Are you kidding me? The Yan army has hundreds of thousands of troops. Even if they sneak into the camp by chance, there is no reason that they can escape unscathed after blowing up the gunpowder magazine!

If Han Du hadn't confirmed that Zhu Di's gunpowder magazine had been bombed last night, Han Du would have doubted whether Zhu Di was playing a double act with these people.

"Thank you for your hard work. Let's all go down and rest. You won't have to fight in the future battles."

Although Han Du was full of doubts, he said nothing. He smiled and waved for everyone to leave.

Xu Chengfei also smiled and said, "Congratulations on coming back alive. Don't worry, my father-in-law doubled your reward last night. It was originally intended for your family. Now that you are back, you can take away the reward at any time."

"

"Thank you, sir, thank you, sir!"

When everyone heard that the reward had been doubled, they were all surprised and quickly bowed.

After everyone left, Han Du looked strangely thinking.

"What's wrong? What are you thinking about?" Xu Chengfei stood directly next to Han Du and asked with a faint smile.

Han Du glanced at him, shook his head and chuckled, "I don't believe you didn't notice something strange. Ten people can come and go freely in the Yan Army camp. Do you think this is possible?"

Xu Chengfei pondered for a moment, "It's not impossible. If they plan their retreat in advance and take advantage of the explosion before the Yan army can react, it's not impossible to escape."

"It just requires luck!" Xu Chengfei added at the end.

Han Du shook his head and chuckled, luck? Where can there be so much luck in this world?

The so-called tone is all carefully woven by thoughtful people!

However, Han Du did not continue talking, knowing that Xu Chengfei also knew that there must be something weird in this.

For three consecutive days, the Yan army did not attack the city again. It seemed that the explosion that night caused great losses to the Yan army. It may also be that the Yan army lost the cannon and no longer had the courage to attack Xuzhou City.

Just as Han Du was humbly learning from Geng Bingwen his experience in defending the city, Guo Ying strode in.

He said with surprise on his face, "Commander, the Yan army has retreated!"

Han Du suddenly stood up and asked, "Did you really retreat?"
