Articuno had noticed it, and as the healer, Su Hao naturally noticed the culprit hindering his treatment and preventing Ancient Sword Leopard from healing itself.
"Negative energy..."
Sensing the energy within Ancient Sword Leopard, Su Hao's expression grew more solemn.
Ancient Sword Leopard's current condition somewhat resembled a rejection response.
On one side was the foreign negative energy.
On the other was the Calamity Power within it: a purer aggregation of malice, negative emotions, curses, and other things that existed as a justified part of the world itself.
These things had transformed Ancient Sword Leopard, once an auspicious artifact, into one of the Calamity Treasures, binding themselves deeply to it.
Compared to something from another world, the equally exclusionary Calamity Power naturally had no intention of letting negative energy invade and merge with it.
The two sides were locked in a fierce struggle inside Ancient Sword Leopard's body, preventing it from relying on a Legendary Pokémon's physique to heal itself.
Ancient Sword Leopard had never been affected by negative energy to this extent before.

He just did not know what specific directions their research had taken.
No one knew how many years their arrangements on Blue Star had been in place. Everything remained unknown.

Without affecting Ancient Sword Leopard's essence, they needed to purify and eliminate the negative energy within its body.
Fortunately, Ancient Sword Leopard was relaxed now, so its instinctive resistance would not be too fierce. Diancie and Milotic were veterans
