The branches and leaves are dead, the leaves are falling everywhere, and the land is desolate.

Lu Xun endured the pain in his body and wrote something beside the bed.

While writing, Lu Xun kept turning and said: "Finally, the day has come. The prosperity and decline of me, Lu Xun, and the Lu family depend on your writing!"

His son Lu Yan, while blowing the medicinal soup, looked over and asked: "Who is father writing to?"

Lu Xun pointed to the five words on the far right side of the letter - personally signed by General Lu.

He opened his mouth and said: "Write to General Lu Menglu..."

"Can he save his father?"

"Only he can save the Lu family!"

"But will he save me?"

At this time, Lu Xun sighed: "Lü Meng and Lü Ziming used to be ridiculed as 'Amen under Wu'. From then on, he read military books at night. Now he talks about the art of war and talks eloquently. 'Three days of farewell' to the Lord's ministers.

His filial piety towards his mother is known throughout the country... Even Lu Zijing and Gan Xingba worship their mother..."

"In addition, he is also magnanimous. He is loyal to his colleagues and helps Xu Gu and others raise orphans. He is also magnanimous and does not care about his personal grudges with Cai Yi and Gan Ning. Instead, he speaks favorably for him before the Lord... Such a person

, I'm sure I won't make trouble, and will tell Wu Hou everything here truthfully, and Chen Ming's divine arrow that day will also give us a way to survive, right?"

At this time, a guard came in and said, "General Lu, Madam...Madam, she...she is missing."

Hearing such words, Lu Xun felt very calm. He sighed: "Madam still can't trust Wu Hou..."

"Where did mother go?" Lu Yan asked.

"This is not the first time she mentioned that she wanted to join Jingzhou. She mentioned this to me again last night, and even proposed that she would go to the front station, but I refused." Lu Xun's eyes were filled with emotion.

have no choice.

"Why not?" Lu Yan couldn't understand.

"Because...because, cough cough cough cough..." After a violent cough, Lu Xun opened his mouth lightly: "Once, once you really vote for Jingzhou, then the Lu family will be a 'floating family', living under the fence of others, without roots...

"

Lu Yan gritted his teeth. It was rare that he was willing to support his stepmother this time.

"It's better to have no roots than to have no life, right?"

After a while, another guard came in and said eagerly: "General Lu, Madam... Madam is heading northwest towards Changsha."

"It's not in the direction of Changsha, but in the direction of Jiangling..." Lu Xun looked gloomy, still without any surprise. He slowly collected the bamboo slips, "Yan'er, go in person and deliver this letter to General Lu Ziming..."

"Father...I..." Lu Yan stopped talking.

The implication was that he was obviously worried. He said in panic: "What if I am taken hostage by Lu Meng?"

Lu Xun was still scrolling the picture silently. He looked at the five characters "personally signed by General Lu" on the letter with eagerness and sadness.

Who would have thought that he, Lu Xun, would be humble and cautious for more than ten years, and that every step he took would be like walking on thin ice.

But in the end...

His life and that of the Lu family were actually in the hands of others.

sad…

How sad?

At this time, a notification suddenly came from outside the door.

"General Lu, there is a man from Changsha outside the door. He claims to be Han Xuan, the former governor of Changsha. He wants to see the general..."

This voice just came out.

Lu Xun seemed to be excited all of a sudden.

"not see--"

He screamed hard.

"Let him go, let him go, no, catch him...lock him up!"

As if worried, Lu Meng and Sun Quan would misunderstand him even more.

Lu Xun was in an extremely nervous mood, and his cheeks were filled with sorrow.

Even God seemed to feel the sadness in Lu Xun's heart.

The strong wind swept the dark clouds, and deep in the dark clouds, there was a goose...

Yan Na - you should grow some snacks!

…

…

Even though it was already dark, Guan Lin, Hao Zhao, and later Mi Fang were all in great spirits.

A drawing of the new city of Gangneung City is spread out on the stone steps above the city gate.

The surrounding soldiers lit their torches.

Facing the drawing, Hao Zhao was talking eloquently, "The purpose of building the new city is that when the enemy attacks Jiangling, they need to attack the city twice, which is twice the difficulty. But if you follow the same principle, it will take four times the effort."

Difficulty, you only need to add a city wall outside the new and old cities. In this way, the old and new cities, the old and new walls... When the enemy attacks the city, it doesn't matter if the outer wall is broken. The whole army can retreat to the inner wall.

If the inner wall is broken, the enemy will retreat into the new city. When the enemy attacks the new city, they will encounter the inner and outer walls, which is equivalent to attacking a city four times."

Hao Zhao's explanations are getting better and better.

He drew a circle on the periphery of the new city design, pointed to the gap between the inner and outer city walls, and continued to talk, "I have been in the army for several years and learned many city defense techniques from General Wenpin.

The most lacking thing in defending a city is actually not troops, but military supplies, but supplies... Often in a real city defense battle, more than half of the troops have to transport arrows, stones, and weapons!"

"As long as these military supplies are sufficient and the enemy sets up ladders, they can shoot with sufficient fire arrows. The ladders will burn and the enemy will naturally be unable to climb up; and the enemy will attack the city with chariots, without the need for huge rocks, as long as the defenders prepare them in advance.'

The big rope' and the 'stone millstone', use the big rope to tie the 'stone millstone' and smash it down, no matter how hard the punch is, it will all be broken!"

"So... the supply of ordnance is a top priority, and the arsenal in the city is too far from the city tower. Facing the enemy's surprise attack, I temporarily mobilized... There was no time, so a large number of troops and horses were wasted. This is why we have such internal and external problems.

With the design of two cities and two inner and outer walls, an arsenal can also be built in the middle to store the ordnance needed to defend the city..."

Speaking of this, Hao Zhao paused for a moment and continued to talk, "If the enemy uses the well railing as a cover and then builds trenches to protect the city, then don't be afraid, because the well railing can break the outer wall, but the

If you can't get through the outer wall, let alone attack the inner wall, this second line of defense is far stronger than the first line of defense."

"In addition, you can also dig deep ditches in the inner and outer city to intercept the enemy's tunnel offensive of the Digging Army and expose it... Calculated in this way, actually siege the city is still four times as difficult as

Conservatively, it takes four sieges to capture a city, and the most difficult one will be six or eight times the original! A compound road can also be added between the inner and outer walls according to the design of the old and new cities for daily convenience.

Passage, road closure during wartime..."

After saying this, Hao Zhao turned back to look at Guan Lin and Mi Fang.

Guan Lin exhaled a long breath, feeling inexplicably more at ease in his heart.

He is worthy of being the leading city defense master. Historically, the design of Guan Yu's old and new cities has been "unprecedented". However, Hao Zhao added two inner and outer walls on this basis.

The old and new cities, the inner and outer walls;

Four times... No, it's not four times at all. This is the incremental method. Attacking the city will be eight times more difficult, and defending the city will be eight times more fun!

Guan Lin couldn't help but sigh in his heart:

——"Hao Zhao, Hao Zhao, you force me to admit that many things require talent, and in many fields, geniuses exist!"

With this in mind, Guan Lin looked at Mi Fang.

"Second brother? What do you think?"

Mi Fang scratched his head and made an expression like "I don't understand, but I'm shocked." He pursed his lips and sighed: "Okay, it's good, but...it's equivalent to building two new buildings on the original basis."

For exterior walls, the price is quite high.”

"Money is not an issue." Guan Lin smiled.

Mi Fang still didn't know that Guan Lin had found a cornucopia, and now he was poor and only had money left.

In fact, Guan Lin was thinking about it.

——"When Hao Zhao was guarding Chencang, could it be that Chencang City had this kind of structure? There were two walls inside and outside... That's a bit interesting!"

——"Is this the reason why a thousand men held Zhuge Liang's 30,000 soldiers at bay for more than 20 days?"

Just as Guan Lin guessed...

Indeed, the Chencang City built by Hao Zhao twelve years later was brilliant on the inside and had two outer walls. This was equivalent to directly defeating Zhuge Liang's greatest threat to the city - Jinglan Offensive.

In addition, a large amount of ordnance and military equipment were stored between the inner and outer walls, which saved the soldiers time in moving the equipment.

It seems that a thousand people are more effective than ten thousand people.

The rush car was smashed by a ‘stone mill’ tied to a large rope;

The ladder was burned with arrows of fire;
