Just because an elder was injured, all Simona's mercenaries had to be buried together, this ruthless approach couldn't help but make Song Lingshan shudder, although for the time being, Wu Song didn't seem to pose much of a threat to the Blood Feather Imperial Family, but Song Lingshan still had a sense of luck, she was very glad that she didn't go to the opposite position with Wu Song, otherwise she would provoke such a desperate guy, Song Lingshan felt that even if she had the protection of the royal family, she was afraid that she would not be able to sleep every night.

"Wu Song." Song Lingshan smiled a little reluctantly and said, "Although I say that I admire your dedication to avenging your friends, there are some things I must remind you, that is, the price of crystal shells is not cheap, even if we are more familiar, I only ask you for a cost price, but 30,000 crystal shells together, you still need to pay a lot of money." ”

"No matter how expensive it is, there must always be a price." Wu Song looked at Song Lingshan with a smile, he knew very well how high the value of the crystal cannonball was.

"If you buy it with crystal coins, I think I can give you the price of 8,000 crystal coins each, if you know the market, you should know that the price I gave is already quite cheap." Song Lingshan pursed her lips and gave the price of eight thousand, probably because she was afraid that Wu Song would be too expensive, so she explained two more sentences.

"The price you gave was fair." Wu Song listened to Song Lingshan's offer and nodded, he had been in contact with Mari Delong in the imperial city before, and after he went back, he spent some time trying to understand the market of crystal cannonballs, and learned that the crystal cannonballs of the Blood Feather Imperial Family were basically not less than 12,000 crystal coins for sale, and now Song Lingshan gave a price of eight thousand, Wu Song estimated that it was just like Song Lingshan said, this was already the cost price. But even so, I thought that the current economic strength was not able to pay such a huge amount of money, so this guy smiled, looked at Song Lingshan and asked, "But to be honest, I don't have much money now, I don't want to use crystal coins, is it okay to exchange things?" ”

"Something for something?" Song Lingshan was slightly surprised when she heard this, and her brows furrowed slightly, from her point of view, this time Song Lingshan wanted to get closer to Wu Song in a pure sense, so she didn't think about what to earn through trading, but Song Da Beauty didn't want to lose too much, this time the transaction was a private transaction, and it was very likely that her father was the emperor who paid for it in the end.

And for their faction, 30,000 crystal cannonballs represent a small number, especially at the critical moment when this mutant insect is about to attack, it can be said that Song Lingshan can grit her teeth and pull out such an important strategic material as 30,000 crystal cannonballs to Wu Song, which is already quite a face for Wu Song.

Her original intention was to let Wu Song pay a cost to buy all the crystal shells, and then the royal family seized the time to use the principal given by Wu Song to buy the raw materials for making crystal shells, and strive to make up for the sold batch of crystal shells before the mutant insect natural disaster began, which is equivalent to Wu Song giving a material money, and the royal family helped to make it, to put it bluntly, the royal family just sold Wu Song a favor and made a handiwork, but now Wu Song said that he wanted to produce materials, which made Song Lingshan a little worried.

She knew that Wu Song should have a lot of excellent resources on hand, but the question was whether the resources in Wu Song's hands could play a role in the upcoming battle between humans and insects It was still unknown, and exchanging important strategic materials for some materials that would not play a role for a while was quite unfavorable for the current royal family, the mutant insect disaster was about to begin, and the major cities were actively rebuilding, which also meant that at this moment was at the peak of using money. Song Lingshan didn't want to pay for Wu Song's exchange this time, but it was precisely because the mutant insect natural disaster was coming, Song Lingshan didn't want to offend Wu Song at this time, she hesitated for a moment, then gritted her teeth and asked, "Wu Song, what materials do you want to exchange?" ”

Although Song Lingshan finally asked Wu Song what to exchange, but Wu Song looked at her expression and didn't know what this little girl was thinking, this guy showed a playful smile, and wanted to tease Song Lingshan, and then pursed his lips, showing a bitter look and said, "You know, I only recently became the city lord, although the Mu family also gave me some rewards before, but my Tailing City is being expanded recently, and there are many places where money is used, so the money is invested not to mention, and a lot of good materials have been put on." , I just wondered... Speaking of this, Wu Song deliberately dragged out a long note, he pursed his mouth, and looked at Song Lingshan with an extremely expectant gaze and laughed dryly.

As soon as Song Lingshan saw Wu Song's virtue, she became more and more virtuous, but her guess was true, this Wu Song really planned to use garbage materials to deceive crystal cannonballs, and when she thought of this, Song Da Beauty's ruddy cheeks also became a little green.

Seeing that Song Da Beauty's face was getting worse and worse, Wu Song also knew that he was almost joking, he pursed his mouth, took out a small round ball from his pocket, handed it to Song Lingshan and said, "I plan to exchange a hundred of these things for you for 30,000 crystal cannonballs." ”

Song Lingshan looked at the small white ball in her hand, shook it lightly a few times, and felt that the ball seemed to contain something, she glanced at Wu Song hesitantly and asked, "What is this?" ”

Wu Song smiled and pointed to the white ball and said, "There is something inside, you can open it and see it yourself!" ”

Song Lingshan nodded slightly, he was a little curious and pinched the white ball in his hand a little harder, only to hear a slight snap, the white ball split into two halves, and a small golden oval thing appeared in front of Song Lingshan.

"What is this?" Song Lingshan was even more surprised after looking at the golden yellow thing in her hand, to be honest, she didn't know what this little thing in her hand was for, which was similar to the pills made by the alchemists, she only felt that this little thing was crystal clear and beautiful, and the glass-colored light looked like life.

"This is a worm egg, a golden devil fly egg with the breath of life, as long as it is hatched properly, it should be able to hatch a golden devil fly, I plan to exchange this for your 30,000 crystal cannonballs, what do you think?" Wu Song slowly told Song Lingshan about the origin of the little thing in her hand and Song Lingshan.
