Ren's mind was full of wonderful messages.
[You have leveled up!]
[You have reached Level 2!]
...
[You have reached Level 5!]
[You have gained 20 Stat Points.]
From one quest, he had jumped four levels. This was amazing. A normal adventurer would need weeks to do this.
"Are you... okay?" Lyra's voice asked. "You were standing there with a creepy smile on your face."
"Was I?" Ren asked, his smile becoming very charming. "Sorry. I was just thinking about my reward." He started to collect proof from the dead goblins.
"You can't be an F-Rank," Lyra said. She was very confused. "I am a C-Rank Knight, and I had trouble. You beat them in ten seconds."
"I told you," Ren said. "System Glitch. Very buggy."
They began to walk back to the city of Eridon. On the way, three other adventurers blocked their path. Their leader was a big man with a mean face. He looked at Ren's simple clothes.
"Well, well, Lyra," the man sneered. "Why are you with an F-Rank charity case?" His friends laughed.
Lyra got angry. "Back off, Borin."
Ren put a calm hand on her arm. He smiled his sweet, angelic smile at Borin. "No need to be rude," he said.
"An F-Rank like you will end up as goblin food," Borin said with a laugh.
The smile on Ren's face did not change, but his eyes became very cold. The playful feeling was gone. Now, he felt dangerous.
"You are probably right," Ren said, his voice a soft whisper. "It's a dangerous world. Full of glitches." He took a small step closer to Borin. "And some glitches... you don't recover from. You should be careful."
Borin and his friends felt a sudden chill. The boy looked like an angel, but he felt like a reaper. They were scared.
"Whatever, freak," Borin said, and he and his friends quickly walked away.
Lyra stared at Ren. She had seen a scary side of him. "What was that?" she whispered.
"Just friendly advice," Ren said cheerfully. The warm, playful feeling was back.
They arrived at the Adventurer's Guild. Ren knew the easy part was over. Now, he had to explain how an F-Rank adventurer killed a whole nest of goblins. This was going to be fun.
