A method for construction of rational points over elliptic curves

I provide a systematic construction of points (defined over number fields) on Legendre elliptic curves over $\mathbb{Q}$: for any odd integer $n\ge 3$ my method constructs $n$ points on the Legendre curve and I show that rank of the subgroup of the Mordell-Weil group they generate is $n$ if $n\ge 7$. I also show that every elliptic curve over any number field admits similar type of points after a finite base extension.
