After the unicorn baby left, Lan Ziliang took everyone back to the mercenary castle.

This journey took more than half a month, encountered some terrible things, and some awkward things, but more importantly, everyone supported and trusted each other. Along the way, they have become the most ironclad partners.

Lan Ziliang simply did it to the end, and helped the children sell all the ginseng in exchange for a lot of money. Looking at the smiling faces of the children, Lan Ziliang's task can be regarded as over.

After Lan Ziliang left, the children, you look at me, I look at you, and they all smiled helplessly. Before coming here, who would have thought that their experience would be so thrilling, funny, and a little funny. Lan Ziliang is a tyrannical person, but he is particularly protective of his shortcomings, and he doesn't feel so annoying.

The children emerge from the mercenary castle and return to the Persian Junior Academy of Magic. During this period of time, they have been training outside, and they have to run a lot of roads almost every day, and compared with sitting and practicing in school, their physical fitness has been greatly improved. This time, it took them less than nine days to come back.

As soon as they returned to the Persian Junior Academy of Magic, everyone felt physically and mentally exhausted. At this time, their eyes were drawn to a strange old man at the entrance of the academy.

Judging from the old man's face, he was already very old, a few sparse hairs still remained on his head, and his beard was white, mostly white. But judging from his leisurely demeanor and the warm red glow emanating from his face, he didn't look at all like what an old man should be. He wore a wide gray robe, which was also very similar to the clothing style of the last century.

He lay leisurely on a large mat at the entrance of the academy basking in the sun, smiling and waving his hand to everyone, pointing at Bai Ling and Bai Di.

"Brother, he seems to have called us over. Bai Ling touched Bai Di and said.

Bai Di nodded and said to his partners: "That person called us over, you go back and rest first." ”

The rest of the people saw it too, and nodded, they were indeed exhausted, and went back to the academy.

Bai Di took Bai Ling's little hand, walked to the white-bearded old man, and asked, "May I ask the old man, is there anything wrong with coming to us?"

"Well, two cute little ones. The old man smiled and stroked his beard, "You two are very interesting, would you like to come to me to see something more interesting?"

Bai Ling and Bai Di glanced at each other, but neither immediately answered him.

The old man scratched his head, which still had a few hairs left, and said, "Let me introduce myself, I also live in the Persian Junior Academy of Magic, I taught in the academy in the last century, and now I am too old to keep up with the changes of the times. So you don't know me, everyone else calls me the old professor, so do you. ”

Seeing that the two of them did not answer, the old professor continued: "Bai Ling, do you want to know how useful your seed is? I can help you." And you, Bai Di, your fire elemental abilities are second to none. What's more, you both have the legendary Elemental Reliqué, and you are still a brother and sister. ”

When Bai Ling and Bai Di heard this, they looked at the old professor in shock.

"What exactly does the Elemental Holy Body mean, and why can't we find a definition in the book?" Bai Ling asked.

The old professor replied with a smile, "The innate magic fit is determined by a person's physique and soul. Ordinary people, both soul and physique are ordinary. And those who can become magicians have more or less certain advantages in soul or physique. ”

"But what is the Elemental Sacred Body, and why does the word Elemental Sacred Body appear?" the old professor paused, his light gray eyes looking at them calmly, "Have you ever heard of the Elemental Divine Tree?"

Bai Ling looked at the old professor with a ruddy face in surprise, but Bai Di looked at her in surprise.

"Looks like you know. The old professor's smile became even stronger, "Bai Ling, what you have in your pocket is the seed of an elemental divine tree, right?" ”

"Yes, it was given to me by the Elemental Tree as a reward for completing my special quest to find it. Bai Ling nodded.

"Okay, now that you all know. Then I'll make it a little easier. The old professor said, "Of course, the Elemental Divine Tree can't come out of thin air. Like the Colorful Unicorns, they are all races that have a close relationship with the gods. With the power of the gods, it is natural that there will be many creatures who want to be vassals by their side. But with the pride of the gods, they would hardly accept the second place except for the most powerful vassals. Because they are the only world number one in their own plane. ”

"In the universe, there are actually countless planes. The reason why it is said that there are countless ones, among which there are hundreds of millions of basic planes. And God can also create planes, called the plane of divine creation, and the number of such planes is innumerable. Compared with the basic plane, the Divine Creation Plane more or less stores some of God's mental power in it. These telekinesis guide those in it to accomplish God's tasks, or for some reason train them to be people with some function in their own planes, some of which are created planes or even prisons for demons. You see, God, is omnipotent. ”

God, however, is limited by the rules. And where do the rules of God come from? The King of God is called the Lord of Heaven. Among the gods, a great god-king presides over the testimonies of all planes, and this testimony is what the elements build and connect. And the Elemental Divine Tree is a vassal race of this great god king. However, it is not so much a vassal race of the god-king as it is a part of the god-king. Legend has it that the seed of the first Elemental Divine Tree was split from the God King's own Neidan and planted on the ground. ”

"And what I want to tell you is that your Elemental Eucharist has little to do with the energy of this world itself. The old professor paused, waited for the two children to stabilize their emotions, and continued, "The plane we live in has grown up to now, the age is still very young, and the energy accumulated is not enough, although it has spent an incomparably long time, but the time it can still live, relatively like the ratio of the age of the unicorn baby and the colorful unicorn beast king, the death of a plane is enough to make the planet that lives in it change many times." ”

"Hey, I accidentally said something wrong. Let me tell you where your Elemental Eucharist came from. The old professor said, pointing to Bai Ling's pocket, "It's the Elemental God Tree." To be precise, it's the Elemental Tree in the Magic Temple. ”

"Legend has it that Azarik, the ancestor of magic, performed countless miracles in his lifetime and left behind countless treasures after his death. And in my opinion, the most precious thing is the ethereal space that was discovered, and the only elemental divine tree he left in this world. With the ability to obtain a seed from the Divine Tree of the God King, it is no wonder that he dares to claim the title of the Ancestor of Magic. ”

"That means that the Ancestor of Magic also planted the seeds, right?" Bai Ling asked in surprise.

The old professor smiled and said, "What, do you think you should plant it too?"
