"What is the Soul Pillar?" Gosling and the scholar who were guarding the side looked at each other, none of them knew what Xi Yunyun meant by these three words.

Xi Yunyun took the towel handed by Wei Qi to wipe away the blood stains on the corner of his mouth, took a deep breath and said, "The memory fragments I found show that one of the ways to realize the soul refining array is to borrow the power of soul crystals from the soul realm. You all know about the Abyss of Nothingness, right?"

The scholars took out the materials and looked through them, then nodded. It's not because they're old and have poor memory, but the Abyss of Nothingness and the Sea of Soul Stars are the realm of the dead, and for living magicians, they are forbidden knowledge. Only a soul mage with the Apocalypse Soul Seal can remember the relevant information, and even if others hear about it from Xi Yunyun, they will quickly and automatically erase the relevant memories.

So the scholars had to record everything, and then use spells to keep the contents from being erased, and read them when they wanted to understand.

Xi Yunyun thought that although this method was very pedantic, it was still useful, and then explained: "To put it simply, in addition to using the Soul Refining Array, you also need to use the Soul Secret Array that connects to the Abyss of Nothingness, and borrow the power of the Soul Crystal from the Soul Star Sea. But in this way, a large amount of mana in the sea of soul stars will be sucked away, causing adverse effects, so it is forbidden.

Unless, at the same time, use the 'Soul Pillar' formation. That is, it is a substitute for artificially creating soul crystals to support the mana balance of the Soul Star Sea.

I guess there will be the same problem on the other side of the demon, and you need to borrow the power of the black soul crystal in the void sand to complete the plan of the artificial demon soldiers. ”

"And how exactly is this soul pillar going to be made?"

"The method is very simple," Xi Yunyun looked at Gosling with a firm and clear gaze, and smiled slightly, "As long as I strip off the Apocalypse Soul Seal and stay in the Soul Star Sea, I can play the role of a soul pillar." ”

Just when everyone in the alliance was rejoicing, the eyes of Xi Yunyun, who were looking at Xi Yunyun from afar, sank, and the chill in his eyes was even worse. He knew what Xi Yunyun's eyes, this slightly pale smile expression, he was too familiar with her, too caring, and studied the meaning of her every expression. Her expression was a determination to sacrifice herself.

Lu Tian didn't want Xi Yunyun to sacrifice himself, he could sacrifice for her, but she couldn't. He couldn't bear to exchange Xi Yunyun's sacrifice for the possibility of victory, even if this stupid woman was willing.

"Are there any side effects of stripping the Apocalypse Soul Seal, and how much will it affect you?"

Gosling asked first, although he was the leader of the alliance, he really felt sorry for Xi Yunyun, a junior. Although this method is easy for her, it sounds difficult.

"There shouldn't be, this soul mark is just temporarily placed in the Soul Star Sea, and when the battle is over and the soul crystal returns to its place, I can still take it. However, I think even without the Apocalypse Soul Seal, I'll be fine. I also have my own soul crystal, and in addition to my spiritual power, I can also use the magic force. ”

Xi Yunyun didn't think about this problem, she felt that she could achieve this level of sacrifice without a way. Although she also knew that if she only relied on the magic force, her strength would be weakened by at least half.

"Let me think about it again, your Infinite Space-Time Array is also very important. Gosling hesitated.

"The Infinite Time and Space Array has been collected in the Feather of Noble Phantasm Commandments, and I think that when the time comes, as long as the conditions are complete, there will be no Apocalypse Soul Seal. She thought about that, too.

"No, I don't agree. The voice of the killing sky sounded coldly, making everyone stunned.
