I was a village chief in a primitive society

Su Bai conducted experiments for several hours, until the afternoon.

I ate some lunch in the laboratory in a hurry, and it was just a bowl of noodles.

"It has been purified to this point, it should be almost done, right?"Su Bai said to himself.

He looked at several glass vessels on the table in front of him, which contained various liquids.

There were dark green, light green, yellow, and even some purple.

In short, these The colors of plant liquids after purification are different. The different colors may also represent differences in acidity.

"But the color looks pretty good this way."Su Bai nodded with satisfaction.

Wearing anti-corrosion gloves, he picked up the glassware and looked at the liquid inside, which was still shaking from time to time.

This was the result of his experiments for several hours. It is necessary to use plant juice to improve it. Many steps.

It also requires the use of a lot of materials. These materials can be found in primitive times.

In this way, it is not too difficult to extract the juice of plants, as long as it is done properly.

"Okay, now let's first try to see the individual corrosion effects of these plants."Su Bai murmured to himself.

He took out a few new stones, used a test tube to absorb a little bit of plant juice and dripped it on them.

When the system first came out with this set of chemical utensils, Su Bai felt that It is a bit useless.

After all, it will take many years to develop in the primitive era. How can I have time to do chemical experiments for him?

It is difficult enough to lead the people of the tribe to farm and learn civilization. How can I I had time to think about doing chemical experiments.

But by accident, Coco came to the Yanlong tribe. By the way, some chemistry books were given out one after another from the system.

This established the status of the current laboratory and allowed him to There is something to experiment with

"Zila, Zila......"

As soon as the purified plant fell on the stone, it made a squeaking sound.

The stone was visibly corroded, but soon it stopped making any sound.

The area of ​​corrosion is not that big, it's just a small area, and it doesn't look painful or itchy.

"The purified acidity is indeed pure enough, and the corrosive speed is fast enough. The only drawback is that the corrosive power is not strong."Su Bai frowned.

He experimented with several purified plant juices in turn, and the feedback was all the same.

Some of them were very corrosive, but the corrosion time was also very slow. It’s not much different before purification. The only thing that has improved is the corrosion intensity.

"As expected, a single acid is not enough; several kinds must be accumulated."Su Bai thought to himself.

He thought seriously for a while, and then took out glassware of various sizes one after another. He was ready to start the next experiment. The next experiment may be a bit dangerous.

After all, it is several The acids are mixed together, and sometimes they can hurt the skin if not handled properly.

"It’s another long experimental process."Su Bai took a deep breath.

He planned to fight with the laboratory to the end today. If he didn't experiment with a suitable acid today, he might not be able to sleep well at night.

Put away the large and small glassware There are many purified plant juices, and he plans to experiment with various methods.

The simplest is the mixing method, and then the distillation or fermentation method will be tried.

But this is not an easy task, the idea is of course It's beautiful, but it's risky to operate.

An explosion may occur if you're not careful, and some chemical reactions can be very strong.

But Su Bai didn't worry too much, because he had the innate skill of danger warning..

He can sense it quickly before the chemical experiment explodes, so he can avoid some wrong operations.

"I will try mixing the two acids first to see if there will be a violent reaction."Su Bai frowned.

He first poured out a little purified plant juice into a glass test tube, and finally prepared to add the second

"If the danger warning does not occur, it means that there will be no danger next."Su Bai then poured in the second plant juice with confidence.

The light green and dark green plant juices were mixed together, and the color became darker. At the same time, the liquid could be seen slowly bubbling out from the outside of the test tube. When you soak it, you will feel that the acidity is very strong.

But the bubbles will only appear for a while and then disappear, and it will calm down in just a few seconds.

"Isn't it invalid?"Su Bai raised his eyebrows slightly.

Do you want it to be so funny? The stronger acidity of the two is naturally useless when mixed together?

Su Bai didn't think too much, thinking that guessing for a long time is not as fast as experimenting.

Two juices The mixed acid was poured on the stone, and no sound was made this time.

Everything became very quiet, and this scene seemed a little embarrassing.

"Shouldn't it be a wait? If you have to wait, there is no point in mixing them together."Su Bai curled his lips.

I thought that the intensity of the two acids mixed together would be stronger, but I didn't expect that it would not be as strong as a single acid.

Time passed by, and the originally big sun outside slowly began to change. moonlight

"Knock knock knock......"

"Crunch!"

"Wu, it's dinner time. Let's have dinner outside tonight."Yu Ying expressed concern.

She was afraid that there would be smell everywhere in the laboratory, and it would definitely be uncomfortable to have dinner in it.

"good."Su Bai took off his anti-corrosion gloves.

He was still a little dissatisfied. He had wasted a whole day and still couldn't make good acid.

"Wu, why do you want to do acid all of a sudden? The weapons we have now are already very powerful."Yu Ying asked curiously.

When she saw Su Bai's expression, she knew that today's experiment must not go well.

The fox-eared lady felt that the tribe's weapons were sufficient anyway, and other tribes could not surpass them. , there is no need to be so nervous about making new weapons.

"This is called preparing for a rainy day. We cannot just be satisfied with the current status quo, but we must also consider the future."Su Bai said gently.

There are still more than 60 days until the rainy season. Once the rainy season is over, it means that the big ice and snow are coming soon.

Before the big ice and snow arrives, it is a period when tribes have frequent wars, because most of them Every tribe has to find a new tribe to 'host'.

Those tribes are like parasites. The tribe they are in now has been eaten out, so they have to find a new host quickly.

"So that's it."Yu Ying didn't quite understand the unfamiliar vocabulary she heard.

But Fox-Eared Girl knew it when she heard the last sentence. It's time to take precautions before they happen!.........................................
