Several months later, the Four Demonic Sisters had already mastered the most basic essence of the Heart!

The Maiden of the Celestial Realm had been practicing with Xu Chen the whole time. However, when Xu Chen suggested applying the Stained Skin to her abdomen, she firmly refused.

Xu Chen didn't insist. After all, he was truly dedicated to his training and didn't want to misunderstand The Maiden of the Celestial Realm. Also, he couldn't stop worrying about Star Dance. He couldn't possibly focus on anything else!

"For the remaining time, you can continue to contemplate here. If you feel that you have grasped the essence of the Heart, you can leave and return to the Demon Realm," Xu Chen said to the Four Demonic Sisters and Qingyin.

It wasn't that Xu Chen didn't want to stay in this enchanted world with the Four Demonic Sisters. It was just that he couldn't disregard Star Dance's safety. Since he had completed the training he wanted to do, there was no need for him to stay in the time-slowing enchanted space. Instead, he returned to the ship.

Casually meditating, a few days passed.

And after contemplating the essence of the Heart, the Four Demonic Sisters and Qingyin also came out!

At this moment, the flying ship was already very close to Meng Yan Country.

The Yin Qi grew heavier and just standing on the deck and looking towards the eerie and gloomy mist in the distant kingdom, one could feel their soul being stabbed with pain!

"Meng Yan Country only has two identities: people of Meng Yan Country and those enslaved by the Sheng Class. Any other creatures that enter Meng Yan Country will be attacked by the extremely intense gloomy aura and have their souls tortured!" Xianzi said. It was clear that she was not relaxed at this moment either.

"Everyone, use the essence of your minds to protect your souls," Xu Chen said.

The girls closed their eyes silently, activating the essence of the Heart within them, forming a hazy transparent halo enveloping their souls.

Sure enough, they immediately felt comfortable.

The fierce and gloomy aura of Meng Yan Country couldn't affect their souls anymore!

"So, the reason you asked us to train is for this?" Xianzi suddenly realized.

"Yes! I felt the terrifying gloomy aura of Meng Yan Country from a far distance. If we don't prepare, even the strongest person who enters will continuously suffer damage to their soul. Even if they don't die, they will greatly lose their combat power! Perhaps this is the reason why no matter how powerful the outsiders are, once they enter Meng Yan Country, they can't come back!" Xu Chen explained.

Zi Wan blushed and took a step forward. "I'm sorry, Xu Chen. I misunderstood you before. It's actually my own ignorance..."

Xu Chen smiled. "Zi Wan, it's not your fault. We are all partners. There's no need to take it to heart!"

Qingyin said, "We are about to enter Meng Yan Country. Let's prepare our equipment!"

"Yes!" The other beauties returned to their rooms to bathe, change clothes, and ready their weapons and treasures.

At this time, in Meng Yan Country, which is tens of thousands of miles away from the flying ship, inside the most mysterious, dark, and gloomy kingdom in the entire Demon Realm...

There is a solitary castle, standing tall on the desolate and gloomy Silent Spirit Wilderness.

On the top floor of the castle lived a woman dressed in white.

She had long blue-purple hair, a beautiful face, and a graceful and enchanting figure.

She was Star Dance.

At this moment, she was imprisoned here all alone. In the vast and cold room around her, hundreds of swords and blades were placed.

And Star Dance's task here was to engrave these weapons!

After being captured by the Ghost King, Star Dance played chess with him while desperately thinking about how to protect herself!

Without a doubt, it was impossible for a woman like her to stay untouched while being with the Ghost King for a long time, so she had to find a way.

She knew that she couldn't defeat the Ghost King, so she racked her brain to come up with a unique skill. Since arriving here, she had been granted a certain special ability. She refined and elevated this ability, and at the most critical moment, she had a breakthrough!

Star Dance became the most skilled weapon engraver in the entire Demon Realm.

At the moment Star Dance engraved the legendary mark, she was discovered by the powerful ruler of Meng Yan Country!

He made contact with Star Dance through his consciousness and made a deal with her. He would use a large amount of treasure to buy Star Dance from the Ghost King and ensure that she would not be harmed. The condition was that Star Dance had to engrave weapons for him for the rest of her life.

Unable to resist the temptation of the treasure, the Ghost King sold Star Dance to the Mengyan Kingdom and used the wealth to rebuild his own kingdom. Although the Ghost King didn't want to part with Star Dance, he couldn't refuse the face of the Mengyan Kingdom's lord. He couldn't deny the exorbitant price offered by the lord, so he honestly sent Star Dance here.

Star Dance is not a wandering soul and cannot become a puppet. However, she also didn't gain the identity of a person in the Mengyan Kingdom. Therefore, the lord of the kingdom placed Star Dance here and as long as she didn't leave the top floor of the castle, her soul would be safe from the invasion of the Mengyan Kingdom.

From then on, she engraved weapons here.

She had never seen the lord of the Mengyan Kingdom. Every day, several ghosts would bring a large number of weapons for Star Dance to engrave, and then they would take away the ones that had already been engraved.

Day after day!

There were so many weapons to engrave every day that Star Dance had almost no time to rest. She felt like a machine, constantly forced to engrave for the lord of the Mengyan Kingdom.

Once, she became depressed and too suppressed, and she neglected to engrave a few times. Whether it was not engraving in time or not achieving the best quality, two horse-faced figures holding sickles would come in. They wouldn't hit or scold her, but they would tie her up and hang her on the cliff outside the castle, exposed to the gloomy soul-sucking wind of the Mengyan Kingdom.

The slow but endless pain to her soul made Star Dance, a strong and intelligent girl, almost collapse...

From then on, she dared not have the slightest slack. She engraved with all her might. However, the number of weapons brought in every day increased, seemingly endless. She also felt more and more tired, more and more unbearable...

"Xu Chen, Qingyin, Izayoi..." Star Dance took out a sad short knife from her sleeve, "I don't know if I will ever be able to see you again..."

She put the short knife back into her sleeve, but she knew that maybe one day, when she couldn't bear it any longer, she would use that knife.
