In this paper, study the module structure of Ext_BP*BP⁰(BP_*, BP_*/(p , v₁^∞ , v₂^∞ )), which is regarded as the chromatic E₁-term converging to the second line of the Adams-Novikov E₂-term for the Moore spectrum. The main difficulty here is to construct elements x(sp^r/j;k) from the Miller-Ravenel-Wilson elements (x_3,r^s/v₂^j)^pk ∈ H⁰M₂¹. We achieve this by developing some inductive methods of constructing x(sp^r/j;k) on k.
