'Welcome back, hard work along the way. Pen, Fun, Pavilion www.biquge.info', Li Chen was at the pier, welcoming Yixin and Huang Tiansheng and his party back. 'Uncle. Yixin is still like that, simple, but no one who knows the inside story will say that he is stupid.

'Really, I'm tired. Huang Tiansheng stretched his muscles, "I'm old, and I'm still running around with the little doll." ''A handful of age. Li Chen seemed to smile, "I remember that you are only a few years older than me, so you are too old." ’

'Why, or you will bring it. Huang Tiansheng blew his beard and stared at his eyes, his short beard was messy, "In the past few months, we have run from Yangzhou to Guangfu, can we not get tired after such a trip?" ''It's tiring, but it's rewarding, isn't it?'' ’

'That's it. Huang Tiansheng twisted his short beard, "It turns out that our earth is really a circle, which can be understood, the sun and the moon are all round." But it's weird, if that's the case, why don't we fall?. Huang Tiansheng began to think about it, not thinking about where he was now, or Li Chen commanding everyone to move everything back.

Huang Tiansheng and Yixin, they made a long journey, from Yangzhou to Guangfu. This is not Huang Tiansheng's request, but single-mindedness, this kid is stubborn, and he has to make such a trip.

I hope that when I come back this time, I will not be stupid anymore. Ah Xiang said worriedly, in fact, Yixin's stubbornness was committed on the way from Xufu to Yangzhou. At that time, Ah Xiang didn't care, and later told Li Chen that Li Chen observed for a few days, and found out that he was not stimulated by being forced to flee, so he stopped paying attention, maybe he found something funny, watching the stars every night.

Li Chen was also young, and knew that sometimes, people would suddenly be interested in a certain thing, and then it would be gone, anyway, stargazing is not a bad thing, the only thing is that it is cold, and you should pay attention to stargazing and don't catch a cold.

After that, Huang Tiansheng came, he studied astronomy and meteorology very much, and he happened to get together with Yixin, and he had this trip.

Li Chen agreed, mainly because he found that his whole life had calmed down all of a sudden, and there were no troublemakers, as if they had all died down, and Li Chen did not relax his guard because of this. It's just that there has been no movement for a long time, only a thousand days to be a thief, how can there be a reason to prevent thieves for a thousand days, and later Li Chen continued to recruit many old feet, all of whom are relatively young, equipped, and have some combat experience, and bring their families to vote.

With these people, in addition to strengthening precautions, Li Chen divided a part of the people to protect Yixin and Huang Tiansheng and his party to leave Yangzhou and do their own things.

'Sophomore, sophomore, I'd better not have anything to do. Back at Li Chen's house, Huang Tiansheng ran in with a shout, where does he live? Of course not, it's just that Huang Tiansheng asked Gundam to help him make something before he set off, and now he doesn't know if it's done, and he can't wait to see it. So he completely ignored the exhaustion of the journey, and was busy looking for Gundam, a sophomore in high school.

'What's the noise. Gundam was in his, well..., the professor's lounge, calculating something, and when he heard the shouting, he shouted angrily, "It's you, I haven't seen you for so long, and the light will shout over there." ’

'Where's the thing?' Something is not done. Huang Tiansheng asked nervously, "It's done, I'm annoying, don't come and quarrel with me." After that, he closed the door and continued his research, "That's right." Suddenly, the door opened again, and Gundam rushed out, "Since you're back, I'm sure I'm coming back too, I'll ask him to help me calculate something." ’

'Neuropathy. Huang Tiansheng didn't care if he was the weirdest one, so he was going to find something that Gundam promised to do for him, but..., he stopped, "Where is that thing?" Huang Tiansheng was dumbfounded, Gundam said that things are the best, but where to put them?

By the way, look at his study, if there is anything in the study. Huang Tiansheng clapped his hands, thought of it, see that the door of the Gundam room is not closed, this is not me trespassing by myself, you don't close the door yourself, Huang Tiansheng comforted himself. In Li Chen's place, respecting other people's study is a rule not to be, because you don't know if he is busy, and all researchers don't like to be interrupted by others. If you don't respect other people today, no one will respect you another day.

'What is this?' Huang Tiansheng entered the Gundam room, anyway, if you are not there, I will definitely not be able to disturb you, but as soon as he entered the room, he saw a strange-looking rectangular wooden box, standing on the ground. It is said to be a wooden box, but it is actually the appearance, and the front is two pieces of glass.

Rectangular, transparent glass, through below, two strange things can be seen. On it is a small square wooden box, with slightly smaller glass of the same type, and then there is a plate inside, and three needles can be seen in the plate, the thinnest one, the fastest one, the slightly thickest one, the longest one, you can see the thin one running a circle, and it will move.

The thickest and shortest one, completely motionless. Then on the board, there are 12 heavenly stems, directly above is the son, directly opposite, and at the bottom is noon.

'What is this?' I can move by myself, but I don't see the power. Huang Tiansheng circled this thing strangely, the needle could move, indicating that there was power, but he didn't see anything in this wooden box that made the needle turn.

'Isn't it? Huang Tiansheng realized, he turned back to the front, and found that there were major rectangles below. It's also clear glass, and there's a pendulum in it, swinging around regularly, and he knows this, it's the pendulum theorem, 'Is this the one that provides the power?' It's weird. ’

I'm not here to see this. He suddenly came to his senses, and was about to look for Gundam's room, if there was any indication of the location of the thing, Gundam dragged in with a rush of thought.

'That's it, you can help me do the math. Gundam pointed to the wooden box, completely ignoring Huang Tiansheng next to him, and said to Yixin, "I originally divided this thing into 12 equal parts and treated it as a day." But your uncle, 12 equal half a day. It's 24 equal portions a day, but then the calculation has to be done from scratch. Do the math for me. ’

Speaking of calculations, Yixin was very interested, so he began to calculate, and at this time, Gundam found out that Huang Tiansheng, "I said, what are you doing here." He wasn't unhappy that Huang Tiansheng ran in, but he didn't like that when he started to do things, there were idle people and so on, no matter what he did.

I'm asking you where you put it when you promised to make it for me. Huang Tiansheng didn't look for it, and asked me directly if it was faster, "That thing, it's outside, let someone take you to find it." Anyway, it's not hard to find such a big one, and during the period when you didn't come back, a few children took over your work and were stargazing. After saying that, he blasted him out.

'You've got a surprise. Before driving people out, Gundam said this, Huang Tiansheng was itching, and he couldn't wait to find someone to lead the way. He was curious to know what the surprise was. (To be continued.) )
