	abstract = {We report a detailed CO(1-0) survey of a galaxy protocluster field at 
\$z=2.16\$, based on 475 hours of observations with the Australia
Telescope Compact Array. We constructed a large mosaic of 13 individual
pointings, covering an area of 21 arcmin\${\textasciicircum}2\$ and \${\textbackslash}pm6500\$ km/s range in
velocity. We obtain a robust sample of 46 CO(1-0) detections spanning
\$z=2.09-2.22\$, constituting the largest sample of molecular gas
measurements in protoclusters to date. The CO emitters show an
overdensity at \$z=2.12-2.21\$, suggesting a galaxy super-protocluster or
a protocluster connected to large-scale filaments with {\textasciitilde}120 cMpc size.
We find that 90\% CO emitters have distances \${\textgreater}0'.5-4'\$ to the center
galaxy, indicating that small area surveys would miss the majority of
gas reservoirs in similar structures. Half of the CO emitters have
velocities larger than escape velocities, which appears gravitationally
unbound to the cluster core. These unbound sources are barely found
within the \$R\_\{200\}\$ radius around the center, which is consistent with
a picture in which the cluster core is collapsed while outer regions are
still in formation. Compared to other protoclusters, this structure
contains relatively more CO emitters with relatively narrow line width
and high luminosity, indicating galaxy mergers. We use these CO emitters
to place the first constraint on the CO luminosity function and
molecular gas density in an overdense environment. The amplitude of the
CO luminosity function is 1.6\${\textbackslash}pm\$0.5 orders of magnitudes higher than
observed for field galaxy samples at \$z{\textbackslash}sim2\$, and one order of
magnitude higher than predictions for galaxy protoclusters from
semi-analytical SHARK models. We derive a high molecular gas density of
\$0.6-1.3{\textbackslash}times10{\textasciicircum}\{9\}\$ \$M\_{\textbackslash}odot\$ cMpc\${\textasciicircum}\{-3\}\$ for this structure,
consistent with predictions for cold gas density of massive structures
from hydro-dynamical DIANOGA simulations.},
