Thanks for the invitation! I am in hell and have just become a demon king.

"Aqiuka, do you have a ready-made battle formation?"

"You're really rude. No, I don't even know the rules of the Blue Star world. Even if there is a ready-made magic circle, it must be modified."

"So Aqiuka must go with me. And with his Tyrant Army Formula, it will be no problem for him to seal his strength to the sixth level."

"But the underworld can't be left without someone guarding it. If the five of us demon kings disappear at the same time, the underworld will definitely be in chaos. It's so frustrating!"

Chen said pretentiously.

The other three immediately understood. Since Sirzechs is not here now, is there any need to consider who will stay behind?

It's you, Sirzechs.

Aqiuka immediately found a perfect excuse and said:

"Ahem! You all know that I can't seal Sirzechs's destructive power. Once he appears on Blue Star, he will definitely attract the attention of all the Overlords."

"Serafall and I are both weak. We can have Aqiuka seal our strength to the lower sixth level."

"Then it's a happy decision."

The four of them looked at each other and made the decision in unison.

277. [The Mystery of the Origin of the World, Venelana's Madness]

"Your Majesties, His Majesty Lucifer, the Patriarch, and the young ladies are already waiting for you in the back garden."

As soon as the four of them arrived at the front door of the Gremory family's house, they were respectfully led to the back garden by the butler.

"Ding! Found Sona-chan, needs to replenish Sona energy."

As soon as the words fell, Serafall's figure flashed by, appeared behind Sona, and hugged her tightly.

Then, like a pervert, he buried his face in Sona's neck and took a few deep breaths of the familiar light fragrance.

"Sona's energy has been replenished, Leviathan-chan is alive again."

Serafall made a victory gesture to everyone, a bright smile on her pure and sweet face.

The other people's eyes twitched violently when they saw this. They looked at Sona, whose face was flushed and she was filled with shame and anger, with sympathy, and felt lucky that they didn't have such a perverted sister who was obsessed with her sister.

To be honest, Chen gets very curious every time he sees this scene. How does Serafall switch between the two states of perversion and shyness?

"Sister, you are so rude. In front of the four emperors, in front of..."

Cang's head was steaming hot, and he wished he could find a crack in the ground to crawl into immediately.

"Today is just a private party, and there are no demons from the underworld here, so there's no need to be so restrained."

"Sirzex, are you so fast today?"

Chen glanced at Anna, who was sitting next to Sirzechs with a satisfied smile, and asked with a mischievous look on his face.

"I, Chen, you feel uncomfortable every time you don't do anything, right?"

Seeing the strange looks from the others, Sirzechs just missed the days when Gurefia was by Chen's side immensely.

"Chen, leaving so many girls at home to go out and play for so long is not what a qualified husband should do!"

Anna raised her eyebrows and fought back decisively to protect her husband.

"Sister-in-law, I was wrong. I'm not joking anymore."

Upon hearing this, Chen glanced at the women with resentful eyes and raised his hands in surrender.

"I came back this time just to take them out to play."

Hearing these words, the girls' eyes lit up instantly, and they all smiled excitedly.

"Uncle Geoticus, do you mind if I sit here?"

Chen suddenly sat down between Geoticus and Venelana and grabbed the former's wrist.

"Xiaochen, what do you mean?"

Geoticus's expression changed instantly and he wanted to pull his hand back.

"Achuka's guess was right, Uncle Geoticus. You've reached the end of your rope."

While Chen was speaking, he also blocked out their voices, ensuring that what he said next could only be heard by these few people.

"Chen, what are you talking about? I didn't hear clearly."

"Father, what's wrong with your body?" Sirzechs asked with difficulty keeping calm.

Seeing that he had been exposed, Geoticus simply spoke frankly:

"Since Chen has discovered it, I don't bother to hide it anymore. I'm about to die, Venelana. Although I'm really sorry about what I'm about to say, I hope you can treat them kindly for the sake of a dying person like me."

"Are they your illegitimate children?"

Venelana took a deep breath, suppressed the sadness in her heart, and asked in a cold tone.

"So you already knew?"

"I only know of two. As for whether there are more, I don't know."

"There are six in total."

Venelana knew that after today, the love between her and Geoticus was exhausted.

"Geotex, tell me, what do you want me to do?"

"After Sirzechs became the Demon Lord Lucifer, he effectively broke away from the Gremory family. Rias has also married Tatsuya-chan. I hope that the position of the next head of the Gremory family will be given to one of my six children."

"Bang! Geoticus, you're crazy. Don't forget you still have your grandson, Miligas."

Anna forced a smile upon hearing this. She never expected that her father-in-law would be so irrational. It was obvious that Miligas was the most legitimate heir to Gremory.

"Miligas also has the last name Lucifer. With Miligas's talent, he is fully capable of inheriting Sirzechs's throne as the Demon King in the future."

"Chen, I just want to know if my father can be saved?"

"My bloodline essence is about to run out. If Uncle Geotex hadn't possessed the strength of a sixth level and used his magic to suppress it, I would probably be lying in bed right now."

"As for the solution, Aqiuka, is there any hope for Uncle Geoticus?" Chen asked in a voice transmission.

"The bloodline essence is exhausted. The only way is to replenish the lost bloodline essence."

"Aqiuka, can I use my Lord's Origin?"

"Sirzex, you are now a large source of destruction. To some extent, you no longer have demonic blood."

"Only the bloodline origin of the same clan can do it. This is a forbidden method I found from the hidden text of the old Demon King family. However, they use it to strengthen the origin and improve strength."

"Aqiuka, stop talking. Devouring one's own kind is considered a lost demon in the underworld. They only have one fate, and that is death. If other demons knew that this was actually done by the old demon king, how many demons do you think would devour their own kind to increase their strength?"

Chen waved his hand decisively in denial, saying that even if Sirzechs agreed, he would never agree.

Once Gremory takes this lead, the demon clan will probably be in endless internal strife from then on.

"I understand." Sirzechs also couldn't use this method, so he continued, "Achuka, is there any other way?"

"Is the primordial water useful?" Chen suddenly asked.

"No, bloodline essence is very complicated. How should I put it? It's a bit similar to our sovereign essence. Because the depletion of bloodline essence is neither a damage to the soul nor a damage to the body. Life-saving items like the original water repair vitality and soul, it can't replenish them."

"The bloodline of the demon clan is very special. This should be related to our ancestor, the demon mother Lilith."

"Wait a minute, I want to ask someone." He suddenly thought that, apart from the devil himself, the person who knows the devil best in this world should be the creator of biblical mythology - God.

Sirzechs couldn't help but feel a flicker of anticipation in his heart. Chen should be going to ask his mother, God.

Chen: "Mom, how do I cure the exhaustion of the demon bloodline's essence?"

God: "There is no cure, no hope, just wait for death."

Irene directly gave him three consecutive denials, which left him speechless.

Chen: "Is there really no hope?"

God: "The cost is too great, it's not worth it."

God: "The bloodline of demons in our world comes from the mother of demons—the legendary witch Lilith. She was also the first witch born in this world. From her corpse was born the demon clan. The demon clan was the first generation of Lucifer, who was created after the first angel I created fell from heaven. As for the specific process, I don't know what taboo ritual he used to create life from the corpse."

Chen: "Why did Lucifer fall from heaven?"

God: "He won't be beneath me, it's that simple."

God: "Don't talk nonsense. There are two ways to save the demons whose bloodline essence is exhausted. One is to find the corpse of Lilith, the mother of demons. Her corpse is very special. As long as it is placed in an environment with sufficient magic power, the blood and flesh will continue to proliferate. The bloodline of the demon clan comes from her. Only by extracting the essence from her corpse can the demons be saved."

God: "The second is to use the origin of the world. The origin of the world is almost an omnipotent treasure. Anyway, I have never seen a treasure more useful than the origin of the world."

Chen didn't know what to say. When he signed the contract with the Blue Star World, the world consciousness gave him a little bit of the world's origin as a deposit, but asked him to use it to make friends with Elliot.

Because he had no way to refine the origin of the world, the instinct from his soul told him that he could not use the origin of the world directly.

Chen: "Mom, do you still have the origin of the world?"

God: "No, there's not a drop left."

God: "I used them all to create the God-annihilating tools, the Seraphim, and the reincarnations."

God: "And even if you get the World Origin, you can't use it directly, because the level of the World Origin is too high, so high that even the Overlord can't refine it directly."

Chen: "Mom, how do you use it?"

God: "Stupid! Of course I figured it out myself. In my ignorant era when the world was just beginning, the first ancient life forms born in the world all contained the origin of the world. I am the first and only one to discover this energy that can only be used by the world consciousness."

God: "I have to say that the other gods who were born with me were really stupid. All they thought about was fighting and killing. Later, I spent a long time researching how to use the origin of the world. From then on, my road to invincibility began. Otherwise, why do you think I dare to call myself the only god and still not be defeated?"

Mom, it turns out you are the protagonist!

God: "Alas! Back then, I had so much world essence that I couldn't use it all. I miss it so much!"

Chen: "Mom, I have signed a contract with the World Will of Blue Star. As long as I can help Him drive away those overlords, He is willing to share a portion of the world's authority with me. Then we will have a steady flow of world origin."

God: "Well done! I never thought there would be such a generous world will in the endless chaos."

Chen: "If I have the origin of the world in my hand, can you save people, mom?"

God: "Xiaochen, the origin of the world is a very special energy. Whoever refines it will be marked with that person's mark, and no one else can use it. Because the level of the origin of the world will actually decrease slightly during the refining process."

God: "That's why I said there's no hope. Don't waste time. Lilith's body hasn't appeared in countless years. God knows where in the world it's sealed now. As for the other method, it's also unrealistic. Even if you have the origin of the world in your hands, it's impossible to create a secret method suitable for the demon clan to refine the origin of the world immediately. I remember it took me more than 10,000 years to succeed."

Chen: "Mom, I understand. Sorry to bother you."

God: "It's okay, I'm very free now, but Xiaochen, when will you come to heaven? I miss you so much."

Chen: "Wait until I finish what I'm doing."

God: "Mom is waiting for you in Heaven. You promised to visit me once a month, but you didn't keep your promise. If you stand me up again, you're doomed!"

Seeing his mother's threat, Chen promised with a cold sweat in his heart: "I promise."

..........................................

"Sirzex, there are two ways, but neither is practically feasible. The first is to find the body of Lilith, the Demon Mother. I'm not comfortable discussing the second method, but it will take at least ten thousand years to successfully research it."

"Is it really related to the Mother of Demons?" Aqiuka muttered to himself when he heard it.

"Chen, thank you for taking the trouble to help me. I have been mentally prepared for this. If blood decline is really so easy to treat, then there wouldn't be any demon king-level strongmen who seal themselves. Every major family has a few sealed and dormant antiques."

"Father, why don't you also seal yourself and sleep in the family mausoleum like our ancestors?"

"Live like a corpse, barely breathing? Sorry, Sirzechs, I'd rather face death calmly. Besides, the Sleep Seal only means a little longer life."

"Mother, how about you try to persuade father?"

"Sirzex, can't you see? Your father held on for the last few days because he couldn't let go of his six children. He was afraid that I would kill them one day."

Venelana sneered with a sneer on her face.

"I believe you are not that kind of person, mother."

"Sirzex, you are not a woman, and you don't understand women."

"Xiaochen, do you think I'm right?"

"Ah, this... I don't express my opinion, but the fact is that few stepmothers will truly treat a child that is not her own."

"Besides, demons are all cunning and treacherous. It's rare to find someone as righteous as you, Sirzechs. And if Aunt Venelana really did take action, what could you do to her?"

"I, I, I." Sirzechs scratched his red hair in pain. At this point, he suddenly found that he seemed to be unable to do anything.

"So when it comes to conflicts between elders like this, we, as the younger generation, just need to listen to how they handle it."
