After speaking, Emperor Gou Chen didn't care how the people below reacted, so he hurriedly pulled Cui Si to the back of the palace.

It didn't take long for the two of them to come to a well-guarded secret room. Emperor Gou Chen directly pressed Cui Si on the chair, and then said excitedly: "Virtuous nephew, this place is heavily guarded, and there are countless prohibitions and protection, and no one can hear the voice inside." Say whatever you want. Tell me, do you really have that much material? ”

"Of course!" Cui Si said solemnly: "I can't lie to you about this matter?" ”

"But how do you have so much material? As far as I know, even if Zhu Rongtian wants to come up with so many materials in one go, it will be extremely difficult, right? Emperor Gou Chen said in surprise.

"Hehe~" Cui Si smiled slightly and said, "I'm sorry Your Majesty, I can't disclose the origin of these materials, if I can say it, I won't discuss this matter with you secretly!" ”

"Understood, understood!" Emperor Gou Chen hurriedly said: "I don't ask, but can you sell me all these materials?" ”

He only cares about whether these materials can be obtained now, and as for the origin, he is too lazy to meddle with things! Anyway, when something is in his hands, it must be his, and no one can take it away. Even if it's stolen goods, he will never spit them out.

Cui Si naturally knew Emperor Gou Chen's thoughts, so he said very sincerely: "Your Majesty, although these materials are not valuable, they are in an astonishing quantity, and they can't be purchased outside at all. The so-called odd goods can be lived, and they can be sold for a large price. However, Your Majesty, you treat Cui Si so kindly, Cui Si naturally can't help but express it. In this way, I am willing to sell it all to you at eighty percent of the market price, and guarantee that you can build at least 20 thousand miles of city defense! ”

When Emperor Gou Chen heard this, he was so happy that he couldn't close his mouth, and he immediately rejoiced: "Is this really the case? You're not lying to me, are you? ”

"Hehe, don't worry, although Cui Si is low, he still knows how to speak!" Cui Si said with a smile.

"Oops, I lost my word!" Emperor Gou Chen excitedly grabbed Cui Si's hand and said, "Virtuous nephew, you have helped me a lot this time!" I will definitely remember your kindness! ”

"Your Majesty is so polite!" Cui Si hurriedly said humbly.

"You're welcome, I'm really grateful to you! With so many materials, you are the only one in the fairy world, and it is a completely monopolistic business. If you have the intention to blackmail, even if it is twice the market price, I will not hesitate to eat it at this threshold of demon invasion! Emperor Gou Chen said gratefully: "But not only did you not take the opportunity to raise the price, but also reduced it by two percent, this favor is too big, don't talk nonsense, you Cui Si will be my benefactor of Yuchen in the future, if someone dares to be unfavorable to you, I Gou Chen will fight for my life, and I will shelter you!" ”

Emperor Gou Chen's words are extremely serious, and it can be seen that he is sincerely grateful to Cui Si.

Cui Si hurriedly smiled and said, "In this way, Cui Si will thank Your Majesty!" ”

"Haha, it should be, it should be!" Emperor Gou Chen smiled heartily, and then his face showed sadness again, and said: "However, the material money for twenty thousand miles of city defense is not a small number, and the top-grade immortal crystals I have accumulated alone are not enough to pay the bills?" Don't know what else you can use to offset your bill? ”

"Absolutely!" Cui Si smiled slightly and said, "Whether it's a high-grade material or an immortal weapon, I want it!" ”

"Oops, so I'm relieved. I'm afraid my treasury will be empty! Emperor Gou Chen laughed.

"Hehe, you're too humble, I don't believe it, you've been the emperor for so many years, and you still have no savings?" Cui Si said with a grin.

"Naturally, I have some savings, but I have been fighting wars here all year round, and my expenses are also large!" Emperor Gou Chen sighed, and then said: "Forget it, no matter what, this time we must also build the city defense." Now, you can pick up the contents of my treasure trove, and I hope you can ship them soon! ”

"Okay, since you're so happy, then I can't be stingy!" Cui Si smiled: "I have a lot of materials on me now, enough to build a few thousands of miles of city defense, I don't know if you have such a big warehouse?" ”

"You're taking it with you now?" Emperor Gou Chen was stunned for a moment, and then suddenly realized: "Ha, I understand, I'm afraid you have wanted to sell me something a long time ago, right?" Hehe, that's fine, I immediately ordered them to prepare the place, and in addition, the construction of the city defense, I also have to ask you! ”

"Hehe, this is simple, I will give you a copy of the city defense map of the Four Seas Dragon Realm, just build it according to that style, the key is the formation above, you can't be lazy, and strive for perfection. As long as the city defense is not broken, relying on a large number of dragon pattern cannons, it can definitely bombard and kill the demon army, and it is useless to come. Cui Si said confidently. As he spoke, Cui Si took out a piece of jade talisman and handed it over.

"Thank you very much!" Emperor Gou Chen hurriedly smiled and said, "With the city defense map, it will be much easier for us to do it." The children below know that this matter is related to their own lives, and they guarantee that no one will dare to be lazy! ”

As he spoke, Emperor Gou Chen took the jade talisman, swept it lightly, and immediately read it thoroughly, and it was indeed the design of the city defense, even including the formula of the materials, and what formation was the best to depict. These are all slowly tested by Cui Si when he built the city defense, which can be described as very precious materials.

Emperor Gou Chen naturally knew the goods, and after reading this recipe, he was even more satisfied with Cui Si, and smiled directly: "Okay, it really deserves to be a steel city defense, with this thing, my Yu Chentian must be solid." Virtuous nephew, since you are so hearted, then I will not treat you badly, come on! ”

As Emperor Gou Chen broke off, the yellow-robed monster immediately appeared in the secret room. Emperor Gou Chen instructed him: "Second brother, take Cui Sixian's nephew to the No. 1 secret vault, the treasures in it are at his disposal, the number is not limited, the level is not limited, as long as he likes it, he can take it all!" ”

"Huh?" When the yellow-robed monster heard Emperor Gou Chen say this, he exclaimed on the spot. Although he knew that Emperor Gou Chen valued Cui Si very much, he still didn't expect to value it to such an extent. You must know that in the No. 1 secret vault of Emperor Gouchen's boat, all the best things are stored, and any one taken out is worth a fortune.

If you give Cui Si a few pieces, then the yellow-robed monster is understandable, but let Cui Si choose, you can take as much as you want? Isn't that too generous? So much so that the yellow-robed monster was stunned on the spot, not knowing whether it was time to remind his eldest brother.
