She would have preferred to join in the fight and kill Aeternus. She would have done just that instead of sending the snake demon king off if there was a definite chance of victory. But there isn't a definite chance of victory. She doesn't think the two of them can win against Aeternus. That means that the snake demon king is going to his death, alone. She will join in in case she is wrong and the snake demon king actually threatens Aeternus. Then the two of them can kill him together.
She muttered in anticipation of the upcoming fight, "It is so good to manipulate others. It is almost as good as sex."
Succubi are not particularly strong demons. They have a lot of abilities related to charm, seduction, and illusion but they lack outright firepower either in terms of physical or magical output. They have to be manipulative with what they have since it is foolish to use brute strength.
She engineered this fight and will reap the benefits if there is one to be had and she will do so without risking anything. It is a great feeling. Even the death of the snake demon king will benefit her. She will take his own portion of the wealth before he returns.
That great feeling ended when Aeternus turned to address the threat. Aeternus was going in the direction of his loot when the snake demon king attacked. He was moving slowly. It has been proven that he is very fast. He managed to overtake the snake demon king earlier so he could have left the snake demon king behind if he wanted to escape.
Unfortunately for the snake demon king, he didn't want to escape. In fact, he was hoping that something like this would happen. He sensed when the snake demon king decided to attack him. All he did was turn back and recreate the black beam of energy. The beam tore through the snake demon king's chest and ripped a large hole into it.
The snake demon king was stunned by the blow.
He struggled to speak. "You said it was a one-time trump card."
Aeternus replied, "I lied."
The snake demon king fell to the ground helplessly. He is still alive but the injury made him lose control of his body so his body also enlarged into his full form as he fell down. His small body returned to its 10 kilometers tall original snake form. He crashed into the ground and shook the battlefield with a little earthquake. The snake demon king can be said to be completely neutralized. If nothing is done to help him, he will die a remorseful death.
The succubus queen's happy feeling turned sour immediately. Her heart sank further when Aeternus turned his faceless head to gaze at her. She tried to laugh but all she could manage was a nervous smile. Aeternus was not amused.
He said to her, "You better leave immediately or you'll regret it."
The nervous smile on her face froze. She wanted to complain. She wanted to explain that she wasn't the one who tried to fight him. She wanted to lie that she had nothing to do with the snake demon king's decision to fight him.
But she couldn't say anything. She felt a terrifying feeling of danger. It helped her know that Aeternus is very serious. He will definitely kill her if she doesn't leave. The wealth she has to leave behind is not worth her life so she scrammed as quickly as possible.
She activated her Authority to open a portal back to the abyss. The activation took a minute but she didn't stop even though Aeternus ignored her. He formed some grey chains with his soul force and used them to bind the snake demon king.
The chains bound him up from head to toe. Then they grew black spikes that bore straight into the snake demon king's body so it seemed that he is bound with thorny vines. Then Aeternus stopped the rampage of chaos energy within him from killing his captive.
The succubus queen saw all these happen. She couldn't help but swallow nervously. The snake demon king isn't going to die anymore but she felt more pity for him. She has heard about something like this happening to a lot of demon kings and things didn't end well for them.
Aeternus captured them and no one heard from them anymore. The ones that he released have a tail to tell about how being alive can be worse than death. At least if the snake demon king died he will resurrect in the abyss but now he won't have that chance. He might be imprisoned forever. She was so afraid that she entered the portal as soon as it was opened without looking back.
"Hmm. Hateful bastard. You will regret this. I'll be back and I'll pay you back in a greater amount." She thought to herself as she left the plane.
She has lost a lot of things today. The Celestial Godhood that she got can't make up for her soldiers and the wealth that she is leaving behind. So she won't let this unjust treatment go. Aeternus will be visited with her retribution in the near future.
It was already in her plan to scheme against him before but it was just an idle thought then. Now, it is a must for her to get back at him. She won't be satisfied until her vengeance has been visited upon him.
Aeternus went about his business after that. He raided all the divine kingdoms even the ones belonging to grand gods and high gods. Low gods were not spared either. The entire divine kingdom was pillaged like some defenseless village being robbed by pirates.
He doesn't have to share them with his partners at all so he was happy. His main body chuckled evilly back in his abyssal plane.
"It is all mine as it should be." He said.
He is amused for reasons other than the fact all the wealth of the entire pantheon is now his.
