Pu Zhen and 400 people have been trapped in the area of Bodaling for a day and a night, in order to rescue as soon as possible, Mu Lingfeng first led 200 soldiers to march quickly, and Lu An, Qingchen, Erma and others led people to follow.

It was almost noon, Lu An and the others rushed to the prairie near Bodaling.

"Brother An, from here on, all war horses will wear wooden chewing cages."

Qingchen pointed to the endless prairie in front of him and said, "This Boda grassland is extremely vast, but unfortunately, the grass here is not suitable for grazing.

Once a horse or sheep eats the grass here, they will inevitably die of fullness.

Because the grass at this time cannot be digested at all.

It is precisely for this reason that the small country of Shanhuan has always been independent in the middle of the grassland and has not been invaded.

Unexpectedly, after Bai Yangshu and Long Sen were cornered this time, they chose to occupy Shan Huan Kingdom.

Of course, as long as the war horse wears a wooden chewing cage and brings enough forage, Long Sen and them hide in Shan Huan City, which is equivalent to a dead place! ”

After listening to Qingchen's explanation and looking at the vast grassland, Lu An couldn't help but sigh secretly, the small country of Shan Huan guarding the Boda grassland can be regarded as a gift from nature.

It's a pity that in the end, that small country with a population of less than 200 still couldn't avoid the fate of being wiped out!

"Let's go, we brought so many people this time, no matter what, we can't let Long Sen and Bai Yangshu run away anymore!"

After walking for nearly an hour, I finally saw a lonely town in the heart of the Boda steppe.

From a distance, you can see that Pu Zhen and Mu Lingfeng, a total of 600 black-armored soldiers, have broken through the city gate and are fighting fiercely.

"Fence up, don't let them run away!"

Lu An gave an order, and the two hundred people who followed him rushed over like a wind.

Lu An jumped off the war horse and picked up a palm-high, somewhat yellowed peculiar weed.

"Brother An, don't touch this kind of thing, dirty."

Qingchen reminded.

However, Lu An had already twisted it with two fingers.

Sure enough, the black weed juice was squeezed out, and it was still a little sticky.

Put it in your nose and smell it.

Well?

"What's wrong? Brother An? ”

Qingchen also jumped off the war horse and came over.

"Qingchen, do you know what this grass is called?"

Qingchen shook his head, "The Boda grassland has always been a forbidden area for herders, and they don't like to touch the grass here.

However, as far as I know, the residents of Shan Huan are very fond of using this grass and grass roots to make fires for warmth in winter.

Although the weeds are flammable, they have a pungent smell when burned, and thick black smoke emits, so most people do not use them to keep warm unless they have to. ”

"Hehe, that's right!"

When Lu An heard this, he was even more sure of what he was thinking.

Throwing down the weeds, Lu An raised his eyes and looked around, feeling more and more excited.

"Qingchen, after you go back, you sent a proclamation to tell the people that if anyone is willing to come here to collect this weed, I will buy it at a high price.

Moreover, not only the weeds, but also the roots of the grass, and even the seeds of the grass.

If it's grass seeds, five taels of silver a catty! ”

"What?" Qingchen was stunned.

Like Lu An, he looked at the endless weeds around him, and glanced at Lu An again, although he didn't say anything, his expression was as clear as if he was looking at a fool.

However, the next moment, Qingchen's eyes turned red.

"Brother An, I know you want to help me, but you don't need to use this method.

After two years of rebellion, although the national strength of Qiuzi has weakened, it will not be unable to hold on.

This time, it would be good for you, Sister Lingfeng, and General Pu to help me recapture Qiuzi. ”

Lu An shook his head, "Qingchen, you misunderstood. ”

Lu An glanced at Erma, who was listening with his ears pricked up next to him, and pulled Qingchen as he walked, and whispered, "I didn't buy this weed, but because the value of this grass is really high. ”

"You may not know, but in fact, this is called wild chrysanthemum grass, as long as it is processed, it is quite versatile."

"If it weren't for the fact that this place is too far away from the Central Plains, I would really want to dig up all the wild chrysanthemums and grasses here in one go."

"Later, I will let Mifflin and Bachier be mainly responsible for purchasing these wild chrysanthemums and sending them back to the Central Plains."

"If possible, I will also plant this grass in large quantities in the Central Plains."

"In short, as long as you have this grass, it is not difficult to earn as much money as you want."

"As early as when I was in Loulan City, I mentioned to Mifflin and Bachier that I would cooperate with them and you in the future."

"As for the profits, you can talk to them yourself when the time comes, even if it is divided equally, it will be a lot of wealth."

"Let's put it this way, if the cooperation goes well, it will take two years at most to make your Qiuzi City rich!"

"This ...... How can it be! Qingchen was shocked by the picture drawn by Lu An, and regardless of how dirty the wild chrysanthemum grass juice was, he pulled one out and looked back and forth.

Lu An pointed to the rhizomes as thick as radishes of wild chrysanthemum grass and said, "If it is not convenient to transport, you can ask the people to collect these rhizomes later." ”

Qingchen couldn't help but be curious, hesitated and asked, "Brother An, can you tell me, what is the use of this thing?" ”

"Hehe, it doesn't hurt to tell you."

Lu An smiled, and twisted the black juice of the wild chrysanthemum grass again with his thumb and forefinger, "See, isn't it sticky?" ”

"You mean...... Use it as glue? ”

"Hmm." Lu An nodded, "Making glue is just one of its most inconspicuous functions. ”

Lu An recalled the information he had read in his previous life, and explained with a smile, "Actually, the juice of this wild chrysanthemum grass, the exact name, should be called rubber!" ”

Lu An didn't expect that he would find wild chrysanthemum grass that can produce natural rubber here!

As a judge of the beauty contest, Lu An has learned a lot of knowledge, and he happened to see the introduction of natural rubber.

In the whole world, there are only three kinds of plants that can produce natural rubber.

Among them, the most productive rubber trees were still on another continent at this time.

And wild chrysanthemum grass, although the yield of natural rubber is not high, but so many wild chrysanthemum grass on this Boda grassland is enough to refine a huge amount of natural rubber!

Unexpectedly, the wild chrysanthemum grass, which is called the natural protector of the Shan Huan Kingdom by the people of the Western Regions, has been abandoned here as waste.

Of course, even if someone finds out that the juice of wild chrysanthemum grass can be used as glue, he will not worry about someone stealing this business.

After all, the curing process refined by rubber is not something that people of this era can figure out.

Even in later generations, it took hundreds of years for the rubber curing process to be mastered by humans!

"Qingchen, in addition to this wild chrysanthemum, there is a more profitable business.

These two businesses alone can give you a firm foothold in the Western Regions! ”

Immediately afterwards, Lu An posted it in Qingchen's ear and explained his planned business in detail.

"......" After listening to the business that Lu An said, Qingchen's whole person was petrified.
