Lin Chuan broke a few willow branches and gave one to Cao Cao, Cheng Yu, Xu Chu and Jia Xu.

"This ...... What is it? ”

"Put it in your mouth, bite it open, and brush your teeth with the serrations on it with some salt."

"There's still some mint leaves here, just chew them twice after brushing them."

Lin Chuan said, and put the salt and mint leaves in front of the four of them.

The four of them looked at each other, looking at the things in front of them, and they really didn't quite understand what Lin Chuan meant.

"Young man, this salt is so precious, how can it be so bad?"

Xu Chu couldn't help it and spoke.

In Xu Chu's eyes, salt is something more precious than silver.

Just using it for dispensable things is simply a tyrannical thing.

"Precious?"

"I still have hundreds of catties of salt in my warehouse, precious fart."

"I can use such a little salt to make your mouth not so stinky, I can love you a little higher when I eat, it's worth it more than anything."

With that, Lin Chuan picked up the willow branch and began to brush his teeth.

Seeing this, everyone hurriedly followed suit.

And Cao Cao glanced at Lin Chuan suspiciously, and sighed at his hand:

"Zhongde, Wenhe, do I have bad breath?"

The two just laughed and didn't dare to make a sound.

Anyway, it doesn't stink, but it's a little weird.

If Lin Chuan didn't remind him, everyone hadn't felt it yet, but once Lin Chuan reminded them, several people felt more and more awkward about this strange smell.

Seeing that the two didn't speak, Cao Cao had to silently pick up the willow branch and follow Lin Chuan's example to brush his teeth.

Its practical willow branches and salt to brush his teeth, Lin Chuan also has no way.

In this environment, there is no way to make toothbrush bristles, after all, there is no nylon filament, the raw material of toothbrush bristles.

As a result, Lin Chuan had to follow the example of the willow branches used for brushing his teeth in ancient times.

It's certainly not as effective as a modern toothbrush, but at least it suppresses bad breath.

In addition, Lin Chuan, Cao Cao and others do not smoke, and they rarely eat garlic and other foods with a strong taste.

It's also good to use some mint and salt to get rid of bad breath.

"I'm telling you, don't underestimate brushing your teeth."

"Do you know how many bacteria we have in our mouths?"

"Tartar in the mouth, as well as some food debris, are the culprits of the odor."

"If you don't brush your teeth for a long time, it won't be long before your teeth rot black."

After Lin Chuan rinsed his mouth briefly, he began to educate his mother-in-law with great painstaking efforts.

Everyone really couldn't understand Lin Chuan's "fairy words", so they had to nod thoughtfully.

In fact, Lin Chuan didn't mean anything else.

The main thing is that their mouths are too stinky and affect their appetite.

After a simple brushing of his teeth, Lin Chuan took Cao Cao and the others to have a simple breakfast, and then went for a morning run along the river.

The so-called plan of the day lies in the morning, running in the morning and running at night every day, digesting food, and strengthening the body.

After this period of time, Lin Chuan found that although Xu Chu and others were strong and strong, their physical fitness was still not good, and sometimes they often had backache.

If you don't exercise diligently, you will live a life of eating, sleeping, sleeping and eating on the island every day, and in a few days, Xu Chu's tendon meat will also turn into a lump of fat.

Xu Chu is still like this, not to mention Cao Cao and Cheng Yu Jia Xu.

These three people don't seem to be young, they are already middle-aged and geriatric diseases, and if they don't exercise, they will reduce their lifespan.

When he was jogging in the morning, Xu Chu inadvertently saw the end of the field, and suddenly exclaimed:

"What is this, boy?"

"Why is there such a huge thing in the field?"

Lin Chuan had long been accustomed to the fuss of this group of people, and glanced in the direction Xu Chu was pointing.

It was a huge Ferris wheel-like thing.

"Waterwheel, you haven't seen this yet?"

Lin Chuan wiped the sweat from his forehead and said indifferently.

In fact, it is not uncommon for people who have never seen a watermill.

Nowadays, most people live in the city, and these four people should have just come out of a mental hospital, and it is normal that they have not seen them.

"Water wheels? I've seen watermills, but they're not that big. ”

Xu Chu suddenly became interested and walked in the direction of the waterwheel.

When I helped Lin Chuan farm before, because the crops in the field were too high, I didn't notice such a behemoth at all.

Cheng Yu, Jia Xu and others also followed in the past.

Lin Chuan said as he followed:

"It's for watering crops, and it's very practical."

"There are so many fields, if I water them alone, I won't be exhausted to death."

Lin Chuan looked at the few people who were making a fuss, rubbed his shoulders and said.

Cao Cao and the others widened their eyes and came to the bottom of the waterwheel, only to see how big it was.

In fact, waterwheels have appeared in the Eastern Han Dynasty, but they have not yet been promoted.

What's more, the waterwheel made by Lin Chuan is several times larger than the waterwheel that appeared in the Eastern Han Dynasty.

After the improvement of the water wheel, the efficiency has been greatly improved.

Everyone looked at this huge waterwheel and couldn't help but get excited.

If you have this thing, then what are you worried about?

Get to work, and the efficiency has improved by more than one notch!

"Now that we're all here, let's do some work by the way."

Lin Chuan smiled slyly, turned around and walked towards a small wooden house at the head of the farmland.

In this small wooden house, there are a large number of farming tools.

Such as sickles, plows, shovels, shovels, rakes, and many more.

Most of these are made of pig iron or stone.

On the occasion of the slack farming, Lin Chuan was idle and had nothing to do, and he made a lot of shares, since these four people came, it was enough.

"Immortals, what is this?"

Everyone poked their heads over one after another and looked at the farming tools in Lin Chuan's hand with puzzled expressions.

"Haven't seen a plow? Planing. ”

Lin Chuan said angrily.

This group of people, how do they feel that they have never seen the world at all.

I've never seen anything, I don't know anything.

Even something like ice-making that a child can do is actually enshrined as an immortal art.

Why can't you let yourself pick up a few normal people?

At this time, Lin Chuan no longer expects to have a girl by his side, but whenever there is a normal person, Lin Chuan feels that he is burning incense.

Here came four people, well, four fools.

Helpless to helpless, what should be taught still has to be taught.

Lin Chuan saw and told them how to use the plow and demonstrated it himself.

The use of the plough was not difficult, and everyone learned it after watching it once.

This thing is much more efficient than turning the earth!

Turn the land over and then sprinkle the seeds!

Everyone immediately figured it out, no wonder Lin Chuan could still plant so much land on the island alone.

All-in-one plug-in!

After learning it, several people rushed to pull the plow and experience the joy of farming.

Lin Chuan and Cao Cao stood aside, watching the work of several people.

At this time, Lin Chuan suddenly felt.

A few more people around, even if it's a fool, doesn't seem to be bad.

At least I can do my job.
