It's no wonder that Kirito loses his mind, you know, Ace Wallenstein is known to have a beauty that is not inferior to the goddesses, and her appearance naturally has nothing to say.

Although Asuna is also a little beauty, she is two years younger than Ace, don't underestimate these two years, girls develop much faster than boys, so in front of fifteen-year-old Asuna, in front of Ace, she is a little girl who has not grown up yet, at least, her mind is not as broad as her family.

Feeling the sharp pain under his feet, Kirito grinned, and smiled apologetically to his girlfriend, as for his sister, does it matter if his sister has a girlfriend?

"I'm the weakest of them, do you want to practice with me?" Naoba pulled out his sword and looked at Ace.

She didn't ask her brother for money because she was strong by nature, so her slashing sword was just a projection treasure, but it was already strong compared to ordinary weapons.

"No, I just want to know how I can be as strong as you."

It's not so much that Ace is a battle maniac, but that she's an upgrade freak who always wants to get stronger in a different way, but after reaching level five, she hits a bottleneck, and no matter how hard she tries, she can't improve.

Naoba's face changed instantly, and he remembered the fear of being dominated by the original intestines, and he felt like throwing up.

"I'm sorry, but my friend is a bit direct." Finn Tim said apologetically, rashly asking how people can become stronger, isn't this provoking people? Even if people know how to get stronger, why should they tell you?

"That's ......"

Naoba actually just remembered the strengthening methods of those neuropathies, and her face became a little ugly, but when she thought about it, she seemed to have found a business opportunity!

In the world of "Pitch Black Bullet", the original intestinal virus serum is no longer a rare product, and a person will inject a branch, after all, in this world where you will be assimilated by the original intestinal virus if you are not careful, if you don't inject it, it is no different from looking for death.

But when the injection frenzy passed, the enterovirus serum began to become a bit of a chicken rib, because everyone had fortified it, and it was useless to inject again.

But what if the booster is sold to these people?

Although the original enterovirus serum in the world of "Pitch Black Bullet" is a castrated version, it can also greatly increase people's self-healing power, which is a permanent reinforcement, just ask normal people who don't want it.

"If you want to know what I mean, we can talk." Naoba stepped forward and said to Kirito: "I have something to do, you guys go first." ”

But before that, we have to test whether this thing has any effect on the creatures of this world.

Kirito: ???

We came here to take you, and you came here and threw us backhanded?

Asuna was a little pleased when she heard this: "In this way, then Kirito and I won't bother you." ”

After that, she pulled Kirito out, without this big light bulb, and then sent the two small light bulbs back to Hongxing Kindergarten to go to school, and she could live a happy two-person world with Kirito.

After the four of them left, Naoba took out a booster and explained: "This thing can greatly strengthen the physical fitness, and even allow you to have a super self-healing ability." ”

Because she wanted to be strong, she had no money and could only buy the booster produced by Sima Heavy Industries, compared to the intestinal virus serum enhancement that required a thousand Qi Luck coins at a time, this kind of thing only needed to use the gold metal rewarded by daily tasks to be exchanged at Sima Heavy Industries.

The most important thing is that if you accidentally die, you can get stronger with another injection, which perfectly eliminates the Qi Luck Coin needed to resurrect the original intestinal virus-strengthened body.

Therefore, the thrifty little sister Naoye still has a lot of reinforcing agents in her backpack.

"Isn't this just a reply prop, what's the big deal?" The guy who was dressed up like Erha, ah no, it was the snow wolf, and he came out to mock mercilessly.

"This thing works forever." Naoba explained.

Valid forever!

Hearing this, the people of the Loki clan immediately looked at the enhancer.

Compared to the Elixir of the Mihe family, this so-called enhancer looks larger, and it is not a transparent glass bottle, but a white handle.

Finn looked at Riveria Leos Alver, who took the booster, and a green cloud appeared in her hand, covering the booster, and nodded to the crowd.

She is an elven royal family and the strongest magister in Eulari, and although she is not a pharmacist, she can also distinguish between good and bad potions.

"Let's take it and experiment with it." Refia Veridis was a little worried, her idol was Ace, and she was naturally more wary of this potion of unknown origin.

Naoba snatched the reinforcer a little impatiently, stretched out his white arm, and pricked himself directly.

The syringe runs autonomously and pushes the enterovirus serum inside the straight leaf arm.

"Look, it's fine."

After that, he took out another booster and asked, "Do you want it or not?" ”

"Is that how it works?"

As a result, Loki's dependents looked at Naoye's arm curiously, looking at the wound that healed quickly, and were amazed, in Olalie, the potions were taken directly orally, or applied to the body, but this kind of direct injection into the body was useless at all.

"Well, how much do you have on you, and what does it cost?"

Although Naoba came to demonstrate it himself, Finn would not believe it on the spot, so he decided to follow Refia's advice and buy a batch back and test it before using it.

Naoba's eyes rolled, this business opportunity has not yet been discovered, but players are not stupid, sooner or later they will think of this business, so she must be the first to seize the market, and then earn enough Wallis, and then buy magic stones, and then exchange them for luck coins.

Hmph, when she has countless Qi Luck Coins, she will be able to teach Asuna to be a man, and her brother will also understand that in this world, only Qi Luck Coin counts.

"One hundred thousand Wallis is a booster, and I have ten here."

After living in Olari for a few days, Naoba also generally knows the price of Olarie, which is basically similar to that in Japan, and it costs about three or four hundred yen for a meal.

"Okay, we bought it."

Paying the money with one hand and delivering the goods with the other, although Loki is unreliable, her family still treats people kindly, and there is no scene of killing people and overselling goods.

"Don't mention this to my people, or they'll be angry."

"No problem!"

Finn smiled knowingly, showing understanding, making extra money, not chilling.

That's what Naoba wants, this business opportunity is hidden for a day, and he can earn an extra day, and when he becomes stronger, his brother won't treat him as a child.

"Isn't that right?" Simple Ace felt that it was very bad to do this.

Bert Rocca rolled his eyes and said disdainfully, "It's their internal business, what do we care." ”

Ace stopped speaking at this time, and her originally slightly three-nothing expression became very expectant, and she eagerly looked at the enhancer, with this thing, she should be able to break the bottleneck of level 5, right?

And here, Naoba is proud of his business acumen, and on the other side, holding hands with Asuna, walking back while walking, Kirito, who wants to send back two small light bulbs, finds another 'self'......
