Brian knew very well that with Ms. Polaris alone, in the process of growing up in the floating city, it was difficult to support all the operations of this huge castle alone.

Even if Ms. Polaris is capable enough to support her, Brian is unwilling to let her take all the responsibilities.

He still understands the reason why eggs cannot be placed in a basket. If something happens in the middle of the journey, it will be too late to regret it.

Therefore, as the floating city gradually improves, it is very necessary to recreate several effective tower spirits to assist Ms. Polaris in jointly managing the floating city.

Brian not only cared about this matter, but even devoted countless efforts to ask Ms. Polaris to assist herself in researching the production of Taling.

With his unremitting efforts, the harvest was quite good.

Through the fusion of several legendary elemental spirits, the tower spirit called "Nine Chapters of Arithmetic" has been born in the Floating City.

The main function of the Tower Spirit’s ‘Nine Chapters Arithmetic’ is to calculate. Supported by the huge energy of the floating city, any legendary spell prohibitions and spell traps will be left uncovered under its concept scanning and ban breaking techniques and will be easily unlocked.

In addition, it also has storage knowledge, assists various defense facilities in the floating city to guide super magic, and strengthens super magic skills, so as to maximize the power of various types of mysterious locks and magic crystal pulse cannons.

In short, the newly developed Taling ‘Nine Chapters of Arithmetic’ by Brian is similar to an artificial intelligence with powerful computing power, which can assist Ms. Polaris to complete various operational analysis and attack instructions more efficiently.

The main reason why Brian didn't think of asking "Nine Chapters of Arithmetic" to help him solve the ancient black dragon treasure is that although this tower spirit has been initially completed, many details have not been improved.

If the operation is overloaded and there is something wrong with it, it will be more troublesome to recover.

This is also the main reason why Brian was the first to ask about Taling's condition after contacting Myrcella.

If this tower spirit cannot support such a huge calculation for the time being, then he can only slow down the Black Dragon treasure first, and wait until he can free up his hands, or the tower spirit can operate normally before considering it.

On the other side, in the floating city, after hearing Brian's inquiry, Myrcella raised her hand and lifted her hair hanging down on her forehead. After thinking a little, she said to him, "Basically, 'Nine Chapters of Arithmetic' has been completed. Next, it is only left to run in with the entire floating city system. This process is like carving a piece of rough jade, which requires patience and meticulousness to make it flawless."

Speaking of this, Myrcella paused slightly, and a trace of undetectable worry flashed in her eyes.

"Of course, in the process of running-in, we will inevitably encounter various problems. At that time, we need to readjust and change according to the specific situation. If we only crack some restrictions and spell traps, the ability of "Nine Chapters of Arithmetic" is more than enough, so you can rest assured."

"It's so good." Brian nodded with satisfaction when he heard Myrcella say this. After all, she is the most stable person in terms of Myrcella's efficiency in both on and under the bed.

If she said there was no problem, it was really no problem.

"Then let's start."

No more wasted time, Brian moved his mind slightly, raised his hand and cast a staff towards the outermost layer of the Black Dragon Treasure, and cast the "highest magic relief" on the outermost layer of the Black Dragon Treasure.

As the spell was cast, a dark blue aura slowly filled the thick layer of deep purple ban that suddenly appeared on the surface of the treasure cave.

The dark blue magical aura released by Brian immediately overlapped with the ban, and then the thick ban began to tremble violently, making subtle sounds similar to the collapse of gears.

In just a moment, this layer of ban that witnessed the changes of countless years. In the face of Brian's extremely exquisite magical skills, it collapsed like fragile porcelain, turning into purple lights, dissipating in the air, without traces.

At this moment, Myrcella, who was facing Brian's void, also found the right time to drive the tower spirit's Nine Chapters Arithmetic.

"The tower spirit's 'Nine Chapters Arithmetic' has been activated successfully!" With this announcement, the ancient magic tower seemed to have been given a new life.

"Concept scanning is being started..." A series of cold mechanical sounds echoed in the tower, like the gears of time slowly turning, pulling everything back to its original starting point.

The magical light of the tower spirit was like an invisible giant eye, locked on the layers of prohibitions of the Black Dragon Treasure, and began to calculate frantically.

"Concept Scan has started!" The mechanical sound rang again, immediately focusing Brian's attention on the core mage tower of Floating City.

"The target is being scanned..." With this announcement, the magical aura began to jump on the restriction, like a flexible dancer, shuttled through the complex patterns.

"Scan progress:...1%!...12%!...36%!...100%!" Every update of the progress is accompanied by a slight vibration, like a pulsation of the earth, indicating the upcoming changes.

"Scan the whole!" With this announcement, the magical aura suddenly converged and turned into a dazzling light, illuminating the entire tower.

"The number of target bans has been successfully confirmed and is being cracked through concept analysis..." The mechanical sound sounded again, and Taling began to use its powerful computing power to analyze the bans one by one.

"Cracking progress:...2%!...17%!...59%!...100%!" Every update of the progress was accompanied by a slight roar, as if the tower spirit was exerting its supreme magic power.

"Cracked!"

As a crisp ringtone rang, all the restrictions seemed to be dissolved by invisible power and turned into nothingness.

"Selecting the optimal solution..." Taling did not stop computing, but continued to use its powerful computing power to prepare for the next action.

"Selected!" With a firm announcement, Taling has found the best solution.

"Ta Ling's 'Nine Chapters of Arithmetic' has successfully activated the conceptual breakthrough technique!" With this announcement, Brian seemed to feel that the entire Black Dragon Treasure Cave surrounded by the forbidden seemed to tremble.
Chapter completed!
