We describe an efficient algorithm to compute a large number of baryon-baryon interactions from $N N$ to $ΞΞ$ by means of HAL QCD method, which lays the groundwork for the nearly physical point lattice QCD calculation with volume $(96 a)^{4} \approx$ ( $8.2$ fm) $^{4}$ . Preliminary results of $Λ N$ potential calculated with quark masses corresponding to ( $m_{π}$ , $m_{K}$ ) $\approx$ (146,525)MeV are presented.
