Douluo's strongest demon system

"Boom boom boom,,,"

"Come in!" Hearing the knock on the door, Xiao Luo shouted to the door.

Opening the door, the ghost walked in!

"Luoluo, your ghost grandpa, I saw a good thing on the street today. I thought it was pretty good, so I bought it for you!" With that said, the ghost took it out of the soul guide.

After taking a closer look, I saw that it had a T-shaped shape, with a horizontal piece like a propeller, and a small hole in the middle, into which a straight bamboo stick was inserted.

"Haha, Luoluo, you definitely don't know how to play!" He said and began to demonstrate. When the ghost saw it, he twisted the bamboo stick with both hands, then released his palms, and the stick spun and flew up.

"Haha, how about it, it's amazing!" He said, using his soul power to take it back, and then handed it to Luo Luo.

"Here, take it and play with Nana! Cultivation is important, but you must know how to balance work with rest!"

"Well, I understand, thank you, Grandpa Ghost." Xiao Luo thanked him as he reached out to take the small toy handed over by the ghost.

"Haha, it's okay. Grandpa has something else to do, so he's leaving first!" With that, he walked out the door!

"Well, goodbye Grandpa Ghost!"

Watching the ghost leave, Xiao Luo then looked at the small toy in his hand and took a closer look. Isn't this the bamboo dragonfly from his previous life? Nana must have never played with it before, so let's go play with her!

……

"Nana, Nana!!"

"Luoluo? What's wrong? What happened? You are so anxious!" Hu Liena slowly walked out of the room when she heard Xiao Luo calling her.

"Nana, Grandpa Ghost bought me a toy and asked me to take you to play with it." Xiao Luo said.

"Toy? Great! You come in first and wait for me for a moment. Judging from your irritable appearance, you must not have told the teacher. I will report it to the teacher, otherwise the teacher will be anxious if he doesn't see us!" After that, Then walked to the Pope's Palace!

Watching Hu Liena leave, Xiao Luo shook his head helplessly, "This little girl!"

If you think about it carefully, although Bibi Dong does not have a husband who loves her and takes care of her, she does have a sensible and filial disciple like Hu Liena! During the decisive battle at Jialing Pass, it was Hu Liena who blocked Bibi Dong with her body, vowing to the death not to let Tang San hurt Bibi Dong.

Hu Liena's room is pink in color. There is a huge bed in front of her. The gorgeous decoration makes people feel like they are in a fairy tale kingdom. On the other end of the bed is an exquisite dressing table. There are all kinds of cosmetics, and the floor-to-ceiling windows next to it are shining with dazzling sunlight. The sunlight shines on one end of the bed, making people feel extremely warm when looking at it.

"Hu Liena, Hu Liena, grow up quickly!"...

It has been two years since Xiao Luo came to Wuhun Hall. Apart from Bibi Dong, Juhuaguan and Gui Mei are almost the people who love Xiao Luo the most. Whenever they have time, they take him out to play or come back from doing tasks outside. , they would bring him toys or delicious food every time. Juhuaguan and Gui Mei had no children in their lives. In their eyes, Xiao Luo was already regarded as their own grandson.

It's ridiculous to think about it. When Sword Douluo and Bone Luo died, many people felt sorry for them. They were Ning Rongrong's grandfathers! But when Juhuaguan and the ghosts fell, I don’t know how many people applauded and cheered there, but who could have imagined that they were also Hu Liena’s grandfather!

With a slight sigh in his heart about their experience, Xiao Luo lay down on Hu Liena's bed, picked up Hu Liena's pillow, and greedily sucked the faint fragrance on the pillow...

……

"Luoluo, let's go! Fellow teacher," Hu Liena happily opened the door, but the scene in front of her instantly broke her guard! How shameless can a man be? Hu Liena's three views were refreshed again.

"Um, um, Nana, you're back!" Xiao Luo blushed and immediately put down his pillow.

Hu Liena "..." I'll give you a look and feel it for yourself!

"Hey!" Xiao Luo immediately jumped out of bed, threw Hu Liena up, and then pressed on top of her.

"Nana, baby, the smell on the pillow is not as strong as the smell on you, baby!" Xiao Luo lowered his head and kissed Hu Liena's collarbone. His hands were not idle, and he touched her waist expertly.

"Luoluo, if you do this again, I will go to the teacher and file a complaint!" Hu Liena said helplessly.

"Hey, thirty minutes!"

……

Thirty minutes later, Xiao Luo reluctantly let go of Hu Liena. Hu Liena glared at Xiao Luo, and then put on her clothes in despair. Now, except for the last step, Xiao Luo did everything they should do and shouldn't do.

"What kind of look are you looking at? You won't lose a piece of meat if you touch it." Xiao Luo said with a joking expression on his face.

"roll!"……

So after another half an hour, the two of them set off!

……

"Luoluo, what is the name of this gadget? How do you want to play with it?" Hu Liena asked.

"This one is called Bamboo Dragonfly. Let's play like this..."

"Haha, it's flying! It's flying!!" Hu Liena shouted happily!

"Fly higher, fly higher!!"...

Unknowingly, the afterglow of the setting sun fell on their faces...

"Nana, it's very late, let's go back!"

"Okay, but Luo Luo, tell me, how did this bamboo dragonfly fly up?"

"When the pair of small wings rotate, the rotating blades push the air downward, forming a strong wind, and the air also gives the bamboo dragonfly an upward reaction lift. This lift changes with the inclination angle of the blades, and the inclination angle is large. The lift force is large, and the lift force is small when the inclination angle is small. When the lift force is greater than the bamboo dragonfly's own gravity, the bamboo dragonfly can fly upward." Xiao Luo explained.

"What is it? What is the force and reaction force? And what is the inclination angle? Can it be eaten?" Hu Liena asked without knowing why.

"Hajie, Nana, you are so cute!" He said, and pinched Hu Liena's nose again.

"Luoluo, you teased me again!!"

"Ha ha!!"
