After taking the Silent City, Gu Feicang went to the warehouse of the Silent City and the treasure house of Hercules as soon as possible, facing a half-step legendary Gu Feicang, although countless terrifying and powerful defensive magic were exerted outside the treasure house of the Silent City and Hercules, they were still dismantled by Gu Feicang one by one, and in the end, the treasures inside fell into Gu Feicang's hands.

I have to say that the accumulation of the Silent City over the years is still quite abundant, and most of the resources, except for those to be used to develop the Cross Empire, are all taken away by Gu Feicang and used as private resources, used to develop the castle space and handed over to the mages, the big goblins to make diamond people, gold people and the like.

After entering this battle, Gu Feicang felt more and more that if he wanted the human race to truly gain a foothold in the Yafa world, instead of relying on a saint-level powerhouse to survive, what he really needed was not much high-end strength, but a strong combat power at the bottom, which was difficult to do whether it was castle space or others, but relying on magic technology, there was no problem at all.

Gu Feicang communicated with the mage of the castle space, the technology of creating gargoyles, stone men, iron men and the like, human beings are not uncontrollable, but they are very complex and need to be simplified, this point, after obtaining the basic technology of the goblin, as long as it takes time to study, it can still be achieved in the end.

Not only that, in the castle space, there is a building, Gu Feicang has never realized its true role, that is, the library, the library, has the power to be able to randomly appear a book every day, because at the beginning, the magic president told Gu Feicang that the cultivation of magicians, especially in the later stage, if they want to become a saint-level powerhouse and comprehend the law, generally speaking, the more they know, the easier it is to succeed, and the cultivation of mages, many times, is the cultivation of knowledge.

Therefore, Gu Feicang basically enters the library every day to see what new books appear, and then starts to read, constantly improving his knowledge.

However, the books that appeared in the library were all random, sometimes, sometimes popular science, sometimes fairy tales, sometimes even gossip magazines, there were really too few things that made Gu Feicang feel useful, and the only time he felt very valuable was because of one of the wine-making books, which allowed him to establish a trading relationship with the dwarves in the early days.

Therefore, even if he would enter the library every day, Gu Feicang really didn't attach much importance to this building.

However, after being reminded by the mage, Gu Feicang found that if there is anything in the castle space that can help the Terran rise, one is the large number of gargoyles and stone people created by the mages, these puppet mechanical troops that obey the mage, or obey the human race, and the other is the library, although the books produced by the library now are not of much use for the Terrans, but when there is enough time for the library to produce enough books, it will play a pivotal role for the Terrans。

Knowledge is power, and it is a truth in any world.

After learning this, Gu Feicang also began to think about finding a way to copy the books in the library to the world of Yafa, and after having decisive power in the future, he would establish a powerful library in the human kingdom to ensure that the human race could rise as a result.

However, in order to achieve this, Gu Feicang also needs to be able to have strong strength, otherwise, the world of Yafa is so big, even if it is a peace-loving elf, it will not tolerate the rise of the human race, and when it surpasses them, if there is not enough strength, I am afraid that the moment this library is built, it will be destroyed by the powerhouses of other races, and even from the human race itself, not necessarily, after all, the inferior nature of human beings, Gu Feicang can't believe it at all.

With a decision in his heart, Gu Feicang temporarily kept this matter in mind, and then began to attack other cities, I have to say that after attacking the Silent City, it was a great deterrent for the entire Northwest Land, especially, those well-informed people, when they learned that Gu Feicang not only attacked the Silent City, but also killed a half-step Douwang powerhouse, they were in the limelight for a while, and the characteristics were manifested in the castle space, and the Force gems and Force crystals began to surge, which also led to the fact that not long after the resources were exhausted, Gu Feicang's hands once again had good resources, and even never recruited a complete sacrifice, the knights are finally full, so that the strength under Gu Feicang's hands is once again enhanced.

Gu Feicang, whose power resources have been strengthened again, is well versed in the truth of the speed of soldiers, and after breaking through the Silent City, he left the griffin troops in charge, and he began to sweep other cities, fortunately, after having the leader class, the Holy Wing Griffin also has the wisdom of Ryan Zoe who does not rain, although it is the appearance of a griffin, but it is also completely able to suppress one side, waiting for Princess Sophia to send someone to take over the Silent City.

I have to say that compared with the Silent City, the other forces are simply chickens and dogs, although this is also due to the fact that most of the forces of the Cross Empire are concentrated in the southeast, but the speed of Gu Feicang's conquest is still too terrifying, almost a day can take down a place, sometimes fast, for example, the distance between two cities is not far, and even two cities can be defeated in one day, this is still because Gu Feicang's leader is still a little less, and it can be used to suppress the lack of troops in other places.

When it came to the end, even Gu Feicang didn't need to attack other cities, the moment Gu Feicang appeared, those cities automatically surrendered, so that in just half a month, Gu Feicang walked the entire northwest of the Cross Empire, this place that has fallen apart since the civil strife in the empire was finally unified by Gu Feicang in the name of the eldest princess Sophia, and became a real third-party force in the Cross Empire, and the east of the second prince and the south of the sixth prince fought against each other。

After half a month, finally, the news that Gu Feicang was still alive and attacked the northwest of the Cross Empire despite the agreement made under the witness of the elves finally reached the battlefield of the undead.
