Kapitel 933: Dao Ancestor: Do You Think There's No One on Earth? (1)

Explosions rose and fell in the sky. Su Yun looked up in puzzlement and saw that the mechas in the sky had formed a defense line. They kept pouring fire to stop the two oval-shaped aircraft.

Great Xia's Xuanwu Fighter and Luan Fighter were in the lead. Technological warships of various sizes followed closely behind, constantly chasing after the oval-shaped aircraft to attack.

Su Yun's gaze quickly landed on the two high-speed flying vehicles. With just a glance, Su Yun immediately determined that they were not Earth's technology. Even the Xuanwu Fighter and the Luan Fighter's highest speed was only 4,523 kilometers per hour.

The highest speed of the intercontinental missile was 2.52 kilometers per hour. Even if it was an artificial flying object that had escaped Earth's gravity, its speed was only about 30 million kilometers per hour.
