In the vast underground training ground, the surrounding walls and floor were covered with sci-fi style patterns, with streams of light flashing through them from time to time, as if data were flowing within.
In contrast to this sci-fi style, the training ground was filled with slender female figures dressed in strange black attire, with a faint black mist surrounding them. They skillfully wielded various melee and ranged weapons, perfectly utilizing their functions and showcasing their destructive power, leaving marks on the training ground's floor and walls.
And amidst these figures, there was one particularly conspicuous silver figure.
He skillfully weaved through this strange crowd, his body twisting and leaping, dodging the light arrows shot by archers and evading the black longswords that swung at him.
He brandished the silver spear in his left hand, blocking attacks he couldn't dodge in time, parrying countless attacks from tricky angles that were difficult to avoid.
The spear danced like a soaring silver dragon, and those attacks that could leave scratches on the alloy floor were neutralized upon it.
The black longsword in his right hand was also in constant motion, mercilessly stabbing towards those well-built ladies in black.
The blade cut through the air, and the figures it struck instantly turned into black mist, dissipating into the air with the wind.
Without a doubt, the active figure in the field was Ming Yu, who had obtained Abyss Flower.
No matter how powerful the healing abilities of this Key of Creation were, it could not escape its destiny as a weapon.
Whether it be a sword, a blade, a spear, or a cannon, for any object that exists as a weapon, its value is directly reflected in its participation in combat!
Even a weapon as exquisite as a work of art like Abyss Flower was no exception.
After all, although Abyss Flower was excessively beautiful for a weapon, it was not as fragile as a work of art.
As a Divine Key, Abyss Flower was definitely more durable and resistant to the ravages of time than ninety-nine point nine percent of the objects in the world.
No matter what Ming Yu wanted to do with this Divine Key, the first thing he had to do was to familiarize himself with it.
And for a weapon, the best and fastest way is through combat!
Although Ming Yu had not specifically practiced with long-handled weapons before, the principles of combat are universal, and the use of weapons has commonalities.
After a brief period of familiarization, he was quickly able to wield both the Black Abyss and the White Flower with proficiency, just not as expertly as with a tachi. However, it was already sufficient for ordinary combat.
But if he wanted to challenge the Zeroth Power, which could be considered the ultimate secret technique, with just this, it would be too much of a fantasy. To reach that step, arduous training was still indispensable.
Thrusting the Black Abyss into the body of the last enemy, Ming Yu leaned on the White Flower and let out a long breath.
While quickly adjusting his disordered breathing rhythm and circulating the active Honkai Energy in his body according to the method from Fu Hua's Taixu Sword Heart, Ming Yu was also doing his best to feel the state of Abyss Flower in his hands.
Perhaps due to the battle, Ming Yu could clearly feel that Abyss Flower in his hands had also become active.
Unlike its reserved state in the case, Abyss Flower felt much more lively during combat.
He could almost hear the call from the Black Abyss, a longing for slaughter and death.
Perhaps due to their different functions, the feeling the White Flower gave him was completely different from the Black Abyss. It was like a calm and quiet young lady who never actively showed her desire for battle, but just silently protected Ming Yu with her power, helping him to fight better.
It was precisely with the help of the White Flower that Ming Yu's endurance was greatly enhanced.
After Honkai Energy flowed through the White Flower, it immediately returned a gentler energy. Not only could it repair the injuries caused by the Honkai Zombies, but it could also alleviate Ming Yu's fatigue and maintain his combat readiness.
After a short rest, feeling that his condition had recovered somewhat, Ming Yu waved the White Flower at Theresa outside the training ground, signaling her to start the next round of battle.
Upon receiving Ming Yu's command, Theresa sighed helplessly. But she still complied with Ming Yu's request and began to set up the simulation targets for the next round.
This is the fifth round, right? The training has been going on for almost an hour. He didn't have this much stamina in the Stigmata Space, did he?
Is this... also the power of Abyss Flower?
Although she was grumbling in her heart, Theresa's hands didn't slow down at all.
Looking at the Honkai Zombie figures reappearing in the field, Theresa couldn't help but sigh helplessly in her heart. What a waste of a great tool!
This was her exclusive training ground, which also had the ability to capture the user's brainwaves and simulate suitable opponents from their memories, achieving a more excellent training effect.
But when Theresa proudly introduced this function to Ming Yu, the boy rejected it with a look of disdain, even saying that it was a violation of rules to obtain intelligence and insisted on using the normal mode for training. He even went so far as to bring up the agreement they had made to make his point.
Helplessly, the Principal could only turn off this extremely rare and precious Memory Battlefield training mode, which was a treasure even within Schicksal, and switch to the normal simulation training mode, forcefully turning a high-end, exclusive training ground for S-rank Valkyries into a common public training ground.
Thinking of this, Theresa felt another surge of anger and glanced resentfully at the silver figure twisting and turning in the field.
Although the simulated Honkai Zombies were getting stronger, it was clear from Ming Yu's performance that he was constantly improving, and his use of the Divine Key was becoming more and more adept. At the very least, the black mist emanating from the Black Abyss had become much thicker.
Given time, perhaps this kid could really master the Zeroth Power, Theresa couldn't help but sigh in her heart.
But she immediately shook her head. That was impossible, at least not this time.
Although Rita would be staying at the Far East Branch for three days, since the third day was the Valkyrie Rank-Up Exam, Ming Yu would only have about two days to actually interact with Abyss Flower.
Moreover, he couldn't take Abyss Flower back to his residence; he could only use it in this training ground.
After all, for the Far East Branch, Ming Yu still posed a potential threat. Since he was unwilling to hand over the 12th Divine Key to Theresa as collateral, the Principal naturally couldn't entrust Abyss Flower to him.
Even though Theresa had sided with Ming Yu on the matter of Abyss Flower, this point would not change. She would provide convenience to Ming Yu within the scope of her authority, but she would not trust him unconditionally.
For Theresa, Ming Yu was always just an option, not the only choice.
At most, Ming Yu was just a spare piece in Theresa's game.
If she could gain a combat power equivalent to an S-rank Valkyrie in the future, that would naturally be good.
If not, it wouldn't be a major issue for Theresa either. She would just need to make some other plans to compensate.
Watching the Honkai Zombies in the field decrease one by one, and the young man's movements in wielding the Divine Key become more and more fluid, Theresa licked her lips slightly, a trace of anticipation rising in her heart.
Although she knew the possibility was slim, she still murmured in a low voice, "Come on, let me see, what kind of abilities do you really have?"
