“In theory, it’s possible, but it’s difficult to popularize it.”

Seeing Li Lizhi's expectant face, Zhou Yu immediately tapped the iron water pressure well with his fingers and expressed his judgment.

As far as Zhou Yu knows, pressurized wells first appeared in the Song Dynasty.

It was not until the 1970s and 1980s, when domestic steel production began to surge, that it gradually became popular in rural areas.

Compared with the Tang Dynasty, the production and manufacturing technology of the Song Dynasty did not make obvious progress.

Therefore, as long as the principle was understood, it was not impossible to build a water pressure well in the Tang Dynasty.

However, during the Zhenguan period of the Tang Dynasty, even iron pots were not fully popularized.

It is easy to imagine how difficult it is to promote pressurized water wells.

"Gurgle."

Seeing Li Lizhi's disappointed look, Zhou Yu said nothing more. He picked up a clean tomato and took a bite.

Then, the fragrance, sourness and sweetness of the tomato bloomed on the tip of the tongue.

"Slurp."

Squeeze hard with your fingers and suck hard with your big mouth.

The sour and sweet juice all flowed into the throat.

In just a moment, Zhou Yu narrowed his eyes.

Naturally ripened tomatoes are simply more delicious than those sold in supermarkets.

"Little Neng-jun, I want seven too, I want seven too~"

Seeing Zhou Yu eat the tomato in just a few bites, the little kid who was having fun immediately came over while swallowing his saliva.

"You little greedy cat."

Zhou Yu scratched the little girl's nose lovingly, then handed the biggest and reddest one directly to her.

The little person was holding a big tomato, just like a greedy hamster.

Zhou Yu's heart was instantly melted by cuteness.

"Come, Chengyang, this big one is for you to eat."

In order to double his happiness, Zhou Yu happily continued to feed the animals.

"Thank you, Brother Zhou Yu."

Princess Chengyang took the tomato and her big eyes were filled with joy.

Compared to the little girl's bold and aggressive eating, her movements when eating tomatoes are much more ladylike.

The little silver tooth gently bit the tomato, then sucked it hard like Zhou Yu.

Only after all the sour and sweet juice entered my mouth did I start to eat the flesh in small bites.

"How is it? Are the tomatoes delicious?"

Seeing the two little ones eating with gusto, Zhou Yu's face was full of satisfaction like an old father.

"Good, good, sour and sweet, I'm a tomato."

The little milk ball with tomato juice all over its face was the first to express its opinion.

After saying that, she didn't forget to stick out her tongue and lick the corner of her mouth.

As for Princess Chengyang, she nodded shyly.

However, from the smile between her eyebrows, it can be seen that she also likes tomatoes very much.

"Master, can this be grown in the Tang Dynasty?"

Just when the two little ones were eating with gusto, Li Lizhi, who originally had a disappointed look on her face, came over with tomatoes.

Zhou Yu felt helpless when he heard this.

Although I know that this girl must have come with a mission from Li Er.

But seeing her looking so worried about the country and the people still makes people feel very uncomfortable.

He is obviously just a child of twelve or thirteen years old. If he were in modern times, he would be at the age of innocence.

But the Li Lizhi in front of him seemed to be carrying a heavy shackle, and did not have the liveliness that a child of this age should have.

Especially when comparing her with the little milk ball, Zhou Yu felt an inexplicable sadness.

In Zhou Yu's opinion, childhood should be like that of the little Sizi, crying when necessary, laughing when necessary, eating and drinking to one's heart's content, and playing to one's heart's content.

As for how to lead the Tang Dynasty to prosperity, that is something Li Ercai should consider.

This was Li Er's fate after the Xuanwu Gate Incident, and it should not be borne by a child who was only twelve or thirteen years old.

Especially when Zhou Yu thought that the naturally beautiful little girl in front of him had only ten years to live.

I felt irritated for no reason.

"Master, it is my honor to be so presumptuous."

Seeing Zhou Yu frowning and remaining silent.

Li Lizhi, who was originally full of anticipation, suddenly lowered her head with a nervous expression.

Seeing this, Zhou Yu couldn't help but ask helplessly, "What year of Zhenguan is it in the Tang Dynasty now?"

How many years was Zhenguan?

Doesn’t the immortal know what year it is today?

Hearing Zhou Yu's question, Li Lizhi, who had originally lowered her head, couldn't help but feel confused.

However, after seeing Zhou Yu's frown, she still answered honestly: "It is now the sixth year of Zhenguan in the Tang Dynasty."

"It turns out it's already the sixth year of Zhenguan."

Zhou Yu was shocked when he heard this, "So you're going to marry Chang Sun Chong next year?"

Um?

Seeing Zhou Yu asking this, Li Lizhi couldn't help but be stunned.

But then, he lowered his head shyly.

What does it mean when the immortal asks about his wedding date?

Doesn't he want to marry his cousin himself?

But this marriage was decided by Aye a long time ago.

Now that the entire Chang'an City knows about it, what reason can I find to cancel the engagement?

…

Just as Li Lizhi's mind was full of wild thoughts, Zhou Yu said in a serious tone, "Go back and tell your father that if you don't want your son to die young, cancel your marriage with Chang Sun Chong. As for the reason, you only need to investigate the offspring of those who married within three generations of their maternal relatives in Chang'an."

After Zhou Yu finished speaking, he was too lazy to explain further.

He was afraid that if he continued talking, he would not be able to help but tell Li Lizhi the truth.

He was not willing to do such a thing.

After all, most people in this world do not have the courage to face death.
