'Which letter? Was it the letter that the Cold Hunting King wrote to Lingling, and it took many years before she finally received it?' Moreover, the letter was received in the form of a commission.
Lingling's father, The Cold Hunting King, wrote a commission before he fought the Red Demon to death. He had entrusted the experts from the Hunter Union to kill the Red Demon Kazuaki.
But the Red Demon Kazuaki had tampered with the letter of commission. As a result, it took more than a decade before Mo Fan and Lingling finally received it.
"The Red Demon Kazuaki commissioned us to kill the young Red Demon Lu Kun in order to obtain my father's soul. It fulfilled my father's last wish with the aim of obtaining one of the Eight Souls, which is the Rightful Soul," said Lingling.
Mo Fan nodded.
The young Red Demon Lu Kun was no more than one of the Red Demon Kazuaki's pawns. The Red Demon Kazuaki used it to gain the Cold Hunting King's Rightful Soul.
