"You think too much, I'm just back to do things, I don't want to do that shy thing with you. Lilith's face turned even redder when she saw him say this, and even though the two had been together for so long, she couldn't help but have her heart beat faster whenever a man teased her.

Roger approached her, hugged her and walked to the big bed: "Isn't it, I think too much, we'll know if we've done it." "Ah, no, it's ...... in broad daylight now"

The woman struggled in the man's arms, but in the next second, all her words were blocked by the man's hot kiss, but in a moment, a blushing pant sounded in their room.

Since Song Fangfei figured out that Roger was not a crosser, she didn't bother him, but stayed in her room and waited for Mona to reply.

But sometimes, you don't go to him, but someone else will come to the door in person.

"Why are you here again? You're not afraid that your family will be jealous. Song Fangfei looked at Roger who appeared, although this man is very handsome, but he is definitely not his favorite type, not to mention that he is still a person with a partner.

Roger laughed, "No, she's not that stingy." "Besides, even if the little female is angry, he just goes back and loves her well.

"Well, what are you looking for me?" Since this man is not worried, what is she worried about?

Roger thought the little female was very clever and wanted to talk to her about these things. So they came looking for him, and the two walked out, and then he pointed to a three-wheeled driveway: "Do you know how this kind of car is made?"

Song Fangfei glanced at it and said, "It's very simple." Then I explained the method of making it, as well as the principle of Balabala. Roger looked at her in shock and thought that this little female was really powerful.

"Is there a way you can make these cars even better?"

"Absolutely. In fact, in order to make the car powerful, it is necessary to solve the material problem and the energy problem. Instead of relying solely on manpower, as long as the car does not rely on manpower, then they will become very powerful. ”

Song Fangfei thought of modern cars, trains, airplanes, first of all, their manufacturing technology is very superb, but it is not just iron that can be solved, and energy problems, oil, and electricity...... If she had these things, she could have made them.

But now that she's looking at it, there's nothing, so it's basically impossible to make something that modern. But since this man asked herself, she still had to explain a thing or two.

"And what kind of energy is so powerful?" asked Roger, very studious.

Song Fangfei then told him about those things. Roger didn't know what it was, but he knew that if they could find it, maybe the valley would be even more powerful in the future.

"Actually, your patriarch should know these things, and I know very little......" After finishing speaking, Song Fangfei was still very modest.

After talking to the little female, Roger came to her every day, because she felt that the female knew a lot and had new insights. This intrigued him.

Seeing that his male was excited to find Song Fangfei every day, Lilith had nothing to do, and she couldn't be jealous or angry. But whenever she saw Roger and Song Fangfei spending more time than herself, she still felt very uncomfortable.

She wanted to stop it, but she found that she couldn't say anything, because they talked about messy things, she didn't understand them at all, she wasn't Mona, and she knew very little about things.
