Is a Sudden Increase in Backlinks Risky for Google Rankings?

Hello everyone, I’ve been running my website for about 4-6 months now and recently found around 30 high-quality niche-specific backlink opportunities. I've written unique, varied articles and I'm ready to reach out to the site owners to have them published. These blogs and websites are highly rated on Ahrefs, and about 90% are directly relevant to my business niche. My question is: if I go from having 5-10 backlinks to around 35-45 within a few weeks, could this raise a red flag with Google? Is there a risk of being penalized or shadow-banned for this sudden spike in backlinks, even if they are legitimate, high-quality links? I’d love to hear your thoughts or any experiences with similar situations. Thanks! (i have make chatgpt this post because my english is not that good )
