Originally the King and Prime Minister of the Kingdom of Glotia did not want to attack Ren because it would prove that the Kingdom of Glotia was not under the protection of [Demon King] Ren. But when Darwin continued to woo the King and Prime Minister with glass products with huge profits, the King's and Prime Minister's Greed flared up and was ready to invade Ren's territory. Because at this time no one has produced glass. So if the Glotia Kingdom could monopolize the glass, it could make a huge profit.
As for the news from the eastern empire because the power of the nobles is very limited, the nobles want to rebel and want to summon demons with a very large number of victims. Ren who heard the news frowned because it was actually a bit strange why in the original story there was no rebellion, even though Ren's presence shouldn't affect the Eastern Empire too much.
"Okay, you can go back" Hayabusa disappeared quickly sinking into the shadows. "Kaisel" Ren called Kaisel. Then Ren's shadow began to enlarge and a dark dragon-shaped darkness appeared with cold blue streaks. "Did master call me?" Kaisel asked. Testarossa who saw Kaisel for the first time was quite surprised because she could feel Kaisel's power.
"Kaisel and Testarossa, you will take care of the affairs of the Kingdom of Glotia. I will investigate the Eastern Empire." Ren gave orders to Kaisel and Testarossa. Testarossa nodded and said, "Leave it to us Master, you can focus on investigating the Eastern Empire in peace." Ren nodded and disappeared soundlessly and a shadow appeared in the position before Ren teleported, Ren didn't use [Diverison] to be less conspicuous.

-Testarossa POV
Testarossa who saw Ren had left looked at Kaisel "are we going to attack directly or do you have a plan?". Kaisel shook his big dragon head "We will show how much power Master Ren has so that weak humans won't dare attack Master Ren again". Testarossa nodded, seeming to agree with Kaisel's opinion "Okay, we will attack Glotia Kingdom tomorrow". After that they left the room.
-1 day later
Testarossa and Kaisel exited Ren's territory and headed for the Glotia Kingdom's place, they didn't hide their aura. And it's because of their huge aura that it attracts various powers

-Guy Crimson POV
Guy who received the news about Testarossa's movement became seriously 'Looking for information about Ren's movement'. 'Master, it seems Ren-sama is not moving'. 'Watch Blanc'. Guy sighed because if Ren made a move, the battle impact would be too great. And he had to come to stop Ren

-Glotia Kingdom
It didn't take long for Testarossa and Kaisel to arrive at the Kingdom of Glotia. Testarossa and Glotia immediately released their auras, the people of the Kingdom of Glotia suddenly found themselves under a terrible pressure.
"W-what is this".
"Why do I feel so cold even though it's hot like this today?"
"Q-quickly report to the king" the captain of the guards realized that this pressure was coming from someone and that person was targeting them
