Sister looked at me and hesitated:

"Sister, you have a strong power within you, but it's being restrained by this shackle."

Upon hearing these words, I immediately felt ecstatic.

Great, does that mean I can protect them?

However, when I saw the expression on my sister's face, I hesitated.

She seemed conflicted for a moment before continuing:

"Sister, if you want to use this power, you need to use a knife to cut the mark on the shackle."

"Then you'll have a chance to use this power, but remember, you can only cut it once."

Upon hearing my sister's words, I nodded.

My sister went back to her room to locate the position of the next spatial rift.

After I returned to my room, I found the notebook.

I spoke to the empty room:

"You are my future self, right?"

A new line appeared in the notebook: 【Yes.】

My fingers trembled slightly, and now many things had answers.

"So, when my sister said to only cut the shackle once, does that mean I won't be able to protect them?"

"No, you can only protect yourself."

"Is there something bad that will happen if I cut the shackle?"

"Yes, by cutting it once, you will gain a small portion of power, but it will be a one-time use."

"If you cut it twice, you will gain all the power, and it will be permanent. However, from then on, you will lose your freedom. To regain your freedom, it will take a very long time, possibly tens of thousands of years."

"If I only cut it once, what about my sister and the others..."

【They will all die.】

When I saw the three words in the notebook, tears uncontrollably streamed down my face.
