This is the key factor that Guan Yu is struggling with in his heart at this moment.

If he didn't know the letter before setting off, he might have started deploying a battle plan to attack the city without hesitation.

"Yes, I am worried about the safety of the rear."

Guan Yu once again scanned the generals with his eyes, and then cut to the chase and said, "If we launch a strong attack at this moment, Xiangyang will be in danger and receive a steady stream of reinforcements from the Cao family."

"Then a big war will definitely break out in Xiangfan."

"This battle will also become a see-saw, and it will never end easily. But if Sun's troops attack the rear at this time, what should our army do?"

After saying this, Guan Yu's red eyes opened slightly, his expression became more solemn, and he said loudly:

"Xiangyang has a favorable geographical location. It is not easy to attack by force!"

"Xiangfan, Xiangfan, if you want to conquer Xiangyang, you must first capture Fancheng."

"But Fancheng is located on the north bank of Mian River, and its strategic location is more important to the Cao family than Xiangyang."

"As long as I issue a battle plan to capture Fancheng, Cao's army will come to the rescue at all costs."
