On this day, Qingyin did not return to Xu Chen as tired as usual.

Xu Chen was a little worried and went to the deck to look, but found that the sky and earth had changed, and a grand formation had been formed!

"Xu Chen! Wait for me here! We will definitely rescue Sister Star Dance!" Qingyin said.

"Oh? Can I come with you too?"

"No!" Qingyin shook her head, "Our Four Heavenly Demoness Formation is complete, and the power is endless when activated. If you go, it will only distract us and serve no other purpose!"

Sakiko threw a crystal ball: "Xu Chen, it is also very dangerous for Qingyin to go alone. You can use this crystal ball to watch her every move, so you can feel more at ease."

"Um..." Xu Chen held the crystal ball, struggling to say something.

The treasure ship flew back to the Demonic Capital, and in that huge black void, the four beautiful demonesses of the Demon Realm and Qingyin stood in mid-air.

"Xu Chen! Let's show you the true face of the Four Heavenly Demoness Formation!" Sakiko said.

Suddenly, endless energy gathered on the four beautiful demonesses, and they transformed into four colorful gems, surrounding Qingyin.

"What!?" Xu Chen was shocked.

"Xu Chen!" The gems transformed from the four beautiful demonesses spoke at the same time, "We have temporarily transformed into gems, and Qingyin will take us deep into the 18th level of the Demon Realm! This is the first form of the formation. As for the battle form, you can see it through the crystal ball!"

"But... Qingyin, you go deep into the 18th level, and I... I can only watch from a safe place? This, how can that be!?"

"Xu Chen!" Qingyin's gaze was resolute: "You have saved me countless times, but this time, you have nothing to do. If you go, you will only cause trouble. I will rescue Sister Star Dance. You stay at home... I love you! Be good~!" Qingyin flew over and gave Xu Chen a deep kiss.

While Xu Chen was still savoring it, a hint of melancholy flashed in Qingyin's eyes, but Xu Chen didn't notice. Qingyin leaped forward, like a celestial falling into the depths of the demonic domain, disappearing into the endless abyss!!!

"Qingyin sister!!!" Xu Chen reacted and wanted to stop her, but it was too late. Qingyin, like a dazzling light, gradually vanished into the dark abyss!

Qingyin sister... Xu Chen sat weakly on the deck. He always felt that Qingyin was hiding something from him, but now he was powerless. All he could do was trust Qingyin sister!

"Xu Chen! It is dangerous above this abyss. After all, the four beautiful demonesses of the Demon Realm are not here. Let's go back to the Mercenary Corps headquarters!" Devol came over and supported Xu Chen.

"Yes!" Xu Chen nodded.

After the ship sent Xu Chen and Devol back to the headquarters of the Mercenary Corps in the Demonic Capital, it returned to Floating City by itself. Xu Chen ate some tasteless food, talked a little bit about recent events with Yule, and then returned to his room on the second floor and took out the crystal ball to watch.

The crystal ball seemed to understand Xu Chen's intentions. It flashed with light, and Qingyin's beautiful figure appeared in the darkness. She was wearing a white gauze dress, floating gracefully, resolutely descending into the endless darkness!

This crystal ball was truly magical. It seemed to be able to change perspectives according to Xu Chen's will, zooming in or out, allowing him to see Qingyin and everything around her clearly!

"Qingyin sister..." Looking at Qingyin venturing alone into the darkness, Xu Chen felt unimaginably distressed, but he was powerless! Sister Star Dance must be saved, and now all he could do was watch Qingyin sister, accompany her into the depths of the hellish chaos! No matter what happens, Xu Chen will not evade. He will stay here, bravely watching his beloved go on a dangerous adventure. This is the greatest support Xu Chen can give to his beloved woman!

At this moment, Qingyin flew in the depths of that dark abyss for seven days and nights.

Originally, it was impossible to directly reach the 18th floor.

However, the Four Heavenly Demoness Formation could open the hidden door in that dark place, and Qingyin felt as if there was an invisible gigantic mouth swallowing her at the depths of the 15th floor!

She couldn't see anything for a moment, her consciousness gradually becoming blurred. But she understood that when she woke up again, she would face the deepest and most dangerous level of the demonic realm, the 18th floor - the Dark Prison of Demons; a place devoid of any righteousness, justice, or logic, and ruled purely by evil, power, and desire!

"Xu Chen! I love you!" Tears streamed down Qingyin's cheeks. In the face of endless fear and the oppressing darkness, she held onto her deep love for Xu Chen, as the only beacon of hope to resist the boundless darkness!

A tiny spark can start a prairie fire!

This flickering light will be the sexy yet hesitant Qingyin's only hope to resist the darkness and confront the hordes of demons!
