of the planet and think, ordinary people would never have imagined that such a disaster would happen. Fortunately, Dr. Yao, who has high-altitude detection skills, is also proficient in physical calculations, and as long as there are signs of this problem, she can follow the clues to calculate the results.

Li Sa vaguely felt that something was wrong, and asked in a small group of his team: Since the polar night is about to usher in for so long, why is the thousand-legged giant centipede in a hurry to transport the supplies back to the ground?

Yao Fei'er explained: The surface temperature drops dramatically, the vegetation withers and dies, and the underground nests will be warmer.

The last world of Li Tianya was considered to have experienced the era of interstellar immigration, and the brain hole was bigger, adding: Also, shouldn't the insects and beasts that really like the polar night become active? Those insects and beasts are not dealing with this thousand-legged giant centipede?

Li Sa hurriedly flipped through the illustrated book, and took screenshots of the introduction of insects and beasts that like dark and cold environments and sent them to the team group, so that they could take the time to study which ones could be used as ingredients. Even if they hide in the spaceship, they can still imagine that insects and beasts can roast meat to improve their lives.

In the face of the impending disaster, most players on the surface of the planet are unaware, and some people may have subtle perceptions, will be faintly afraid, and subconsciously look for a safe place to survive.

Only Li Sa and their team have found a reliable survival point, and they are actively planning to close the door and eat barbecue comfortably in the future.

The people in the 369 live broadcast room don't know what Li Sa is thinking at the moment, but seeing that all of them are doing things in an orderly manner, they are inexplicably at ease.

[I thought that the anchor had softened his heart before forming an alliance with others, but I didn't expect to turn around and cripple those two teams without a single soldier.] ]

[Psychic abilities are terrifying, but not when an opponent has psychic defenses.] ]

[Didn't that bearded defense ability also protect against psychic snooping at the beginning?] ]

[Unfortunately, the man's ability is too low.] ]

[Is the anchor deliberately strangling potential opponents in the cradle?] ]

If Li Sa didn't have this kind of thought in her heart, of course, it was impossible, and she hated the way the slave team did it to the extreme. That's not as good as Wang Xuyang's original pyramid technique, at least he spent his time to deceive the bottom and make the people who just joined feel a little human.

As for who to work with, Li Sa also adheres to the principle of mutual need and control. Don't look at Fan Gang's team, there are only two people who can contribute, but one of their abilities is long-range attack, the other can fly, and the mobility is relatively strong.

Huang Zihui cautiously asked Lu Jingjing beside her: "Shall we get some edible plants in advance and store them?" ”

Lu Jingjing actually has this kind of plan, but just now Dr. Yao has suggested that everyone go back to the cave as soon as possible, and she is also worried about whether it will be like what Li Tianya said, if it is completely dark one day, and more strange insects and beasts appear outside, it will be dangerous for them to stay in the outside world.

To be safe, they could get back to the ship and monitor the situation outside. After the external environment stabilized for a while after switching to polar night mode, and all kinds of danger factors were discovered, they went out to gather and hunt with sufficient preparations.

Lu Jingjing said: "Listen to the arrangement." But you have your captain, and we don't interfere with what you Captain Fan thinks. ”

After another while, Fan Gang returned to the cave with the seriously injured Zhao Yi.

He first tied the person to the rope and connected it by Li Sa, and then asked, "Can Wan Youfa and I also withdraw into the cave?" ”

Li Sa replied: "Our team will return to the spacecraft first, and the surrounding area will enter the polar night period in half an hour." You can choose to stay at the entrance of the cave, or if the situation changes, quickly retreat to the ship. ”

Hearing this, Fan Gang was very happy, and immediately informed Wan Youfa, who was still squatting on the tree outside, in the group, and asked him to withdraw to the cave as soon as possible.

Huang Zihui took out nine poison sacs at this time and handed them to Fan Gang, and said sincerely: "Captain Fan, I will listen to your arrangement and let me do whatever I want." I can also stay at the entrance of the cave with you. ”

Li Sa could feel Huang Zihui's heart empty when she said this, which was nothing more than a statement that she wanted to really integrate into the team, and her original intention was to withdraw into the spaceship to a safer place. At this time, she said this, which was nothing more than to increase Fan Gang's trust and favorability.

So Fan Gang asked, "Xiao Huang, if you activate the ability to see, will we be in any danger within half an hour?" ”
