Sikong Jing is the Master of Ten Thousand Beasts. With his current realm, it is not difficult to simulate a myriad of battle body situations superficially, as long as he tweaks the attributes of the Wolf King's power. After all, many battle bodies are created through the bloodlines of demon beasts.
If it were an ordinary person inspecting, it would be quite difficult to detect any issue.
After all, in this world, besides battle bodies, there are even purer beast battle bodies.
However, if a powerful being like Mieqing Venerable were to investigate, Sikong Jing would have to expose the fact that he's a non-combatant.
As for the blood patterns covering his body now…
There are reasons such as the meridians embedded by the Blood Charm Demon Cat, and of course, the terror of the Absolute Night Wolf King's blood.
With Sikong Jing's current beast body, he couldn't withstand even a trace of the strongest Fierce Beast's blood!
