In summary, the person is seeking recommendations for introductory books on number theory before delving into analytic number theory for their research project. They mention that their advisers are not familiar with general introductions to number theory. One recommendation given is "A Classical Introduction to Modern Number Theory" by K.Ireland and M.Rosen, but the person mentions it does not fit their needs. Another suggestion is "Elementary Number Theory and Its Applications" by Kenneth Rosen, which is a concise and simple treatment of the basics of number theory and can be found used for a low price.

Could you recommend me some brief, introductory books on the number theory I can read for few weeks before jumping into the analytic number theory? Big part of my near-future research project will involve a lot of the analytic number theory, so it is needed to read books like Iwaniec and Davenport. Unfortunately, I am not quite familiar with the basic number theory, so I thought it would be wise to seek your recommendation. Unfortunately, my advisers learned the NT from algebraic and analytic aspects, so they are not familiar with the general introduction.

"A Classical Introduction to Modern Number Theory (Graduate Texts in Mathematics)", by K.Ireland , M.Rosen.

I just took a brief look at that book, and it does not fit with my need. I just need a concise introduction to the basics of NT before reading the analytic NT>

If you want something really basic, you could try Elementary Number Theory and Its Application by Kenneth Rosen. The 4th edition can be had used for very little.

It's a very simple treatment, but I do still find it useful as a reference for some topics.
