Arknights' Lock of Heaven

As she demonstrated, she gripped the corner of the table with one hand and exerted a strong force!

"Ouch..."

Then I almost threw out my back...

Xia Yu, standing behind Amiya, let out a cold laugh upon seeing this.

Ha, you expect me to use it without activating it?

Upon seeing this, a big question mark appeared in Amiya's eyes.

"Doctor...are you...alright...?"

"It's alright," the doctor said, clutching his lower back and taking a deep breath.

Then he turned to look at Xia Yu.

"If you don't want our gossip to spread throughout Rhodes Island tomorrow, you know what to do!"

"No, how can you, a girl, use this to threaten people?"

Xia Yu expressed her incomprehension, "Don't you even care about your own innocence?"

Upon hearing this, the doctor let out a cold laugh.

"Go look in the mirror, look at your face. Did I suffer a loss? Am I the one who suffered a loss?"

"That doesn't exist!"

These two questions left Xia Yu speechless.

At that moment, he finally understood that the saying "boys should protect themselves when they are out and about" was not without reason.

That's a truly profound saying!

Faced with her threat, Xia Yu had no choice but to activate the spell.

There's nothing we can do; in this respect, we're the ones who really suffer.

This world... there's no justice!

As the intricate patterns on the card lit up one by one, the doctor nodded in satisfaction.

Hehehe, found a weakness.

Not a loss!

Then she held up the card and spoke excitedly to Amiya.

"Come on, Amiya, I'll show you a special skill!"

Then, with a whoosh, the entire desk was lifted up.

Amiya's eyes widened upon seeing this.

This, this, this...

I can barely speak properly anymore.

Watching the doctor not only lift it up, but also swing it up and down...

This is a solid wood desk!

Let alone the Doctor, even those elite operators known for their strength probably couldn't do it this easily.

She knew all too well how weak the doctor's body was.

"See?" Xia Yu, who was standing next to her, said softly, "Look how excited she is. I was really trying to stop her from tearing down the office!"

"You have to believe me, Amiya!"

"I will always believe in you, Mr. Xia Yu!"

Hearing this, Amiya turned her head and said solemnly, "Also, that card is..."

“That’s right, it’s my creation,” Xia Yu said with a smug smile. “I experimented on Lin Guang’s sister for a long time before I finally got it.”

“This… Originium Arts that unleash the body’s potential…” Amiya, of course, couldn’t think of magic, and instead looked at the Doctor with concern, “Doctor, with your current body, will…”

"Doctor, you should stop right now! We need to get to Dr. Kal'tsit for a checkup!"

Generally speaking, this kind of Originium Arts has some side effects, big or small.

Judging from the level of increase, the side effects must be enormous.

To be able to amplify a Doctor who was completely powerless to this extent, if she hadn't always trusted Xia Yu and knew about the other's amazing abilities, she would have immediately taken action to subdue the Doctor and rushed to Kal'tsit's side.

It's no wonder Amiya had the wrong idea; after all, that's how she was raised, and it's hard to change that overnight.

"Don't worry, it'll be fine. And even if you go to Kal'tsit, she probably won't have time," Xia Yu shrugged easily, seeing her worried look.

"This isn't the kind of Originium Arts you're thinking of; it's... some kind of more advanced technology."

Xia Yu said softly, "Everything that carries the spell is on that card, from the energy source to the spell itself. The carrier is never the human body."

"It will not affect the human body itself."

"Oh, but injuries sustained from getting used to this power and then subconsciously doing things that were still loading after unloading it don't count."

In short, it is a magic that utilizes the simplified formula that Leonardo da Vinci developed for himself, combined with the Holy Grail as a magical foundation imprinted on the world.

The technique is also very simple: enhancement.

Moreover, it is a enhancement specifically designed for the human body.

During the Fifth Shinobi World War, Medea used this enhancement technique to strengthen her Master, Souichirou Kuzuki.

The enhanced Kuzuki Souichirou was even able to fight Saber King Arthur to a standstill for a short period of time, and even suppress her.

Xia Yu used this kind of enhancement technique.

Of course, a single card can't compare to the enhancement Medea gives to her Master.

After all, the purpose of this is to mass-produce it, while Medea's enhancement is intended to be used as a weapon for the final battle.

It's obviously incomparable, but even after being weakened, it's still sufficient.

Any more? Sorry, Xia Yu is afraid Rhodes Island can't afford that price.

For any mass-produced product, cost-effectiveness must be taken into account.

He's not some heartless capitalist, is he?

It's important to know that the magic power used in spells is entirely supplied by the Holy Grail.

I spent all my own money!

Each card produced is provided to operators at cost, and of course, Rhodes Island pays for it.

This is the concept of the Xia language.

However, he wasn't entirely heartless; the card also had an overload function that could boost performance to its maximum in a short period of time.

It only lasts for three minutes, after which the card will break...

But is the strength of a Servant for three minutes, or is it the strength of a Servant of Artoria's caliber...?

That's enough to open the eyes of any enemy.

233 Kroos doesn't want to work overtime

"PhD!!!"

After receiving the card from the Doctor, feeling the powerful force that instantly filled her body, Amiya turned around and glared angrily at the Doctor.

"Why experiment with something so dangerous in the office?"

"Does Rhodes Island not have a training ground?"

"This...this, I couldn't help myself, I couldn't help myself..."

Upon hearing this, the doctor awkwardly looked away and said guiltily.

"And Mr. Xia Yu!" After reprimanding the postdoctoral fellow, Amiya turned her gaze to Xia Yu.

“You know the Doctor’s personality, so why don’t you… um…”

Amiya wanted to ask why the doctor didn't stop him, but when she remembered the scene she saw when she came in, her face turned red.

This... seems to be stopping it...

However, "How could you entrust something so important to the doctor here!"

“There’s nothing I can do,” Xia Yu said, shrugging. “I originally wanted to talk to Kal’tsit, but she told me to come see the Doctor directly.”

"I originally intended to approach the Doctor and then go to Kroos, but as you've seen, things have turned out differently."

Xia Yu meant that he would not take the blame.

Kal'tsit sent her herself.

“Um, Dr. Kal'tsit…” Amiya was also at a loss upon hearing this.

"By the way, what exactly did you talk to Kal'tsit about?" the Doctor asked curiously. "Why... couldn't she even spare the time for something so important?"

Is it important?
