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

The entrance was actually inside a tree hole. There were a lot of vines hanging from the tree, covering the hole. If Christine hadn't said it, Lin Li might not have discovered that there was a hole here.

Although Christine doesn't seem to be very smart, this may be the case that simpletons have good fortune.

After entering the tree hole, there is a downward passage. Not long after walking, the passage becomes wider and wider.

This passage is not completely dark. There are glowing plants everywhere, which is very beautiful and brings a faint light to the passage.

Although the light is weak, there are enough plants like this, so the visibility distance is much better than the misty forest above.

Lin Li and the others continued walking downwards, and after walking for a while, a huge space suddenly appeared in front of them.

When Lin Li stood at the exit of the passage, he was completely shocked.

There was actually an abandoned underground city inside. And it was huge.

It was still a little dark inside the passage, but it was very bright in this abandoned city.

Lin Li walked into the city. Everywhere he could see a plant that was three or four meters tall. This plant had only a few large leaves. The leaves emitted a faint light. On both sides of the road were rows of street lamps, no, they should be called plants that looked like street lamps. Because there was a large glowing lump on the top of the tree. It illuminated the surroundings of the road very brightly.

Lin Li couldn't help but sigh: "These plants are so magical and very beautiful."

"Yeah, I think so too. Although most of the houses have collapsed, these luminous plants have not received much damage. The most amazing thing is that they can still remain active."

"The last time I came here, I was thinking if I could dig some up and grow them myself. Maybe I could sell them for a good price. Unfortunately, I didn't have the space equipment last time, and the plants were too big."

"Just dig it up? How did you come up with that idea? If you can find the seeds, maybe you can plant them outside. But I don't think they will survive. The environment difference is too big."

Lin Li looked around and found that the houses were shorter than normal human buildings. They should be the habitats of other species. Lin Li could go in and take a look even if he lowered his head.

However, after checking several relatively intact houses, Lin Li shook his head helplessly. It's not that nothing was left. It's just that the time interval was too long, and most of the things were already dilapidated, and many of them couldn't even be seen in their original appearance.

"Where did you find the Mithril last time?"

"In the center of the city, there is a very beautiful and tall house. I found it there. I also found a scroll, which I used to kill the metal puppet."

Lin Li looked towards the middle. Although there were "street lights", Lin Li still didn't see the tall house. It seemed that there was still some distance.

"Should we go straight over there? Or should we search here first?"

"Is this place dangerous?"

"I encountered the metal puppet in the central house, and I didn't encounter any danger in other places."

"Forget it, let's just search slowly as we go. There's no one else here anyway, so there's no need to rush. Maybe we can find something else useful."

Dreams are full, but reality is skinny. No, there is nothing left. I walked for a while and checked almost every house on both sides, but there was nothing useful left.

Maybe there were some before, but I don't know how long it has been. Nothing can survive the knife of time without special preservation methods. This also further illustrates the magic of those lighting trees.

"It seems that these ordinary houses are unlikely to contain anything valuable."

Lin Li thought about it and began to chant the magic eye spell. Since he was promoted to Legend, his mental strength has increased, and the skills of other departments have also been raised by one level. Now he can cast level 4 magic. Lin Li thinks that if he has the corresponding auxiliary equipment, he should be able to cast level 5.

Lin Li summoned four magic eyes in succession and flew in four different directions. His purpose was to find some buildings that looked different, and perhaps he could find something in these places.

Soon they found a different building. Lin Li looked around and saw that the road was not crowded, so he let Gaina out and called Christine to go over together.

The building was a square room that covered a large area. When they walked in, they saw rows of bookshelves with many books on them, but they turned to ashes as soon as they touched them.

Lin Li sighed.

“This should be a library. It would be great if it could be preserved.”

"Let's look for it. Maybe there's something left."

The library had three floors and the building itself was quite solid, with no part of it collapsing. The two of them, along with Gaina, began searching inside.

After a round, they didn't find anything useful. Just as they were about to leave, Christine suddenly asked, "Do you think there is an underground floor here?"

This sentence reminded Lin Li. This place is already an underground city. Isn't it natural to build further down?

So Lin Li quickly released an earth perception, and found that there was indeed another underground floor.

He turned to look at Kristen and said to her with a smile, "I didn't realize you could be so smart. You actually guessed it right."

"It's obviously you who's stupid. Isn't it normal for a library to be built underground? Our Lion Kingdom's library has an underground section."

"Building an underground part of the library? If there is a fire, it will be a disaster. All the people down there will die, and no one will be able to escape. I am stupid, but it is obviously your kingdom's architect who has no sense of safety."

Lin Li retorted, then used earth magic to open a hole in the ground and jumped to the next level.

There were no lighting plants below, so Lin Li released a lighting ball to illuminate the ground. Christine and Gaina also jumped down.

Lin Li discovered that the place below was not a library. And it was not public, because the exit from above was hidden. It should have been protected by a formation before, but it has been too long and has become ineffective, otherwise Lin Li would not have been able to break through the ground with just one magic.

There was only one hall below. There were exhibition stands in it. It was more like a museum. There was a cover. But the cover was mostly empty. The things that were there had not decayed. All that could be seen were some weapons and armor, and some things whose uses were unknown.

At this time, Lin Li noticed a glimmer of magic light ahead. Christine also saw it, and they both became excited and ran over quickly.

I saw a magic circle inside a cover, which was still emitting a faint light, as if it would go out at any time, and there was a thick book inside.

Christine was so excited that she immediately tried to open the cover. The moment her hand touched the cover, a ray of light quickly lit up. Lin Li reacted quickly and immediately pulled Christine back a step. A wall of earth quickly rose from the place where they were standing. Then, just when Lin Li was about to stack up his defense skills, the ray of light quickly went out. The fluctuations of the elements also disappeared immediately.

Lin Li breathed a sigh of relief, then scolded Christine, "You are so reckless that you didn't even notice such an obvious magic trap. Fortunately, it has been a long time and is on the verge of losing its effect. Otherwise, I might have been killed by you."
