The reason why Feng Chou had chosen the master-level arcana materials of the School of Alchemy and Evocation was to acquire the knowledge of building a Mage Tower.
To build a Mage Tower, one had to be proficient in the master-level knowledge of Alchemy and Magic Architecture. However, just being proficient in Magic Architecture was not enough to build a Mage Tower. One also had to master the technique of Evocation's Elemental Pool.
The Elemental Pool was the energy core of a Mage Tower. Without it, a Mage Tower would be like a car without an engine, just a pile of scrap metal.
Feng Chou chose to build the Mage Tower on top of a thick mountain between the town and the dragon's den.
He summoned all the mid-level and above magic engineering teams to the foot of the mountain and set up a temporary camp there.
Feng Chou assigned the dozens of large-scale engineering constructs to the magic engineering teams.
With enough Stone to Mud and Mud to Stone scrolls, it only took them a few hours to build a spacious road from the foot of the mountain to the top.
In the next half a month, about a quarter of the height of the mountain chosen by Feng Chou was completely flattened. The engineering teams then dug a deep foundation from the flattened platform. A huge foundation pit was dug all the way to the foot of the mountain and even deep into the foundation of the island.
The Mage Tower was like an iceberg on the surface of the sea. The tower above the surface was actually only a small part of the entire Mage Tower. The underground foundation was several times higher than the height of the Mage Tower and dozens of times larger in volume.
After the foundation was dug, the engineering teams inserted a large number of arm-thick black steel bars into the foundation and poured in a large amount of special alchemy cement. The alchemy cement used as the foundation of the Mage Tower was different from the ordinary cement on the market. It was a low-level magic item. Not only was it far stronger than granite, but it also had a certain degree of elasticity. Even a big explosion caused by a level-nine spell would have a hard time destroying this foundation.
The foundation was poured layer by layer, and almost half of the mountain was filled with alchemy cement.
In the process of building the foundation, the engineering team left a space for the fourth floor of the Mage Tower in the center of the foundation.
Under the effect of the spell, the alchemy cement quickly solidified. The magic engineering team began to apply a brand new material around the hole in the center of the foundation. This material was a mid-level alchemy composite material. When it was applied, this material was very soft, like high-quality ooze. When it was applied, Feng Chou only needed to use a mid-level alchemy spell to make the ooze harder than black steel. It was also very tough and had a certain degree of elasticity.
After the alchemy coating was hardened, Feng Chou began to use even more precious alchemy mixers to draw a magic circle on the coating.
The magic circle was completed and activated, but it didn't cause any changes. Next, Feng Chou asked the engineering team to apply another coating …
Next, he applied the coating, drew the magic circle, activated it … After repeating this process over a dozen times, these magic circles finally showed their usefulness.
Intense magic waves seeped into the foundation of the alchemy cement and spread down the mountain. In the end, the entire mountain, including part of the island's foundation, was strengthened by magic.
Unfortunately, because there was no more magic energy to maintain it, the magic circle only activated for a moment before it stopped working.
Feng Chou nodded in satisfaction and gave a new order for construction …
Building a Mage Tower wasn't a simple task. An ordinary Master Mage Tower architect might need seven to eight years and experience countless failures before successfully building a Mage Tower.
With the help of Qiankun Pagoda, Feng Chou succeeded in drawing all the magic circles on the first try. Even so, he spent three years and more than a billion crowns of magic materials to finally complete the Mage Tower.
If an ordinary Mage Tower had been built by an ordinary architect, the cost of materials alone would have increased the cost of the Mage Tower by fifty percent.
Fortunately, Feng Chou's two merchant fleets had brought him a huge profit of more than three billion crowns in the past two years.
What was strange was that after the Mage Tower was completed, Feng Chou didn't immediately use Rune Awakening to create a Tower Spirit for the Mage Tower. He stopped the construction of the Mage Tower and began experimenting with the incomplete Mage Tower.
Feng Chou was busy because he wanted to modify a spell, a 9th Tier Spell, "Rune Wisdom Awakening"!
Although Rune Awakening could also be used to create a Tower Spirit, it was actually a defective product. This could be seen from the name of the spell.
The real spell used to create the tower spirit was a legendary spell, "Tower Spirit Awakening".
Unfortunately, Feng Chou didn't know this legendary spell, and he didn't know a legendary mage who could cast this spell for him. Even if he knew such a mage, he wouldn't let someone else awaken the Tower Spirit for him. This was because it was like handing over the keys to your house to someone else. No, it was even more serious than that.
This was because the mage who awakened the Tower Spirit had higher priority than the mage who awakened the Tower Spirit.
The Tower Spirit created by Rune Awakening had limited intelligence and was very rigid. Its functions were far inferior to the Tower Spirit created by Rune Awakening.
Feng Chou had a deep understanding of the rigidity of the Tower Spirit created by Rune Awakening. When he was still studying at Antalya Mage Academy, he had experienced the rigidity of the Tower Spirit. When he replaced Mr Pei Di to take control of the Mage Tower, he had a deeper understanding of the Tower Spirit.
This rigid Tower Spirit was obviously not what Feng Chou wanted, so he turned his attention to Qiankun Pagoda.
Feng Chou asked Qiankun Pagoda to create an artificial intelligence for him to replace the Tower Spirit.
However, Qiankun Pagoda told him that although he could create an artificial intelligence with high intelligence, a pure artificial intelligence wouldn't be able to control the powerful spell functions of the Mage Tower.
Qiankun Pagoda's suggestion was to combine the Tower Spirit and the artificial intelligence. The artificial intelligence would strengthen the Tower Spirit's intelligence, and in turn, the Tower Spirit would help the artificial intelligence control the spells of the Mage Tower.
Following this train of thought, Feng Chou really came up with a solution.
The Rune Awakening spell was a very ancient spell. It was first invented to give some powerful constructs intelligence.
Later, some cautious archmages tried to use this spell to awaken the Tower Spirit.
When the Rune Awakening spell was first invented, it required the use of a recently deceased intelligent creature's brain as the casting object.
The principle of the spell was to use the power of magic to copy all the structures of the intelligent creature's brain, and use the power of magic to construct a virtual brain. Then, with this virtual brain as the core, the construct would be given intelligence similar to that of an intelligent creature.
In the Arcane Era, an arcanist improved this spell and eliminated the casting object of the "fresh intelligent creature's brain". However, the principle of the spell didn't change fundamentally. The arcanist just embedded the model of the "fresh intelligent creature's brain" directly into the spell structure. When casting the spell, the spell directly extracted the model of the fresh intelligent creature's brain from the structure and created an identical virtual brain.
The difference between the two was probably like the difference between photocopying and printing.
Since this spell could copy a human brain, could it copy an artificial intelligence that was simpler than a human brain?
It should be possible!
After spending half a year, Feng Chou finally understood every detail of the ninth-level spell. On this basis, he restored the original version of the Rune Enlightenment spell, which required a "fresh human brain" to be used as a spellcasting item.
After restoring the original version of the spell, Feng Chou tried to use the artificial intelligence to replace the fresh human brain as the casting object.
The result was, of course, failure!
This spell itself was designed to target the brain of an intelligent creature. To change the object of replication, it was necessary to make a comprehensive change to the spell model.
Fortunately, after the previous work of reversing the original version, Feng Chou was already very familiar with this spell. Therefore, he only used half a year to design a new spell model.
Next, he went through experiments, failures, improvements, experiments again, and failures again … After this cycle of half a year, he finally succeeded in creating a magical artificial intelligence!
After testing, the intelligence of this magical artificial intelligence was exactly the same as the original intelligent brain. It could also control various spells in the Tower Spirit like an ordinary tower spirit.
After the spell improvement was successful, Feng Chou personally activated his Tower Spirit.
But he never thought that the activation of the Tower Spirit would attract the Amazons …
