The whole family traveled through time and became doctors, raised children and farmed in ancient tim

"It's okay, Ah Xing." Cheng Fei raised his head slightly, forced a smile and tried to make his tone sound more relaxed. "I'll send someone to send you a letter when I get back. If you want to come to the capital to play in the future, I will definitely come to pick you up."

"Thank you, cousin. I haven't been to Beijing yet. I heard that it's very lively and there are a lot of delicious food." Xie Wanxing tilted his head, his eyes sparkling.

Cheng Fei reached out and gently touched Xie Wanxing's head, just like countless times before, his movements were gentle and doting: "Of course, when the time comes, I will take you to see the prosperous streets of the capital, visit the lively temple fairs, and let you eat at all the major restaurants in the capital."

Xie Wanxing nodded: "I will definitely go there in the future."

Cheng Fei said: "Oh, by the way, I found a teacher for you. His name is Wu Ji, but he went out to collect herbs recently and hasn't come back yet. When he comes back, I asked him to come here to find you. I know you want to learn medicine, so let him teach you."

Xie Wanxing was stunned at first, then her eyes lit up with surprise. She excitedly grabbed Cheng Fei's arm: "Really? Cousin, you're so kind! Thank you!"

"You're welcome. As long as Ah Xing is happy." Cheng Fei looked at Xie Wanxing with eyes full of doting. It was the unreserved love of a brother for his sister. He gently patted Xie Wanxing's hand, feeling her joy.

After spending some time together, he had long regarded Xie Wanxing as his own sister. He still remembered that when he was a child studying with Zhao Liulang, he was always particularly envious of his mother for giving him a sister. He often pestered his mother to give him another sister as soon as he returned home.

Cheng Fei raised his head and glanced casually, but his expression suddenly changed. His eyes went straight to the direction of the back mountain, where he saw a wisp of yellow smoke rising in the breeze.

Cheng Fei's eyes narrowed and he frowned, feeling heavy in his heart. If there was nothing important, Wu Yong and the others would definitely not contact him on their own initiative.

"Axing, stay here by yourself for now. Your cousin has something to take care of." Cheng Fei tried his best to make his voice sound calmer, but he couldn't hide the hint of anxiety in it.

Xie Wanxing was originally immersed in the joy just now, and was stunned by Cheng Fei's sudden words. Looking at Cheng Fei's slightly serious expression, although he didn't understand why, he could sense that something seemed to be wrong.

"Okay." She naturally wouldn't ask more about Cheng Fei.

Cheng Fei hurried towards the back mountain like a gust of wind. The surrounding trees quickly retreated beside him, and the dead branches and leaves under his feet rustled.

He quickly arrived at the place where he often met Wu Yong and the others. Wu Yong was already waiting there. He greeted him with a serious expression, "Prince!"

Cheng Fei stepped forward quickly and asked anxiously, "Wu Yong, what happened?"

Wu Yong frowned, his lips trembling slightly as he said, "Prince, I'm afraid Yongzhou is going to be in chaos!"

Cheng Fei's heart sank suddenly.

"The Sixth Prince sent people to support Wu Xin in Yongzhou. We originally thought we could complete the mission successfully, but who could have predicted that the other side seemed to have made no secret of their intentions? After a fierce battle, we suffered heavy casualties, Prince." Wu Yong clenched his fists tightly, his knuckles turning white. "Wu Xin was seriously injured while covering everyone's evacuation. I sent people to take him back first, and also notified Wu Ji to return to the capital immediately. I just hope he can hold on."

Cheng Fei's face darkened as he listened to the news Wu Yong brought him. A cold glint shone in his eyes. He clenched his fists, his knuckles turning white. He suppressed his inner rage and said through gritted teeth, "Stop pretending? Are the Yongzhou officials planning a rebellion? Who else is there?"

Wu Yong took a deep breath and slowly uttered a few words: "Looks like the Huns."

Cheng Fei's body trembled violently upon hearing this, and the cold light in his eyes became even more fierce. He repeated these three words in a low voice, and his anger seemed to have been added with dry firewood, burning even more vigorously: "Huns?"

Wu Yongdao: "It seems so, but the subordinates are not completely sure yet."

Cheng Fei said, "Although the Xiongnu are warlike, Yongzhou is located inland, far away from the Xiongnu's range of activities. How could they come to Yongzhou?"

The Huns have been roaming across the vast grasslands in the north all year round, living a nomadic life. They should have nothing to do with the inland area of Yongzhou. But now, they seem to have appeared out of nowhere and stirred up the muddy water of Yongzhou. There must be an extremely complicated conspiracy behind this.

Wu Yongdao said, "We have already delivered the news to the prince. The Sixth Prince should have received the news as well. Prince, should we go back?"

"Let's not go back to Beijing yet." Cheng Fei frowned and said, "Let's go to Yongzhou."

"Prince! You can't go to Yongzhou!" Wu Yong suddenly raised his head, his eyes fixed on Cheng Fei, his eyes full of anxiety. "Yongzhou may be in chaos, and your injuries haven't fully healed yet, how can you go to Yongzhou? It was already our fault that we let you go into danger alone to protect the Sixth Prince. This time, we absolutely cannot let you fall into danger again."

Cheng Fei shook his head. "My injuries are gone now. They won't affect my movements. I have to go to Yongzhou to confirm whether these people are Xiongnu. If they are, I'm afraid something serious will happen. I have to find my father to discuss countermeasures."

Seeing Cheng Fei so determined, Wu Yong became more and more anxious. He knew their young master's temper too well and knew that once Cheng Fei made up his mind, no one could pull him back. But he really couldn't bear to watch Cheng Fei fall into danger again.

So, he plopped down on his knees before Cheng Fei and said earnestly, "Prince, please, just listen to me this time. If anything happens to you, how will we explain to the prince?"

Cheng Fei patted Wu Yong's shoulder gently. "My injury is really not a problem anymore, you don't have to worry. Besides, I won't act rashly. Go gather some people, and we'll disguise ourselves and go into Yongzhou. We'll just see what's going on and come back. We won't deal with those people head-on."

He knew very well that Wu Yong's worries were not unnecessary, but he was even more aware of the urgency of the situation in Yongzhou. If the situation was not clarified as soon as possible, the consequences would be disastrous.

"Go and get ready, time is running out, we have to find out the situation before it gets worse." Cheng Fei said as he helped Wu Yong up.

Wu Yong listened to Cheng Fei's words. Although he was still worried, he also understood that Cheng Fei had made up his mind and any more persuasion would be in vain.

"Yes, Prince, I will gather people right away and will do my best to ensure that this operation is foolproof." Wu Yong gritted his teeth, his tone revealing helplessness but determination as he responded to Cheng Fei's order.

Cheng Fei also returned to the Xie family. He was in a particularly heavy mood along the way. When he saw Xie Wanxing, he really couldn't smile this time. He thought he could wait for a while before leaving, but he didn't expect that he would leave immediately.
