500 Elo in 2 Days

Hey everyone so I do not want to flex or whatsoever, but this used to be my main account during the pandemic. I left it and started playing in alt accounts. After like 2 years I have came back to this account and started playing 30 Sec Bullet for fun. I was 740 Elo at that time. Slowly started getting wins and hit 850 Elo. Then rating started fluctuating with me going to 810 to 845 and staying in the range for a while. Then I started winning a lot, winning against 4 Digit elo players while being 3 Digit elo. Henceforth I hit 1000 Elo, then 1100 and finally 1200. My next aim is 1300. If any people who are above 2000+ in bullet are seeing this forum, kindly advice me.
