Seeing the two people's persistence, Li Xiulan had no choice in dealing with her grandfather and grandson.

"Liu Yang, let's go out and buy new year's goods. Guimei's leg is injured and it's inconvenient to go out. It's just right for his grandfather and grandson to watch Guimei at home." Grandma said to Liu Yang from the side.

Liu Yang looked at Zhang Guimei and nodded.

"Okay, Mom, let's go together."

"I'm going out today to buy some tobacco, alcohol and other things that I need for the New Year. As for the vegetables, I'll buy them separately in two days. There are still a few days until the New Year, so it won't be fresh when I buy them now." Liu Yang said to Li Xiulan.

"Okay, let's go out and buy all the things we need to buy today. It won't be too late to buy groceries in two days."

Before going out, Liu Yang told Liu Cong a few words, then took the car keys and went out with Li Xiulan.

The grandfather and grandson also started a Go battle.

Later, Liu Jianguo's face became darker and darker. He realized that no matter how hard he tried, he could not win against his grandson.

"It's weird, how come I, an amateur seventh-dan player, can lose to you one after another?"

"Tell me! Did you cheat?" Liu Jianguo pointed at Liu Cong and said angrily.

Liu Cong felt a little aggrieved when he heard his grandfather say this about him.

"Old man, don't be slanderous. My mother is watching from the side. I didn't cheat."

Liu Jianguo, who had lost several games of Go in succession, was a little angry. He became even more angry when he heard Liu Cong calling him an old man.

"Grandson! Who are you calling old man? I am your grandpa!"

As he said that, he looked around the house, looking for something.

Liu Cong felt a little bad when he saw his grandfather's behavior and thought: "No, this old man may be looking for something to hit himself."

Then, Liu Jianguo stared at the feather duster on the table not far away.

After seeing this, he immediately got up and hit Liu Cong with a feather duster.

Seeing this, Liu Cong quickly apologized.

"Grandpa, I was wrong. I will never call you old man again."

What Liu Cong was afraid of was not that his grandfather would hit him with a feather duster, but that he would have a heart attack because of his anger.

The Chinese New Year is almost here, and if his grandfather is hospitalized because Liu Cong calls him an old man, then his father will have to remove his arm.

Zhang Gui, who was watching TV next to him, felt very happy when he saw the old man and the young man. He thought to himself: "The relationship between the grandfather and grandson has finally eased a lot."

After dinner in the evening, Liu Jianguo refused to admit defeat and insisted on playing Go with Liu Cong. Unexpectedly, he still lost.

After returning to his room,

Liu Cong played Go until one or two o'clock in the morning before going to bed. After playing ten games, he still won all the games.

Originally, Liu Cong went from being ranked among the top 1,000 in the region to being ranked within 100 in an instant. His original score of 550 was reduced to 950 because of his ten consecutive victories.

After playing ten games, Liu Cong looked sleepy. He turned over on the bed and fell asleep.

Early the next morning, the door was knocked.

"Grandson Turtle, don't sleep. Come out and play chess with me."

Liu Cong turned over with difficulty and pretended not to hear. However, when his grandfather heard that there was no movement inside, he was unwilling to give up and continued to knock on Liu Cong's door.

Liu Cong really couldn't resist his grandfather's knock on the door, so he casually agreed.

"I understand, Grandpa, I'll be right over."

After Liu Cong said this, Liu Jianguo stopped knocking on the door, and instead told Liu Cong to hurry up.

Twenty minutes later,

Liu Jianguo knocked on the door again.

This time, Liu Cong couldn't bear it anymore, hurriedly put on his clothes and got up. After opening the door, Liu Jianguo was preparing to ring the next time.

"Grandpa, stop knocking. Can't you get me up?"

In this way, Liu Cong dragged his tired body to wash up.

After breakfast,

Liu Cong was forced by his grandfather to play two more games of chess. Without exception, he lost in both games.

This made Liu Jianguo depressed. Even at this time, he himself doubted whether his chess skills had deteriorated.

Just when Liu Cong was about to play a game of chess with his grandfather, Liu Cong's cell phone rang.

The ringtone seemed like a life-saving straw, and he happily answered the phone.

At this time, a rough voice came from the other end of the phone.

"Hi, hello, do you need Shenbao tablets?"

Liu Cong was a little confused by these sudden words. He came to his senses and immediately refused: "No need."

Just when Liu Cong was about to hang up, the other party said hurriedly: "Don't hang up. It's okay if you don't need to buy some for your parents or relatives and friends."

"Our Shenbao tablets can be taken by people as old as eighty years old and children as young as ten years old..."

The other end of the phone was constantly selling to him, and Liu Cong was getting a little impatient.

With a snap, he hung up.

Liu Cong put down his cell phone and said to Liu Jianguo: "Keep going, it was a sales call just now."

Just as Liu Cong was about to make his move, the phone rang again.

After receiving the call, it was still the same sales call as before, and Liu Cong hung up without talking for a few words.

Before Liu Cong's child landed, the phone rang again. This time Liu Cong was a little impatient.

"Hey, there's no end to this."

Liu Cong didn't even look at it and directly answered the phone.

"I don't buy Shenbao tablets, no! I'm healthy, don't call me anymore." Liu Cong said loudly.

"What kind of kidney treasure pill is it? It's me."

Liu Cong came back to his senses and seemed to feel that the voice was somewhat familiar.

"headmaster?"

"It's not who I am. What did you just say about Shenbao tablets?"

Hearing what the principal on the other end of the phone said, Liu Cong was a little embarrassed, and then explained: "There was a sales call that came to me several times just now. I thought it was him this time."

"Oh, so that's it."

"Classmate Liu Cong, do you have time now?"

"Our team's research and development of lithography machines has now reached a bottleneck period. This information was created by you. You should be more familiar with the manufacturing steps of lithography machines than anyone else."

"I would like to invite you to come over and give me guidance. I wonder if you are busy right now." Principal Zhu said.

How could Liu Cong dare to slack off on such an issue that concerns the country? He agreed to the principal without even thinking about it.

After Liu Cong hung up the phone, Liu Jianguo asked curiously: "Is the principal on your phone the principal of your junior college?"

Hearing what his grandfather said, Liu Cong didn't know how to answer his grandfather for a while.

Then, an idea flashed in his mind, and Liu Cong said: "Oh, the principal is a nickname of my friend. He has his birthday today and invited me over for lunch."

When Liu Cong said this, Liu Jianguo finally understood the general situation. Then he waved his hand and said, "Go, grandpa doesn't want you to accompany him."

After Liu Cong walked out of the door, he hurried towards Huaqing University.

Twenty minutes later,

Liu Cong arrived at the gate of Huaqing University.

This time, the security guard did not embarrass him, but let Liu Cong go in directly. After all, he now also had a Huaqing University student ID card, which was given to him by the principal himself.

Arriving at the Huaqing campus, Liu Cong followed the location information provided by the principal on his mobile phone to the bottom of the science and technology building.

Looking at this egg-shaped oval building, Liu Cong entered without hesitation.

Just when Liu Cong wanted to enter the laboratory, he was stopped by two men holding guns and wearing armed police uniforms outside.

"Do you have a work badge? If not, please get out now, otherwise don't blame us for being rude."
