A closed room in the institute.

The room was dark, and the only source of light was a bright magic lamp, which was very concentrated from above, shining on the platform in the center of the room.

Shirley is tied up as a caterpillar and lies on the platform.

Roy, Alice, Gina, and a group of researchers surrounded him.

Roy asks Alice:

"Do you know what kind of dragon she is?"

Alice shook her head.

"I've never heard of this kind of magic, and I haven't heard of a dragon that can unleash dragon magic through its voice. In the world of the brave man, there are many magical things that we can't understand. ”

"Well, that's just for us to investigate."

Roy thought of the center-symmetrical sound wave graphics that the computer had synthesized when music was playing. As Alice is singing, a 3D, ever-changing sonic magic array appears around her body. It was through this magic array that she emitted her spiritual power and magic, causing damage to the creatures around her.

"Shirley, is there really no record of this in your inheritance memory??"

Shirley shook her head and said:

"I really don't know, there are only a lot of dragon ballads in my inheritance memory, and I really don't know if these ballads are still lethal."

Shirley craned her neck and looked at the researchers around her in horror.

The researcher's terrifying gaze at the mouse made her tremble.

"Then test all the songs in your head."

Roy unties Shirley.

The group went to a closed room and set up layers of magical barriers. After that, the best cannon fodder in Demon King City was invited: Goblins.

Giving the goblins Gothic Dynasty skins, they entered the testing room with the determination to die.

Shirley began the show.

As soon as she spoke, the air around her visibly distorted, forming a three-dimensional and ever-changing magic array. The five goblins in the room seemed to have been smashed with a hammer, and their bodies stood up, and they really fell backwards, falling to the ground, foaming at the mouth, and convulsing all over.

Pull it away and change it.

"Shirley, change the song."

Shirley sang other songs.

This time was obviously different from the last time, the air around Shirley was slightly distorted, not obvious, and a faint magic array could be seen.

The 5 test goblins didn't faint either.

Instead, he lowered his head and closed his eyes drunk, and shook his body slightly to the beat of the music, as if he was asleep.

"It seems that different songs have different effects, Shirley, change the song."

The magic circle around Shirley is in general.

The air twisted violently, and a furious storm of red magic sound spread.

The 5 goblins, still in their intoxication, seem to have been put into a meat grinder.

In the sound of puff, they were slashed by thousands of invisible blades, and countless blood wounds burst out of their bodies in an instant.

In just a few seconds, only a skeleton remained.

Roy and the others were startled.

Fortunately, Shirley didn't sing this dragon ballad at the beginning, otherwise she would have slaughtered the Demon King City directly.

"Go on, change people and change songs."

The time for the test took the morning.

These dragon ballads sung by Shirley actually have different effects. There are offensive ones that can stun people, soothing ones that can heal injuries, buff blessings, and some that can be hypnotized.

This kind of magic released through sound was named sound magic by Roy and others.

"Very good, very good. Shirley, you will definitely become the number one idol of our Demon King City. ”

Roy's excited compliment.

Shirley's eyes widened happily, and the dragon's tail flicked back and forth behind her.

Roy suddenly changed his style and said with a smile:

"From today onwards, you're going to let me stay in this room and practice my songs, trying to control the magic of sound. During this time, you have to train hard, reward you with delicious food if you make progress, and eat steamed buns and pickles if you can't control it. ”

"Don't!"

Shirley screamed in despair, she couldn't leave the cafeteria for all kinds of food.

"If you don't want to eat steamed buns and pickles, give me a good practice."

"Woo, boss...... You can't ...... like that."

Roy turned away, reached the door, and called Migg again.

"Go, go in and train with her, and only you can resist those sound magics."

"Yes...... Boss ......"

"What? You're not happy to create a two-person world for you, huh? ”

Mug was stunned for a moment, snapped and shouted:

"Guaranteed to complete the mission!"

After saying that, he rushed in.

There were screams from inside, as well as the sound of **being beaten.

Shirley's sudden display of sound magic was just a vignette.

Demon King City is still developing step by step.

Roy used the designated skin twice before he spawned a main battle skin that was very suitable for the current environment.

【Ice Kingdom】

[Available range: Full range of theme skins]

Rarity: Unique

[Equipment Effect: The target becomes a member of the Ice and Snow Kingdom, and the place where it passes is covered in ice and snow. Gain the Body of Snow, gain Affinity with the Water Element, and gain the ability to control Ice and Snow. All water attack effects are increased by 50%, fire magic effects and defense are reduced by 100%, and they will melt and die in environments above 0 degrees. Gain traits such as Ruthlessness and Silence. 】

[Price: 100W Element Coins]

Somewhat similar to the Cult of Pyro.

After obtaining a skin, you can gain different ice and snow mastery abilities depending on your strength.

In this cold world of bravery, this skin is just right.

Roy immediately decided to buy it.

Come to the outside of the Demon King City and call 100 huskies to test first.

Revoke their Cult of Flame skins and give them new Ice Kingdom skins.

After a twist, a snow husky dressed in white, wearing crystal clear ice armor and holding an ice weapon appeared. The originally clear sky also began to snow heavily.

A hundred snowmen stood in place, motionless.

Roy found that the skinned two words couldn't speak.

They convey simple messages to Roy through their psychic powers.

The bodies of these Erha have also changed, and they have really turned into snow. When they cut through their bodies, they could not see blood vessels and bones, but only a patch of white snow, and the wound would disappear when wiped with snow. Digestion is gone, no food is needed, only mana is needed.

Completely turned into an ice monster.

The temperature around each snow will decrease, and when it gathers together, it will summon heavy snow and low temperatures. These Erha can also unleash Ice and Snow, summoning clones from the snow to help in battle.

In the midst of the snowstorm, they will gain a powerful combat bonus.

They were terribly afraid of the flames.

In an environment above 0 degrees, the body will slowly melt until death.

After a series of tests and a general understanding of Xue Erha's ability, Roy turned all the Sect Huskies into Xue Erha. They are inside the city, which will cause the temperature of the Demon King City to drop and snow heavily. Roy sent Xue Erha out to build the Ice Kingdom in a clearing area that Mugg had detected.

This will be the center of the future puppet kingdom.
