Yes! Lin Yi suddenly thought of something-the earth-opening claw was a fire element martial skill, and the wild fire Fist was also a fire element martial skill. So these two skills could be combined, using the wild fire Fist's chant and the earth-opening claw's activation method, the two combined to form a new martial skill.
However, the wood forest thousand transformation was different. This was a wood attribute mental cultivation method, and it was not of the same attribute as the fire attribute's heaven and earth splitting claw. This should be the reason why the two combined but did not succeed in activating it!
