Traveling through ancient times: Savages are hungry for food

Sang Tian thought it was some kind of animal, but it turned out to be two falcon cubs.

The hair on its body hasn't grown fully yet, so it probably just hatched not long ago.

The sudden flutter was probably because he smelled something like Sang Tian's bones lying on the ground.

I was so hungry that I did this.

It seems that the Zhuyu flower really has a great impact on birds.

Their eyesight seems to be completely gone now, and their wings have lost the ability to flap.

It relied entirely on its hunting instinct to struggle over, following the smell.

Sang Tian couldn't bear it.

"When you leave, take them with you and release them when they are better."

Then Jie and Sen each picked up one and returned to the Falcon Tribe to feed the two little guys some water and food.

……

Everyone set off again.

At this time, the team was getting bigger and bigger.

The group was chattering on the road, it was very lively.

Half a day later, they passed by the stone pillar where the hawk was perched.

Sang Tian could clearly feel that the temperature was getting higher the further they went in this direction.

This place is getting drier and drier, and even the ground has cracks.

The surrounding plants, especially large trees, gradually decreased, and it was obvious that anti-inflammatory plants grew exceptionally well.

Moreover, Sang Tian saw the changes in the environment along the way.

Then I realized that it wasn't a stuffy nose caused by a cold.

But there is a faint obstruction in the air.

What gas molecules are flowing in the air?

Sang Tian felt increasingly anxious and uneasy.

From a distance, it looks tall and slender.

It was not until I got close to it that I realized that this "stone pillar" was 30 meters in diameter!

The "stone pillar" has been eroded by wind and water for a long time.

Therefore, the surface is layered and bumpy, similar to karst landforms.

However, Sang Tian discovered some unusual substances on these stone pillars!

There is some substance on the surface of the rock, and the surface looks ancient and grayish in color.

But when Sang Tian peeled off the skin.

Inside is a colorless and transparent crystal, like a crystal gem, pure and translucent, and you can clearly see the light refracting in it.

However, due to the inevitable presence of impurities in the natural environment, it may also have tones such as light yellow and light gray.

Some of this substance is long and sharp, like tiny silver needles gathered together; some are like fine silk threads, intertwined with each other; some are a thin shell attached to the surface of objects; and some are distributed in the form of small particles.

These things should be formed by the erosion and evaporation of rainwater.

Sang Tian looked at the substance carefully.

A pair of curved eyebrows were furrowed in wrinkles.

Trying hard to search for the knowledge that I have learned in my mind.

But she wasn't sure, as she had only read about it in a book and had never thoroughly understood it.

The system can only detect plants and animals, and has no way to detect dead objects.

In an instant, an idea flashed in Sang Tian's mind!

A confident smile appeared on the corner of his mouth.

There is another way to confirm whether this is what she thinks!

"Are there any caves around here?"

The bird of prey from the Falcon Tribe said without hesitation.

"There's one not far from here, it's quite big, but the cave is weird..."

"What's weird?"

"It's just... there's a faint white glow in that cave... it's so weird.

So normally the tribesmen won’t go there.”

Sang Tian's eyes suddenly sparkled with excitement, like the brightest stars in the night sky. Her hands unconsciously clenched.

The volume suddenly increased by more than one degree!

"Take me there quickly!"

The bird of prey saw how eager the female was.

So he took everyone there.

I saw that it was a cave hidden in the rattan curtain.

After everyone lifted the vines and went in, a faint white light flickered in the cave.

Sang Tian touched it.

It is almost certain that this is saltpeter!

Natural saltpeter is often found in caves, where the relatively stable temperature and humidity provide favorable conditions for its formation and preservation.

The stone walls of the cave are sometimes covered with a layer of white saltpeter, which glimmers in the dim light.

This is why Sang Tian asked Ying if there was a cave here!

Saltpeter is also known as flame saltpeter, potassium saltpeter, etc.

It makes gunpowder!

Saltpeter is a key ingredient in gunpowder and is primarily used in the military to manufacture guns, ammunition, and other weapons, changing the landscape of warfare.

However, Sang Tian thought.

I will definitely go through many trials, control the proportions, and successfully make gunpowder.

Even though this process is not very safe and requires a lot of energy and time.

But Sang Tian may not use it in the future.

It is made to ensure the bottom line safety of oneself or one's tribe.

But, as long as it is not a real life and death situation.

Sang Tian might never take it out again.

Hot weapons are not what should appear in this era...

Of course, it can also be used to make fireworks, adding brilliant colors to the festival.

In addition, saltpeter can be used as a clarifier in the glassmaking process.

Saltpeter can also be used as a preservative in the food industry, but its usage is strictly controlled.

But what makes Sang Tian even more jealous is, of course, making cold drinks!

When saltpeter dissolves in water, it absorbs a large amount of heat, lowering the solution's temperature. When saltpeter is dissolved in water, the surrounding water freezes into ice due to the low temperature, thus achieving artificial ice production.

Summer is not far away, and it will be a good time to escape the heat.

It makes me happy just thinking about it, being able to drink iced drinks in this ancient wilderness.

This is so lifelike.

……

Jay asked with a grin.

"What's this? Sister Sang, why are you so happy?"

Sang Tian smiled but said nothing.

"What if I told you I could let you see ice during the hot and dry summer?"

Jay glared.

"Haha, how is that possible? Stop teasing me!"

Sang Tian didn't explain any further.

He simply cut off a piece of saltpeter and threw it into his kettle.

Shake vigorously to mix well.

After a while, he handed the kettle to Jay.

Jay reached out and took it without any preparation.

But I was caught off guard and was actually frozen by the kettle.

The fingers shrank suddenly.

"Really? Really frozen?"

"It wasn't that fast. It was just that the temperature dropped very quickly."

"Oh my goodness, this is the Wolf God. This is so weird!"

So everyone passed the kettle around and tried it out.

Sure enough, I could feel the water inside the kettle was icy cold!

“It’s amazing!”

"It's so warm now! How can such a stone actually freeze?"

"Then we can have something so cool even in the hot summer!"

Sang Tian smiled and said.

"That's right, Ice Dog. We can fill a big bucket and store it in the house."

You can also use it to make cool drinks to beat the heat.

You are in for a treat! "

Everyone's eyes lit up.

The heat during the dry season is so intense that it's unbearable to think about it.

People who feel hot wherever they are are like ants on a hot pot, feeling anxious and irritable.

If only I could put a basin of ice and a bowl of ice drink where I sleep!

That would be so enjoyable!

The people of the newly recovered tribes were completely shocked by this petite and delicate female.

How can she be so smart!

The wisdom and insight she possesses are beyond imagination.

There really is such a perfect existence.

Jay stomped his feet immediately!

"Brother Cang is so lucky!"

……

Everyone marked a location.

So they continued on their journey.

The last stop, the Rising Sun Tribe!

After you finish this job, you can go home!

This time was the longest time Sang Tian had been out since she traveled through time.

You know what, I miss home a lot.

I guess Tianlang must be busy building houses every day now!

I really want to go back and see it soon.

And Zhuangzhuang, this little guy should be fat and plump because of the rain now!
