"Whether or not it was planned, now that he has a new upgrade, using the Heaven-Slaying Weapon has become even more difficult."
The Boundary Breaking Organization doesn't want to use the Heaven-Slaying Weapon, but although the weapon has sufficient power to kill Zheng Yichen, the biggest problem is that it doesn't guarantee a hit!
The Power of Destiny can also be utilized by the Boundary Breaking Organization, but for someone like Zheng Yichen, the power of destiny is hard to completely take effect. Using the Power of Destiny for locking on can indeed achieve a 100% hit rate.
However, that is only a guaranteed hit on Zheng Yichen in normal conditions. If Zheng Yichen uses the Oblivion force, the lock from the Power of Destiny becomes ineffective.
Oblivion, this ultimate destructive force, will also obliterate the fate within its affected range.
