Everyone looked at each other and began to nod, and those who agreed to send the advance team began to nod in agreement.

More than ninety percent of the people in the room instantly agreed, and none of the people who disagreed objected.

Stan laughs and says, "So let's get ready to go, get dressed first." ”

The three of them began to get up to pick up their equipment, and when they picked up their chemical protection suits, they found a large box underneath.

When the three of them saw the box, they didn't put on their clothes and moved the box, and when it opened, it was a box of twelve large blue oxygen cylinders.

The back of a chemical protective suit can hold a bottle, and immediately the dean came over to take a closer look.

The dean looked at the note on the oxygen cylinder and explained: "It says 10L oxygen cylinder, and the theoretical use time is 600 minutes before the indicator light reaches the red range." ”

"600 minutes is 10 hours? So a bottle can hold five people? 12 bottles is 60 people. Another immediately explained.

"Your calculations are too one-sided, and you can't just do that. If you think about it, there is someone who wants to come back with a bottle, regardless of the weight of that person. Only four people can be sent away on one trip, but at least twelve hours of oxygen are consumed. Another said.

As soon as these words came out, the crowd began to count the number of people in the hall.

After the count, he shouted, "There are thirty-seven people in the hall, and there are thirty-three people after removing the four dead." ”

"There were thirty-three people in total, and there were twelve bottles of oxygen. Four people were sent away in one trip, and what was the result?"

Unable to get an answer, all the deans scratched their heads and were at a loss.

Having spent a few years in China, Harry now understands that mathematics is everyone's weakness. Harry held his fingers on the ground and began to draw the formula, and after a formula, Harry stood up and said: "It was said before that it takes twelve hours of oxygen to send four people away and one person to come back with two hours of oxygen, and if you put in the formula, then divide thirty-three people by four, and you will get all nine trips." Then nine trips for twelve hours of oxygen is one hundred and eight, and twelve bottles of oxygen are about one hundred and twenty hours. One hundred and twenty minus one hundred and eight, there is still twelve hours of oxygen left to waste. ”

Harry wiped the sweat from his head, the simple formula had already killed many of his own brain cells. And Harry would feel that there was something wrong with his arithmetic for a while, but it should be the same as this answer.

No one argued with whether Harry's algorithm was correct, and everyone nodded their heads when they saw Harry's algorithm.

Seeing that everyone was supporting, Harry realized that he shouldn't have said it. At this point, Harry looked at Stan and knew that everyone would not end well if they agreed. At this moment, it was too late to change his words, looking at the five huge oxygen cylinders, Harry said again: "No, no, I found a problem." If five people came back alone, how could one person carry five oxygen cylinders on his back?"

As soon as these words came out, everyone fell into confusion again, and the one who seemed to have the most strength among the three deans behind Stan tried to lift an oxygen cylinder and still be able to hold on.

The expression of holding the two bottles in his hand was extremely difficult, but at this time he no longer had the hand to pick up the third oxygen cylinder. What's more, it's too difficult to walk for an hour with one bottle on your back and two bottles.

Stan also panicked at the moment, looked at Harry and said, "What about five people going to two people back?"

Stan gives Harry a look that means finding a way to solve the problem.

As soon as the words were spoken, Harry was directly miserable. Harry continued to keep his head down on the ground and continue to do the math. After half of the calculation, he shook his head and said: "This is unreasonable, nine more trips for one more person will give you thirty-six hours of oxygen, and we only have eighteen hours." ”

As soon as these words came out, they all suppressed the confidence of the people in the hall, and Stan looked at Harry and whispered, "What are you doing? How can you say no?"

Harry shook his head in embarrassment and said, "You can't lie to people, if someone follows and can't get the answer?"

"You see that guy here seems to do the math?" Stan growls through gritted teeth.

Indeed, after Harry introduced the equation, everyone just waited blankly, and no one looked down to verify it.

As Stan gritted his teeth in resentment, the brawny man piled all four cylinders of oxygen on the floor. A man tried to push four cylindrical bottles, knocked on the bottles and said, "What are you doing with all this nonsense? Am I not pushing? It's a big deal to spend a little more time, it will definitely not take more than eighteen hours." ”

As soon as these words came out, everyone began to agree to the final plan, and the five of them went out. Then a man with clothes on his back and an oxygen cylinder pushed four back, and no one dared to stand up and refute it.

Stan looked at Harry and whispered, "Get dressed, I'll be the first to kill you." ”

After the matter is settled, the three behind Stan don their hazmat suits.

Chemical protective suits are all plus-size, not even plus-size. Because the person who wears it can show a large gap, but the relative person can't wear a chemical protective suit at all.

There must be someone else to help support and tie it tightly, and watch the three of them get dressed. Stan took one of his own and tossed one to Harry, and Stan said, "You can put it on for me." ”

Harry understands that Stan has a lot of contraband, and it wouldn't be good to let someone else get their hands on it if they find something.

With no choice but to help Stan put on his clothes, the two of them go to the side of the corner.

Stan pulls out a second dagger from his left foot, an angle that only Harry can see.

Sure enough, there was a second dagger, but Harry wondered why Stan pulled out the dagger and placed it in the right hand lining of his hazmat suit.

Harry helps Stan tighten his waist, but when he tries to lock his right hand, Stan whispers in his ear, "It doesn't need to be that tight, we don't go out." ”

It was said so quietly that only Harry could hear it.

"Not going out?" said Harry.

Stan readjusts his forehead band, and Harry looks at Stan in confusion.

Stan then whispered, "Just do it, and I'll climb first, and you'll have to be the second." ”

Harry helps Stan get dressed, then takes his hazmat suit and asks the other deans to help him get dressed.

After putting it on, it was stuffy and suffocating until someone helped insert an oxygen cylinder and connect it to the tube.

After breathing well, Harry tried to take two steps, which were a little difficult to walk but acceptable.

Stan walks over to the side of the iron ladder, gets up to it, and begins to climb upwards.

Harry looked at Stan and remembered that he had to be second if he said he would climb first.
