"I'll check for myself?" Yuwen Fei's face congealed, and with a wave of the fan in his hand, he pushed away the imperial edict in front of him.

Just as the two of them were rejecting, the imperial edict fell from Huai Jin's hands and was about to fall onto the ground.

Seeing the decree, Wei Chengwu's heart jumped out from his chest. Seeing that the decree was about to fall, he immediately rushed forward to receive it.

My mother, this is an imperial decree! These two people were too careless.

Wei Chengwu carefully examined the decree, and seeing that there were no major issues, he patted his chest in relief.

"He answered!"

"She answers!"

The two voices sounded out at the same time. Their postures were surprisingly synchronized as well. Both of them had their arms crossed as they looked at each other, clearly having no intention of receiving the orders.

Seeing the two of them like this, Wei Chengwu was troubled for a moment.

Yuwen Fei chuckled, "Royal father has given us two names to investigate this case, what do you mean by asking me to do it myself?"

Huai Jin scoffed, "Seventh Prince still knows that it's the two of us investigating the case."

The word "two people" was particularly harsh.

Yuwen Fei was startled, and helplessly shook his head.

The reason Huai Jin acted this way was clearly because she was angered to the point that she didn't even want to tell her anything. Yuwen Fei squinted his eyes, looking carefully at Huai Jin's angry look, he felt it was funny.

"I'll tell you later."

Yuwen Fei's lips slightly opened as he whispered into Huai Jin's ear.

The man's low and hoarse voice lightly sounded by his ear. Huai Jin was stunned for a moment, and felt that his ear was extremely hot. She took a step back and widened the distance between her and Yuwen Fei.

When Yuwen Fei saw her slightly red ears, the light in his eyes flickered. He turned around and asked while smiling: "Is Princess Anping willing to investigate the case with me now?"

Huai Jin rolled her eyes as she took the imperial edict from Wei Chengwu's hands and stepped onto the carriage.

"What are you doing in the carriage?" Yuwen Fei rubbed between his brows and laughed.

"To the Grand Princess Mansion."

Who told you to go to the Grand Princess Mansion to investigate?

There was a hint of mockery in his frivolous tone.

The curtain on the window was suddenly lifted. Huai Jin, who was sitting in the car, glared at Yuwen Fei fiercely through the window. With an unfathomable smile on her face, she asked word by word, "Then Seventh Prince, where should we go?"

"Go to the east gate!"

The east gate of the capital was the busiest of the four, for no other reason than that it was the only entrance and exit for foreign merchants from the capital into and out of the capital.

In order to facilitate the management of foreign merchants, the capital had established a rule that all foreign merchants must enter and leave through the east gate.

The east gate was a distance away from Huai Jin's Princess Mansion, so in the end, Huai Jin got off the carriage and chose to ride with Yuwen Fei towards the east gate.

Yuwen Fei's horse was the silver white horse that he had seen before in the hunting grounds, and Huai Jin's was the powerful horse that Yuwen Fei had tamed.

The Fierce Demon Horse was brought out, and when it saw Yuwen Fei, it intimately rubbed itself against his body, causing the silver white horse to snort loudly. If not for Yuwen Fei's constant consoling, it would have already trampled on the Fierce Demon Horse.

Yuwen Fei took the reins from Yun Jing's hands and passed the strong horse's reins to Huai Jin, while he himself pulled his horse over.

Her silvery-white figure agilely and elegantly walked around the Fierce Horse a few times, as if she was showing off. Finally, she proudly stopped beside Yuwen Fei.

Yuwen Fei smoothed its fur and introduced it to Huai Jin: "This horse is called — —"

After saying its name, Yuwen Fei paused, a glint flashed in his eyes, and he changed his tone: "It's called Baiyun."

"White Cloud?!" Huai Jin didn't dare believe her ears. How could Yuwen Fei give his mount such a vulgar name?

As for the Silver Shuttle, which had just been renamed to a white cloud today, it was also restlessly stamping its hooves as it protested to Yuwen Fei.

Yuwen Fei did not care about Baiyun's protest. He raised his eyebrows and pointed to Huai Jin's horse, then continued, "This horse is yours from now on, you can give it a name."

Giving the horse a name was not something that Huai Jin was good at. She only found a horse of a similar color to the one on the map and casually said: "Then, let's call it Chiji."

Although the Chiji didn't really like Huai Jin, it liked him a lot when she had a name.

He proudly displayed a circle to Bai Yunlai and dashed forward on his horse's hooves.

Xiao Bai was still protesting about his new name. In the face of the Chiji's provocation, he didn't have any fighting spirit.

Yuwen Fei comforted Bai Yu for a while before he finally got interested and chased after her.

The two horses were like a battle spirit, chasing each other and shaking off their hooves.

Huai Jin held on tightly to the reins to prevent herself from falling down.

Because the Chiji was being held onto tightly by the reins, it could not even let go of its feet, and could not help but stumble as it ran.

Yuwen Fei's voice came from behind.

"Push down, don't grip the reins too tightly!"

Yuwen Fei's voice was getting closer.

The Chiji that was released suddenly increased its speed after getting the space.

Huai Jin lost her balance and fell backwards. She knew that something was wrong and hurriedly changed her posture, preparing to dismount in the nick of time.

However, before she could even turn around, she felt a hand behind her back, supporting her and bringing her back to the horse.

Huai Jin tilted his head, the sweet smell of incense, and it entered her nose along with the wind.

Yuwen Fei smiled at her and then called her over.

Huai Jin looked at the figure of her back in front of him, urging the Chiji to catch up.

When the two of them arrived at the east gate, they saw the bustling scene there.

Each of the clerks held a book in their hands as they carefully checked the merchants' allotments and goods.

After checking, glance at the booklet to see if it is a tick, a fork, or a circle mark.

He indicated that the goods were not a problem and that there was a huge problem. Usually, the caravans that were forked would not be allowed to enter the city or the city, and would directly send them to the Stacha.

Those who were in the trap expressed their doubts, but they still needed to be checked by the Chamber of Commerce that managed these foreign businesses.

Everything at the east gate was progressing in an orderly manner.

Yuwen Fei reined in his horse, and when Huai Jin arrived, the two of them headed towards the group of officials.

"What are we doing here?"

Yuwen Fei pointed to the people coming and going from the east gate, and asked: "Look at those people, is there anything different about them?"

Huai Jin took a close look in the direction of the city gates, and saw many carts pulling goods coming and going. Although she didn't know that the east gate was the only passage for foreign merchants, she could tell that the people here were probably merchants.

"From the looks of it, they probably came to the capital to do business."

Yuwen Fei nodded his head, "That's right, these are all foreign merchants, and the east gate is the only gate that allows foreign merchants to enter."

"What does that have to do with the Qishan white jade case?" Huai Jin did not understand.

The corner of Yuwen Fei's mouth curled up, and he looked up at her. "When was still alive, not long ago at the Elementary palace feast, he had once left this place."

Huai Jin did not understand the system of city gates, and only furrowed her brows as she looked at Yuwen Fei.

Yuwen Fei smiled and shook his head, "Normally, the powerful nobles of the capital would not come in and out of the east gate. Those rich and powerful people despise these people the most. "

Huai Jin suddenly realized.

Yuwen Fei took out the jade pendant that represented his identity, and threw it into the small official's hands.

The young official was having a headache from seeing such a dense list of words. At this moment, he couldn't help but feel angry when he saw someone disturbing him. He was about to open his mouth to curse, when suddenly, the eye-catching words' Yuwen 'on the jade pendant caught his eye.

Although the clerks who were selected to work here could not write much, they could read a few words. When they saw the words' Yuwen ', they immediately shut their mouths, raised their heads and revealed a smile, then smiled apologetically: "Sir, do you have any questions?"

Yuwen Fei chuckled and kept the jade pendant, "Call your leader over, and bring me the books from before the next day."

The official did not dare to be negligent and hurriedly put down the book in his hand. He quickly ran over and called his captain in front of the two of them.

The captain had more experience than the official, he recognized Yuwen Fei and Huai Jin with a glance, and immediately bowed: "This official pays his respects to Seventh Prince and Princess Anping."

Yuwen Fei said indifferently, and told him to get up.

After the captain got up, he led the two to a small room on duty behind him and asked with a smile, "I wonder what the Seventh Prince wants this booklet for?"

Yuwen Fei shot him a glance, opened the fan in his hand, and gently shook it: "By order of the emperor, come investigate."

As he spoke, he took out the imperial edict from his robes and placed it on a nearby table.

When the captain saw that bright yellow imperial edict, how could he dare to say anything else? He hastily took out the book and handed it to the two of them.

Yuwen Fei opened the book and read page after page. Sure enough, on the records two days ago, he saw the name of Grand Princess Ping Yang.

"Who was on duty that day? "Call him over," Yuwen Fei said as he closed the book.

The captain lowered his head and thought for a moment. Then, he turned around and called out.

Soon, a Old Magistrate came in.

"Two days before the next Festival, on the thirteenth day of the tenth month, was it you who deserved to work?"

Yuwen Fei sat in front of the table and asked.

"Exactly."

Old Magistrate bent down slightly and answered respectfully.

"Tell me about what happened that day in detail."

There were no rich people entering or leaving the east gate, so when Ping Yang suddenly came, he left a deep impression on the Old Magistrate, although she was surprised at why the two of them asked him about it, she still patiently told them everything that had happened that day.
