However, after listening to Li Chengqian say that this thing can be used as a wheel, Lao Cheng became a little discouraged, and waved his hand to signal him what he should do, and stop staying here to make trouble. So Li Chengqian successfully got rid of Lao Cheng and returned to the back garden to take away Yang Yuxin, who had completed the task, of course, the curious little Lori was also among his peers.

Returning to the 'Lanruo Temple' to open the gate of the West Pond Courtyard, and gathering the Taoist priests who were obsessed with chemical experiments, Li Chengqian took out the sap of the fig tree that he had collected about a catty.

"His Royal Highness the Prince, what is this?" The original 'master' asked suspiciously.

"This is the sap of the fig tree, and your task during this time is to study this thing." After a long time, Li Chengqian already knew that the name of the 'master' was Yu Baiyu, but out of habit, he still liked to call this guy a 'master', not for anything else, just because of his momentum.

"What's there to study about this thing?" Yu Baiyu picked up the bottle, looked at it carefully for a long time, and asked suspiciously.

"What you're going to look at is how you can make this kind of stuff into a material that is very elastic and similar to beef tendon, but far more resistant to wear than cow tendon. This needs to be ......."

Based on his limited memory, Li Chengqian gave an explanation of the way to make natural rubber, but the more he talked about it, the more confused he became, and in the end, he went around himself.

"Your Highness, you, what you say is a bit wrong, right?" Yu Baiyu, who had been listening attentively to Li Chengqian's speech, also felt that something was wrong when he heard it, and couldn't help but ask.

"You don't care if it's right or not, anyway, that's what it means, give you five days, and after five days, the palace will see the finished product." Li Chengqian said angrily, on the one hand, he was because the 'master' didn't give him face, and on the other hand, it was also because he felt a little embarrassed.

In this way, Li Chengqian irresponsibly handed over the task of researching rubber, and at the same time told Cheng Xiaosi not to forget that he had to arrange someone to scrape the sap of the fig tree every day and send it to the palace.

The days passed slowly under Li Chengqian's endless tossing, and the rubber manufacturing work did not make much progress until half a month later, and he, the prince of the Tang Dynasty, had to face a historical celebrity - Songtsen Gampo!

"You're the Tibetan Zampu?" Li Er, who was above the main hall, looked at the little boy standing under the imperial steps, and suddenly became a little excited, and glanced at Li Chengqian, who was quite interested in Songtsan Gampo: "You two are of the same age, so you will receive him." ”

"Sons obey orders!" Li Chengqian walked out of his position, first glanced at Songtsen Gampo, and then respectfully saluted the old man.

The old people in the court were actually looking at this young man who was about the same age as Li Chengqian, and they did not raise any objections to Lao Li's arrangement. Left and right are just a doll, even if they are the lord of the country, what can they do? On the broken ground in Tubo, the birds don't, and its lord is not even as important as the lord of Gaochang in the eyes of the old goods.

In this way, Songtsen Gampo was given to Li Chengqian by Li Er like a piece of goods, and his subordinates were naturally no exception.

Songtsen Gampo, who has been in Zhenguan for seven years, is too young, and Li Er has no need to have the same knowledge as him, and he is just a child's ignorance as he said in the national letter, "If you don't see the princess, you should mention 50,000 soldiers to break Chang'an, kill Er, and take the princess".

Moreover, Tubo must be a newly established country, Li Er didn't even care about her at all, if it weren't for Li Chengqian's constant emphasis on how Tubo is, Lao Li would probably have forgotten about this country. Therefore, under such circumstances, it is understandable that Li Er handed over Songtsen Gampo to Li Chengqian to deal with.

In the main hall of the East Palace, Li Chengqian regarded this place as the place where he received Songtsan Gampo, although the ash was a little bigger, but it could still be used to sweep it.

"Sit down, don't be inhibited!" Looking at Songtsen Gampo, who was looking around, Li Chengqian sat on the main seat and gestured with his hand.

"In front of His Highness, how can there be a position for the ministers of the defeated army." Songtsen Gampo said in an unorthodox Tang official dialect.

Li Chengqian brought Songtsan Gampo here to talk about serious matters, where could he let him go, so he lowered his face and said in a deep voice: "If you want to behave well, this palace can give you this opportunity, but are you sure you can bear the consequences?" ”

Songtsen Gampo's face changed, and finally he took a deep breath and sat down on the chair that Li Chengqian pointed out to him: "I have long heard that His Royal Highness the Crown Prince is a disciple of the gods, and when I saw it today, I saw the dragon and phoenix among the people!" ”

"Don't talk nonsense, this palace said to Shang Nang at the beginning, if you are not convinced, you can come to Datang to find me, and now you are convinced?" Li Chengqian's implication was tantamount to telling Songtsen Gampo that all the arrangements for the Battle of Songzhou were in his hands.

"His Royal Highness the Crown Prince is strategizing, and the decisive victory is thousands of miles away, Songzan admires!" How can a person not bow his head under the eaves? Songtsen Gampo was no longer convinced, and no longer believed that this battle was commanded by Li Chengqian, but he had to say this in his mouth.

"I know you don't believe it, but it's okay, we still have a long life in the future, let's ride a donkey and read the record book - we'll see!" Li Chengqian shook his head absently, and said while motioning for tea to the only two maids.

There is no need for him to explain to Songtsan that the people sent to Songzhou are all arranged by him, and even if he says it, it is of no practical use, and Songtsan Gampo is also a generation of heroes, and if he can shout 'My Lord Shengming' because of Li Chengqian's words, then it is the most untrustworthy thing.

But despite this, Li Chengqian's attitude surprised Songtsen Gampo, and asked in a trembling voice: "You don't kill me?" ”

He had heard that the last guy who attacked the Tang Dynasty was now dancing for the Tang Emperor, and his guy who repeated the mistakes of the past would not end up better than the previous one. But now the prince of the Tang Dynasty actually said, 'The days are still long', this is not the way of speaking that wants to imprison him for a lifetime, how can he not be excited when he listens to it.

"I won't kill you, but it won't be so easy to let you go." Li Chengqian was very satisfied with Songtsen Gampo's current mental state, and when he thought of the appearance of a famous figure in history, wagging his tail and begging for mercy in front of him, the satisfaction in his heart was simply indescribable.

Of course, wagging his tail and begging for mercy is just Li Chengqian's own imagination, but what difference does this make, after all, Songtsen Gampo's life is now in his hands, and he can die at any time with the change of his mind.
