The blizzard lasted for more than half an hour and then began to gradually become smaller.

This snowfall is so disturbing.

Because the environment is still very bad.

Li Min is full of uncertainty about the way forward.

Finally, the snow stopped and the whole world became white.

Every place was covered with white snow, and everything on the ground was shapeless.

White flowers are scattered in the wind. The breeze blows, and from time to time there are large flakes of snow flying in the air, twinkling.

The trees were covered with snow, with layers of thick snow covering them, and the small branches on the sides were completely weighed down by the snow.

Everything around was covered with a thick layer of white snow, which gradually drifted away on the earth.

The sky gradually brightened up, and the sunlight shone through the gaps in the clouds and penetrated into everyone's heart.

At this time, everyone's hearts were filled with warmth.

And the thick white snow flutters into people's cheeks from time to time, and the cold feeling makes it difficult to breathe. A thick layer of white snow on the hills in the distance seems to have whitened the paint and washed nature innocently.

There is a real problem now, that is, the current situation is not optimistic.

A large amount of snow accumulated on the road ahead of the convoy, making the entire road more and more difficult to walk.

But fortunately, the visibility has become extremely high, so some unnecessary dangers can be avoided.

This is good news for Li Min.

Apparently his luck wasn't too bad.

Then Li Min gave the order.

Get everyone ready to go.

In fact, we are still some distance away from our destination.

But when everyone set out with high expectations, they encountered a problem.

When the car travels a distance of about 1km.

Suddenly, we were blocked by a river. The river was completely covered with ice. It was so thick that we didn’t know how thick the ice was.

At this time, the team did not dare to act rashly.

Because no one knows whether the ice of this river can bear the weight of the chariot.

If it cannot bear the weight of the chariot, everyone may fall into the glacier.

In this environment, if you fall into the glacier, it will be a test for your life.

What's worse, lives will be lost.

This is a severe test for everyone. But how can we pass this ice surface?

The problem came to Li Min again.

He convened everyone for discussion. At this time, Di Renjie first said: "Sir, it's better for us to cross the river first. As for the chariots, we will cross the river later to reach our destination. You also know that the distance is not too far."

This is a very good plan.

Others agreed.

But Li Min said: "The disadvantage is that the road ahead is long and the dangers are unknown. If someone is in danger because of this, what should we do?"

Indeed, it is extremely cold weather at this time, and the temperature outside has reached below minus 50 degrees. If you can be exposed to this weather for too long, you may die here.

What's more, you will encounter some ferocious wild animals.

If that's the case, what should we do?

Can they fight them off?

What if there were more of them?

Obviously, this won't work.

Therefore, Li Min's worries are not unreasonable.

"Then what should we do? Should we forcefully cross the river?"

Di Renjie asked again.

At this time, Li Min thought for a while and then said: "You can't force it! I have this idea. But I need more support. Does anyone among you know how to test the thickness of the ice surface? Is anyone able to measure the thickness of this ice? The thickness of the surface?”

Li Min said this.

At this time someone stood up.

"I can! I grew up in the north. We often encounter severe cold in winter there. And when it gets severe, the ice will freeze. Sometimes the thickness of the ice can even reach more than a foot! "

"Okay, go and test the thickness of the ice near here. Give me a detailed report and bring a few more people with you."

"Yes! Sir!" The man took several people with him to measure the thickness of the ice surface.

The reason why Li Min did this is very simple.

Then let someone calculate how thick the ice is needed for the chariot to cross the ice.

If it's too thin, it won't go through.

Think of another way.

If it can pass when it reaches a certain thickness, then they will pass!

"Sir, the purpose of doing this is to confirm whether you can pass?" Di Renjie said.

"Yes, that's the case. If it can be passed, only one person is allowed on each chariot, and no more than two people are allowed on it."

Li Min said this to ensure everyone's safety, because if the chariot had an accident and fell into the river, more people would be sacrificed. If there is only one driver on it, then everyone will do nothing to him. Rescue is also relatively easy.

That's why Li Min said this, and everyone understood.

"Oh I see!"

"Okay, Di Renjie, you are responsible for coordinating it and asking them to measure quickly! Tell me the results after the measurement comes back!"

"Yes, sir!" Di Renjie then ran to coordinate.

As for those people just now carrying tools.

Went down to the ice to measure.

But Li Min has more important things to do.

That was to find out some principles, so he picked up the phone and dialed a number.

And gave him a question.

If a chariot weighs 10 tons and wants to pass through a river full of ice, what is the minimum thickness of the ice for the chariot to pass smoothly?

Li Min also told him the contact area between the wheels on the chariot and the ground.

Next, he was waiting there.

About five minutes later.

The call came.

"what's the result?"

"Sir, the results are out."

Soon Li Min got the result.

Fortunately, the width of this river is not very wide. The widest is only fifty meters, and the narrowest is only about five meters.

"Tell me, what's the result?"

"The result is that the thickness of the ice surface must be greater than one meter to safely pass through. If it is a crawler, as long as it does not damage the ice surface, 60 centimeters is fine! Because the contact area is larger, the pressure on the unit ice surface is smaller!

"

"Okay, I get it!"

At this time, Li Min was not feeling well.

Because the next measurement of the thickness of the ice surface will rarely be as thick as thirty or fifty centimeters.

If this was the case, the chariot might not be able to pass, but it was not impossible. He was thinking that there must be other ways to pass.

But we still have to wait for the person's measurement results to come back before we can finally make a decision. If it's larger than one meter, then he can go directly. If it's smaller than this number, he has to think about it carefully.

After waiting for about half an hour, Di Renjie informed Li Min of the test results.

"Sir, the thickness of this ice surface is only between 30 and 50cm, and the thickest part may exceed 60cm! But it's still very little."

When Li Min heard this, he knew that it was impossible to pass.

So, he said: "Okay, I get it!"

At this time Di Renjie asked: "Can we pass?"
