682 Refining Group Strength Gu

Fang Yuan could faintly sense Hei Lou Lan's tribulation would result in a huge battle.

Hei Cheng was an experienced rank seven Gu Immortal, his battle strength surpassing Fang Yuan's. Xue Song Zi was the owner of the seventh peak of Snowy Mountain blessed land and was also not an easy opponent.

Even if Hei Cheng and Xue Song Zi did not create trouble, a tribulation of the Great Strength True Martial Physique would far surpass the severity of those of normal people.

Fang Yuan immediately started making preparations after he returned to Hu Immortal blessed land.

He needed to raise his battle strength in a short period of time. Battle strength usually depended on four aspects: immortal essence, killer moves, Immortal Gu and battle attainments.

Fang Yuan was already very strong in his individual fighting attainment and it would be difficult to raise in a short period of time.
