I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Liu Tan looked up at Liu Che, swallowed and said, "That's... the idea I just came up with. Didn't Erchen open a school? No one knows whether those students have studied hard, so I plan to pass the exam." To verify, the in-class test is a test that is set after the master's class reaches a certain point, in order to clarify the students' mastery of the knowledge, and it can be done at any time, depending on the master's mood."

Although it was nonsense at the beginning, when it came to this point, Liu Tan's thinking became more and more smooth, and he continued to explain: "The monthly exam is fixed once a month, and the final exam is based on the school year. Take the exam once, the mock exam is...a form of simulated entrance exam, as for the entrance exam...I haven't really thought about it yet, but I have a preliminary idea."

Liu Tan really can't make it up for the entrance exam, there is no way, other things can be made up, but the academy is already the highest school in the northern border country, where can I go to?So it can only be so vague.

Liu Che laughed when he heard this, and always felt that Liu Tan moved all the things he had experienced here, and was going to let those students feel the fear of being dominated by the exam.

But there are some things that cannot be broken even if they know each other well.

Because there is no benefit, Liu Che knows that Liu Tan will definitely not tell all the things about the fairy world, and if he really exposes it, it will only make things difficult for the child. What if the child runs back in agitation?

So it's good as it is now, anyway, Liu Tan himself is in a daze, and he often slips up.

If it weren't for the fear of Liu Tan's poor health, Liu Che would really be like getting Liu Tan drunk again, maybe he would be able to know more.

After Liu Tan finished his nonsense, he saw Liu Che looking at him indulgently, which made him tremble with fear, so he changed the subject and asked, "Father, do you want to stay here for two days or go back?"

"Go back, it's getting hot."

Although the northern border country is not that hot, the temperature is only a little lower than Chang'an, but the sunshine here is relatively strong, so it is still very hot when it should be hot.

Liu Tan smiled and said, "Okay, I'll make you some ice cream when I go back."

As soon as Liu Che heard it, he knew that there was probably something new to eat, and he couldn't help being a little curious for a while, so he immediately set off and started to rush back.

After returning home, Liu Tan asked someone to bring over shaved ice.

The crystal clear glass bowl paired with white smoothie and brightly colored jam looks really appetizing.

Speaking of this jam, in fact, after any fruit is made into jam, the color is not particularly good-looking, as if it has faded.

Liu Tan had no way to start making various food colorings. For example, boiling peach skin in water and mixing it with jam can add some pink color, but it is limited.

At this time, the original color of the brown sugar can improve the color of the jam a lot, so Liu Tan simply didn't use white sugar to make the jam.

Liu Che took a spoonful and put it into his mouth. The jam was sweet and sour, and the smoothie was cool but not too much. Everything was just right.

Liu Che looked at the delicate smoothie and said with a smile, "I'm afraid people have prepared it long ago?"

Liu Tan immediately said: "How can I do it? Of course it is made now."

Liu Che raised his eyebrows. It is not easy to make ice sand so delicate. How long does it take to chisel it manually?How can I do it now?

As if seeing Liu Che's doubts, Liu Tan asked someone to bring over the shaving ice machine that he had made earlier, and brought over a lot of ice along the way.

Liu Che is very interested in the shaving ice machine, especially the appearance of this shaving ice machine is too cute, which makes him like it even more.

Liu Tan leaned over to him and showed him how to use the shaved ice machine. As the fine smoothies filled the glass bowl below, Liu Che was aroused a little bit of childlike innocence.

Seeing his addiction to playing, Liu Tan lay down on the table, his eyes looked rounder because he looked up, and asked with a smile: "Father, is this fun?"

It's very fun, there aren't many things to play with these days, otherwise Liu Che wouldn't have gotten a siphon toilet and had a good time.

He grinded three bowls of smoothies in a row, and Liu Tan stared at him for fear that eating too much would be bad for his health.

Fortunately, Liu Che just likes to play, and he himself knows not to eat such cold things.

After Liu Che had had enough fun, Liu Tan muttered, "I'll send some older ones to Chang'an later, so that the queen mother and His Royal Highness the crown prince can also cool off."

Liu Che raised his eyebrows after hearing this: "You don't count as your seventh brother?"

Liu Tan was at a loss for a moment after hearing this, and almost blurted out: Who is the seventh brother?

Fortunately, he reacted quickly, and remembered that this seventh brother was his father's new youngest son, and he had used this child to advertise Dunhuang Jade before.

After thinking about it, he immediately smiled and said: "Seventh brother is still young, with a weak spleen and stomach, and can't stand the cold."

Liu Che snorted lightly: "It's really considerate."

Liu Tan was a little confused, what's wrong?

He scratched his head, thinking of the crystal house he had built a few days ago, he couldn't help laughing: "If Father is bored, I will take you to a good place."

Liu Che raised his eyebrows: "What a good place."

Liu Tan stood up and said with a smile, "Father and son come and see."

Liu Che didn't ask any more questions, got up and followed Liu Tan.

When I walked halfway, I saw that the place they were going to was Xiaogangchi, and I realized something.

He knew about the Glass House, and his son would never hide anything from the embroidered messenger, so Liu Tan and Lu Xuan went to play in the Glass House on the first day, and Liu Che knew about it within a few days.

At that time, he was also curious, but he was busy with his affairs, so he quickly threw it behind him.

Now he followed Liu Tan step by step towards the rockery, watched him open a door on the rockery, and then walked down little by little.

Although there are torches in the passage, it still looks very dark. In addition, the sound of water can be heard faintly, and the smell of damp can be felt.

If you don't know that there is something hidden in it, you may think it's some kind of ghost story.

However, when the stone gate at the far end was opened, the eyes were bright, green as far as the eye could see, the plants in the glass house, the clear pool water with a little bit of blue outside the glass, and the faint light formed in the water by the sunlight, Even though Liu Che knew that there was such a place, he still couldn't help thinking that he had come to the real Crystal Palace.

The magnificent scenery in front of him kept Liu Che silent for a while. As a person who has been well educated in literature since he was a child, and can even write poems for thousands of years, this is the first time he knows that when beauty reaches a certain level, there are no adjectives to describe it. .

The glass house that Liu Tan built for Liu Che has improved a lot compared to the previous technology, and because of the glass blowing technology, the roof beasts are also made of transparent glass, which can faintly reflect a little light underwater.

It's different from the last time it was arranged for Lu Xuan, because this glass house is a little bigger, Liu Tan even separated the dining room and the lounge.

There was still a swing in the lounge and because it was spring and summer, he even had some butterflies brought over.

Liu Che walked up to the glass and carefully reached out to touch it, as if he was afraid of breaking the glass.

The glass tentacles are icy cold, and the rippling light reflects on the hands like light fish swimming.

And at this moment, Liu Che saw many colorful fish.

He is not unfamiliar with these fish, they are all colorful carp, and there are many in the warehouse pond of Weiyang Palace.

It’s just that the feeling of watching it on the water bank is completely different from watching it underwater. You can see more clearly how flexible these fish are in the water, and some fish even come over curiously to look in through the glass. You can see the patterns on the fish more clearly.

For Liu Che, this kind of experience was too fresh.

He smiled and said, "It seems to be much cooler underwater."

Liu Tan thought for a while and decided not to "deceive the emperor". He pointed to the ice basin in the corner and said, "It's not because of the water, but because of the ice."

In fact, there is not much ventilation here, even if it is not too hot, it may make people feel stuffy, and it will be comfortable only after the temperature drops.

Liu Che walked around, and after looking around for a long time, he was finally a little tired, but after he sat down, he started to stare behind Liu Tan for a long time.

Liu Tan looked behind him subconsciously - there was no one else except Bi Gao who followed him down to serve him.

His father's eyes didn't seem to be focused on Bi Gao either, Liu Tan's hairs stood on end for a moment, thinking that Liu Che had seen something, he couldn't help asking cautiously: "Father, what are you looking at?"

Liu Che retracted his eyes and smiled, "I'm looking to see if you have a tail."

Liu Tan:? ? ? ? ?

Liu Che is different from Lu Xuan, he is more curious than Lu Xuan.

What Lu Xuan felt when he entered the glass house was Liu Tan's love for him, and his heart was filled with happiness so he didn't think about anything else.

But after Liu Che was aroused by the novelty, he felt that although the scale of the glass house was far from the imagined Crystal Palace, the real Crystal Palace should look like this, at most it would be bigger.

As for the door...it must be because they are all mortals, so they were transformed into this way.

Liu Che thought that unless he had seen such a place, how could he make such an exquisite crystal house?

Not to mention glass, there are always crystals. It is indeed extravagant to use crystal to make a house, but not to mention princes and kings, even some rich people can do it. Building such a house?

But no one thought of building this kind of house underwater, because they had never seen it before, so they couldn't think of it.

So Liu Che's brain hole opened to whether his son was a spirit in the water?

Liu Tan didn't know what Liu Che was thinking, and when he heard him check whether he had a tail, he didn't know what expression to use to face him, so he could only say expressionlessly: "You and the queen mother don't have one, so naturally my son doesn't have one either."

Liu Che chuckled, and didn't pursue too much, just said: "Sooner or later, it should be revealed."

Liu Tan: The emperor's brain circuit seems to be really different from that of ordinary people.
