After thinking about it thoroughly, Chu Tianjiang had to secretly curse his negligence and carelessness, especially carelessness.

Why didn't you think of such a crucial thing before?

As early as 10,000 years ago, underground human civilization found a way to create energy bodies. In the Shadow Empire period, a method for the large-scale production of energy bodies was discovered. That's right, from the very beginning, Chu Tianjiang ignored the energy source, and didn't even think about it at all.

Obviously, the energy source is not just the generation of energy bodies.

In a sense, the energy source does not produce energy bodies at all, but transmits energy bodies in two different micro-universes, or even in two universes of different dimensions.

At the beginning, the intelligent individuals of the great civilization gave the energy source to Chu Tianjiang, obviously hinting at Chu Tianjiang.

Although Luo Jinyong had thought of this a long time ago, and put forward relevant theories, believing that the energy source was the key to breaking through the space barrier, Chu Tianjiang had not thought about it that way, he was not a physicist, even if he heard Luo Jinyong say it, he would not think about it carefully.

In other words, Chu Tianjiang did not find any hints given to him by the wise individuals of the Great Civilization.

The key to the energy source is not to obtain the energy body from it, but to explore another micro-universe through the energy source.

The reason why the invaders came to the front of human beings is related to the energy source, that is, the invaders took the lead in mastering the method of creating energy sources and using energy sources to break through the limitations of space, and used this method to go to other micro-universes, and finally captured and controlled other micro-universes.

Of course, it's certainly not that simple.

Perhaps, in the early days of the invaders' arrival on Earth, the energy source played a crucial role, such as using the energy body provided by the energy source, the invaders created a powerful period, so as to destroy the underground human civilization and transform the human civilization.

If nothing else, it would definitely take a lot of energy for the moon to collapse and form a lunar ring.

All in all, it's the energy source that really matters.

Of course, the energy source created by the invaders is not necessarily the same as the energy source provided by the intelligent individuals of the great civilization, but may be different.

Chu Tianjiang sighed secretly, it shouldn't be too late to realize the importance of the energy source now.

According to Thorlingberg's memories, the Ancestor of Magic was inside the energy source, a special device made of energy bodies to be exact, and it was always asleep. Using the energy body generated by the energy source, the Magic Guild took control of the Northern Continent and established a set of world order with the Magic Guild as the core. Restricted by the powerful field, the mage, and the rest of the world thought that their world was so big.

All of this didn't change until four years ago, after the sudden appearance of the church.

When the powerful field that enveloped the northern continent was destroyed, Sollingberg sounded the alarm and demanded that all mages return to the Tower of the World Realm immediately. It was just after all the magicians had returned that the attack came. In his words, a group of demons attacked the Tower of the World. Of course, that's just his opinion. It was the Church that attacked the Tower of the World, and it was the most powerful modulator in the Church, the Patriarch.

The battle went on fiercely, and no one was spared by the magicians.

Although Sollingberg is a great magician, his "magic" is useless in the face of demons, and other magicians are no exception.

At the last moment, Solingberg retreated into the tomb and used himself to form a confinement ground before the demon entered.

That's how Sorinberg narrowly escaped.

Of course, he also knew that the target of those demons was not the magician and the magic union at all, but the magic ancestor who had been in the tower of the world.

Then came the four-year wait.

Because a large amount of energy bodies were consumed, the energy source was taken away, so Sollinberg could not recover on his own at all, until the arrival of Chu Tianjiang and the condensation of the scattered energy bodies together, he regained consciousness, and through consciousness control, he returned to his original appearance.

"What does the Magic Ancestor look like?"

"It's about the same as us."

"What do you mean?"

Sollingberg shrugged his shoulders. "With a head and hands, a nose and eyes, it's similar to us anyway."

Chu Tianjiang sighed and looked at Iska.

Iska passed on the memories he had obtained from Solrinberg to Chu Tianjiang, giving him a more direct understanding of the specific form of the invaders.

It's really similar to humans, but there are some obvious differences, a bit like elves.

Of course, Chu Tianjiang is not easy to describe what it looks like, no wonder Sorinberg is so embarrassed. The eyes are slightly larger than those of humans, and they have two layers of eyelids, which are consistent with the characteristics of aquatic life. The surface of the body is covered with a moist layer, perhaps not skin, but a protective device similar to the skin, that is, clothing. The hands and feet are relatively short, and they appear to have obvious degenerative features. The body is relatively round, but with protective devices on, perhaps there is a lot of space in it to accommodate life-sustaining substances.

Chu Tianjiang was a little regretful, because all Thorin Borg knew was the appearance of the intruder wearing protective equipment.

In the Magic Guild, the intruder is the ancestor of magic, and obviously no one will touch the intruder's coffin, and they will not know the true face of the intruder.

"How's it going, can I ...... now"

"There's one more question." Chu Tianjiang pressed his hand towards Iskar and said to Sollingberg, "How did you get here in the first place? ”

"This ......"

"Don't lie to me."

Solingberg gritted his teeth and said, "The one who discovered this place was the first Grand Magician. Of course, according to the records of the Magic Guild, he is the guardian of the Magic Ancestor, and thus receives infinite magic from the Magic Ancestor. In fact, he was just a fisherman before he became a great magician. ”

"Fisherman?"

Solimbo nodded. He lives in a fishing village not far from here and makes a living from fishing. One day, he was caught in a whirlpool. When he woke up, he was already here. Curiosity prompted him to touch the bed of the Ancestor of Magic, the thing you were talking about, and something very strange happened. When he woke up again, he had magic and became a great magician. ”

"It's that simple?"

Sorinberg nodded quickly and said, "It's as simple as that, at least that's what I know." ”

Chu Tianjiang frowned and thought for a while, Iska had already told him through his consciousness that Sorinberg was not lying, and that it was indeed the case.

The problem is that there is clearly something that cannot be justified.

Is it just a coincidence?

Obviously it's not that simple!

If it weren't for the coincidence, it was the intruder who brought the first great mage here, and the intruder did so because it obviously needed someone to protect him.

That is, for more than a thousand years, it has been the magicians who will protect the invaders.

The problem arises.

Now that the invaders have chosen Fester, and Fest has also established a church on the Old Continent and begun to carry out the mission arranged by the invaders, why did the invaders hide in the northern continent, create this confinement ground, and create a magic union to protect it?

This obviously doesn't make sense!

The only explanation is that the invaders didn't trust Fest at all.

This point had already been learned by Chu Tianjiang from Feister's thoughts five years ago. After creating Fest, the invaders felt not surprise, but panic, especially after Fest obtained Bagar, and the powerful combat power displayed was even higher than that of the invaders. In other words, the invaders were also afraid of Fest, otherwise they would not have fled here and made a magic guild.

The question is, Fest is loyal to the invaders, so why should the invaders be afraid of him?

Perhaps, it was not Fester that the invaders were afraid of, but humans.

Although Fest is the work of the invaders, he is of human origin, and at least in the time he was made, the invaders used human genetics. That is, in essence, Feist is a man, an almost perfect person. Although it is impossible for a person like him to emerge in natural evolution, sooner or later human beings will enter the stage of self-evolution, and they will be able to produce perfect people through scientific and technological means.

What the invaders are afraid of, it is the perfect one who owns Bagar!

It can be seen that human beings have a strong potential for development, which makes invaders feel afraid and even dare not trust the people they have concocted.

It was also because of this that when the invaders left, they left Fest with very little to do.

To this end, Fest formed the Church, first took control of the Old World, doing everything possible to develop technology without attracting the attention of the invaders. At that time, Feist didn't know that the invaders had left, at least one of them had stayed, and he didn't know if the invaders were spying on him, so he had to keep a low profile, and the church couldn't openly develop technology, or even did the opposite. After accumulating enough strength, Fest began to act, first of all, to conquer the other continents, find the hidden invader, and obtain the power source. After completing this step, Feist will be able to obtain the technological means to break the spatial barrier.

And then what?

Chu Tianjiang was a little puzzled, because according to this inference, Feist was not serving the invaders, but trying to take revenge on the invaders.

Is this possible!?

To know Lu Dao, this is diametrically opposed to Chu Tianjiang's previous judgment of Feister.

"Brother Chu......" Iskar reminded Chu Tianjiang through consciousness.

Seeing Thorlingberg looking at him with blank eyes, Chu Tianjiang smiled and said, "Great Magician, do you know what Lu Dao looks like outside now?" ”

"What does it look like?"

"The Northern Continent is completely finished, the vast majority of the population is dead, there are less than 10,000 survivors, and the enemy is stronger than it was four years ago."

"This ...... It can't be ......"

"I advise you not to go anywhere, it's best for you."

Before Sollinberg could react, Chu Tianjiang made a move. When Chu Tianjiang killed Solrinberg, Iska and Soya were extremely surprised.
