"Mr. Wen is right!"

Hearing Li Ru's advice, She Fu nodded in agreement.

Just as the two were talking, the messenger sent by Murong Tu also found them.

"Greetings, Lord Shefu! Young Master Wenyou, my chieftain has specially dispatched me to inquire about the progress of your siege!"

Shefu shook his head with a solemn expression: "Daqing Military Town has high walls and thick fortifications, making it extremely difficult to breach. The Han army is like wild bulls, with inexhaustible strength, and our army has suffered heavy casualties!"

"But...why didn't I see any of your soldiers' bodies?"

Looking at the clean and tidy appearance under the north gate, the messenger couldn't help but ask with a puzzled expression.

"The moat has been filled in!"

After saying that, Shefu turned and left with an impatient look on her face.

The soldier paused for a moment, glanced at the filled-in moat, but had no intention of going over to check it, so he turned and left.

Upon learning that the situation was the same on the Wuhuan side, Murong Tu fell into deep thought.

"If we attack the leader, are we still fighting?"

One of Murong Tu's personal guards couldn't help but ask.

"Let's call it a day and see what happens tomorrow!"

Once he came to his senses, Murong Tu glanced at the guards on the city wall and then ordered a retreat.

"Damn it, what's going on? Why aren't the Xianbei fighting anymore?"

"Exactly! We finally got to have some fun, and then they just pulled away?"

"Pah! A bunch of spineless cowards!"

Seeing the Xianbei army suddenly withdraw, the soldiers who had just been replaced to defend the city couldn't help but curse with resentment.

That night, Murong Tu sent men to invite Li Ru and She Fu into his tent.

“Mr. Wenyou, I feel something is amiss during today’s siege. Our army attacked the city three times in a row, lasting for nearly two hours, but the Han soldiers not only did not appear tired, but became even more courageous. What is the reason for this?”

As soon as he sat down, Murong Tu couldn't wait to tell Li Ru about his doubts.

Li Ru pondered for a moment, then said, "If I am not mistaken, the garrison in Daqing City should be more than those on the city walls. It seems that they took turns guarding the city while our army was retreating."

Furthermore, the Han army's armor and weapons were all identical, making it impossible for our troops to distinguish them.
