The reason why Zhao Hai wanted to obtain this technique so quickly was for the sake of his Dharma artifacts. With this technique, he could create a subspace in all his Dharma artifacts and build the yin-yang Lightning Pool in the subspace. This way, his yin-yang Lightning Pool would be larger and could provide more energy for his Dharma artifacts.
Although Zhao Hai wanted to obtain this technology immediately, it was impossible. Even the universal analyzer could not analyze it because his level was not high enough.
This made Zhao Hai understand that he was still far from being strong enough. If he wanted to increase his strength, he would have to increase the level of his dimension.
But the problem was that it wasn't easy for him to upgrade the space now. What was the situation with the space now? Items with Heaven Earth spiritual roots could only upgrade the space by a dozen levels. It was too difficult for him to upgrade the space with ordinary items.
