The pressure one faced when triggering the Ultimate Lightning Tribulation was terrifying, especially given its power: it carried the might to destroy heaven and earth. Even an extremely powerful defensive Natal Dan Artifact might not withstand such an attack, let alone a Natal Dan Artifact that wasn't known for its defensive strength.
If even a powerful Natal Dan Artifact could be blasted to dust by the Ultimate Lightning Tribulation, then an energy arrow condensed from energy stood no chance. After all, even an energy arrow condensed by Ling Tian, with his profound mastery of the Arrow Embryo, might not be as sturdy as a powerful Natal Dan Artifact. That remained true even if he infused the arrow with High-level Outer Realm Power and Ultimate Lightning Tribulation Power.
The Ultimate Lightning Tribulation would destroy the energy arrows outright, so breaking through the firmament with them was clearly impossible. It would even be difficult to weaken the Tribulation Cloud. Once Ling Tian realized this, his expression turned grave.
At that moment, Po Qiong bluntly said he had a solution. When the Ultimate Lightning Tribulation came, he intended to use Entity Arrows—in other words, to employ the arrows such as Zhu Xian.
Although the arrows such as Zhu Xian weren't defensive Natal Dan Artifacts, their materials were exceptionally powerful and their grade extremely high. Their defensive strength surpassed that of many powerful defensive Natal Dan Artifacts. More importantly, the arrows such as Zhu Xian had been tempered by the Ultimate Lightning Tribulation for all these years, so they might well withstand its attacks. As long as they weren't destroyed, they would have a chance to threaten the Ultimate Lightning Tribulation and break through the firmament. The attacks of the arrows such as Zhu Xian were undoubtedly the strongest in the entire God Realm,
