We present the first results from JWST ASPIRE program (A SPectroscopic survey of biased halos In Reionization Era). This represents an imaging and spectroscopic 25 reionization-era quasars their environments by utilizing unprecedented capabilities NIRCam Wide Field Slitless Spectroscopy (WFSS) mode. will deliver largest ($\sim280~{\rm arcmin}^2$) galaxy redshift at 3-4 $μ$m among Cycle-1 programs provide extensive legacy values for studying formation earliest supermassive black holes (SMBHs), assembly galaxies, early metal enrichment, cosmic reionization. this paper, we report discovery a filamentary structure traced luminous quasar J0305-3150 ten [OIII] emitters $z=6.6$. has 3D overdensity $δ_{\rm gal}=12.6$ over 637 cMpc$^3$, one most overdense structures known in universe, could eventually evolve into massive cluster. Together with existing VLT/MUSE ALMA observations field, our reveal that traces complex environment where both UV-bright dusty galaxies are present, indicate evolution around is not simultaneous. addition, discovered 31 field other redshifts, $5.3
