Although there were a little twists and turns in the process, the three of them finally returned safely, and seeing that it was almost dark, He Jun decided to solve the battery problem tomorrow.

The trio had no problem with this, but they were very dissatisfied with the troublemaker on the seventh floor, and were ready to teach him an unforgettable lesson.

He Jun also has no opinion on this.

Although he knew very well that the cause of the incident was the indiscriminate smashing of the car on his side, and in the final analysis, the root cause was not in that person, but that person relentlessly made trouble, attracted the attention of the prehistoric giant beast, and almost killed several of them, and he really couldn't swallow this breath without teaching him a lesson.

That man wants to protect his property from being violated, there is nothing wrong with it at all, He Jun is thinking about how to survive in this ghost place, there are also good reasons, who is right and who is wrong is a bad account at all.

The ass decides the head, He Jun must, and can only stand in the perspective of his own interests, and must choose to support the revenge of the gangster trio.

However, it was too late, and he didn't want to get involved in the revenge himself, just supporting the gangster trio and reminding them that they had gone too far.

He Jun returned to his home through the rooftop, and as soon as he knocked on it, the door immediately opened from the inside, and Qiqi stood in the entrance with a flat mouth, with a look of dissatisfaction and resentment: "Uncle He, I have seen it all!" ”

He Jun couldn't help but be stunned: "What did you see?" ”

"I see you down there!" Kiki pouted and pointed to the window.

She ran to the window to look down when she heard the sound of firecrackers, but what she didn't expect to see was He Jun and two other people running wildly, avoiding the chase of the giant beast.

"Oh, it's fine, it's not dangerous at all." He Jun said disapprehantly.

"Uncle He, don't go out in the future, okay?" Kiki hung her head sadly.

He Jun pursed his lips, sighed once with his nostrils, squatted in front of Qiqi and said, "Actually, my uncle doesn't want to go out, but there is no way, if I don't go out now, what if I eat all the things at home?" ”

Kiki immediately said, "I can eat less, really, I can just eat a little." ”

"Silly boy." He Jun touched the top of Qiqi's head warmly, "No matter how much you eat, there will be times when you eat it all, we still have to live in this ghost place for decades, and we can never go out?" Only by adapting to the environment as soon as possible can we survive, understand? ”

Kiki looked at He Jun's eyes seriously and shook her head vigorously.

He Jun smiled dumbly: "It's okay if you don't understand it now, you'll understand when you grow up." ”

Although he said this in his mouth, his heart was in a trance for no reason.

He remembered reading in books that the average life expectancy of primitive people was only in their teens because of the harsh living environment, and at the beginning of the 20th century, the average life expectancy of Chinese people was only in their thirties, and it was not until the end of the 20th century that there was a significant increase.

But He Jun can't remember exactly how much.

In other words, even if the survivors in the community can unite and gain a firm foothold here, the difficult living environment will shorten everyone's life expectancy by a large margin!

Human beings live in groups, and it is difficult for individual individuals to survive, and in order to maintain the size of the population, all survivors must have as many offspring as possible.

However, in the prehistoric era when modern medical methods were lacking, the infant mortality rate was bound to remain high, and the only way to make up for the lack of quality was to make up for the lack of quality by giving more births and raising more.

At present, although Kiki is still young, she will enter adolescence in a few years, and at that time, it is likely that because of the pressure of survival, she will have to marry and have children like her as soon as possible.

Thinking of this, He Jun's heart was suddenly filled with guilt and guilt, and he secretly made up his mind that he would have enough say among the survivors no matter what.

Dinner was still instant noodles, and after eating, it was almost dark, and He Jun, who had been busy all day, comforted the depressed Qiqi with a few words, and slept on the sofa until dawn.

When He Jun opened his eyes, it was already bright, he squinted his eyes and glanced at the sunlight slanting into the window, his eyes happened to fall on the DIY corona on the windowsill, and he saw that the time was close to seven o'clock.

He Jun, who was in a daze, suddenly remembered what happened yesterday, his drowsy brain suddenly woke up, and he hurriedly looked at his watch, and found that the time on his watch was only more than five o'clock, which was nearly an hour and a half!

He Jun looked up at the wall clock on the wall, and the hour hand actually pointed to a point.

"Damn, what's going on?" He Jun was stunned and stunned, and his whole person was completely messy.

His watch has been adjusted twice, the first time from five o'clock to twelve o'clock, the second time two hours faster, and the wall clock has not been adjusted, if the watch is adjusted faster, the time of the watch is exactly the same as the time of the wall clock.

This means that there is no problem with the timing of the watch and the wall clock, unless the watch and the wall clock are out of order.

Apparently this is not possible.

The time displayed by the DIY corona is only related to the angle of the sun, and even if he draws it poorly, there are many errors, and it will not be exaggerated to the extent that it is two hours a day.

He Jun suddenly realized that the only explanation for this situation was that the Earth's current rotation speed was several beats faster than in modern times, so the time of the day was not twenty-four hours, but about twenty-two hours!

He Jun couldn't believe this answer anyway, but Sherlock Holmes said: After eliminating all impossible situations, the remaining one, no matter how absurd, is the only truth.

Moreover, he could not think of a second explanation that would explain the situation and make sense of it.

Thinking of this, He Jun shook his head with a wry smile, looked at the watch on his wrist that had lost its due role, and finally didn't take it off.

Even if the time on the watch is a little worse, it is always better to be able to calculate the approximate time by brain supplement, which is much better than not even figuring out the approximate time.

Eleven hours during the day and eleven hours at night?

He Jun sighed, awkward is a little awkward, but he finally figured out the reason why the watch kept making mistakes.

If only you could set the speed at which your watch moves!

He Jun thought regretfully.

But it doesn't make much sense, the battery of a wall clock can be used for a few months at most, and the battery of a watch can be used for two years at most, and sooner or later what modern times bring will be obsolete by time, and in the future it will inevitably depend on the corona to keep time.

It is said that by observing the Big Dipper, you can roughly estimate the time of night, although there are no Big Dippers at all, but you should not go to bed so early at night, but take some time to carefully watch the stars in the sky, and maybe you can find a few more stars to replace the Big Dipper and act as a timekeeping tool in the night.

He Jun got up with a confused mind and began to prepare breakfast for two.
