Because the indoor temperature is much higher than outside, after walking for less than two minutes, Chen Dong felt hot sweat soaked on his back. Song Qiaoqiao simply started to beat his feet and put two torn pieces of wool sweater cloth into his pocket.

The corridor is lined with ordinary stone walls, without any decorations or murals on it, which looks extremely monotonous. From the outside, seeing such a huge building, to the not-so-spacious space after entering the door, it makes people feel a sense of visual disorder.

After walking for a few more minutes, the corridor finally came to an end. Chen Dong took the lead and his vision immediately became widened.

Outside the corridor, there is a place similar to the hall square, with brilliant lights, but there is not a single figure inside, making it look extremely empty.

However, before Chen Dong could see what was wrong with the hall, he was shocked by the scene in front of him.

In front of the hall, from left to right, twelve holes of the same size are neatly arranged!

Seeing this, Chen Dong couldn't help frowning. He walked forward, picked a hole, looked inside for a while, but found that it was dark inside and could not see anything clearly.

After repeating this twelve times, Chen Dong carefully observed each hole and found that each hole was similar. There was a metal door frame embedded on the hole. The space inside could roughly accommodate three people in parallel, but without exception, it was pitch black inside, making people unable to peek.

"What should I do now?"

Song Qiaoqiao did not notice that since she walked with Chen Dong, she gradually became accustomed to Chen Dong to make decisions, but she herself was too lazy to think and make judgments.

"It seems that Luo Sha's intention should be to divert the traffic." Chen Dong concluded.

Judging from the arrangement of these twelve cave entrances, this is obviously Luo Sha’s trick. No matter how many people walk together, when they arrive at this place, the best way is to act separately and break up the crowd.

Think about it, for twelve different choices, everyone's opinions must be different. No one knows what the situation behind each hole is like, and no one knows which choice is correct. Once the differences arise and each goes their own way, it becomes an inevitable situation.

Moreover, even if everyone wants to act uniformly, in terms of the width inside, there will definitely be three people walking in front. When encountering critical situations, even retreating will be affected by the companions behind you. Therefore, choosing a hole with a three-person unit is the best choice.

"What is your lucky number?" Chen Dong suddenly turned around and looked at Song Qiaoqiao.

Song Qiaoqiao was stunned and replied: "Hey... Jiu... you won't..."

Chen Dong smiled, grabbed Song Qiaoqiao's arm, and walked straight towards the ninth hole.

"It's too casual to choose like this!" Song Qiaoqiao looked helpless.

Chen Dong rolled his eyes and said, "What else would you do? In my opinion, you should be able to walk out of every hole. It's nothing more than the design of the process in the middle."

Song Qiaoqiao had nothing to say, so she had to let Chen Dong pull her into the darkness in the hole.

With the lights in the hall, Chen Dong could still see the road in front of him at the beginning, but as they continued to deepen, the light around him became dimmer and soon the two of them fell into complete darkness.

Because they could not see things, Chen Dong could only hold Song Qiaoqiao with one hand and touch the stone wall beside him with the other hand, and move forward slowly. Fortunately, their eyes soon lit up again.

After the two of them saw clearly what was happening in front of them, their faces became strange.

Chen Dong collapsed: "Is this the legendary..."

"Go up to the mountain of swords and down to the sea of ​​fire." Song Qiaoqiao added.

In front of Chen Dong and Song Qiaoqiao, countless sharp knives were standing with cold light, and dozens of flame guns, constantly spitting out the scorching fire dragon.

"Is this a dead end?" Song Qiaoqiao was a little confused.

Chen Dong sighed and said, "It shouldn't be, maybe we have to find a way to get around!"

After saying that, Chen Dong began to carefully observe this "sea of ​​swords and fire". The handles of the steel swords were all buried underground. He could only see the swords standing up, with blades on both sides, and cold air was rising. At first glance, it seemed to be arranged in a mess, but there were traces to follow.

Moreover, there are certain gaps between each steel knife, both large and small, and the large ones are enough for one person to pass through. I think it would be easy to be careful if you just pass through the knife forest.

The key is that the flame gun installed on the wall covers almost all the space on the tip of the knife. If you are not careful, it will cause fire to burn yourself. If the flames are burned, your feet will be disrupted. In a panic, you will inevitably hit the blade next to you, causing a cycle of evil surnames.

In this way, you will never be able to get out of this sword forest, and you will even be buried in it if you are not careful!

Chen Dong saw the sinisterness of this mechanism, so he focused on the flame gun, and then he discovered one of the keys.

The flame spray guns embedded on the stone walls on both sides do not continue to spit fire, but will have a brief pause after a period of time. However, the pause time of each flame gun is different, and there are subtle differences, so it seems that the flame in it seems that it has never stopped.

After making this discovery, Chen Dong began to calculate the frequency and angle of each flame gun, plus the route that the knife forest on the ground can be passed by, and comprehensively judged it, hoping to find a way to pass here.

Such a calculation is undoubtedly extremely large and complex. Song Qiaoqiao did not dare to disturb Chen Dong. She walked aside and tried to find out the loopholes, but soon she felt a headache and retreated.

"Impossible, no matter how you look at it, it's impossible!" Song Qiaoqiao frowned.

Chen Dong, who was standing beside him, was still motionless like a sculpture, his eyes became brighter and brighter under the reflection of the flames, and the sweat on his forehead became denser and denser.

Ten minutes later, Chen Dong rubbed his eyes that had already begun to swell, turned around and smiled and said to Song Qiaoqiao: "It's OK, come with me."

Song Qiaoqiao widened her eyes and said in surprise: "Have you really found it?"

"It should be about the same, time is tight, and some places may be a bit off, but as long as you are careful, you can still walk through it."

As he said that, Chen Dong pulled Song Qiaoqiao's hand and finally instructed: "I'll listen to my orders later and follow me!"

Song Qiaoqiao nodded. At this time, she chose to believe Chen Dong.

Chen Dong walked to the knife forest, looked up at the flame spray gun above, and silently planned in his heart, while taking a deep breath of heat.

"Walk!"

Suddenly, Chen Dong shouted and jumped forward. Song Qiaoqiao reacted quickly and almost at the same time followed Chen Dong's footsteps.

I saw Chen Dong stopping and stopping. Wherever he went, the flame spray gun on the wall was just extinguished, allowing the two of them to pass through calmly.

"bend over!"

"Half a step back!"

"Two o'clock direction, three two one, jump!"

...

Under Chen Dong's continuous command, Song Qiaoqiao followed closely behind and did not make any mistakes.

The only most dangerous time was that Chen Dong's right leg was accidentally cut by a knife, which made Chen Dong's footsteps unable to help but pause for a second. In this second, the flame spray gun that had already been extinguished speared out a pillar of fire again, which almost burned Chen Dong's face.

Fortunately, Song Qiaoqiao reacted quickly and reached out to pull Chen Dong's body that had already been poked out. Even so, Chen Dong was burned with several eyebrows.

In each step next, Chen Dong was more cautious and did not make any mistakes. After the two finally walked through the "sky sea of ​​fire", they couldn't help but breathe a lot, especially Chen Dong, who was always in a highly nervous and overloaded operation. Once they relaxed, they immediately felt a split headache.

"I finally came over!" Chen Dong sighed, looked back at the blockbuster fire with lingering fear, and finally realized what dancing on the tip of a knife is.

Chen Dong pulled away the ski jacket, revealing the tight muscles inside. After just a few minutes just now, Chen Dong was already wet, and beads of sweat kept dripping along the lines of his muscles.

"Let's go." Chen Dong wiped his face and led Song Qiaoqiao to continue walking forward.

The next section of the road was relatively calm. Just when Chen Dong thought the test had ended, they came to a slender corridor.

The corridor was only accessible to one person, with suspicious and familiar rubber sticks on both sides.

"This won't be..." Chen Dong smiled bitterly and took a step forward.

Sure enough, just as Chen Dong stepped into the corridor, the rubber sticks on both sides of the corridor began to wave wildly, forming a completely airtight black.

Chen Dong suddenly heard the sound of Luo Sha once said that the ability to fight against strikes is a compulsory course for them, so it seems that such a level is not difficult to understand.

"It seems that I can only break through?" Song Qiaoqiao also saw the role of this corridor and felt a little deeper.

Chen Dong sighed helplessly: "Then let's break through!"

After saying that, Chen Dong kicked his feet and rushed forward suddenly. Because there was only one way, there was no need to distinguish the direction. Chen Dong protected his head with both hands and lowered his head and ran quickly.

"Bang!"

"Bang!"

...

The rubber stick fell ruthlessly on all parts of Chen Dong's body, making a series of muffled sounds. Chen Dong seemed to have returned to the first day of his arrival at the training camp, facing an inhumane welcome ceremony.

But the difference is that Chen Dong is now more than a little stronger than that time.

Chen Dong dared not stop at all, and almost burst out his greatest potential to rush forward. At this time, staying for one more second will lead to another second, and there are sticks on the top, bottom, left and right, and there is no place to dodge.

Suddenly, Chen Dong felt a stick in cold calves, and he staggered and almost fell to the ground. But he did not dare to fall, nor could he fall. Chen Dong stretched out his hand and grabbed the rubber stick that was waving frantically beside him, stabilized his body, stayed there for two seconds, and then ran forward again.

This time, it took a full twenty minutes before Chen Dong finally ran through the entire corridor. There was no place in his body intact, and a large area of ​​purple spread from his shoulders to his calf.

"Fortunately, I didn't hit the face." Chen Dong grinned and teased.

Song Qiaoqiao then came out of the rubber stick jungle. When she saw her appearance, Chen Dong could no longer laugh. He rushed to Song Qiaoqiao in two or three steps and looked at her with heartache.

"What's wrong with your hand?"

Song Qiaoqiao drooped weakly with one hand, hugged her arm with the other, and there was a little pain between her eyebrows.

"It's nothing, maybe it's a fracture." Song Qiaoqiao said lightly.
Chapter completed!
