Chen Chu looked at the map and pointed at it.

"This room Wei and the place occupied by the Yan Ya, that is, the northeast of the Tang Dynasty, do you know what is here?"

"There are large plains, there are black soils, which are very suitable for growing food, and although the winters are long and cold, they also have long summers and autumns that are suitable for crops."

"This place is where Tuyuhun is located, and it is also a natural pasture, although most of the countries in the Western Regions are located in the desert Gobi, but because of the severe sun exposure and the large temperature difference between day and night, it is very suitable for growing fruits."

"Although fresh fruits can't be sent back in time, drying fruits into dried fruits is definitely a great delicacy, which can not only further solve the food problem of my Datang, but also enrich the food structure on the table."

Watching Chen Chu pointing at the map, in fact, Li Er and they were all very strange.

Chen Chu knew very little about the current situation in Datang, but he had a clear understanding of the nearby terrain.

These are all things they don't know, but Chen Chu is like a few treasures.

"These places are too remote, even if I can conquer here, I'm afraid it will be difficult to reclaim and develop."

Yu Shinan sighed, there are many people in the Tang Dynasty, but it is also limited, and the land in the Central Plains alone cannot be used up, not to mention such a vast territory.

Chen Chu smiled slightly, and Yu Shinan suddenly slapped his forehead: "By the way, your potatoes and corn...... Now that they are growing better, the old man can't wait for the harvest! ”

At this time, Chen Chu's confidence in his two-flavored plants was full, and he was no longer worried, after all, the growth had grown, and the fruit could still bear few fruits?

"Population, it's good to grow slowly, the place will be knocked down first, and then the people of the Central Plains will slowly move over."

"I remember conquering such places many times in history, but what is the use of putting some to protect everything, some to treat places? Hundreds of thousands of people want to rule such a big place, dreaming. ”

"In the final analysis, the land that really belongs to Datang must have the people of Datang living there, and this is what counts."

Li Er felt that every time he talked to Chen Chu about these things about expanding the territory, he would be very excited.

Because he will always give himself confidence, the army's healing ability has increased, the population has increased, and the place where the Tang Dynasty has been defeated can still be taken by the Hu barbarians?

After everyone finished talking, they continued to sit back and feast.

Chen Chu replenished the base and the water in the pot, and returned to the problem of bandages.

"With Datang's current ability, bandages, pure water and analgesics cannot be produced, so I can only supply them, but the quantity is limited, if I fight a battle, thousands of people will be killed or injured, and I can't help it."

"So let's take our time, when the time comes, let's kill the dog's day first, I will save these materials for a few months or two years, as long as Datang doesn't suffer heavy casualties, it will always be enough for the wounded soldiers."

"I actually asked Datang to ask for a princess,, I Chen Chu is so good that I don't have this blessing, he is a grassland barbarian, a person who lives like a primitive person, why?"

Originally, what Chen Chu said was serious, but the eldest grandson Wuji, Li Er and others were even nodding, and what Chen Chu said about the past few months and a year or two was very accurate.

Datang is afraid that there will be a conflict with Jieli later, and it will probably be so long.

If Chen Chu has these material supports, it can be said that the winning rate can be greatly increased.

As a result, the conversation changed sharply, and almost choked a few people to death.

But when it comes to the primitive life of Jieli people, they can't refute it, after all, Chen Chu's way of living this little life is here.

The two sides agreed that tomorrow Lao Li's people would come over to get a batch of bandages and pure water first, and they would first be transferred to the northern cloud middle land, and they would be stored first, and then they would wait for Chen Chu to slowly accumulate them.

"Let's discuss this toothbrush, you also use willow branches to brush your teeth, how do you feel about this thing?"

Chen Chu asked.

"How? That's it, that's how my ancestors have used it for generations. Liu Zhenghui spread his hands and said, not knowing what Chen Chu meant by the toothbrush problem.

"Confused." Chen Chu slapped the table, which startled Liu Zhenghui and made him depressed, this kid always likes to slap the table.

Li Er and the others couldn't help laughing, only listening to Chen Chu's explanation.

"There are so many people in Datang, where are there so many willows? Everyone has to fold the willow tree down to brush their teeth, brush once and fold a little, and put it away without finishing the brush, isn't it dirty? ”

"Some of the fibers of this thing are very hard and sharp, and when you poke your gums, it's a stream of blood, doesn't it hurt?"

"People who can't get willow branches don't brush their teeth? Your mouth stinks every day, can you smell it comfortably? ”

Chen Chu asked, and the Li Er and others who asked were inexplicable.

, my Datang hasn't even solved the food problem, you tell me about brushing your teeth.

Big brother, only when you are full of warmth can you think about prostitution. Hopefully, let's wait for the food problem to be solved, and then let's talk about this thing.

"Is this topic a little ahead of its time, I'm Datang, I'm not in a hurry about brushing my teeth."

Li Er smiled bitterly, brushing his teeth with willow branches was still not disgusted anyway, now he has Chen Chu's fragrant toothpaste, and it will only be enjoyment in the future.

"So you don't understand life, ordinary people don't have food and clothing, can't toothbrushes be promoted in the upper echelons of the rich? So a good toothpaste is not too wasteful to apply to the willow tree? Isn't the willow branch that has been thrown away stained with the foam of your saliva and the mucus on your mouth? ”

"Aren't you afraid of infectious diseases?"

Hearing Chen Chu say this, several people also looked at each other in surprise.

Nima, is it that serious, the infectious diseases have been pulled out, it won't be to bluff us.

"We designed a tool to scrub the teeth, replacing the willow fibers with animal manes such as horsetails, so that they are soft and do not hurt the teeth, and they can be used again and again after cleaning."

"The most important thing is that our brushing etiquette will be much more serious and beautiful,, don't you all claim to be reasonable, and everyone who reads books has to read etiquette, why are you so rebellious when it comes to toothbrushes?"

Rebel...... Li Er and the others said that they had surrendered, and the more they said it, the more serious it became.

At first, they didn't know what this thing was designed for, and it could make the daily work of brushing teeth beautiful and enjoyable, so it would definitely support it.

"Okay, tomorrow we will report to Your Majesty and start developing it immediately, by the way, Chen Chu, do you have a sketch of the design, and then give it to the craftsman for reference." Li Eryi made a decision.

Chen Chu took out a piece of paper and drew it casually, drawing the appearance of a toothbrush, and several people suddenly had a score in their hearts.

Chen Chu smiled with satisfaction: "When the design is finished, bring me some of the highest quality materials, the best toothbrush is worthy of my toothpaste, and you will definitely thank me in the future." ”

"Brushing your teeth will also become a pleasure, your mouth will be fragrant all day long, and you will feel much more comfortable talking to people than before."

Everyone smiled kindly, Chen Chu really worked hard to make everyone live a more comfortable life.

If the craftsmen's toothbrush is not developed to his satisfaction, they will not be able to spare the person who will be the prisoner.

"Okay, okay, what should be said has been said, or let's play a game while eating!"

At this time, the eldest grandson Wuji saw the chessboard placed next to Chen Chu, and his heart itched.
