Every demon will come to be aware of its weakness in the demon hierarchy. How they're dominating the human race and other creatures was just child's play compared to what the true demons at the top had.
This came around the age of 1 year old when usually a demon has enough spiritual energy to further their spiritual body cultivation and take control of their path. That was what happened to the Leopard demon after it had consumed the spiritual energy of ten thousand humans from a town.
Typically demons are not able to grow their spiritual energy after they are born because spiritual energy doesn't grow after a creature is born much less when it's not exposed to the harsh environment and isn't stimulated. This protection from the outside elements allows demon spiritual energy to never decay or have to face the terrifying death spiritual energy that occurs when a creature is close to the end of its lifespan, allowing them to live forever.

Simply having more spiritual energy wasn't enough for a demon to survive in this world unless they planned to bury themselves deep into the earth and never come out. They needed to use their spiritual energy in more effective manners. They needed to make use of their talents in spiritual body cultivation and push their existence to new levels.
When the Leopard demon understood this demon law of survival it stopped its reckless destruction of human settlements as it was making it an easy target for stronger demons. It then focused on making use of its talents to create techniques and methods of combat that could kill demons.
After a few years, it had done it and managed to be able to manipulate its spiritual energy to create spikes and use it to suppress other creatures. However, what the Leopard demon was most proud of was it managed to integrate its spiritual energy further into its flesh, blood, and bones.
It could control its body in ways that only creatures like slugs and boneless creatures could. It could seal wounds and even survive wounds that went straight through its body.
The Leopard demon even could send a majority of its spiritual energy into the body of other creatures by pumping spiritual energy into a glob of its blood before sending it to the target. This way the Leopard demon could actively attack other creatures from inside their bodies and even engage in spiritual battles with added protection from its physical blood.
The Leopard demon felt proud of this method of attack but knew better than to feel like it was unstoppable. While it knew better than to be arrogant since there were many demons and monsters much stronger than it at heart, following its own advice in practice was difficult.
With a method to fight against demons, the Leopard demon went out to hunt demons before quickly running into a brick wall. A demon that was covered in metallic black spikes, had no limbs, no eyes, or even other sensory organs other than a mouth filled to the brim with razor-sharp teeth.
"A young demon with such a powerful ego, I'm going to enjoy eating you." The black spiked demon licked its teeth in a high-pitched voice.
The Leopard demon at the time felt the powerful aura that the black-spiked demon had and knew that to survive it needed to use its trump card. Without responding to the black spike demon, the Leopard demon buried itself into the ground and shot an arrow of its blood filled with a majority of its spiritual energy at the black spiked demon.

In the illusion of being in a superior position, the Leopard demon at the time didn't realize it was trapped inside the black spike demon's body without a way to escape.
Once its escape was sealed the black spiked demon went on the offensive and beat the Leopard demon into submission simply due to how much stronger it was. Just as the Leopard demon was on the verge of being devoured it heard the black-spiked demon chuckle before spitting it out.
"Hehehe, that was a fun game we played but since you lost and don't want to die how about you join the demon union?"
After that day, the Leopard demon swore to never allow itself to be trapped again. It even modified its technique to have some of its blood keep the small hole it made to enter the creature's body open allowing him to have an emergency escape route.
Not even a year after it joined the demon union it found itself trapped once more inside a demon it had invaded. Even the small hole that it kept open as an escape route was forcefully shut.
With the Leopard demon trapped inside Yoze's body, it was both frustrated and terrified as it was now in a life-or-death scenario. The Leopard demon either won and killed Yoze or Yoze would devour the Leopard demon.
In such a life-and-death situation the Leopard demon couldn't risk wasting its time trying to chew through Yoze's tough nerves and focused on dealing with the much bigger threat to its life, Yoze's spiritual energy.
The Leopard demon rushed directly toward Yoze's spiritual energy paths, eating his flesh along the way to create a path. However, it didn't take long for the Leopard demon to feel heavier and begin to slow down.
Due to the Leopard demon's lack of ability to sense inner vigor, it wasn't aware that it was consuming Yoze's Big Golem inner vigor along with the flesh. The weight of the Yoze every strand of inner vigor that the Leopard demon ate was many times the weight of the Leopard demon's blood causing it to slow down from the sheer weight inside its blood.
