"Now you know, why I never use Thunder Scrolls for all the important messages,"
"Ancestor Li, I understand," Lei Yu replied in a deep voice, "because Thunder Scrolls are not safe, merely convenient and cheap. In the past, they weren't intercepted simply because the Lei Clan's prestige was at play. When that prestige doesn't work, naturally one can intercept them whenever they wish."
"Good that you understand," said Lei Li as he took out a new Thunder Scroll and handed it to Lei Yu, "Now, write a letter to Qing Ziyu, and tell him that I am very interested in meeting him."
Lei Yu was puzzled but still did as instructed.
Following that, he saw the Thunder Light flicker in Lei Li's palm, completely absorbed into the Thunder Scroll in an instant, and then everything returned to normal.
"Go, send it out after you get back," Lei Li said.
Lei Yu nodded and left Thunder Collection Mountain.
He did not hurry and waited a day before finally sending out the Thunder Scroll.
