Creating 100 backlinks in a day is not possible. If you do so you will get a penalty.
Now, what I do is whenever i publish new posts. I start searching Quora and look for people who needs help. I try to help them and after I put a link of my relevant article. That they can read more about that topic from my blog.
I always love to help peoples and I do so with the help of forums. You can also ask for guest posts. Backlinks are not too much important factor. On-page SEO matters a lot and you should take care of on-page seo too if you want to rank high.
