Ever since the Order of Michael was formed, the Church realized that they needed weapons to supplement the power of their men against witches and demons when it came to a real battle. This led to the rapid development of the saint tech which was basically wielding the light to emulate weapons.
The low and medium qualities of the saint tech were mainly made up of weapons blessed and infused with the power of the divine. They were crafted no differently than witch tech weapons. However, as for the high-quality ones, these were basically handing humans a portion of angel power.
So even when a very unstable witch came to kill them, there would be a chance for them to survive.
Just like that, Kace had this advanced saint tech gun in his hand. When Noah activated the space transference, he actually felt the shake in the environment. However, he wasn't ready to suddenly see Noah right in front of him, eyes glowing red from purely dark magic resonating from his soul.
