The tall tree blocking the road has a crown of about a hundred meters.

Countless aerial roots fell to the ground, forming a small forest.

The buildings within a radius of 100 meters grow together with this giant tree, forming a strange symbiotic relationship that looks extremely beautiful.

Not only in front of them, but also in the distance, they could see many such huge towering trees, which gave the old White Star City a strange beauty.

"Isn't this city only abandoned for 18 years, how can such a huge tree grow......" Han Wei muttered as he walked through the woods.

"When the Heavenly Demons die, their flesh and blood will cause plants to grow faster, and most of the fertile lands in this world are ancient battlefields. Bai Hua explained.

Han Wei was stunned: "The flesh and blood of the Heavenly Demon still has this effect?"

Bai Hua nodded: "If you kill a Heavenly Demon somewhere, the plant growth rate of this land can be increased by half, and if it is a battlefield where thousands of Heavenly Demons die, the plant growth rate can be increased by at least ten times." ”

She pointed to the city in the distance: "Obviously, the old White Star City is an ancient battlefield, and after three thousand years, plants can still grow so fast. ”

Han Wei was puzzled: "Why haven't I heard of a plant group that grows so fast?"

"Because it's so wasteful for such good land to grow naturally into a forest, most of it is used for farming. Bai Hua rarely talked more than usual, and she added, "Moreover, it's just that such forests are rare in the Xu tribe, and you can still see them in some places." ”

There are more and more strange things about the planet.

Han Wei nodded thoughtfully, his mind connecting the various situations he had found in this world.

But he thought about it for a while and then gave up, there were too few clues and it was difficult to connect.

Let's continue to explore, and when there are more clues, we will always figure it out.

They turned a street, and Mastiff Jing exclaimed, "! Look at the University Hall!"

Hearing Mastiff Jing's words, Han Wei and Bai Hua looked in the direction of the university hall.

Where they were, there were still six or seven hundred meters away from the university hall.

However, even from this distance, they could still see an exceptionally large tree standing in the original location of the school.

Even from a few hundred meters away, you can still feel the astonishing scale of the canopy.

The huge canopy of the tree is like an umbrella covering the sky and the sun, and the thick trunk is probably twenty or thirty meters in diameter.

The giant tree stands like a skyscraper of dozens of floors in the original location of the University Hall.

From where Han Wei and the others were, they could only see the giant tree.

The building that was supposed to belong to the university hall is completely gone.

"Such a huge tree...... I'm afraid the university hall has been completely swallowed up. Han Wei's face was ugly.

"We've come here, so let's go and have a look. Bai Hua said.

Han Wei didn't say a word, and walked in the direction of the giant tree.

"It's so big, it's like a giant mushroom. Mastiff Jing sighed.

I walked to the front of the university hall.

Looking through the collapsed wall, you can see that the huge tree occupies the very middle of the school square.

The trunk of a tree about 30 meters in diameter broke through the earth and plunged straight into the sky.

Like a giant's umbrella, it covers the sky.

And Han Wei and the three of them are now standing under this giant umbrella.

"I still have doubts. Han Wei was puzzled, "If all the plants in this city grow so fast, why didn't the old White Star City have these problems when it was still in use before?"

"A normal city is inhabited, and the plants are always taken care of. Bai Hua explained, "Moreover, haven't you noticed that there are very few plants in normal cities?"

Han Wei shook his head: "I've only been to White Star City......"

"You should be glad that this tree grows in the square, otherwise the university hall would have been gone. Bai Hua didn't answer Han Wei's words, but pointed to a building ruin behind the giant tree, "Now the university hall is finally not completely destroyed. ”

Behind the giant tree is a massive building.

This huge building has two main buildings more than ten meters high, boxy and looks solemn and atmospheric.

Between the two main buildings is a promenade, and behind the promenade is another square building, slightly lower.

Eighteen years of abandonment have left most of the building overgrown with plants, with countless vines, branches, and moss dotting the inside and outside of the building.

Fortunately, the main structure of the building was not broken.

However, even so, for eighteen years, the unbridled growth of plants has left the building in a dilapidated state, not to mention the countless small animals that have nested here.

An animal that looked a bit like a deer jumped out of a broken hole in the university hall.

It looked at the erect creatures with wide eyes and curiosity, curiosity in its eyes more than fear, and it was only when Mastiff tried to catch it that it jumped away.

"It's a pity, I thought I could eat grilled mushrooms and barbecue meat at night......" Mastiff Jing smashed his mouth regretfully.

"How did you change from a pit to a foodie...... Han Wei complained helplessly.

"Hey, my dad told me that when you go out, the most important thing is to eat and sleep well, otherwise it will be very hard!" Mastiff Jing patted his armband, "I have dozens of catties of various spices in it, and it's no problem to bake anything you want!"

"The library has arrived. Bai Hua interrupted the words of the two, and the two of them perked up and hurried a few steps to catch up with Bai Hua's footsteps.

Walk through the corridor between the two main buildings of the University Hall and walk to the lower building.

Bai Hua flicked the map in his hand: "This is the library of the University Hall, we are lucky." ”

Han Wei was very surprised: "Yes...... I really didn't expect it. ”

The building still looks very good.

The people who built this building didn't know where to find many Heavenly Demon plates, and they used these Heavenly Demon plates to build the main structure of the building, and then combined these plates in ordinary boulders.

The Great Library thus built was so strong that it was not too damaged during the eighteen years of plant infestation.

The humans on this planet, although not as advanced as the Heavenly Demons.

But this race, which calls itself the "Nuwa people", also has a side that can be proud of itself - they value knowledge and inheritance to the point of being a little paranoid.

The main doors of this library are two heavy wooden doors four or five meters high, which have now decayed and damaged.

The three teenagers cut a hole in one of the doors and entered the large library through the hole.

Han Wei took out a lantern from his armband to act as a light source—the lantern he had asked for from Bayan when he was in Passage Village before, it was made by the Heavenly Demons, and the light was soft and abundant.

As his lantern glowed, there was a fluttering sound of flapping wings coming from the roof of the Great Library—something resembling a bat scattering away.

"It seems that some small animals regard this place as a paradise...... Han Wei took the lantern and shone it around, and walked towards the nearest row of bookshelves, "Let's take a look at the classification first, let's focus on history and practice." ”

These books in the big library have been sitting for more than ten years, and many of them have signs of dampness and adhesion, but they are not so damaged that they cannot be read for more than ten years.

"You said that the officers each had an armband, why didn't anyone take the books here at that time?" asked Mastiff Jing curiously while holding a lantern and looking at these vast books.

Han Wei replied casually: "Because they can't take care of it, those puppets came out too suddenly, and they only had time to transfer important things...... What's the sound?"
