Chapter 408: The Powerful Magic Crystal Cannon

“Everyone is here! Now I will announce the results of the final assessment. The Human Sword Saint passed the first three stages but failed the fourth. Both the Golden Mage and the High Witch Lord were exceptionally outstanding, having reached the point where they could pass the sixth stage and strive for the seventh—yet unfortunately, they failed to answer the final questions!”
“I hereby declare that the new master of the Sky City is this young person—the only one in nearly ten thousand years to pass all the trials—a genius mage with a firm will and unwavering beliefs!”
Everyone looked at Donald with joy. Donald stood up and bowed to Sera once again.
“Please rest assured, Senior Sera! I will keep your teachings firmly in mind and surely not go down the wrong path!”
Sera nodded in satisfaction.
“Then I can rest easy and entrust everything to you. Now, let me show you, my new master, the main areas of the Sky City!”
First, Sera’s illusion led Donald and the others through a teleportation passage in the hall to the command center at the highest point of the pyramid-like complex in the Sky City.
“This is the control hub of the entire Sky City, responsible for operating all the magic arrays and devices. The most important ones include the levitation and flight systems, as well as the city’s defense system!”
Sera skillfully summoned a virtual panoramic view of the Sky City from mid-air in the sci-fi-style command center. This method of monitoring via arcane arrays was similar to the crystal projections in Donald’s magic ship, but even more powerful. With the virtual divine entity system activated, it could monitor everything within a radius of thousands of miles centered on the Sky City.
Compared to these monitoring arrays, those high-tech surveillance devices on Earth in his past life were utterly insignificant!
“These are the four main arcane towers of the Sky City. As long as a legendary spellcaster resides in any one of them, the towers’ powerful amplification effects can resist invasions by demi-god-level warriors. With these four main towers, along with thirty-two other secondary towers, constitutes the Sky City’s most formidable defense system!”

“Additionally, 120 magic energy crystal cannons are deployed around Sky City. These powerful arcane weapons generate immense energy by inducing high-energy magic crystals or magic cores of level 9 or above to split apart. Each cannon’s individual attack power can match that of a legendary sword saint’s normal attack without using domain skills. When all 120 cannons fire simultaneously, they can instantly destroy everything within a hundred miles, or they can be focused into a single energy beam for targeted attacks—even a half-god dragon’s formidable physique cannot withstand such strikes!”
As she explained, Sera displayed footage recorded in Sky City showing the spectacular effect of all the magic energy crystal cannons firing at once, leaving those present in awe. To Donald, the power of these cannons was akin to the scenes in science fiction movies like Star Wars!
“Of course, though the magic energy crystal cannons are extremely powerful, there are many restrictions on using them! Firing them all at once requires activating 36 arcane towers and one-third of Sky City’s core energy. Meanwhile, when using all the cannons, Sky City must remain in a stable floating or fixed state and cannot enter flight mode at the same time, as excessive energy flow would overload its internal energy transport system and cause damage! Also, after each firing, the cannons need at least three minutes of cooling time; otherwise, overheating of the cannon mechanisms can lead to self-destruction!”
Carlisle, still in shock, said, “Such immense power—almost invincible in the Main Material World!”
Donald shook his head and disagreed, saying, “Although this attack seems powerful, it causes far too much damage to the environment of the Main World. It’s best not to use it unless absolutely necessary! Moreover, though the attack from the magic energy crystal cannons is faster than lightning, the brief preparation time before firing still gives the enemy enough time to dodge! So, the target must be locked before firing—otherwise, it’s just a waste of energy!”
Upon hearing Donald’s words, Sera spoke in high approval, “Exactly! I didn’t expect you to be so sharp. I hadn’t even introduced them yet, and you’ve already analyzed the biggest flaw in these weapons!”
Without being overly humble, Donald followed Sera as she continued to show him other parts of Sky City.
Sky City’s teleportation system was similar to a combination of subways and elevators from his past life, but it utilized spatial conduit principles to allow people to quickly travel to other areas through these conduits.

In reality, not much distance was covered, but due to the rapid teleportation process, it felt as though they had arrived in an instant. This short-distance transportation system and Donald’s magic teleportation gates each had their advantages and disadvantages. The former consumed less energy and, because the pathways were fluid, could transport large quantities of goods like trains or subways, but it could only operate within the Sky City where the pipelines were established. The latter could teleport over any distance as long as it was within the same plane, but it required more energy, and only a limited number of people could be transported at once; for large-scale teleportations, teleportation arrays had to be used instead.

Next came the Alchemy Experiment Area, which housed the largest alchemy factory in the Sky City and a state-of-the-art large-scale alchemy laboratory. The other laboratories were distributed among the thirty-six arcane towers, none of which were as large as this one. After seeing the sophisticated and powerful equipment in the large alchemy laboratory, Donald thought of a question when he noticed the high-level lich nearby. So he asked Sera about the art of lich rebirth.

“I certainly know about the art of lich rebirth. When I was still alive, I was one of the researchers of this legendary spell. Are you planning to help this high-level lich be reborn?”

“That’s exactly right. Senior Chikofield was forced to transform into a lich. Now that I have the means, I must help him become human again!”

Hearing Donald and Sera’s words, Chikofield’s soul flame flickered, clearly filled with emotion.

“I once helped an arcane mage under me undergo rebirth. There’s a complete set of rebirth equipment in this large laboratory. The spell for lich rebirth is also recorded in the library of the Ghost Tower in the main tower on the north side. However, the success rate of this spell depends on whether the body created is suitable for the reborn person’s soul fluctuations. It’s best to obtain a specimen from a descendant of the reborn person’s bloodline to cultivate a suitable body; otherwise, it’s just a matter of luck!”

“Still, each reborn person usually has about three attempts, so there’s a good chance of success. If all three attempts fail, it’s best not to try again, because a person’s soul essence is limited. Even an immortal lich, if it consumes too much of its soul essence, will either become a mindless puppet or have its soul dissipate!”
