When Shen Ling opened his eyes, what broke into his eyes was a soft white.

It is a small grove with sparse trees and a thick layer of white snow on the surface and canopy.

But Shen Ling didn't feel cold, the mild sun above his head made him feel a warmth, but the first time he saw this, he felt a sense of intimacy.

He was now at the foot of a snow-covered mountain, the peak of which blocked his view, and he spread his wings and flew into the air, stepping on the top of a large pine tree at the top of the peak, and saw the small world clearly.

On the other side of the mountain is a snow-covered forest, and along the edge of the forest, a steep cliff at the end of the cliff emerges out of thin air.

Shen Ling's vision was very good, even if he was far away, he could clearly see the castle floating in mid-air, and at a glance, he was shocked by the beautiful castle.

The castle was made of crystal or ice, the walls were smooth without any traces of joints, and the soft sunlight was a dreamy ice blue.

"It must be a mermaid's castle!"

Both Ash and Phoenix were excited by this beautiful castle, and Shen Ling also impulsively wanted to fly over and enter the castle as soon as possible to see what kind of secrets were hidden inside.

He spread his silver wings, and before he could start flying, he suddenly felt a gust of wind behind him, and the next second, he was pushed down from a pine tree and pounced into the snow.

The snow was so thick that the two men sank into it, leaving a large crater in the shape of a man on the top of the mountain.

The person who came unceremoniously bit Shen Ling's shoulder, Shen Ling screamed in pain, the strength of the person behind him was too great, he couldn't struggle at all, in fact, he didn't dare to struggle.

He felt his anger in the heavy gasps of the man behind him.

"You've left me again......" Ludwig wrapped his arms around Shen Ling's waist and enveloped him beneath him, his violent aura constantly overflowing from him.

"I didn't leave you." Shen Ling softened his voice to comfort him. "Even if you're not with me, I'll find you as soon as possible."

Ludwig buried his face in Shen Ling's side neck socket, and after a long silence he calmed down and let go of Shen Ling.

"You get up." Shen Ling knew that Ludwig was unstable at the moment, so he could only coax him, "Don't worry, I won't go anywhere." ”

Ludwig stood up and pulled Shen Ling by the way.

Shen Ling was pulled into a warm embrace, and when he looked up, he crashed into Ludwig's dark eyes. He looked at him quietly, a cold light shrouded in the handsome face carved by the knife and axe.

The blow was too heavy for him back then, and it made him as sensitive and irritable as he is now.

Shen Ling sighed in his heart, when would he be able to let Ludwig really come out of the blow of the year.

Phoenix and Ash were wondering when Ludwig had approached, and why the two of them hadn't noticed it in the slightest—

The air of the forest was forbidden, and it was forbidden to fly or use modern means of transportation, so Shen Ling and Ludwig could only walk through the forest on foot.

The frozen forest was not large, there was no sound except for the footsteps of the two of them, and it was eerily quiet. Shen Ling didn't see any other creatures along the way, and the phoenix gave him an affirmative answer.

"There's not a single insect in this forest except for plants."

"Is it dangerous?"

"If these trees are dangerous...... Wait, you stop!"

Shen Ling stopped, Ludwig looked back at him strangely, he smiled, gestured, etc.

"See that snowball on the ground? Break it open."

Shen Ling squatted down and began to pull the snowball in front of him according to the phoenix's instructions, and when he pulled all the snow on the surface, there was a little rabbit frozen in it.

The little rabbit was encased in a pale blue ice crystal in a running form, with its two hind legs kicking the ground and its front legs still in mid-air. It seems to be alive as if whoever presses the "start" button will run happily through the forest again.

Ludwig also squatted down to check on the rabbit, and he and Shen Ling looked at each other without speaking.

Then, Shen Ling found a lot of animals that had been "suspended" by the ice in the process of traveling.

He involuntarily quickened his pace, but luckily the forest was not large, and a few hours later, they came out of the forest and into a small town with relatively modern facilities.

The town is also silent, and there is not a single person in sight on the snow-covered roads. But the snow pillars on the side of the road shocked Shen Ling.

He walked to the nearest pillar of snow and pushed the snow away little by little. Ludwig also came to his aid, and soon after, the two pulled the upper body of the snow pillar out. It's a beautiful girl, with a shallow smile in her blue eyes, as if she's playing with someone.

Shen Ling thought of something, and carefully pulled out the lower half of the girl's body.

When he saw a white scale, the two soul beasts in his heart said at the same time, "Sure enough."

Soon, the girl's slender and beautiful fishtail appeared in front of the two.

"Is this the reason why the merfolk are exterminated?" Shen Ling muttered to himself, then shook his head again, and looked at the castle floating in mid-air, maybe there would be an answer there.

He and Ludwig soon reached the foot of the Ice Crystal Castle, which was floating above the cliff and connected to the ground with a suspension bridge made of ice crystals. At the other end of the suspension bridge, there is a closed ice crystal gate more than ten meters high, and the gate is carved with intricate and beautiful strange patterns.

Shen Ling couldn't wait to step on the ice ladder, and when he walked to the door, he put his hand on the door. A powerful vibration of soul power reached his heart from the place where the door touched his palm, and he only felt his heart tremble violently, and his internal organs were almost shattered by this powerful force.

He withdrew his hand and took two steps back, and if Ludwig hadn't caught him in time, he would have rolled down the ice ladder.

"Soul power on the door? Let me see." After getting Shen Ling's permission, the phoenix jumped out of Shen Ling's body and slammed the gate twice with its claws, each time there were electric sparks, but the gate still didn't move, the phoenix let go of the claws that hurt twice, and said helplessly, "This damn door can't be opened."

At his voice, the door creaked, and someone pushed a small crack open from the inside.

The two soul powers, which were so powerful that they were visible to the naked eye, fought fiercely with each other and overflowed from the small slit, Shen Ling dodged to the side, only to see the two soul powers entangled and rushed towards the ice crystal ladder, "bang", it exploded like fireworks, and under the impact of the soul power explosion, the middle part of the ice crystal ladder was blown up, and the crystal fragments collapsed in all directions.

"There's a fight inside, you get out of the way, let me come." Ludwig grabbed the edge of the ice crystal door with his hand, and with great force, he broke the door open enough for one person to enter.

Shen Ling looked inside from the side of the door, and countless fireworks of soul power explosion in the hall. After getting used to the light of the soul power explosion, Shen Ling saw clearly that there were more than a dozen light-colored mermaid souls fighting with a similar number of human souls.

The scene of the fight was not unintense, the entire hall was filled with soul power, Shen Ling deeply admired the person who built this ice crystal castle, the fierce fighting inside could be completely covered by the castle, if it wasn't for this door to open, there would not be the slightest movement outside.

Another soul bomb flew out of the hall, Shen Ling suddenly felt a light under his feet, and Ludwig took him aside and dodged the soul bomb.

"You're finally here!" The lofty soft female voice sounded in Shen Ling's heart, and Shen Ling was stunned for a moment, and he felt that this voice was very familiar.

"Kid, get to the top of the castle and stop the Invisible Man!"

"There are invisible people here?"

"Disgusting invisible people, they want to break the confinement of our people and escape from here, and they want to take away the treasures of our people. Don't let them leave this castle, or these 10,000-year-old ghosts will turn the outside world into a purgatory!"

"I can't get in, as long as I enter the castle, I will immediately be affected by these two souls that are the same as fire and water."

"Don't be afraid, the merfolk have never been cowards! Boldly step in and we will protect you, go to the top of the building, and kill the invisible man who is attached to the human body!"

"I can't hurt him, I don't have soul power anymore."

"Don't be afraid, you just need to kill his **, and we will seal his soul."

Shen Ling was willing to believe what this voice said, because he could feel the kindness of people of the same clan from the voice.

He turned to Ludwig and asked, "Do you believe me?" ”

Ludwig smiled and asked him, "What do you say?" ”

Shen Ling held Ludwig's hand and said solemnly, "Come in with me." ”

"Okay." Ludwig agreed without hesitation.

Hearing Shen Ling's words, the phoenix that had turned into an entity obviously flicked on the floor. "Do you really believe this woman? You're crazy, what if she's lying to you?"

"I believe in him." After answering the phoenix simply, Shen Ling called him back into his body, and the energy consumed by the phoenix's transformation into an entity was too great, and he couldn't bear it a little.

He took Ludwig's hand and walked into the castle with him.

At this moment, the castle hall is like a three-dimensional abstract oil painting, with various colors colliding and gluing, and the sound of ping-pong explosions is constantly sounding. The merfolk and the invisible people are scuffled together, with different expressions on their faces, some unwilling and resentful, and more undying hatred.

A female mermaid came out of the scuffle and flew towards Shen Ling, her long golden curls automatically unwinded behind her, constantly undulating. Her appearance is very gorgeous, and her figure is more blood-pumping than her appearance.

Shen Ling felt that she was very familiar, as if she had seen it somewhere, but with such a dazzling and charming appearance, if he had really seen it, he would never forget it.

"Follow me!" The female mermaid didn't want to waste any more time, so she flew in front of Shen Ling and immediately turned around and flew towards the center of the hall battle group.

It's the female voice who talks to herself outside!

Shen Ling hurriedly followed with Ludwig.

Ludwig couldn't see the merfolk, and all he could see in this hall was countless energy collisions and explosions. In his eyes, this place was definitely a dangerous place, but Shen Ling's tone and eyes made him feel that in the world he couldn't see, someone must have said something to Shen Ling, and that person had Shen Ling's trust.

Strangely, those soul bombs didn't reach them. It was as if someone had opened an invisible protective shield around them, and the moment all the attacking soul power touched them, the power rapidly shrank and then disappeared.

This made Ludwig even more convinced that someone was by Shen Ling's side, and Ludwig had never been so eager to see the world in Shen Ling's eyes as he was today.

Shen Ling followed the mermaid up the spiral staircase, and when he looked up, he realized that this castle was even taller than it looked outside.

The outside is only a dozen stories high, but when you look at it inside, you feel that this castle is straight to the sky, and you can't even see the top at first glance.

The female mermaid stopped in the air, turned her head to Shen Ling and said, "Fly up."

Shen Ling immediately spread his wings and took advantage of the situation to hug Ludwig. The female pointed to Ludwig, "Please let him fly up on his own!"

Shen Ling paused for a second, and suddenly a feeling that something was wrong suddenly appeared in his heart. He glanced up at the castle's unbounding roof, then at the soul bombs that were still flying in the hall, and suddenly, he understood something.

"He's a dragon, he can fly." The female mermaid continued to persuade.

"Is there really an invisible man up there?" Shen Ling narrowed his eyes and stared suspiciously at the mermaid's eyes.

"Please protect our treasures for us." The mermaid lowered her eyes, and there was a humble earnest in her voice. "Otherwise, the merfolk will perish today."

Shen Ling's heart trembled.

Ludwig found that Shen Ling had been staring at the air somewhere for a long time, and he knew that Shen Ling was talking to someone he couldn't see at the moment, and he wouldn't open his mouth to disturb him, but the resentment in his heart was even deeper.

Shen Ling lowered his head, leaned over to Ludwig's side, and said a string of words with his lips close to his ear.

"I'll be with you." With that, Ludwig's body began to swell, his clothes and pants were torn to the ground, and a pair of bat's wings stretched out on his back, and the skin on his body was covered in a layer of dark red scales.

The dragon's head was held high, and it let out a loud roar.

Shen Ling flew up, hugged Ludwig's head, kissed him twice on the cheek, and looked at the female mermaid again.

He said indifferently, "I'm willing to go up because I want to save the merfolk people."

Shen Ling and Ludwig flew up to the top of the castle together until their figures turned into two small black dots. The female fell to the ground weakly, her blue eyes filled with tears.

In the castle hall behind her, all the fighting stopped in an instant, and all the sounds disappeared in an instant.

The thick and colorful oil painting has become a realistic hell scene, on the bright ice crystal floor, a bloody human corpse lying messily, the bright red blood has coagulated, but the smell of fish never wants to go away.

More than a dozen mermaid souls flew out of the void and stood behind the mermaid.

"Shay, don't blame yourself."

"This is our last resort, only by offering the sacrifice that the sea god desires the most, can the merfolk be resurrected and the invisible people can be contained."

"We only hope they can live up to our hopes."

Shay closed his eyes.

A few minutes later, a dazzling golden light burst from the top of the castle of ice crystals. At the same moment, in the alien beast forests of several planets on the letter D galaxy, several energy crystals hidden under the water suddenly burst out with the same huge golden beam, and the golden beam broke through the top of the mountain and broke through the sky.
