Mona's temporary lecture lasted all day! During this process, Mona and Kasha's sisters were petted without rest or ate anything, and they accepted Mona's lecture as if they were in a nightmare.

At noon, Oz suggested that they take a break, but Mona refused very flatly.

"My devil, the ordinary way is to not be able to complete the maid course in a short time. We are now in a state of spiritual resonance. The longer the duration, the better the learning effect. We can complete all the courses in two days after this! If we interrupt the middle, we may not be able to complete all maid courses even if we spend the first half of the year."

"But can their bodies bear it if this continues?"

"Don't worry, Lord Demon. The SAN value dance created by Demon King Nayaratotip is not an ordinary person. Even if you don't eat, drink or sleep for three days, you'll be fine after sleeping."

Although he was still a little worried, seeing Mona saying so confidently, Oz didn't insist anymore - since he even became a demon king, what else could he not accept?

But as time goes by, Mona's teaching method becomes more and more strange.

In the morning, I was still using normal oral methods to teach. In the afternoon, Mona began to speak some strange radio words, and at night, it even turned into silent spiritual communication...

Seeing Mona's fierce teaching method, Oz once again deeply felt Mona's uniqueness - a strange body that completely violates evolution, a magical space stomach bag, an immortal body that goes against the sky, and various strange knowledge and abilities... I can only say: Is it worthy of being a god's devil?

The lecture between Mona and Kasha sisters lasted for two days.

The next afternoon, when Oz was about to go to the beach with dry food to find a mermaid, Mona finally finished teaching, and the Kasha sisters fell asleep as Mona said before.

In Kasha's room, Oz looked at the two girls lying on the bed, like sleeping beauty: "Is there really no problem with Kasha's sisters? I haven't had any rest for such a long time, will there be no sequelae?"

"Hmph! SAN value dance has obtained the authoritative certification of Lord Kami, and is the most perfect spiritual synchronization method in the multiverse!"

Oz: "...I don't know why, but I always feel that if I dance too much, I will become a brainless person. Forget it, I won't talk about this anymore. I plan to go out of the city to the beach at night to see if I can meet mermaids. Just stand by at home."

Mona: "Master Demon, what are you going to find a mermaid to do?"

Oz: "Kill mermaids and earn world-destroying points."

Mona looked at Oz strangely: "Why are you unwilling to massacre humans by any means, but you don't mind massacring goblins and fishmen?"

Oz said angrily: "It is not a pleasant thing to kill each other."

Mona: "My devil, you are the devil, not a human."

Hearing Mona's words, Oz was silent for a while, looking down at his hands: "...It would be too far-fetched to say that my body is human. But... whether it is a 'human' and whether it is a 'human' are completely different concepts. The so-called human is a kind of biological classification; while 'human' is a conceptual classification. I cannot agree with the act of killing people casually, but I don't mind killing humans who are 'non-human'."

"It's just killing someone, is it so complicated?" Mona sighed, "Sure enough, the devil without black history is just a troublesome, and killing someone will have to complain for a long time."

"I just like to think." Oz shrugged, "I won't talk about this anymore. I'll go kill mermaids and earn the world-destroying point, so you can stay at home."

"Yes~ Lord Demon."

After watching Oz leave the house, Mona touched her chin: "The mentality of the Demon King has not changed to the mentality of the Demon King at all. According to observations during this period, although the Demon King likes food, he does not overeat; although he has a good impression of women, he does not have much lust; although he likes money, he is not greedy; although he is not urged, he is not lazy; although he is often angry, he is never angry; although he is not rich, he is not jealous; although he has gained strong power, he does not become arrogant at all... Wow! None of the seven sins are involved! This kind of devil king who is pure and has no desires is the devil king!? Demon King is too restrained. It seems that it is very necessary to use girls to stimulate the devil king's desire."

Lord Demon King, follow your desires! Don’t suppress yourself anymore!

Mona was making all kinds of strange ideas at home, and although Oz knew nothing about it, his time of getting along also gave Oz a certain understanding of this white steamed bun: although Mona had some strange abilities and knowledge, and often did some extra things, its purpose was to assist the Demon King, so Oz was not worried that it would really be unfavorable to him.

Oz wore two magic guns on his waist, holding a fish basket in his left hand and a fishing rod in his right hand, walking towards the outside of the city, preparing to leave the city and find trouble for the fishman.

What? You ask me why I brought fishing rods and fish baskets? That's because fishmen all live in the water! God knows when they will get ashore. If they don't get ashore for a whole night, they can't waste their nights in vain, right? So, bringing fishing rods and fish baskets can also improve the dietary problems at home.

On a cliff that was not too high, Oz threw the fishing line into the sea, supported the fishing rod on the ground, then sat on the ground, took out a book, and slowly looked it through.

Under the moonlight, the silver waves rush against the stone walls persistently, making a rustling sound, and the slight salty sea breeze blows on the coast, making people shocked. Not far from the cliff, there is a small fishing village with brightly lit lights, and the villagers who have been busy all day are having dinner happily at their homes.

That village is a fishing village that has been harassed by fishmen recently.

According to information obtained by Oz from the Adventure Union, since the weather has begun to warm up, the fish people's actions have also become frequent, and they often appear in nearby coastal areas to steal the fishermen's tools, and even often destroy fishing boats at night, which has caused great damage to the village. Therefore, it is hoped that adventurers can kill ten fishmen and find the nests of these fishmen.

The combat power of the fishman is not higher than that of the goblins, so it is very easy to kill ten fishmans, but finding the fishman's nest is a very life-threatening task.

The fishman has a certain wisdom and gathers and lives on the coastline in the form of tribes and villages. However, near big cities like Billy, the fishman's villages are almost hidden in some dark and wet caves, or on isolated islands in the sea. If you are not lucky, the entrance to the cave may even be under the water, which is extremely difficult to find. Fortunately, Oz's purpose is not to complete the mission of the adventure union, but to obtain the world-destroying point by killing the fishman, so it is enough to wait patiently on the shore.

Oz sat on the shore, looking at the books in his hand leisurely. The slightly damp sea breeze blew across the pages, making a rustling sound.

"Standard Spells: Level 5" This is the name of the book Oz is reading. It is a standard magic textbook that mainly explains some advanced techniques for spell casting.

Just as Oz was reading a book attentively, a "ding-ding-dang" bell sound suddenly came from the top of the fishing rod. It turned out that a bell was hanging at the top of the fishing rod. When a fish dragged the fishing line, the bell would ring.

When Oz heard the bell ringing, he quickly put down the book in his hand, picked up the fishing rod, and pulled it hard!

"Hey!" The power on the fishing rod was beyond Oz's expectations. Unable to defend himself, Oz was taken forward by the fishing rod and took two steps, "Please, it's a big guy!"

Oz quickly loosened the fishing line of the fishing rod, let the creatures in the water drag the fishing line to run, and tightened the fishing line from time to time to relax the fishing line... When the force underwater was slightly slower, Oz took the opportunity to hold the fishing rod tightly with both hands and pull it hard!

"Crash!" A loud bang! An adult-sized creature jumped out of the water!

"Huh!!" When Oz saw the creature he dragged out of the water, he couldn't help but look surprised.

Her skin is fair and her green ponytails tied with two shell hair accessories, she looks like an ordinary human woman, but her lower body, which is exactly like a fish, reveals her identity!

Mermaid, also known as mermaid, is a beautiful race that lives in the deep sea.
