We present high-resolution optical emission spectroscopy observations of the ultra hot Jupiters (UHJs) TOI-1431 b and TOI-1518 b using the PEPSI spectrograph on the LBT. We detect emission lines from Fe I with a significance of 5.40$\sigma$ and 7.85$\sigma$ for TOI 1431 b and TOI-1518 b, respectivel...
