I found a very stupid way to save my (Screen) data for each block instead of using (ContainerScreen)

public class Mp3Gui extends Screen {

...

public class BlockMp3 extends BlockBase {
    @Override
    public ActionResultType onBlockActivated(BlockState state, World worldIn, BlockPos pos, PlayerEntity player, Hand handIn, BlockRayTraceResult hit) {
        if (!worldIn.isRemote){
            Mp3TileEntity t = (Mp3TileEntity) worldIn.getTileEntity(pos);
            System.out.println("server send Gui packet");
            MySimpleNetworkHandler.INSTANCE.send(PacketDistributor.PLAYER.with(() -> (ServerPlayerEntity)player), new GuiDataPacket(my gui data);
            return ActionResultType.SUCCESS;
        } else {
            f(worldIn,pos);
        }
        return ActionResultType.SUCCESS;
    }
//Use this to cheat the inspection
    @OnlyIn(Dist.CLIENT)
    private static void f(World worldIn, BlockPos pos){
        System.out.println("client open gui");
        Mp3Gui mp3Gui = new Mp3Gui((Mp3TileEntity) worldIn.getTileEntity(pos));
        Minecraft.getInstance().displayGuiScreen(mp3Gui);
    }

and in dataPacket

public class GuiDataPacket {
public static void handle(GuiDataPacket msg, Supplier<NetworkEvent.Context> ctx) {
        ctx.get().enqueueWork(() -> {
            World world;
            try {
                //clint to server
                ServerPlayerEntity sender = ctx.get().getSender();
  //at client it will produce null pointer exception
                world = sender.world;
            } catch (NullPointerException e){
                //server to client
                world = getClientWorld();
            }
            if (!world.isRemote) {
                System.out.println("server receive gui packet");
                if (world.getTileEntity(msg.blockPos) instanceof Mp3TileEntity) {
                    Mp3TileEntity mp3TileEntity = ((Mp3TileEntity) world.getTileEntity(msg.blockPos));
                    set my tile entity
                }
            }
            if (world.isRemote){
                System.out.println("client receive gui packet");
                if (world.getTileEntity(msg.blockPos) instanceof Mp3TileEntity) {
                    Mp3TileEntity mp3TileEntity = ((Mp3TileEntity) world.getTileEntity(msg.blockPos));
                    set my tile entity
                }
            }

        });
        ctx.get().setPacketHandled(true);
    }
  //Use this to cheat the inspection
  @OnlyIn(Dist.CLIENT)
    private static World getClientWorld(){
        return Minecraft.getInstance().world;
    }

it does work.
