Hun!
'These bastards looked really do want to kill me and painfully at that,' The Scarlet Vein Snakeman had used its special poison, the most powerful poison its bloodline have provided it, the vein shrieker.
I have heard about the vein shrieker; it is an absolute nightmare as it makes them powerless, stopping all the passage of energy in their veins; not only that, one also feels a horrifying amount of pain in their veins as it poisoned them to their core.
Many people have turned permanently crippled by this poison; it is a good thing, there are some side effects of using it, that even scarlet vein snakemen think carefully before using it.
They could only use this poison once a month, and every time they use it, they will be weakened for a week time. It is a very serious disadvantage in the fight, you may be able to kill one Master, but others might kill you, not to mention, you will be nearly powerless for a week.
