When Ye Jinyu heard that the sun was soaring, he didn't know what the situation was, but now he ran out with these old men to take a look, only to find that the situation was wrong.

"It's broken, it's broken! This Li Chunfeng didn't listen to my advice, this is a bad thing. Ye Jinyu slapped the white marble railing hard, but accidentally used too much force, and his hand hurt.

The emperor was envious of the immortals beside Ye Jinyu, and when he heard the gods talking to himself, he couldn't help but ask curiously: "King Shenxiao, could it be that this immortal who soars in the daytime is an old friend of King Shenxiao?" The words are full of inexplicable anticipation.

"What old friends? It's Li Chunfeng! Ye Jinyu explained angrily: "We designed a board that can fly, but it is not finished yet; I told him not to try it yet, but he didn't listen, and now it's okay, and the people fly up. ”

The emperor was even more incredible: "It turns out that the flying artifact was actually made by a god man. He also said: "Why can't people fly to the sky, is it because the gods in the sky don't allow it?" ”

Ye Jinyu stared at the flyboard in the sky and said, "You can go to the sky, no one says no; It's just that the design of that flyboard is not perfect, and it can go up and down; When he flies up, I'll see how he gets down......"

The Emperor also stared at the flyboard and muttered, "In this way, this flyboard will fly all the way to the nine skies." ”

Ye Jinyu didn't know if it was outside the clouds, but he knew that if he rose like this, if he fell down, he would have to fall into a meat patty. I just hope that the power in the battery is almost consumed, and when the power is exhausted early, don't fly too high.

……

Ye Jinyu left, Li Chunfeng sat on the door panel and felt a little bored, and didn't want to come down.

After sitting for a few more minutes, I thought I could try and find out what problems could be solved before the God-man returned.

So he handed over the pliers and other things placed on the door panel to Xiao Daotong, and said, "You and put away the tools of Ye Shenren, this object is very exquisite, and it cannot be lost." Poor Dao will try it first. ”

Then I flipped the switch.

Under the impetus of the electric current, the suspended float actually really had an effect, floating up with the door panel and the upper one, and the speed was not slow, and soon exceeded the roof.

"Hey! It's really flying. ”

Seeing that it was flying a little high, Li Chunfeng wanted to turn off the switch and let the door panel fall again; But the yearning for the sky made him can't help but think: Do you want to try to fly higher again?

As long as he doesn't move the switch, the charm will always work, sending him into the sky at a uniform speed.

Seeing that the door panel could not go up or down, the little Taoist boy below was stunned, and shouted loudly: "Come on, Li Daochang has ascended to heaven!" As soon as this little Taoist boy shouted, he alarmed the rest of the National Teacher's Mansion, and sure enough, he found that there was something in the sky carrying a person flying in the sky, looking at the shadow, it was really Li Chunfeng; This caused another exclamation, which spread all the way to the streets outside, where many people were running to celebrate the Turkic victory; At this time, Li Daochang's ascension was seen by them, so Chang'an City was boiling, the prince over there had just won a big victory, and there were people here who were soaring in the imperial capital during the day, and there was a Ye Shenren living in the city for many years; What does this mean? This shows that Chang'an is a place blessed by God, and God bless the Tang Dynasty!

There were cheers everywhere, and many fools and fools even knelt on the ground and kowtowed.

The reaction of the people on the ground, Li Chunfeng could not see, the board became higher and higher, rising from thirty meters to fifty meters, and then to one hundred meters.

Wow, looking at Chang'an City from the sky, it turns out to be like this, this city is like a chessboard, the streets are horizontal and vertical, and people are in it, like chess pieces.

Continuing to rise, Li Daochang got taller and taller, and saw that the sky was getting closer and closer, and the houses on the ground and the streets were getting smaller and smaller. Li Chunfeng wanted to stop, but he was a little looking forward to what it would be like to be above the nine heavens; Will there be a heavenly palace?

Now that you've come up, why don't you go up a little bit and take a look? Keep giving yourself a reason to go up.

When he reached 300 meters, he was in trouble, and when he was in the troposphere, the temperature dropped by about 0.6 degrees Celsius for every 100 meters he ascended; the temperature was already low in this winter; when he rose to 300 meters, the temperature had dropped by about two degrees; in addition, the higher the wind, the stronger the wind, and when the wind blew, it was cold. What's more troublesome is that the design of this flying door itself is very unreasonable, only the four corners are pasted with symbols, and there is no hanging counterweight below. When Li Chunfeng sits in the middle, there is no problem with the load bearing and stress of the door panel; However, when the center of gravity is a little offset or subjected to external forces, the flyboard is easy to flip; This is not now blown by the wind, and the door panel is a little unstable. Li Chunfeng could only sit in the middle as upright as possible, like a god statue, and did not dare to move.

At this point, Li Chunfeng, who originally wanted to rise into the clouds to take a look, was a little embarrassed, and couldn't help but retreat in his heart.

Forget it, let's go to the clouds next time I get a spaceship; It's better to go back to the ground first.

As for the question of how to fly so high, Li Chunfeng had already thought about it; Just turn off the switch of the godman, and the door panel will naturally carry him down when it loses its upward force; When it was almost there, he turned on the switch again to make the charm buoyant, and so on, only a few times to descend to a safe height; Just jump off the door panel.

It's a pity that he doesn't know much about fluid mechanics and aerodynamics; I didn't even know that the Earth was round, and that there was an atmosphere outside the sphere. He only thought that the rise was like this, and the fall should be like this, he thought so and did so; I flipped the switch.

The door panel instantly lost its upward momentum and, under the action of gravity, stopped rising. It even began to slowly fall down. Li Chunfeng was very happy, but he didn't expect it to really work; But after only three seconds, under the effect of air resistance, the door panel began to rotate and tilt, looking for a corner with the least resistance and falling down; Which side of the door panel has the least resistance behind it? Anyone with a little physical knowledge knows that it is the side with the smallest force area, and the side of the door has the smallest force area? The top and bottom, of course.

In an instant, before Li Chunfeng could react, the door panel leaned sideways and fell straight down with Li Chunfeng, and he only had time to hold the black box-shaped dantian. Seeing that something could not be done, Li Chunfeng hurriedly turned on the switch at the dantian of the box again, wanting to borrow the talisman to float up; The talisman worked again, and the door panel flew up instantly, but the wires connected to the battery couldn't lift such a big person as Li Chunfeng, and it collapsed directly from the door panel with a little force, tearing off half of the talisman paper and floating in the sky. As soon as the wires were broken, the door panel lost power again and fell down. At this time, Li Chunfeng was already far away from the door. Struggling, the height plummeted to two hundred meters.

The people on the ground watched the immortals soar in the daytime, and suddenly saw the immortals actually falling from the air, and they all let out exclamations, and the sound even reached Li Chunfeng's ears.

Li Yuan, who was holding on to the white jade railing, was also nervous, why didn't Daochang Li soar to the Nine Heavens, and fell down halfway.

Ye Jinyu even closed his eyes, unable to bear to see Li Chunfeng turn into a meatloaf.
