So, when those elemental spirits launched an attack on Zhou Tian, their goal was not to inflict real harm or even to kill Zhou Tian. Their only purpose was to hinder Zhou Tian's advancement.
Indeed, the actions of those elemental spirits did have some effect.
However, no matter how skilled Zhou Tian was, he could not guarantee that the attacks of those elemental spirits would not cause any destruction. Despite the attacks, they did not cause any significant damage to Zhou Tian. Yet, their tactics obliterated the path Zhou Tian trod on. Since Zhou Tian cannot fly, the destruction of the path adds a handicap to his escape speed. As a result, it is not impossible for him to get hurt by the volcanic magma.
"Damn it!" Zhou Tian gritted his teeth in resentment towards those elemental spirits that obliterated his path. But he knew that now is not the time to deal with them. His main concern was how to save his own life before magma came rushing in.
