The first sentence of Lin Sisi's essay is, will there be aliens in the universe we live in? This is a topic that our planetary observation team has been working on.

- Although science and technology are constantly evolving, and new news comes every day, compared to the vast universe, the members of the planetary observation team know that our human civilization is still in its infancy, and if there are really other intelligent life outside the solar system, how do they view us, and do they have good intentions or malicious intentions towards us?

Zhang Heng raised his eyebrows, for a child of Lin Sisi's age, this weekly diary is simply mature, Zhang Heng remembered the girl in the photo, she looked thin, with sparse bangs on her forehead, standing in the crowd is not very conspicuous, and it is easy to be ignored.

Therefore, few people know what kind of sea of stars is hidden behind the somewhat shy eyes of this ordinary little girl.

Zhang Heng spent five minutes reading the entire weekly diary, and found that the content on it was completely different from what he had thought before.

He had been in contact with Lin Sisi's homeroom teacher, Li Yan, and it was from the latter that he knew about the existence of this composition.

But I don't know if it's because the other party was a little too nervous at the time, and there was some ambiguity in the expression.

In fact, Lin Sisi's composition mentions a total of two waves of aliens.

Or according to the different attitudes towards humans, she divides aliens into two categories, simply put, one is willing to help humans, and the other is the life that is malicious and aggressive towards humans.

According to Lin Sisi, the latter came to Earth as early as the Cretaceous era, with a strong ability to camouflage and learn, and was almost at the top of the food chain, but then an accident happened, and these things survived the Tertiary extinction event, when most of the animals and plants on the earth, including the dinosaurs, were hung up in that catastrophe, and those things could not escape.

But they didn't die there, and the mother, which was the core of reproduction, escaped through a long period of self-dormancy. However, because it is not known when the disaster will end, and whether the environment will be suitable for survival after the end, it has been dormant for an unusually long time this time, and only recently has it awakened.

And when it woke up, it found a better camouflage than the dinosaurs.

- Humans at the absolute top of the food chain.

"This will be the greatest catastrophe in human history, but unfortunately humans on the prey side do not even realize that this battle has begun." Lin Sisi wrote at the end, "The adults are busy with their own things, and they are still thinking about the trivial things in life, but fortunately, the members of the planetary observation team have found a way to stop this disaster, and we will fight for the fate of mankind." ”

…………

Zhang Heng put down his mobile phone, Lin Sisi's weekly diary may be just a child's cranky thoughts in the eyes of ordinary people, especially how to look at the bloody lines of fighting for the fate of mankind at the end, but most of the people who make this kind of middle two remarks are little boys who have nowhere to vent their energy, and it is hard to believe that a quiet girl like Lin Sisi will have such a passionate side.

It's a pity that she and her planetary observation team have not been able to stop this catastrophe that is vital to the survival of mankind.

A few years later, when we look back on this summer, we will only remember that there were three little ghosts who did not listen to their parents and came to the river at night to play, and finally drowned, and they may also use this incident to educate their children, what will be the consequences if they do not listen to their parents.

Zhang Heng didn't know if the three of them would make such a choice if they were given another chance.

Unfortunately, there is no option to start over.

Most of the pages in this weekly diary are about the evil "aliens" who came to the area in the Cretaceous era, and many of the contents can also correspond to what Zhang Heng saw under the No. 3 warehouse, which made Zhang Heng know more about those things, but about the specific methods to stop the disaster, Lin Sisi did not write it in the weekly diary.

However, Zhang Heng still found some clues between the lines.

He has also been investigating those things during this time, but he must admit that the other party is indeed cautious enough, until he ventures into warehouse 3, even with his skills, there is not much gain, and the three members of the planetary observation team are only fourteen years old, it is unlikely that they can find so much information on their own, especially since even the old background of those things has been turned out, all the way back to the Cretaceous, and the events that happened tens of millions of years ago are completely restored, which is something that even top archaeologists can't do.

So they must have gotten some kind of help.

Combined with Lin Sisi's classification of aliens before, Zhang Heng realized that there are likely to be two types of life forms that can be called aliens in this copy, in addition to those things that are enemies of human beings, there is also a class of alien races that stand on the position of human beings, they may not just be just to help human beings, but they may also have some grievances with the previous type of things.

After all, this was just a copy, Zhang Heng didn't care what the latter's true purpose was, as long as they had a way to destroy the strange creature under the No. 3 warehouse, then Zhang Heng could cooperate with the other party.

So the current situation is back to the original problem.

How is the clue on the planetary observation team's side going forward?

Zhang Heng is destined to lack sleep these days, he is used to having 48 hours of activity time in the real world, and when he returns to the 24-hour system in the copy, Zhang Heng actually begins to feel that the daily time is a little insufficient, especially when he has to deal with things in school, keep swiping cards, and let those things relax their vigilance.

With no teammates to rely on, Zhang Heng could only entrust Bai Qing to investigate the matter of the planetary observation team.

He didn't sleep for a few hours at all, he went to the hotel where Bai Qing was early in the morning, and after the two exchanged codes, Bai Qing opened the door and let Zhang Heng into the house.

“…… You say there's another group of aliens out there? Bai Qing was surprised after listening to Zhang Heng's words, this is too lively, what is this, is it an alien sorority?

"The other group may not be on Earth." Zhang Hengdao, he has analyzed the current situation, those shadows in the fourth ventricle did not stop after the drowning of the fake planetary observation team, but continued to look for something.

"Our goal should be one thing." Zhang Heng said, "I don't know what that thing looks like, but it's obviously related to those three children, we have to think about where to start." ”

"Planetarium." Bai Qing suddenly said at this time.

"Huh? You've told you that the kids often leave the neighborhood together, and then their team is called the Planetary Observation Team, and I think they're going to a planetarium. ”

Zhang Heng frowned, "I have also considered this possibility, but the planetarium and their residence are too far away, almost a dozen kilometers, considering their age, it is impossible to run that far." ”

"No, no, no, I'm talking about the old planetarium, my grandmother's house is also there, I lived there for a while when I was a child, so I know there is still an old planetarium there, but after the new planetarium opened, it has been changed to a children's palace, and it has been many years." "The old planetarium is very close to their neighborhood, and it only takes ten minutes to walk. "I have 48 hours a day with the latest chapters coming to the URL:
