Distributing flyers is the first mandatory task for all devils operating in the human world.
As mentioned before, in the modern age, people no longer personally look up taboo materials and use magic circles to perform summoning rituals to establish contracts and cooperate with devils like they did in ancient times. Therefore, delivering flyers inscribed with simple magic circles to human hands is an essential task for contemporary devils to commence their activities.
This task is usually completed by familiars and ordinarily doesn't require the devil to do it personally. However, high-ranking devils generally have their peerage members perform basic tasks for a period to gain familiarity with grassroots work. Once they are accustomed to the work, they can formally accept commissions from those with desires using the magic circles and receive payment for fulfilling their requests.
As a novice devil, Yukinoshita Yukino naturally had to start by learning this job.
Of course, she didn't need to stand on the streets like employees from various industries, maintaining a smile in crowded places and handing out flyers to passersby. Instead, she only needed to deliver the flyers one by one to the addresses of the designated targets during the deserted late hours of the night, slipping them into mailboxes or under doors.
"I just need to deliver the flyers to their homes while others are sleeping?"
Upon learning this, Yukinoshita Yukino unconsciously sighed in relief.
For a young lady who was not skilled in interpersonal interaction to hand out flyers on the street while keeping a smile would indeed be too difficult for her.
"We have no choice; we can only act at night, unlike familiars who can work day and night without obstruction," Leon explained to Yukinoshita Yukino. "The time devils can act is only night. Daytime is the time for angels and gods. If you dare to distribute devil flyers on the street during the day, and you happen to run into someone from the Church, you'll have to pray for good fortune. They certainly won't mind sending an exorcist to take you out."
"Don't make it sound so scary!" Yukinoshita Yukino's face stiffened slightly, and she said angrily, "I don't want to die again!"
Even now, recalling the scene of being stabbed through the body by Vaddel's gun that night, Yukinoshita Yukino still felt lingering fear.
Even if others encountered dangerous situations, as long as they survived afterward, it was just an experience closest to death. But she had truly died once, and that feeling was not pleasant at all.
Therefore, Yukinoshita Yukino genuinely did not want to experience the same thing again.
"Then take this."
Leon suddenly took out a bracelet-like object and handed it to Yukinoshita Yukino.
"What is this?"
Yukinoshita Yukino took it, examining it while asking.
"A light-power detector. It can detect high concentrations of light power nearby. Once it starts sounding an alarm, it means either an angel or a fallen angel has appeared nearby, or a Church exorcist capable of using light weapons has appeared," Leon said to Yukinoshita Yukino. "Chiba City is the Church's territory after all, so it's ultimately not very convenient for devils to operate here. If you wear this, it can help you avoid a lot of risks."
This was something Leon had used when he was young, brought from the Underworld by the devil responsible for mentoring him at the time. It wasn't a very precious item, but it was practical.
"Don't you use this?"
Yukinoshita Yukino asked with surprise and confusion.
"I no longer need it." Leon smiled confidently, saying, "The people from the Church should be hiding from me now, not the other way around."
Even if they can use the angels' power of light to fight, the Church's exorcists dare not provoke a high-ranking devil casually.
No matter how many battles the opponent has experienced or how firm a warrior they are, as long as they are still human, still flesh and blood, facing a high-ranking devil requires them to act in a team to have any possibility of a successful subjugation.
Therefore, unless he encounters those legendary warriors or the top exorcists regarded as trump cards by the Church, Leon, with his current strength, could retreat calmly even if besieged.
This was based on his previous self. Now, his magic power has greatly increased, and he has advanced from two wings to six wings. His strength is immeasurably greater than before, and coupled with the suddenly awakened Zenith Tempest, he no longer pays any mind to the Church personnel stationed in Chiba Prefecture.
"Also, take this with you." Leon gave Yukinoshita Yukino another device, saying, "This is a mobile device used to detect qualified transaction targets. Simply put, it's a detector to scan where our potential clients are. You just need to distribute flyers according to the location displayed on the device."
After instructing her on everything, Leon sent Yukinoshita Yukino away.
Although Yukinoshita Yukino felt somewhat uneasy, she didn't want to be seen as weak by Leon. So, she took a deep breath, unfolded her devil wings, and flew out of the manor.
Leon watched Yukinoshita Yukino leave, then returned to the underground training room.
"Swish!"
As six devil wings unfolded behind Leon, he once again flew into the air of the training room.
He was about to begin training his ability to use his Sacred Gear.
"Fire!"
Leon gave the command, and astonishing explosive flames immediately erupted around him.
The explosion turned into a wave of fire, spreading outwards like a crimson avalanche, instantly igniting the entire underground training ground, turning it into a sea of fire.
"Water!"
Leon commanded again, and intense water vapor immediately condensed out of thin air, causing a monstrous flood to appear.
The torrent was like a deluge from the heavens, crashing down onto the ground, engulfing everything in its path, turning the sea of fire into a vast ocean, extinguishing countless flames.
"Ice!"
The next second, snowflakes fluttered, and gusts of frost fell, causing a blizzard to sweep across the entire area.
Instantly, the ocean filling the basement was frozen at a visible speed. Accompanied by grating solidification sounds, it completely transformed into a world of ice and snow.
"Thunder!"
Leon raised his hand, like a king commanding the world, astonishing aura erupting from his entire body. The basement ceiling began to vibrate, and rolling dark clouds appeared out of thin air.
Lightning flashed and thunder roared within the dark clouds. Countless wild bolts of lightning suddenly crashed down, shattering the ice on the ground and ravaging the entire training ground.
The scene was practically like the legendary doomsday compressed into this small area, immediately triggering the basement's barrier, causing the barrier to become shaky.
Before long, Leon again caused strong winds to swirl in the dark clouds, making torrents of tornadoes crash onto the ground. The ravaged and destroyed floor also turned into countless flying debris, swirling into mad sand and dust storms, their power comparable to true natural disasters.
"Is this the power of the Zenith Tempest, which ranks second even among the Longinus-class Sacred Gears, second only to the legendary Holy Spear (True Longinus)?"
Leon looked at the underground training room, which was almost reduced to ruins, and felt somewhat astonished himself.
Manipulating various attributes like earth, water, wind, and fire is not actually difficult for beings who wield supernatural power.
Leon himself could materialize these supernatural phenomena with his magic power, for example. It was just that without advanced magic manipulation techniques and a strong imagination, the power was not as strong as condensing magic power into energy beams and releasing them.
However, Leon could confidently say that even the powerful beings who specialize in manipulating elemental power would cause far less destruction than the Zenith Tempest.
What Zenith Tempest manipulates is less the attributes of earth, water, wind, and fire, and more the natural forces associated with these attributes. The essence of its power is the interference with the world and with nature.
This is evident from the fact that Zenith Tempest can dominate the sky and control the climate. Without this level of power, it would not be the second-ranked Longinus, one of the current four Longinus capable of destroying a country or even causing great impact to the world.
"Although my Zenith Tempest has just awakened, in terms of destructive power, even a Super-Class Devil probably wouldn't dare to underestimate it, right?"
Leon was excited after the shock.
"Indeed, my greatest gain from taking Yukino as my peerage member was neither the enhancement of my magic power nor the elevation of my rank, but the awakening of the Sacred Gear!"
The enhancement of his magic power and the elevation of his rank granted him the strength to be at the upper end of the high-ranking devils, but the awakening of Zenith Tempest gave him the ability to challenge those stronger than himself across ranks!
Leon made an immediate judgment.
"As long as I can skillfully use Zenith Tempest, my power will definitely be able to threaten Super-Class Devils!"
This is merely the result achieved by skillfully utilizing the Sacred Gear.
A Sacred Gear is a power with infinite possibilities. It constantly changes and evolves, feeding on the wielder's thoughts, thereby becoming stronger and stronger.
The strength of a Sacred Gear, powered by the wielder's will, is basically determined by the strength of that will. If the wielder's will one day becomes strong enough to defy the world's current, and their spirit undergoes a drastic change, transforming their happiness, sadness, joy, distress, fear, and all other emotions into power, pushing the Sacred Gear to its limit, they will reach the ultimate domain of the Sacred Gear—the Balance Breaker.
That is a domain capable of destroying the world's balance, a power known as a taboo.
Once he reaches that domain, Leon might be able to contend with the Ultimate-Class Devils of the Underworld, instantly joining the ranks of the world's most powerful.
This is the terrifying aspect of Sacred Gears, or rather, the terrifying aspect of Longinus: the power to eliminate gods and Ultimate-Class Devils is no exaggeration.
Therefore, when Zenith Tempest awakened, Leon knew that his future reliance was no longer the power belonging to a devil, but the world's second Longinus.
"I must master the use of Zenith Tempest as quickly as possible. Only then can I glimpse the domain of Balance Breaker."
With this thought in mind, Leon continued to unleash the Sacred Gear's power, ravaging the basement and causing continuous, doomsday-like rumbling sounds.
