According to modern historians, rubber was first produced in the Amazon rainforest of Brazil, and later Columbus brought rubber back to Europe when he returned from the Americas. Later, as the British colonial era began, they introduced rubber trees to Southeast Asia, where they opened plantations to produce rubber.

Therefore, according to modern history books, during the Tang Dynasty, it was indeed impossible for rubber trees to appear in Southeast Asia.

But the reason why Li Zexuan asked the Wang family's fleet to help find it was because he was gambling that there were wild rubber trees in Southeast Asia a long time ago, because Southeast Asia is blessed with unique climatic conditions, which is too suitable for the growth of rubber trees, which can be seen from a set of data.

Although the rubber tree originated in Brazil, in modern times, Southeast Asia accounts for more than 90% of the global distribution of natural rubber production, while Brazil, it is less than 1%!!

The reason for this pattern is that in addition to specific historical conditions, it is also inseparable from the unique climatic conditions of Southeast Asia.

Therefore, Li Zexuan is speculating whether there were wild rubber trees in Southeast Asia before the Tang Dynasty or even longer, and then became extinct for some reasons, and when the British colonizers introduced Brazilian rubber to Southeast Asia, the world thought that rubber was native to Brazil! 、

I have to say that the reason why he has this kind of luck psychology is that he is completely sick and rushed to the hospital, who let the current Datang no fleet be able to cross the Pacific Ocean and reach the Americas!

But luckily, his luck actually came true!

The Wang family's fleet really found wild rubber in Southeast Asia!

How does this not make him ecstatic?

At this time, he didn't care about waiting for the holy decree at home, and directly urged Wang Renbiao to walk towards the dock with him.

So, the tragic Wang Renbiao didn't sit on the bench as soon as he entered the house, oh, it should be that the sofa was not hot, so he was called out again!

..........................

"No, the rubber is in the barrel, and it's still on board! Xiao Xuan, wait, I'll ask someone to find a small boat and take you on the big boat to have a look~! ”

Coming to the wharf, Wang Renbiao pointed to several building boats on the river with the flag of the Wang family and said.

"Well, I'm tired!"

Li Zexuan thanked him.

Wang Renbiao smiled and turned to leave.

Li Zexuan looked at the scene on the dock, at this moment, compared to the morning, there are many fewer people and ships, and the five hundred official ships of the imperial court are all gone, it seems that Xiao Yu and Yan Lide have already arranged it, and it is estimated that most of the official ships are already on the waterway to Luoyang.

Although the official ships have been arranged, the task of the two court bosses is not over, and they still need to arrange officials on the spot to collect taxes on the merchant ships that have participated in the southbound sea trade, which is not an easy job.

I saw two old guys on the dock to let people set up a table to serve as a temporary office space, and there was not even an awning above their heads, compared to some people in later generations, these two were really shabby! But they are the real servants of the people, and they deserve everyone's respect!

"Uncle Yan, Xiao Ge Lao! You're still busy! ”

With respect for this kind of "revolutionary" of the older generation who really did practical things, Li Zexuan walked over and greeted the two.

"Yo! Xiao Xuan, are you here? The old man heard that you were named the founding marquis of the country by His Majesty in the early dynasty, congratulations! ”

Yan Lide heard this, looked up, and immediately said with a smile on his face.

He knows that his son Yan Shaoning seems to have a "target" in the academy, although the other party is not the daughter of the five surnames Qiwang or other high-ranking families, but that girl is the daughter of the contemporary Mo family giant, this is nothing to other families, but for the Yan family of the engineering family, it is very saying!

Well, in general, Yan Lide agrees with this marriage! He knew that his son was obsessed with construction machinery all day long, like an elm pimple, but he didn't expect that he would be "dealt with" now, which made Yan Lide happy at the same time, but also a little grateful to Li Zexuan.

Xiao Yu nodded and smiled at Li Zexuan, which was regarded as a greeting.

"Thank you, Uncle Yan! The prince or something, it's just Your Majesty's love! ”

Li Zexuan responded with a smile, and then he slapped his hand twice next to his face, and said to Yan Lide and the others: "On such a hot day, why don't you two let people build a shed?" If this is a good post, it will be a great loss for my Datang! ”

"Alas, how can there be that time!"

Yan Lide sighed, pointed to the endless boats on the river, and said:

"It's okay to say that the official ships of the imperial court have turned around directly to Luoyang, but there are more than 1,000 private fleets, and the value of the goods on their ships is very troublesome to count, and almost all the officials of the Ministry of Civil Affairs have been transferred here today, but even so, it is estimated that it is impossible for all of these ships to dock and unload before dark!"

When Li Zexuan heard this, he also felt that the amount of work Yan Lide and the others faced was really too large, especially those old officials in the Ministry of Civil Affairs, who still used a more traditional calculation algorithm, and the calculation speed was simply touching.

Although Li Er had issued a decree a few months ago to promote the new form of arithmetic throughout the country, it always took some time to receive and digest a new knowledge, and some people were older, so their ability to accept new knowledge was even worse, and the speed was slower.

"It's not a way to go on like this, Uncle Yan, Xiao Ge Lao, I'll send someone to help you build a few sheds in a while, and by the way, I'll send you some ice cubes and ice water, otherwise, it's not good if you suffer from heat stroke!"

Li Zexuan wiped his sweat and said.

Yan Lide and Xiao Yu don't have time to get this, but he has time! Looking at two old men who are over half a hundred years old, silently dedicating themselves to the country under the scorching sun, he felt a little uncomfortable. However, it is precisely because of people like them that Datang will gradually become stronger until it is invincible in the world!

The two old guys smiled, but they didn't refuse Li Zexuan's kindness, and the officials of the Ministry of Civil Affairs who were busy accounting for the accounts around them seemed to have heard the conversation here, and the action of writing in their hands at this moment couldn't help but be more cheerful.

"Yong'an Hou, the old man heard that you have a group of students who are quite proficient in arithmetic, why don't you call them over and help them fight?"

Xiao Yu raised his head at this moment, looked at Li Zexuan and said with a smile.

Since the implementation of the new arithmetic in the imperial court, he has also privately studied the arithmetic textbook compiled by Li Zexuan, even if he is as picky as him, he has to admit that the new arithmetic has an incomparable advantage in calculation speed, so he will say so now.

Li Zexuan was stunned for a moment, and then said with a wry smile: "Elder Xiao Ge, it's not that the kid is unwilling to cooperate, it's really my batch of students, and they are still training in the academy at this time!" I can't leave! ”
