Lin Qin looked at him with a half-smile.

"Then why did you come? You could have just sent someone over."

"Didn't I tell you? The old man is very watchful. If he finds out I didn't come, he'll break my legs."

"You're partly to blame too. Who told Boss Lin to be so outstanding? He's been different since he was little. We brothers are just relegated to being the foil, getting lectured by our father every day."

Lin Qin patted him on the shoulder.

"Just because you said that, if I can buy some of these rain bombs today, I'll bring you one."

"You're so good to me?"

"Of course, you take such good care of Keke, so it's only right that I repay you."

Upon hearing this, Xu Mu's face instantly darkened.

The atmosphere between the two men became somewhat tense.

“Keke is my friend, it’s only right that I take care of her. On the contrary, you, a married man, don’t you find it ridiculous that you keep bothering Keke every day?”

Lin Qin still smiled confidently.

"We'll soon find out who's the laughingstock. Jin Shu and I have already filed for divorce. Our marriage will be automatically dissolved in a month. I'm single now."

Xu Mu wanted to say something, but he couldn't utter a single word for a long time.

In this relationship, the one who isn't loved is the clown, and Xu Mu knows perfectly well that Ke Ke likes Lin Qin.

The two looked away, and just then someone finally entered the office.

"Sorry to keep you all waiting. My name is Guo Xu, and I work in the factory's R&D department. Our factory is quite busy today, so I will now give you a tour of the factory facilities."

Everyone came under the guise of visiting and learning, so being led around the workshop wasn't a problem.

After the tour, everyone's eyes lingered on the workshop, seemingly searching around.

Guo Xu was well aware of their intentions, so he took the initiative to speak.

"Look over here, everyone. This is the independent workshop of our chief designer, chief engineer, and the newly appointed head of the R&D department."

Upon hearing this, everyone's eyes immediately lit up.

What was once an ordinary little house now resembles a historical site, where even a single screw is worth examining repeatedly.

Among the visitors were engineers from other companies, who quickly noticed the blueprints hanging on the wall of the independent workshop and couldn't help but ask questions.

"Are those drawings the design sketches used when developing the rain-reducing bomb?"

Guo Xu nodded with considerable pride.

"Yes, our teacher has a habit when designing sketches: he will take whatever is at hand and write it down."

It's not just a piece of paper; tables, walls, floors, and other surfaces can all become design panels for teachers.

Therefore, all the sketches displayed before you now are the initial drafts of this rain-dropping projectile research.

Several designers crowded to the front to take a look. After seeing the sketches clearly, everyone couldn't help but lean forward, their eyes wide, and they couldn't help but exclaim in admiration.

"Incredible, absolutely incredible."

"This is hardly a sketch. How could someone present all their ideas so completely and in such detail in the first stage?"

"This is amazing. Although I know the saying that there are always people more capable than you and the sky is always higher than the sky, after seeing these sketches, I suddenly feel that I am not worthy of being an engineer. Compared with this teacher, my past thirty years have been like children playing house, completely joking around."

"Excuse me...excuse me, may I take a picture?"

Some people couldn't help but complain.

"I'm already being generous by letting you see it for a couple of seconds, and you still want to take pictures? How can you be so greedy?"

The other party immediately felt ashamed and was about to apologize when Guo Xu generously said something.

"Go ahead and take pictures, it doesn't matter. The teacher said that wisdom needs to be shared. She can't guarantee that her designs are without any flaws, so she told us not to do anything to cover or protect her studio."

"Feel free to film if you want to see or learn."

"This is a true master! I am truly in awe of him!"

"What are you standing there for? Take pictures! Take more pictures and you'll learn more!"

Industry experts were taking photos like crazy, while the bosses who didn't know anything stood outside, not understanding the details but knowing it was impressive.

Lin Qin stood outside looking inside.

Although he is the boss, he is also somewhat of an industry insider, so he can naturally understand the value of these drawings.

If we were to use a painting as a metaphor, the status of these sketches on the wall and floor at this moment would be almost no different from that of Leonardo da Vinci's Mona Lisa.

It's even more perfect than the illustrations in the textbooks.

He also took out his phone and took a few pictures carefully. When he turned around to look at them closely, he suddenly realized that the papers on the table looked familiar.

He stood in the corner, zooming in on his phone screen to examine it closely.

This is a piece of paper with a gold outline and light-colored prints on the bottom. To an outsider, it is just an antique-style piece of paper with a medieval feel. But to Lin Qin, this paper is exactly the same as the paper in the notebook that Yu Keke gave him when he returned from Europe not long ago.

The notebook was bought by Keke from a niche shop in a medieval European city. The shop specializes in custom-made commemorative notebooks, where all the patterns and decorations are customized by the customer.

Therefore, there is absolutely no possibility of coincidence.

Lin Qin was afraid he hadn't seen it clearly, so he went closer to take another look, and this time he could see it clearly.

It was indeed the kind of paper that Keke gave him, the kind that comes from the notebook.

This kind of paper is only available to him and Keke, so how did it end up here? And how did it end up with the precious first draft of the rain bomb?

Lin Qin's thoughts were a bit chaotic, and he had many guesses in his mind.

He couldn't help but ask Guo Xu.

"Excuse me, what is the surname of the teacher you mentioned?"

Guo Xu frowned, his mind reeling with alarm bells.

Teacher Jin's identity is currently classified as top secret within the entire organization; anyone who leaks even a single word of it will be in serious trouble.

The reason for doing this is to protect Professor Kim's personal safety. After all, if other countries can't get such an outstanding talent, they will definitely destroy him.

Therefore, Guo Xu spoke in an unfriendly tone.

"Why are you asking this? This involves state secrets, I'm sorry I can't tell you."

Upon hearing this, Lin Qin, no matter how confused and conflicted he was, refrained from asking any further questions.

Over the next hour, the factory added two more rain bombs, which were sold through an auction.

They were later sold for 60 million and 73 million respectively.

No one dares to say anything about such unreasonable market pricing; after all, being able to buy a treasure that is priced but not available is already a blessing.

The buyer of that 73 million rain bomb was Lin Qin.

But he wasn't very happy at the time; he just hurriedly got into the car and went home.

When he got home, he quickly took out his notebook from the drawer in his study, opened it, and flipped through it randomly. Sure enough, a page was missing!
