章節 532: Chapter 316: Exchange, Divine Skill: Law of Heaven and Earth_2

```

Ye Feng was pondering while swiftly exchanging Spirit Plants. Out of the 35 types of Spirit Plants, 34 could be exchanged freely, as long as they were cheap enough.

But there was one specific kind that was necessary.

Just like when Ye Feng was cultivating the first level of the Divine Wood God Body, he eventually had to refine a stalk of Golden Silk Dragon Grass to truly master the technique and enter the threshold of the Divine Wood God Body.

It was the same for the second level; ultimately, a plant called "Void Python Vine" had to be refined to advance and reach the minor boundary of mastery.

Ye Feng quickly located the "Void Python Vine," but after seeing the exchange price, he couldn't help but twitch at the corner of his mouth—it cost a whopping 500 points.

"Isn't this way too expensive!" Ye Feng couldn't help but feel speechless.

The other 34 types of Spirit Plants he chose were all the cheapest ones, and altogether they only amounted to about 50 points.
