Maca wouldn't have agreed to Delphi's astonishing request - how could Maca risk the people around her when she knew that the agents would cause great pain and even life-threatening risks to the person taking them.

Even if he really wanted to use it for Delphi, then he would only choose to use the safe and effective finished potion directly after the research was successful.

But...... All right! It's not like Maca can't understand Delphi's feelings.

When a once powerful witch suddenly loses the ability to use magic, the feeling of extreme insecurity must be quite terrifying. In addition, Delphi has always wanted to help Maca, the "father", but with the current situation, it seems that it is not easy not to cause trouble for the other party.

Between the various feelings of disparity between the front and back, this confident girl, who has always been very assertive, must have never been able to settle down in her heart.

Yes, I am afraid that this is a fundamental problem that cannot be completely changed even by Maca's comfort and persuasion.

"Delphi, don't overthink it." Maca paused, stood up and walked up to her, reached out and patted her bag lightly, "If you become as unsettled as Hermione all day, then things like this will happen—"

As he spoke, he suddenly pointed to the crucible next to him, and then smiled slightly:

“…… I guess I'll have to hide in the corner by myself to worry and have a headache! ”

"Daddy."

Although Maca's words were more like a joke, Delphi understood that it might not be a joke when she saw the faint regret in the depths of his eyes.

If Delphi really continued like this, out of the sake of protecting her heart, Maca would probably no longer let her participate in such an event that would have a negative impact on people.

"Daddy, I-"

"All right, Delphi," Marca interrupted, still smiling, "don't worry, when this research is really successful, I'll keep a copy for you!" Until then, in fact, having Muggles use magic wasn't necessarily the only option to 'get to the root of the problem'. ”

Before the words fell, Maca suddenly stretched out her hand to her waist and groped carefully for a while. Then Delphi saw him gradually pull out of the bag a wooden staff carved with many symbols and lines, and a jewel on the top.

"It's a little long, and a little heavy, but it can be used—" Maca carried the staff and shook it in front of Delphi's eyes, "I showed it to Dumbledore at the beginning, and then I improved it a few more times - attached it with gems that could store active magic, but I didn't have much time to think about it afterwards." ”

With that, he shook his finger to the other end of the preparation room.

The next moment, I saw an ice edge suddenly sweep across the room, slamming into the wall and turning into pieces. A small hole appeared in the wall, as well as a slight crack.

"It's a little bit less powerful," Maca shrugged her shoulders when she saw this, "but the point is that you don't need to use the user's magic to cast magic. Well, if you add something to it......"

As she said this, Maca tapped her fingers at the gem at the top of the staff. With a flash of light, Maca lowered her hand and handed the staff to Delphi.

"Try it!"

To be honest, this crude-looking staff is not very pretty, and it is quite inconvenient to carry and use. However, if you want to reduce its size any further, it will be difficult to maintain its special functions.

Delphi took the staff and looked left and right curiously, before learning what Maca had just done and tentatively waved his finger.

In an instant, the cooling rune was fleeting at the top of the staff, and then a white beam of light shot forward with a "boom".

It can be seen that although the regular beam of light is short and thin, its power is completely incomparable to that of the previous icicle.

"Click-"

The walls had been frozen and cracked by extreme low temperatures, leaving a trail of frost on the walls, and it was not hard to imagine what it would have been like if it had been a human being.

"Oh yes, the amount of magic that can be stored in that gem is very limited," Seeing Delphi flute for a moment, he couldn't help but subconsciously wave it again, and Maca said busily, "If it was just the ice pick magic from before, it could have been used many times, but a rule magic like this that consumes a lot of money can only be a one-time thing." ”

Seeing this, Maca reached over and gently put it on the jewel of the staff, infusing it with new magic. When the gem erupted with a faint burst of blue light, Maca signaled:

"Remember to take it with you at all times in the future, don't dislike it, it's ugly, it's ugly, at least you can have more hope of getting out of danger in a temporary situation...... Oh, giving you this doesn't mean I'm supporting you to do something dangerous, just to defend yourself, okay? ”

Delphi was of course very happy to receive a gift from her father. After a moment's pause, she seemed to remember to express her gratitude to Maca.

However, Maca didn't care, and after saying what he had just said, he turned his head to look at the crucible, and the gurgling and boiling began to get quieter.

"Oh, this pot is almost ready."

As soon as she finished speaking, Maca nodded at her, and then walked towards the crucible. As he walked, he also said with a little regret:

"Speaking of which...... It took a lot of time to carve this long staff, and it was difficult to make it in batches. If you want to be able to withstand the rule runes, you naturally need a stable enough formation to assist...... Well, there are too many questions. Otherwise, where am I going to spend here dwelling on these potions that go against my principles? ”

Delphi wanted to say something more, but she watched from behind her as Maca got busy again, and what she wanted to say was swallowed back into her stomach.

Oh, yes! Father is already exhausted...... What is she doing here? Isn't this just going to add to my father's heart?

"Dad, thank you for the gift...... So be it! I went out first...... Oh, I'll try to look into it again by the way. ”

"Really?"

Maca turned around with a stirring stick and nodded at Delphi again.

"Good! But be careful - you know the power of the cooldown rules, so don't be careless and hurt yourself. ”

"Hmm."

Delphi looked at him and answered softly.

"Oh, yes...... Miss Granger and they might be here tonight...... After we went to the Queen's manor. ”
