But there are two problems.
One is that it's only ten meters long, a bit too short.
The second is that it currently has only ten thousand HP, and its defense isn't too high... Overall, it's still too fragile.
The HP needs to be increased.
With more HP, it should grow longer. After all, the Iron Tree Vines I've seen before were very long.
Wang Tao thought it was like the Entangling Roots; to increase the HP, either feed it his HP or feed it Crystal Cores.
Turns out Wang Tao tried it, and that didn't work. A prompt also appeared, suggesting that the Iron Tree Vines need to split before they can be cultivated. For example, if it splits into two vines, then Wang Tao could increase its HP to twenty thousand, three vines to thirty thousand HP, and so on.
This is a bit of a headache, but there's a silver lining. That's two vines each with twenty thousand HP!
