What should I do if I accidentally come to the ancient times?

So, how much bamboo does this cofferdam need?

Zhao Hao made a rough estimate, and then retreated a bit.

Because the cofferdam needs too much bamboo, the visual width of the big river in front of us is at least 50 meters, and for the convenience of knocking the bamboo into the bottom of the water, its thickness cannot exceed the arm of an ordinary person.

That is to say, the diameter of the bamboo should be about five centimeters. According to the structure of the cofferdam, a river with a width of 50 meters needs at least [-] bamboos!

What is the concept of cutting five thousand bamboos?

If you use a stone knife, I'm afraid you won't be able to cut it all in a month!

Of course, Zhao Hao could also choose to use magic weapons. With the sharpness of magic weapons, he might be able to cut down five thousand bamboos in half a day.

The problem is, he doesn't want to destroy the magic weapon!

You know, bamboo is notoriously tough. Ordinary steel knives can't cut at all. Even with the best quality steel knives, if you cut a few bamboos, there will be at least a few gaps the size of rice grains. , If you cut hundreds of bamboos, even the best steel knife will be useless, let alone thousands of bamboos.

Zhao Hao really didn't want to destroy the magic weapon, but he couldn't think of a better way.

In the end, he chose to try first.

That is to use the magic weapon to try cutting a few bamboos first. If there is a gap in the magic weapon, he will give up this plan and find another way.

So, he directly chose a bamboo forest with a relatively suitable size and started testing.

With a brush and a knife, a bamboo as thick as an arm snapped off, and the branches and leaves fell down with a clatter.

Seeing this, Menglan and Mengbao who were not far away immediately ran over, sat on the fallen bamboo, and slapped each other.

They are pulling bamboo leaves.

Iron-eating beasts have a habit of eating bamboo leaves, that is, they like to roll off the bamboo leaves, make a large handful, and then stuff them into their mouths to chew. In this way, after a few mouthfuls, dozens or even hundreds of bamboo leaves will enter. The stomach is full, and I don’t know how many times faster than eating one piece at a time.

They love to eat bamboo shoots, but they also love to eat bamboo leaves. For them, eating bamboo shoots and then eating bamboo leaves, and then eating bamboo shoots and then eating bamboo leaves, is a rare enjoyment for them.

Zhao Hao couldn't help crying and laughing when he saw their intoxicated faces.

I'm just testing a knife, okay? Why are you two running over to join in the fun?

He brought the magic soldier closer to his eyes, and fortunately, there was no gap on it.

However, cutting a bamboo without a gap does not mean that there will be no gaps when cutting a bunch of bamboos. Moreover, the possibility of such gaps seems to have nothing to do with the speed of cutting bamboos. That is to say, if you chop ten bamboos in 10 minutes Bamboo is basically the same as cutting ten bamboos in ten seconds.

Thinking of this, he simply gritted his teeth, brushed and chopped, and didn't stop until he had cut ten roots.

It's broken, and the edge of the magic weapon has clearly shown a slight wave shape, which is a sign that the gap is about to burst.

That is to say, if he cuts a few more, there will be a gap in the magic weapon.

It seems that the method of cutting with magic weapons will not work!

First of all, this rare magic weapon will definitely be scrapped, and more importantly, even if he destroys the magic weapon, he will not be able to cut down five thousand bamboos.

Calculated according to the transformation speed of the magic weapon, he estimated that after cutting about a thousand pieces, the magic weapon will turn into a saw blade!

Alas, the experiment failed unexpectedly, and the blade of the magic weapon became obviously wavy, which is not worth the candle!

Just when he was very annoyed, something miraculous happened suddenly, the wave shape on the magic weapon was slowly returning to its original shape at a speed visible to the naked eye.

After a while, the magic weapon became smooth as new, as if it hadn't been deformed!

This, this, this!

How is this going?

Could it be that the magic weapon is made of memory alloy?

This sharp blade can be memorized, never heard of it!

He gritted his teeth, chopped down another ten bamboos, and then brought the magic soldier to his eyes to observe carefully.

In the end, it was still the same, there was a slight wave on the Divine Weapon, but this slight wave soon began to slowly return to its original shape!

This thing is really made of memory alloy!

The blade can remember, what a high technology!

Could it be that this divine weapon was really created by the gods?

Chapter 22 Cofferdam Fishing

Zhao Hao did not think that the magic weapon has memory function. However, he has no time to study the magic weapon at this time. As winter is approaching, the time left for him is getting less and less. Just get up.

Ever since, he brandished the divine weapon and started chopping bamboo.

Although the divine weapon has a memory function, he still didn't dare to use it too violently, and he didn't dare to gamble on whether the divine weapon could return to its original shape after a gap appeared.

Therefore, every time ten bamboos were cut down, he would ask Grandma and the others to drag the bamboos away to deal with the branches, and continue cutting after the magic soldier returned to its original state.

In this way, although the speed is slower, it can ensure that the magic weapon is not damaged, and it is worthwhile to spend a little more time.

It took him half a day to cut down [-] bamboos. Next, he led everyone to remove the branches, go into the water to measure the length, and sharpen the bottom to insert into the sand at the bottom of the river. In the village, they were so busy that they didn't manage to deal with the chopped bamboo until dusk fell.

However, they didn't have to turn around this time, because Grandma brought two pieces of smoked wild pork, which weighed more than 30 catties, which was enough for them to have a full meal.

This can be regarded as Zhao Hao's benefit to everyone. After all, there is not much meat left from the wild boar king at the moment. Adding it all together, it is enough for grandma and the others to eat for a few days. After eating these, they have to Find a way to hunt other beasts.

Although they brought meat, they did not bring fire, because Zhao Hao thought it was too troublesome, and it was just lighting a fire. For others, it might be an extremely difficult thing, but for him, it was a simple and impossible task. It couldn't be easier.

He knows at least a dozen ways to start a fire. Although the principle is similar, they all use friction to start a fire, but each has its own secrets.

For example, to light a fire in this bamboo forest, two pieces of dry bamboo are enough.

This is the most indispensable thing in the bamboo forest. He has ordered people to prepare a lot of dead bamboos that have been broken due to various reasons.

So, how do you start a fire?

It's very simple, he directly picked the driest bamboo, took a section about one meter long, split it in two, and then scraped off a pile of thin bamboo chips on the surface of one of them with magic weapons He thought it was tinder, and next, he cut a groove in the middle of one of the outer circles until it was slightly penetrated, and when a small hole was cut, the preparation work was considered complete.

Next, he directly erected another piece of bamboo and supported it with his chest. Then, he picked up the cut piece, and stuck the cut groove to the side edge of the other piece, and placed it above the cut hole. He added a piece of tinder to hold it with his hands, and then he began to rub up and down rapidly.

After a while, thick smoke came out from the middle of the tinder, and he carefully poured out the tinder to see that there was indeed a little spark in the middle.

At this point, it’s basically the same, just lift the tinder, blow lightly on the spark a few times, and with a coaxing sound, the tinder will be on fire.

The whole process took him less than 5 minutes in total, and the speed was simply indescribable.
