Eating the food, everyone began to speak freely, and the emotions that had been suppressed were obviously much better, and the lover threw a needle and led him to an idea.

"Fifth brother, if we are going around in circles, it must not be a straight line, so as long as we can think of a way to walk in a straight line, we should be able to leave here quickly. ”

"Brother Liang, the key is that you can't walk in a straight line, you can't see anything five meters away now, and you can't tell if you're walking in a straight line. ”

Wan Xiang munched on the chicken leg and complained vaguely, but there was no worry in that appearance.

Liang Liang pondered for a while, and suddenly said crisply: "Fifth brother, I have a way, but I don't dare to guarantee that I will be able to go to school."

"Oh? ”

"Fifth brother, in fact, two points can extend a straight line. ”

"Huh?" Liang Liang's sentence can be confused by the bottom of the first five, what two points? What extend the straight line?

Fortunately, Liang Liang didn't let Chu Wu be stunned for too long, so he continued: "We can use the rope to tie the rope to Sister Xirou's crossbow arrow first, and then let Sister Xirou shoot the crossbow arrow in one direction, the best crossbow arrow is based on the length of the rope, and estimate the downward tilt angle, so that the arrow can be shot into the ground, to avoid the reaction force with the rope when it falls short and change the direction at will." ”

What is the mushroom lid? When is the angle calculated according to the length?What is the reaction force?

I didn't expect Liang Liang's explanation to be even more confused on the fifth day of the first month, and then looked at the others, except for Shuhan, who was thoughtful, all of them were at a loss.

However, Chu Wu's face was as usual, and he seemed to be urging very clearly: "Well, yes, keep talking." ”

"Then we move along the shot rope, and when we reach the end of the rope, we use the visibility of five meters to mark two points, and then retract the rope, and let Sister Xirou stand on the point behind her, and shoot the crossbow arrow tied to the rope towards the point in front, so that we can basically get a continuous straight line, even if there is a deviation, it should not deviate much. ”

"Well, okay, this method is good, Xirou, do you understand?"

Xirou's brain was stirred into a mess by the cool words, and when she heard the question of the fifth year of junior high school, she replied blankly: "Huh?

Chu Wu shook his head, looking helpless, "Forget it, Liangliang, you can teach Xirou how to do it by hand, it's too complicated, I can't explain it to her in a sentence or two." ”

Seeing that he could solve problems for the fifth year of the junior high school, his cool eyes were full of happiness and joy, and he nodded: "Okay, but how long is the rope you brought, fifth brother?"

"One hundred meters, I deliberately brought more zeros, for fear of suddenly using them. ”

On the fifth day of the first month, he had a look of planning ahead and in control, but in fact, he didn't know what the cool way was, alas, the dignity of the leader of the team.

"One hundred meters is just right, not long or short, fifth brother, I also need you to get me two straight wooden sticks that are up to the height of Sister Xirou's chest. ”

"Straight sticks, what are you using?"

"Mark two points, to the straight wooden stick on Sister Xirou's chest, this height is the most convenient for Sister Xirou to shoot. ”

"Oh, yes, yes, it makes sense, I'll cut you straight sticks in a while, are you afraid that you won't be able to find a sticks in this wood, you can probably tell Xirou how to get it first, and then I'll eat it." ”

Although everyone didn't understand what Liang Liang was going to do, they knew that she had found a way to walk in a straight line, and this also clearly found a way out of this fog, and suddenly her morale was high, and Wan Xiang praised her excitedly.

"Oh mom, why does this cool girl's head grow, and she doesn't look much bigger than my head, why is she so smart, fifth brother, what is the cool girl going to do? ”

Chu Wu glared at Wan Xiang angrily, this is really a pot that can't be opened, so he mocked: "Just your head, no matter how big it is, it is also a rice bucket, this kind of method involving knowledge, you can't understand it, wait patiently and see." ”

The fifth junior high school knew that Liang Liang was very knowledgeable, but she really didn't expect that in such adversity, she could come up with such an ingenious way, and then Liang Liang instructed Xi Rou how to shoot, and then how to locate the two points, and then how to continue to shoot straight along the straight line shot before

Everyone was impressed by Liang Liang's wisdom, including the fifth year of junior high school, secretly sighed in their hearts, how lucky he was to make a strange woman like Liang Liang fall in love with him.

After advancing a little slowly for more than four hours, suddenly Xirou turned her head to look at the fifth year after shooting an arrow, and exclaimed in surprise: "The fifth day of the first month, this arrow missed, and I felt it from the pull of the rope." ”

Everyone was shocked, and after watching it for so long, they already understood the principle of Liangliang's method, so when they heard Xirou's arrow shoot into the air, there was only a downhill or cliff in front of them.

However, on the fifth day of the first month, he immediately thought of the magma crack in the state prison in front of him.

In any case, this was the first anomaly to shoot a crossbow arrow after four hours of advance, and the first five ordered to prepare for battle while cautiously driving the 'Maple Leaf' along the straightened rope.

When they reached the edge of the rope, everyone froze, and the fifth day of the first month did not guess wrong, the arrow did shoot into the magma crack, but there was only a crack here, but there was no magma.

Standing on the edge of the crack, there is no fog here, so that everyone can see clearly the scene in front of Ling Quanhan, this is a state prison, or it used to be a state prison, but the fog wall that originally protected the state prison in a hemispherical shape no longer exists at this time, exposing everything in this state prison.

It can probably be seen that this state prison used to be about six sections, because all the houses and canals and other facilities in it were there, but the grass turned gray, and the light curtain of the well was not there, and the well without "fireflies" looked no different from an ordinary well.

Chu Wu's heart was overwhelmed, because in his heart, the fog wall had always been an indestructible existence, and he said in a slightly trembling voice: "Let's go, let's go over and have a look." ”

There were only houses and tools left in the state prison, and there were no fields and food, and there were traces of human activity, but there was not even a single corpse

Now in front of the well of this state prison, he softly read the name of this state prison - "Xia State Prison".

The beloved, who had never been unfazed, was the most emotional at this time, and he asked to Chu Wu in a voice of extreme fear and worry: "Fifth brother, what happened to this Xiazhou Prison? Why did it become like this? What about the fog wall? Isn't the fog wall indestructible?"

A series of questions in fact, the fifth day of the first year also wants to know, although he wants to return to Longzhou Prison immediately at this time, but he must first calm down the feelings of his lover and the people.
