Originally, Wu Song didn't care too much about how the two sides exchanged things, but when it came to the exchange of items between the two sides, a thing called the steel city defense structure that Ma Delong took out aroused Wu Song's interest.

This thing is specially used to strengthen the defense of the city wall and enhance the load-bearing capacity of the city wall, according to Ma Delong, if the fourth-level city uses a steel city defense structure, its defense ability can reach the level close to the third-level city, and the load-bearing capacity is to surpass the third-level city, this kind of thing makes Wu Song very interested.

Although the Tailing City he owned was only a fifth-level city in terms of scale, Song Ruizhen promised him that the city defense of Tailing City would be upgraded to the fourth-level standard, and if the steel city defense structure was used, it would be equivalent to Tailing City having a defensive capability close to that of a third-level city, and it had a load-bearing capacity that surpassed that of a third-level city.

City defense is important, but the load-bearing capacity of the city wall is also extraordinary, you must know that those magic cannons used for defense are placed on the city, and those huge magic cannons are all extraordinary, which is a lot of pressure on the city wall, and the load-bearing capacity of the third-level city undoubtedly means that more magic cannons can be placed, which is quite important for the defense of Tailing City.

And only with a stronger defense capability will a safe and stable living environment be created, more merchants will enter the city to set up shops, and more residents will choose Tailing City to settle down, which also means that Wu Song, the city lord, will obtain more taxes and have more wealth, and this kind of thing closely related to his own interests will naturally easily attract the attention of Comrade Xiao Wu.

"Commander Mari Delon, can you sell me some of your steel city defense structures as well?" After hearing Mari Delon's offer clearly, Wu Song felt that this offer was still within the affordable range, so he did not hesitate to send a purchase intention to Mari Delon. And when he interjected, Meng Fat Man on the side was a little unhappy, he couldn't figure out what the relationship between this guy who had been eating with his head bored and Mari Delon, but since he could sit here and eat, Meng Fat Man felt that the other party should also be a person with an identity, before he found out the bottom of the other party. This guy didn't mean to turn his face directly, he just looked at Wu Song silently.

"You're also going to have a steel fortification?" Mari Delong was stunned when he heard Wu Song suddenly say that he wanted a steel city defense structure, he was a little puzzled why Wu Song wanted this kind of thing, but since Wu Song didn't say it, he didn't take the initiative to ask, but thought about it for a while and said, "Brother Wu, this thing can only be used to strengthen the city wall, and since we are trying to resist the insect plague in the near future, all the engineering materials are not sold out, but used to change crystal cannonballs." ”

"That's what I want!" Wu Song nodded, he could naturally hear the reminder in Ma Delong's mouth, this guy thought about it, and felt that it should not be very difficult to ask the Lord Mu to help get some crystal shells, so he smiled and said, "What I want should be no less than this Brother Meng, let's leave a contact information later, I will calculate the specific amount and tell you later, as for the change method, it will be according to the ratio between you and Brother Meng just now." ”

"That's fine." Mari Delong laughed, Wu Song's intervention was also a surprise for him, this time the insect plague situation was extremely severe, he naturally hoped to get as many crystal shells as possible, but he was cool, but that Meng Fat Man was not happy, this guy thought that Wu Song was also another businessman called by Mari Delong, so he pouted and said, "Master Mari Delon, this business is for us to talk about first, as the so-called first come, first come, first come, even if this brother wants to trade, should your brother also follow me first." ”

"That's natural, that's natural." Ma Delong glanced at Wu Song apologetically, and then said, "Brother Meng, you can rest assured, this time we have a sufficient supply of goods, and there is absolutely no problem with the numbers you want." ”

"Not necessarily!" Meng Fatzi pursed his lips slyly and said with a smile, "Captain Maridelon, I think there should be a need for further cooperation between us, brother, you also said before that you hope we can increase cooperation, this proposal is quite good, in my opinion, so be it, I can call the shots to increase the exchange of some steel city defense structures, the number is three times the amount we talked about before, and I promise that I will not lose you in terms of crystal shells." After Meng Fatzi finished speaking, he glanced at Wu Song on the side with some pride, although he hadn't figured out who this young man was, but since the other party was also sitting in the hall on the first floor of Dinghong Building to eat, Meng Fatzi pondered that the other party should be about the same as his own identity, since everyone was half a catty and eight taels, he wanted to teach the other party a little lesson, so that the young man knew that sometimes he should not interfere.

Mari Delong listened to Meng Fatzi's words, and also understood what the other party meant, which made him embarrassed, Wu Song is a good friend who has recreated the Hero's Wings, but this batch of crystal cannonballs is also extremely important to him, if he can't get a sufficient number of crystal cannonballs, then Hero's Wings and Olimo City are likely to become history under the crazy attack of the swarm, and if Meng Fatzi triples the exchange volume, the steel city defense structure he has on hand will not be enough to supply two, He glanced at Wu Song with some embarrassment, but saw that Wu Song just smiled and waved his hand at him and said, "Commander Mari Delong, you just need to supply this Brother Meng first, and my ones will be fine if you slow down a little longer." ”

"That's embarrassing." Mari Delong smiled bitterly and apologized to Wu Song, while Meng Fatzi showed a villainous expression, he felt that this time the confrontation was obviously won by himself, and the kid who didn't know the rules and didn't know the height of the sky also tasted the bitterness, but soon Meng Fatzi's mind changed drastically.

Wu Song didn't get too entangled with Meng Fatzi on the issue of who got the right to trade first, this guy laughed, and then he ate and drank like a starving ghost reincarnated, and Meng Fatzi showed a little disdain for Wu Song's almost discounted eating appearance, but soon this guy's eyes widened, because he found that a few gentlemen led by Song Zhiyun were walking towards this side, and just when Meng Fatzi pondered why he was wandering around the hall on the first floor as Song Zhiyun and others, found that Song Zhiyun and others actually walked to their table.
