Hearing the alarm sound, Miyata wakes up and turns off the alarm. It's 6 a.m. He then goes to the bathroom to take care of his hygiene. Taking the uniform out of the closet, he notices that it will be quite tight.
'Can't believe Sewing Mastery will be useful right now.'
He then goes to find the sewing kit to adjust his uniform. After adjusting the uniform, he boils some water to make instant noodles. In the meantime, he takes out his phone to look for some information about games. Because he has Programming Mastery, he intends to make some indie games he remembers from Earth.
But he then realizes that he doesn't remember any indie games except for a few of them. Then his only option is to hack some companies to make some money. Even if he has mastery that suits the entertainment industry, he won't do it as he's lazy.
'The money can wait as I don't have a laptop or computer. After getting the money, what should I do? Make a game company to make my favorite games? Not bad, but I'm too lazy to manage it. Let keep the idea for now. Hack to leech some money? Good plan right now as I'm too lazy.'
Nodding to this plan, he pours the boiled water into the instant noodles. After eating breakfast, he goes to school. He doesn't like this school uniform too much as the color is too bright for his liking. Anyway, he gets on his bike and starts cycling to school. He gets to school quite early. He gets to his class he plops down on the table and starts sleeping.
When Miyata is sleeping, he hears the sound of someone calling him. Opening his eyes, he sees a teacher calling him. It's the math teacher from his memory.
"Kame-san! You shouldn't sleep in class like that! Can you solve this problem on the board?"
"EH?"
Letting out his voice, he then walks toward the board.
'Great Sage, it's your time to shine. But don't go overboard.'
After switching with Great Sage, he walks toward the board and writes the answer.
"Sensei. I'm done."
"It's correct… Kame-san, you can go back to your seat."
"Wow! How did he answer when he was sleeping?"
"He's quite handsome too."
There are some discussions in the background, but he doesn't care about it.
'Great Sage, you're the best! Now I can sleep in class without worrying about any subjects.'
{…}
Except for Literature, as Great Sage isn't good at emotion, but it can still write a decent essay. And the next lesson is Literature. Huh? He feels Déjà vu with the development.
In the Literature lesson, Great Sage completes the essay in 30 minutes. After that, he goes to sleep and waits for time to pass to submit his text. Nearing the end, when a girl with blue hair submits her essay, the teacher starts to cry.
'Oh yeah. This happens in anime and manga. No wonders I feel Déjà vu.'
It's a funny moment, now that he sees it in the first person. Well, if she was given the idea for Violet Evergarden, it would be awesome. And about 'Honkai Impact 3rd' too, we would be able to make the world cry.
'Such a waste of talent. Well, not that I care that much. And I won't be a part of this story anyway.'
And the day passes like that with nothing special happening. Miyata now backs to his house with a new laptop. He eats noodles like this morning. He then hacks a few companies and steals the amount of money that the companies won't notice him. His balance right now is 50 million yen.
At midnight, he was teleported to the Dungeon by the system. Taking out his sword, he clears the waves easily. Then he arrives at the 41st wave, the goblin and the big monster come out of the white light. He takes out the Colt Anaconda EX and aims at them.
'Great Sage, your revenge is here. Go for it. Auto Combat Mode.'
He lets Great Sage takes control of his body. But this time, it will be different. It then quickly headshot the goblin. It's overkill as it shots two bullets at its head. Likewise, it then kills the big monster like that too.
"Wow, it's so anti-climactic now. Well, there are only a few bullets left, so switch back to the sword. Oh, yeah! I forget about the defensive equipment!"
He then puts on the Holy Necklace and the Crystal Ring. After a few seconds, a white light shows up again. He rushes forward and kills the goblin, and retreats backward. He points his sword toward the big goblin.
"Let me call you big goblin. Now it's my turn to try to fight you."
Charging toward the big goblin, it swings its club sideways like yesterday. But now, his strength had increased. So he jumps up to dodge. With Parkour Mastery, he quickly lands and manages to get near the big goblin. He manages to cut one of its legs, losing balance, the big goblin falls. He then gets on its back and cuts its neck.
After 20 waves, he gets tired. Taking a break, he thinks about what skill he should take.
"Sword Mastery or Cooking Mastery. Ah… What should I choose? I'm sick of only eating noodles. I want to eat a good meal. But Sword Mastery will help me a lot in Dungeon. Good food or efficiency. Haas… Life is tough with choices."
'Wait a second. Cooking involved using a knife. So if I get Cooking Mastery, I may be able to use a sword as a knife.'
"I'm such a genius."
Then the white light shows up two big goblins walk out of it. Miyata doesn't have enough confidence to fight two big goblins simultaneously. He can only let out a bitter smile, stands up, and charge towards them.
The big goblins are standing side by side. They don't stand in one place, as they charge at Miyata. One goblin swings its club from the left, and the other one swings its club like a hammer to smash him. The club has better reach than his sword because the club is like 2.5 meters long. He manages to evade the attack by jumping backward but is affected by the shockwave.
After recovering from the shockwave, he feels it's quite impossible to kill them with only a sword.
'If only Colt Anaconda EX has unlimited ammo, I would be able to win. Or I can use Thought Acceleration and Parallel Processing from Great Sage. Unluckily, I have to activate them by using mana which I don't have.'
Afterward, the goblins smash Miyata into pieces, when he wakes up from his room. He is curious whether his soul or body teleports to the dungeon. Because he didn't feel any pain when the monster killed him. He then asks the system, but it doesn't answer his question, so he can only shut up about it.
He then buys the Cooking Mastery skill. His previous theory was correct, and now he can use the sword better. Tomorrow he will buy the Sword Mastery skill. After that, he will save 1000 points to roll in the skill gacha. Done making his plan, he goes to sleep.
