Most potent poison in all of wuxia?

[Ken Cheng]

The use of poisons is a staple of wuxia stories, but of all the poisons featured in wuxia, which one do you believe is the most potent? Is it Teen San Tung Lo's Life/Death Talisman? The assorted poisons of Ding Chun Chou? West Poison Au Yeung Fung's poison? Something from the Gu Long universe?

How do you measure potency, though? The speed with which it kills, or the difficulty in curing, or the various cute and unique features of each poison?

Lol, this one is easy. In the 2006 movie, The Banquet (https://en.wikipedia.org/wiki/The_Banquet_(2006_film)), the Crown Prince visits a herbalist and asks for a strong poison potion. After being given one bottle of it, The Crown Prince asks if there is any poison stronger than it, to which the herbalist replied, "a person's heart".

If we are talking about viciousness I would say Western Venom has the edge, as his poison has an almost infinite capacity to kill, as seen in the shark incident.

Tianshan Tonglao's and Ding Chunqiu's poisons are quite powerful, but seems more focused on inflicting suffering than outright killing people.

As a special mention I think Eastern Heretic's poison should not be underestimated. His concoctions are incredibly versatile.

How about that mixture of poisons that Cheng Lingsu had to sacrifice herself for to save Hu Fei?

And in Gu Long universe, you can't go without the Tang family in you want to poison someone.

Was the Life/Death Talisman a poison? I thought it was an internal energy technique.

Anyways, most painful poison might have been 鲜于通's 金蚕蛊毒 from HSDS (天下毒物之最。无形无色，中毒者有如千万条虫在周身咬啮，痛楚难当，求生不能，求死不得)。

三尸脑神丹 from SPW also seemed quite scary- makes bugs eat your brains and makes you eat your own family..... eh.

The most powerful one might have been 金波旬花 (India's Devil Flower) in A Deadly Secret, which even restricted Ding Dian's Shen Zhao Jing Powers. (丁典道：“当时我怎么猜想得到？更哪知道这金色的花朵，便是奇毒无比的金波旬花？‘波旬’两字是梵语，是 ‘恶魔’的意思。这毒花是从天竺传来的，原来天竺人叫它为‘恶魔花’) (不料那毒药当真厉害，刹时间消功蚀骨，神照功竟已使不出来。)

Of course the worst in my opinion would be Passion Valley Flowers since it essentially stops you from being able to Love.
