章 376: Bad news

The sound of the siren began to wreak havoc throughout the imperial palace, so one of the guards who was near the laboratory.

He swallowed hard and opened the door, wanting to know what was making the sound.

When he entered, he sighed when he saw that it was some crazy invention of the herald Einar. "Konungar Einar, the noise of his invention is creating havoc in the imperial palace."

Einar stopped and put his hand on his face as he realized that he had made a big mistake because he had not taken into account where he was.

"Inform everyone that it was an invention and I want them to bring Seren as I require their artisans."

The guard gave a military salute and left the scene.

Einar just sighed and looked at his son. "What do you think of this little test?"

Daven spread his hands joyfully. "Surprising. I didn't know a sound like that could be made just using air."
