"Eight hundred bags, how can you need so many?"

In Sidondis City, which originally belonged to Ai Jin'er's underground laboratory, Elder Si Yao exclaimed in disbelief: "I have seen the formula before, and the dosage of acacia gum is not much. At this dosage, how many flame dogs are there to be infected with the disease?"

Gan Guyu, who was sitting next to the experimental operation table, replied while busy with the experiment in hand: "That old thing Tang Yan, in order to hide from us and the Guangyao royal family, deliberately created the illusion that the epidemic is getting worse. Today, there are no flaming dogs infected with canine plague, and there is really not one in a hundred. ”

Elder Si Yao exhaled heavily, "But in this way, the cost of buying acacia gum is even higher than the value of the Flame Dog, is it still necessary to treat it?"

"Whoever told me to let Arnold speak, this epidemic will definitely be solved. Gan Guyu smiled helplessly, "In fact, the biggest problem is that this acacia gum is priceless at all." Can we still buy it from Qiu Dalin?"

"And what are you?" said Elder Si Yao, confused.

"I don't know what the so-called acacia tree is, but if we can analyze the active ingredient of this acacia gum, we may be able to find a substitute for it. ”

Gangu Yu took out the acacia gum soaked in water and gradually dissolved into a viscous liquid, some of which were directly processed into slices, and some of which were put into the centrifuge left by Ai Jin'er, and after a series of treatments, they were put under the magic microscope one by one and began to observe carefully.

"These ...... Do they seem to be all polysaccharides?"

Gan Guyu looked at the image on the eyepiece display, and wrote and drew on the manuscript paper while distinguishing: "Hmm, this ring structure, one carboxyl group and four hydroxyl groups...... It's glucuronic acid, which is also six carbon atoms...... The carboxyl group is gone, this is a methyl group, right? Well, this is rhamnose......"

Elder Si Yao listened to it from the sidelines, and he couldn't understand what the terms that were in Gangu Yu's mouth were at all. Gan Guyu moved his neck for a while, and found that Elder Si Yao's face was confused, so he smiled and took out a stack of manuscript paper from the portable warehouse and handed it to her.

"What is this?" asked Elder Si Yao as he took the manuscript paper and subconsciously asked.

"The manuscript of the seventh volume of the Spring and Autumn Essentials was handed over to me for review by Lancel after the proofreading was completed a few days ago. Gangu Yu turned his head and continued his work, "You can take a look at the introduction of some monosaccharides and polysaccharides in Chapter 3. ”

"It's all compiled to the seventh volume......" Elder Si Yao's eyes lit up, and he hurriedly opened the manuscript paper and read it carefully.

It didn't take long for Elder Si Yao to understand Gangu Yu's intentions: "It turns out that most of this acacia gum is composed of these sugars?

Gangu Yu nodded: "That's it." ”

Elder Si Yao was overjoyed at first, and then worried, "However, can these ingredients really be found in other plants, and do we have the corresponding extraction technology?"

"I'm afraid there is no need for extraction and synthesis. ”

Gangu Yu stretched his waist and stood up, handing over a few pieces of manuscript paper to Elder Si Yao: "This is the approximate composition and content ratio of acacia gum. I'm still not sure if the acacia tree is a plant I know well, but I think I've found a natural alternative. ”――

Nature's Forest.

Thanks to its unique advantages in planting, large wheat fields that were previously destroyed in the war have now been restored to their original appearance. Most of the wheat in the field has already begun to tassel, and in some time, this winter wheat crop will also be ripe.

On the ridge of the wheat field, a beautiful girl in a sailor's suit was staring blankly at the undulating wheat waves in the wind. On her shoulder, a small green snake was crossed, squinting slightly and pretending to sleep.

After a long time, the girl suddenly sighed lightly, and the whole person fell listlessly. A few days ago, Tang Yan and his family members were escorted back and placed under house arrest in the back mountains. She thought that the people she was looking forward to should come back together this time, right?

Unfortunately, there is still none.

"Hiss-" Perhaps empathizing with the melancholy for the girl, the green snake on his shoulder also hissed softly.

"Don't you even think you're a little bored?" the girl nodded lightly on the little head of the green snake, and smiled solemnly, "You can't make a little petty, that guy is running around outside, it's very hard! we can't help too much, at least we have to make sure that we don't make trouble for him, right?"

When the green snake heard this, his eyes showed disapproval, and he raised his head proudly. For that guy's green plan, everyone was almost squeezed dry, didn't they help him enough?

The girl couldn't help but giggle with joy when she saw the human look in it. At this moment, the green snake suddenly turned its head suddenly, staring in one direction, and kept spitting out the letter.

"What's wrong Xiaoqing?" The girl was stunned when she saw this, and then she also looked vigilantly in the direction that the green snake was staring at, but she found nothing.

"Shhh

Seeing this, the girl was anxious and hurriedly followed: "Where are you going? Wait for me!"

Only then did the green snake turn around, spit out the letter at her, raised his little head to signal her to follow, and then ran out into the distance. One snake and one person rushed out of the entrance of the natural forest and came to the path leading to the outside.

"Hiss! hiss!" The green snake suddenly became excited, suddenly accelerated, and quickly disappeared on the other side of a corner.

The girl hurried up and caught up, but stopped abruptly after turning the corner, staring blankly ahead.

A young man in a red and blue checkered shirt and cropped jeans, kicking a pair of army-green flip-flops on his feet, was holding the green snake in one hand, and his face was teasing with joy. Looking up and seeing the girl standing around the corner, he couldn't help grinning: "Haha, brother is back!"

When the girl saw the comer, she felt a sour nose, and her vision blurred irrepressibly.

The young man was stunned when he saw this, and then ran forward in a panic: "What's the matter, is this? Wronged? Damn, who is so bold and dares to bully you!"

"No, no one bullied me......" The girl hurriedly wiped her eyes, "I'm here, I ran in a hurry just now-"

"So there's sand in your eyes, don't move, brother will blow it for you...... Are you feeling better?"

“...... Well. ”

"Silly girl, I still want to lie to my brother. There's no sand at all, right? Honestly, what's going on?"

“...... I don't know! I'm glad to see you, but I can't help but want to cry...... Isn't it humiliating?"

“...... Silly girl!" the boy touched the girl's head dotingly, threw the green snake on his head, and then picked the girl up.

"Ahh

"Hey, let's go, go home!" the boy smiled heartily, and strode towards the natural forest. (To be continued.) )
