When he found out both of them had a kid and his going to be the next ruler, he thinks that his throne is on stake. He opened his one of the wooden box where he put his Death Seeking Ball.
He put the magical ball on a table and chanted "Oh my dear Death Seaking Ball, tell me who is going to get killed in this war!!!???". A blurry image came out, it was his own image. The anger upon seeing his own image in the ball made his veins pop out. He furiously called some of his servants and brutally killed them all. The blood didn't flow because they are angels lower than him. He knew that angels don't possess the ability to produce blood and nor could they die easily, but in front of Song Rok, anyone could die even if they are angels or Demon King.
He consumed their soul and called his attendant to tell the army to prepare themselves and with a smirk on his face he said, "The time has come...", "even the angels can die by my hands the Demon King is nothing, ha ha ha...". He turned to his magic ball and put it back in its place.
When he turned back, a beautiful angel came from the front door, she slid the curtains and entered the room. Song Rok was sitting on his chair when he saw that she came and sit on his lap. She crossed her legs and with the seductive smile she started to caress his face, then his body. He was so into her that he got seduced easily. While the process still going on, there was a knock on the door. Song Rok, while doing it, let the person behind the door enter the room. It was the general of the military who was serving him, since he became the favourite of the God and the head of all the angels.
He came inside and bowed his head. When he lifted his face up, he saw that Song Rok was currently making out with his beloved lady. The general put his head down and said, "Sorry...! I'll come back later!!!". Song Rok stopped him and said "Just say it... uhh*... or I'll punish you for disturbing me already". The general got scared, he started to say everything "Sir... we came to know that the angel we threw into the demon world is...", "Is what?" Song Rok asked. "Is the little brother of Myronseidon!!!" he said.
Song Rok furiously thrusted, and a very loud moan came from the lady. He was so angry that the guard noticed. He quickly added more words, "But don't worry sir, I got all the info about him. He currently is in love with his son and is hiding somewhere, and the emperor is very tensed because of him".
Song Rok got pissed off. He shouted and said, "So what? Do you want me to give them blessings?". General explained "No sir, the thing I am trying to say is, the emperor is angry on that angel to make his son fall in love with him, and he wanted to kill him. You can use the opportunity to kill both of them and as for his son...", suddenly Song Rok started to get interested into his plan, he said "His son what?". The general said, "I have heard that his son is such a beauty no one can resist... we can capture him and imprison him so that you can enjoy yourself...". Song Rok liked the idea.
