Zhang Zheng started from Tianzhu, talked about Rome, and talked about Egypt about becoming an academic desert.

Speaking of present-day Persia, the Sassanid Empire stood in Central Asia for 400 years without falling. It also talks about the rise of black-clothed food in the south of the Sassanid Empire.

Muhammad had a Qur'an in one hand and a murderous sword in the other, pointing at the already crumbling Persian dynasty. Then I talked about a copper island in the south of Datang, and there is a continent in the south of copper island, where there are many big squirrels that are so tall and have a bag on their stomachs.

He talked about the Mayans, who had a glorious civilization in the Americas, and the potatoes and sweet potatoes that grew all over the mountains.

Corn that yields more than ten stones per mu is eaten with peppers that will be on fire in your mouth...... Zhang Zheng spoke very messily, and he said what he wanted.

It's all some memory fragments, and the right to make the child happy. Li Tai on the side put his hands on his cheeks and listened very seriously.

From time to time, there was an expression of surprise, surprise, and excitement on his face. It seems that I heard something terrible.

"Really, sir, is it true that there are squirrels that the size of a man, and that the Mayans still use human sacrifices?"

"Of course it's true!" Zhang Zheng was talking, and Li Tai would occasionally interject.

"The pyramids of ancient Egypt are so huge that they can't even insert a blade into it, what a lot of work it must be, and their country is too rich." When it came to gold, Li Tai's eyes were full of golden light, and his round little face was full of surprise.

"It is impossible and impossible to produce more than ten stones of grain per mu." Speaking of corn potatoes, Li Tai's round face showed a determined look.

It means that Zhang Zheng even deceived children.

"Muhammad, a thief, who does not believe in his doctrine will be killed by him, he is simply a tyrant, if it is in the Tang Dynasty, I will definitely beat him so that he can't take care of himself! There is also the Sassanid Empire, which can stand in the world for 400 years, it is impossible to be defeated by that great tyrant so easily! When Muhammad pointed his finger at Persia, Li Tai was filled with righteous indignation, as if Persia belonged to his family.

"Silver Mountain and Copper Island, as well as the archipelago full of spices, if Datang can get it, wouldn't it be rich?"

"......" said as he spoke, and before he knew it, a long time had passed. Zhang Zheng said a lot, and Li Tai also listened a lot.

Under the dim oil lamp, there is a pair of masters and apprentices who are really nameless, and they get along very harmoniously. Just like the old Li Gang and Zhang Zheng.

After talking about the history of European religions, Zhang Zheng picked up his cup and took a sip of water. Then he spread his hands and said, "It's over, it's gone!" ”

"Ah, that's gone!" Li Tai licked his lips, his face full of unfinished meaning.

"Smack... Syllable... Syllable! There was a burst of applause outside the unclosed door of Xiaotang.

"Wonderful, really wonderful, eye-opening."

"Huh?" The two people in the filial piety hall were stunned for a moment, and turned their heads at the same time.

"Your Majesty!"

"Father?" The person who came was Li Shimin.

"No need to be polite!" Li Shimin raised his hand and pressed it, and then walked straight to Li Chengqian's bed and sat down. Then he stroked Li Taiyuan's head twice and said, "Qingque'er, go and play with your eldest brother, I'll say a few words to Shenzhi!" Li Tai got up, as smart as he probably had guessed what his father was going to say to Zhang Zheng.

He arched his hand towards Li Shimin and said: "Father, the minister will retire first!" ”

"Go, go, go!" Li Shimin waved his hand, with a loving smile on his face. When Li Tai heard this, he waved his hand at Zhang Zheng and said, "Sir, I'm leaving." ”

"Hmm." Zhang Zheng nodded lightly. When Li Tai disappeared in front of the two monarchs and ministers, Zhang Zheng's face returned to calm.

He bowed his hand to Li Shimin and asked indifferently, "Why does Your Majesty have the leisure to come to the academy." As soon as Li Shimin saw his youngest son leave, Zhang Zheng's face changed, and he couldn't help but sigh slightly in his heart.

did not answer Zhang Zheng's question, but asked Zhang Zheng: "Is there still a grudge in my heart in my heart!" He said yes, but his tone was extremely affirmative.

He didn't know that because of the matter of Lao Li Gang, Zhang Zheng's heart had already had a trace of estrangement from him.

It's just that sometimes, even if he is the emperor, there is no way to do everything perfectly.

"Weichen doesn't dare!" The corners of Zhang Zheng's mouth twitched, and he replied lightly.

"Don't you dare?" Li Shimin's expression was a little haggard, and he did not continue the topic, but talked about his intentions.

"I heard that the academy is going to hold a big exam recently, so let's take a look, by the way, let's take a look at Lao Li Gang, and also take a look at you."

"Thank you, Your Majesty, it's very good." Zhang Zheng's tone was still neither salty nor light, with a hint of alienation in respect.

Li Shimin was silent for a while, and Zhang Zheng was also silent. The two sat silently opposite each other. Zhang Zheng really didn't have anything to say to Li Shimin, and now the grave of old Li Gang is standing quietly next to this filial piety hall.

At this time, it is pointless to complain and talk. After being silent for a while, Li Shimin took the lead and said, "Shenzhi, I don't know where you went to learn an unpredictable skill. I don't know where you learned about what you said to Qingque'er. I don't plan to get to the bottom of it, everyone has their own secrets, you have them, and I have them. Now, I just want to ask you, the high-yield grain you talked about, as well as the Silver Mountain Copper Island, are they true? When you and Cheng Qian talked about these things, I only thought it was a joke between the two of you. But now you're swearing to Qingque again, I'm really puzzled! Li Shimin doesn't plan to get to the bottom of it, which is indeed a good thing for Zhang Zheng.

Otherwise, Zhang Zheng would have to make up nonsense to deal with it. After a pause, Zhang Zheng nodded lightly and said, "It's true, it's just that now with Datang's navigation technology, wanting to reach the Americas is tantamount to a fool's dream." Instead of thinking about the high-yielding grains, Your Majesty should start introducing the three crops of rice that I mentioned to His Royal Highness the Crown Prince. As for Yinshan Copper Island, Yinshan is in the territory of the Wa Kingdom, whether it is true or not, His Majesty only needs to send a sailor to log in to the Wa Kingdom, and you will find out at a glance! After speaking, Zhang Zheng fell silent again.

After Li Shimin listened, he lowered his head and pondered for a while. said to Zhang Zheng: "I, naturally, I want to send someone to check the authenticity, you don't have to worry about the matter of the three crops of rice." I have already found out that there is indeed rice in the territory of Zhenla that can be cultivated three times a year, and it will be introduced in the near future, and it will be handed over to Feng Ang to try to plant in Lingnan. Zhang Zheng meticulously bowed his hand and replied: "Your Majesty is old, so it is naturally better!" ”

"Alas~" Seeing Zhang Zheng's attitude so respectful, Li Shimin sighed again. Then he asked, "Qingque'er is here, I didn't cause you trouble!" ”

"No, Qingque is smart and astute, and there are students Ruosi, and the minister is lucky."
