The theory that the earth is round is so shocking that Li Er has been doubting the authenticity of this news, let alone the two young princes.

When Xu Yang told Qingque and Gao Ming that the ball drawn on the blackboard was the world they lived in, these two princes trembled and couldn't believe it, and when they thought that the person who lived under the ball would fall into the dark void, they would be chilled, and they couldn't listen to Xu Yang's theory of gravity at all.

Seeing the two princes who fled from the study like ghosts, Xu Yang scratched his head, the theory that the earth is round is really difficult to understand? So much so that you will run away in fear?

However, the two princes escaped, and they didn't need to take their own classes, Xu Yang was also happy to be idle, wandering around the imperial city alone, it was good to think about it, but the two little eunuchs who were always followed by Xiao Fugui and Xiao Shunzi were a little awkward.

Out of the East China Sea Gate, Xu Yang didn't know where he had wandered, but just went around admiring the magnificent palace covering thousands of hectares.

After walking around for a long time, Xu Yang was also a little tired, so he planned to let the two little eunuchs take him back, but as soon as he looked up, he saw a tall city gate in the distance, which was Chengtian Gate, which was also the palace gate of the imperial city.

Xu Yang looked at the sun, it was only one or two o'clock in the afternoon, forget it, let's go to the East and West Market today, and then walked towards Chengtianmen, checked the fish talisman, and put the official seal, and the soldiers of Chengtianmen let Xu Yang out.

As soon as I came out of the city gate, I saw a team of armored guards taking over the shift, first checking the tiger talisman, then registering, and finally handing over today's entry and exit records, and this group of armored sergeants left work.

Most of the people in the team are the sergeants who defend the palace, so many of them are military garrisons who enter the palace, and some are the children of the nobles to increase their resumes, and they go home directly after work, but there are not many people, just a few people, and their homes are not far from the imperial city.

A few of them passed by Xu Yang, but when the last soldier in a green robe and armor passed by Xu Yang, the soldier suddenly snorted.

"Is that you?"

Xu Yang was very curious, who still recognized him? Look at the man's face.

I saw that it was an angular face, thick eyebrows and big eyes, a scruffy beard, it didn't look big, eighteen or nineteen years old, and the armor made him look a little old, although Xu Yang felt that this person looked very familiar, but he couldn't remember where he had seen him after searching his mind.

"Dare to ask Brother Tai, when have we met?" Xu Yang was very curious about the people who knew him, and asked with a fist.

As soon as the man saw Xu Yang saluting, he also made a gesture and said: "Lang Jun, don't be weird, we also met in Pingshui, do you remember when you entered the palace a few days ago?" In front of Chengtian Gate, Lang Jun brought a huge box at that time, and I didn't let my brother pass you. ”

Hearing this, Xu Yang suddenly realized and said, "It turned out to be you." ”

The man also smiled rudely, "It's down." ”

Xu Yang asked, "I don't know my brother's name?" ”

The man smiled: "Silence at the next stage, the word Huai Mo." I don't know what about you, brother? ”

Xu Yang didn't know that Cheng Chumo was the son of the famous Cheng Zhijie, so he just smiled heartily: "In Xu Yang, the word is free." ”

Cheng Chumo listened to Xu Yang's introduction and was very excited: "The word is free? Xu Gong is really a carefree person, the last time he gave a golden bean to Chengtianmen has been divided by my subordinates to buy wine, Brother Xiaoyao is generous, presumably it is also a certain noble family in Chang'an, right? ”

Xu Yang smiled dumbly and said: "The nobles of Chang'an don't dare to count, but they were appreciated by His Majesty some time ago and were named the founding county marquis, and now they have a fief in Zhongnan Mountain. ”

Cheng Chumo heard this, looked at Xu Yang again from head to toe, and asked in disbelief: "You are the disciple of the Ghost Valley from the overseas Immortal Mountain?" ”

Xu Yang was a little embarrassed, why did the ancient people gossip so much, did those who came from overseas have to come from Xianshan? Then he said: "It's just overseas, Xianshan is not counted, and it is indeed a disciple of Guigu below." ”

People are like this, a lie has to be filled with thousands of lies, and the name of the disciple of the Ghost Valley now Xu Yang lied and felt that what he said was true.

When Cheng Chumo heard that he was really a disciple of Guigu, he immediately rubbed his hands excitedly, as if he had encountered a great good thing, "Disciple of Guigu!" I always thought it was an old fairy man with a gray beard! I didn't expect to be so young, how old is my brother? ”

"In the next twenty this year, there will be one."

When Cheng Chumo heard this, he immediately laughed and said: "Hahaha, Yu Chi Baolin, this husband has been thinking of himself as a big brother all day long because he is a few of us when he is one year old, and now there is an extra heir of Guigu, and he can finally suppress the name of his boss." ”

Cheng Chumo said this in a fog in the clouds.

"I wonder what Brother Huaimo is talking about?" Xu Yang planned to ask clearly, otherwise the rough man looked violent, and he would not accidentally sell himself.

Cheng Chumo didn't ink, and directly grabbed Xu Yang's hand and said: "Brother Xiaoyao, come with a certain person, let you see those nobles in Chang'an City, they are all their own brothers, they are of the same age, and they will have a good time in the future." With that, he took Xu Yang's hand and walked towards the outside of the palace.

Cheng Biting Jin was named Lu Guogong, his mansion is also not far from the imperial city, walked about half a pillar of incense to Cheng's mansion, Cheng's mansion is indeed unusually atmospheric, facing the street to open the door, two armored warriors at the door guarded, there is a row of halberds on both sides of the gate, it is even more majestic, after the mud fang door into the Cheng's gate, two hundred-year-old sandalwood, painted with red paint, the door wall is painted snow-white, at a glance it is not beyond the reach of the prince.

followed Cheng Chumo into the Cheng family compound, the housekeeper was very respectful to Cheng Chumo, and seemed to be a little afraid of Cheng Chumo, Xu Yang followed Cheng Chumo to the back hall.

"Dare to ask Brother Whammer? Where are we going to see these nobles? Xu Yang walked a long way, felt tired feet, and just wanted to sit and rest.

"Of course, I went to their mansion to pay respects, you wait in this hall first, and I will send people to urge a few of them to come to the party." Cheng Chumo was very happy.

"Oh, good." Xu Yang was also very happy when he heard that he didn't have to go around anymore.

The nobles of Chang'an City have always been idle, many of the sons of the family in order to increase their resumes are to go to the palace as guards, known as Gong Wei Imperial City, as Li Er's throne sits more and more stable, those important ministers who fight the world with him have been shelved one by one, of course, their children and grandchildren are also unable to take power, so these noble sons have nothing to do all day long, and finally become a gentleman, Yu Chi Baolin, Li Chongyi, Li Dejian, these Wei Chi Jingde, Li Xiaogong, Li Jing's eldest sons often hold some private parties in Chang'an City, and of course, Cheng Yanjin's son Cheng Chumo is no exception.

It was they who Cheng was going to call this time.
