Then Emperor Gou Chen asked very humbly: "Cui Sixian's nephew, but I don't know if you have any good proposals for defending the demon clan?" ”

Cui Si thought for a moment, and then said solemnly: "I am new here, and I don't know much about Yu Chentian's situation, so I shouldn't be pointing fingers. But since Your Majesty has asked, I will talk about it according to some of the situations in the Four Seas Dragon Realm, whether it is right or not, and please bear with me! ”

"Virtuous nephew, your achievements are obvious to all, your ideas must be good, we are all listening!" Emperor Gou Chen hurriedly laughed. Then, he really showed a deferential look, and even the generals around him became serious, ready to listen to Cui Si's high arguments.

Cui Si smiled modestly and said, "Don't you dare to be it, it's just nonsense!" ”

Then Cui Si's face was solemn, and he began to say: "Although I have not seen the demon clan of Yu Chentian, it is unchanged. I think it's similar to the demon clan in the Four Seas Dragon Realm, they all win by quantity, the single combat power will not be very strong, and the equipment of the demon clan is also very poor, yes or no? ”

"Yes, indeed!" Emperor Gou Chen nodded and said, "If the demon clan is alone, they are not our opponents at all, but their number is too terrifying, and they are often hundreds, or even thousands of times more than ours. Therefore, despite the advantages of geography and people, we have to pay a heavy price to repel it. ”

"Hmm!" Cui Si said solemnly: "I have also encountered such a situation in the Four Seas Dragon Realm, and for this reason, my countermeasure is to build a strong Xuantie city defense. Thousands of miles long, thousands of feet high, on which are densely covered with dragon cannons. Such a city defense can be called impregnable, as long as there is a sufficient supply of cannonballs, almost no demon clan can approach. I don't dare to say more, the army of hundreds of millions of demon clans can easily resist! Even if the enemy dispatches a hybrid master, at most it will destroy one of the sections, and it is difficult to completely destroy it.

"Hehe, I already knew about the city defense of Chen Tangguan!" Emperor Gou Chen smiled slightly, and then he suddenly said in embarrassment: "It's just that we can't learn from it." Although Yu Chentian is richer than you, and he can barely build two or three thousand-mile-long steel city defenses, there are too many places we need to defend, and without fifteen such city defenses, we can't block the attack direction of the demon clan at all. And we must not abandon other places and focus on defending a few, so this matter can only be stopped. ”

Emperor Gou Chen then continued: "It's your dragon pattern cannon that has given us a lot of inspiration, and I'm not afraid of your jokes, in fact, I secretly purchased a batch of dragon pattern cannons from your Four Seas Light Realm, and the effect is very good, but the quantity is too small, I don't know if you can sell us more?" ”

Cui Si actually knew about this for a long time, and he also acquiesced to it, otherwise, no one in the Four Seas Dragon Realm would dare to disobey his will and sell such an important thing at will.

Now that Emperor Gou Chen admitted this matter so calmly, Cui Si naturally wouldn't be surprised, so he smiled slightly and said briskly: "No problem, I still have millions of dragon pattern cannons in the warehouse of the Four Seas Dragon Realm, and the city defense there can't be used so much, I can also let them dismantle the city wall and supply it to you first." In addition, in the future, those craftsmen in the Four Seas Dragon Realm will do their best to make powerful dragon pattern cannons for you! Fight to arm your defenses in full. ”

"Oh, that's great, you've done us a great favor!" Emperor Gou Chen was suddenly overjoyed and said, "How can I thank you?" ”

"Don't worry about this!" Cui Si smiled slightly, and then said: "The steel city defense is actually very necessary, because it is much stronger than the ordinary stone city defense, and the stone city defense can only barely resist the impact of the Da Luo Jin Immortal, once the Mixed Yuan Golden Immortal makes a move, it can be completely shattered at once, and there are many talents in the demon clan, and the Mixed Yuan Golden Immortal doesn't know how much is hidden." Once they join the siege, it is bound to cause heavy casualties. Therefore, I still recommend that you desperately build the Xuantie City Defense. ”

"This...."When Emperor Gou Chen heard this, he immediately frowned and said, "I just said, it's not that I don't want to build, it's really not that there are so many dark iron and high-grade materials?" ”

"Hehe~" Cui Si smiled slightly, and then secretly said, "You don't have it, but I do." When Emperor Gou Chen heard this, he was taken aback, and his eyes were about to pop out.

However, after all, he was the Supreme Emperor of Heaven, and he knew that this matter was very important and not suitable for discussion in public, so Cui Si told him in the form of rumors. Of course, Emperor Gou Chen would not make a mistake, so he immediately asked in a voice: "Virtuous nephew, how many materials do you have?" ”

"Not to mention fifteen thousand miles of city defense, even twenty can I also supply!" Cui Si said proudly.

Cui Si didn't brag at all when he said this, the loess in his natal space has not stopped decomposing garbage for a moment in the past hundred years, even if it is non-stop takeout, there is still a lot of backlog.

Because Cui Si didn't dare to be too presumptuous in takeout, which would not only lower the price, but also easily attract the attention of people with intentions, so he secretly controlled the amount of shipments, and over time, he accumulated a mountain of various low-level raw materials.

Although these things are not valuable, they can't hold a lot of money, and they won't depreciate, so Cui Si is well preserved. When it really can't be piled up, it is secretly buried in the barren mountains of the Eastern Emperor Realm.

Originally, Cui Si didn't want to release these things so early, but today Emperor Gou Chen showed such a high level of sincerity, Cui Si was really embarrassed not to do his best. Therefore, these things were taken out, one was to repay the favor of Emperor Gou Chen, and the other was to take the opportunity to make a profit.

Emperor Gou Chen is not a stingy person, he will definitely be grateful for such a big benefit from Cui Si, and with his identity, he can take out something casually, which is enough for Cui Si to eat.

After listening to Cui Si's words, Emperor Gou Chen was suddenly pleasantly surprised. He knows the terrible thing about the defense of the Xuantie City, if there are really more than ten or twenty cities to protect Yu Chentian, then he can almost be called impregnable here, even if the demon army is fierce, he is not afraid.

If this comes true, then his subordinates don't know how many fewer people will die, and his strength will also rise, and he may even be on a par with the Jade Emperor. In the face of such a big benefit, how could he not be surprised?

Emperor Gou Chen immediately realized that this was a once-in-a-lifetime opportunity, so he immediately stood up and said solemnly: "You guys drink first, and Cui Sixian's nephew and I will go to the back to change clothes!" ”
