The current time period, for the breeding season of the musk oxen, is considered somewhat late, but not too late; a transitional period.
For the herds of musk oxen, this is undoubtedly very challenging because they will form a formation.
Under normal circumstances, musk oxen seem very docile; to conserve energy, they move particularly slowly, always appearing lazy.
But when a herd of musk oxen feels threatened, they will circle up facing the enemy, hiding the calves in the middle.
If the enemy is a wolf pacing around the herd, the herd will rotate with it, positioning the strongest oxen directly in front of it, with others as support.
To the musk oxen, Bi Fang was that wolf.
In such a situation, trying to tackle it alone was almost equivalent to a death wish.
