If Bai Xiaodie knew in her afterlife that her daughter had become such an outstanding and intelligent person, she would probably be very happy.

"Uncle Master, what are you talking about? Why do we have to be so distant with each other?" Lin Jiuxi decided to persuade him, "It's not convenient for you to go out alone. Why don't you follow me back to Qinzhou? Then we can have someone to take care of us. Even if we are discussing medical books, you need someone, right?"

Bai Hengqiu still shook his head stubbornly, "No need. I think I've been trapped for many years, and I should go out for a walk. I can get to know more people and also treat more people. There are wars all over the world now, and many people don't have money to buy medicine. I can help them and improve my medical skills."

Lin Jiuxi's attempts to keep him were in vain, so he could only let him go.

Lin Jiuxi and Linglong returned to the room. Linglong took out a brocade box, inside which was a small square seal.

"I promised you before, if you don't get hurt and rescue the people, this Linglong Pavilion will be yours."

Lin Jiuxi was shocked, she had never thought about Linglong Pavilion before. Even though Linglong had offered to bet with Linglong Pavilion, she had never thought about really getting Linglong Pavilion. She agreed just to make Linglong give in.

"As we agreed, I'll only stay for a month. After a month, I'll pay you back." The mechanic said to Linglong.

The latest chapter of this novel will be published on 6>@/9 Book# Bar. Please go to 6>@/9 Book# Bar to read it!

Linglong raised her hand and patted her head. "Okay, then you can only use my old arms and legs to take care of you for a few more years."

No matter how good your kung fu is, you are still afraid of artillery shells! Linglong smiled coldly, "What do you think?"

Lin Jiuxi was a little surprised. This man didn't look like a king at all. He looked no different from a beggar on the street, just as dirty.

I didn't expect Linglong to be serious about it.

Lin Jiuxi did not dare to show any contempt in his heart, and walked over to introduce himself to Tian Wenyuan.

Lin Jiuxi was unsure, so he quickly pulled Linglong's hand and said coquettishly, "Aunt Linglong, please. With the help of the mechanic, I can improve these weapons faster, which will also be helpful to Linglong Pavilion. It can also end this war faster and help more people."

It seems to be true.

…

"But I really can't accept it! I have never thought about Linglong Pavilion, and please don't mention it again. I won't agree to it." Lin Jiuxi refused righteously.

Linglong nodded, "Yes, now it seems that I do have good vision."

"Aunt Linglong is not old. In my eyes, Aunt Linglong will always be eighteen." Lin Jiuxi flattered with a smile.

Just as Linglong said, if he had the help of someone like a mechanic, then his ability to use and modify gunpowder would be greatly improved.

Linglong introduced him to Lin Jiuxi with a smile, "This was Tian Wenyuan, the former ruler of Yeyou Country. He was a lazy person who loved to tinker with mechanical things. He passed the throne to his son when he was only twelve years old. Now he has traveled around the world and has accumulated some skills."

"Oh, really? You don't want to find that mechanic anymore? If you get Linglong Pavilion, you can quickly find all the mechanics in Yeyou Country. Can't you complete what you want to accomplish faster?" Linglong said temptingly.

"Oh, didn't I say that Aunt Linglong, you will stay young forever?"

"No, no, I don't want Linglong Pavilion. I never thought about Linglong Pavilion or anything like that. I just wanted to rescue my uncle." Lin Jiuxi said sincerely, "Aunt Linglong, you have helped me so much. I don't know how to thank you. I can't accept Linglong Pavilion no matter what!"

After hearing her introduction, Tian Wenyuan snorted softly but did not refute.

The man had messy long hair and his body and face were dirty. It looked like he hadn't taken a bath in a long time. But the bag on his back was full of scrolls of calligraphy and paintings.

Speaking of mechanics, Lin Jiuxi's eyes lit up.

Linglong smiled and said, "You don't have to be shy about it. This is how it is. I have already decided on it."

"Alas, kid. I have decided from the beginning that Linglong Pavilion is yours." Linglong said, "Do you really think I have such good intentions? Even if I do, I don't have that much time to accompany you."

By that time, others are still struggling on the battlefield with cold weapons, and their own army can be directly packed with hot weapons! It can be said that hot weapons against cold weapons are simply a dimensionality reduction attack.

Linglong was efficient and resolute in her work. Within two days, she had someone bring a mechanic to Lin Jiuxi.

But she still hesitated and shook her head, "If I really don't want to take over Linglong Pavilion, Aunt Linglong, will you still help me find this mechanic?"

This caused Linglong to snort and laugh, "If I stay eighteen forever, I will become an old monster."

"Aunt Linglong planned to train me to take over Linglong Pavilion from the beginning?" Lin Jiuxi felt a little surprised. Although she really didn't want to get Linglong Pavilion, she still felt proud to be recognized by Linglong.

"You're just a little yellow-haired girl, and you want to work in mechanics? I'm afraid you're not here to amuse me." Tian Wenyuan said disapprovingly.

"Of course not. There are so many ways to entertain ourselves in this world. No matter how willful I am, I can't ask a king to entertain me. I invited you here because there are things I want to discuss with you." Lin Jiuxi said as he spread out a rough diagram of a timed-detonation bomb.

Tian Wenyuan frowned as he looked at the compact blueprint, pointed at the round object and asked, "What kind of mess is this?"

"This is called a gear. The gear can drive the chain to rotate, causing the entire internal device to rotate. I also set a spring here to tighten the elastic force of the spring to bring a certain amount of power to the gear, so that the timing can be completed." Lin Jiuxi introduced his ideas to him and also pointed out his shortcomings. "It's just that I haven't figured out how to ensure a sufficient time constant?"

Tian Wenyuan looked stunned.
