After the old professor finished speaking, he jumped directly onto the skylight, and the whole person seemed to be sucked in. Bai Di followed him and climbed up, then Bai Ling.

Behind the skylight is a huge room, while each of the four walls of the room has a door. The brother and sister came in through one of the doors. It is worth mentioning that in the office, the skylight is obviously open upward, but at this time, in their perception, the door is open vertically. Looking inside the office, it feels very strange.

It's not just the door, it's the whole room. In this room, there are six identical walls, and on each wall are stacked with boxes of various sizes. It seems that every wall here has its own gravitational pull.

The brother and sister stood in the doorway, not knowing where to go.

"It's my private space and it's where I live. The old professor looked at the two children at the door and said, "It's not uncomfortable, is it? These boxes are the spirits of space and time that I have collected from all over the world. Actually, every time I first brought them here, they were piled up on the wall we were standing on. ”

"But what's interesting is that over time, some boxes think that one wall is the right ground, and some boxes think that the other side is real, so they all run to the side they think is the one they think. In fact, in my space, all the faces are walls, and there is no floor. But they always do what they want, and I don't care about them. ”

"What are the spirits of space and the spirits of time?" the two children asked, confused.

"Pure elements can transform spirits. In particular, the spatial and temporal elements are higher than the basic five elements. "Actually, there are two elements that are higher than the element of space and the element of time. That is the element of light and the element of darkness. ”

"Light element and dark element?" the interest of the two children has been fully aroused.

"Why are the light elements and dark elements higher than the time and space elements?" Bai Ling asked, "The space element has an important relationship with the crossing plane. The time element is also already terrifying. ”

The old professor smiled and said, "Son, this is what this plane can't give you. Have you experienced the miracle of the creation of all things? What about the horror of the end of the world? And this is the true power of the light and dark elements. So there are a total of nine elements in this universe. Planets in the lower planes generally have five elements, planets in the middle planes generally have seven elements, and planets in the higher planes only have nine elements. And the gods, all possess the nine elements, which is the foundation. ”

"But if that's the case, isn't it only those in the higher planes who have a chance to become gods? Bai Di asked.

"That's what I'm going to teach you the first lesson. The old professor smiled mysteriously, "It is indeed difficult for people with insufficient elemental ingredients to achieve the body of the nine elements, but you are all elemental holy bodies, so you all have the potential of the other four elements. In this plane, the other four elements cannot be valued and utilized, but if they go to other planes, they may be able to use them well. ”

When the brother and sister heard this, they immediately felt incredible. It turns out that there is such an ability hidden in his body.

The old professor looked at their stunned appearances, and couldn't help but feel a little helpless: "There is nothing surprising about this, it is not uncommon for people who can use higher elements to occasionally appear in the lower planes. Because for each plane, it is not that it is missing any element, but only the amount of more or less. So, in general, a god born from a lower plane will be stronger than a god born from a higher plane. Because they are more capable of energy efficiency. And such gods, even in the divine realm, are all true geniuses. ”

"There is a saying that there is only a line between a madman and a genius. But I can tell you that a madman is still a mortal, and a genius is not a human at all! If you have done something that others have not even thought about, then others will have no way to evaluate it, so they will retreat to the next best thing and judge yourself. But when you think about it, it's out of the way you wanted to be evaluated. ”

"People live only for some thoughts. If, here, when I say the next best thing, it is already the time of the whole world, it no longer matters whether you are a madman or a genius. When the whole world can't bring you what you want, that's when the new world invites you. And our goal is to cross from the lower plane to the higher plane, that is, to raise the nine-colored aura to become a true god, and to make all evaluations and rumors become legends. ”

"That's amazing!" the brother and sister exclaimed.

After listening to the old professor's words, they felt that their hearts had become clearer, and they liked the old professor more and more, and they still had a little admiration.

The old professor looked at the two scrappy children with satisfaction, and said, "Didn't I tell you during the day that I wanted to show you something interesting? ”

This time, when they heard that the old professor was going to show them something, the brother and sister looked at each other and immediately agreed, without thinking about it left or right. Gradually, they truly saw the old professor as their own teacher who taught and solved their doubts.

The old professor opened the door on the opposite wall, and a mellow aura emanated from it. It feels light.

Bai Ling was stunned for a moment and looked into the room.

Huge white tendrils run through every corner of the room, and the ends seem to blend into the walls. If you feel it carefully, you can hear the sound of a slow heartbeat.

"This, it's actually the Elemental God Tree...... Roots!" Bai Ling said in shock, looking at the old professor, "Where did you get it?"

"These are in the depths of the beneath the Magic Temple, which was destroyed in the first place. The old professor glanced at Bai Ling, "I dug it out." ”

Bai Ling was stunned again.

"I've been here ever since I dug it up. It's almost one with my space, it's absorbing my energy to stay alive. The old professor said, "For the Elemental God Tree, even if it lives for hundreds of thousands of years, the exposed part of the ground will not be very large. Usually large are their roots, which can extend tens of kilometers underground. Those people were in a hurry at that time, and naturally it was impossible to eradicate them. Although there is not much energy in this world, it is the only one after all, and it is still growing strong. ”

The old professor paused and said, "But do you know what? If you let it continue to grow for no more than 100,000 years, the energy of this planet will be absorbed by it alone, so that this planet will die early, and the history of your human race will come to an end." ”

Towards the end of the world, Bai Ling and Bai Di both looked at him in disbelief.

"That's what you said, save the world?" Bai Di twitched the corners of his mouth in a strange way, "Then why don't you just destroy it?"

The old professor shook his head lightly and said, "I can't destroy it, it has a special meaning for me." Even if I had to destroy it, it couldn't be that I destroyed it myself. ”
