"Hey, what a big playground! Is it used for military training?" Under Xiang Yu's guidance, Liu Wuyi and the others came to a place similar to an arena.

Looking up, there are two football fields the size of here, the ground is as solid as granite, in addition to leaving an open field where you can practice martial arts, there are some obstacles and other equipment used in the army for training on the field, and there are several rows of weapon racks in a corner next to it, and there are some equipment similar to barbells, dumbbells, sandbags, iron locks and other equipment for exercising strength.

"Well, this is my brother's own martial arts training ground. Xiang Yu scratched his head a little embarrassed, although he was an emperor, he occupied such a large area alone for martial arts, and even Xiang Yu himself felt a little unreasonable.

But this is also a way to do things, Cangran to establish a country with martial arts, martial arts is an extremely important guarantee, since the founding emperor, this martial arts training ground has existed, and there is an unwritten rule, when the emperor is practicing, there is no 100,000 urgent, any idle people must not approach within a kilometer here, otherwise there will be no forgiveness.

"Ann, al, it's not a big deal. Liu Wuyi patted Xiang Yu's shoulder with an expression that I understood, got off the horse, walked to the instrument next to him, reached out and picked up the iron lock on the ground, but his shoulder couldn't help sinking: "Good guy, this thing looks small, and it's really not easy to start." ”

After waving the iron lock a few times at random, Liu Wuyi suddenly noticed a strange phenomenon, on one side of the iron lock was clearly engraved with such a row of words-1000KG.

"Occasionally, it won't be dazzling, right?" Liu Wuyi subconsciously rubbed his eyes, and looked at it carefully, yes, it was 1000KG, what was going on? At that time, Liu Wuyi's mind was a little confused.

"Oh, this is the unit of measurement on our planet, a thousand kilograms, also called a ton, which indicates the weight of this iron lock, in our place, generally speaking, only when weighing super-large mass objects, we use tons as a unit of measurement, usually we use kilograms as a unit of measurement, and light weight can also be expressed in grams. Xiang Yu saw Liu Wuyi looking at the numbers, and took the initiative to explain in detail to Liu Wuyi, and between the words, Liu Wuyi also heard the word planet.

"Excuse me, do you use the decimal point? What is the unit of length you use to calculate length, and don't you use the unit of currency here to calculate it in two?" asked the somewhat chaotic Liu Wuyi without thinking.

For Liu Wuyi's curiosity, Xiang Yu patiently explained, and the result was exactly the same as the conversion method on the earth, and according to Xiang Yu's explanation, the human beings on this planet really have some blonde hair and blue eyes, or different shades of skin, and the language is very different from the human beings here, but the number of humans in these races is relatively small, most of them live in the western part of the human region, and the way of life is not the same, of course, after thousands of years of development, the cultures of the two sides have learned from each other's strengths, and most of them have been integrated together, which not only makes Liu Wuyi have infinite reverie。

A group of yellows or Westerners dressed in classical costumes have Arabic numerals, decimal points, and English letters representing various units of measurement affixed to traditional Chinese characters written with brushes and quill pens. Well, how do you say it? Is this an evolution of culture? Or is it a fusion of knowledge?

"By the way, do you still know about the planet?" Liu Wuyi, who came back to his senses, somewhat understood what was going on, but still wanted to confirm it.

"That's right!" Xiang Yu nodded and replied: "We got the understanding of the planet from the books left by the ancients, it is said that the ancestors of all our royal family members were part of the ancestors, and settled down after living here because they could not leave, and after tens of thousands of years of development, such a situation was formed. In fact, if you really want to talk about it, those civilians outside are the real masters of this planet. ”

"Your Majesty, please respect yourself. Xiang Yu's words made Xiang Liang on the side a little panicked, and hurriedly spoke out to stop him.

"Uncle Huang doesn't have to be nervous. Waving his hand at Xiang Liang, Xiang Yu said calmly: "Being able to take the facts seriously is actually a kind of progress in thinking, I am right." ”

"This ······ What His Majesty said is that the old minister is ignorant. "The emperor doesn't say anything else, Xiang Liang, who is a courtier, naturally can't do it against the emperor because of this kind of thing, not to mention that Xiang Yu even said the word I, indicating that he was in a somewhat unhappy mood, and hurriedly bowed down and clenched his fists and said.

"Here's the thing. Seeing that Liu Wuyi and the others were a little unclear because of the conversation between the two, Xiang Yu explained: "This matter involves the stability of the people's hearts, which is generally only understood by real members of the royal family, and it is usually forbidden to communicate, and if it is not done well, it will implicate the lives of many people." ”

“Isee，Isee。 Patting Xiang Yu on the shoulder, Liu Wuyi had an expression that he knew very well.

"Oh, yes. Suddenly remembering something, Liu Wuyi touched his head and asked, "How do you keep time here, I have asked other people occasionally, but the explanations are different, and they still look very backward." ”

"Brother Liu is the right person. Xiang Yu nodded and said: "This also involves confidential issues, and the timer is also a technology controlled by various countries, which is only mastered by members of the royal family, and is only used for marching and fighting wars." ”

As he spoke, Xiang Yu took out a disc with two palms in his arms, and without thinking much about it, he opened the lid and handed it to Liu Wuyi's hand: "This is the timepiece we use, we call this thing a 'watch', and there are three needles in it, which represent different timing methods." ”

"Occasionally, the pure gold dial is, damn, there are so many diamonds, even the cover is a high-quality crystal, pure handmade! How much is this worth!" Liu Wuyi, who took the watch, directly ignored Xiang Yu's words, and was not too heavy, touching the watch with stars in his eyes, and muttering in his mouth.

"Uh, Brother Liu, this thing is priceless to us, and the entire Cangran Kingdom is only a handful of them, and for the sake of secrecy, the production process is also sealed, and it can be said that no one in the countries knows how this watch is made except for the emperor of the dynasty. Looking at Liu Wuyi's look of love, Xiang Yu was extremely embarrassed and at a loss.

"Anla, Anla, as the saying goes, a gentleman doesn't like people, this watch looks like it's handed down from your ancestors, I'm afraid even if you know this craft, you won't bother to do such a piece again. Just by looking at it, Liu Wuyi knew the timekeeping method of the watch in his hand, and returned the watch to Xiang Yu casually, and said mysteriously: "Brother, don't blame Brother Duokou, even if you don't want to be an emperor in the future, you only rely on the craft of watchmaking, which is enough for you to be rich and expensive." ”

"Hahahaha, Brother Liu is really joking. Gently wiping the sweat on his forehead, Xiang Yu smiled with a crying face, but thought in his heart: You and I haven't thought about it, but once I say it, I am afraid that I will be scolded by those old guys, and it will be a big rebellion.

According to the table just now, Liu Wuyi marked two times on the information recorder with reference to the time of the earth, no way, the things that you are used to will not be able to change for a while and a half, if you really live according to the time of this planet, even Liu Wuyi will probably go crazy, living here for four days a day on the earth, whether it is a day when the sun shines for nearly forty hours, or a long night, it is unbearable to think about.

What's more, Liu Wuyi and the others don't want to live on this planet for the rest of their lives, and they still have to leave after all, as for how to go, they can only explore carefully.

In the dark, Liu Wuyi always had a feeling that the unknown item that attracted him and others to this planet must be the key to solving this incident.

It's just that before entering this Chu Heavenly Emperor City, he obviously felt that there was a strange fluctuation here that attracted him, but after arriving here, this fluctuation disappeared again, could it be related to the hidden enchantment here? It seems that this Chu Heavenly Emperor City is too worth exploring, Liu Wuyi, who had made up his mind, thought secretly.

A group of people chatted for a while on martial arts practice, and Liu Wuyi got some useful information from Xiang Yu's hand, although Xiang Liang tried to stop it several times, but Xiang Yu blocked it.

Of course, Liu Wuyi is still very generous, and on some related scientific and technological issues, under Xiang Yu's humble advice, whether it is useful or useless, they all printed out a copy as a reward for Xiang Yu's hospitality.

Liu Wuyi's move can be said to be a generous gift to Xiang Yu and even Cangran Kingdom, although some of the things in it are not used now, but it will give people an inspiration, and it will play a key role in the future development of Cangran Kingdom, it can be said to be a treasure-level important information, if other countries know about it, even if they don't immediately launch a war of annihilation, I'm afraid it will cost a shocking price to exchange.

So much so that in the end, the emperor's uncle Xiang Liang not only did not dare to speak out against it, but even knelt down on the spot in the face of Xiang Yu and Liu Wuyi and others, snorted his middle finger, and swore in the name of the ancestors of the Xiang family, if he dared to leak a stroke of today's affairs, he knew how to die without a whole body, and after he died, he didn't know how to die ten times or a hundred times, anyway, how miserable and how to die, how to die if he was better than to die.

"Xiao'er, I didn't want to answer the question of the old man just now, but now I can make you a baby by giving you a bunch of garbage, even if you are an imperial uncle or a yellow book, you still have to kneel in front of Lao Tzu in the end. The puppet old man is so careful, he doesn't want to negotiate with you, and he doesn't negotiate with you. Looking at Xiang Liang, who was kneeling taller than himself, Liu Wuyi had a look of underweight, and gently stroked the information recorder on his arm, wondering if he could copy so many more copies of this video and sell it to Xiang Liang's opponent, it is estimated that it will be a considerable income.

This planet is big and the dawn is slow, a group of people can be said to have finally seen the rising sun after two or three hours after eating an early meal, although they have been on this planet for a while, Liu Wuyi and others are still not used to it.

"Brother Xiang, it's all dawn this day, do you want to go around somewhere else?, or do you have to come here every day for a sunbath in the morning sun before doing something else?"
