As the passage appeared, a chorus of gasps echoed around.
When Ye Fei had gathered his strength and punched, no one had sensed any energy fluctuations. However, the fact that his punch had created such a massive passage through space that even a master like Tang Qinghe couldn't break was self-evident.
It was similar to the battle between Zhao Zichen and the black-robed figure; no energy fluctuations were detected. It seemed their control over energy was far beyond the imagination of the onlookers.
No wonder Zhao Zichen had said Ye Fei's strength was at least on par with hers.
As for who was stronger between Ye Fei and Zhao Zichen, it was beyond the comprehension of the Great Perfection cultivators present, despite being the top cultivators in the True Emptiness Realm.
Only Zhao Zichen knew the truth.
