Mu Tianen didn't pay attention to the Xie family at all. She was very busy today, not busy studying but looking up information about Country K.

Now that she could not investigate David Lean for the time being, she would first investigate Country K.

Mu Tianen thought about whether she could find any clues from Country K's imperial family. She did not want to stop just like this and just waited.

Therefore, every day, apart from taking class, she held the portable computer and look for the information in her seat.

Qiu Ziyi did not know what she was busy with, but she was not curious.

Leng Yan came to pick up Mu Tianen. Seeing that she was exhausted, leaning on him and rubbing her wrist, he raised the soundproof board and asked, "What's wrong?"

"I looked for Country K's information for the whole day. I'm so tired." Mu Tianen rested her head on Leng Yan's chest and closed her eyes.

Leng Yan held Mu Tianen's right hand and rubbed it, "David Lean returned to Country K. Although I had people divert his attention, he is also very suspicious. He won't stop suspecting for a while, so we have to wait patiently."

Mu Tianen also understood it. However, she could not help but feel a little disappointed. She nuzzled Leng Yan's chest like a little kitten and acted cutely.

Leng Yan lowered his head and kissed her hair, "You don't have to investigate Country K. I've already done it. David Lean was a premature baby during a difficult labor. That's why his health is poor. When giving birth to him, his mother also bled a lot and couldn't be saved."

"His mother was from Country A. When going to Country K on vacation, she was fancied by the king at that time. It was well known that David Lean had been in poor health since he was a child, but one thing had been hidden."

Mu Tianen was curious. She opened her eyes, raised her head, and blinked her eyes, "What do you mean?"

Leng Yan also lowered his head and looked at her, "David Lean's doctors have all concluded that it will be difficult for him to live past forty years old."

Mu Tianen suddenly sat up. Fortunately, Leng Yan retreated quickly. Otherwise, their foreheads would have bumped.

"That's impossible. He is at least fifty years old now. My Master is already over fifty."

However, Mu Tianen's movements were still very big. If not for Leng Yan hugging her waist with both hands, her head would have reached the roof of the car. It would be very painful.

Leng Yan lowered his voice and comforted her, "Don't worry, I've already confirmed it. These conclusions were already vetoed when David Lean was 40 years old. However, I still found some evidence from his doctors back then."

He hacked the computers of all the doctors who had treated David Lean. At that time, he felt strange when seeing it. A doctor might have misdiagnosed, but all the doctors had the same opinion. They were all imperial doctors. That was very strange.

Perhaps it was not the doctor's diagnosis that was wrong, but that a change happened in Lean's body. He saw a doctor less frequently after he was forty.

Mu Tianen's delicate facial features were all wrinkled together, but her brain worked quickly, and an idea flashed in her mind, "I probably guessed why David Lean wanted to get close to my Master back then."

"There was a Taoist priest in Master's family who left behind a lot of mental cultivation methods, martial arts, cultivation, and even more medical skills. Mommy once said that my Master is Yuan Family's most outstanding and talented child. It's just that when young, she yearned for freedom and the outside world. She didn't care much about studying."

"Since she returned to Mount Qingyun, she has been more focused. She has taught us a lot over the years."

"My Master is very good at medicine. I have only learned a few of her medical skills, so I think what David Lean wants is some of Master family's medical skills or medicine."

Mu Tianen quickly sat down and lowered her head to take out a porcelain bottle from Eight Treasure Bag. She waved it at Leng Yan, "For example, like this."

Leng Yan also remembered that he had found out about Yuan Family's origin before. Not surprisingly, some ancient families existing today must have their foundation. Back then, Yuan Family opened a Chinese Medicine Hall, which was trusted by many officials and noble people.

"What is this?"

"The pills that Master refined. Although it can not save lives, it can help a lot when you encounter an expert and suffer serious internal injuries. The seven of us all have them. They were all given by Master when we went down the mountain."

Mu Tianen looked down at the small bottle, with her eyes full of longing for Master.

Leng Yan pulled Mu Tianen into his arms again, with his eyes filled with affection, "Alright, stop thinking about it. I'll find out."

Mu Tianen held the bottle tightly and slowly closed her eyes.

As soon as Mu Tianen returned home, she told her senior brothers and sisters the clues.

The next day, Mu Tianen lay on the table, bored. Qiu Ziyi came in and sat down, "Tianen, I just heard from the teacher that we have to learn K language from today on."

Mu Tianen was originally sleepy, but when hearing this, she immediately sat up, "K language, what's going on?"

K language was not commonly used, with few students studying it. So only clubs in the school taught it, with more than fifty people in the whole school.

Qiu Ziyi shook her head, "I don't know. I just happened to hear the teacher say that we will have it in the afternoon."

"Oh." Mu Tianen had already taken out her phone to ask Eldest Senior Brother about it. She didn't know if it was her imagination, but she felt that it was strange to have such a situation at this time.

Jin Yi was also not clear about this situation. He had just asked the dean. The dean said that they were having exchange programs with Country K's university recently. It was about time for them to start studying.

Jin Yi also felt that it was a little strange, but after thinking about it, he had no clue and planned to wait and see.

Mu Tianen received the message and continued to lie on the table.

"Tianen, what's wrong?" Qiu Ziyi asked.

"I'm fine. I'm tired," Mu Tianen said weakly.

Just as Qiu Ziyi was about to ask, Mu Tianen added, "I'm tired inside."

Qiu Ziyi suddenly did not say anything. She put away her curiosity and studied seriously.

In the afternoon, the first class was also the first class in the K language. Everyone was inevitably curious and excited, looking forward to what kind of teacher would come.

Very soon, the secret was revealed. A woman came in with red high heels, a black dress, and a cowboy jacket, dressing fashionably.

Long black hair draped over her shoulders, with charming and sexy facial features, fair skin, and light make-up. with a smile on her face, she looked very enthusiastic.

"Hello everyone, my name is Liu Yiran."

Liu Yiran put down the book, wrote down her name on the blackboard, and then looked at all the students below, "Alright, let's start the class."

Mu Tianen was originally not interested, but she was bored and listened a lot.

After listening to the lesson, many people were also interested. Mainly because the teacher was charming, beautiful, and spoke very vividly.

Liu Yiran left after class, and many students followed, especially the male ones.

Qiu Ziyi asked, "Tianen, what do you think?"

Mu Tianen looked at the door and said thoughtfully, "It's pretty good. The teacher taught very well."

However, she just felt that Teacher Liu paid too much attention to her. Every class lasted an hour. She looked at her many times. It wasn't a casual glance, but a conscious gaze.

Although she had control over herself, her subconscious actions could not fool people.

However, Mu Tianen could not figure out the reason.

After school in the afternoon, Leng Yan had no time, so Mu Tianheng came.

Qiu Ziyi ran away with her bag after class, rushing to work.

Mu Tianen slowly walked out and saw her brother waiting from afar. She smiled and went forward, "Brother."

"Tianheng."

A pleasant voice followed.

Mu Tianen just heard this voice not long ago. She looked to her left and saw that it was Liu Yiran.

Liu Yiran also noticed Mu Tianen's gaze, "Little Mu."

Mu Tianheng also wanted to see her outside, but she did not show it on her face, "Why are you here?"

Liu Yiran approached with a smile, "I'm here as a teacher and teach K language. Long time no see."

"Long time no see. We'll be leaving first." Mu Tianheng turned his gaze to his sister, "Let's go."

"Okay, let's talk next time." Liu Yiran was used to Mu Tianheng's alienation.

She said to Mu Tianen, "See you tomorrow, Little Mu."

"Goodbye, Teacher Liu."

After getting in the car, Mu Tianen asked immediately, "Brother, do you know Teacher Liu?"

"Yes, she and I are college classmates. She also graduated from Haili, but we haven't seen each other since graduation."

Mu Tianen frowned. Was it because of her brother that she looked at her?

Mu Tianheng asked, "What's wrong?"

"She taught us." Mu Tianen did not voice her doubts, "She's very enthusiastic. It's only been one lesson, and everyone likes her very much."

"By the way, how are you and my second martial sister?"

"Not bad, not bad."

After three days of K language classes, Mu Tianen felt quite good.

After class, Liu Yiran didn't leave right away as she used to. Instead, she walked toward Mu Tianen, "Little Mu, I want to ask you something. Please help me tell your brother that we will have a class gathering this Saturday. Ask him if he will come."

"OK."

Liu Yiran smiled and nodded. After walking two steps, she turned back and asked, "Little Mu, what do you think of my class?"

Mu Tianen thought, "Very good. But I don't understand something in grammar."

Liu Yiran said, turning around to face Mu Tianen, "You can ask me any time."

"I will. Thank you, teacher."

Only then did Liu Yiran leave.

Mu Tianen looked at her back. In the past three days, she had been very kind and friendly to her, but she could not feel her sincerity.

Qiu Ziyi followed Mu Tianen's gaze, "What's wrong?"

Mu Tianen said as she looked away, "Nothing."

When Mu Tianen returned home and told Mu Tianheng, he replied that he knew.

Mu Tianen was stunned, "Then, brother, are you going or not?"

Mu Tianheng raised his hand and rubbed his sister's head, "Alright, gossip girl. I'll contact them. Go back and wash up."

Mu Tianen pouted, puffed up her cheeks, and left obediently.

Mu Tianheng took out his phone and turned on the call. A lot of messages had already asked him to go to the party. He was considering not because he was busy, but how to tell Feng Lan that he wanted to take her with him.

A moment later, Mu Tianheng still dialed Feng Lan's number. It rang for a long time before being gotten through. A slightly tired voice sounded, "Ah Heng."

Mu Tianheng frowned, "Ah Lan, where are you now?"

Feng Lan asked with a smile, "On my way home. Why did you call me?"
