History
After Varrick had refused to work for Kuvira and destroyed his destructive invention, Kuvira ordered Bataar Jr. and Zhu Li to recreate the weapon and to bring it to working order as soon as possible. For the workplace for the superweapon, an already existing re-education facility was converted. Below the main hangar, in which the superweapon was housed lied a large cavern, in which the Beifong family was kept.

After learning the whereabouts of the location by Bolin, Lin, Toph, Opal and Bolin travelled on Juicy to Kuvira's secret factory. As they arrived, Opal went ahead to scout the surrounding area, and found out, that Zhu Li had been on their side the whole time, trying to sabotage the deadly superweapon on numerous occasions and was sentenced to be the weapon's first victim.

At the same time, Bolin, Opal, Lin, and Toph arrived at the facility to free their family. After using her seismic sense, Toph found out, that their family was held in an underground bunker. The strike force managed to get to the prison chamber unnoticed, and managed to free everyone except Suyin and Baatar, who was afraid to go out of the cage as it dangled several tens of feet from the air. After Bataar screamed in fear when he was thrown to Bolin, the guards became suspitious and saw the escape attempt. They sounded the alarm, which gave out their position. The group managed to get out of the underground cave and hid in a secluded part of the facility. As Opal joined them, she told them what was to happen to Zhu Li. As the others were determined to try to stop Kuvira for good, Bolin and Opal flew on Juicy to save Zhu Li.

As Opal and Bolin managed to get to the abandoned city, which was chosen as a test site for the weapon before it could be fired, the Beifongs (all except Toph, who was guarding Bataar and Huan) attacked the giant cannon and dislocated it's trajectory, which caused the cannon to miss its target. As the battle waiged on, everyone except Suyin was batteling Kuvira's forces on the ground, while Suyin was fighting with Kuvira onboard the cannon. As they grew evermove tired they retreated and formed a stone circle armound them for protection. As Kuvira's army was at the verge of victory, Toph showed up, and with a swifth move destroyed several Mecha tanks. Then, Opal, Bolin and Zhu Li arrived on Juicy and managed to load the Beifongs onto the flying bison and fly away.
