I am the son of the Dragon God in Douluo Continent.

Over the next few days, Xu Xingyu guided Gu Qiuxi on how to unleash skills without relying on soul rings, while also observing the differences in the energy and soul power of his body now that he was recharging.

In Xu Xingyu's view, the two are about the same in terms of energy level, but this energy seems to be linked to elemental power, and every time it is used, it inevitably brings elemental power with it.

Gu Qiuxi also deeply felt this. Originally, when she transformed into human form, she used her own Golden Dragon bloodline and the Golden Dragon King Divine Core given to her by Xu Xingyu as a guide, so that her martial soul was ostensibly a Golden Dragon, but in reality a Golden Dragon King.

This action certainly granted Gu Qiuxi greater power, but it also caused her to lose the attributes of ultimate fire and ultimate light that she possessed during her Three-Eyed Golden Ni period.

Here, Gu Qiuxi discovered that she could once again use her ultimate fire and ultimate light abilities. However, it was strange that her ultimate fire seemed unusual, since she did not remember that her flames could switch between gold and black.

Having seen a lot about this before, Xu Xingyu immediately recognized that the golden one was the ultimate Yang fire, while the black one was the ultimate Yin fire.

Normally, unless there is an innate attribute problem, few people can use the Yin and Yang of an element separately. In most cases, the attribute is the result of the fusion of Yin and Yang.

Fortunately, Xu Xingyu already possessed this ability, but Gu Qiuxi had never had such experience before, thus it could be concluded that this was due to the unique nature of this plane itself.

As expected, the black and white colors of the crown they released represented the so-called balance of yin and yang.

Fortunately, this will not have any negative impact on them, because they can still use the flames that are not yet separated from Yin and Yang, and it will not affect their cultivation.

However, this cultivation system gave Xu Xingyu an increasingly familiar feeling. He was certain that he had read a novel about this plane when he was on Blue Star in his previous life, but because it had been so long, he could no longer remember which one it was.

So, in order to determine which world they were in, in addition to teaching Gu Qiuxi to master her soul skills, Xu Xingyu also took the time to check their current location.

You don't know the result until you check. The more you check, the more your doubts are not resolved.

According to his observation, they were currently on an island that appeared to be located in the middle of two continents and was enveloped by a lightning prison released by a so-called god-level powerhouse, making it impossible for any creature to leave the island.

The entire island is divided into eighteen layers.

The first to thirteenth layers are concentric circles, each circle progressing inwards. The outermost layer is the largest, decreasing in size towards the center. Each layer presents a different scene. The first layer is an endless forest; the second is a lush, undulating grassland; the third is almost entirely rolling hills; the fourth is relatively flat, but dotted with towering boulders; the fifth is a wetland with numerous small hills; the sixth consists of peaks five or six hundred meters high; the seventh is peaks over a thousand meters high; the eighth consists of three even taller, snow-capped peaks, within which lies a vast basin; the terrain becomes more complex from the ninth to the thirteenth layers, no longer a single type of landform, but a patchwork of lakes, forests, mountains, hills, swamps, and other complex features. The twelfth layer is dominated by a large lake, surrounded mostly by forests.

The fourteenth to eighteenth levels consist of five large mountains arranged in a cross shape, side by side without any particular order. These five mountains are each a different color. The mountain in the center of the cross is yellow, the one to the north is black, the one to the south is red, the one to the west is white, and the one to the east is cyan.

Although Xu Xingyu wanted to explore the island further, she could clearly sense that there was a demigod-level expert in each of the five mountains.

If he were alone, it would be fine. Even if he couldn't defeat these powerful individuals, he would still be able to leave calmly. But if he also had to protect Gu Qiuxi in the middle, then the risk would be much higher.

Of course, what intrigued Xu Xingyu the most was this Thunder Prison that enveloped the entire structure. Just as mentioned before, this Thunder Prison was probably created by a god-level expert. According to Xu Xingyu's estimation, it was created by a peak level two god or higher.

This Thunder Prison's containment of the island isn't simply a matter of using lightning to isolate it; it's more like a spatial seal. Because of this Thunder Prison, the island appears to be located at the very center of two continents, but in reality, the space it inhabits is isolated from both continents.

Therefore, you could even say that this is a secret space opened up at the junction of two continents, similar to a small world, only not as large.

Although there are traces of humans on the island, judging from the positions they have established, they seem to have only been on the island for a short time.

The majority of the island's territory is still ruled by various kinds of beasts, which are far stronger than normally grown beasts due to the special nature of this space.

This made Xu Xingyu feel even more strongly that she should know the name of this world and should have read the corresponding works, but considering that she still hasn't remembered it, she probably only glanced at it.

However, Xu Xingyu didn't dwell on this matter. Since he couldn't remember, he decided not to think about it for now, believing that he would remember it sooner or later.

As for what crises might arise that he can't handle? Please, he's a being with a god-level spirit and a god-level body. Even if a true god-level powerhouse descends, he can hold out for a while. Besides, apart from that bastard Tang San, what god would descend to the mortal realm to cause trouble for someone?

Xu Xingyu believed that her luck wouldn't be so bad as to encounter another shameless god like Tang San or a plane invader like the Abyss Saint King, since such beings were rare even among gods.

Just then, Gu Qiuxi's exclamation interrupted his thoughts: "Brother Xingyu, hurry up and do this!!!"

"What happened to Qiu'er?" Xu Xingyu asked in confusion. Theoretically, there shouldn't be any problems. You should know that Xu Xingyu had set up a barrier in this area in advance, and under normal circumstances, no human or beast could enter without permission.

However, the direction she pointed in next shocked him greatly. She pointed to the spot where his practice had melted, where there was a huge ice pillar. What shocked Xu Xingyu was that there was actually a person inside that ice pillar!
