At four o'clock in the afternoon of April 12, Chen Duyun left the Yunzhou City with his troops.

"The current construction technology is awesome, but why not apply it to agriculture?"

Chen Duyun heard a squad leader named Ah Tu talking to himself, and although he was anxious to go south to clear the obstacles for the troops, he patiently answered his question when he thought that no matter how anxious he was, he couldn't be in a hurry.

Atu's problem originated from the newly built outer city of Yunzhou. In order to guard against large-scale magic in the Age of Magic, no matter how developed it is, the ancient building of the city wall is preserved, because in people's inherent concept, this is to protect the city, and installing enchantment equipment on the city wall can get a systematic bonus.

Normally, the city walls were enlarged along with the city, but with the progress of the times, the rate of urbanization was faster than the level of technology to expand the barrier, so people chose to use the two methods in parallel, that is, to let the people outside the walls hide in the city only when there is a battle.

What I want to talk about here is the problem of wartime maps, as we all know, the map will expand after the war, and theoretically the system will expand the folding world in order to prevent people from fighting and destroying the planet, but this is not the case of the technological world in the novel suddenly turning into a magical world, the earth will not suddenly collapse, and the city will not be destroyed.

The Celestial World system has taken a more intelligent approach, expanding the map without interfering with artifacts, and this does not include roads.

For example, the farmland outside the inner city of Yunzhou is intact and the area has not changed, but the empty areas between and around the farmland have expanded a hundredfold. Just as there is only one road between the city and the mountain, and nothing else, the end result is that the road still exists, but it has become a hundred times longer, and the section of the road that should have been flat in the middle has become rugged, or it passes through a swamp and leads to the bottom of the lake...... All in all, the real intention of the map expansion is to expand the cost of transportation, increase the difficulty of people's communication, but do not affect the production capacity of human beings, how many resources should be excavated from the original land, how many crops can be produced, the map is still unchanged after the expansion, and the expanded land will not give you the possibility of finding additional underground resources, even if there is, it is an approximate but unusable "semi-virtual thing", something that will disappear after the end of the war.

But human beings are very smart, even if they play games, they love to drill system loopholes, not to mention reality, how can you be happy if you don't open your life, reality is often more absurd than fiction, it's not a word to say.

Not to mention the specific operations, the most famous is the Great Wall of the Qin Emperor, in order to ensure that the Great Wall can also play a role after the map is expanded, he adopted the method of assigning soldiers to stand guard and place artificial objects. One of the reasons he was called a tyrant was that he buried sinners and prisoners of war in the Great Wall, maintaining only a minimum of life and forming the Great Wall of Flesh and Blood. As a result, before the death of Emperor Qin, every time the foreign tribes in the north arrived, they had to face a million-mile Great Wall that was expanded by a hundred times with the map, and the system didn't know if the algorithm was wrong, so it not only increased the height of the Great Wall, but also helped expand the magic cannon on the Great Wall...... It's not a hundredfold, but you can see the top of a giant mountain of mutations, and a black lacquered cannon like a giant beast opening its bloody mouth is facing you.

Some people may ask, after the Great Wall is expanded, the distance between people buried in it will also increase, and it will become a "useless place" that is not recognized by the system? Also, why are they all mountains, and the system is stupid not to build a lake to let the Great Wall go to the ground? Is Emperor Qin the system's own son, and why is he treated so favorably?

In fact, Emperor Qin may really be the son of the system, not to mention that the lord of China has always called himself the "Son of Heaven".

Yes, the distance between the people buried in the Great Wall has indeed become larger, but the people inside are not recognized as people, only recognized as "man-made", and the result has also become larger with the errors of the system, so to speak, the Great Wall after that is composed of giants of no hundreds of meters, even if it is like this, there is a large gap, but there are mistakes that people do not admit, who expects the system to recognize those other mistakes. As for the terrain where the Great Wall is located, there is no place to do it, which is a common record of the system and human historians!

The Qin Emperor became the "Son of Heaven", which is well deserved.

But even such a once-invulnerable Great Wall later collapsed because of Meng Jiangnu's search for a husband, even if communication was not developed enough at that time, and the news was subsequently suppressed, the brutality of the Qin Emperor still spread far and wide, and then completely exploded after the death of the Qin Emperor.

The Qin court, which was plagued by civil strife, could not maintain the feat of soldiers standing guard and placing artificial objects, and with the removal of these, the Great Wall completely lost its former charm. Later, when the Han Dynasty was about to eliminate the overlord, the Great Wall could only be integrated with the mutated and expanded terrain like an ordinary road, and the funniest scene was that a certain terrain became a cliff from afar, and the Great Wall actually passed under the cliff, and the slightest defensive effect could not be played.

Later, in the Northern Tang Dynasty, without the advantages of the north, naturally would not go to great lengths to find loopholes in the system like Emperor Qin, but there is still a positive significance, that is, people know that the system will also make mistakes.

Speaking of the outer city of Yunzhou, of course, this is not that Pharmacist Li intends to imitate his predecessors to do things that make the system go wrong, but after the map is expanded, the fields, mines and factories outside the city are relatively far away, considering the need for self-sufficiency in long-term combat, he temporarily built a wider outer city wall outside, this kind of city wall can only be arranged with some local enchantments, and the electronic elves cannot manage it, but how can it also play the role of sentry and simple interception, it is still very necessary.

Ah Tu lamented that the project was completed in a short time, but the people farming and mining minerals on weekdays are still so low-end, suggesting why the country has not done everything so that the people can live a comfortable and happy life.

"Actually, our Great Song has basically solved the problem of food and clothing, and as long as there is magic, people will not starve to death, the only problem is accidents. ”

It's great that the wizarding world can come out of nothing, but natural disasters have also become stronger with the advent of magic, and people can only spend money to buy things when the original fields are destroyed and people's magic power is limited.

Indeed, a seventh-order magician like Chen Duyun managed thousands of acres of land by himself, and it was not difficult to grow food, not to mention that he could use the agricultural magic guide machinery developed by the Mo family, in fact, the Great Song Dynasty could have carried out fully automatic agriculture a long time ago, but why didn't he do it? Because this would rob the lower-class people of their jobs, of course, you would say that they could transform into maintenance machinery or become industry-oriented, but this requires education to keep up, and these people are willing.

In the face of war and the safety of life, it was very difficult for the Great Song Dynasty to migrate the population, and in order to make money, they drove people to change careers? Hehe, why should I accommodate for your convenience. You can't grab it! I've long seen that group of rich people are unhappy!

So nothing has changed.

Of course, this is not an eternal situation, but it must be done step by step, and only when the national cultural quality reaches a certain level can we completely give up handicrafts, the Great Song Dynasty has a clear idea in this regard, and five college students like Chen Duyun are also very sober.

"Well, it looks like I'm too stupid. Ah Tu patted his head and smiled.

"It's fine. ”

After answering, Chen Duyun couldn't help but sigh.

This approach is of course necessary, but its backwardness is also extremely obvious, let the people do their own thing, of course, it solves the employment problem, but just like the old old thinking, people are always making the same mistakes, today this small shop closed for a certain reason, and the next day a similar shop several streets away also closed down for the same reason. Of course, more often than not, it is because of insufficient funds and too fierce competition that leads to failure.

It is worth noting that this is all the mutual consumption between the people at the bottom, and their failures cannot shake the part of the people who have succeeded, even if they are lucky enough to kill from the bottom, most of them are co-opted by the giants, and eventually develop into an oligopoly.

"Alas, the power of the people is huge when combined, but if they can't be integrated and fight separately, they will be just a bunch of scattered sand. ”

Chen Duyun, who sighed like this, glanced at Ah Tu and the troops behind him, but there was a flash of inspiration.

Ah Tu is already a fifth-order after taking the body-strengthening pills, in the past, this was the regiment commander level, even now, most troops will use such a person as a squadron leader, because unlike the regiment commander, the squadron leader does not need much knowledge, as long as he has combat power...... But in the elite troops of the Yue family, he is just a squad leader, which shows the high quality of the troops.

But no matter how high it is, in the face of a blow from an eighth-order powerhouse, it is just a quick defeat. Of course, there is a combination of magic, but the strong man of the enemy is not alone, and even if it is, the civil war stage has long proved that once the team is broken up and the combination is no longer combined, it can only be a simple competition between the individual strengths of the armies. What is the difference between such an army and those lower classes of people who are fighting like scattered sand?

Chen Duyun couldn't help but think of Liu Tian's teachings:

"Is it really impossible to defeat 3,000 against 10,000? No, 3,000 people have an absolute advantage when dealing with 1,000 of these 10,000 people, as long as they only fight 1,000 people at a time, let alone 10,000, even if it is 100,000, 3,000 people are enough to win!"

"How can it be done? How can someone else be so stupid to let you break it one by one. ”

"It depends on your tactics and ability, and you must know that even if you have 3,000 men, you may be able to exert less than 3,000 combat power. ”

"What do you mean?"

"Big brother, you know that the troops are not spread out with 3,000 people one-on-one, right? In this way, when the people in front are fighting, it will be difficult for the people behind to fully exert their strength, and when charging, it is possible to hinder the people behind because they fall or are captured by the enemy as a meat shield, and considering the terrain and the density of the formation, if you have a bunch of magic bombs with 3,000 people, you may be able to blow up the people in a hundred blows, and there are also those who use defensive magic?"

"You mean, try to make the attack hit the enemy 100 percent?"

"I didn't say that, I couldn't do it anyway. ”

At that time, Liu Tian smiled meaningfully. In retrospect now-

"I ...... Is it possible?" Chen Duyun muttered to himself.

The white robe behind him fluttered in the wind, as if he wanted to sweep the wind and clouds of this land.
