Nangong Jing took out the half-written letter, seeming to be worried and a little confused.

"Tell me, what did you find out?"

Ah Qi drank two cups of tea before he slowly spoke.

Officials in the Nanzhao Kingdom all had files from the time they entered office. When they took the imperial examinations, when they became officials, when they were promoted, and whether they had any faults were all recorded.

When Ah Qi looked up this information, he came across Sheng Yu's information about the imperial examination.

He was from Yue'er Town, which was under Fenglingdu of Nanzhao State. His parents drowned when he was ten years old. Sheng Yu was taken care of by his neighbors and had food to eat and books to read.

After passing the imperial examination, he held a low official position and received little salary in the following years, but he sent all his monthly salary back to Yue'er Town to those who had helped him in the past.

The records show that Sheng Yu was a good official who was grateful and diligent in serving the people.

He is a very tactful person and is good at handling things, so he was able to serve as the city lord. However, in the transfer of officials in the court over the years, he never went to the capital to take up the post.

Although it seemed that there was no problem, Sheng Yu did not seem to be in a hurry at all.

Officials in the government are all very clear that after three years of being sent out to serve in other places, they will be transferred to Beijing to serve. This is a great opportunity for officials to be promoted.

Every year, he would run around to build good relationships with colleagues and superiors, taking this opportunity to get promoted to a position in Beijing and pave the way for the future.

But Sheng Yu never made any arrangements, as if everything was done as he pleased.

This is really unbelievable.

After checking the files, Ah Qi went to Fenglingdu Yueer Town to look for them.

After checking, it was discovered that all the people who had been rewarded by Sheng Yu had either died or left, and not a single family was left.

Some died of illness, some died from injuries, and some left this place with their families for business and never returned.

After some inquiries, it turned out that no one knew Sheng Yu.

"Your Majesty, when I was trying to find out about Sheng Yu, I discovered that Yue'er Town has always had officials transferred from other places by the imperial court. The young master said that there are about 100 to 200 candidates each year, but not a single one of them passed the exam."

"You mean, apart from Sheng Yu, no other students have passed the exam in recent years?"

Nangong Jing immediately grasped the key point of Ah Qi's words.

Ah Qi nodded and said, "Yes, since Sheng Yu, no student in Yue'er Town has been able to pass the exam. There is a rumor circulating among the locals that Yue'er Town is not blessed by the gods, so if you can't pass the exam, you can only go somewhere else if you want to pass it!"

Nangong Jing frowned. He didn't know whether this rumor was true or not, but the fact that no students passed the exam was very telling.

Hasn’t the imperial court discovered this over the years?

It's so weird.

Ah Qi paused, and then said, "I have discovered another thing. When Nanzhao and Yeyou were on good terms a few years ago, Yue'er Town was extremely lively. It was once a border trading market, and people from Yeyou and Nanzhao could be seen exchanging goods and doing business everywhere!"

"It was when the late emperor was still alive!"

"That's right. The late emperor was determined to open up trade between the two countries and allow the people to develop. I heard from the locals that Yue'er Town was peaceful at that time, and the relationship between the people of the two countries was very good. There were even men and women who expressed their true feelings to each other and finally got married!"

Hearing this, Nangong Jing was shocked and said, "Become a couple? The people of Nanzhao and Yeyou become a couple? Give birth to a child..."

Ah Qi was a little confused again. Isn't it normal to get married and have children?

"Yes! I heard that many people got married back then! They lived happily. If it weren't for..."

If Nanzhao and Yeyou had not suddenly opened their doors, the trade would not have been closed.

Nangong Jing pointed at the letter on the table and said, "Open it and take a look!"

Ah Qi looked at the Nangong mirror, not knowing what it meant, so he opened it and said in surprise, "This, this is the writing of the Night Traveling Country!"

Nangong Jing nodded and said, "Have you seen it when you were in Yue'er Town?"

Ah Qi shook his head and said, "No, it's completely deserted now, as if it's been abandoned!"

"This is the letter the king saw written in the city lord's study when he visited the city lord's mansion at night a few days ago!"

"Sheng Yu? He, he is a night walker?"

"I'm not sure yet, but he definitely has some connection with the Night Travel Nation!"

This is true, but I don't know how they communicated the message simultaneously.

"Did you see the notice at the city gate when you came back?"

"I saw it. The city lord's house was robbed and valuables were lost. Now entering and leaving the city is more strictly controlled than before."

Ah Qi thought Nangong Jing was going out, so he asked this.

"The city lord lost this letter. It's his secret, so he's naturally worried!"

Ah Qi didn't understand what happened in between, but he believed Nangong Jing's words.

"Your Majesty, are we leaving the city now? Or..."

Nangong Jing raised a playful smile and said, "Wait a little longer, there are still some mysteries to be solved!"

The other half of the letter was taken away by another person, and Nangong Jing now really wanted to know where the letter was.

In the military camp outside Langzhou City.

After Li Feng left early that morning, he went straight back to the military camp, but was caught red-handed by Li Mao.

Military orders are as heavy as mountains. Anyone who leaves the barracks without permission will be beaten with a stick.

Li Feng was willing to bear it, but he whispered in Li Mao's ear: "Brother, I went to the City Lord's Mansion last night and discovered a big secret!"

Li Mao looked at Li Feng's mischievous face and refused to believe what he said. He shouted, "Someone, take him away!"

"Brother, brother, General, General, what I said is true, and I have evidence!"

As soon as Li Mao raised his hand, the person holding Li Feng immediately let go.

"You'd better come up with some decent evidence, otherwise I won't let you off easily!"

Li Feng obediently took out the half letter and said, "This is the evidence!"

Li Mao opened the envelope with doubt, because Li Feng and Nangong Jing each grabbed half of the letter.

He got the lower half, so there were not many words on it, but it was also possible to tell that it was not the writing of the Nanzhao Kingdom.

Li Mao just took a look and found nothing unusual except the strange text.

"Is this the evidence?"

Li Feng said with a serious face: "Yes, brother, someone is trying to snatch this letter from me, which shows how important it is!"

Li Mao looked at Li Feng suspiciously and said, "It's just some random words, don't try to trick me here!"

"Brother, you... this is not just a few random strokes, this is the writing of the Night Travel Country!"

Li Mao's originally relaxed face suddenly turned slightly pale and shocked.

"You, what did you say?"

Li Mao was a rough man. He had never liked the things of literati since childhood. He was forced to read some books and then practice martial arts.
