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

"Don't worry, since I dare to bring her to you, I am sure of this."

"Bronya, it's your turn now. Show your future teacher what you're best at."

"Well, Bronya knows."

As soon as he finished speaking, countless data streams flashed in Bronya's silver-gray eyes, and the space behind him began to fluctuate violently. One by one, the Keys of Truth slowly appeared in front of everyone's eyes.

"The law of truth, constructing everything?"

"Aqiuka, is she qualified to be your disciple now?"

"Well, you're really amazing. Where did you find such a follower?"

"It's a secret."

Aqiuka did not expect to get a real answer from Chen, and said to Bronya with a pleasant face:

"Bronya, huh? From today on, you can call me Mr. Achuka."

"Yes, Mr. Achuka, Bronya will try his best."

"Sirzex, come here, I have something else to trouble you with."

A bad feeling suddenly emerged in Sirzechs' heart.

Chen said as he pushed out Xilin who looked eager to try. But before Chen could finish, he heard Xilin say proudly:

"You are the devil Lucifer who holds the power of destruction. I want to challenge you."

As soon as the words fell, the aura of Xilin, a seventh-level master, instantly burst out, and the alarm in the Demon King's City sounded instantly.

"Idiot, I told you long ago that this is the Demon King's Castle, and you are not allowed to casually show off your power. Also, when you call me senior, you should show some respect."

Chen didn't hold back and knocked him on the head, saying unhappily.

"Okay, I get it now."

Xilin instantly put away her aura, hugged her little head with both hands, and said with tears in her eyes.

Damn it! How dare this bad guy hit her head so hard? It really hurts!

"As you can see, this little girl just broke through to the seventh-level Overlord, and her heart is starting to get bigger again. Sirzechs, please help me educate her for a while."

"By the way, Xilin wields the power of the end, which has something in common with your power of destruction."

"Chen, where on earth did you find this pervert?"

"I told you it's a secret. You'll know it later."

"Okay, now that the matter has been resolved, I have some things to do in the human world, so I'll leave first. We can talk again when we meet later."

After Chen finished speaking, he didn't give the four people any chance to react, and ran away with Rita, Shabu and Xier.

"This guy Chen is really skilled at being a hands-off shopkeeper!"

Sirzechs said with a wry smile upon seeing this.

"It's not bad. Chen has sent me a well-behaved disciple and a capable assistant. As for you, it seems that your luck is not so good!"

Aqiuka said with a gloating look on his face.

Bronya's Law of Truth can help him in many ways, and seeing this little girl sitting quietly on the sofa after Chen left, she looked extremely well-behaved and quiet.

As for the other girl, Xilin, she is simply a troublemaker and a naughty child.

As if he treated the devil's office as his own home, he began to wander around excitedly, touching here and there from time to time.

“It’s such a headache!”

"But the scariest thing is that red-haired girl. I actually felt a strong sense of threat from her."

"I feel the same way. I don't know where Chen found this god from!"

…………

"Bronya, my name is Seraflor. Can we get to know each other?"

Seraphlu dropped the official business in her hands, suddenly ran to sit next to Bronya, and asked in a friendly tone.

"Hello, Seraphlu-senpai."

"Bronya, how did you get to know Chen?"

"Bronya can't tell you this, but Senior saved Bronya and Celine when Bronya was most helpless, so Bronya is really grateful to Senior."

Bronya's eyes showed a hint of admiration, and he said with a firm face.

"Are you from the same place?"

Bronya remained silent because she knew that talking too much would lead to mistakes.

"Are those girls who came with Chen just now also in your group?"

Bronya remained silent.

"Ahhh! What an unlovable little girl."

Seraflor just wanted to find out about the backgrounds of these girls. She had only known Chen for such a short time, yet their relationship was already so close.

In contrast, she and Chen have known each other for more than a thousand years, but their relationship has not made any progress.

"Seraflor-senpai, your tsundereness ruins your life."

"Hahaha! Bronya, what are you talking about? Why don't I understand?"

Seraphlu laughed, turned around and slipped away.

"Hey! Lu, Sirzechs-senpai, when are we going to compete? I can't wait."

After walking around, Xilin finally said a little impatiently.

"Then let's leave work early today, Xilin, and come with me."

Sirzechs said with a headache on his face as he set up a magic circle leading to the Gremory territory.

"Bronya, let's go too."

"Yes, Mr. Aqiuka."

Bronya quickly stood up and followed Achuca.

"Flat Loli, don't let me pull you down too much! Otherwise I will look down on you."

Before leaving, Xilin said hello to Bronya and spoke in a bad tone.

"Humph! Bronya will beat you to a pulp one day."

Bronya hated hearing this name the most. A fierce look flashed in his eyes and he said it expressionlessly.

"Haha! Let's talk about it when you break through to the seventh level."

-------------------------------------

The Gremory family castle.

"Brother, why did you get off work early today?"

"Ah! Brother, who is this girl?"

Rias, who was playing with Miligas, was originally curious about why her workaholic brother came back so early today. Unexpectedly, she saw a girl with a figure and appearance that was not inferior to hers walking out of the magic circle.

Miligas was also stunned. His father, who he always thought was a good man, would actually bring a girl home today for the first time. Could it be...

"What the hell are you two thinking about?"

Sirzechs saw the expressions on his sister and son's faces and instantly guessed that they must be thinking the wrong thing.

"Rias, what happened?"

Because of Rias's scream, Venelana and Anna dropped what they were doing and rushed into the living room.

"It's just right that you're all here. Let me introduce you. This is Chen's dependent, Miss Xilin, who is currently studying with me."

"This is my mother, Venelana, my wife Anna, my sister Rias, and my son Miligas."

Sirzechs introduced his origins to both parties.

"Wait a minute, Sirzechs-senpai, unless you can defeat me, I will leave. I will not study with a senior who is weaker than me."

Xilin crossed her arms and said proudly.

"Where on earth did you come from, you wild girl? My brother is a transcendent of the demon clan, and you still want to challenge him?"

Rias finally couldn't stand it anymore and questioned jealously.

Why did her fiancé have a new family member after not seeing him for a while?

However, if Rias knew the number of girls around Chen, she would definitely be jealous and crazy.

"I don't talk to the weak."

Sirin glanced at Rias, then looked away, looking down at her with contempt.

A fifth-level scum, Queen Xilin was too disdainful to communicate with such an ant.

"I am Chen's fiancée."

Xilin was stunned for a moment when she heard this, then she laughed wildly, almost crying.

"Hahaha! Did I hear correctly? A weakling like you at level five is actually that villain's fiancée. When did that villain's vision become so poor?"

Rias was furious when these words came out. Her pretty face flushed red, and her chest heaved as she said:

"I'm not a weakling. I want to challenge you."

The others were speechless. Although they knew that Rias was not worthy of Chen for the time being, it was too much to say it so bluntly!

Venelana and Anna pulled Sirzechs aside and said angrily:

"Sirzex, what is the origin of this little girl?"

"I don't know either. Chen came to the Demon King's Castle in the afternoon and asked me to help educate Xilin for a while."

"Even so, this little girl is so rude. It's her first time visiting our house, and she's so disrespectful."

"Mother, she has reason to be proud."

However, over here, when Sirin heard Rias say that she wanted to challenge her, she laughed even harder.

"Did I hear correctly? You, a weakling, actually want to challenge me, Sirzechs-senpai. Could it be that the villain is marrying your sister just for your sake?"

Sirin asked, turning to look at Sirzechs.

The truth is!

Upon hearing this, a burst of destructive magic power instantly burst out from Rias' body. If she hadn't had a little hesitation in her heart, she would have rushed up and fought to the death with this annoying guy.

"Rias, stop it. You are not a match for Sirin yet. She said she wanted to challenge me, and I agreed because Miss Sirin is already a seventh-level master."

What? What did she hear? This guy, who looked about the same age as her, was already a seventh-level master. Was he kidding?

Rias was petrified instantly, standing there in a daze, unable to utter a word. If there was a crack in the ground, she would definitely crawl into it immediately.

How shameful! She actually had the audacity to challenge a seventh-rank master.

"Brother, you are not kidding, right?"

Rias still found it hard to accept this fact and asked in disbelief.

“It’s incredible, but it’s true.”

"Miss Fiancée, I suddenly realized that the weakest people around that bad guy are stronger than you. This is really interesting!"

Upon hearing this, Rias was so angry that she trembled all over. This guy was so despicable that he actually mocked her like this!

"Don't be complacent. Although I can't compare to you now, I will definitely challenge you in the future and wash away the shame you gave me today."

"Then I'll wait and see, Miss Fiancée."

Xilin said with a mocking look on her face.

"Sirzex-senpai, let's begin now."

The group arrived at the training ground, the magic crystals were charged, and a huge magic circle slowly rose up, covering the entire training ground.

"This magic circle can withstand a full-strength attack from a seventh-level opponent. Xilin, you attack first."

Sirzechs spoke gently as the two men standing on the training ground slowly rose into the air.
