In anger, two Ming soldiers climbed up the hill carrying new flags.

Soon, the top of the earthen hill was covered with flags again.

"Your Highness, it seems that the Ming army has started working again!" said Bolo, the Doroberel of the Zhenglan Banner.

Hauge lowered his head and said nothing.

"Your Highness, there is a situation with the Ming army!" Bolo raised his voice.

Hauge still didn't speak.

"Your Highness..." Bolo reminded again.

"Shut up!" Hauge said angrily, "I am not blind, I can see it."

"Then shall we... fire?" Bolo asked.

"Fire your ass!" Haoge cursed. "The Ming army is using flags as bait. There is no one on the hill! If we fire now, they will only lose some flagpoles, while our army will waste a lot of gunpowder and shells. It's not worth it!"

"But..." Bolo was a little helpless, "The Ming army is hiding behind the flag. What's true and what's false? What if there's someone behind the flag?"

Hauge gritted his teeth and said, "Well said, what if there is no one behind? Our artillery is used to kill people, not to blow up flags. Unless we are sure there is someone behind the flag, we cannot fire."

Bolo took up the telescope and looked for a while, then said worriedly, "Your Highness! The flags on the opposite hill are too dense, and we can't see the situation inside. If we give the Ming army enough time, they will be able to pile up earth hills and set up red cannons to bombard Ningyuan City!

"Let's bomb them!" Hauge seemed to have accepted his fate. He pointed to the earthen hills on the south bank of the Ningyuan River and said, "The Ming army is piling up earthen hills there. Although they haven't finished yet, they will succeed sooner or later! We can stop them for a while, but we can't stop them forever."

"Since you can't change it, just face it calmly!"

"Hey!" Bolo sighed and suddenly looked up at Haoge: "Prince, how about... we also dig soil and build a mountain?"

"It's a waste of effort!" Hauge shook his head. "Our army doesn't have many artillery pieces and is powerless to fight against the Ming army."

"Then...how to defend Ningyuan City?" Bolo's tone was a little flustered.

"Why are you panicking?" Haoge glared at him fiercely. "The Ming army hasn't even attacked the city yet, and you're panicking. How can this be known to others?"

Bolo lowered his head and said nothing more.

At this time, several more shots were fired from the city wall, and the shells fell near the earthen hill blocked by the flags and disappeared.

Since they could not see the Ming army, the defenders on the city wall could not aim and had to stop firing.

The Ningyuan city wall returned to silence.

Before walking down the city wall, Hauge gave an order: "If nothing unexpected happens, the Ming army will be able to complete the work in a few days, and then they will fire at our camp on the north bank across the river."

"Order all units to withdraw their camp three miles north to prevent being bombarded by the Ming army!"
