The first heir novel (Master Yu Who Smokes)
Chapter 3630

Joe took a lot of effort to calm down the princess.

Upon his firm request, the princess agreed to stay next door to Stefan.

Joe finally found time to rest quietly.

After the princess left, Joe almost passed out on the bed instantly. He did not even think of doing anything with the princess.

After all, he was a married man, so he had no feelings for the princess. To be precise, he did not have romantic feelings for her.

Joe fell asleep just like that. When he opened his eyes again, it was already the next day.

Sleep was undoubtedly the best way for human beings to recover. Joe finally felt that his energy was full again.

To his surprise, the system of the ruined city issued an alarm at this time.

"System warning, if the driving energy can't be found within 24 hours, the ruined city will fall into a deep sleep again."

When Joe re-entered the hall and sat on the throne, he heard this system prompt.

Joe frowned. It was not that easy for him to own this ruined city, after all.

At the very least, he had to replace the resources to drive this ruined city.

Joe tapped the throne lightly with his fingers while trying to figure out what power could drive this ruined city.

At this moment, Joe suddenly received a system prompt.

"Mayor, the princess is requesting to see you. Do you agree?"

When he saw the mention of the princess, Joe suddenly thought of the professor and naturally thought of the mine he had been to before.

If he could make use of the power of that mine, it should not be too difficult to drive the city.

With that thought in mind, Joe started asking the system.

"Does the ruined city have the ability to excavate mines?"

Subsequently, the system gave an accurate answer.

As long as Joe could bring the core of the city to the mine's location, the city core could directly absorb the power there.

After getting this reply, Joe immediately beamed with joy. Without further ado, Joe quickly found the core area under the system's direction, and the core of the ruined city was exposed in front of his eyes. Joe saw many magic circles in front of him, and his heart sank slightly.

How could he replace the so-called core in this mess?

Crack!

There was a sudden noise, and a colorful energy stone appeared in front of Joe's eyes.

In fact, the energy stone was not colorful. It was the intricate magic circles drawn on it.

Joe picked up the energy stone carefully. When the energy stone touched Joe's body, a ray of light suddenly appeared.

This energy stone turned into a ring on Joe's finger.

Seeing this scene, Joe narrowed his eyes and smiled.

He had to admit that the things left behind by the mighty being were exquisite. Even the core of the city could be turned into a ring so easily.
