"Poof!poof!poof......"

As the bronze spear continued to stab, a palm-sized poisonous spider was poked into a ball of meat sauce in the blink of an eye.

"It's just a reptile, how could I be afraid!"

Seeing this, Feng took back the bronze spear in his hand and said loudly.

The highly poisonous spider in front of him was not the first poisonous insect killed by Feng.

Before, after being ridiculed by everyone, Feng killed insects when he saw them in order to prove that he was not afraid of poisonous insects.

Along the way, several poisonous insects have already been brutally killed by him.

Moreover, the death is as miserable as this spider, and all of them have been poked so that they can't see what they look like.

And Feng's behavior of wanting to cover up obviously failed to clear his name.

However, Lin Luo could also understand that Feng was not really afraid of poisonous insects, but simply psychological disgust.

It's like a mental illness like a phobia and a fear of heights.

After all, most of the poisonous insects are hideous and disgusting.

As for the others, they just smiled and didn't say anything.

This matter is only Feng alone.

......

"It's here!"

Soon, Lin Luo led everyone to the true destination of this trip.

But looking at the scene in front of them, everyone was stunned.

"Well, how can there be potatoes here?"

Yong immediately turned his head to Lin Luo and asked.

At this moment, what appeared in front of them was a large potato field.

For potatoes, this crop is still relatively familiar to everyone, and they can recognize it at a glance.

After all, within the tribal union, potatoes have been grown for several years.

"This was formerly the residence of the Plover tribe. ”

Hearing Yong's inquiry, Lin Luo replied aloud: "The potatoes I brought back back were obtained from here. ”

"That's it!"

Hearing this, Yong showed a clear expression.

But then, he asked Lin Luo with a puzzled face: "Lin Luo, didn't you say before that this time you were looking for materials to use with lime?"

Why did you go to the dwelling place of the Duck tribe and dig potatoes?"

"The ingredient I'm talking about is this potato. ”

Lin Luo smiled directly and pointed to the potato plant in front of him.

"Potatoes?"

Hearing Lin Luo's words, not only Yong, but the rest of the team also suddenly showed a stunned look.

In their minds, potatoes are just food, and when baked, they taste soft and glutinous, and they taste very good.

Never thought about it? Potatoes can even be used to build a city.

"Okay? Don't waste time, dig it up!"

Lin Luo didn't explain much? Said directly to the crowd.

"Yes. ”

Heard? Although everyone's hearts were full of doubts, they nodded in response.

Subsequently? He immediately stooped down and dug up.

Soon, fist-sized potatoes? They were dug out of the dirt one after another.

Is it summer season now? After a full season of growth, these potatoes are ripe at this time.

Lin Luo bent down to pick up a potato and gently wiped the soil on it, and couldn't help but smile on his face.

What did he just say? Want to use potatoes with lime as a binder? But it's not a lie.

In ancient China, lime was used as a building material for bonding for a long time.

In order to achieve a better bonding effect, in addition to adding sand and a small amount of clay to it, glutinous rice water is also added.

Organic starch in water through glutinous rice? Mixed with inorganic lime, a dense microstructure can be formed.

Thereby? Let it have stronger strength and toughness, and exert a better adhesive effect.

One of them? Sand and clay are not a problem.

After a major flood that caused the course of the river to change? Is there a long stretch of river that has dried up? A large amount of river sand was exposed.

So? They don't need to worry about the sand at all.

As for clay, that's not to mention, it's more readily available than sand.

The only thing that worries Lin Luo is the glutinous rice water that cannot be missing.

Although the tribal alliance now has white grain, the effect that white grain can play is undoubtedly far worse than glutinous rice.

What's more, with the amount of White Valley that the tribal alliance has stored now, it is far from enough to build a city.

It is also even more impossible for them to wait for the He clan to plant more white grain before starting to build the city.

Therefore, after thinking about it for a while, Lin Luo quickly thought of a substitute.

That's right!

The main reason why glutinous rice water can have a good bonding effect is because it contains a large amount of amylopectin in glutinous rice.

To put it bluntly, it is only amylopectin that plays the role of bonding.

In addition to amylose, potatoes also contain a large amount of amylopectin.

Using potatoes instead of glutinous rice can be said to be no problem at all.

However, it was a bit cumbersome to explain about amylopectin, and they didn't understand it at all.

Therefore, when Yong asked just now, Lin Luo didn't bother to explain.

"Poof!"

While everyone was digging, Lin Luo threw the potatoes in his hand to the ground and walked forward.

In the deepest part of the valley, except for the reddish-brown chestnut trees, there is still no grass.

In the canopy of those red chestnut trees, there were many nests of birds, large and small, but now there is no one to be seen.

It should have been completely washed away in that great flood.

Soon, Lin Luo moved his gaze and looked at the thickest and tallest red chestnut tree that needed to be surrounded by several people.

On that giant chestnut tree, the giant nest where the bird spirit lived, was quite well preserved.

It was not destroyed by the flood like other dens.

It's a pity that the bird spirit that originally lived in it is no longer there.

Looking at this scene, Lin Luo couldn't help but think of Wuteng.

At the beginning, it was because of the rescue of Wuteng that he first came into contact with the Duck Tribe.

Later, when he went with Uto to collect the juice of the violet flowers, he found potatoes called white sunflowers by the Otto tribe.

Before leaving, he also gave the pure copper dagger he had traded from the Zhijin tribe to Uteng.

Now, after nearly four years, he has returned here, but it is already a thing or a person!

"I don't know if Utou is still alive now. ”

Thinking of this, Lin Luo couldn't help but whisper to himself with embarrassment.

......

An hour later,

"Is it all ready?"

Lin Luo turned his head to Yong and asked.

"Hmm. ”

Yong immediately nodded and said, "The animal skin packages I brought are all full." ”

Hearing this, Lin Luo glanced at it and saw that at this moment, all the totem warriors were carrying hundreds of catties of animal skin packages on their backs.

This time, the reason why Lin Luo brought all the totem warriors was because they had enough strength to be able to carry more potatoes.

This is incomparable to ordinary warriors.

Soon, Lin Luo turned his head to look at the potato plants not far away.

After three years of desertion in the valley, the area of potatoes that used to grow here has now multiplied at least tenfold.

Naturally, they can't take them all with them on this trip.

If you save a little, it should be enough to build a city wall!

Looking at the remaining large slices of potatoes, Lin Luo secretly thought in his heart.

"Let's go!"

Soon, he also carried the huge animal skin package beside him, and gave the order to return.

PS: Regarding the use of potatoes instead of glutinous rice, it is purely personal speculation, and please don't take it seriously, after all, it's just that!
