Ling Tianxue was indeed correct in her thinking; the current strength of Ling Tianyu had reached a terrifying level. In the span of over three years, aside from two months of restrictions, Ling Tianyu had been making breakthroughs incessantly.
In Crow Ridge City, the attacks were still ongoing without any signs of breaching the city, day in and day out, through the passing of all four seasons—spring, summer, autumn, and winter—never ceasing.
Ling Tianxue, Su Ziyang, and the others guarded here, with no movement at the entrance and exit, it was apparent that they had yet to be discovered, resorting solely to brute force to attempt a breakthrough.
Compared to the Emperors, they were far inferior; at least others could find a way out. The three of them just blindly attacked, not using their brains at all.
This was actually beneficial, as it gave Ling Tianyu more time to break through.
