Transform the World in Douluo

(Douluo Dalu fanfic) Zhang Yilian was sent to a place called Douluo Continent by a certain powerful man due to an accident. When he woke up he found: I have a grandfather who very much doubts whether he is his biological father. There is also a person who is gentle to himself but wants to take revenge on the mother of the world. There is also a sickly sister whose childhood was incomplete and suddenly lost her love. The scariest thing is: He actually has an uncle who wants to make money and kill himself. This... He looked at the old, young, women and children behind him, what a hellish start. Fortunately, he had a plug-in provided by Almighty. (Any deviation from the original work is entirely a second guess.)
