Chapter 4132: very suitable

For Shi Zhan, after having the concept of latitude and longitude, it is enough to determine the latitude and longitude point, and then formulate the formula to calculate the distance of another latitude and longitude point. The whole process is simplified to a certain outrageous degree.

"Well, that's it, my method is not bad." Wan Zhen asked excitedly.

"It's more than good." Shi Zhan said with a bit of emotion, "We, the Gan Shi family, have never thought about this for thousands of years. Obviously Chang'an has already made such a layout, but I have never thought about it. Let it go."

This may sound outrageous, but in fact it is true, because from the time when Chang'an City was first established in the Han Dynasty, until the 21st century, the internal roads were basically straight from the south to the north, and from the east to the west. of that distribution.

Therefore, the location of Chang'an City can be positioned by means of Dongxi Street and Nanbei Street. Of course, the unlucky child who should get lost will still get lost in this case. .

It is precisely because of this knowledge that Shi Zhan can quickly respond to what Wan Zhen said, but compared to the actual layout of Chang'an, the latitude and longitude on this spherical surface are more dependent on their imaginations. , but with Changan as a reference, there is no problem with this method.

"I don't understand what you guys are talking about." Li Jue said in a very calm tone, but Wan Zhen smiled when he heard the words. This kind of thing, even if he thinks these things are very simple.

"I also thought of this incidentally. The earth is a ball. It was calculated by the two of you, and the concept of the pole of the earth was proposed by the King of Kuaiji, so from the pole of the ball, the maximum circumference of the throne of Weiyang Palace is passed. For the warp." Wan Zhen said to Shi Zhan with a smile, and at this time Shi Zhan couldn't help but admire Wan Zhen.

These things are not miraculous to put it bluntly. The concept of the earth's poles was proposed by Wang of Kuaiji. Although there is a lot of confusion, up to now, everyone who studies astronomy and mathematics basically agree with this concept. Although theoretically, the ball has no poles. Yes, but Kuaiji Wang has proved the existence of magnetic poles, so the giants are also willing to give face and admit that there are poles.

After all, having such a pole is really useful at some point.

Just like now, the curve where the north and south poles run through the throne of Weiyang Palace on the spherical surface is taken as 0, and the reverse side is taken as 180. The next steps Shi Zhan can count on his mind without thinking at all, because there are nearly twenty-four hours in a day, then the meridian is 15 The time zone can be directly made according to the rotation of the earth.

This is not the most important, the most important thing is that they have calculated the maximum circumference of the earth, so they can directly distinguish the distance from each time zone to the next time zone.

"Next, as long as the latitude line is made, the distance between the two time zones can be calculated according to the angle. In this way, if there is one clock as the time in Chang'an, the other uses the sundial, and the time can be determined by comparing the time. Our position on the vertical line of the earth." Shi Zhan had already caught up with Wan Zhen's thinking at this time, and was extremely emotional.

"The date and the angle of the sun at noon can roughly calculate the position of the horizontal line, so that the latitude and longitude can be roughly determined. It can be said that as long as there is a time comparison, it is almost the same." Wan Zhen gave the part that Shi Zhan had not yet responded to. After adding it up, Shi Zhan fell into silence.

This knowledge is difficult for ordinary people in this era, but it is not too difficult for the elites of the Ganshi family like Shi Zhan.

To be precise, these knowledge families all have detailed professors, but after thousands of years of time, none of the two families has summed up the knowledge.

On the contrary, when Wan Zhen first came into contact with these things, he put them together into a whole.

From a certain point of view, Wan Zhen may not be able to do research, but Wan Zhen is definitely a master of data piecing. Just like now, Wan Zhen has easily completed what others need thousands of years to do, and he still thinks it is very easy.

Although the knowledge reserves of these things have been completed as early as the second century, it took thousands of years to synthesize this knowledge to obtain operational and reusable technologies.

But this kind of thing is very easy to put it bluntly, just like now Shi Zhan just thinks that Wan Zhen is indeed talented, and does not think that this product has surpassed the years of thousands of years.

Because Wan Zhen and Lu Jun are very different. Although both of them have surpassed thousands of years, Lu Jun's transcendence is based on the knowledge developed and researched by himself, which is accumulated little by little, so it seems very shocking.

Wan Zhen's over a thousand years is different, because all the skills and knowledge of this guy have been summed up by his predecessors, but no one has integrated and interspersed these pieces of knowledge in a systematic way before, but this does not mean means that this knowledge does not exist.

In fact, the Gan family and the Shi family were reminded by Chen Xi that they calculated the perimeter of the earth, the ecliptic plane and the more accurate gravitational acceleration values. Every piece of data used by Wanzhen is their family. Yes, so they will only sigh with emotion in the face of Wan Zhen's results, but will not feel how shocked.

After all, for the Gan family and the Shi family who already had the foundation, they didn't figure it out because they didn't pay attention to this aspect, not because they didn't understand it.

But in fact, sometimes it is very scary to piece together a professional genius, and it is obvious that Wan Zhen is a typical technical piece of genius in history. Even among the more than 200 million people in the four major empires in the third century, Wan Zhen recognized it as the second. No one dares to be number one.

After all, it is impossible for a normal person to collect information and write a very accurate immortal work such as Nanzhou Foreign Objects by himself, and extract the knowledge he needs from the knowledge of others, and piece it together to create a new look. A very high-end wisdom.

Of course, at present, Wan Zhen doesn't feel that he is an immortal. At most, Shi Zhan is only impressed by Wan Zhen's knowledge integration ability, and he has not seen the shock of immortals.

"In the end, I still didn't understand at all." Fan Chou said with a look of sigh.

"If Wannianhou wants to understand this kind of thing, he still needs to learn some mathematics, and it is best to have a relatively advanced understanding of radians." Shi Zhan said sincerely.

The three of Li Jue sneered when they heard the words, study, learn a fart, is mathematics something their brothers should learn?

"Although it sounds very interesting, it can be used to distinguish our position on this planet, determine our distance from Chang'an Weiyang Palace, etc., but I don't think I can learn it at all." Wu Xi said with a sigh .

Speaking of which, Wu Xi's study is still quite hard, and he constantly strengthens himself, but it is obvious that the high-end knowledge that Wan Zhen talked about before is more terrible, and he can't learn it, and he can't learn it.

"Actually, there is no need for you to learn this. With me following you, it doesn't matter whether you will or not, I will do it." Wan Zhen said casually. He is now a member of the Xiliang Iron Cavalry. But he's also tough.

"Look, there is always a way to solve the problem, just like here, we don't have to learn it at all, we also have the correct positioning method." Li Jue said very calmly, and then looked secretly from left to right as if he remembered something. After taking a look, he made sure that Zhou Yu was not there, so he coughed twice.

"Ziran will say what she wants to say directly, and the brothers will not look down on you." Guo Si instantly understood Li Jue's intention, and said very casually.

"I'm thinking about a new problem." Li Jue asked people to block the transmission of the voice, for fear of being discovered by Zhou Yu, and then said cautiously.

"What's the problem, it's worth being so cautious, and what else is there for you to consider? If you can't do it, just jump to the gods. The gods can basically solve all problems." Fan Chou spoke in a sarcastic or perfunctory tone. said.

Li Jue didn't feel anything special when he heard the words. He and these two guys have been together for so many years, and he has long been accustomed to this way of communication, and he doesn't care at all.

"Do you think the ship we are on is a mount?" Li Jue suddenly made an astonishing remark.

I have to say here that the breadth of thinking of people who often dance the gods is difficult to surpass by others. Just like now, when this remark comes out, even Guo Si and Fan Chou are shocked. As for Wu Xi, Wan Zhen , Wang Fang, these scumbags, are even more shocked and don't know how to answer.

How can something like a boat be regarded as a mount? It's barely a normal Xiliang iron knight who thought of it and asked the same question.

"A boat is not a mount in any case." After thinking for a while, Wu Xi finally came to his own conclusion. Although the riding range of Xiliang Iron Cavalry is very wide, the boat is also a mount, which is really outrageous. .

"No, no, why can't a boat be regarded as a mount? This thing completely conforms to the attributes of all mounts, but anything that can be ridden is a mount, and a boat can also be ridden." Li Jue's question stimulated Wan Zhen's spirit, and his aura began to explode wildly. He had already thought of a lot of possibilities and operations.

"Theoretically speaking, we can use the First Auxiliary Corps riding the Rhino as a mount, so it is also possible to use other things as mounts." Guo Si thinks that this is a bit possible from the point of view of rationality.

"The question is, even if the boat is a mount, how much talent do we need to cover such a large mount?" Fan Chou asked, and Li Jue scratched his head as soon as he said this.

"Actually, when the first support was used as a mount before, you should have discovered that it is impossible for our talent to cover the first support and the rhinoceros." Fan Chou explained very seriously, "We are strong, but We also have limits."

The Xiliang iron cavalry is considered to be the top cavalry, and the most important point is that they do share their own talents with the mounts.

The talent of cavalry shared by horses is the foundation of cavalry's strength. In turn, to maintain this strength, it forces cavalry of the same talent level to have a real talent intensity much higher than that of ordinary infantry. After all, cavalry's talent needs to be shared with their own mounts.

This is also why the unlucky child of Tachito has lost three talents three times. On the one hand, the horse he changed was really good. When Xiliang Tieqi changed his horse, he could only give him to Sharma at first. It provides part of the ideal defense, and on the other hand, Tachito is actually very ambitious. This guy's warhorse fully enjoys all the elite talents of his own legion.

From a certain point of view, Tachito gave up his Frisian horse as soon as possible, and now it may be time to return to the third talent.

However, riding a horse is obviously superior, and heavy infantry is too flooded in Rome, so if Tachito is killed, Tachito will not give up his Frisian horse.

Don't eat more of Pompianus' food and wages. I'm sorry for the Spanish Almaden cinnabar mine that was drowned by Pompianus, so I mix it up and grind it slowly. Anyway, I have been promoted to three talents three times, and the foundation has been polished. It's in place, slowly grind it, and it will be almost the same after a few years of effort.

From this aspect, it is enough to see that the top mounts are also very troublesome for the talent consumption of cavalry. Of course, if you can be like Rahul, who has a bad luck, you can also give the mounts real talents. I did not say.

Therefore, it was replaced by the seventh-generation ship used by Zhou Yu. To be honest, let alone this thing itself does not meet the standard of a mount. Even if it really belongs to a mount, the Xiliang Iron Cavalry has no way to cover its own ideal defense. This size is really too much. It is outrageous, and it is not covered by individual talents at all.

"I didn't say that one person uses talent coverage." Li Jue smiled, "We can also control this huge mount as a whole. We have never encountered such a large mount before, and it is impossible for many people to ride on a horse. , but this time we can have a legion on this big ship, so that collective use of talent is not enough."

This is a very outrageous situation for a normal legion. If there is any conventional legion that can do it, I am afraid that only the extreme Danyang, which develops cooperation to the limit, can barely be regarded as a whole legion.

Xiliang Iron Cavalry would have been stuck at this step, but the outrageous illusion of congealing gave them the ability to fit together.

The three-headed, six-armed centaur is just a routine operation, and the sunflower evil **** with a thousand hands and a thousand eyes is the shape after a large number of Xiliang iron cavalry are combined.

Although it seems a little strange, if you think about it carefully, the Sunflower Cthulhu with Thousand Hands and Thousand Eyes is barely a whole, and it is reasonable to use elite talents to cover mounts, even if there is no such a big mount normally.

But isn't that the case now? Assuming that the seventh ship is a mount, the sunflower evil **** with thousands of hands and thousands of eyes is very suitable.
