"Huh? No, no, no, this is for the Emperor, the Emperor, and all the adults to eat. Zhang Nan said with a smile.

"Oh? What is so delicately made is actually eating? This is interesting, take some of it, so that the old man can see it more clearly. Li Yuan urged.

Soon, the large cake was pushed by the waiter to the center of the hall.

"Qingquan, what is this food made of? So snow-white? Are you eating out of snow? Li Er looked at the big snow-white cake and asked strangely. After all, this is the first time Comrade Li Er has seen a cake, and it is also the first time he has seen such white food.

"If you go back to the emperor, this thing is not snow, the name is cream." Zhang Nan said, just gave the waiter a look, and the waiter immediately understood, and then picked up the knife and began to divide the cake, while cutting, the waiter served it to everyone present.

Of course, when the waiter went down for the first time, everyone's faces showed regret, as if they had seen a perfect work of art destroyed.

After a piece of cake was placed in front of everyone, Zhang Nan continued to explain.

"Qingquan, what is this cream made of?" Li Yuan said, and used his chopsticks to pick up a piece of cream and put it in his mouth.

"It's so delicious?! Melt in my mouth, I've never eaten anything so delicious. Li Yuan said with a shocked face, obviously Li Yuan, who likes sweets, this cake is in line with Li Yuan's taste.

Hearing what Li Yuan said, Comrade Li Er was also curious, picked up a chopstick, put it in his mouth, and tasted it.

Unexpectedly, as soon as he entered, Comrade Li Er's eyes widened.

"If it's really melt-in-the-mouth, it's really delicious, everyone, Aiqing, move the chopsticks quickly, don't miss this delicacy." Li Er said, and then took another chopstick cake and ate the fruit attached to it.

"Qingquan, what exactly is this cream made of? Could it be that it has something to do with milk? Li Er asked while eating.

"If you go back to the emperor, yes, this cream is made of milk." Zhang Nan said.

"Milk? Can you drink cow's milk? Li Er obviously didn't expect that this thing was actually made of milk, because the Tang people drank goat's milk, and milk was obviously not in the Tang people's food list.

After all, according to records, the first dairy cows that appeared in China were introduced and crossed by early European missionaries and colonists in Southeast Asia more than 400 years ago and then entered the Yunnan border.

The first cattle ranch was established in 1644 in Xihua Mountain, Beijing, the year the Ming Dynasty fell. In the late Qing Dynasty, with the arrival of colonists, cows also landed in China.

It can be said that before the appearance of these things, milk was only eaten by barbarians, and Sima Qian's "Historical Records: The Biography of the Huns" has such a record: "The customs of the Huns, people eat animal meat, drink their juice and coat their skin; Animals eat grass and drink water, and they can be transferred at any time. ”

Of course, whether it is milk or cow blood recorded in this is still controversial, but it is certain that milk is definitely not in Comrade Li Er's menu.

Of course, as a big foodie, as long as it is delicious and can be eaten, it must be acceptable, so when he heard that it was made of milk, Li Er didn't think much about it, after all, this thing is so delicious, milk is milk, anyway, it's just milk.

"This thing is good, it suits my taste, I will also order someone to get this cow's milk when I go back, Qingquan, you remember to bring me the recipe for making milk, and I will order someone to do it." Li Yuan instructed while eating, obviously this sweet cream had made Li Yuan, an old man who was old and had a relatively light taste in his mouth, like it very much.

"Emperor Taishang, even if the minister gives you this recipe, you can't make it." Zhang Nan said with a smile.

"Oh? Why is that? Li Yuan looked strange.

"Because this milk is not the milk of our old cattle in the Tang Dynasty, but a black and white cow, the name of this cow is called Cow, this kind of cow cannot plow the field, nor can it eat meat, the only thing that can be taken on the body is milk." Zhang Nan said.

"There is such a strange cow in the world that it can't plow the fields? If you can't plow the field, is it still called a cow? Li Yuan wondered.

"That clear spring, where is the cow in your mouth? Didn't I have Datang? Li Er asked.

"If you go back to the emperor, there is really no such thing, and this cow is estimated to be only available in the Netherlands now." Zhang Nan said.

"Holland? Where is the Netherlands? Why haven't I seen it on the globe you gave me? Li Er asked curiously.

"This ...... Your Majesty, you want to ask the minister where this Holland is, but the minister really can't answer for a while. Zhang Nan is also quite helpless, although Zhang Nan has a head of knowledge of the future, but there is one thing that Zhang Nan is particularly good at, that is, geography.

Zhang Nan is an out-and-out road idiot, and in later generations, Zhang Nan didn't even know the distribution of the provinces and the neighboring provinces, let alone the Netherlands, which was far away in the world. Therefore, Zhang Nan also had no way to answer Comrade Li Er's question.

"It doesn't matter where he is, anyway, one day, this place is also my Datang, am I right or not? Jiro. Li Yuan said with a smile.

"Yes, what my father said is very true, one day, it will be my Tang Dynasty." Li Er echoed.

At this time, the two conquerors, the old and the young, reached a surprising agreement, although politically, in the father-son relationship, Li Er and Li Yuan are both contradictory existences, but as conquerors, both of them have a heart of conquest, and one is bigger than the other.

"Qingquan, what is this red fruit called? It's pretty tasty. Empress Eldest Sun asked.

The red fruit in the mouth of Empress Changsun is strawberry, of course, as a new type of fruit that only entered China in 1910, it is impossible for Empress Changsun to know.

"Back to the queen's mother, this thing is called strawberry, the queen mother should not underestimate this thing, although this thing is small, but the nutrition is very high, this thing is a good thing to treat loss of appetite, although it is a fruit, but it has medicinal value." Zhang Nan said.

"Oh? Qingquan, what you said is true? Can even this fruit be used in medicine? And what else is so effective? If there really is, then you have to give some to the old man, and the old man should take it back and study it well. ”

It was Sun Simiao who spoke, as the leader of Datang Medicine, plus Comrade Li Er's eldest grandson, Empress Sun, and Comrade Li Yuan's personal doctor, Sun Simiao was naturally qualified to participate in this centennial banquet.
