High pressure plays growing importance in discovering new high Tc superconductors (SC) by design. Here we present our research on new SC advancements in combinations to high pressure technique^[1] including cuprates SC of Cu12(n-1)n homologues series^[2] with ambient Tc 118 K, Ba₂CuO_3+y of unique compressed copper oxygen octhedron leading to mixed orbital features of both 3dz² & 3dx²-y² yet with ambient Tc 73K^[3] that is more than 80% enhancement over those for 214 of universal elongated copper oxygen octhedron; the “111” iron based SC^[4] & the pressure induced SC in topological compound of Bi₂Te₃^[5]; the superhydrides SC of calcium with Tc above 210K^[6], the record high Tc SC created in element Titanium(Ti) ^[7] & Sandium(Sc)^[8] consequently. We further discuss briefly the prospect to room temperture SC.
