Liu Sanyi naturally knows this truth, but whether these things can be preserved, this has a lot to do with the degree of resistance of the other party, if the other party's resistance is not fierce, then it will be relatively easy for Heitiecheng to defeat the other party at that time, then these ancient books can be preserved more, but if the other party resists very fiercely, then Liu Sanyi has no way, after all, they are not very clear about the situation in the city, and at the same time, it is impossible for artillery to be like modern guided missiles. It is impossible to accurately land the shell in the place where it has been changed, and there is no such high-tech weapon in this era.

And for the enemy, Liu Sanyi's goal is also very clear, that is, to salute first and then soldier, use the time to build the road to negotiate, and then send troops at a very fast speed, quickly occupy, and the means must be fierce, so that the other party is afraid, only in this way, can the other party's psychological defense line be destroyed at the fastest speed, so as to surrender the army without a fight, Liu Sanyi does not want to destroy such a city, what they need now is not only the population, but more knowledge and technology, only these things, can make the Black Iron City continue to develop.

The preparation of the process is underway, Liu Sanyi arranged a team of 3,000 people to open up a road in the deep mountains and old forests, and sent a group of envoys to communicate with the city, on the one hand, to persuade the other party to surrender, on the other hand, it is also to obtain information, understand the layout of the city, and the surrounding sphere of influence, after all, it is really a very troublesome thing to look for a headless fly like Liu Sanyi and them, if you can get some information, know the situation of the surrounding cities, That is undoubtedly much more convenient for Black Iron City.

Through more than two months of you coming and going, Black Iron City did hear some very important information, first of all, this is the city, the locals call him Picheng, because to the north of him is a mountain, the mountain is very tall, in which lives a very huge monster, his body is now this mountain, but also the forbidden place of the city, so no one dares to enter, the locals respect this monster, so they named their city also named the city, hoping that this monster can bless them.

This kind of totem worship from the primitive is obviously a bit backward and the times, but this does not mean that Picheng does not have a heritage in the field of science and technology, because there is a large amount of natural gas around Pishan, so the use of natural gas by Picheng people is still retained, and there is also a power station in the city, which can carry out the simplest power generation, is a self-sufficient city, and even in the field of power generation, its inheritance is a little better than the original Black Iron City, basically the urban population can still afford to use light bulbs.

The population of the entire city is 260,000, of which 40,000 are urban and 220,000 are rural, this data makes Liu Sanyi very satisfied, and it will not be too strong and threaten the status of Black Iron City, and at the same time, it will not be too weak, leading to the loss of civilization, which is a good stage of rule.

On the Skywalker side, the number of the other party is about thirty people, which is about the same as the former Black Iron City, and the number has not surged, which makes Liu Sanyi very relieved, the army's weapons stay in the era of cold weapons, and there is almost a generation gap with the Black Iron City's armament, which makes the strength of the two sides seriously mismatch, and because of this, Liu Sanyi simply asked the envoys to bring a hundred guns from the Black Iron City to Picheng, one to show their strength, and the other to show their goodwill.

Sure enough, seeing that Black Iron City could take out a hundred guns without hesitation, Bicheng's attitude towards Black Iron City immediately changed, which was both fearful and a little excited, the new weapon represents destruction, but also represents science and technology, and the delegation sent by Liu Sanyi finally showed his purpose, before that, they have been engaged in friendly negotiations, so as to talk, and now, after learning the ability of the other party, naturally no longer pretend to be their own strength, but directly open and honest, It is hoped that Picheng can be automatically incorporated into the management system of Black Iron City.

The resistance of Picheng was not so fierce, but chose to let the envoy group of Black Iron City wait for the time being, they Tianwalker need to discuss, the envoy group has no opinion on this, after all, the other party has maintained its independence for hundreds of years, and now it is suddenly going to annex the other party, the other party is naturally unwilling, and it is very normal to need to discuss.

The envoys spent a slightly calm and slightly nervous night in the city, and when the next day came, the leaders of the city summoned the envoys of the Black Iron City to the council hall and told them their decision, they decided to follow the Black Iron City, this decision surprised the Black Iron City envoys, and in just one day, they chose to give up their independence?

Isn't that too easy? Everyone was a little incredulous, after all, the other party is also a big city, with a population of more than 200,000, how could they not even resist, and then choose to give up, at this time, the leader of Picheng, a person surnamed Kong, opened his mouth and said the conditions for surrender, that is, Black Iron City must help Picheng and eliminate their old enemy, Foothill City.

It turns out that in this land, there have always been two cities, one is called Picheng, the other is called Foothill City, the two cities are located around the mountain, since the establishment, there are a lot of exchanges between each other, all the time, the relationship is very good, although there have been some occasional contradictions, but because of the equal strength, no one can destroy whom, so after the war, the two sides chose to reconcile, so there was a very good time.

But later, with the change of strength between the two sides, it was a tragedy that happened more than 30 years ago, when the leader of Picheng learned that a new group of fierce beasts had been discovered around the mountain, and he prepared to take the Skywalker and troops of Bicheng to annihilate this group of fierce beasts and capture Neidan, so as to strengthen the power of Bicheng.

But this news was learned by the people of Foothill City, and the other party directly thought that Picheng was planning to use this batch of Neidan to create a new group of Skywalkers, so as to break the balance of strength between the two cities, and finally defeat Foothill City and become the only overlord in the Foothills, and the fact is that Picheng did think so, although the two sides were peaceful at that time, they both had the ambition of hegemony, so they planned to do this without Foothills City at that time.

At this time, after being known by Foothill City, it naturally aroused the anger of Foothill City, Foothill City saw the opportunity to act, and directly ambushed around the fierce beast community, and waited until Picheng and the fierce beasts fought to the point that both sides were defeated, and when Picheng was about to win, he suddenly killed, directly disrupting the plan of Picheng, this battle, Picheng lost more than five Skywalkers, and the inner Dan of the fierce beasts was also snatched away, which can be said to be a failure, and the strength of both sides has also completely changed. Longlong

Since then, thirty years later, there is no peace between the two sides, in terms of strength, the city because of the sneak attack, the combat effectiveness of the city has been greatly damaged, and the foothill city because of the fierce beast Neidan so the strength has soared, the number of Skywalkers is more than ten more than the city, so the two sides are almost the foothills of the city pressed busy fighting, if it were not for the geographical situation of the mountain is very rugged, I am afraid that the city has already fallen.

Relying on the rugged mountain roads of the mountain, the army is not easy to move, the two sides have insisted on each other for 30 years, the former friendship has become a thing of the past, the two sides are already mortal enemies, each other wants to destroy each other, but because of the terrain problem, both sides are in the terrain of the mountain is in a dangerous position, guarding each other's passes, it is not a simple thing to want to cross, and because of this, the two sides can always exist with each other.

But this balance was broken two years ago, Foothill City got the support of a group called the Holy Alliance, and obtained a large number of musket equipment, which made the two cities that had been in balance for more than 30 years, and now the balance has been broken, before the arrival of the Black Iron City, Foothill City once hit less than ten kilometers away from the city, if it wasn't for the desperate efforts of the soldiers of the city at that time, I am afraid that the city has fallen at this moment.

Therefore, before the arrival of the Black Iron City, the whole city was almost desperate, thinking that it would not take long for the city to be annexed by the foothills, but they didn't expect the Black Iron City to appear in front of them at this time, they saw that the Black Iron City was able to take out so many muskets, and their hearts were lit with hope, and now they heard that the Black Iron City was going to annex them, their hearts were naturally entangled, but instead of being wiped out by the Foothills City, it was better to merge with the Black Iron City.

At least the conditions of the Black Iron City are much better, the Skywalkers can still maintain their rights and old wealth, as long as they hand over the rights of the city, and at the same time, the residents do not need to relocate, they only need to move the experts and books, it can be said that there is no damage to the entire city, so after thinking about it repeatedly, they chose to surrender, and at the same time, they can also use the power of the Black Iron City to destroy their old enemies, which is undoubtedly a quick thing for the city, Therefore, they demanded that Black Iron City must agree to their request.

And they didn't know that the Black Iron City itself had a deep relationship with the Holy Alliance, and at this moment they heard that the minions of the Holy Alliance had reached here, and they couldn't help but be surprised in their hearts, and at the same time there was a burst of ecstasy, it turned out that in this big mountain, there was not only a city, but also a city of the same size, and the two cities combined, that is, a population of 500,000, which would greatly increase the strength of the Black Iron City.

The envoys immediately told Liu Sanyi the news, and Liu Sanyi immediately summoned Shu Han and others to a meeting in the Black Iron City to inquire about the next steps, most of the people, including Shu Han, said that they should agree to their conditions, so that they can peacefully receive all the resources of the city, and at the same time get the support of the city, there is no need to have hatred because of the war, and more than 200,000 people can be obtained, and at the same time, they can also hit the minions of the Holy Alliance in the deep mountains and old forests, and reduce their strength, which is for the Black Iron City, It's a good thing to kill two birds with one stone.

The result of the meeting was finally determined, after all, other options other than this choice were not the best, Liu Sanyi immediately ordered the envoys to restore the city, and at the same time sent twenty Skywalkers and more than two hundred officials to take over the administrative power of the city, and at the same time invited the Skywalkers to the Black Iron City for a meeting, on the one hand, to formally discuss how the two sides should start a war with Foothill City, and on the other hand, to transfer these old rulers, so that the officials of the Black Iron City could receive all the resources in the city more smoothly.

In this regard, Pi Cheng did not have any objections, since they had already decided to surrender, they naturally knew that the other party did not have much trust in them, and it was good that they did not directly seize their families to threaten them, on the other hand, they also wanted to see with their own eyes how powerful Black Iron City was, and this was also the purpose of Black Iron City.

First form an alliance, and then wait for the foothills of the city to be eliminated, the city of Picheng backstabbed the Black Iron City, this kind of thing is not impossible, and now invite them to the Black Iron City, let them see the level of science and technology of the Black Iron City, you can let them dispel this idea, in order to achieve this purpose, Yang Wangdi in the city of Picheng a week before the arrival of the delegation, he ordered the Black Iron City up and down to rectify, clean, to ensure the cleanliness of the Black Iron City, and at the same time temporarily install 10,000 street lamps on the street to ensure the city's lighting system.

In fact, if you can, Black Iron City really wants to put this meeting in Joaquin City, after all, it is the best scenery in the city owned by Black Iron City, but because Joaquin City is too far away from Picheng, the distance is about four hundred and fifty kilometers, and it will take at least two days to come over, and it is too late in time, so I finally chose to give up.

However, although the Black Iron City is not a particularly beautiful city, but as the construction of the Black Iron City for more than 300 years, the city still has a very distinctive beauty, compared to the rugged city built on the mountain, the Black Iron City, as a plain city, shows the city's depth and sense of history, with an innate majesty, enough to make the city believe that this is a strong strength that is comparable to the Holy Alliance.

On the other hand, the people sent to Picheng stepped up and began to take over all the rights of Picheng, and counted the population of Picheng, some of whom had professional knowledge, and immediately began to move to Joaquin City and Black Iron City to assist in the latest research work, while the others did not move for the time being, and the road was finally built after a month, and the representatives of Picheng also successfully came to Black Iron City, and the two sides began to formally discuss the plan to attack Foothill City.

In this matter, Liu Sanyi didn't pay special attention to it, according to Bicheng's statement, Foothill City did not completely join the system of the Holy Alliance, and the weapons obtained were very limited, not very much, but compared to Picheng, the weapons were advanced, but compared with the hot weapons corps in Black Iron City, the difference between the two was still very far.
