Compared with the natural rubber produced by the King of Rubber, the soaphorn produced by the King of Soaphorn is a little shabby, and even just looking at the output, compared with other natural wonders, the King of Soaphorn does not deserve to be a natural wonder at all.

However, Ning Yuan was still very surprised by the appearance of this soaphorn king, because he was fed up with the days of wearing oily twist clothes all day long.

Because of the meat and training every day, it is inevitable that the clothes will be stained with some oil, sweat and blood.

In ancient times, when there was no laundry detergent and laundry detergent, it was not easy to wash away these stains.

Ning Yuan once took the initiative to study the methods of washing clothes in the ancients, and then learned about several ancient natural detergent recipes.

These ancient recipes are rice water, soap horn, bath beans and plant ash.

Rice washing water and plant ash are more or less, but their decontamination ability is really limited, and some stubborn stains are difficult to remove with them.

Bath beans are made by grinding beans and were used by the ancients for bathing and washing their hands.

In the Condor Territory, soybeans are an important food resource, because they have not yet formed a primitive accumulation, so people usually can't eat it if they want to, let alone take a bath with it.

The people take food as the sky, and this kind of waste of food is absolutely impossible for Ning Yuan to do.

Saponaria powder is a very good natural detergent, but unfortunately in the territory of the Condor Territory, there doesn't seem to be this kind of plant, so Ning Yuan has been wearing clothes with various stains in the past few years.

Although the Saponaria King is not as good as other natural wonders, it came at the right time.

With soap powder and soap made from soap seeds, it is believed that the hygiene of the Condor Collar will be greatly improved.

Although Ning Yuan's adaptability is very strong, he is a modern person after all, and he will have some cleanliness habits more or less, so this soaphorn king is like a timely rain, and it comes at the right time.

In addition to these natural wonders, Ning Yuan also found some very interesting things in Jun Moxie's mansion.

The first interesting thing is a couple of ancient versions of bicycles.

They are called ancient bikes simply because they are bulky compared to modern ones.

Modern bicycles generally weigh twenty or thirty pounds, which is very convenient to carry. However, the bicycle in Jun Moxie's Mansion weighed more than fifty pounds, and it looked big and stupid.

Ning Yuan knocked on the car body with his hand and found that the entire frame was welded with solid iron pipes, no wonder it was so heavy.

The entire bike is welded with iron pipes of varying thicknesses, even the bars.

I don't know if it's because the technology is not up to par, the crankset of this bike is very large, and then the matching chain and chain links are also very huge.

Ning Yuan carefully observed for a while and found that the wheels and strips should have been cast directly, and they were cast together.

The wheels are very wide, and there is a layer of rubber directly wrapped on them, and he pinched them with his fingers, feeling that the elasticity is not very sufficient, and it seems that there should be no inner tube inside.

After observing, Ning Yuan simply tried to ride directly in the courtyard.

Well..., except for the fact that it takes a bit of effort to pedal at the beginning, once the speed is up, it is still very light.

This bike has no front brake, only a rear brake, you need to step on it, and as soon as you step down, it stops immediately, and the braking ability is still very good.

"Come on, give me all these bicycles to take proper care of, and when I get back, give them to the craftsmen of the research institute to see if they have any way to improve them."

Although it is a bit cumbersome, Ning Yuan still attaches great importance to this new thing, and it just so happens that there are many halfling craftsmen in the research institute that has just been established, and they have just finished improving the mobile mechanism of the siege tower, and I believe that a bicycle should not be difficult for them.

Although the bicycle is not as fast as the war horse, the war horse is a living thing, it is a dead thing, and the war horse needs to rest and eat, but it does not need it, so the two can be said to have their own strengths.

Although the bicycle could not be used as a mount for cavalry, it was still good for some infantry to rush on.

By the time the era of StarCraft arrives, the mode of war will change completely.

When the time comes, the march and battle will not be like now, and it will be teleported with a "whoosh".

All soldiers have to rely on their feet to get on the road, so the appearance of bicycles still has a certain strategic significance.

Although it is much faster to travel by bicycle than on foot, it is not without its drawbacks.

The first is that the cost is too high.

Now the steel in everyone's hands is not enough to build weapons and equipment, where is the surplus to distribute to bicycles, so if you can't reduce the weight of bicycles, then you can't mass-produce.

Although Ning Yuan had snatched a large iron mine, with the increasing number of his troops, the steel resources in the territory were also a little tight, so he hoped that the craftsmen of the research institute could improve it, and it was best to replace the solid iron pipe with a hollow steel pipe.

The second is that bicycles are more demanding on the environment.

On smooth roads, riding a bicycle is much faster than walking, but if you want to be in the wilderness, the ground is uneven, and the bicycle is impassable, so there is another big premise for production bicycles, that is, to build enough roads.

Otherwise, there are only bicycles and no roads, and the production will not be of much use.

The second interesting thing is a couple of pieces of papyrus.

Ning Yuan saw a stack of papyrus in Jun Moxie's room, which was full of drawings of parts of various bicycles, and it seemed that these ancient versions of bicycles were designed in this way.

Although the surface of these straw papers is a little rough and the color is a little yellow, the texture is very soft and the toughness is also very good.

As we all know, one of the biggest functions of paper is to carry words and record some important things. Paper has been able to develop so far.

Although Ning Yuan's Condor Leader already had writing, the main thing used to record the text was the parchment scroll.

Using parchment rolls to record text is not only a waste of resources, but it is also not easy to preserve, which is different with paper.

Not only is paper lighter, but it is also easier to preserve, and if it is stored properly, a piece of paper can even be stored permanently.

Of course, this kind of paper is modern paper, and it may not be so easy to develop this kind of paper in ancient times.

In addition to being able to record words, paper is also a necessity in people's daily life, especially toilet paper, which people need to use every day.

In ancient times, because there was no toilet paper, there were various ways to solve the problem of hygiene after convenience, such as leaves, grass stems, and sticks.

Ning Yuan can tolerate poor food and clothing, but he has a habit of cleanliness in terms of hygiene, so every time he is convenient, he will go to take a bath, whether it is winter or summer, rain or shine.

Although his physique in the game is better, taking a cold shower in the winter will not be a pleasure.

So when he saw the paper, the first thing that came to his mind was toilet paper.

Ning Yuan believed that the paper must have been invented by Jun Moxie, but it was definitely not made by him alone, so there should be a mature papermaker here, so he immediately sent someone to look for it.

Soon, the papermaker was found.

After finding these craftsmen, the first task given to them by Ning Yuan was to develop toilet paper, and promised to provide them with certain technical support and comprehensive logistics support.

The so-called technical support is nothing more than checking the relevant data on the Internet after getting out of the game, and then memorizing it by rote, and then relaying it to those papermakers after entering the game.

As for when the papermakers will be able to develop real toilet paper, it is not up to Ning Yuan to control, anyway, it has been persisting for several years, and it is not a big deal to wait for a while.
