I was a village chief in a primitive society

"Bangla, bangla......"

"Wow!....."

Pieces of broken ice cubes were placed in the cup, and a cup of dried tea was poured in.

The ice cubes were instantly covered with dense water droplets, and bubbles floated up.

"Wu, is this okay?"Yu Ying's pink eyes widened.

The fox-eared girl brought her face very close to her and looked at the glass of ice tea carefully. She was very curious.

"Well, give it a try, it’s considered cold brew tea."Su Bai smiled slightly.

He also picked up a cup of tea with ice cubes and drank it. Overall, he was very satisfied.

It felt cool after drinking it, and there was also a faint tea aroma, quite like a cold brew tea.

"It tastes really good. It's ice cold and very comfortable."Yu Ying was so happy that she kept wagging her fox tail.

This was the first time she drank something iced on a hot day, and it was tea.

This feeling was so wonderful that she became intoxicated after just one sip.

"It has a strong tea flavor and is so comfortable to drink."Yanhua shuddered deeply.

Although her teeth were a little bit frozen, it felt really good and she could drink a few more sips.

"Is this the ice cube made from those stones? magic."Sha Lan only felt that it was very magical.

The cat-eared girl drank several big sips in succession, and she felt very satisfied with each sip.

"This method of making is very simple and you can also make it yourself."Su Bai said softly.

In this hot weather, ice cubes are undoubtedly a 'life-saving' weapon. Many things are different with ice. Not only can you put ice cubes in tea, but also in fruits. Chill it

"I will make it every day in the future."Yu Ying responded without hesitation, her heart was about to get excited.

"Hahaha......"Su Bai put down the tea cup and said:"Actually, you don't need to make it every day. As long as the environment is suitable, it can be stored for a long time.""

"Wu, is it stored in the cellar?"Sha Lan immediately remembered that cellar.

"Well, after the cellar is built, you can make more ice cubes, store all the ice cubes there, and take them out when you want to use them."

Su Bai took another sip of ice tea and continued:"This way you don't have to make ice cubes every day, and you won't waste a lot of saltpeter."

Although there are a lot of saltpeter in caves, you can't squander it casually. You always have to prepare it for emergencies."

"I understand, I will ask them to build the cellar quickly so that we can store a lot of ice. Sha Lan said immediately.

The cat-eared girl has not yet come out of the shock of the ice cubes, and she keeps looking at the ice cubes curiously.

"Wu, if I remember correctly, were these stones used to make explosives before?"Yanhua always feels that these stones look familiar.

"You remember correctly, the ingredient in explosives also contains saltpeter, and I have a very good memory."Su Bai said with a smile.

He originally thought that only the cat-eared lady would remember it, but he didn't expect that the horned lady would also notice it.

"It's amazing. It's amazing. It can be used as a weapon and can be eaten."Yanhua was so shocked.

She didn't dare to underestimate these stones. She always felt that these stones were more powerful than witchcraft.

"This is the power of chemistry, and many things can be harnessed."Su Bai said gently.

Many times, a substance can produce different reactions when combined with various other substances.

Each reaction is not completely similar, but some are very different, just like saltpeter.

If If it is well made, it can also be used as a small firework, and it can also be used for viewing.

"You will definitely like this Cocoa, but I can’t learn it thoroughly anyway."Yanhua pouted.

It's not that she doesn't want to learn, it's just that she just stayed put no matter how much she studied some time ago. She doesn't learn as fast as the blond girl. Cocoa can easily get results once she starts researching.

Although some results may not necessarily be true. It is right, but after all, you are trying, and you will gradually find the right one.

"I don’t know what he cares about your sea fish tribe."Su Bai thought of the tribes by the sea.

"Yes, several days have passed. Nothing should happen, right?"Yanhua is also a little worried.

"Wu, do you want someone to take a look? This will also make you feel more at ease. Sha Lan suggested

"All the tribe’s hot air balloons have gone to the Haiyu Tribe. Let’s ask Shufeng and Ai’er who is free and let them take a look."Su Bai ordered.

At this time, he felt a little troubled by the lack of information circulation. He had no idea what was happening on the other side of the sea.

Even if there was a sudden attack over there, the Yanlong tribe had no idea at all. Not to mention sending people to assist.

It's not enough to rely on the tribe's three winged totem warriors alone, and it's inconvenient to convey the message.

"I’ll ask whoever is free later and ask them to visit the Sea Fish Tribe."Sha Lan nodded.

Indeed, the tribe's people have been going to the Haiyu Tribe for some time, and there has been no news back yet.

It will inevitably make people feel worried, even though there were totem warriors there before.

Now it is Eternal At the end of the night, all major tribes are eyeing other tribes.

Or those exiled tribes may launch attacks on the Sea Fish Tribe again.

"It seems that we have to prepare for the carrier pigeon." Su Bai said rigorously.

In fact, in ancient times on the earth, using pigeons to send messages was the most common method of transmitting information. Using pigeons to send messages would be faster and shorter than using people to send messages at high speed. Pigeons are mainly used to send messages.

People use the homing nature of carrier pigeons to carry messages, rather than returning to the nest for the purpose of delivering messages. Therefore, they can only bring letters back to the nest from outside, that is to say, take the pigeons out, release the pigeons when they want to send the message, and the pigeons return to the nest to carry the message. Pigeons do not go back to deliver messages. Just cultivate a group of pigeons in one place and take some with them when you leave.

In fact, there are many ways to describe pigeon positioning, such as magnetic field, vision, and even smell. Most of them are considered magnetic field positioning.

Good pigeons generally do not stay in strange places for a long time. Generally, pigeons only communicate one-way, that is, they take the pigeons out and send messages back home.

There are also two-way communication, such as resting at point A to build a nest, and eating at point B. They go to eat. Time is one direction, and when you go home, you are in the same direction.

This distance is not very far. Long distance communication can only be in one direction. In other words, they can only go home and send messages along the way.

You cannot tell them to go wherever you are told. Well, if you want to send messages in multiple directions, you can only raise more pigeons, each with its own route. Instead of one pigeon with multiple routes

"Wu, what is a homing pigeon? Sha Lan said doubtfully..........................................
