It may means "I would go to join the protest against Japan's buying Diaoyu Islands with friends in Wuhan." 热血 may be a noun or adjective to describe someone who fevers to express their emotion to their country.

it‘s an opposite word of 冷血。

well,it should be in a conversation.not just a single sentence.or it's writted wrong. year,it means get wild,get very excited,be very passionate about. "热血澎湃" 比喻献身的热情。

虽然是名词当做动词用，但是这种用法很怪，很少有人这么用。严格来说，这是个病句。这可以算那位网友自己发明的用法。 Apart from meaning warm blood literally, another most common meaning of '热血' is enthusiasm, and often turn up as '满腔(的)热血' 例如: 我们怀着满腔热血投身到共产主义的事业中来。 So you see, it's a rather emotional word, often appears in political propaganda and poems, but rarely used in daily life.

I think it could be you and your friends are doing some crazy thing.
