Working part-time during the summer vacation, can you earn tens of billions a month?

The two of them were very busy, and the two were very busy.

"Actually, there's no need to go through so much trouble."

"It's very safe inside the manor."

An Kaiguo shook his head, indicating that it was not necessary.

He could wait patiently until Qin Feng found the killer.

Qin Feng said, "Those killers have many tricks, so it's better to be careful."

Although the police were also secretly protecting An Kaiguo, it didn't mean that he was 100% safe.

"Xiao Feng, I'll listen to you."

An Kaiguo no longer insisted.

"Mr. An, I have a question for you."

"Is the reason why those killers targeted you related to the solid-state battery?"

Qin Feng asked the doubts in his heart.

An Kaiguo put away the smile on his face and nodded.

"Yes."

"During this period, many foreign companies have expressed their desire to invest in Qingfeng International."

"But I rejected them."

In fact, what those companies really like is the solid-state battery developed by Qingfeng International.

Solid-state batteries have great market prospects, so everyone wants to get a piece of the pie.

Some companies even threatened An Kaiguo to hand over the technology of solid-state batteries.

An Kaiguo naturally did not agree.

And the result is that hackers frequently invade Qingfeng International.

Now, foreign forces have directly sent assassins.

The purpose is to make the people of the An family obey and hand over the technology.

Qin Feng frowned, which means that not only An Kaiguo, but also other people in the An family are at risk of assassination.

And An Kaiguo seems to have realized this a long time ago, so he asked the people of the An family to reduce going out as much as possible and not give the assassins a chance.

An Kaiguo continued, "These foreigners are best at robbing, but I, An Kaiguo, don't buy it."

They invested a lot of money in Qingfeng International to develop solid-state batteries.

Even if they have to give up the foreign market, they will never hand over the technology.

"Mr. An, you should pay attention to safety."

Qin Feng admired the old man in front of him.

"I will."

"After saying so much, Xiaofeng, you should go and do your own thing."

"If you need anything, just go downstairs and find me."

Qin Feng said no more and turned to go upstairs.

In the room, he continued to develop the third-generation Skynet system.

He developed artificial intelligence with higher difficulty, and as for the simple ones, they have been handed over to the team in Ningchuan City.

Everything is going on in an orderly manner.

Half an hour later, the robot bodyguard also came to the Anjia Manor.

The name on the ID card is Zhang Tieniu, and he looks like a rough man.

Although he looks taciturn, his IQ is higher than that of ordinary people.

As for combat effectiveness, it is higher than Qin Feng.

Qin Feng is also quite relieved to have such a robot bodyguard to protect An Kaiguo.

Unknowingly, it was time for dinner in the evening.

The door was knocked.

Qin Feng put down his work and went to open the door.

"Qin Feng, it's time for dinner. Grandpa asked me to come up and call you."

An Ya stood outside the door, a little curious about what Qin Feng was doing.

"Okay, I'll be down right away."

Qin Feng did some finishing work and then went downstairs.

During dinner, Zhou Ruonan also came.

Knowing that the An family and Qin Feng were still having dinner, they could only wait outside the hall.

And Zhou Ruonan came this time, in addition to patrolling, but also wanted to see Qin Feng.

Soon, Qin Feng also had a full meal.

Zhou Ruonan called Qin Feng out alone.

"You did a great job this morning. You dug out a foreign spy hidden in Ningchuan City."

This kind of spy is hidden very deeply and is extremely harmful.

If Qin Feng hadn't discovered it, the spy would have continued to lurk.

Qin Feng smiled and said, "I didn't expect there would be spies in Qingfeng International at first."

The other party wanted to steal technical resources, but unfortunately they lost more than they gained.

Zhou Ruonan said, "Later, we followed the clues and found two more spies in Ningchuan City."

"Now they have all been arrested."

Qin Feng also helped them a lot unintentionally.

Qin Feng smiled, "You came here just to tell me about this?"

"There is another thing, it's about the Zhang family."

"There has been no news since Zhang Jun fled abroad, but the Zhang family is almost finished."

"After Zhang Yuting died, several young people in the Zhang family were busy fighting for property."

"But few people in the Zhang family have a clean background. As long as there is enough evidence, the Zhang family will be finished."

Qin Feng did not answer.

In fact

Once Zhang Yuting died, the rest of the Zhang family would not pose a threat to him.

After Zhou Ruonan left, Qin Feng also went back to his room to work.

That night, Qin Feng was busy until more than three o'clock in the morning, and then he went to bed.

At eight o'clock the next morning, he got up to work again.

Even breakfast was brought up by the maid of the An family.

And in the following day, Qin Feng also stayed in the room.

At more than ten o'clock in the evening, Qin Feng, who was working, found that his mobile phone suddenly vibrated several times.

He took it and looked at it, and his eyes immediately turned to the window.

The moonlight was blocked by dark clouds, and the night wind blew, and the trees in the manor swayed left and right.

It was a dark and windy night for murder!

Qin Feng installed a defense software on the mobile phones of all the people in the An family in advance.

Just now, An Kaiguo and An Wenhong's mobile phones were hacked.

Therefore, there is a high probability that the killer is ready to act.

Qin Feng pondered for a while, and then continued to improve the third-generation Skynet system.

Because the robot bodyguard was in the An family manor at that time.

Even if a killer could sneak into the manor, it would not cause any trouble.

It was a little after two o'clock in the morning.

A black shadow climbed over the wall somewhere.

The movement was very fast, like a ghost in the night.

The black shadow stayed in the bushes for several minutes, and after confirming that the surrounding area was safe, it quietly came to the main villa.

There were also bodyguards guarding the manor, but this time period was the most tiring time.

The black shadow chose to act at this time, and the emphasis was on surprise.

He seemed to know the situation of the manor very well and bypassed all the surveillance cameras.

Soon he came to the back door of the main villa.

He was about to climb up from the window, and suddenly, a strong wind came quickly from behind.

The killer's face changed drastically and he hurriedly dodged.

With a "bang", his shoulder was still hit by a punch.

"Shit!"

"I was discovered."

The killer retreated more than ten steps in a row before stopping.

Standing in front of him was a burly man with an expressionless face.

The killer didn't even know how this man approached him just now.

Now that he was injured in the shoulder, it was impossible for him to complete the mission.

So, he could only escape from here and make plans later.

"Go to hell."

The killer took out a pistol from his body, pointed it at the robot bodyguard, and pulled the trigger.

At the same time as the gunshot rang out, the robot bodyguard also moved.

The first shot missed.

The killer gritted his teeth and fired several more shots.

Unfortunately, every shot missed.
