The Cage of Evil's iron bars triggered the Charging Bullets, which boast high movement speed and auto-tracking features. However, during the tracking process, these bullets could be attracted by other creatures, bringing trouble to those creatures that come too close.
If Song Jian had not heeded Situ Kaiss's advice and used the Thousand Swords Art to attack and destroy the Cage of Evil, he could have been easily killed on the spot by the triggered Charging Bullets if he was too close.
Although Song Jian possessed "Death's Bane," a passive skill that could resurrect him automatically, he had no desire to experience what it felt like after death.
When the Death Lord saw Song Jian get blown away, the distance between him and the Soul Crystal in his hands grew even further, which infuriated him even more.
Hit by dozens of Charging Bullets and sent flying like an empty sack, the Death Lord relentlessly got up from the ground once more and continued to charge towards the iron bars.
