First condition to reach the grade 4 battle-axe dao

'Huh?'

Ajax frowned when he heard the huge battle-axe's hoarse voice in his head.

"What is it?"

Nevertheless, he asked the huge battle-axe what it wanted from him.

For him, he had to reach grade 3 in battle-axe dao in the next 10 hours and his only chance to do that was with the help of the huge battle-axe.

"Master, I need some essence of nature to give you the knowledge of battle-axe's dao which was locked by my previous owner,"

The battle-axe replied to Ajax after a little hesitation.

'So, it is the reason why it wanted some essence of nature from me?'

Ajax understood that the huge battle-axe was in its weakest form and needed some essence of nature to unlock its true potential. However, for him, the essence of nature is not a problem. So, he agreed to its request before asking, "How much essence of nature do you need to transmit all the knowledge about the grade 3 battle-axe dao?"
