After the breakthrough in papermaking technology, Su Lun began to arrange for people to copy books by hand as soon as possible, and if the school in Zhenbei City wanted to expand, it needed a large number of books.

Poor quality paper, printing inks, etc. are all problems, and only hand copying can be used. However, this is not a difficult task for those scholars, after all, when there was no printing press, hand-copying was used.

After the paper from the paper workshop was made, except for half of it was sent to the lord's castle, the rest was sent to the academy to use it to copy books. In the past, books used parchment, and the general book could not write many words, and it was very heavy, and the cost was high, but now it has been replaced by paper, and the content of the original dozen parchment books can be easily done in one book.

The first batch of paper is not very large, but after the first batch is made, the second batch of paper is made faster, and the quantity will increase several times. Most of the papers in the castle were sent to the town hall for use in the office to record and report data, as well as various official documents.

Zhenbei City, Academy, after seeing a cart of yellowed paper being delivered, those scholars were very curious about this kind of paper, and soon a steward stepped forward to hand it over.

"Morey, this is the paper that the lord asked us to send, you can confirm the quantity, and then move the paper back when you are done. A middle-aged man walked over and said.

"Is this what the lord said about paper?" asked the man, Morey, as he walked over and picked up a piece of paper. "My lord, let us use this paper to copy books. ”

But this paper is much thinner than parchment, and if it could be written, it would be several times more than parchment in a book. ”

"I don't think this kind of paper is easy to preserve. ”

"Who knows, the lord's order is something that a few of us can refuse?"

"Ladies and gentlemen, this is specially sent to the academy by the lord to let us copy the books, let's just recruit it, let's do it, and move these papers down first. Morey beckoned to the crowd.

Thanks to the efforts of many of the academy's students, the papers were quickly delivered to an empty room.

"Paper is susceptible to moisture, so be careful to keep it dry when storing it. ”

Soon after the paper was distributed, scholars began to use paper to copy books, and when they used it, they found it convenient, although compared with parchment, these papers were easy to break, easy to damage and many other shortcomings, but still widely praised by those scholars.

Suren was holding a freshly completed manuscript book, which had been bound to his request instead of a parchment roll. The surface of the book is a little rough and it looks very rudimentary, but it is much more convenient than the previous parchment scroll.

"Someone!" Su Lun shouted as he put down his book and rushed out the door.

"What do you command, sir?" said one of the guards respectfully.

"Tell Morey that in the future, books will be made in this style, and these books can only be read in the academy, and they cannot be taken out without my permission, and they must not be damaged, and violators will be severely punished, and Morey will be notified to establish a library in the academy for storing all kinds of books. ”

"Yes. The guards were ordered to leave.

With the advent of paper, education at the academy has also become easier, and almost every student has a book, which used to be the only teacher alone. With books to keep track of, these students have also learned a lot faster.

After taking care of the school's affairs, Suren began to focus on other things.

The number of slaves in the territory has been increasing during this time, especially after the Harpy came, because Suren asked Alex to take the Harpy to train and attack the goblins, kobolds, gnolls, and orc tribes in the wasteland.

Zhenbei City obtained a large number of slaves, and the orcs thought that a great battle would cause heavy casualties, and even the orc chieftains were killed in battle, and the remnants of the orc tribe also fell apart, and the half-crippled centaur tribe that was attacked by the orcs also joined Zhenbei City.

The two overlords of the original wasteland suddenly disappeared, and Zhenbei City did not have the ability to occupy the territory of the original orcs and centaurs, which caused a temporary vacuum in this wasteland, and the small and medium-sized tribes in other areas of the northern wasteland began to migrate here and fill this area again.

For these small and medium-sized tribes, this is a once-in-a-lifetime opportunity, in order to compete for these grasslands, plains and other living space, there have been several wars in the wasteland during this time. Suren released the army of Zhenbei City and the newly joined Harpy Banshee to train and upgrade, and capture slaves by the way.

With the military activities of Zhenbei City, the number of slaves in the territory soon exceeded 10,000, of which the largest number were goblins and kobolds, followed by jackals and orcs.

The kobold warlock with the highest chance of appearing is the kobold, and after suffering several losses, the army of Zhenbei City will take out the warlock or shaman as soon as they find them. Due to the increase in the number of slaves and displaced people, the consumption of food in Zhenbei City also increased all of a sudden.

Fortunately, the food reserves in Zhenbei City are sufficient, and there is a harvest altar, so there is no need to worry about food shortages.

After a year of development, Zhenbei City also has a lot of fame in the northern provinces, there should be a lot of bankrupt peasants, small merchants began to come spontaneously, the population of Zhenbei City grew rapidly, remove all the slaves, as well as Jinghu City, Centaur City, the population of Zhenbei City has been more than 22,000 people.

Sufficient labor resources allowed Su Lun to speed up the construction of the Arc de Triomphe, before because of the establishment of Mirror Lake City and Centaur City, Zhenbei City transferred about half of the slaves, and now after a large number of arrests, the number of slaves has skyrocketed, and the construction of the entire Zhenbei City has accelerated.

As the second wonder building in Zhenbei City, and it was also built to praise Suren, it is naturally a top priority. The white marble is mined from the Lotas Mountains and then transported to the north of the town by camel beasts, where it is polished by stonemasons before it is used.

Pieces of marble were polished smooth and smooth, and then dragged by slaves, each weighing a ton, and some of the larger ones weighed more than three tons. The opening in the middle of the three openings of the Arc de Triomphe is 10 meters wide, and the small doors on both sides are also 6 meters wide.

The whole triumphal arch spans the main street of the north city of the city, the Rising Sun Street, after passing through the triumphal arch, is the central square, the height of the door hole is 19 meters, after the completion of the construction of this triumphal arch, it will be the tall building second only to the harvest altar in the north of the town.

The inner wall of the door hole is carved with lifelike reliefs, these reliefs are the picture of Suren's victory over the enemy, from the first gnoll, to the later ice pterodactyl, to the trolls, orcs, etc., many battles, after some artistic processing by those master carvers, even Suren has a feeling of watching an epic.

With sufficient manpower, the construction of the Arc de Triomphe was very fast, and many times Karina and Grace were required to cast various spells to help with the construction, and the arched openings of the Arc de Triomphe were very heavy, and it was very difficult to carry them as a whole with the current human technology, but this was only a little troublesome for wizards.

With the joint efforts of two fourth-order transcendental-level warlocks, this marble, which weighs at least dozens of tons, has been successfully moved, and after the completion of the capping, the construction of the triumphal arch is half completed, and the remaining carvers need to carve the marble.

After the marbles are placed, Karina and Grace will need to turn the clay into stone to fuse the original marbles into a single whole, and when the triumphal arch is completed, it will be a whole whole.

After a lot of construction, a group of skilled carvers were trained, and Suren specially approached Hathaway to make some tools specially used to carve stone, which could make it easier to carve marble. With these tool bonuses, the shape of the Arc de Triomphe can be carved very quickly.

After all the carvings were completed, the triumphal arch was blessed with hardening, which was first used during the Arcane Empire to build the Floating City, and the effect of this spell was permanent. When cast, even a piece of wood becomes as strong as steel.

It is said that at that time, the defenses of those floating cities in the Arcane Empire era could resist the strongest spell of the prophecy system, and the meteorite fell from the sky unscathed. After the Arcane Empire disappeared, later wizards tried to build a floating city, but for various reasons failed, the biggest problem was energy.

Legend has it that every floating city has a Mithic Core to provide energy, but no wizard has ever discovered such a thing, and even the process of making this Mithic Core is unknown.

Unable to build the Floating City, the wizards relented to the construction of the Wizard Tower, and of course there were also wizards who built the Floating Tower, which was built entirely of obsidian and then hardened, which was very hard.

In order to prevent the triumphal arch from being damaged, Suren also attached sclerosis to it, which was not a small job, and even Hathaway was caught by him to work together.

It took a few days for all parts of the Arc de Triomphe to be hardened, but the Arc de Triomphe still had one final step to complete.

Suren followed the stairs in the Arc de Triomphe into the interior of the Arc de Triomphe, where there was a room that was used to store the Spirit Stones. Su Lun took the Battle Spirit Stone from the storage space, the purple Battle Spirit Stone looked very beautiful, and came to the altar in the center of the room, Su Lun took a deep breath, and then put the War Spirit Stone on the base of the altar.
