Three days later, in the morning, the orange-red morning sun crossed the Mad Hat Mountains to the east and shone on the plain of the two rivers. The water system of the Lianghe Plain is well developed, and the air is clean and humid in the morning, and many birds get up early in the morning to forage for food, looking for grass piles with many insects to have a full meal.

At this time, the slave prison built on the grassland had been razed to the ground by Lin Yu's earth splitting magic two days ago. Early this morning, all the people on the Lianghe Plain gathered here. Among these people, there were more than 700 subhumans who had traveled a long way with Lin Yu, nearly 2,000 subhumans who were imprisoned here, and more than 1,000 dwarves.

The sub-people and dwarves who had been locked up in it looked at this sinful concentration camp at this time, and all kinds of emotions were mixed, including anger, resentment, and sadness.

Three days ago, the slaves who had been locked up inside were all freed, and when they were rescued, they couldn't believe it was true.

Although Lin Yu and the three of them had been fighting with those slave owners in prison, the noise they made was also very loud. But the imprisoned slaves were in no mood to pay attention to the outside world, because they had long lost hope in freedom.

But when Lin Yu came, they didn't give these slaves false hope, but directly gave the slaves freedom.

Even at this moment, there are still many sub-people and dwarves who think that these things are unrealistic, and their originally ill-fated selves have freedom for a while, and many people are at a loss, most of their faces are covered with tears, and they don't know whether they are tears of joy or tears of embarrassment.

However, all this is finally in the past, and the future is the most important, although everyone is still facing a lot of problems, but these problems will always be solved, because there is Lord Lin Yu leading them.

The dense crowd spontaneously formed a circle, and they surrounded a nine-year-old boy in the very center of the circle.

At this time, Lin Yu was standing on a soft ground, this place was the center of the previous prison, the day before yesterday, Lin Yu used many times of earth cracking magic to shake all the things on the ground of this prison.

Then whether it was white bones or rubble, or all kinds of rotting corpses, and scavenging animals, Lin Yu buried them all in the soil, and let them return to dust, and the earth to the earth.

At this time, Lin Yu took a palm-sized tree seed and slowly buried it in the soil.

"Is that okay?" Lin Yu asked Lan Xue'er, who was floating beside him, as he buried the tree species shallowly in the soil.

Lan Xue'er was barefoot, wearing a green dress, her little arms and legs were all exposed, and she was very cute. She confirmed that the tree species did touch the land, and said, "As long as it touches the land, I will use magic to spawn it directly!"

"Just one tree species can turn this place into a small castle?" Lin Yu asked in disbelief.

Lan Xue'er said with some pride: "Of course, the architectural magic of our elven clan is the best!"

Three days ago, although everyone was immersed in the joy of freedom, there were many problems that followed. For example, the most important issue of accommodation, how to accommodate the additional 3,000 people?

Originally, the more than 700 people who were with Lin Yu still had tents to live in, but now that there are more than 3,000 people, it is impossible to live in tents.

Of course, it is easy to build a house because of the presence of dwarves, but even if you want to build a house, it is not something that can be built in a while.

Fortunately, Lan Xue'er, the elven race, thought of a way, she took out a tree seed, according to her, this is the seed of the tree of life, which can be used to build a tree castle composed of large trees, which should basically be able to live for so many people temporarily.

As for why we waited until today to start using tree seeds, it was because we had to choose a good location on the plain, but in the end, everyone found that the location of this prison was the best.

This place is located in the upper reaches of the river, near the northeast of the plain, and some further east is the Mad Hat Mountains, which is a natural barrier, and this place is the most suitable place to develop if you want to build a town in the future.

As she spoke, Lan Xue'er floated in front of the tree seed, slowly chanting a spell in her mouth, only to see that the tree that was originally only the size of a palm was rapidly taking root and then germinating under the urging of her spell, and what was even more exaggerated was that this tree species was growing taller and growing at a speed visible to the naked eye!

The trunk of the tree quickly rose high, and then immediately flourished, and after Lan Xue'er's incantation was chanted for almost a quarter of an hour, a large tree in the sky quickly grew.

"Whew!" Lan Xue'er breathed a sigh of relief, it took her a lot of mental power to grow taller for this tree, but the elves loved trees the most, so she was still very happy when she saw the lush trees.

"Give me a potion of life. Lan Xue'er stretched out her hand to Lin Yu, who casually handed a bottle of life potion to the white and chubby hand without asking why.

"Originally, if this tree species wanted to build a city tree fort quickly, it would require two hundred fourth-order spirits or more to cast spells at the same time. Lan Xue'er explained, "Because it requires an elven mage to drive a lot of wood attribute magic to promote the growth of tree species. ”

"However, with this life potion...... Lan Xue'er opened the cap of the life potion, and suddenly a powerful breath of life came to her face, when Lin Yu used the life potion to save the big black bear, she found the breath of life contained in this potion, and if she used this potion to give birth at this time, she should be able to have the same effect.

Then, Lan Xue'er dripped the life potion drop by drop under the root of the tree, only to see that the big tree that had stopped began to grow wildly again.

First a circular wall was formed by long branches, and then the wall grew higher and higher, until it was three meters high.

Then, the tree continued to grow, and the branches and leaves continued to grow, this time creating a second story made entirely of tree trunks, followed by a third and a fourth floor.

At this time, a four-story circular tree castle has begun to take shape, and then Lan Xue'er continued to drip life potions, so that the branches and leaves of the tree of life continued to grow, until the leaves and branches capped the tree fort, made a rain layer, and at the same time used branches and leaves to make a tree wall to block the wind, at this time, Lan Xue'er stopped the drip irrigation of life potion. At this time, only one-fifth of a vial of life potion remained.

"Alright, it's finally done!" Lan Xue'er clapped her little hands, then looked back at the stunned crowd, and said proudly, "How about it, our elven clan's magic is amazing!"
