I would appreciate if someone could help me identify this bike? I can't seem to find the serial number I'm the usual spots!

Detailed pictures of the right/drivetrain side would definitely help but from what we can see and read on the picture, it is a Norco Fluid FS 3 of an unknown year, but definitely earlier than the 21-23 models still visible on their product page.
I was using this site to compare it against previous generations of the Fluid. Looks like it is older than the oldest model shown there (2018). The sloped top tube only occurs on older models.
Some other observations
So my guess is that you have a Fluid FS 3 from the early 2010s and some modifications were made to ride it on a daily basis or on easier terrain.
