Princess Mumu sat in the cab, her mood was a little nervous, and she glanced back at Nuan Nuan, who showed her encouraging eyes.

Then she followed the method Nuan Nuan taught her and gently pressed the start button.

When the plane started, it shook gently.

Seeing this, the dwarven king looked at the plane nervously, his face full of worry.

Nuan Nuan walked up to him and gave him a reassuring look and told him not to worry.

The plane slowly rose under everyone's gaze, and Princess Mumu was a little scared and clutched the seat tightly.

"Princess Mumu, relax, don't be afraid." Nuan Nuan said loudly.

Princess Mumu controlled the plane to rise slowly, and when the plane rose to a few dozen meters above the ground, she was not so afraid, but her heart became excited.

She stretched her little hand out of the window, shook it at everyone, and shouted, "I'm flying, it's fun." ”

"Mumu, be careful, don't be careless." The dwarven king raised his head and shouted loudly. At this time, he was very excited, and his mood was extremely good.

Princess Mumu followed the method Nuan Nuan told her, and after raising the plane to an altitude of two hundred meters, she controlled the plane to fly forward.

The feeling of flying the plane is very good and exciting, and at this time, Princess Mumu really wants to drive the plane directly and go to the world outside the forest to see.

After flying around in the air, Princess Mumu lowered the plane.

When she got off the plane, Nuan Nuan stepped forward and asked, "Princess Mumu, how do you feel?" ”

"I feel very good, if only I could fly the plane outside in the future." Princess Mumu replied with a smile.

"Hmph, you still want to go outside?" The dwarven king walked over and glared at Princess Mumu.

"Father, don't be angry, I'm just talking about fun, don't take it seriously." Princess Mumu stuck out her tongue at her father.

"Nuan Nuan girl, on behalf of all the people of the Dwarf Kingdom, I would like to express my gratitude to you, with this plane you made, it will be much easier for us to travel in the future, and we will no longer have to worry about the beasts on the ground." The dwarven king thanked Nuan Nuan.

Nuan Nuan smiled and said: "Your Majesty, you don't have to be polite, I have regarded Princess Mumu as a friend, and I am happy to help her people." Next, I will teach you the technology of making airplanes, so that you can learn our technology manufacturing.

Nuan Nuan's technology has always been the first in the class, she has heard and witnessed it since she was a child, and she learned a lot of scientific and technological knowledge from her grandfather.

Next, she told the craftsmen of the dwarven kingdom about the scientific and technological knowledge she knew, and asked them to learn from it.

The dwarven kingdom already has its own set of science and technology, and they learn the scientific and technological knowledge taught by Nuan Nuan, they learn it quickly, as long as Nuan Nuan speaks it, they can learn it quickly.

Nuan Nuan taught them to use solar energy as an energy source, and then the solar panels were made, and when the lights were turned on in the palace, everyone was stunned and felt incredible.

Nuan Nuan also made wooden bicycles, because Nuan Nuan usually makes toy bicycles to kill time when she is fine, but this wooden toy bicycle is a good travel tool for these dwarves.

Nuan Nuan drew the drawings of the construction of the bicycle and taught their craftsmen to make it according to the drawings, and soon the bicycle was built.

Next, Nuan Nuan taught the dwarven craftsmen the art of making toy airplanes, asked them to make their own parts, and then let them install them by hand, and a small plane was built that was almost the same as the original.

In fact, this plane is very simple to build, as long as it is equipped with solar panels as power, the people of the dwarf kingdom also engaged in research on aircraft at the beginning, but they don't know what to use as power, so they didn't study this aspect later.

At the beginning, their ancestors had tied a large animal skin bag to the cart, which made the cart rise several meters high.

Nuan Nuan also let the king visit the flying fish, and when the king was invited to the flying fish, the king was really eye-opening.

The various facilities in the flying fish are very advanced, which the dwarf king has never seen before, and the dwarf king finally couldn't help but exclaim: "Nuan Nuan girl, your human technology is really an eye-opener for me." ”

"We have advanced technology, and we have powerful weapons that are enough to destroy this forest." Nuan Nuan said with a smile.

"Ahh Is there really such a powerful weapon? It's horrible. The dwarven king was shocked, a little hard to believe.

"Father, what are you afraid of, Nuan Nuan girl will not point her weapon at our dwarf forest." Princess Mumu, who was next to the king, spoke.

"Rest assured, our weapons will not be directed against you, for we have a stronger enemy." Nuan Nuan said with a sigh.

"Who are your enemies? Isn't it amazing? The Dwarven King asked.

Nuan Nuan said: "It's very powerful, you can come out of this forest, and it is estimated that you can also meet our human enemies." ”

Then Nuan Nuan told the story of the invasion of the evil spirits, and she also told the dwarven king that she was hunted by the evil spirits and accidentally came to the dwarf forest.

Nuan Nuan said that the evil spirit was very powerful, and the dwarven king's face changed and changed, and he felt that he was a frog at the bottom of the well, and he did not know anything about the outside world.

Nuan Nuan comforted the dwarven king, as long as they don't leave this dwarven forest, they will be fine. Even if they are discovered by evil spirits, they should not bother them.

The dwarven king was relieved, and when he returned to the palace, he asked his soldiers to extend the patrol.

Nuan Nuan stayed here for nearly ten days, and when she was about to leave, she didn't expect that the evil spirit sent mutant warriors to cut down trees in this forest, and was discovered by the patrolling dwarf soldiers.

"What do you say? A group of strange giants are cutting down our trees from outside this forest? The dwarven king was furious and said loudly.

"Yes, we were flying the plane, and when we were about to reach the edge of the forest, we found that many of the trees were missing and became bare. Then I found out that there were a lot of giants down there, so I immediately came back to report. The dwarven soldier bowed his head and told what he had seen.

Since the small plane was built, the patrolling soldiers have been patrolling in the airplane, and the patrol area has also expanded, and they can basically patrol the dwarf forest in one day.

Nuan Nuan had just said goodbye to the dwarven king, but when she was about to leave, she heard such bad news, and she immediately dismissed the idea of leaving.

"Don't worry, King, I'll meet them." Nuan Nuan said to the king.

"Nuan Nuan girl, then I'm sorry for you, thank you so much." The king now believes in Nuan Nuan and knows that Nuan Nuan has great abilities.
