"Because at the beginning of constructing the Tianhe defense line, your father and the former emperor had already built a large number of formation patterns and equipment for counter-attacks and crossing the Tianhe. The Sect Alliance occupying the south of Tianhe for only a month simply did not have time to build corresponding fortresses. Caught unprepared, they couldn't possibly hold it."
At this point,
Feng Yuanqin paused slightly in his tea pouring:
"In other words, only after Li Qingyan crosses the Tianhe will the Hongnong battle officially begin."
Xu Yuan raised his brows and looked up:
"Grandfather still knows military strategy?"
Feng Yuanqin grinned proudly:
"In the past, which head of a great family in Dayan has not been to the battlefield?"
Xu Yuan thought it was indeed the case.
