Cao Heng led his team from Yanmen Pass to Luoyang.

After walking for a long time, they finally arrived at Luoyang City.

Luoyang City has a magnificent temperament, and the city walls alone are much taller than Shouchun.

When he arrived at the city gate, Cao Heng looked up at the top of the city.

On the top of the city, the Wei army's battle flag was flying in the wind.

Cao Shu had not yet proclaimed himself emperor, and the Wei Dynasty only had the battle flag at present, and there was no flag to be built to swear sovereignty on the top of the city.

"Sir, why don't you go into the city and just watch here?" Cao Zhang asked him.

"I have seen many cities after walking through so many places. I always thought that Shouchun's walls were the most magnificent. I didn't expect that compared with Luoyang, Shouchun would have become a small city." Cao Heng said with a smile: "If my father hadn't asked me to come here, I wouldn't have known that there was a big city like Luoyang in the world."

"Just when I saw Luoyang, the eldest son sighed like this." Cao Zhang replied with a smile: "Shouchun cannot be regarded as a small city, but when it comes to the city wall, Dayoucheng is more dignified than it."

"Why didn't my father strengthen the city defense of Shouchun City in the past?" Cao Heng said: "Now it seems that Shouchun has a lot less demeanor than these cities."

"Is there really less temperament?" Cao Zheng asked with a smile.

"Isn't it?" Cao Heng said: "Just talking about city defense, Shouchun is not as good as Luoyang and other places."

"It's not necessarily a bad thing to be better than the city defense." Cao Zhang replied: "Your father never thought about defending back then. For him, no matter how stable the defense was, he did not lead the soldiers to defeat the enemy. Since the enemy could not reach the doorstep, why did he build the city defense so firmly?"

Looking up at the towering Luoyang city wall, Cao Zhang said: "Luoyang is indeed a profound city, but what has it blocked for this former imperial capital over the years? The profound city walls not only blocked the enemy coming to invade, but also blocked the people in the city. Being in such a city, it is easy to have a thought that as long as I don't go out, the enemy can't come in. If they can't come in, we will not be in any danger."

Looking at Cao Zhang, Cao Heng suddenly smiled.

"What are the eldest son laughing?" Seeing him laughing, Cao Zhang asked in surprise.

"I don't laugh at anything." Cao Heng said: "It's rare to see Uncle San look so serious."

Cao Zhang smiled and shook his head: "I went to Yanmen Pass, and you are different from before. You talked to Uncle San a lot more casually."

"No." Cao Heng replied: "I was just thinking, if we follow the third uncle's words, wouldn't the Great Wei Dynasty not need a city in the future? We might as well demolish the Great Wall and demolish all the barriers. Without waiting for the foreign race to invade, we will fight out first so that they have no chance to invade."

"It's not impossible." Cao Zhang smiled and said, "The people of the Central Plains have always made a living by farming. They live in a fixed place and will not change their residence for many years. There are even old people who think that as long as their home is settled, they should not leave their hometown easily. However, the foreign races in the north are all nomadic people. They have no fixed place to live, and wherever the water and grass are plump, they will go. With the habits of the people of the Central Plains, if they can withstand the harassment of the foreign races in the north without the Great Wall barrier, have the eldest son thought about it carefully?"

"Of course I thought about it." Cao Heng replied: "I just said this, but I was just joking with Uncle San. Demolition of the Great Wall is a good thing for the northern alien races, because they can drive straight into the Central Plains. Although we Central Plains people have a strong army, it is impossible for us to guard against each other everywhere, and it is even more impossible for us to send large troops to attack the alien races at all times. The Great Wall is still necessary for the Central Plains people."

Looking up at the head of Luoyang, Cao Heng continued: "It is still necessary to have a tall city wall like Luoyang. What the city wall can play is of course a defensive role. Will it lose the belief in fighting because of the existence of the city wall? The key is the hearts of the people, not how strong the city defense we have."

"The eldest son is right. The key is the hearts of the people, not the strong city defense we have." Cao Zhang agreed immediately.

"Enter the city." He talked to Cao Zhang at the city gate, and Cao Heng called everyone into the city.

After entering Luoyang City, he looked back and asked Cao Zhang again: "Uncle Third, when will I be able to follow me?"

"Don't worry about him." Cao Zhang replied, "As soon as he entered the Luoyang territory, he couldn't help but walk around. People like him are restless and uneasy at any time. When he replied, Luoyang, he didn't have to pay attention to his existence. He could do whatever he wanted, but your father wouldn't summon him anyway."

"I always feel that there seems to be something that cannot be resolved between my fourth uncle and my father." Cao Heng asked: "Does the third uncle know what happened between him and his father?"

Of course, Cao Zhang knew why Cao Zhi became like this now.

When Cao Shu killed Cao Pi, Cao Zhi tried to plead with love, but he said he did not give him a chance to plead with love.

A seven-step poem, before he could finish it, Cao Shu had already read out the next two sentences.

Cao Zhi pleaded for Cao Pi but was rejected by Cao Shu. From then on, he knew that Cao Shu was fundamentally thinking about killing Cao Pi.

He had never considered letting Cao Pi survive.

So I gave the opportunity to become a poem in seven steps, which was nothing more than a determination that Cao Pi did not have the ability, so I made such a request.

He didn't expect that Cao Zhi, who was almost killed by Cao Pi, would stand up and speak at any time.

It is indeed difficult for Cao Pi to make a poem seven steps.

But it is not a difficult task for Cao Zhi, who has always been famous for his talent.

It was precisely because Cao Zhi's plea was rejected by Cao Shu that from that time on, he believed that Cao Shu was also a person who had no human feelings like Cao Pi.

Even the biological brothers can be killed, but Cao Zhi couldn't understand why such a person is always the one who finally achieves great achievements in the world.

The Great Wei became stronger and stronger, and Cao Shuo's prestige in the Great Wei became higher and higher.

In such an environment, Cao Zhi chose not to care about the world anymore, and would hang out with a group of idle people in the market every day.

At first, Cao Shu looked for him a few times, but later, Cao Shu was too lazy to find him. Gradually, Cao Zhi became an optional person in the Great Wei Dynasty. Almost few people could remember Cao Zijian, who wrote the Tongquetai Fu back then.

Of course, Cao Zhang knew what happened between Cao Shu and Cao Zhi.

But in front of Cai Heng, he couldn't explain it too clearly.

After all, there are some things that Cao Heng knows the less, the better.

Without answering Cao Heng's question, Cao Zhang just grinned at him: "Young Master, don't think so much. Many things except myself cannot figure out what happened."

I heard from Cao Zhang's words that he didn't want to explain, Cao Heng stopped asking questions and went back to Luoyang Palace with him.

When they came to the palace, they were greeted by them not any Deng Zhan or Zhu Ao, but a guard commander.

The guards accompanied him to the palace and Cao Zhang asked, "Is the King of Wei here?"

"It's a coincidence that the King of Wei is here every day, but he is not here today." The guard commander said: "The King of Wei is working hard every day. He invited Mrs. Zhen to Luoshui early in the morning, saying it was a boat trip. Maybe he could come back today, but maybe he wouldn't come back."

I thought I would see Cao Shu when I came to Luoyang, but Cao Heng didn't expect that he would actually make an appointment with Zhen Mi to raft on the Luoshui River.

Cao Heng was somewhat disappointed when he failed to see Cao Shu immediately.

But he didn't ask Cao Shu when he would come back, but instead changed the topic and asked the guard commander: "Did the other wives go together except Mrs. Zhen?"

The guard commander replied: "Reply to the eldest son's words, except Mrs. Zhen, no other wife follows him."

"Since my father is not sure when he will come back, I will go to see my grandmother and mother first." Cao Heng thought to Cao Zhang and asked, "Does the third uncle want to join me?"

"I'm going to see my stepmother and sister-in-law, of course I'm going to go." Cao Zhang responded immediately.

The two walked towards the inner palace of the palace together.

***************************************

When Ding Yao heard that Cao Heng had come back, she had been looking at him outside the courtyard door.

When Cao Shu returned from outside, she was the same.

But now he treats Cao Heng more carefully.

When Cao Shu returned, Ding Yao was mostly in the room and would not welcome him outside, but when Cao Heng came back, she met outside the courtyard and waited eagerly.

Grandmothers often treat their grandson more than mothers.

The year when Cao Shu abandoned Yecheng, Cao Heng was still a ignorant child.

When Ding Yao arrived in Shouchun, in order to make her life less boring, Yuan Fang sent Cao Heng to her residence and accompanied her grandmother all day long.

Originally, he was his grandson, and he grew up by his side every day, so Ding Yao's feelings for Cao Heng are of course getting deeper and deeper.

Although she was not so doting that no matter what Cao Heng said, she would definitely be satisfied unconditionally, but Ding Yao's love for Cao Heng was almost beyond the love for Cao Shu.

Seeing Cao Heng from afar, Ding Yao ordered the maid beside her: "Hurry, come with me quickly, my grandson is back."

The maid accompanied Ding Yao out of the courtyard and came over to Cao Heng and Cao Zhang.

Ding Yao ran over, and Cao Heng also accelerated his pace.

When he arrived, before he could salute, Ding Yao had already stepped forward and held his hands, his eyes were only on his face, and he looked back and forth.

"Grandma..." In front of an outsider, Cao Heng called Ding Yao to be his grandmother, but in private, his name for Ding Yao was much more casual.

"I've lost weight when I'm black and thin, and I've grown taller." With crystal tears in my eyes, Ding Yao said: "Just like your father back then, I'll be much darker and thinner when I go out, and I'll be much taller..."

"I am growing taller every day by my grandma." Cao Heng said with a smile: "I just came to Luoyang and just went to ask for my father, but he was not there. I asked the guards, but I didn't know when my father would come back. I didn't wait there, come and report my grandma to my safety first."

"It is necessary to report peace to grandma first." Ding Yao said with a smile: "You have grown up, and in a short time you will be like your father, and you will never see anyone all day long. Grandma's heart..."

Speaking of this, the tears in Ding Yao's eyes became even brighter.

"Grandma, don't be sad, grandson is not back." Cao Heng quickly comforted: "In the future, as long as I am in Luoyang, I will stay by my grandma's side and never leave for a moment."

"You are much more sensible than your father." Ding Yao smiled, holding his hand and said, "I heard that when you came back, grandma had someone make your favorite pastry. You are really the same as your father, and there is no difference between what you like to eat."

Ding Yao took Cao Hengjiang to her residence, and she also greeted Cao Zhang who was following behind and said, "It's also hard for Ziwen to accompany Henger this time, so she also came over to have some pastries."

"I won't bother my legitimate mother." Cao Zhang replied: "I came back from Yanmen Pass. Although I didn't see my brother, I still had to report to my sister-in-law. The eldest son stayed with my legitimate mother, and someone had to say something to her on his behalf."

"That's right." Ding Yao nodded: "Then you go."

Cao Zhang responded, bowed and turned away before turning around and leaving.

Ding Yao took Cao Heng back to her residence.

Cao Zhangze came to Yuan Fang's residence.

I had heard that Cao Heng returned to Luoyang, and Yuan Fang also knew that he must have gone to see Cao Shu first, then go to Ding Yao's place, and finally come to his place, so he was not in a hurry to make a reception.

Cao Zhang came, and Yuan Fang ordered the maid to invite him into the room.

Standing in front of Yuan Fang, Cao Zhang reported everything that happened at Yanmen Pass.

After hearing this, Yuan Fang said, "Heng'er is getting more and more arrogance now. Fortunately, you and Zijian are with him. If he only brings 5,000 permanent troops to pursue the Jie people, he will suffer from the pain when he is outside the pass."

"The eldest son is very skilled in martial arts and courageous, and is not inferior to the elder brother back then." Cao Zhang replied: "I think even if he leads the army outside Yanmen Pass, success or failure is still difficult to say."
