Ten new targets were selected from the quasar sample of the Sloan Digital Sky Survey (SDSS), which have generally been more luminous than the SEAMBH candidates in the last two years. Hβ lags (τ) in five of the 10 quasars have been successfully measured in this monitoring season. We find that the lags are generally shorter, by large factors, than those of objects with same optical luminosity, in light of the well-known R-L5100 relation. The five quasars have dimensionless accretion rates of dM/dt=10-103. Combining these with measurements of the previous SEAMBHs, we find that the reduction of Hβ lags depends tightly on accretion rates, τR-L∝(dM/dt)-0.42, where τR-L is the Hβ lag from the normal R-L5100 relation. Fitting 63 mapped AGNs, we present a new scaling relation for the broad-line region: R1l44β1min [1,(dM/dt)/(dM/dt)c)-γ1], where l44=L5100/1044erg/s is the 5100Å continuum luminosity, and the coefficients are α1=29.6-2.8+2.7 lt-day, β1=0.56-0.03+0.03, γ1=0.52-0.16+0.33, and (dM/dt)c=11.19-6.22+2.29. This relation is applicable to AGNs over a wide range of accretion rates, from 10-3 to 103. Implications of this new relation are briefly discussed. Description: The super-Eddington accreting massive black hole (SEAMBH) project uses the Lijiang 2.4m telescope, operated by Yunnan Observatories. We adopted the same observational procedures described in detail in PaperI (Du et al. 2014, J/ApJ/782/45). Observational results of the three years spectroscopic monitoring (2012-2014) are listed in table1.
