Tang Dynasty: Consort Wu? Your Majesty, please address her as the Crown Prince's Consort.

Just as Li Chengqian and Li Tai were bickering, Li Shimin and Li Yuan slowly approached from not far away.

Upon seeing this, everyone quickly stepped forward to pay their respects.

"Your subject greets Your Majesty and Your Majesty!"

Looking at the group of grandchildren in front of him, Li Yuan finally showed a kind smile.

"Hehe! No need for formalities, this is a family dinner, we don't do that!"

Upon hearing this, Li Chengqian chuckled and said:

"Grandpa! I brought this wine myself, including several new varieties. We're sure to drink plenty!"

As soon as Li Chengqian finished speaking, Li Yuan became interested.

"Oh? Then you definitely have to try it!"

Li Tai, who was standing to the side, curled his lip in disdain upon hearing their conversation.

It's just wine, isn't it? What kind of fine wine hasn't Grandpa Emperor tasted? Stop showing off!

In the blink of an eye, night fell.

One delicious dish after another was served on the table.

Li Chengqian immediately gave a look to the eunuch beside him, who immediately understood.

Soon, bottles of wine were distributed to everyone's table.

Everyone was dumbfounded when they saw the wine in front of them.

Li Shimin immediately spoke with exasperation:

"You unfilial son! You actually used a glass bottle to store wine?"

Not only Li Shimin, but even Li Yuan and Empress Zhangsun, who had always sided with Li Chengqian, couldn't help but speak up this time:

"Brilliant! Using a glass bottle to hold wine is indeed a bit too extravagant!"

Hearing their words, Li Chengqian couldn't help but smile slightly and said:

"What if I had the method for making glass?"

"really?"

Upon hearing this, Li Shimin immediately became restless.

He didn't think this rebellious son was joking. The movable type printing and new papermaking techniques he had previously obtained from this son had already been verified.

The cost of a book was reduced to a dozen or so coins. With such a low cost, as long as he increased the scale, all the people of the Tang Dynasty could afford to buy books.

Now this rebellious son claims to have the method for making glass. Glass is something else entirely; if we could really get the method, we'd be rich!

Seeing everyone looking at him expectantly, Li Chengqian spoke nonchalantly:

"Of course, the raw material for this glass is just sand, which can be found everywhere. If you want it, Father, I'll give it to you!"

Upon hearing this, Li Shimin immediately burst into laughter.

"Hahaha! Excellent! He truly is my good son!"

Upon hearing Li Shimin's praise, Li Chengqian couldn't help but roll his eyes at him.

Ugh! You scumbag dad!

When things are going well, he's a good son; when things are going well, he's a rebellious son!

……

Li Tai, who was standing to the side, couldn't help but frown as he looked at Li Chengqian.

"Li Chengqian, do you really have the method for making glass?"

Snapped!

As soon as Li Tai finished speaking, Li Chengqian slapped him on the back of the head.

"Who are you talking to? Call me 'Big Brother'!!"

"You... Li Chengqian, don't go too far! I'm just asking a question!"

Snapped!

"Still calling me that? Call me Big Brother!"

Seeing that Li Chengqian still wanted to fight, Li Tai couldn't help but subconsciously shrink his head back.

"Big...Big Brother!"

"Hey! This is my good younger brother. I do have the method for making glass. I will give the recipe to the old man when the time comes."

However, this stuff is only profitable when it first comes out; once more glass enters the market, it loses its value.

Upon hearing this, Li Tai couldn't help but nod.

He wasn't stupid; he naturally understood what Li Chengqian meant.

When Li Yuan had the cork removed, dark red wine flowed from the glass bottle.

A unique aroma of wine wafted through the air.

He couldn't help but look at Li Chengqian with some surprise and said:

"This is... wine?"

Upon hearing Li Yuan's words, Li Chengqian couldn't help but smile and nod.

Wine existed in the Tang Dynasty. After Zhang Qian introduced grapes to the Han Dynasty, people soon began to try making fruit wine from grapes.

By the Tang Dynasty, wine had become one of the most common fruit wines.

However, wines during the Tang Dynasty were sweet, while Li Chengqian's wine was an 1982 Lafite that cost one point per bottle in the system's store!

Although this wine became very famous in later generations, Li Chengqian thought it was just so-so.

This stuff only tastes slightly better with Sprite added, since Li Chengqian himself wasn't a big drinker.

"Your Majesty, please try this wine. The brewing method is different from the wines currently available in the Tang Dynasty, and the flavor is also different."

Upon hearing Li Chengqian's words, Li Yuan picked up his wine cup and took a sip.

As he swallowed the wine, Li Yuan couldn't help but frown.

"This wine isn't sweet; it's actually a bit sour and astringent. Not only that, it has a oak barrel flavor. Could it have been aged in oak barrels?"

Upon hearing this, Li Chengqian couldn't help but show a look of surprise.

Holy crap? My own imperial grandfather is amazing! He's a drunkard, yet he can still tell the difference?

Li Chengqian smiled and nodded, then said:

"As expected of my grandfather, this wine has indeed been stored in wooden barrels for many years."

Upon hearing this, Li Shimin, who was standing to the side, couldn't help but take a sip, and then couldn't help but reveal a pained expression.

"What kind of rubbish is this? It's sour and astringent, not sweet at all, and not even as good as my imperial wine!"

Upon hearing this, Li Chengqian, unusually, did not refute it.

All I can say is that this drink is impossible without Sprite!

Of course, drinking Sprite directly is actually better!

Everyone seemed uninterested in the wine that Li Chengqian brought out, but Li Chengqian didn't think much of it; it was just as expected.

Soon, a eunuch came in carrying several buckets filled with ice, and the buckets were also filled with dark green wine bottles.

Seeing this, Li Chengqian quickly called out to everyone.

"Come on! Try this, wheat juice, it tastes even better chilled!"

呲!

Li Chengqian picked up a bottle and pried it open with his chopsticks, producing a soft soda-like sound.

After taking a bite, Li Chengqian couldn't help but let out a comfortable sound.

"Ah~ That's great~ This wine is so delicious!"

Seeing this, everyone followed suit and started drinking wheat juice.

Feeling the cool and refreshing sensation of the wheat juice, everyone couldn't help but marvel.

"Hey! This wine is great, ice-cold and refreshing, and it cuts through the greasiness!"

Li Shimin was seen enjoying a bite of mutton and a sip of beer with great relish.

"I have to say, this drink is absolutely perfect with grilled meat!"

Upon seeing this, Li Chengqian couldn't help but smile slightly.

He wasn't surprised by the result; this was wheat juice, after all, which was loved by people all over the country even in his previous life.

Spicy crayfish, street-side barbecue, and a bottle of chilled wheat juice.

This life couldn't be better!

On New Year's Eve, every household is lit up.

As the capital of the Tang Dynasty, Chang'an was brightly lit tonight, and even at curfew, Zhuque Street was still bustling with people.
