Through the porthole beside him, Zhang Tie saw airships covering the sky, causing a colossal dark shadow; he felt shocked at the scale of the operation.
These actions further displayed Huaiyuan Palace's power to Zhang Tie.
After forming a matrix in the air, two groups of airships covered thousands square meters in the air.
Thankfully, it was evening. If such a swarm of airships passed by in the daytime, the wide area of black shadow would bring an extreme sense of fear to people on the ground.
They boarded the war airships which were built for Huaiyuan Prefecture's troop last year. They were as long as 400 m and weighed more than 300 tons. They could navigate 4500 km at a speed of 160 km/h one time. Therefore, they were qualified to be known as the kings of the skies.
Being different from the cigar-shaped airships that Zhang Tie took before, the triangular shape of the war airships looked extremely like a ray in the sea while its huge body afforded it a super large capacity.
