The road back to the city is much faster, but compared to the rush to enter the terrifying forest, there are much fewer people coming out.

The Sky Overlord landed on the ground is very attractive, and the Sky Overlord landed on the ground due to injury is even more eye-catching.

However, these teams with wishful thinking were basically not in contact with the Sky Overlord, and they were almost exhausted.

I really don’t know whether this kind of creature with "civilization" is considered a "high-level creature" or a "low-level creature".

When Dong Chen and his friends left the terrifying forest and entered Linwai Village to rest, they found that in less than ten days, there seemed to be a lot of changes in the outside world.

At least as soon as he arrived in Linwai Village, Dong Chen found that the postman was riding a bicycle to deliver the letter, and not only delivered the letter, but also delivered newspapers part-time.

28 There is a triangular space under the beam of the bicycle. The letters are placed in a pocket inside, and the back frame is a pocket for newspapers on both sides of the frame. It can be said that it is very good at using the space.

There is a place in the village that specializes in sending and receiving letters and receiving newspapers. The postman just needs to put the letters and newspapers here, and then the people in the village will distribute them. The postman just needs to take the letters to be sent away.

Originally, postmen were driving beast carts, and in order to maximize the use of beast carts, they would wait until they had enough to set off.

And because there are not many people sending letters, especially when going to places like the village, it is not easy to get a car, which is a waste of time.

But there is no way, the maintenance cost of the beast car is not low, and it costs a bit too much if you run back and forth one trip.

So sometimes, the sender and the recipient will entrust others to carry it, or even directly bring a message. There are few newspapers and other items, but they are ordered. They often receive all the "day" newspapers of the week on Sundays.

It's very annoying.

But there is nothing we can do. Apart from saying a few words, ordinary people cannot go to the post office opened by the City Lord’s Mansion to curse people. However, the post office actually knows that it is not a good thing to keep doing this, and they also want to make some changes.

Ordinary people have no ability to find trouble, but some people or organizations with a little bit of power will cause trouble for them a lot if they delay their troubles due to time.

It is definitely not possible to just call the door. After all, the post office is opened by the City Lord's Mansion, but a city and some surrounding towns and villages are all in the same living circle. There are only a few places in total, so who can't use anyone.

When certain things are always related, don’t say you won’t give face.

Now, with a bicycle, although it seems that some investment is needed in the early stage, the long-term cost will definitely be saved.

This not only speeds up the circulation of information, but also increases wages to busy postal workers and even provides more jobs.

A series of changes and benefits are brought by a small bicycle.

Feimon was very eye-opening about this kind of dexterous and convenient means of transportation. After all, he did not go to the terrifying forest from Blackstone before, but the terrifying forest directly entered in a town northeast of Blackstone. At that time, the bicycle had just appeared in Blackstone and had not yet been spread.

Now I have been in the terrifying forest for a while now, and after coming out, how can I not be surprised to see such a thing?

Looking at Fei Meng's envious gaze, Dong Chen knew what he was thinking, so he smiled and said, "Why do I give you one?"

"This..." Feimon looked at the postman who was leaving Xiaosha and swallowed, "Is it appropriate? Will it be expensive?"

"And I owe you a lot of money. The expedition you hired saved me, and even caused several injuries and offended the Scythe Expedition..."

Feimon's voice is getting smaller and smaller. If these things are counted one by one, if they are converted into money, it will probably cost 15, 2510, 35...35...

It's too much money!

Traveling everywhere is just a poor trip, but when you really have no money, you stay in the same place to write letters or tell travel (adventure) stories to earn some money, and then move forward to the next goal.

This time I was robbed and just wanted to escape, but I lost my bag with my own bag, big package and tent. If I want to travel, I will definitely have to work.

Now I still owe Dong Chen the money, and I have to pay back the money and save travel expenses. When will I pay it back?

"There is nothing suitable or not. A sheep is driven and a flock of sheep is released. You owe me a life, it's not bad."

Dong Chen waved his hand indifferently, "Anyway, I invented this kind of bicycle, and the patent is in my hands. I also have shares in the bicycle factory. I will give you a small idea."

Then there is nothing to say. It’s just a owed 10,000 yuan, and it’s a owed 15,000 yuan. Feimon accepted the fact that Dong Chen wanted to send his bicycle.

And Dong Chen has already said that he gave it away, so he should... he won't ask for money from himself, right?

However, as a traveler who is good at observing and then runs away when the situation is wrong, just from the few glances he saw the bicycle just now, he discovered the mystery here, and then thought of another unfinished invention of his own.

Looking at Feimon, who was thinking hard and occasionally flapping his hands into wings, Dong Chen immediately knew what he was thinking.

"Are you thinking about your flapping wing aircraft?" Dong Chen asked.

Femon, who tilted his head to think about things, was very surprised, "How do you know?"

Dong Chen did not answer his question, but instead showed a mysterious smile on his face and continued, "I not only know this, but I also know that you plan to change the pattern of waving your wings to your legs, because the strength of your legs is greater than that of your arms and lasts for a long time."

"You are also planning to use the principle of bicycle pedals to drive your wings with chains and then use appropriate gear ratios to make it easier, right?"

Listening to Dong Chen's words, Fei Meng's mouth widened wider and wider.

If you were a little surprised at first, you would be shocked now!

How could Dong Chen know what he was thinking?!

"Mr. Dong Chen, are you... you... this is the invention you have already thought of? A new artificial power source for a flapping wing aircraft?"

After thinking about it, this is the only possibility.

After all, the bicycle was invented by Dong Chen, so he must be the clearest of this transmission method and the use of artificial power sources.

"No," Dong Chen shook his head and said seriously, "I am so honest, how could I force my inventions to be a robbery? So you should do it."

"But you have to hurry up. After all, you are not the only one who is studying the wing aircraft. You can discover the mystery of the power of a bicycle, and others may also discover it."

"By the way, I would like to remind you that the Emperor Capital may be about to have bicycles everywhere."

"This is not possible. I have to write down my inspiration as soon as possible!"

As soon as Dong Chen said this, Feimon immediately became busy. A gust of wind ran into the house and started to write it in his notebook.

After remembering a few words, I remembered it and ran out to thank Dong Chen and said, "Thank you, Mr. Dong Chen, you are the biggest, selfless,... smartest professional title I have ever seen."

"I will definitely work hard to pay back the money."

After saying that, he ran back to the house and became busy.

Seeing him like this, Dong Chen shook his head helplessly. In fact, Dong Chen was not too generous.

With this method, the flapping wing aircraft can indeed fly, or even more advanced. Using structural engineering, it can be combined with the glider.

Let it have two modes: human flapping wings and takeoff or drop gliding and takeoff, then gliding in the air with the help of airflow, and then changing the mode until there is no airflow, flapping the wings and flying with human flapping. This will also allow you to fly in the sky for a relatively long time without fuel or engines.

However, the mode is too complicated, and the strength and efficacy ratio of the fuselage will definitely not work. If you don’t fly fast, you can’t create too much. The future of development is really limited.

Even if the power is replaced with more advanced power, it is the same, it is not as simple and crude as a fixed-wing aircraft.

It is an aircraft without a future, or the future is too far away, so far away that it cannot be seen within hundreds of years.
