"...I can grow stronger?"
Mai asked dumbfoundedly, as she had never expected those words from Suzuki.
After all, if she had a talent, then would he keep silent about it?
"If you know how to make me stronger, why don't you say anything?!"
"....."
Suzuki was speechless and just told the cruel fact, "It's because I have never thought you would be so uncreative."
"....." Mai.
Meanwhile, Maki, who had been silent, suddenly laughed so hard. "Hahaha..."
"SHUT UP, MAKI!"
Mai wanted to beat the shit out of Maki, but when she thought about how durable Maki's body was, she decided not to punch her. Instead, she looked at Suzuki and asked, "Tell me!"
"Hmm..."
However, Suzuki didn't answer her; she just looked away.
"....." Mai.
"Is that how you ask a request?"
Yes, Suzuki knew that he was petty, but he wanted to teach Mai an etiquette that there should be a method for one to ask for a request—
Smooch!
The sudden, soft, warm feeling on his cheek stunned him.
"Onii-chan, teach me, okay~?"
Mai held his arm while acting the cutest creature ever, as she looked at him with moist, puppy eyes, as if she was about to cry if he didn't teach her.
"...."
Suzuki wanted to say something, but in the end, he nodded helplessly. "Okay."
"Easy~!"
"..."
Suzuki wanted to smack Mai's bottom, but in the end—
Smooch!
"....." Suzuki and Mai.
"Can you teach her, please?"
Maki's face was as stoic as ever, calm, yet the crimson colors on her cheeks showed that she wasn't calm.
Still, while Suzuki didn't get angry as he got another kiss on the cheek, Mai roared, "Why did you kiss him?!"
"Is that not okay? Didn't you do the same thing?"
"Because it's me! I am the only one who is allowed to do it!"
"Then, I can do it, too."
"GO BACK TO TOKYO, YOU BITCH!"
"No, I won't."
"I will shoot you!"
"Go ahead. Your bullet won't do anything to me."
"....."
Mai was crying and clung to Suzuki. "Onii-chan, teach me to grow stronger as soon as possible so that I can beat the shit out of Maki!"
"Okay, okay. Stop fighting, you two."
Suzuki sighed helplessly, thinking that he might be taking care of children somehow.
Still, inwardly, he was glad that they could be like this, especially when they lived so oppressed, as if it was better for them to die in the past, but now?
It was clear that they could smile and look forward to the future, which made him glad that he had learned the knowledge and worked hard for everything.
"Okay, let's—"
Suzuki was about to talk about how to teach Mai to grow stronger, but his other arm was clung to by Maki, who looked away and didn't say anything.
"Why did you hug him?!"
"It doesn't matter, right? You also hug him."
"Stop fighting! Let's not waste our time, and talk about how Mai grew stronger and used her Construction Sorcery other than making bullets."
"What else? A spike?"
"You bitch!"
"Stop!"
Suzuki quickly put the two down and wondered why they kept fighting, but this wasn't the time for them to fight, as he wanted to finish this problem as soon as possible so that he could move to the next agenda.
The thought that everything was impossible was about to be realized, and he couldn't wait for this chance; he wanted to complete it as soon as possible, knowing that the faster he finished, the better it was.
"So, let's talk about how to make Mai stronger."
"Okay." 2x
So, how can Mai grow stronger?
Yes, her Cursed Energy limit was removed, but instead of improving it, all Mai did was create more bullets for her gun.
"I know what you want to say, Mai. It is an incredibly inefficient technique, as every time you try to make something, you require a massive amount of Cursed Energy, right?"
Mai wanted to refute, but as his words fell, she could only stay in a daze and remained silent, since it seemed Suzuki understood her problem well.
Yes, her Construction Sorcery was inefficient, as it took too much of her Cursed Energy, and even if her Cursed Energy's problem had been solved by Suzuki's solution previously, all she could do was create more bullets, which made her helpless.
So, how would you like to strengthen this technique?
"In my mind, your technique isn't just a minor nuisance, where you can only make a single bullet, but it has the potential of the most terrifying Special Grade ability in this world."
"R-Really?"
"Yes." Suzuki nodded. "So, will you believe in me, Mai?"
"Yes."
There was no doubt in her voice; Mai trusted Suzuki with her life.
"First, the problem that we need to solve is your lack of imagination."
"..." Mai.
"I know that it might hurt, but the truth is that you wasted your technique to create the standard brass bullets. Instead of bullets, you should study the periodic table and material sciences."
"...what?" Maki was confused.
"S-Should I study science, too?" Mai asked with a hint of doubt.
"Yes."
Mai should learn science, and there was no doubt about it.
"If you understand material science, instead of making steel armor, you can construct carbon nanotubes or graphene. It is a fraction of the weight of steel but 200 times stronger. You can weave invisible, indestructible tripwires across the battlefield, too."
"...tripwares?"
"Something that can cut just when something or someone is walking by."
"....." 2x
Yup, his idea was dangerous, yet the two listened to him silently as they looked at the periodic table, which he drew on the whiteboard.
"If you still want to use projectiles, you should construct bullets out of osmium, the densest naturally occurring element. A single bullet from this can has the kinetic energy of a cannonball, easily shattering curses and barriers."
"...." Mai and Maki.
"Lastly, the one that you might not want to try unless you understand the science is the radioactive or toxic elements..."
"Radioactive or toxic elements..." 2x
Whether it was Mai or Maki, they were trembling since even if they didn't really know science, they knew about the word "radioactive," especially since a nuclear weapon had bombed this country, so the word "radioactive" was particularly sensitive and naturally known by many.
"Instead of shooting something with a bullet, you can just create a gram of pure polonium-210 or a cloud of fluorine gas around your enemy. With those two alone, you can become a walking bio-hazard, and anyone without a Reverse Cursed Technique is going to die."
"...." 2x
"Secondly."
"There is more?!"
"If you don't think that you can't learn the science, I have read on the record that there is a strong Jujutsu Sorcerer who mastered the Construction Sorcery better than anyone, whom she hailed as one of the strongest Jujutsu Sorcerers during her era."
"Who?"
Mai wondered who could master this troublesome technique of hers and even become the strongest.
"Yorozu."
"Yorozu?" 2x
"If you don't know her, it doesn't matter, but her technique is powerful, and she is the most efficient Construction Sorcery user in history, so do you know what she created with this technique?"
"No."
"What is it?! Tell me!"
"It's a Liquid Metal."
"Liquid Metal?" 2x
By using her Construction Sorcery, Mai should be able to create a reservoir of liquid metal that flowed around her like Gaara's sand in Naruto. Because she constructed it, she could manipulate its shape and volume at will. It can act as an automatic defense (hardening on impact) and a fluid offense, turning it into whips, spikes, or blades instantly.
"When you can create it, you don't need a gun. You are the armory."
"..." Mai.
"Third method."
"There is more?!"
"Do you want to listen or not?"
"Please..."
"The third method is the assassin hack."
"Assassin?"
"Yes, you don't need to punch your opponent; all you need is to create matter inside your opponent."
"...ha?"
"Your construction sorcery creates matter in space, and the human body has empty spaces such as lungs, stomach, and arteries, so imagine what would happen if you created matter inside those empty spaces?"
"..." 2x
"When your palm touches your opponent's chest, you activate your technique and construct a solid iron spike or a cluster of razor blades directly inside their lungs or heart. When that happens, I am sure that no cursed energy reinforcement can defend against you. You directly kill your opponent."
"....." Mai.
"Lastly, your domain expansion."
"Domain expansion..."
"But, let's talk about that later when you can master all of those techniques that I have reminded you of before. No, even without a domain space, you can still become powerful."
Suzuki stared at Mai and said, "Your cursed energy problem is solved, and there is no need for you to be fixed to be a sniper. Your construction sorcery is strong. You don't have to learn a martial art like Maki. You can sit in a lawn chair, construct a railgun, synthesize a hyper-dense tungsten rod, and delete a Special Grade Curse from three miles away, but to do that—"
"I need to learn science, right?"
"That's right." Suzuki nodded. "As long as you learn the science, you can beat the shit out of everyone easily."
"I see! I don't have to have rough hands and skin!
"....." Maki.
Mai looked at Maki with a smug face and said, "Just wait, I will grow stronger!"
"I can't wait." Maki pushed the frame of her glasses and smiled.
"Teach me, Onii-chan~!"
"....."
Suzuki rolled his eyes, then took a deep breath, and said, "Let's do it later since I plan to go back to the house now."
"Eh?" 2x
"That's right." Suzuki couldn't wait any longer. "It's time to replace the old."
