The black longsword slashed across the last Honkai Zombie's body. After breaking through the black mist, it suddenly lost its force and fell towards the ground, blade tilted.
Just as the black sword was about to hit the ground, a silver spear suddenly jutted out, clanging against the floor and stopping the black sword's descent.
Kneeling on the floor, propped up by the White Flower, Ming Yu couldn't help but gasp for breath.
Nearly three hours of training had pushed his body to its limit. Both his stamina and Honkai Energy had bottomed out.
Due to the existence of Honkai Energy, a Valkyrie's physical fitness is far superior to that of an ordinary human. And when this energy is completely depleted, the weakness it brings is far greater than ordinary physical exhaustion.
Ming Yu was currently in such a state. Coupled with the depletion of his physical strength, even breathing felt laborious, as if his entire lungs were about to explode.
Given Ming Yu's physical condition, being able to last for three hours was already beyond his own expectations.
After all, not everyone's surname is Kaslana, with infinite stamina and monstrous strength as a bonus.
In his memory, a certain Paramecium had never lost a battle of attrition, even nearly taking down a Herrscher who claimed to have infinite Honkai Energy. That stamina... it's like she's made of pure grit!
The physical exhaustion made Ming Yu just want to lie down and not care about anything. But he knew in his heart that now was far from the time to relax.
Forcing himself to muster his spirits, Ming Yu fully circulated the Sword Heart's mind-method, extracting every trace of Honkai Energy from his surroundings and the depths of his body, and injecting it into the White Flower.
Due to the decrease in the amount of Honkai Energy, Ming Yu's perception of each wisp of Honkai Energy became clearer, and he could more acutely feel the miraculous changes happening within the White Flower.
The originally violent and untamable Honkai Energy, after being filtered and transformed by the White Flower, became a gentle and life-filled unique energy.
And when this energy flowed through his body, it not only quickly repaired the injuries from training but also had a good effect on the hidden injuries caused by the Black Abyss before.
He had a faint feeling that to heal the hidden injuries left by the Black Abyss, he might not need Abyss Flower's Zeroth Power. He might just need to hold the White Flower for a certain period of time.
Although the loss of life force caused by the Black Abyss sounded terrifying, it had actually just left a corrosive mark of the Black Abyss in his body. For the White Flower, which came from the same source, it wasn't too serious of a problem.
But the key was that he only had less than three days to hold this Divine Key. Therefore, the Zeroth Power was still his only choice!
Standing up, Ming Yu re-combined the Black Abyss and the White Flower into one. The silver spear quickly enveloped the black longsword, transforming into an exquisite silver lance.
Studying this Divine Key, Ming Yu couldn't help but fall into deep thought.
Although he had fought non-stop for three hours with Abyss Flower and his understanding of this Divine Key was far greater than before, it was precisely because of this that he understood how difficult it was to master the Zeroth Power in less than three days.
As for the first Welt mastering Star of Eden in less than half a day and even using its Zeroth Power to create an artificial black hole in the middle of a battle, Ming Yu could only say that the First Herrscher was awesome.
Could he really think of himself as Welt? Herrschers and humans are not the same species at all!
To achieve that step, not only did he need to have an extremely high level of mastery over Abyss Flower, but he also needed a huge amount of stamina and Honkai Energy to sustain the release of the Zeroth Power.
Although most of the Honkai Energy supporting this move came from the Herrscher Core within the Divine Key, it still required a large amount of the user's Honkai Energy to trigger it. And this huge Honkai Energy requirement alone was enough to disqualify the vast majority of people.
Simply put, his mana bar wasn't big enough to cast this ultimate.
Is asking Fu Hua for help really the only way?
Thinking of this, he firmly shook his head. Asking is impossible, not in this lifetime. Not to mention whether Fu Hua would be willing, he had his own pride to consider.
With this in mind, Ming Yu could only turn to the golden finger that had always been with him.
Earlier in the Principal's office, the performance of this system, which was usually hidden, had been very unreasonable. It had actually intervened to stop Abyss Flower's rampage, and even directly made this Divine Key submit.
Soulium can sense the user's intentions, and the user can naturally influence the Divine Key forged from Soulium.
And Abyss Flower, which had always been wielded by Schicksal's strongest Valkyrie, only respected the strong.
But Ming Yu clearly did not belong in the ranks of the strong. Even if he had gotten along well with the data-body of the Black Abyss, Abyss Flower would not acknowledge him as its user.
The one that truly made Abyss Flower submit was not him, but another existence.
If Theresa knew enough about Abyss Flower, she might have guessed that it was the work of the 12th Divine Key.
But Ming Yu, the person involved, knew clearly that because he was afraid that dual Divine Keys would cause an extra burden on his body, he hadn't brought Jizo Mitama with him at all.
With a bit of apprehension, Ming Yu cautiously asked, "System Bro, what are your thoughts on Abyss Flower's Zeroth Power?"
Although he was unwilling to admit it, Ming Yu's achievements today were indeed inseparable from this system. Whether it was the initial physical enhancement or the later assistance in cultivation, it had helped him a lot.
If the system harbored any ill will towards him, Ming Yu would be completely unable to resist an existence of this level, without even a shred of ability to fight back.
But fortunately, apart from today's unexpected action, the system had always been very low-key, not showing off at all, and had even tried its best to reduce its presence, making him almost forget many times that he had a cheat.
Faced with Ming Yu's question, the system did not answer, as if it hadn't heard him at all.
Uh...
The usually low-key system was suddenly ignoring him. Ming Yu's heart immediately felt a little panicked, but he didn't dare to rush it, and even put on an awkward yet polite smile.
Fortunately, Theresa had already left; otherwise, she would definitely have thought that Ming Yu had gone crazy from practicing with the Divine Key.
After all, the Principal was busy with a myriad of affairs and had no reason to waste time with a mere student. Therefore, Theresa had just left a few robots to monitor him briefly before leaving.
Although there were certainly more hidden protective measures, they were just to prevent Ming Yu from doing anything out of line. There was no need to hold a gatling gun to his neck.
After a not-so-short silence, a glowing virtual image of Jizo Mitama appeared in Ming Yu's mind.
Looking at the glowing sword image in his mind, and then at the nearly halved Honkai Energy Points on his panel, Ming Yu's feelings were incredibly complex.
Although the system had solved his problem once again, why didn't he feel happy at all?
Taking one last look at the Abyss Flower left in the training ground, Ming Yu made up his mind never to casually ask the system questions again, and walked towards the exit of the training ground.
