I never really like these types of arcs... they make it seem like its super easy to tame something. Like even some random was able to tame a marten or whatever an Banana wombat is (like wombat sure but banana?). Anyway if it was so easy to just tame some giant snake, why doesn't one create an army of them and then rules the world? Like every noble brat should run around with like 3 giant fire lions at this point if it was so easy to tame a beast and then just hand it of to someone else.
Usually it should take weeks and months to even tame a little beast and years to tame a strong one. Since one can quite literally double or more their own combat power just cause they tamed something.
