"Fire Wall Technique, summons a flame barrier to prevent enemies from approaching, inflicting 100 points of damage per second to those who touch it. It lasts for five minutes and has a cooldown time of one minute."
Perhaps it was because Zhou Tian's level had increased, but while his talent continued to become harder and harder to level up, most of the skills he gained from each level-up had increasingly practical uses. Compared to his previous skills, this Fire Wall Technique was not only powerful, but it could also serve a significant role in most battles. A particularly important aspect was that this skill's cool-down time and duration differed to the point that it allowed Zhou Tian to use it regularly.
And it was due to the conditions of the Fire Wall Technique that Zhou Tian naturally employed it when faced with a swarm of monsters attacking him.
