In the next few days, Lu Feng let the army try to attack twice, and the best result was on the city wall, but before he could gain a foothold, he was already shot down by the bed crossbow.

In the end, a lot of soldiers were lost, but the walls were not yet taken.

This also made Lu Feng very helpless.

However, in the past few days, Xun Yu and Jia Xu have taken people to explore around Qiushan City and find a way to break the city.

"Your Majesty, the minister has a plan!"

On this day, in Lu Feng's military tent, Xun Yu ran in with excitement on his face.

Lu Feng's face was overjoyed, and he hurriedly said, "Wen Ruo, come, tell me quickly, what plan do you have?"

"Your Majesty, these days, Wen He and I have taken people to explore the terrain around Akiyama City, and we have found something outside the south gate!"

"What discovery?"

"Your Majesty, the south gate of Akiyama City is Akiyama, but because the soil in that place is loose and the city wall is not very strong, it is normal for things to collapse, if we attack with water, we will definitely be able to break through the city gate in one fell swoop!" Xun Yu said.

Lu Feng frowned slightly, and asked, "Water attack, Qiushan City is half a day's journey from the Jade Snake River, and we have to pass through Xiaolingdu halfway, how can we attack by water?"

"Your Majesty, don't worry, I've found the water for the water attack!" Xun Yu said with a smile.

"Where?"

"On the autumn mountain behind Akiyama Castle, there is a waterfall, very large, straight into the Jade Snake River, but we can intercept the flow, we only need to bring the water of this waterfall over, soak the south gate of Akiyama Castle, within ten days, the south gate will be broken, Akiyama Castle will be broken!"

Lu Feng listened, groaned slightly, and said: "There is no reason why Zhang Pengyi and Hou Lin in Autumn Mountain City should not know this, after all, they have been in Autumn Mountain City much longer than us, they should have taken it into consideration!"

"Your Majesty Mingjian!"

Xun Yu said: "As Your Majesty said, when Wen He and I were investigating the place, we saw the soldiers of Akiyama City, and they also noticed the waterfall, but there was no way to stop it, so we could only keep the waterfall!

"At this time, anyone can interrupt our plans as long as there is a sneak attack. So ......"

"Cavalry!"

Lu Feng took over and said, "Let the cavalry gather outside the south gate, once the soldiers in Qiushan City attack, there will be no mercy!"

Xun Yu nodded and said, "Your Majesty, Wen He and I also think the same way, this method is our only way at present, you can give it a try!"

"Okay, let's do it according to this method, inform Lu Bu's cavalry to get ready, and at the same time divide an army of 50,000 and start breaking ground!"

Xun Yu answered and immediately went down to make arrangements.

With an order, the 50,000-strong army quickly assembled, and under the leadership of Lu Feng and a few people, went to dig a channel.

When these people arrived at the waterfall and had just broken ground, the people arranged by Zhang Pengyi and Hou Lin had already sent the news back.

Zhang Pengyi and Hou Lin immediately met.

"Brother Zhang, you also got the news, what are your plans?" Hou Lin's face was heavy and he looked at Zhang Pengyi.

Zhang Pengyi's face was also not good-looking, and he naturally knew the threat of the waterfall to Qiushan City, but there was no way to solve it.

"Send troops to attack, you must not let this channel be dug up by Lu Feng!" Zhang Pengyi said in a deep voice.

Hou Lin smiled bitterly and said: "I have already received the news, Lu Feng in order to prevent us from sending troops, Lu Bu is waiting outside with 30,000 iron horses, if we open the city gate, I am afraid that before we can rush out, Lu Bu iron horses have already rushed in!"

Zhang Pengyi's face became even more ugly, he groaned slightly, and said in a deep voice: "The army has withdrawn into the inner city!"

"Retreat into the inner city?"

Hou Lin was taken aback, stared at Zhang Pengyi, and said: "Brother Zhang, this matter is not to talk about, once you give up the outer city, although the inner city has strong walls and thick walls, there is no chance to break through, you have to think clearly!"

Zhang Pengyi smiled bitterly and said, "Why don't I know? I just know what can I do? Could it be that we are waiting here for Lu Feng to release water to soak the South Gate, so that the South Gate City will collapse, and wait for the army to come in?"

"Withdraw into the inner city, we can fight a protracted war with Lu Feng, the military food in the inner city is enough for our army to eat for a year, and Lu Feng's army has come from afar, and the military food will definitely not be able to keep up!

Hou Lin sank slightly, looked up at Zhang Pengyi, and said in a deep voice: "Brother Zhang, have you already decided?"

Zhang Pengyi nodded and said, "I have made up my mind, Brother Hou, if you are not willing to do this, you can lead your 100,000 troops to continue to hold the outer city, and I will lead the army to hold the inner city!"

Hou Lin smiled bitterly, if Lu Feng forcibly attacked regardless of the life and death of the soldiers and the losses, the 200,000 army might not be able to hold Qiushan City, let alone the 100,000 army.

He nodded, agreed to Zhang Pengyi's suggestion, withdrew into the inner city, and fought a protracted battle with Lu Feng.

However, although it is a decision, the withdrawal of troops is also a science, once Lu Feng sees the clue and the army is attacking the city, then everything will be over!

Under the arrangement of Zhang Pengyi and Hou Lin, the army withdrew into the inner city in an orderly manner, leaving only 20,000 people on the city wall with banners, making it look like the army was still there.

On Lu Feng's side, the army continued to dig channels, and two days later, the channels were finally about to be dug through, and the south gate of Qiushan City was broken, just around the corner.

"Your Majesty, news has come from Jinyiwei that there is movement in Akiyama City. ”

Just when Lu Feng was about to order the last section to be dug through, Jia Xu came to his side, his face a little ashamed.

Lu Feng looked at it and said with a smile: "Wenhe, what's wrong with you, your face is so ugly!"

"Plop!"

Jia Xu suddenly knelt on the ground and said, "Your Majesty, the minister is incompetent, and he failed to get the first information about the actions of the army of Akiyama City, and I hope that Your Majesty will be punished!"

Lu Feng frowned and asked, "What the hell is going on?"

Jia Xu handed the letter from Jinyiwei to Lu Feng.

After Lu Feng saw it, his face was cloudy, and after a while, he sighed and said, "It seems that we still underestimate this Zhang Pengyi and Hou Lin's determination to defend the city!"

Zhang Pengyi and Hou Lin's army retreated into the inner city, and they retreated yesterday, but Jinyiwei only found out about the situation this morning.

This is the dereliction of duty of Jinyiwei.

Jia Xu is the commander of the Jinyi Guard, and this matter is inseparable, so he is pleading.

Looking at Jia Xu, Lu Feng helped him up and said with a smile: "Wenhe, although this is a dereliction of duty on the part of Jinyiwei, the responsibility is not on you, after all, even I didn't expect that Zhang Pengyi and Hou Lin would completely give up the idea of breaking through and lead the army to retreat to the inner city!
