What Randy felt was hot when he sank down into the boiling lava, but there was only hot, his skin until his hair was fine under the high temperature of lava.
Even though he was fine, but the heat of lava was unbearable for him at first. As time went by, he felt his body was adjusting with the high temperature and the heat which at first unbearable became warm.
Randy let out a sigh of relief at this before letting his right hand appeared to the surface of lava, making a sign for his wife he was fine here.
He knew that his wife didn't immediately leave after telling her his purpose for bathing in lava was because she worried of him. Randy made a sign he was fine for his wife, then he began absorbing the Fire Energy in lava.
Shana told him he only needed to circulate his Fire Elemental Energy inside his body, then his body automatically would absorb the Fire Energy to increase his level of Fire Elemental Power.
