The lightning that was stimulated did indeed have the urge to become a professional immortal. However, the refining of immortal pills wasn't something that could be done overnight. Remembering the countless fortuitous encounters in the novels of the Immortal Hero, as well as the fact that just a single immortal pill was enough to turn the world upside down, Thunderclap knew that this career path was extremely uncertain.

"It seems that we should still put our ideas into the energy storage crystal."

Thunder knew this was an awkward path, but this was the only way to proceed.

Bo Moduo also nodded and said, "That's right. After all, we're new here, and if we're able to find the road to riches soon, it'll be a huge blow to those old monsters who have lived here for thousands or even tens of thousands of years."

Thunder knew that this was something he had no choice but to do, "Forget it, let's return to the Demon World first and then bring out a large number of energy storage crystal before we make our calculations. After all, all sorts of great projects require a certain amount of capital, and what we lack the most is capital. "

"Wait a minute!"

Bo Moduo suddenly saw a restaurant's signboard and immediately set it down: "Dimensional Restaurant is an extremely crazy place. Here, you can eat the food from various major dimensions, and even intelligent race and the others will use it as food. If I remember correctly, Angels and Demons are their signature dish. It is said that those who are able to successfully capture a living Angel or Demon are able to sell them to others, which is much more valuable than directly killing them. "

Thunder was completely stunned.

He followed Bo Moduo's gaze and saw that there was indeed a name for the dishes on the menu, relating to Angels and Demons.

Bo Moduo said: "And this is not only that, I remember that the slave merchants of the plane are also doing this business. If I remember correctly, a demon slave with master level above 1 could be sold, a demon slave with peak level above 1 could be sold, a demon slave with peak level above 1 could be sold, a demon slave with peak level above 10, and a Saints level demon slave could be sold, selling, to 100 source crystal. As for those demons below the Master level, it's said that they won by numbers. It's said that there was a guy who sold all the demons in the entire plane and directly harvested a million source crystal. "

The corners of Thunder's lips curled up when he heard this.

However, he had a nagging feeling that the plane merchants were not idiots. Buying so many Angels and Demons would definitely not be just simply selling them. After all, there was nothing that could consume such a slave all of a sudden.

Thinking of this, Thunder said his conjecture was going to come out.

Bo Moduo laughed: "I know you want to grasp this secret, but this secret is a secret within their industry, it is not something we can casually know. However, in the plane world, there is nothing that source crystal can't buy. Maybe we can give it a try. "

Thunder immediately woke up and asked: "How many source crystal are needed?"

Bo Moduo thought for a while and replied, "There are shops that specialize in selling information in the plane world, maybe we can go and try."

Without saying a word, Thunder took out all of his source crystal s and said: "Bo Moduo, go and try it out. If it doesn't work, we will retreat and obediently sell our demons. As for the other things, we'll think about it when we have enough source crystal. I'll wait here for your news. "

Bo Moduo nodded and left without a word.

As for Thunder, he didn't wait foolishly on the spot and started to wander around.

Very quickly, Bo Moduo brought back the news.

Bo Moduo said: "So that so called trade secret is only their industry secret, it is not very important, I only spent 100 source crystal to buy it."

Thunder did not interrupt, waiting for news from Bo Moduo.

Bo Moduo continued to speak, "The reason why the plane slavers want to make such a big business is not because the gods of many planes lack people and need a large amount of faith foundations, nor is it because the war between planes requires a large amount of cannon fodder. The main reason why they want to buy so many intelligent race s is because they want to raise up the intelligent race s and sell them on the basis of ensuring their own growth.

"Forging source crystal!"

The thunder was deeply shocked.

"Yes, it is to create source crystal!"

Bo Moduo replied firmly. However, his eyes were filled with sorrow and anger.

Thunder trembled as he asked, "How did they do it?"

Bo Moduo replied with a dark and cold face: "The reincarnation pool of the The Immortal World, the rebirth wheel of the cultivation world, the yellow springs of the Underworld, the well of immortality and the well of life of the Elves, the Deity's Lake of the Demons, the pool of redemption of Angels and so on all have similar effects. As for the transformational powers that the plane merchants have grasped, no one knows. "

"Elves, Angels and Demons have mastered such terrifying techniques!"

The thunder was shocked, but more than that, it was filled with joy.

However, the Golden Elves held the Sun Well, the Moon Fairy held the Moon Well, and although the Flower Elves didn't have the Sun Well or the Moon Well, they were the elven tribes that had inherited most of the knowledge from the The Age of Elves. If Thunder were to investigate deeper, he would probably be able to unearth the secrets of the Well of Eternity and the Well of Life.

Since there was already a deal, it would be stupid if Thunder didn't take the initiative to attack.

Thunder didn't waste time with words, he pulled Bo Moduo and started teleporting straight to Grace Mainland.

Thunder and Bo Moduo looked at the Demon World in front of them. Bewildered and darkness was the portrayal of this place, causing them to forget that they were here to capture a demon.

However, in terms of the number of demons, the lowest level submergence was the most. The submergence's reproduction speed was extremely exaggerated, to the point that they were practically the Demon World's goblins, with their population accounting for half of the total population of the Demon World. However, the moment he thought about how hundreds of millions of submergence would represent the number of source crystal, he couldn't help but feel an uncontrollable impulse.

"Bo Moduo, just how old is Demon World?"

Although Thunder was more or less the master of the crystal wall, this was still the first time he came to Demon World. It had to be said that the master of the crystal wall did not pass.

Bo Moduo replied, "The structure of the Demon World is very different from our continent, but they are still a little similar. For example, if the surface of the Grace Mainland was the first level, then the Underground World would be the second level. As for the Abyss Hell, it would also be the Abyss Hell and the ash plain, which were connected to the Abyss Dimension, would be the third level. The first level was the weakest world, and the deeper one went, the more powerful it became. Although I also do not know how many levels there are in the Demon World, but according to the rumors, there are a total of six levels in the Demon World, so we are currently at the first level. "

Thunder also understood.

His ability to accept things was exceptionally outstanding. Even when he heard of the construction of such a strange world, he was not surprised. It was as if he took it for granted.

"Let's go!"

Thunder did not want to waste time, so he tried to understand the knowledge of the Demon World as he walked.

Bo Moduo explained as he walked: "The submergence is a greedy yet timid type of demon, they are the lowest level of beings among demons. Therefore, the first level can be said to be their world. They were like locusts. Every place they went was a disaster. Every place they went, everything that could be digested would be eaten clean without a trace. If not for the fact that the Demon World's dark elements were everywhere and helped the dark plants to grow stronger, this would have long been a desert. "

"Interesting."

Thunder said, "They are indeed very similar to goblins. Greedy and timid Goblins would challenge the powerful Magical Beast for food, which is completely inconsistent with their cowardice. The poor Goblins' reproductive ability is too exaggerated, resulting in them never being able to meet the demand for food, so they are always hungry. "

On submergence's body, the lightning really saw a very deep shadow of a Goblin.

After flying for an unknown amount of time, the instructor had gone dark everywhere, except for the darkness. However, Thunder still knew that this was an endless desert, pitch black. The aura of death in this place was very disturbing.

All along the way, and Thunder had not seen any animals, only some scattered dark plants. There was no sun in the Demon World, the plants here not only relied on the nutrition of the earth, but also the absorption of dark elements.

The drowsy Demon World did not have a starry sky. There was only a drowsy darkness, it was so oppressive that it was almost suffocating.

However, having seen an even more terrifying ash plain, Thunder didn't feel anything. Since he had come to Demon World, it would naturally take some time before he could leave. Moreover, he would also need to find some valuable materials here, and even what Deity's Lake s they were.

"Eh, are those submergence s?"

Thunder stopped in the air. A few hundred meters away, a group of little demons with dark red skin and holding trash weapons that were not much bigger than Dwarf appeared. They were chasing after a group of wild beasts that were running around the dark plains.

"That's right, those are the submergence!"

Hearing Bo Moduo's affirmation, Thunder did not hesitate and immediately flew over. When Thunder saw them, he knew that these submergence s were all below the Advanced Level, but they were not below the Intermediate Level. In the Grace plane, they were considered little experts.

"Oh no, there's an enemy!"

"I hate this kind of energy!"

"No, this taste is very good!"

"The enemies are very strong. If we eat them, we will definitely evolve again!"

When the first submergence began to wake up, immediately after, another submergence began to shout, and many of them looked in the direction of the lightning, their eyes revealing an intoxicated expression.

At this time, all the submergence gave up on chasing after the group of wild beasts and stopped in their tracks. Some of them even ignored the identity of Lei and the others as they flew towards the group without any hesitation, not wanting to share any of their prey with the other submergence.

"Dirty creature!"

Thunder felt that the submergence was very pitiful and disgusting. He lightly patted the head of one of the submergence who was charging at the very front, causing this submergence's head to explode before he could even react.

"As long as we kill these two Angels, we can evolve."

The submergence s were not scared to escape, it completely went against their timid nature, as though they thought that if two of their hundred plus submergence s fought against each other, they would definitely be able to kill the other party.

Honestly speaking, if the submergence were to run away, then it would be even more troublesome for Thunder to chase them down. However, if they went all out together, it would definitely save a lot of time.

BOOM!

With the power of thunder, such a battle was akin to bullying a child. No, it was more like stepping on ants. A group of mid-tier Little Demons, in Thunderclap's eyes, weren't even considered fart.

The lightning did not move at all, and with every movement of the lightning, the submergence continued to slow down at a terrifying speed.

"Run, this Angel is too powerful!"

One of the stronger submergence saw that something was wrong and ran away. But at least he had a sense of loyalty, so he remembered to remind his comrades.

This was also due to the fact that demons and angels were incompatible. Otherwise, how could they have charged at him so brazenly? However, the submergence s did not expect themselves to run into a large iron plate. Originally, there were close to a hundred submergence s that were killed in one fell swoop, and the other side looked like they were playing a game.

"Is it that easy?"

Lei sneered. The reason why he was so interested was because he wanted to maximize the benefits.

With a wave of his hand, more than ten bodies were completely split apart.

"Mercy, my lord!" I can be the guide here! "
