Walking out of the Cloud Sky Tower, Yan Yun did not expect that Chu Yunxi would actually be waiting for him.

"Today is the Mid-Autumn Festival, let's go buy some vegetables! Le Le and Mu Er are at home. " Chu Yunxi said calmly.

Yan Yun raised his head and glanced at her. Although Chu Yunxi's expression was cold, it looked a bit like a well-behaved wife waiting for her husband. Yan Yun was a little worried, but he shook his head and laughed: "I want to go over to Zhang Anguo's house to take a look first."

Chu Yunxi nodded, dismissed the bodyguards that she brought with him, and drove towards Zhang Anguo's home.

It was an old house in an old, inexpensive neighborhood. The car turned left and right before finally coming to a stop.

"We have to get here. We have to walk for a while." Chu Yunxi said to Yan Yun who was beside him.

Yan Yun nodded, on the way, Chu Yunxi told him a lot of things about Zhang Anguo's family. His wife was a lackey, and the only income his family had was his pathetic monthly salary.

His family was ordinary to the point of collapse, yet a great scientist had appeared who was about to push forward the fourth technological revolution of mankind.

Zhang Anguo, what a common name, if not a thousand in China, then it should at least be eight hundred! However, this kind of person had found a way to force the crawling giant dragon, Hua Xia, to fly away.

The path was bumpy and full of holes. After passing through countless alleys and alleys, they finally arrived at a courtyard with a peach tree in front of the gate.

The house was a two-story old building. The white paint on the wall had turned yellow and had condensed into countless pieces that fell to the ground. There were traces of worms nibbling on the old wooden door.

Pushing open the gate, although the courtyard was old, it was still very clean.

"Mom, can you stop crying!?"

"So annoying, just a blockhead like you, Dad. Why are you grieving for him!?" Did he take care of us? "

"Little Yue, if you say that about your dad again, then don't recognize me as your mom from now on."

From the house came the sound of mother and son arguing.

Seeing Yan Yun's slight frown, Chu Yunxi explained: "Zhang Anguo has spent his entire life researching. He doesn't even rest when he returns home from work, so he takes very little care of his family …"

Yan Yun nodded in understanding. If he did not have that kind of crazy research spirit, he probably would not have been able to research the 'Black Emperor' alloy. He was a science maniac, and was similar to Edison and the others back then.

Arriving at the door, Chu Yunxi knocked on it.

"Who is it?" A boy's voice rang out, and then the door opened, revealing a boy of about eleven or twelve years old.

"Big sister, it's you!" When the boy saw Chu Yunxi, he muttered and completely opened the door. At the same time, Yan Yun shot a glance at Yan Yun.

"Boss Chu?" Hurry, come in and make it. Little Yue, quickly go pour some tea. " A lady with wrinkles all over her eyes walked out and wiped her hands off her clothes. After feeling clean, she invited Chu Yunxi in and greeted him.

"Aunt Chen, there's no need to be busy. I came here with a friend. He was a good friend of Uncle Zhang before he died." Chu Yunxi still misunderstood that Yan Yun had a relationship with Zhang Anguo.

"This little brother is …" The woman looked at Yan Yun blankly, she obviously did not think that her husband would have such a young friend.

Honestly, she could not imagine what kind of relationship Yan Yun had with Zhang Anguo, regardless of status or age, the difference between the two was too great. The reason why Chu Yunxi misunderstood her was also because of the agitated Yan Yun had shown when she heard the news of his death.

"My name is Yan Yun, I was Uncle Zhang's good friend before he died." Yan Yun laughed as he reached out to grab the woman's wrinkled right hand.

"Who are you trying to trick!?" My father is old enough to be your father, and he even has friends. " The youth sitting on the sofa curled his lips in disdain.

"Little Yue, what nonsense are you saying! Didn't I tell you to pour tea? " The woman glared at her son, then turned her head apologetically and said, "I'm sorry, the child is spoiled and doesn't know how to be polite."

Yan Yun laughed and shook his head, then went back to the main topic, "Aunt Chen, there's no need to work anymore, I'm working on the research too, I was originally partners with Uncle Zhang, after Uncle Zhang passed away, his research was cut off, I came over to look for more information."

"So it's like that!" A sliver of disappointment appeared in the woman's eyes, then immediately after, disappointment. With her husband's wooden personality, she believed that he really wouldn't have any friends. He had only come for work.

"Aunt Chen, please don't misunderstand. Searching for information is secondary. The main point is to come and see you." Yan Yun explained with a smile, thinking that he was too impatient! It seemed that he couldn't remain calm after encountering such a huge problem.

"Aunt Chen, this is the research institute's comfort fee. Please accept it." After Yan Yun finished speaking, he did not care about Chu Yunxi's surprised expression and handed the black bag to the lady, inside the bag was the hundred thousand dollars that he took out at the last moment.

The woman hesitated for a while, but thinking that it was the research institute's compensation, she did not reject, but when she saw the large pile of bills inside, she immediately returned the bag to Yan Yun in fright.

"This is too much, little brother, don't lie to me. Why would the research institute give you so much money?" The woman shook her head resolutely.

Seeing this, Yan Yun sighed in his heart. How could a mere one hundred thousand yuan be enough to describe Zhang Anguo's contribution? Since he couldn't use the job description to describe the contribution he had made, he might as well change it to another method.

"Aunt Chen, you're really smart. However, although this money is not the research institute's money, it's really Uncle Zhang's own. This is the income from buying stocks with me while he was still alive."

Yan Yun patted his chest and continued to speak: "Aunt Chen, if you do not believe me, I can show you the stocks. We have good luck, and the stock has gone up in price, if you do not believe me, you can ask Boss Chu, it just so happens to be theirs, I think with Boss Chu's identity, you will not lie."

Chu Yunxi was startled, then she nodded her head: "Aunt Chen's promise, is absolutely true."

The woman was stunned by the way the two of them spoke.

"Mom, since they're giving us money, why do you care so much? Just take it. I've always wanted a computer!" the teenager said as he lowered his head to make tea.

"Little Yue, mom is not happy about you acting like this again." The woman turned and looked at her son with a cold expression.

Seeing that his mother was really angry, the young man said with a flattering smile, "Mom, I was just joking. Don't be angry!"

"There won't be a next time." The woman fiercely looked at her son, turned around and continued to push the money to Yan Yun, and said: "Little brother, I cannot take this money, but we believe that you are Old Zhang's friends, and that the draft is in his study. You can look for it yourselves."

Seeing that the woman was so insistent, Yan Yun nodded his head deeply, and under the lady's guidance, they walked into Zhang Anguo's study together.

The study room was a mess, there were a lot of things placed around, but Yan Yun did not seem to be impatient at all, he carefully read through all the manuscripts, all the way until two hours had passed, and even after flipping through all the drafts, he still could not find any information about the "Black Emperor", but he was able to find a letter within the pile of manuscripts.

He did not open it, because the letter was for Zhang Anguo's wife and son.

"Little brother, did you find anything?" The woman asked with a smile when she saw Yan Yun walk out of the study.

Yan Yun shook his head, feeling somewhat regretful, he then handed the letter to the woman.

"Aunt Chen, Uncle Zhang wrote this for you. I found it by the side of the manuscript."

"Oh?" The woman curiously accepted the letter and opened it to read it carefully. After that, under Yan Yun's observation, the woman's eyes became redder and redder, and finally started to cry without caring about her image.

"Aunt Chen, it's good to see you again." Chu Yunxi stepped forward and comforted her.

After a long while, she shook her head and gave the letter to Yan Yun.

"Little brother, you are looking for these! "Although I don't know who you are, but I believe you, these things seem very important. Old Zhang said that he can rely on them to change the lives of mother and son."

At the bottom of the letter was written a series of chemical formulas. It looked very vague, and was only vaguely mentioned.

"Aunt Chen, thank you so much." Yan Yun gratefully looked at the woman. For Zhang Anguo to be able to create the 'Black Emperor' alloy, the woman's support must have been of great help!

"Hehe!" "No need." The woman shook her head nonchalantly.

At this time, Teenage heard his father's letter and ran over curiously.

He snatched the letter and read it. The youth said in surprise: "Ah, I have seen these chemical formulas before."

"Where?" Yan Yun's breathing became hurried.

"Let me think …" The young man unperturbedly touched his head, almost angering Yan Yun to death. Chu Yunxi who was watching from the side laughed, thinking, every time it is just you pretending to be calm in front of others, this time it is your retribution!

"Now that I think about it, I went to the toilet on toilet paper, but I seem to still have some left over." The youth said with a calm expression.

"…" Yan Yun had the urge to knock him down.

"Where's the toilet?" "Quick, take me there."

"Let's go out and take the first bungalow."

"…" Yan Yun walked out of the room with a depressed face.
