I Only Sell Murder Houses

At first, I did not understand what the note meant. I had only understood the first point: Seventh Master would be in danger.

But I had already cast a hexagram for him before we came. It was an ominous one, so trouble had been inevitable.

Then there was the second point.

It told me not to casually use what I knew, but to save it until the very end.

I had not understood it at all back then.

The only art I possessed was the Hexagram Art.

But before we reached Lincheng, I had never truly used the Hexagram Art. Even I did not know I possessed it, yet the person who gave me the note somehow did.

Third: do not kill the great Ghost.
