Chapter 404: 404

A four-meter-tall humanoid robot appeared next to Xuan after his words. This robot had been standing in this darkness. Its eyes lit up and a very faint light glowed on its body.

The robot took a heavy step and jumped about ten meters. Its body bended backward as it began a transformation. In just a second, the robot transformed into a jet fighter with a streamlined body.

They could hear a cry of excitement coming from the jet. Two streams of electricity burst out from its back. The plane sped toward the weapon testing center. Once it reached within a hundred meters, it fired several mini missiles from the wings. The missiles bombed the exterior walls. The concrete was blasted in the explosions. There was another cry coming from the jet. The jet flipped again as it landed and turned into a walker type.
