Divine Luck: SSS-Rank Battle Maid Harem

After Alzara finished the recipe for the medicine against the underworld energy poisoning, Zach got a little more free time on his hands. He would occasionally make worms with his skill for Alzara. He would occasionally train his body or with his spear. Occasionally, he would go down to the city and help out or check on things and his friends.

He got even more free time when Nessa got him to sell the rights to use the recipe to a few of the alchemists in the city.

Zach hadn't even thought of doing that. He knew that there were alchemists in the city. He just hadn't thought of them.

It also hadn't occurred to him to sell it. Why would it when he wasn't selling the medicine? They handed that out to the citizens for free.

People who wanted to thanked them with donations of money or materials. Others bought talismans and food at a higher price. Zach and the others were making more than enough money to make things go around.

However, what Zach failed to consider or failed to know to consider was the revolutionary existence of the medicine and the anti-underworld energy potion. It was understandable nothing like it existed on the open market since most people didn't know about the Underworld.

But not even the Underworld Exterminators had anything like it. Two consumables and an item extremely efficient against underworld energy were all that existed, and all three things came from Zach. The research potential alone for alchemists was tremendous.

Even beyond that, there would be a market for the medicine and the anti-underworld potion in the future. The current situation in Basilia was almost over. It wouldn't be long until practically all of the underworld energy had returned to ground and endless vomiting would be nothing but a faint memory in peoples' minds.

But the Underworld wasn't gone. Underworld energy still existed. Even if Basilia was fine, other places might not be. And by all accounts, the Underworld was picking up its activity. The value of the medicine would only rise as the Underworld launched more attacks on the surface and poisoned more people.

Not only that, the medicine Zach had crafted was also an efficient way to prevent traitors or subtle poisonings.

With the medicine, people would turn angry and bitter like Julius had done in their first year.

With the medicine, people wouldn't be able to join the Underworld.

Of course, forcing everyone to regularly take the medicine was impossible. But it was useful for expeditions, the Exterminators, and people in vulnerable or already attacked locations.

Then, there was the potion and the talismans. Zach was a little more reluctant to sell the recipes to those.

The potion because it wasn't easy to make and because it was too powerful. It might cause more trouble if it was available en masse right now. And if people learned how to make the talismans, it wouldn't take long before they figured out Zach and the others had scammed everyone.

People would find out eventually. It was inevitable.

But Zach would prefer if it happened when it was in the past and when he was far away.

Still, Nessa didn't give up. She saw a business opportunity. But she didn't just encourage Zach. She also worked to secure skilled and trustworthy alchemists who were willing to go pretty far for the sake of research and valuable potions.

After all, unlike most people, Nessa knew Zach wasn't the one making the potions, medicine, and talismans. It wasn't even like Zach had tried to keep it a secret from her or the others. She had just been the first to barge into the lab.

Nessa knew that it was Alzara who made everything. In a way, she was more reliable than Zach. Nessa could also tell that Alzara wouldn't stop making potions anytime soon, nor would she stop creating new recipes.

The anti-underworld energy and similar products had taken priority due to their situation. But what if Alzara had some time to spare? What if the Desert Witch got bored and started making interesting things?

Right now, it was nothing more than a gamble on Nessa's side. But she had a good feeling about it.

However, something else soon overturned that good feeling.

It was a slight tremor. It made rings appear in the water in the cups on nearby tables. Slightly longer weeds and straws of grass swayed slightly. A leaf or two fell from a tree next to the road.

In the sewers, a loose rock crumbled and bounced to the floor.

In the tunnel, a thin crack grew to the length of an arm in one part of the wall.

That was it.

What happened below the surface, no one noticed. Most didn't even notice what happened on the surface.

Zach did. He happened to be in the camp, talking shit with Dukiel and Violina. They also noticed. Anerias noticed. Nessa noticed. Their familiars noticed.

A few of the other students noticed. Several of the Underworld Exterminators noticed.

Many of the students were technically more powerful and useful in combat than most of the Exterminators, thanks to their familiars. But their senses and instincts weren't as sharp. They had gone through troubles of their own, but the students hadn't lived as long as the Exterminators. They hadn't experienced nearly as much.

The Exterminators had lived through enough dangerous experiences for their instincts to warn them that something bad was going to happen–had already happened.

However, there was no way to know what it could be. A vague sense of foreboding wasn't enough, especially when all it did was start dialing up their fear.

It didn't immediately click for them that it was the Underworld–that it was something below the city.

It did for Zach. It did for the others in the club. They had had enough close run-ins with the Underworlds to know. They had also only had close shaves with the Underworld. What else could it be if not them?

Zach and the others turned toward the city with grave expressions.

Whatever had caused that tremor was powerful. It took a lot to affect that much mass from that deep in the ground.

A manhole cover, twenty pieces of rubble varying in size from a pebble to a melon, and dust rocketed into the air with a bang.

By the looks of it, they would find out what had caused that tremor soon.
