Li forgot to worry and thought about it. He didn't figure out any way to make the four-wheel carriage pass through the desert.

In fact, the best way is to make rubber.

But the rubber tree is far away in South America. Now where does Datang go to find it?

Of course, in addition to the rubber trees in South America, there is also a plant that can be replaced in China, that is rubber grass.

Rubber grass originated from China, Xinjiang and other places can extract rubber.

Li forgets that the rubber grass cultivated in later generations can extract 70 kilograms of rubber per mu. Rubber trees are 80 kilograms per mu, with a slightly lower yield per mu.

But the rubber grass is far away in the western regions and can't hydrolyze near thirst.

Moreover, how to extract rubber from rubber grass, Li forget worry is also a black eye. Now that the army is about to start, where is the time for him to do experiments?

After he led the western expedition, laid down the western regions and established the Anxi capital guard, he should order people to collect and plant rubber grass. Even if the output is lower, it is worth it as long as we can make rubber.

But now it's useless to say that. It didn't help him at all how to get the wagon through the desert.

Seeing Li forgetful and sad, Cheng Yaojin smiled more and more happily.

"Ziyou, don't think about it any more. Honestly lead the army to conquer the western regions. If you want to be a woman, take your concubine Hu Ji with you. If you can't do it again, there are many beautiful women in the western regions. What's wrong with being a woman, big husband!"

Li forgot to worry and was so angry that he had nothing to say. Cheng Yaojin, an old rascal, should be caught and soaked in a pig cage!

However, even if he was unwilling to do so, he had no other way.

Even after returning to Dingzhou village, Li forgot to tell Su Changqing about his conversation with Cheng Yaojin today.

How disappointed would Su Changqing be if he learned that he could not return to Chang'an within eight months?

Although the beauty boss is only two months pregnant, Li forgets worry and doesn't dare to take risks, which makes her sad because of herself.

Li forget worry just asked Niu Wu to select several clever episodes from the house and teach them how to make vacuum packaged food, lunch meat, instant noodles and so on. He asked them to set out in advance, take the order of their marching chief manager, and hurry to Jingzhou, so that the western expedition army immediately began to prepare military food according to the method he taught.

As for the subsequent production of military grain, Professor Li Qieyou gave it to Yan Liben and asked him to teach it to the Ministry of war. All the grain, grass and baggage transported to the western expedition in the later stage should be replaced with these military grains.

The reason why Li forgot to worry about such an important matter did not go directly to Li Er to report it was that he was angry in his heart.

Angry Li Er deliberately pits himself. Angry Li Er makes himself unable to accompany Su Changqing, so he is deliberately angry. He just orders someone to send a message, but he avoids it.

But how could Li Er not pay attention to such an important thing.

After the Ministry of military made a batch of military grain according to the method taught by Li forget you, it was immediately presented to Li Er.

After tasting these "delicious foods", Li Er was naturally overjoyed. On that day, he led a group of national leaders to Dingzhou village.

Li Er's Royal driving arrived. Li forgets his worries. Even if he is no longer uncomfortable, he can only go out of the house to meet him.

"I've seen your majesty."

The goods were also angry. Even my little nephew didn't claim to be angry. He gave a gift to Li Er according to the etiquette of his courtiers visiting the king.

Li Er looked at him in surprise, even though he understood Li's careful thinking.

"Hehe, Ziyou is blaming me?"

"I dare not."

"Dare not?" Li Er fiercely knocked chestnuts on Li forgetful's head: "I don't see where you dare not! Dare to throw your face at me. Believe it or not, I will immediately order someone to twist you to the Li main hall and let the queen teach you a lesson?"

Hearing the speech, Li forgot to worry. His face became more bitter and hurriedly begged for mercy.

"Your Majesty... Oh, no, uncle, it's my nephew's fault. My nephew knows it's wrong."

He who knows current affairs is a hero. When it's time to recognize counseling, he still recognizes counseling to ensure peace.

If empress Chang sun talks about it, it's really torture... Li forgetful would rather go to jail in the imperial historian's Taiwan prison than listen to empress Chang sun's talk.

"Hum, next time, I won't spare you! Lead the way to your castle terrace. I'll also have cold beer today!"

Li forgot his worries and was speechless. Sure enough, the dandies were bigger than each other. It's estimated that all Chang'an city knows about drinking iced beer?

In fact, his guess is not wrong at all. Even smart merchants in Chang'an have learned to roast kebabs, and many restaurants have launched barbecue dishes.

In addition to the fact that no one can brew beer and can't supply it for a while and a half, barbecue soon became popular in Chang'an City, and even spread to the surrounding states and counties.

Cheng Yaojin had a big mouth and laughed at the speech. He said proudly, "Your Majesty, you came to my house a few days ago and brought me a few barrels of beer to honor me. Although the beer tastes light, it's quite refreshing to drink when it's chilled! Your majesty and your lords need to drink more today."

His words, both inside and outside, showed a sense of anger. It was obvious that Li Er and Yuchi Jingde did not drink beer.

Li forgot to worry. He was so angry that he rolled his eyes and became paralyzed. The beer he had sent to the Duke of Lu should be poured out to feed the dog!

Didn't this meow give him eye medicine naked?

Sure enough, Li Eryi's face was unhappy when Cheng Yaojin said this.

"Ziyou, why don't you send me some beer into the palace?"

Why?

Don't you have a little force in your heart?

You didn't force me to eat sand in the western regions. Wouldn't I bring you beer?

Li forgot to worry, but his eyes were almost turned to the sky, but he could only show an expression of fear: "my uncle wronged my nephew. The beer was only brewed soon. My nephew had to find someone to try it first. Would he be hysterical after drinking this wine? My uncle's dragon body is important. How dare I offer wine at will?"

"Ha ha, Ziyou's right!" Li Er was very happy when he heard the speech. He turned his head and glanced at Cheng Yaojin: "some old people have rough skin and thick meat. It's best to try wine!"

The national leaders who didn't drink beer also laughed. They all began to tease Cheng Yaojin, an old rogue, with words. They were so angry that Cheng Yaojin, who had just been proud, turned black.

"Ziyou, come here, I'm making out with you today!" Cheng Yaojin rubbed his hands and looked at Li forgetful, ready to take it out.

Li forgot to worry. Naturally, he had long prevented the old hooligan from getting angry. He quickly dodged behind Li Er and attracted another burst of laughter.

After laughing, the little embarrassment between Li forgetful and Li Er dissipated.

Li Qieyou invited everyone to the castle terrace and ordered people to bring barbecue and iced beer. Everyone ate and drank and drank until they were drunk. Li Ercai talked about military food again
