The first skill, No Damage was not an invincible skill. It also had a flaw, or rather, it still had a flaw, which was its stamina. When he activated the skill, in that instant, it could defend against heaven-tier attacks. However, it also consumed the stamina of the user of the skill. The stronger the attack, the more stamina it consumed!
Lin Xuan had leaped into the group of wild monsters outside the city wall previously. After activating the No Damage skill, he only lasted for two seconds. That was because his stamina was exhausted, and the skill had automatically shut down.
At that time, in the group of wild monsters, not only were there yellow-ranked wild monsters but there were also some hidden mystic-ranked wild monsters that had attacked Lin Xuan at the same time. If it was not for the existence of a second skill, which saved Lin Xuan's life… his life story would have ended right there and then.
