Right now, what Uchiha Brahman was using was the Divine Blessing Potion laced with a powerful anesthetic. A single dose was enough to instantly knock out a whale. What did that mean? It meant that if this stuff hadn't been mixed into the Divine Blessing Potion, and had been injected straight by itself, it would have been absolute death.
Even with this grade of Divine Blessing Potion, if Uchiha Brahman hadn't casually added some protective agents while brewing it, this injection would have undoubtedly caused over-suppression of the central nervous system, leading to severe consequences such as respiratory failure and cardiac arrest. If the person died before the effects of the Divine Blessing Potion could even manifest, that wouldn't have been the outcome Lord Brahman wanted.
"All praise to Lord Brahman! The great Loving Father! Ahead is Kumogakure!"
