In the past few years, most of the rune stones Connie had collected for Joelson had been devoured by Lightning, so much so that its strength had even surpassed Du Lu's.
He was the most cunning one. He first devoured a large number of low-level rune stones and, when he was strong enough, he would roam the wilderness to hunt for higher-level rune stones.
It was unknown when it had become the most powerful dragon under Joelson's command.
Lightning's huge head came in front of Joelson. It opened its mouth wide and rune stones of various elements poured down like rain.
Most of them were stone runes. There were also quite a number of gold-level runes. The number was more than what Connie had collected. This was what it had left for Joelson.
"At least you still have some conscience."
Joelson smiled as he stroked Lightning's head. The latter narrowed his eyes and acted coquettishly like a big dog.
