After obsessively reading the contents of the Sword Essence chapter, word for word, from beginning to end, Jian Wushuang finally raised his head and breathed deeply, with a hint of shock in his eyes.
"How is it going?" Sima bu asked.
"Very good, especially the chapter on Sword Essence." Jian Wushuang nodded his head and said seriously," when my father was teaching me swordsmanship, he mentioned Sword Essence. But I didn't understand what Sword Essence really indicated until now. I finally know that Sword Essence is formed by comprehending the Essence of Heaven and Earth.
"Yes, in fact, it is a matter of understanding and using the natural power of Heaven and Earth. Watch this."Sima bu said, then smiled and abruptly pulled out the sabre at his waist, immediately attacking a rock that was several meters away.
A sharp crack appeared on the rock and a large amount of rubble fell.
