The "Black Tower" that Changli mentioned was another character whom Lu Jingming had painstakingly summoned into this world after years of painstakingly accumulating real power bit by bit.
Like Jingliu, Black Tower also originated from Honkai: Star Rail. She was the 83rd member of the Genius Club, an Intelligence Envoy, and a genius of cosmic caliber.
Previously, with the dedicated assistance of Jingliu and Changli, Haiyuan City had gradually restored its basic order from the chaos and turmoil.
Those occasional sea soul beasts that ventured ashore looking for trouble were often repelled in no time by Jingliu's overwhelming strength, sometimes not even lasting a single round in battle.
However, Lu Jingming understood very clearly that merely restoring peace to the city was far from enough. To truly prosper and develop, Haiyuan City needed far greater efforts and a new path forward.
After learning that this world was currently in the peak era of the peerless Tang Sect on Douluo Continent, Lu Jingming keenly focused his attention on soul devices.
He knew very well that in this unique Tang Sect era, soul devices had become the key driving force behind the world's progress, entering a golden age of rapid development.
Their meteoric rise was already posing a tangible threat to the originally supreme and dominant profession of soul masters.
The neighboring Sun Moon Empire, by heavily investing in and researching soul device technology, had grown increasingly powerful.
As a traveler from another world, Lu Jingming was keenly aware that it wouldn't be long before the Sun Moon Empire, leveraging their advanced soul device technology, would stir up a storm across Douluo Continent and crush all opposition with overwhelming might.
If not for some godly king in the original story breaking rules to interfere with the lower world's progress, the Sun Moon Empire would likely have easily swept across the entire continent, achieving their ambition to unify the Douluo star.
Seeing through all this, Lu Jingming deeply understood the crucial importance of soul devices for Haiyuan City's future development.
So he made up his mind, enduring years of frugality and hardship to save up enough real power.
His hard work finally paid off—he managed to gather enough real power to manifest Black Tower in physical form. However, even after arriving in this world, Black Tower was in a severely weakened state.
Yet Lu Jingming didn't mind this at all, because what he valued most was not her combat strength but her unparalleled wisdom and powerful inventive genius.
In Lu Jingming's blueprint, Black Tower's intelligence and creativity were indispensable—even more important than Jingliu and Changli.
Although summoned into Douluo Continent, these characters were not at their peak strength and had lost many of their original world's formidable abilities.
But arriving in this new universe, they had also gained their own martial souls and soul skills.
For them, obtaining martial souls and soul skills might be seen as a limitation to some extent, since it differed from their once unfettered powers.
However, from another perspective, this also opened a new cultivation path in this brand-new world.
With their extraordinary talents, given time, restoring their original powers was only a matter of days—perhaps even surpassing their former heights.
"Black Tower's not here. She's definitely hiding in her lab again!" Lu Jingming glanced around but saw no sign of her, already knowing this genius obsessed with research was once again immersed in exploring the unknown.
After all, for Black Tower, a fierce thirst for knowledge was an innate trait of a true genius. Everything in this new world was fresh and alluring to her.
Though she would quickly discard any principle she fully understood and move on, the byproducts of her research greatly benefited Haiyuan City.
In less than a year, Black Tower had thoroughly studied soul masters, soul beasts, and soul devices with her astonishing intellect.
Truly deserving of her reputation as a cosmic-level genius, if it weren't for the vast differences between universes, with Black Tower's brilliance, she might have surpassed all soul masters on this world in just a month and propelled soul device technology to unprecedented heights.
Lu Jingming quietly sold some of the "defective" soul devices that Black Tower had discarded, easily earning over a billion gold spirit coins.
It's worth noting that these discarded items, deemed worthless by Black Tower, were considered masterpieces by the soul masters of the Xingluo Empire—more exquisite even than those crafted by the prestigious Mingde Hall of the Sun Moon Empire.
In less than a year, the name of Lady Black Tower had spread widely throughout the soul master circles of the Xingluo Empire.
Unfortunately, the traditional soul masters of the Xingluo Empire still held a deep-seated aversion toward soul devices and soul masters, which prevented Black Tower's reputation from truly sweeping across the entire empire despite her remarkable talents and achievements.
However, Lu Jingming actually thought this was for the best. After all, Haiyuan City was still in its early stages of development, and keeping a low profile was more conducive to steady progress.
To promote the city's growth, Lu Jingming spared no effort—even willing to sacrifice himself by volunteering as Black Tower's experimental subject as she studied the Real Authority. All this was to exchange for her inventions of practical everyday soul devices that could improve Haiyuan City's environment and technology.
Of course, Lu Jingming could have forced Black Tower to conduct her research, but he never truly wanted to.
In his eyes, these summoned companions were not mere tools; they were the closest and most trusted family he had in this strange new world.
Perhaps it was Lu Jingming's sincere attitude that moved Black Tower to wholeheartedly devote herself to Haiyuan City's development—undoubtedly relieving much of the heavy burden from Changli, who carried the weight of management, and sparing many troubles.
Although the changes in Haiyuan City were not yet significant due to the short time that had passed, Lu Jingming firmly believed it would not be long before the city would be completely transformed, evolving into the most advanced city in the entire Xingluo Empire, with hopes to even surpass Mingdu—the capital of the Sun Moon Empire and the current largest city on Douluo Continent.
After all, Black Tower had been in this world for less than a year, and most of that time was spent unraveling the world's fundamental rules and acclimating to the new material information. Even so, she had already attained the rank of a level nine soul master.
Given time, the results she could achieve would undoubtedly be even more astonishing.
At that moment, Lu Jingming stepped to the center of the awakening chamber and stood steadily right in the middle of the six-pointed star formation.
His expression calm, he looked toward Jingliu and said with steady resolve, "Teacher, I'm ready."
