It's possible to practice magic this way, right?

"Egg? It's about to be born. Your metaphor is very vivid, but can you change it to something better?"

"It's just an analogy, don't mind it." said Sambrilla.

"Our souls are only in infant form, while you ghosts are in adult form. You are much more powerful than us. What's the big deal?"

"On the contrary, you are different from other ghosts. Your intelligence seems to be quite sound and your thinking is also clear. It seems that you are not affected by the negative emotions of the dead."

"Um... can you put down your sword first? How about we talk about it?"

Seeing that the other party had no ill intentions, Lin Li put away his sword. Then he asked, "What do you want to talk about?"

"First of all, I am indeed like you said, not affected by the negative emotions of the undead."

"Then there is the question of your soul. Although your soul is in the form of an infant, it is much stronger than mine. This is because my soul is illusory, while your soul is between illusory and solid. The quality is completely different."

"Then what? What do you want to say? Or what do you want to do?" Lin Li asked.

Sambrilla did not answer Lin Li's question, but continued: "I watched your previous battle in its entirety. To be honest, you have a mountain of treasure but you don't even know it."

Lin Li frowned and asked, "What do you mean?"

At this time, Dongfang Jing stepped forward and asked, "Are you talking about the power of the soul?"

"Yes, it is the power of the soul. You have such a powerful soul but you don't know how to use it at all?"

"I just said that your souls are much stronger than mine, but I have already reached what you call the legendary level in my current state."

"And you are only slightly stronger than I am now. The only threat to me is the sword of this girl."

Lin Li was stunned for a moment, then asked in surprise: "You mean, we didn't use our soul power at all?"

"You haven't really used soul power. I've been observing you humans for a long time. Your so-called fighting spirit and domain are not the real uses of soul power. Not even the surface."

Lin Li stared at Sambrilla, wondering if what she said was true. And why she told them all this. After thinking for a while, he couldn't help but ask, "What do you want?"

This ghost would not tell them this for no reason. He must have something to ask of them.

"Since you asked directly, I will tell you clearly."

"I can teach you how to truly use the power of the soul, but you have to tell me how to solidify the soul into your form."

To be honest, Lin Li was really tempted. Although he had broken through to the so-called Nascent Soul stage, his combat capability was basically the same as when he was in the Golden Core stage.

Xiao Wu was the same. She had learned the space sword technique when she was a Jindan, and she still used it now. There was no change in power. It was as if they had survived a fake thunder tribulation. Except for the Jindan turning into a Yuanying, there was no difference at all.

After hearing the ghost's words today, Lin Li finally realized that the biggest difference between the Golden Core and the Nascent Soul is the difference in the soul, so improving combat power should also start from the soul.

But in this world, the only ways to use soul power are fighting will and domain, and they cannot use the domain yet.

Now that I have encountered a ghost who claims that he can use the power of the soul, I naturally cannot give up this opportunity.

Lin Li turned around and saw Dongfang Jing nodding at him, obviously having the same idea as him.

"Okay, I'll exchange methods with you. Let's write down the detailed methods and then exchange them at the same time."

After Lin Li finished speaking, he added: "However, both of us must sign a soul contract in advance to ensure that our method of exchange must be real and effective."

"You can sign a soul contract, but I need to make sure your method is effective for me first. Once I am sure, I will teach you how to use soul power."

"Haha, do you think we are stupid? Do you want to get something for nothing?"

"Humph, I am a soul body. The soul contract is fatal to me. If I violate it, I will die."

"But you have a physical body, and your soul is so solid. Even if you are attacked by the backlash of the soul contract, you will not die. If you have something to restore the soul, you can even recover completely very quickly."

"I can sign a soul contract with you. As long as I confirm that your method can make my soul condense into yours, I will tell you how to use the soul."

"And I promise that after you learn it, your combat ability will be greatly improved."

Lin Li shook his head and said, "I have already signed a soul contract with you, why would I lie to you? You should know how rare things that can restore souls are."

"No, you have to let me confirm it first. I am not afraid to tell you that in this world of yours and the undead world below, there is absolutely no one else who knows how to use soul power."

"Haha, then I'll tell you, the three of us in front of you are the only ones who know how to solidify the soul? Not to mention two worlds, you can't find a fourth one even if you search through the entire world group around you."

"Haha, do you believe what you said?"

"You said you were the only three who could do it? And yet I encountered them all at once. This girl isn't even human, and you three aren't even of the same race. You have the nerve to say you're the only three who can do something that people from different races can do."

Lin Li was dumbfounded. To be honest, she didn't believe it. But her analysis seemed to be correct. If they were in the same position, Lin Li himself wouldn't believe it.

"If you don't want to switch, I'll go to your world and find someone else to switch with. Anyway, I can easily tell the difference in souls."

Lin Li sighed helplessly, and then said: "I didn't lie to you, I told you the truth. There are only three of us in the world who can do it. The other two can't tell you because of the restrictions of the contract. Because this method was invented by me. I also taught them personally."

"If you don't trust me, you can look for it in our world."

Sambrilla pondered for a while. She was actually not willing to come to this world because her abilities were greatly weakened in this world and she could be easily discovered by others.

Although she can easily detect people with different souls, these people can also detect her, which means that she is not safe at all.

But she still didn't give up her plan: "No, if you are the only one in the world who can trade with me, then I have to make sure that the method you have mastered is effective for me."

"So you have to confirm it with me first. Then I will teach you the method. If you feel that the soul contract is not safe, we can sign other contracts."
