Mu Tianheng was also curious and looked at his sister through the rearview mirror.

"Car."

"Car? What do you mean?" Mu Tianyu still did not understand.

Mu Tianheng also did not understand it.

"It's the material of the car. It is anti-missile, including the window glass and the tires," Mu Tianen thought seriously, "There is also the driver who is driving. His breathing is light. When he leaves the car and opens the door, there is almost no sound of footsteps. He is an expert."

But this protective measure is a bit too much.

Mu Tianen said in her heart.

Mu Tianyu and Mu Tianheng looked at each other. Their sister used her knowledge to see a different world. They could not understand these things.

However, they still had doubts.

"Tianen, then why isn't Uncle Yu a rich man?" Mu Tianheng asked.

Mu Tianen frowned and thought for a while, "He doesn't have such a temperament. Moreover, Father didn't tell him anything about business. If Uncle Yu was a rich man, he must have cooperated with Mu Clan or Aunt Anqi, Wen Clan. They have such a good relationship. It's impossible for them to not talk about it."

"What is Uncle Yu's temperament like?" Mu Tianyu asked with a smile.

"The unfathomable temperament of an expert."

It had to be said that Mu Tianen's eyes were sharp with good observation skills.

"Then, can you guess how important a character he is?" Mu Tianheng was interested and asked how much his sister could see.

Mu Tianen shook her head, "Auntie Zhou said she often travels around the world. That is diplomacy, but it doesn't matter. I know that they are all good."

Mu Tianheng and Mu Tianyu looked at each other and smiled. They knew Yu Yan and Zhou Yun were good to their sister.

"You guessed it right. Uncle Yu and Auntie Zhou just came back less than a week. They heard it was your birthday today, so they asked Mommy to have dinner with Aunt Anqi," Mu Tianheng said.

Mu Tianen nodded. Her phone vibrated as she took it out to look. It was from Leng Yan. He had something to do tomorrow and could not go to the Yu Family.

Mu Tianen replied she knew.

The Mu family had breakfast. Mu Tianheng and Mu Tianyu went to work. Mu Zongwen and Wen Jia took Mu Tianen out.

Mu Tianen soon noticed that the car had driven to a private place.

They were checked three times but hadn't reached their destination.

Wen Jia noticed her daughter's severe expression and thought she was worried. She raised her hand, placed the hair behind her ear, and said gently, "Sweetie, it's fine. This place is the safest. Your Uncle Yu's father is the most powerful person in this country. The place he lives in is naturally more secure."

"Oh."

Mu Tianen looked out and saw security guards and surveillance cameras everywhere.

After driving for another five minutes, the car finally stopped. In front of them was a three-story white house. Zhou Tian stood at the door and waited with a smile.

"You're here. It must be troublesome on the way, right?" Zhou Tian greeted them and asked.

"No trouble," Wen Jia replied, "That's normal."

Zhou Tian looked at Mu Tianen. Her expression was indifferent as she was not curious about her surroundings.

Zhou Geng had more admiration for Mu Tianen in her heart. Many people were curious about this place. She said to the three, "Let's go in and sit first. Ah Yan has to be busy for a while. My dad also wants to see Tianen."

Hearing this, Mu Zongwen and Wen Jia looked at each other. Although no expression on their faces, their eyes darkened. It was the honor of their younger daughter to meet the respectful, serious, and busy senior man.

They went in and sat down. Although Mu Tianen was not curious, the simple and elegant decoration stunned her for a moment.

As a place with the strictest security in Country A, it was only right to be more luxurious.

Zhou Tian asked someone to serve the tea and took the gift from her room. She said to Mu Tianen, "Tianen, I was in a hurry yesterday. This is the birthday present that your Uncle Yu and I gave you. Take a look."

Mu Tianen took the gift and thanked her obediently. Just as she was about to look down, her attention was attracted by the sound of light footsteps. She turned to look.

The other three were also puzzled and followed Mu Tianen's sight.

A woman in casual clothes came in. She was tall and wore a black skintight suit. She was wearing a gray trench coat, white leggings, and slippers.

Her facial features were delicate, but her eyes were bright and sharp. Her smile made her look mature and soft.

"Ah Chen. Why are you back?" Zhou Tian was surprised and puzzled.

Her daughter's work was something she and her husband could not understand. Only her father knew about it.

It was just that she had few holidays and would inform them in advance before she came back.

"Uncle Mu, Aunt Wen, long time no see. You are so loving and young," Yu Chen greeted first.

"Ah Chen. Just like your father, you can talk well," Wen Jia smiled gently.

"Oh right, this is Aunt Wen's youngest daughter, Tianen," Wen Jia said to her daughter, tilting her head, "Sweetie, this is the elder sister of the Yu family, Yu Chen."

The purpose of Yu Chen's return was to see Mu Tianen. She smiled but looked at her with probing eyes.

Her first impression was she was cute. How could there be such a cute girl?

Her pair of bright eyes looked innocent, clear, and simple. It looked as if she could see through a person's heart at a glance.

"Hello, little sister Tianen."

"Hello, big sister Yu Chen."

Zhou Tian asked Yu Chen to sit down, "Ah Chen, you haven't answered my question."

Yu Chen shifted her gaze away from Mu Tianen's face and looked at her mother, "Someone told me that I was about to have a cute and powerful sister. Of course, I have to come back and meet her."

"Ah Yan, right?" After thinking about it, other than her family, only Leng Yan could contact her daughter.

Speaking of Leng Yan, Mu Tianen's eyes lit up even more.

Yu Chen crossed her legs, "It's Ah Yan. He has been telling me his fiancee is cute. I came back today because I have a holiday."

Zhou Tian thought of how Mu Tianen was the first to notice her daughter coming in, "Ah Chen, Tianen noticed before you came in. She also knows martial arts."

"Really?" Yu Chen sat up straight and looked past her mother to look at Mu Tianen. Her eyes were filled with excitement as she smiled faintly. She wanted to go home and take a look at her sister. If her little sister knew martial arts, she would be energetic.

"Tianen, is that so?"

Mu Tianen nodded obediently.

Yu Chen stood up and walked to Mu Tianen, "Little sister, let's spar."

Yu Chen's anxious look made Zhou Tian unable to take it anymore. She raised her hand to her forehead. Mu Zongwen and Wen Jia, on the other hand, were shocked by Yu Chen's anxiety. Then, they burst into laughter. Because Yu Chen had called her sister, which meant she agreed to let her mother acknowledge this goddaughter.

Mu Tianen was also interested. So she did not refuse and went out with her.

However, the two didn't make it. Yu Yan, who walked from the corridor, called out, "Ah Chen, why are you back? Where are you taking Tianen?"

"I'm going back to take a look at my sister. Now, I'll take her out for a walk," Yu Chen said.

Yu Yan knew his daughter well, "Seeing your sister is true. Taking her out for a walk is not. Don't go. Your grandfather should be here. Go in and wait."

Yu Yan could be serious about Yu Chen but not Mu Tianen. He smiled and said, "Tianen, let's go in."

"Alright," Mu Tianen was obedient toward respected elders.

Yu Chen could only go back in disappointment and immediately felt bored.

Seeing this, Mu Tianen whispered to Yu Chen, "Sister Yu Chen, I graduated. I will be free before September."

The disappointment on Yu Chen's face disappeared.

Seeing Yu Yan come in with two people, Zhou Tian breathed a sigh of relief. It was still her husband who could control her daughter.

After that, Yu Chen and Mu Tianen sat on the side and chatted.

The four parents were also happy to see this.

Zhou Tian and Yu Yan were also quite surprised. They knew their daughter well.

She looked easy-going but was not easy to get along with. What she liked was different from the other girls.

Other girls were gentle and quiet, but she was not interested in any interest that a lady liked.

Instead, she liked the things that boys liked. She was good at sports since childhood. She liked sports. One time, she went to the Leng Clan. Well, in the end, she decided to become the Leng Clan's disciple and learn martial arts.

She didn't have many friends of the same age, and Leng Yan was the her best friend because their hobbies were the same, and they were also people who liked to compete.

Even Mu Tianyu and Yu Chen did not have much to talk about. It was not about their characters. Rather, with different interests, they had nothing to talk about.

They were worried their daughter would not agree to let them take Mu Tianen as their goddaughter.

"Ah Jia, Tianen looks like a little angel. That's great," Zhou Tian looked at Wen Jia with a smile.

"Yes, she is my angel," Wen Jia looked at her daughter who was happily talking to Yu Chen.

Her daughter had few friends. She had been back for a year but only made two friends.

They were also worried Yu Chen would mind. But now, it seemed they thought too much.

Yu Chen and Mu Tianen suddenly stopped talking and looked outside at the same time.

A trace of surprise appeared in Yu Chen's eyes. People coming here were at least fifty meters away. Mu Tianen could sense them, which meant her strength should be not bad.

"Everyone is here."

A deep voice came from the door. The four of them looked up.

An old man in a well-fitting gray suit came in. Everyone stood up to wait.

Yu Jinye looked around with a serious gaze and looked at the pair of big eyes. She looked at him curiously.

"Dad, this is the youngest daughter of Zongwen and Ah Jia, Tianen," Yu Yan introduced.

"Yuan Qing's disciple," Yu Jinye nodded and sat down with a gentle expression on his stern face.

"Sweetie, call Grandpa Yu," Wen Jia said to Mu Tianen.

"Hello, Grandpa Yu," Mu Tianen said as she walked forward.

Mu Tianen was quite curious about him. His hair was gray, but his eyes were still sharp and spirited.

He also knew her Master. Mu Tianen immediately let down her guard.

"Good child, sit."

When his son came back yesterday, he told him about Mu Tianen. He also mentioned she was Yuan Qing's disciple. Yu Jinye was interested and squeezed out some time to meet her. When he saw his granddaughter had also returned and was sitting beside Mu Tianen, a strange look appeared in his eyes.

"Ah Chen. Are you so free?"

"Grandpa, no. I'm busy," Yu Chen immediately looked away, afraid her grandfather would assign her a task again. Although she had no complaints, she was now more interested in this new sister, so she did not want to leave.

Zhou Tian asked the servant to bring up the new tea.

Wen Jia looked at Mu Tianen. The latter stood up and walked to Zhou and Yu Yan. She took the teacup handed over by the servant and handed it to Yu Yan and Zhou, "Father Yu, Mother Zhou, have some tea."
