…………

And in the valley, I don't know how they died.

It was because of Qiao Kang's arrival at the research institute that he saw the dwarf Yili from a distance, directing Ward to test the steam car.

How to kill that steam maple?

He simply waited in the woods outside the valley. He is still a scooter type, but the front wheel has been changed from the previous fixed to steerable, which is a bit similar to the hand on the other side of the earth. Liu Feng is watching the steam with Mina. Progress of the car.

not yet in

".'Sir." The dwarf Yili turned his head to see Liu Feng, and hurriedly stopped what he was doing.

The car has obviously been improved. This time the material of the four wheels has been changed to a new alloy. Has there been a breakthrough in the car? "Liu Feng had a faint smile on his face.

"The problems that the adults mentioned last time have been changed to the tractor.

At the front of the car is a small steam engine. Kindly touched his head.

"You guys continue, I'll take a look." Liu Feng walked to the side and let Ward, who was next to him, immediately gave a military salute.

"How is it, both of them are a little nervous. This is an experiment in front of the Lord City Lord after the improvement. As for whether it can be successful, I don't have a good heart. I'm experimenting now, and I originally planned to inform the adults when the experiment was successful." Get up, boil the water, produce a lot of water vapor, and soon the steam engine is started.

"Yes." Yili nodded and motioned for Ward to continue.

a lot.

This is not the first time the two have cooperated, and they operate the joystick in front of them in a very tacit understanding.

"Buzzing..."

The two rockers of the fuel burner in the steam engine control the direction of travel of the steam car.

Mina's eyes widened. Come on, although the car vibrated a lot this time, it was obviously faster than the first-generation steam car, one-third faster than last time.

Ward turned the joystick in his hand and the car started to move forward slowly as Yakiri moved the joystick.

Ward holds the control car"

When approaching Liu Feng, Yili turned another joystick, and the car would be amazed every time he saw it, even though this was the second time he saw a steam car.

Steam this time. . . . . . tie.

"Second shift, ( ̄▽ ̄). Please support." The front of the car turned to the side, successfully completed a turn, and drove back.

"Buzz... Slowly stopped in front of Liu Feng.

. . . .

Eight hundred and sixtieth chapters: Leia is back. (3 for support)

"Sir, this is an improved steam car." Yili and Ward got out of the car, feeling a little uneasy in their hearts, wondering if they could satisfy the adults this time.

"Very good, much better than the last time." Liu Feng nodded, looking at the steam car he had looked at, it didn't feel like the first time it would fall apart at any time.

"Add a shell to the body, similar to the carriage of a carriage." Liu Feng looked at the body of the steam car, there was still one carriage left.

"Yes," said Yili respectfully, picking up a notepad and writing.

"There are still some small problems to be improved, such as here..." Liu Feng made a few suggestions, all of which are relatively serious problems with steam cars at present. After the improvement, this different and improved car has been initially completed.

"Okay." Yili replied, writing quickly, and at the same time there was a new idea in his mind.

"The only problem is the wheels. Niu San should have arrived at Lord Nagahu by now. The rubber will be shipped back soon, and the wheels will be covered with rubber at that time, and the driving will be more stable." Liu Feng patted it. The new alloy wheel in front of him had a faint smile on his face.

"It should have arrived a few days ago, the imaginary version of the steam is on the way." Mina counted the time and responded.

"Let's go." Liu Feng nodded and left without disturbing Yi 560 Li's research.

"Tatata...the city is over, I must go out of the valley.

After leaving the valley, surrounded by the Wolf Warriors team, the carriage quickly drove towards Xiyang City.

Qiao Kang hid in the woods and watched the carriage drive by in front of him, but the letter he had no choice but to write already wanted Liu Feng's head, but it didn't mean he wanted to die. Just one.

"A noble who is greedy for life and fears death." Qiao Kang was very annoyed, watching the carriage go away, and then got on the carriage from the tree. As he walked into the city, he muttered, "It seems that we need to find other opportunities. "

"Ta Tata..."

"There...hahahaha..."

Qiao Kang will soon have.

He couldn't help laughing at the thought of his plan.

......

"Huhuhu......"

Leia and Sarina's group were coming out of the confinement forest at this time.

Beside them are six huge hot air balloons, led by them (bafa) towards Xiyang City.

"Everyone, pay attention, be careful not to collide." Leia flapped her wings and told her companions to pay attention, and it was a coup, it was the hot air balloon with a wooden box.

"Yes." Sarina and the others responded in unison, pulling the rope tied to the hot air balloon and not daring to loosen it.

The rope in Leia's hand was flying in the air above the veins, and in her, she was so absorbed that she did not dare to let go.

"Roar......"

In the hot air balloon marked with the number '3', a weak roar can be heard from time to time. Everyone has been accustomed to this. Be careful of the collision of the hot air balloon, especially weak, and finally persisted here.

"You should be able to get to Xiyang City before the sun sets." Leia took out her watch from her arms, looked at the time, and shouted loudly.

"Yes." What everyone said again was that the hot air balloon with the wooden box was bright.

"Whoosh..."

More than three hours later, the air force base outside Xiyang City appeared in the eyes of everyone.

On the air base, a figure was used to moving towards Lei, and the roar was getting weaker and weaker these days! Big sister, it's Frey, she can fly. ' Sarina exclaimed, with a smile on her face.

"Yeah." Leia nodded, looking at the figure that was getting closer and closer, her cold face softened and Xu Du responded in unison, her tired eyes had a big sister..." Frey flew to Lei. Next to Ya, she looked at her carefully and secretly breathed a sigh of relief when she found that she was not injured.

"Have Frey's wings grown?" Leiya and the others approached quickly.

"." Frey said lightly.

"Great, Miss Frey can fly." The rest of the bird orcs were very happy.
