Transmigrated as an old lady, she wreaked havoc and brought down the entire villain's family.

"This...isn't this what Grandpa wrote in his notes?" Qin Yansen asked incredulously.

Lin Qingqing pressed further, "Exactly the same?"

Qin Yansen's expression was solemn: "Yes, and this is the result of my grandfather's own research. The notes have never been passed on. Only our family has seen them. How could that professor know about these things?"

Lin Qingqing: "Is it possible that he did the research himself?"

Qin Jingxu's expression was also very serious: "He has never even touched a chip before, so he has no way of getting any research results."

Based on this analysis, Lin Qingqing guessed that there was only one possibility.

That means Old Man Qin may have left a copy of those notes and materials for his illegitimate son.

"That's too much, too much!" Lin Qingqing looked down at the contents of her notebook, clenching her fists and gritting her teeth.

She turned to look at Qin Yansen and asked, "Did you see his photo when you were investigating him?"

Qin Yansen was silent for a moment, then looked up and met Lin Qingqing's gaze: "I've seen... him..."

Lin Qingqing readily picked up where Qin Yansen left off: "He looks a lot like your grandfather, doesn't he?"

"Ah."

“I suspect he is your grandfather’s illegitimate son.”

"...I had the same thought." Qin Yansen was worried that saying it would upset his grandmother, but to his surprise, his grandmother seemed quite accepting, so he spoke his guess without any reservations.

After all, it was all too much of a coincidence.

Qin Yansen closed his notebook and said seriously, "I'll arrange to meet him tomorrow to talk."

Lin Qingqing immediately said, "Let me do it! I'll see what his purpose is. If he's innocent, that's best. But if he has ill intentions towards our Qin family, I will never let him go. As long as I live, I will never let him set foot in the Qin family or take away even a tiny bit of what belongs to you!"

She will personally protect her own child!

She can't always have her grandchildren protecting her.

Let this octogenarian grandmother venture into this tiger's den!

Qin Jingxu, who had been silent until now, suddenly spoke up: "Grandma, you can leave this to us."

Lin Qingqing patted Qin Jingxu's arm: "No need, Grandma will come personally. This week, Grandma will definitely show him what ruthlessness is! She'll make him hesitate to approach the Qin family and give up completely! You can rest assured that Grandma will handle things!"

Qin Yansen earnestly reminded him, "Don't be fooled by him and spend all the money in your pocket on his courses."

"Don't worry, absolutely not. I'm very rational. I will never be soft-hearted just because he looks like your grandfather."

The day after Lin Qingqing made her promise, she swiped five thousand yuan.

Don't ask, the answer is that you bought the course.

Lin Qingqing didn't want to pay for it either, but Qin Jin said that for more detailed information, they could follow his WeChat official account to learn more, which could also help them with their studies.

She wanted to know the extent of Qin Jin's knowledge about chips and whether he had made any other research, so she decided to buy his course.

They studied while simultaneously gathering intelligence on the enemy.

Yang Jiaoyun didn't come today.

Despite the principal's talk to Qin Jin yesterday, saying that Yang Jiaoyun's family was not to be trifled with, Qin Jin remained firm and resolute in his stance. The principal had no choice but to humbly explain the situation to the Yang family.

On one hand, he's incredibly wealthy; on the other, he's young and promising. He's China's first professor specializing in brain-computer interfaces—neither of them is someone to be trifled with.

As Lin Qingqing placed her order for the course, she thought to herself, "He really is a course seller."

Let her see if this illegitimate child is really using the things left by Old Man Qin to pretend to be a ghost and fool people.

If that's really the case, she plans to expose Qin Jin without hesitation, ruin his reputation, and make him not only unable to use the old man's things to swindle and cheat people anymore, but also let him know that the Qin family cannot tolerate people with ulterior motives!

Lin Qingqing had a very clear plan in mind, and a smile slowly crept onto her lips.

Sitting on the other side, Zhao Siyue got angry just looking at Lin Qingqing!

She stole her man and seduced the professor—what a vixen! She'll make that vixen pay!

Immediately afterwards, she saw a boy staring at Lin Qingqing with a silly grin. The boy was wearing a mask and a hat, so she couldn't see his face, but judging from his simply look, she knew he was another one who was infatuated with Lin Qingqing!

So what if she's a little prettier? She's not bad-looking at all!

Zhao Siyue turned her head away defiantly, secretly plotting something, a sly glint suddenly flashing in her eyes.

After Lin Qingqing finished buying the course, Chen Zhonglun next to her said, "Why didn't you buy the 18,000 yuan course? That would have given you an extra online lesson that night."

"I'll just buy the cheapest one first and see how it goes. If the course content is useful, then I'll buy the more expensive one." Lin Qingqing had promised her grandsons that she wouldn't spend money on courses. She already felt guilty about spending five thousand yuan; if she spent any more, she felt like she would be contradicting herself.

But nothing ventured, nothing gained. How could she know if Qin Jin truly possessed the skills if she didn't take the bait?

"Oh, right, this is what I brought for you." Chen Zhonglun took out three boxes of immune-boosting nutritional supplements from his bag and handed them to Lin Qingqing. "This can boost immunity. It works even better when taken with cold medicine. My assistant bought it for me before, and it worked well."

"No need, thank you. You can drink this anytime, you can keep it for yourself."

"Just take it, don't be so polite with me..."

As the two were pushing and pulling, Lin Qingqing suddenly felt a shadow fall on her head.

She looked up and met Qin Jin's imposing eyes through her thin glasses.

Lin Qingqing smiled and raised the corners of her mouth.

Why do I feel inexplicably guilty?

It wasn't entirely unexpected; after all, he genuinely hadn't been paying attention in class and had been caught.

Qin Jin lowered his eyes and looked at the girl with a sweet smile. It seemed to overlap with the familiar face in his mind, and he couldn't help but be stunned for two seconds.

This is his granddaughter. What is he thinking?

Qin Jin forced himself to pull himself out of his thoughts and slowly curled the corners of his lips: "I see you two are having a great time, it's more interesting than my lectures, so I came to check it out."

"..."

Qin Jin narrowed his eyes slightly, shifting his gaze to Chen Zhonglun's face, and then looked at the nutrient solution in his hand.

His expression instantly darkened, and his gaze became much colder than when he had looked at Lin Qingqing: "Caring for classmates is a good thing, but not during class time. Take it back."

Chen Zhonglun wanted to act like a spoiled young master and retort: ​​"Mind your own business. Even your principal has to treat me with utmost respect."

But then he thought again that he still needed to learn from Qin Jin, so it was better not to offend anyone for now.

Chen Zhonglun reluctantly took back the nutrient solution, thinking he would give it to Lin Qingqing after class.

Then, Qin Jin looked at Lin Qingqing and said, "Go sit in the first row."

Who wouldn't want to date his granddaughter?

They must be separated, one in the first row of the classroom and the other in the last row. Excellent, he was very satisfied with this distance.
