Chapter 74: Item Fusion part 2
Just like what Kayn had done when he directed the mana from his hand to the Ice Sword, this time he directed the mana from the Ice Sword to the Molten Sword.
However, unlike before, he also has to simultaneously direct the mana of the Molten Sword to the Ice Sword as he has to connect the two mana in the center. Otherwise, he won't be able to achieve what Natas wanted him to perform.
In just a short moment, Kayn starts sweating on his forehead as he experiences trouble with directing the mana of the Molten Sword.
Controlling mana is honestly not something that a Superhuman is proficient at doing. They can indeed control mana, but because of the fact that they aren't Heroes yet and haven't chosen what main class they want to pursue, thus their level of control is subpar because their mana capacity can't handle the requirements to perform the task.
