results = {{{V -> 26.5173}, {V -> 340.686}, {V -> 191821.}}, {{V ->
     26.6798}, {V -> 326.358}, {V -> 135843.}}, {{V -> 26.8489}, {V ->

      72039.1}}, {{V -> 27.209}, {V -> 287.932}, {V ->
     53792.5}}, {{V -> 27.4009}, {V -> 276.484}, {V ->
     40774.4}}, {{V -> 27.6013}, {V -> 265.647}, {V ->
     31339.2}}, {{V -> 27.8109}, {V -> 255.384}, {V ->
     24398.6}}, {{V -> 28.0302}, {V -> 245.661}, {V ->
     19221.5}}, {{V -> 28.26}, {V -> 236.446}, {V -> 15312.4}}, {{V ->
      28.501}, {V -> 227.71}, {V -> 12322.2}}, {{V -> 28.754}, {V ->
     219.424}, {V -> 10009.8}}};

then

tmp = V /. results

or

tmp = results[[All, All, 1, 2]]

Flatten[Partition[tmp, {3, 1}], 1]
