Well as we all know that whenever we transact it always go through blockchain first. So is it possible that blockchain can detect illegal trasanction such as buying drugs, guns, hitman etc., especially on deepweb. And where does bitcoin go when blockchain detects a illegal transaction?

There are companies that do aim at detecting and monitoring illicit transactions in bitcoin for use by law enforcement, governments and merchants. For examples

https://www.elliptic.co/
http://www.coinalytics.co/
http://sabr.io/

An they can do this because bitcoin is not anonymous, but only pseduo-anonymous.

Wow I didn't even know that Bitcoin reconnaissance is even a thing until now. Elliptic are saying on their website that they can trace Bitcoin addresses of dark web entities wow can they really do that? I thought deals on the dark web are very hard to track down if not impossible. Maybe they have developed an algorithm to datamine suspicious transactions or something because if they are doing this manually it sounds crazy.

Thats exactly what they do, datamine blockchain + publicly available information + information from exchanges, law enforecements etc. Once they connect a single address of a user with his/her real identity, they just follow the blockchain trial. Everything is in blokchain, as its public ledger.
