The white haze started to gather around both of Matthew's hands and it didn't take longer than 5 seconds for the aura gauntlet to form on Matthew's hands.
Matthew wanted to create an aura blade right away, but when he poured out more aura towards his hands, the aura gauntlet just formed more naturally. So he lets his aura form the gauntlet first before taking his time slowly to create the aura hand-blade.
With his hands covered in a solid aura gauntlet that had its fingers in a fist position, Matthew was forced to rely on his tongue and his legs to stay glued to the tree trunk as he still couldn't make fully functioning fingers on the aura gauntlet due to the complexities of the shape.
But it wasn't a hard task for Matthew since his tongue has plenty of strength and half of Matthew's weight was actually supported by his legs. So he was able to pour his focus on shaping the aura on his hands instead.
