Zhang Tie flew in the upper region of the stratosphere over 60 miles above the sea in Chaos at a high speed...
Zhang Tie had played his flight ability as a divine dominator to the utmost at this moment and reached 8 times the speed of sound in the air, namely about 2,800 m per second and almost 6,000 miles per hour.
A few months ago, when he had just developed the flight ability as a divine dominator in Xuanyuan Hill, he could at most reach 6 times the speed of sound in the air; however, after killing Han Zhengfang and Han Yuanhong, Zhang Tie promoted to the 4th realm of earth knight and gained a higher overall strength; especially after absorbing the spiritual energy of both Han Zhengfang and Han Yuanhong, Zhang Tie's spiritual energy bulged as he gained a greater flight ability as a divine dominator. He could fly at 8 times the speed of sound in air; actually, almost 9 times the speed of sound.
