Summoned from another world, the hero is Ultraman Zeta.

The sun was shining brightly, the air was fresh, and a warm breeze blew across the river, lapping against the banks with a tinkling sound. It was the afternoon, a time that should have been quiet, but people were gathered together, each with a troubled expression.

"What's going on? Another ship has been dismantled? This is the third time this week! Can't we just live in peace?!"

"What should I do? I need to catch the boat this afternoon. Will the boat still be able to leave? Why hasn't anyone notified me yet?"

"Is no one hurt? Is no one hurt?"

The ship, towed into the harbor, drew everyone's attention. The teeth marks and claw marks on the ship were shocking to many. The rescue team cleared a path through the crowd and took the crew members, covered in mud and blood, to the hospital for timely treatment.

"What on earth is going on? Did a monster attack this place on its own initiative?"

"No, Haruki, it's not that the monster attacked this place, but that we prepared to attack the monster."

Haruki was quite puzzled by the scene before him. He found it hard to believe that a large-scale conflict between monsters and humans could occur in such an orderly place. The captain sympathized with what was happening and took the opportunity to tell Haruki and the others about what was going on.

"Ahead, a group of monstrous fish has suddenly appeared and taken over a main road, indiscriminately attacking passing ships and posing a serious threat to everyone's property and safety. The Mage Guild is trying to find a way to deal with the monsters, but this process always comes at a price."

After all the crew members were taken away, the members of the Mage Guild sealed off the attacked ship and began to study the monster traces left on it. A strange fish head was lifted up and held in someone's hand. It was not large, but a blue liquid kept flowing out of the corner of its mouth.

"What is that? It's disgusting..." Sean felt uncomfortable after just one glance. He even found it hard to associate that thing with a living organism.

Haruki didn't feel much aversion when he saw the fish head, because he had a colleague on Earth who liked to study things like monster organizations all day long.

She spent all her time looking at the monster's liver and anatomical diagrams. After spending so much time with her, even ghost stories no longer seemed eerie to Haruki. Compared to the monster, Haruki was more concerned about the crew's injuries.

On the contrary, Ah Jiu's eyes widened when she saw the fish head. She immediately summoned the legendary magic book and began to read it. She remembered that kind of monster. "'Fish Ding', right? That's the name of that monster."

"Oh, you've even studied monsters, little girl?" The captain was somewhat surprised. This seemingly naive girl actually knew a lot about monsters. The captain had originally thought she was the type who was proficient in magic.

"Not really, I just used to really enjoy reading 'The Monster Encyclopedia' and was somewhat interested in monsters."

"In that case, you'll definitely be more interested in what comes next."

Waves rippled across the water, and the wind began to pick up. This would have been the perfect time for ships to speed up, but few vessels were currently sailing out of the harbor. The few that were there were heading south, eager to get away from this place tormented by the fish-headed monster as quickly as possible.

Stepping onto the deck and feeling the ripples on the water, Haruki and the others followed the captain into a houseboat. Upon entering, they saw numerous research reports on the Fish-Ding Monster, which were posted on the walls and placed on the tables everywhere.

"The research results of the Mage Guild are all here. Don't worry, I obtained them through legitimate channels. However, I do have my own selfish reasons for collecting these." The captain let the young people tour the place without any hesitation. After a quick look at the research, Ajiu confirmed that it was the work of the guild.

"My original plan was to research some methods to deal with those fish monsters and then sell them to the guild to make a small profit. Unfortunately, I am a complete novice when it comes to research. I have all the materials and tools, but I just haven't achieved anything. I was even planning to give up here, but I think this research might be of some help to you."

As the captain explained the origin of the place, he helped the young people organize their data. The research on the characteristics and abilities of the fish monster was only preliminary, but it was better than nothing.

"The monster fish are characterized by their collective behavior and strong territorial instincts. They will launch violent attacks on anything that enters their territory. They sound like very ferocious monsters. Getting entangled with them is obviously not a good thing. Has anyone considered taking a detour?"

"Of course I've thought about it, but taking a detour would mean going around mountains and rivers, more than doubling the distance compared to the original route. There are also potential dangers during the journey, and pricing the tickets would be a real problem. Neither the crew nor the passengers want to be taken advantage of."

After reviewing the research, Yaohui raised his questions, and the captain explained them very politely, while also wryly recounting the frustrating things about the place in order to cheer himself up.

"Have you considered using other monsters to drive away those fish monsters? There are also earth spirits here, right?"

"Yes, there are, but most of those fish monsters hide in the water. It's obviously impractical to have earth-type earth users attack them. If we use cannons, we might destroy the waterway as well. No earth user would dare to take the risk of destroying the main waterway."

After saying that, the captain opened the window so that Sean, who had just asked the question, could see the two Earth Guardians in the distance. All they could do was protect the port, which was the most reliable and lowest-risk way to gain faith.

"Captain, are you so sure we can help you solve the fish monster problem? Or do you know something that others don't?" Ajiu put down the documents in her hand, turned to look at the captain sitting next to her, and became even more curious about the captain's identity.

"Yongyi Pure Crystal, Light Magic Spirit Stone. I haven't seen them before, but I'm sure I've pronounced the names correctly. I don't have much strength, but fortunately, I'm well-informed and always have a good eye for people."

The captain's words made Yaohui and Sean notice the items they were wearing. In this magic-dominated society, it was not unusual for everyone to carry crystal and mineral products when they went out. There were ornaments with even more unique designs than the Courage Crystal and the Light Magic Stone everywhere. However, the captain was the first person to be able to tell the difference between the Courage Crystal and the Light Magic Stone just by looking at them.

"Well then, it's a pleasure to meet you two brave warriors."

"Just say what you want to say, Captain. I think we should have the same goal now." Yao Hui suddenly became interested in the captain in front of him, wanting to know what his plans were.

"The port needs someone to get rid of those fish-headed monsters, and you have that power. I'm a businessman, and of course I'll seize any opportunity to create wealth."

However, I also understand that wealth needs to be shared, and for you right now, information is the best wealth. After things are done, I can tell you the whereabouts of the next Light Magic Stone.”

The captain's words resonated deeply with Yao Hui and the others. The information, though seemingly intangible, was as precious as gold, and even more important to them as they raced against time.

Last time, the disappearance of the Light Magic Stone prevented us from finding our partner hero in the end. This time, Ajiu knows how to make the Light Magic Stone resonate. If we can get the Light Magic Stone as soon as possible, we can find our next partner hero even faster.
