"Because I have the proof." Lin Tian spoke. "Let me show you guys too."
Then he took out a projection artifact from his storage pouch. Then he activated the artifact.
With a dazzling light, a huge visual image appeared above the arena.
"W-what is this? A letter?"
"Seems like it."
"Yeah..."
"Woah! H-he will become Elder Yuan's disciple?"
"I'm so jealous! I want to fight and be a disciple of Elder Yuan too."
Lin Tian was pleased as his plan worked. He wanted to use this chance to make it bigger. {And now, Elder Yuan will have no way of fighting back!}
"Yes, as you guys can see this is the letter Elder Yuan personally gave me." Lin Tian shouted at the crowd pointing at the paper in his hands. (Note: In chapter 68, Yuan left a letter to Lin Tian.)
"He even gave his signature which proves this is real." He showed the other side of the paper.
