Li Mu originally thought that the Goguryeo king Bogu would lead his troops to withdraw from the domestic city and flee south to the Chaoxian Peninsula, so he ordered the Flying Leopard Legion to ambush at the western foot of Gaima Mountain one step in advance.

After capturing Shuoji City, on the way north of the Liangzhou army to the domestic city, Li Mu received news from Tanma...... The Goguryeo people were busy fortifying the walls and clearing the wilderness, mobilizing the tribes to strengthen the city defenses.

"Command the army to encamp!"

But listening to the military information from the horse, Li Mu already had a strategy to break the enemy.

"Bogu tried in vain to hold on to the domestic city, and he really didn't know whether he was alive or dead. He thought that he could defend the city by clearing the wilderness and strengthening the city defense, but it was really wishful thinking! ”

Pang Tong, who knew in his heart, said loudly with a smile on his face: "This time, the Goguryeo tribe will definitely be wiped out by our army."

"In Shiyuan's opinion, what strategy should be used to break the enemy?" Li Mu looked in the direction of the domestic city, with a smile on his face.

"The lord already has a plan to destroy the enemy in his heart!"

Pang Tong, who had already been a bamboo in his chest, first laughed, and then told his thoughts eloquently, "Ma Zishui originates from the Gaima Mountain, flows from the northeast to the southwest, flows through the domestic city, and then enters the sea (Yellow Sea) in Xi'an Ping."

According to the local villagers, in late July every year, there must be heavy rain. Our army can pretend to set up camp here, so that the elite infantry cavalry will make a detour to the north of the domestic city, and stop the water and build a dam in the upper reaches of the Mazi River.

When the heavy rain comes, dig the embankment and flood the domestic city, and overnight, the Goguryeo tribe will be wiped out! ”

Li Mu nodded with a smile, he and Shi Yuan really thought of it.

"Once the domestic city is flooded, there are two ways for the enemy to flee: first, flee to the Chaoxian Peninsula along the line of Gaima Mountain; Second, he fled south to this place. ”

Pang Tong added again, "Just in case, the lord can order Gongming to divide his troops to defend the west of the inner city, and drum up the momentum, thinking that it is a suspicious plan." ”

In the past, the Liangzhou army had used the strategy of "flooding the city" more than once, but it was just pretending to be and did not implement it, just because it took care of the Chinese people in the city.

But now it is different, in the face of the Goguryeo people in the domestic city, the Liangzhou army will not have the slightest concern, let alone a little pity.

"What Shi Yuan said is exactly what I want!"

Li Mushen said loudly with approval: "I should personally unify the army to the north, and Shiyuan will stay here to cut off the retreat of the Goguryeo tribe."

"When the lord goes north, he should put his own safety first!"

Pang Tong gave a salute, his expression was full of solemnity, and his tone was full of solemnity: "Youtong stays here, and the Goguryeo people don't want to escape."

"Evil, you cooperate with Shiyuan to stay here, and you must protect Shiyuan."

Li Mu said in a solemn voice: "Shiyuan, but there is a slight mistake, I am the only one who asks!"

"Rest assured, my lord!"

Dian Wei hurriedly gave a salute, and said solemnly: "Wei Ding will protect Shiyuan!"

After everyone said goodbye one by one, Li Mu, Fu Yan, Zhao Feng, Gao Xiang, Huang Xu, and Gan Fu were six handsome Longxiang cavalry, Vermilion Bird cavalry, and 20,000 infantry of the Tiger Wing Army, heading towards the upper reaches of Mazi Water.

Pang Tong, Dian Wei, Yan Yan, and Jiang Jian commanded the remaining 30,000 cavalry, set up camp, and cut down trees to make rafts.

After receiving Li Mu's military order, Xu Huang, who ambushed Xu Huang at the western foot of Gaima Mountain, ordered Pan Feng and Zhang Yi to take 20,000 steps to ride... Crossing the horse water in the west, in the mountains to the west of the city set up a continuous camp.

…………

Pegu, who was unwilling to abandon the domestic city, transferred tens of thousands of Goguryeo people around the domestic city... All of them were recruited into the city, and they were forced to repair their armaments and arrange the city's defenses.

Since the military meeting in the palace, Baqi, Youju, Yiyimo and others have entered the palace several times to admonish, but they have not seen Bogu himself.

Baqi and Yiyimo couldn't abandon Bogu and the Goguryeo people, so the brothers could only guard the city wholeheartedly.

In the evening of the seventh day, the clouds were overcast and the air was filled with moisture, which was obviously a sign of heavy rain.

"Your Royal Highness, the water in the north of the city has been cut off."

"How can a good gamble be cut off?"

At this moment, Yi Yimo rushed over, "Brother Wang, the water in the east of the city suddenly cut off, I don't know why?" ”

The water flows through the east and north of the city, and the water of the people in the city is introduced into the city from these two directions.

"How can such a big river be cut off so easily?" Youju was puzzled and groaned.

"Yes, this year is not a year of great drought, and it is impossible for Mazi water to be cut off for no reason." Toyetie stroked his long hair, also confused.

After seven or eight breaths......

"Suffered!"

When the inspiration flashed, he was shocked and exclaimed, "There must be enemy troops in the upper reaches of the horse!" It must have been the enemy who cut off the water in Mazi! ”

"Brother Wang, how should this be?"

"Your Highness...... What to do? ”……

But listening to what Baqi said, Yiyimo and the Goguryeo civil and military forces were almost scared to death on the spot.

"For today's plan, let's send someone to the upper reaches of Mazi Water to investigate."

Baqi's heart was beating like thunder, and the whole person was already panicking, "I should go into the palace to meet the king, Chen Li, and organize the people to withdraw from the domestic city as soon as possible, and it will be too late to change and regret it!" ”

That's it!

The wind is blowing, the lightning is thundering!

Immediately afterward, the torrential rain plummeted!

It's just a dozen breaths of time, and between the ground, there is a vast expanse of white, and within three steps, there is no human figure.

It is already impossible to send troops out of the city!

Baqi, Yiyimo, Youju, and Toyatie could only brave the torrential rain and rush to the palace as if they were dying.

It was only a quarter of an hour for Baqi and the others to arrive at the palace, and in this short period of time, the water in the city was three feet deep.

This time, Baqi, Yiyimo and others met Bogu smoothly.

At this time, Bogu was obviously frightened by the rainstorm, and hid in the dormitory in fright, and he had already been unintentionally frolicking.

Baqi hurriedly saluted, and reported the speculation that "the enemy army cut off the water in Mazi" and the fact that the water in the city was accumulated.

But listening to what Baqi said, Bogu was so shocked that his soul did not possess his body; Now, with the heavy rain, if the enemy army really floods the city, it is not even whether they can survive, and even whether the city can exist is unknown.

"What do you do now?"

Under the panic, Bogu was already a master of the six gods, he was not a talented monarch in the first place, how could he have encountered such a grim situation?

"In my humble opinion, once the torrential rain stops, the enemy army will inevitably take advantage of the situation to flood the city, and we should withdraw from the city before the enemy army digs the embankment."

Baqi saluted again, and said anxiously: "The Gaima Mountain in the east is enough to garrison troops to take shelter temporarily. Please give the order quickly! If you hesitate any longer, it will be too late to regret! ”

"Great King, according to the news from our army scouts, in the mountains west of the city, the enemy army has a company camp of more than ten miles."

Youju said anxiously: "Now, I can only retreat to Gaima Mountain." Please don't hesitate any longer. ”

After a dozen counts......

"It's raining too much, what can I do?"

Bogu shook his head again and again, "It's better to ...... Wait for the rainstorm to pass before retreating. ”

"Father! Can't wait any longer! ”

"The King...... Hurry up and give the order! ”……

Baqi, Yiyimo, Youju, Toyetie, Miansang and others hurriedly knelt on the ground, begging and begging again and again.

Bogu still did not agree to withdraw his troops, to be exact, he was frightened by the torrential rain in front of him.

Baqi and Youju people, kowtowed and persuaded for a quarter of an hour, but Bogu never let go; The crowd left the palace with their faces as if they were dead, and went to evacuate the people and dredge the floods.
