i found it, but is mtl: https://www.wuxiabox.com/novel/6955375.html

and if you are searching for a good doulu fanfic then i recommend this https://www.wuxiabox.com/novel/the-peerless-tang-sects-jingtian-douluo.html, it's in the same mtl site, but the traduction is very good and the story is excellent

this is the link: https://www.wuxiabox.com/novel/6938393.html

the story is very bad, after the tournament they nerf mc and make tang san more powerful, every time tang hao is trying to kill mc and the final is very abrupt, is literally him being hitted by tang hao and is transported again to the normal world (before transmigration)
