Martin suddenly pulled his hand back, breaking free from Count Lucy's pull, and turned to Captain Luo Jia and said, "You will camp outside for the time being and wait for my news at any time to prepare for departure."

After that, he motioned for Eric and Shuang Ning to follow. With these two people accompanying him, Martin felt particularly at ease.

Led by Count Lucy, Martin entered the Magic City. As soon as he entered the city, a strong magical element hit him, much stronger than outside the city. It was indeed a perfect place to practice magic.

Along the way, Count Lucy talked incessantly, introducing all kinds of novel and interesting things in the magical city.

Soon, they arrived at the Duke's Castle. The castle was vast and magnificent. Martin and Countess Lucy boarded the magic carriage, while Eric and Frost sat in the back.

The carriage traveled for a long time before finally arriving in front of a huge magic tower.

After Count Lucy negotiated with the magician guarding the gate, the door slowly opened. She walked in first, followed closely by Martin, Eric, and Frost.

Stepping into the magic tower, Martin was amazed by the scene inside. Everything around him was full of mystery.

He looked around curiously, and Count Lucy quickly reminded him, "Don't touch anything. Everything here is very dangerous."

Everyone arrived at the reception hall, and Countess Lucy took her leave. Soon, several servants brought cakes, fruits, and black tea and gently placed them on the dining table.

Martin had no intention of eating. He sat on the chair. Eric and Shuang Ning stood quietly behind him, waiting for their master to arrive.

Not long after, an elegant elderly woman walked into the hall with steady steps. She had a beautiful face, snow-white hair, and exuded an innate aristocratic air. Count Lucy followed respectfully behind her.

The old woman walked into the reception hall, her eyes passing directly past Martin and falling on Eric and Shuang Ning behind him. She couldn't help but blurt out: "Amazing, really amazing!"

Then, she looked at Martin with admiration. At this moment, Eric and Shuang Ning suddenly flashed and quickly stood in front of Martin.

It turned out that as soon as the old woman appeared, they keenly sensed a strong sense of danger.

Only then did Count Lucy notice that the two people who had been following Martin silently were actually Sky Knights. She couldn't help but widen her eyes in astonishment, with disbelief written all over her face.

The old woman was the first to break the silence and said in a gentle voice: "Hello, little Martin, I am Duke Merlin." As she spoke, she waved her hand, indicating that everyone didn't need to be so nervous.

Martin looked at Eric, who nodded slightly. Then, at Duke Merlin's invitation, Martin and Duke Merlin took their seats.

As soon as he sat down, Duke Merlin spoke again: "Little Martin, you are really young and promising. You have such terrifying fighting power around you. If I am not mistaken, the two behind you are a dragon knight, right?"

Count Lucy, standing nearby, was once again stunned. True dragon riders were rare on the entire continent, and she had never expected to see one in person.

Martin was also shocked. He didn't expect that Duke Merlin would see through his true identity at a glance when they met for the first time.

He gathered himself and said, "Greetings, Duke Merlin. I've long heard of your name. I've come to exchange a C-rank creature growth magic circle with you."

Duke Merlin smiled slightly after hearing this: "Originally, after hearing Lucy mention you, I was planning to give you a B-level magic circle."

"However, after meeting your dragon knight, I think I can increase my investment in you. So, I've decided to give you an S-rank magic circle."

At these words, Countess Lucy's mouth dropped open in disbelief. S-class magic circles were extremely rare, and even Merlin's Magic Tower didn't have many.

Martin was genuinely shocked when he heard this. He didn't dare to accept such a gift that fell from the sky out of nowhere.

So, without hesitation, Martin said, "Duke Merlin, I really can't accept this thing if you act this way. Even if I take it, I have to take it clearly and openly. Why don't you just tell me what you need me to do?"

After hearing this, Duke Merlin showed a meaningful smile on his face and said slowly: "Don't worry, little Martin, this is just a piece of cake for you."

"When you marry Xiao Ba in the future, you must give birth to a boy first, and then you can consider having children with other girls."

When Martin heard this, he secretly exclaimed in his heart: "Good guy!" However, at least he figured out Duke Merlin's intentions, and the big stone in his heart finally fell to the ground.

After all, the unknown is what scares people the most. After a moment's thought, Martin nodded and agreed.

Let’s worry about the future in the future. Now that we have this S-level biological growth magic circle, the little guys in the Valley of Beasts will surely be able to grow rapidly.

Seeing Martin's agreement, Duke Merlin immediately picked up the communication crystal and issued a command. Not long after, a petite girl came bounding over.

As soon as she saw Duke Merlin, she jumped into his arms like a happy little deer, and handed him an S-level magic circle.

Duke Merlin smiled, but did not reach out to take it. Instead, he said softly, "Xiao Ba, you should give it to Martin yourself."

The girl called Xiao Ba squirmed in Duke Merlin's arms for a long time, her face flushed.

Finally, with a blushing face, she slowly walked up to Martin and handed him the magic circle. Martin subconsciously thanked him, and the girl replied in a voice as thin as a mosquito, "You're welcome."

If the distance was not very close, Martin probably wouldn't have heard it at all. Then, the girl shyly bowed to everyone and hurried out of the living room like a frightened little rabbit.
