Absorbing Spirit Veins for cultivation, Yan Rufeng indeed gained immense benefits. After absorbing one Spirit Vein, he immediately used sword flight to search for the next Spirit Vein.
When Yan Rufeng had absorbed ten Spirit Veins, the Golden Core within his Dantian finally formed the Seven Stars Gathering configuration. The more Golden Cores there are, the more Spiritual Energy is required.
After Yan Rufeng absorbed another Spirit Vein, he exhaled a long breath, "Seven Golden Cores require a whole Spirit Vein to be filled. It seems that even if I absorb all the Spirit Veins in Japan, I can't reach twelve."
Yan Rufeng continued flying on his sword in the sky above Japan, searching for Spirit Veins. As he approached the sky above Dafu Mountain, he suddenly became excited.
"I didn't expect there to be a small Spirit Vein that's been forming for a long time here. This trip to Japan is destined to be fruitful."
