During the period of overhauling Lei Yi's merchant ship, Lin Feng urgently mobilized a batch of goods, mainly including a large amount of grain and various daily necessities. Well, according to the information provided by Rey, the tribal emirate has a poor grain harvest this year, and there are already signs of food shortage, and their original purpose was to go to the orc empire to buy food, who knows......

The tribal emirates are relatively rich in mineral resources, but the land is much poorer, and when the year is bad, food shortages will naturally break out. This is also one of the reasons why Lin Feng values trade with them, a seller's market, no matter what he does, he will not lose.

Moreover, Lin Feng is now vigorously recruiting refugees, and in the future, nearly 300 square kilometers of plains in the central part of Nanlin Island will be reclaimed into farmland. When the time comes, it will be too late to open up a trade route for grain trading, and now is the right time to open the way for the tribe. What's more, Lin Feng is also very interested in the mineral resources here.

After arranging these tasks, Lin Feng once again ascended Sunset Mountain, where he was going to build his first mage tower. This time he went to the Mage Guild, he bought the drawings of the Mage Tower that the Mage could build, and before this voyage, Lin Feng had to choose the address and let the craftsmen dig the foundation.

As for the luxurious and exaggerated mage tower drawings given by Teacher Carrido, Lin Feng also wrote to him to ask him later, and Carido also wrote back to explain: It turned out that those were the construction drawings of the "Floating Mage Tower", which were used to build the Legend Level Mage Tower.

The Floating Mage Tower, as the name suggests, can rise in the air, which means that this kind of Mage Tower can move freely. Generally speaking, a legendary mage will have such a mage tower, well, after the legendary mage opens up the half-plane, he will put it into the half-plane, and release it when he needs to use it.

Of course, that kind of mage tower was still too far away for Lin Feng, but he also had to have his own mage tower now. After all, after being promoted to the Great Mage, every time he meditated on magic, he would strongly attract the magic elements around him, well, the rich magic elements were not something ordinary people could bear.

According to the drawings in his hand, Lin Feng chose a place in Sunset Mountain, near the crater of the extinct volcano of Sunset Mountain, condescendingly, at a glance, the Sunset Fort at the foot of the mountain and the Crescent Harbor further away were within sight.

If the Mage Tower is built, the Arcane Eye on the tower will monitor the fifty-nautical-mile radius, which is crucial for the maritime early warning defense of the Crescent Harbor. If Lin Feng's mage level was further advanced, then the arcane eye's alert range would be expanded. What is this, this is a fantasy version of Super Radar!

The large mage-level mage tower is: one underground and five above ground. The basement layer is the energy pool, which is generally one of the four basic elements of earth, flame, water flow, and air, since Lin Feng's mage tower is built on the crater, its energy pool attribute can only choose the fire element.

The ground floor of the Mage Tower is divided into three parts, and the entrance occupies a quarter of the area is the welcome hall and guardhouse. The back of the hall is divided into two parts, the larger area is used as a handyman's residence, and the smaller part is used as a storage room, which stores some daily necessities and so on.

On the second floor of the ground floor is the living quarters of the magic apprentices in the Mage Tower, as well as classrooms, apprentice laboratories, recreation rooms, and more.

The third floor is the public library of the Mage Tower, the residences of the mages attached to the Mage Tower, as well as the public alchemy room, enchantment laboratory and other auxiliary staff workshops. Of course, there are also several private laboratories that are especially available to subsidiary mages in need.

The fourth floor is the residence of the owner of the Mage Tower, which is the most heavily guarded and dangerous place in the Mage Tower, with living rooms, meeting rooms, exclusive laboratories, private libraries, and so on.

The fifth floor is the top floor of the Mage Tower, which is usually built in the style of an attic. It usually has a small light elemental energy pool, which absorbs all kinds of light elemental energy during the day and stores it in the energy pool, and then provides energy to the magic lamps in the mage tower through a special rune network to illuminate it.

Out of practical needs, Lin Feng prepared to add a king-sized magic lamp on the fifth floor as a lighthouse for Crescent Harbor to point out the direction of ships sailing away at night or in foggy days. There is a pool of light elemental energy, well, this lighthouse is simply a model of pollution-free and green environmental protection, and the light is stable, bright and has a long standby time.

Above the spire of the attic is the Arcane Eye, a fusion of Arcane Crystals, Opal, Adamantite and Mithril, and is accompanied by three control crystal balls in the guardhouse on the first floor, the observation room on the third floor, and the reception room on the fourth floor.

Of course, the use levels of these three are also different, which are apprentice, mage, and master. The Apprentice-level Crystal Ball can only provide preliminary warnings, and can be used to observe large moving objects such as various types of ships and needs to be manned.

The mage level is further refined to monitor a certain level of energy response, and then distinguish what kind of creature carries those energies and infer the class of profession they belong to based on their energy attributes.

The Master level is owned by the owner of the exclusive Mage Tower, and has a unique and exclusive attribute limit. It can control the other two crystal balls, and it can also show everything that the Arcane Eye "sees" in greater detail.

Lin Feng modified the standard drawings of the Mage Tower according to his own ideas, of course, he only modified some small details of the interior of the Mage Tower, such as swapping the living room and the living room, changing the number of magic lights, ranking, etc., and he did not change the overall situation such as the frame and height.

Well, the standard drawings of this mage tower have been optimized and improved by the mage union for nearly 10,000 years, and it is already a close to perfect design, Lin Feng simply doesn't have the ability to overhaul and overhaul it, in case he increases the height of the mage tower a little, this internal rune network will inevitably be changed accordingly, but how to change it? He doesn't know anything.

Lin Feng returned to Sunset Castle, sorted out the revised Mage Tower drawings, and then released his calligraphy technique to transcribe a copy. He was going to leave the copy behind and let Linnab call craftsmen to dig the foundation and prepare the materials for building the tower at the location he designated.

In this way, after Lin Feng returned from Xilin Port, he could officially start building his first mage tower. And after the Mage Tower was built, Lin Feng's fleet should almost be formed, and it would be able to take on the task of guarding Crescent Harbor.

At that time, the Crescent Harbor could be officially opened, and Lin Feng's plan to make it a new maritime trade city had taken a firm first step, and when his plan was fully realized, well, Lin Feng should seek a direct territory on the mainland, this is a later story, not to mention it for the time being.
