Bab 352: The Base City of Jiangnan

A familiar only needed to be fed huge quantities of elemental stones of the same element in order to return to a certain grade that it had fallen from after reaching a new tier.

The Thunder Shell Lord was Epic-grade when it was still a Commander-tier familiar. When it reached Lord-tier, it had fallen back to Perfect-grade. In the past few months, it had been gobbling up Electric-type elemental stones in order to return to Epic-grade. With the Stone of Thor, it was able to make the leap to Legendary-grade.

"When I used the Stone of Thor on the Thunder Shell Lord, it instantly became Legendary-grade," said Ji Hanwu when he set the dishes on the table.

Then he sighed as he looked at his grandson admiringly. He opened his mouth as if to say something, then closed it.

He patted Gao Peng's shoulder and said, "Walk this path well, Gao Peng. I know you can go far on it."

In truth, his grandson had given him quite a surprise.
