  We report the detection of a $\gamma$-ray bubble spanning at least 100$\rm
deg^2$ in ultra high energy (UHE) up to a few PeV in the direction of the
star-forming region Cygnus X, implying the presence Super PeVatron(s)
accelerating protons to at least 10 PeV. A log-parabola form with the photon
index $\Gamma (E) = (2.71 \pm 0.02) + (0.11 \pm 0.02) \times \log_{10} (E/10 \
{\rm TeV})$ is found fitting the gamma-ray energy spectrum of the bubble well.
UHE sources, `hot spots' correlated with very massive molecular clouds, and a
quasi-spherical amorphous $\gamma$-ray emitter with a sharp central brightening
are observed in the bubble. In the core of $\sim 0.5^{\circ}$, spatially
associating with a region containing massive OB association (Cygnus OB2) and a
microquasar (Cygnus X-3), as well as previously reported multi-TeV sources, an
enhanced concentration of UHE $\gamma$-rays are observed with 2 photons at
energies above 1 PeV. The general feature of the bubble, the morphology and the
energy spectrum, are reasonably reproduced by the assumption of a particle
accelerator in the core, continuously injecting protons into the ambient
medium.
