I was a village chief in a primitive society

"Sign in to the system and receive your assistance package."Su Bai shouted to the system in his heart.

"Ding! Congratulations to the host for successfully signing in"

"Ding! , congratulations to the host for receiving primary aid: a fine whetstone. Su

Bai twitched the corner of his mouth a few times and said helplessly:"Okay, although there are grindstones everywhere, the ones produced by the system are always good."

He could only comfort himself in this way, otherwise he expects the system to always have good things every day? This is not realistic.

After all, he has only obtained the flame control technique not long ago, so he should be content. He got up and went to the restaurant to finish breakfast, and was ready to go Take a look at Coco’s research results in the laboratory

"Crunch!"

Su Bai first knocked on the door and then slowly opened the laboratory door. He originally wanted to wait for the other party's response before opening it, but the other party did not respond for a long time.

He immediately understood that the other party must be obsessed with research. That’s why I didn’t hear the knock on the door outside.

"What are you doing that makes you so absorbed?"Su Bai said gently.

He slowed down his pace as much as possible and kept his voice as low as possible, just to avoid letting the other party suddenly be frightened.

"The witch is coming."Keke immediately prepared to stand up.

She really didn't hear it. Her golden eyes were always looking at the materials on the table. Coco's breakfast was specially brought in by Yuying for her. Originally, the fox-eared lady wanted to put it down and wait for the other party to eat. Come back and collect them after you finish.

Who knew that the blond girl was so direct that she finished the wheat porridge in one go, and even the fried wild eggs in one go

"It's okay, just sit back. How far has the research on banknotes reached?"Su Bai pressed the other party's shoulders and sat down.

Keke sat down embarrassedly, and said with a slightly red face:"Wu, the research on banknotes has already become somewhat obvious. You are here just in time, so you can check it out by the way."

The blond girl has almost finished her research. She was going to report on her work in the afternoon and wanted to continue to improve.

"oh? So fast? Tell me about it."Su Bai said lightly.

It's only been a few days, and he felt that the blond girl's progress was pretty good.

"It's all because of the wizard's papermaking skills and the help and cooperation of other people, otherwise it really wouldn't be so fast."Coco smiled sheepishly.

Indeed, the tribe's workshop has always been very cooperative with her, and the people in the tribe will do their best to meet her needs.

This also saves Coco the time of constantly looking for materials. For this reason, she even made a special trip to the papermaking workshop to see how paper was made.

Of course, this was mainly to study banknotes, and it was also with Su Bai's permission, otherwise she would not dare to go to these forbidden places.

But that's right. It was because she went to the papermaking workshop, and many things she didn't understand before were instantly understood.

The reason for the faster progress was that she fundamentally understood the production of paper, so that she could control the quality of raw materials.

"As long as it can make banknotes available, visiting the workshop is a trivial matter."Su Bai smiled faintly.

"Wu, take a look at these pieces of paper first and see if the talisman matches the quality of the banknotes in your mind."Keke immediately took out the results of the past few days from the drawer.

She spent the whole day running between the laboratory and the workshop, and the research results were tightly shut in the drawer.

It was even locked, that lock It was Su Bai who drove it from the system, and the blond girl even hid the key close to her body.

"The paper quality of these sheets is indeed quite good, but this one is not good, it is a bit too thick and heavy. I haven’t even picked up a few banknotes yet. Isn’t it a big stack in my hand?"

Su Bai eliminated the first one and started to look at the following papers. He read four or five papers before he saw one he was satisfied with.

"This one is pretty good. You see, the thickness is just right and the toughness is also very good."

Su Bai got some water on it, observed it for a while and continued:"The waterproof performance is also very good. Even if it is stained with water, it will not have any effect at all. This is the best raw material for paper."

He was really excited for a while. After studying it for so long, he finally saw good raw materials, which also means that banknotes will be promoted soon.

"I also think this one is the best. This paper combines three raw materials to achieve what it is now."Keke was very excited.

Even if the previous ones were rejected, it is good if one of them is confirmed now, and her efforts will not be in vain.

"Which materials?"Su Bai asked curiously.

He could guess that this paper was made of several materials, and the quality of the paper was different when he held it in his hand.

"The three main materials are orange tree pulp, wheat pulp, and stone thorn tree pulp. These three raw materials must be mixed in strict proportions."

Coco's face was full of excitement and she was dancing."In addition, we need to add some various small materials, and the proportions must be fixed, so that we can achieve what it is now."

She immediately opened the drawer and took out the notepad. On it were the proportions she recorded. Although the writing was crooked, it was still understandable.

Su Bai looked at the notepad and was very satisfied and praised:" You did a good job this time and helped the Yanlong tribe a lot. What reward do you want?"

Sure enough, he was right about the blond girl. There was a lot of data written densely on the notepad. It was obvious that every ratio was being registered.

Moreover, the other party helped research the raw materials of banknotes, so it is only normal to give some rewards..

Coco shook her head repeatedly and said happily:"No need for witches, this is what I should do, and I have to repay the tribe, without any reward."

The Yanlong Tribe not only saved her life, but also helped take back the Haiyu Tribe. These two are enough for her to serve the Yanlong Tribe unconditionally.

"One code equals one code. This is the reward you deserve. Tell me if there is anything you want?"Su Bai insisted.

Of course he knew what the girl was thinking, but that was all in the past. Now that he is willing to work for the Yanlong Tribe, he must still give him the reward he deserves.

"Wu, the paper currency has not been fully developed yet. When it is finally fully released, I will ask Wu for a reward."Coco resisted.

Only the raw materials for the banknotes have been solved, and the coloring problem has not been solved, so there is no way to accept the reward with peace of mind so early.

"Do you have any idea about the coloring issue?"Su Bai saw that the other party insisted, that's all. It will be the same if he gives again in the future.

"There is nothing new yet, but I have already asked people to start collecting raw materials for me. I believe there will be good news in a few days."Coco said firmly.

Su Bai rubbed the other person's head and said gently:"I know, have a good rest today and don't stay in the laboratory anymore."

"But witch......"

Coco wanted to say something, but was interrupted by Su Bai's gesture.

"Rest first, otherwise the lab will be confiscated."Su Bai made a silent gesture.

"yes."Keke had no choice but to compromise. There was no other way. Who made the laboratory important to her?.........................................
