Because the indoor temperature was much higher than outside, after walking for less than two minutes, Chen Dong felt that his back was soaked in hot sweat, Song Qiaoqiao simply went barefoot and put two pieces of torn woolen sweater cloth into his pocket.

The corridor is lined with ordinary stone walls, without any ornaments or murals, and it looks extremely monotonous, and when you see such a huge building from the outside, it doesn't seem to be spacious after entering the door, which makes people feel a sense of visual confusion.

After walking for a few more minutes, the road finally came to an end, and Chen Dong took the first step out of the road, and his vision immediately became wider.

Outside the corridor, there is a place similar to the hall square, the lights are brilliant, but there is no one inside, and it looks very empty.

However, before Chen Dong had time to look at what was wrong in this hall, he was shocked by the scene in front of him.

At the front of the hall, from left to right, there are twelve holes of the same size!

Seeing this, Chen Dong couldn't help frowning, he stepped forward, randomly picked a hole, and looked inside, but found that it was dark inside, and he couldn't see anything clearly.

Repeated this twelve times, Chen Dong carefully observed each hole, and found that each hole was similar, the hole was inlaid with a metal door frame, and the space inside could roughly accommodate three people in parallel, but without exception, it was pitch black inside, making it impossible for people to peep.

"What now?"

Song Qiaoqiao didn't realize that since she walked with Chen Dong, she gradually began to get used to Chen Dong making decisions, and she herself was too lazy to think and judge.

"It seems that Rocha's intention should be to divert traffic." Chen Dong came to a conclusion.

Judging from the arrangement of the twelve caves, it is clear that this is a trick played by Rosha, no matter how many people travel in groups, the best way to get to this place is to act separately, so as to break up the crowd.

Think about it, there are twelve different choices, everyone's opinions must be different, no one knows what the situation is like behind each cave in the road, no one knows which choice is the right one, once the disagreement appears, each goes its own way, it becomes an inevitable situation.

And even if everyone wants to act in unison, in terms of the width inside, there will definitely be three people walking in front, and in case of a critical situation, even the retreat will be affected by the companions behind them, so choosing a hole with a three-person unit is the best choice.

"What's your lucky number?" Chen Dong suddenly turned to look at Song Qiaoqiao.

Song Qiaoqiao was stunned and replied, "Eh...... Nine...... 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, "Then what if you don't, anyway, in my opinion, every hole should be able to go out, it's just that the process design in the middle may be different." ”

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

With the help of the light in the hall, at first, Chen Dong could still see the road in front of him clearly, but as they continued to go deeper, the light around them became more and more dim, and soon the two fell into complete darkness.

Because he couldn't see, Chen Dong could only pull Song Qiaoqiao with one hand, touch the stone wall on the side with the other, and move forward slowly, fortunately, soon their eyes were lit up again.

After the two of them saw the things in front of them, their faces couldn't help but become strange.

Chen Dong grimaced: "Is this the legendary ......?"

"Go up the knife mountain, go down to the sea of fire." Song Qiaoqiao added.

I saw that in front of Chen Dong and Song Qiaoqiao, there were countless sharp knives with cold light, and dozens of flame guns, which were constantly spitting out scorching fire dragons.

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

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

After finishing speaking, Chen Dong began to carefully observe this "sword mountain and sea of fire", the handle of the steel knife was all submerged in the ground, and he could only see the blade standing up, with both sides open, and the cold air was rising, at first glance, it seemed to be arranged in a disorderly manner, but in fact, there were traces to follow.

And there is also a certain gap between each steel knife, some are big and some are small, and the big one is big enough for one person to pass through it, so if you just shuttle through the knife forest, it is still easy to be careful.

The key is the flame gun installed on the wall, which covers almost all the space on the tip of the knife, and if you are not careful, you will set yourself on fire, if you are burned by the flames, the pace of your feet will be disrupted, and it will inevitably hit the blade next to you in a panic, causing a vicious circle.

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

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

The flame spray guns inlaid on the stone walls on both sides do not breathe fire continuously, but after a period of time, there will be a short pause, but the pause time of each flame gun is different, there are slight differences, so it seems that the flames in it have never stopped.

After making this discovery, Chen Dong began to calculate the frequency and angle of the fire of each flame gun, plus the route of the knife forest on the ground that people can walk through, and made a comprehensive judgment, hoping to find a way to pass through here.

Such a calculation is undoubtedly extremely large and complex, Song Qiaoqiao did not dare to disturb Chen Dong, she stepped aside, and also tried to find the loopholes, but it didn't take long for her to feel a headache and retreat.

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

Chen Dong on the side was still motionless like a sculpture, his eyes were getting brighter and brighter under the reflection of the flames, and the sweat on his forehead was getting denser and denser.

Ten minutes later, Chen Dong rubbed his eyes, which had already begun to swell, turned around and said to Song Qiaoqiao with a smile, "It's okay, come with me." ”

Song Qiaoqiao's eyes widened, and she exclaimed, "You really found out?" ”

"It should be about the same, time is pressing, and there may be some deviations, but as long as you are careful, you can still walk through."

As he spoke, Chen Dong took Song Qiaoqiao's hand, and then instructed: "Listen to my orders for a while, follow closely!" ”

Song Qiaoqiao nodded, and at this time, she still chose to believe Chen Dong.

Chen Dong walked to the knife forest, looked up at the flame spray gun above, silently counted in his heart, and took a deep breath of hot air at the same time.

"Let's go!"

Suddenly, Chen Dong shouted, his figure jumped forward, Song Qiaoqiao reacted quickly, and almost kept up with Chen Dong's footsteps at the same time.

I saw Chen Dong stop and go, and everywhere he went, the flame spray gun on the wall happened to be extinguished, allowing the two of them to pass through calmly.

"Bend over!"

"Half a step back!"

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

……

Under Chen Dong's constant command, Song Qiaoqiao followed closely behind, but there were no mistakes.

The only time that the most dangerous thing was that Chen Dong's right leg was accidentally cut open by the blade, which made Chen Dong's footsteps pause for a second, and it was in this second that the flamespray gun that had been extinguished spit out a pillar of fire again, almost burning Chen Dong's face.

Fortunately, Song Qiaoqiao reacted quickly, reached out and grabbed Chen Dong's body that had already leaned out, Rao was like this, and Chen Dong also burned off a few eyebrows.

In the next step, Chen Dong was more cautious, but there was no more mistakes, and after the two of them finally walked through the "sword mountain and sea of fire", they couldn't help but gasp twice, especially Chen Dong, who has been in a high degree of tension and overload operation, once he relaxed, he immediately felt a headache.

"It's finally here!" Chen Dong sighed, looked back at the large firelight with palpitations, and finally realized what it means to dance on the tip of a knife.

Chen Dong ripped off his ski suit, revealing the tight muscles inside, after just a few minutes, Chen Dong's whole body was already soaked, and beads of sweat continued to drip down his muscle lines.

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

The rest of the road was relatively peaceful, and just when Chen Dong thought that the test was over, they came to a slender corridor.

The hallway was for one person only, and was lined with suspicious but familiar rubber sticks.

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

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

Chen Dong suddenly sounded Luo Sha once said that the ability to resist attacks is a compulsory course for them, so it seems that it is not difficult to understand that such a level appears.

"Looks like you can only break through?" Song Qiaoqiao also saw the role of this corridor, and her heart sank slightly.

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

After speaking, Chen Dong kicked his feet and rushed forward, because there was only one road, but there was no need to discern the direction, Chen Dong covered his head with both hands, and ran with his head down.

"Smack!"

"Bang!"

……

The rubber stick fell mercilessly on various parts of Chen Dong's body, making a muffled sound, and Chen Dong seemed to be back to the first day he came to the training camp, facing a brutal welcome ceremony.

However, the difference is that Chen Dong today is more than a star and a half stronger than he was at that time.

Chen Dong didn't dare to stop at his feet, almost bursting out of his greatest potential to rush forward, at this time, if he stayed for one more second, he would be beaten for one more second, and there were sticks up and down, left and right, and there was nothing to dodge at all.

Suddenly, Chen Dong felt that his calf was coldly pumped with a stick, a stumble, and he almost fell to the ground, but he didn't dare to fall, and he couldn't fall, Chen Dong stretched out his hand, directly grabbed the rubber stick that was swinging wildly beside him, stabilized his body, stayed in place for two seconds, and then ran forward again.

This time, it took a full twenty minutes for Chen Dong to finally run through the entire corridor, and there was no place on his body that was intact, and a large area of bruises spread from his shoulders to his calves.

"It's good I didn't hit me in the face." Chen Dong grinned and laughed.

Song Qiaoqiao also came out of the rubber stick jungle afterwards, and as soon as he saw her appearance, Chen Dong couldn't smile anymore, and jumped in front of Song Qiaoqiao in two or three steps, looking at her distressedly.

"What's wrong with your hand?"

Song Qiaoqiao drooped weakly with one hand, hugged her arm with the other, and looked a little painful between her eyebrows.

"It's nothing, it's probably a broken bone." Song Qiaoqiao said lightly.
