It's possible to practice magic this way, right?

Just as Christine said, this building is really tall. It should be where the ruler of this city lives or works. Along the way, it can be clearly seen that the houses in the middle are of higher quality.

It seems that this is the case regardless of race.

Lin Li looked at the building in front of him and asked Christine, "What happened when you went in?"

"There were many rooms inside. I found a box in one of the rooms. There was a scroll inside the box. Later, I encountered a metal puppet behind a door. The metal puppet was very powerful. I was no match for it at all. I was injured in just a few moves. I had no choice but to use the scroll directly."

"Luckily, it was an aggressive one and saved my life. At that time, I didn't have much food left and was injured. I was afraid there might be more danger, so I didn't dare to stay in here and ran away. Fortunately, the way back was smooth."

"How dare you use this scroll without even knowing what it is?"

"You're going to die if you don't use it, so why would you care so much at that time?"

It's true that fools have good luck, he can survive this.

Lin Li collected Gaina and said, "Let's go in."

The first thing they saw after entering was a hall. Lin Li released a lighting ball so that the two of them could see more clearly.

The first floor is very high. Judging from the buildings outside, this race should be shorter than humans. But the height of this hall is at least eight or nine meters.

This hall was very large, with huge carved murals on both walls. Lin Li and Christine moved closer and adjusted the lighting orb upwards to see the murals more clearly.

Lin Li discovered that these murals are continuous narrative murals.

There were many little people on the first painting, each with a horn on its head. They were living a peaceful life. There was no sun in the sky, but a scepter instead. Lin Li guessed that it meant that they were living a stable life under the protection of the scepter.

The second painting showed many strange-looking monsters. The little people looked at the monsters with terrified expressions.

The third painting showed corpses everywhere, and the living place had been destroyed. There were flames burning everywhere, and the little people were desperately running away. There was a portal where they were running away.

The fourth painting shows the sun shining on a desolate land, and the little people seem to be melting under the sun.

The next mural is on the opposite wall. The fifth is about migration, the sixth is about excavation and construction, and the seventh is a person standing next to a glowing plant with a book in his hand.

Lin Li looked carefully and found that the book should be the one in his hand. The last painting showed a man standing on a high platform, holding a scepter in one hand and a book in the other. Countless people were kneeling down to him. The scepter was the one in the first painting.

There were words underneath each mural, but Lin Li didn't recognize them.

Although he didn't know what was written on the mural, he understood the general meaning of it. Lin Li recorded it with a photo stone.

Lin Li said that this is a very old-fashioned plot. So this race should have migrated from another world. Their original world was invaded. This race should not be adapted to the strong sunlight, so they hid underground.

Lin Li thought that if their world was occupied by the demons from the abyss, it might end the same way. These people could still find a place to stay in this world. If this world was occupied by demons, there was no way out.

Lin Li asked, "Didn't you see these murals the last time you came here?"

Christine rolled her eyes at Lin Li and said, "What am I looking at? These murals are so high, can I see them clearly with a torch?"

"Besides, these murals can't be removed, so they are worthless. What's the point of looking at them?"

"You don't understand this. Do you see the book and the scepter?"

"From the murals, we can tell that the most valuable things in this race are the scepter and this book."

As he spoke, Lin Li patted the book floating beside him.

"And from the production of this book and the glowing plants outside, we can tell that this race's magic level is also very high."

"It shouldn't be lower than the level of our world. Especially the technology used in this book, it's simply incredible."

"So if the monsters that invaded their world come to invade us, we may not be able to defeat them."

"And the fact that those villains can run to our world means that we are not far from their original world. And their world has been occupied by monsters."

Christine waved her hands and said, "Who are you trying to scare? These people have been away from our world for who knows how many years. If those monsters were going to come, they would have come a long time ago. Why wait until now?"

"Besides, we humans only have a lifespan of a few years. I'll be at most 100 years old. As long as those monsters don't come before I die, it'll be fine."

"Who said you can only live to be 100? If nothing unexpected happens, you can live to at least 150."

"Who are you kidding? 150? How is that possible?"

"Trust me, because you've been struck by lightning."

"What's the meaning."

"literal meaning."

Lin Li didn't want to explain, so he changed the subject.

"The murals don't explain why they suddenly disappeared, and this book, which should be very important, was not taken away."

"Judging from the situation in this city, they should have moved away. But if they did, there's no reason why they would have left this book behind."

Kristen said to Lin Li, "Why think so much? If it's taken away, you'll be gone, right?"

"Okay, that's right, think about what to do."

Behind the hall were the many rooms that Christine had mentioned. It felt a bit like a hotel. Although Christine had searched all the rooms on this floor, Lin Li still searched them again carefully.

After a whole circle, nothing useful was found.

"It seems that you are pretty clean when searching for things."

"Clean at all, I only found one scroll on this floor."

Christine pointed to a doorway, and it was behind this door that I encountered the metal golem.

Now the door is open and the stairs leading to the upper floor can be seen from the outside.

He didn't know what was going on up there, so Lin Li released his magic eye and wanted to go up there to have a look. But as soon as the magic eye went up there, it lost contact.

Lin Li frowned. He used the Earth Sense. But he could only sense the first layer. Lin Li didn't believe it, so he used the Wind Sense. But the result was the same as the Earth Sense.

"Can't I get to the second floor without taking the stairs? Humph."

"Let's go in from the outside."

Lin Li ran out with Christine and looked up at the wall outside.

The two walked around but didn't see a window. Good fellow. Although you don't need sunlight, don't you also need ventilation?

Lin Li flew to the height of the 2nd floor and fired a lightning sword energy at the wall.

What Lin Li didn't expect was that the wall was completely intact, and the sword energy came back the same way it went.

Fortunately, Lin Li reacted quickly and turned around to avoid it.

Lin Li fell to the ground and said in surprise: "Damn, the protective magic circle has not disappeared yet, and it is a rebound type."

"That's cruel enough, let's go back and take the stairs."

Lin Li asked, "Was the door of this tall building open when you came here last time?"

"Yes."

"Then you are very lucky."
