Five-Elemental Sword Array Formations.

Hao Ren switched his focus back to the ancient book in front of him.

Without any Nature Essence, it didn't even differ from any other old books from the used bookstores.

Hao Ren picked up the book and opened to the first page.

The fundamental sword array formations: fire-elemental array formation, earth-elemental array formation, water-elemental array formation, metal-elemental array formation, and wood-elemental array formation.
