Chapter 5 The dilemma

Suddenly there was a sound of water around, and Cao Bo only felt a cold and salty smell of seawater around him.

And a stream of thick sea water poured down the pipe. The sea water hit the metal floor of the channel and began to splash countless splashes. However, when the sea water gathered to a certain extent, even the waves could not be seen, and only a vast expanse of whiteness was seen.

"Lord, they want to drown us!" Xu Chu looked at Cao Bo in a panic. If he wanted to talk about the land war, Xu Chu had not been afraid of anyone. Even if he was seriously injured, he dared to fight with the enemy.

However, Xu Chu is a dry duck. Just like many Cao Ying generals at the beginning, they are popular on land and on horseback, but as soon as they get to the water, they are simply slaughtered by others.

"Don't be afraid!" Cao Bo was also a little anxious at the beginning. After all, the whole passage was full of seawater. Although the gate in the distance has not been closed, it is not guaranteed that it will gradually close as before. If that's the case, if Cao Bo and others haven't solved the mystery of the trap and can't get out, then they will definitely be trapped to death. Here it is.

However, as the sea slowly flooded the channel and looked at the sea water flowing down from those pits, Cao Bo only felt a little relieved. As long as there are these pits, the sea water will definitely not be able to fill the channel for a while. As long as the exit over there is not closed for the time being, then it will be left to Cao Bozu. Enough time to think.

Cao Bo found this phenomenon, and Guo Jia and others soon found it one after another. Since there is a place for these seawater to vent, as long as you seize the time to find out the safe location, everyone can go out sooner or later.

"What a failure!" Jia Xu couldn't help sarcasm: "The person who made this organ must be an incompetent rat. One of the two organs can kill us, but if the two are used together..." Jia Xu hummed twice, obviously optimistic about his own prospects.

"Let's not be careless. Although the hole is far from here, there are also times when it is filled." Guo Jia was still calm and calm: "Zhong Kang, don't stop. We make more water outlets while moving forward. In short, it's serious to get out of this place early!" After Guo Jia finished speaking, he immediately got Jiang Gan's approval. Although Jiang Gan was the only one who could fly, and he could leave here at any time, Jiang Gan's loyalty to Cao Bo would never leave without permission even if he could.

Xu Chu promised, and then continued to step on the floor with the cooperation of Guo Jia and Jia Xu, but with his progress, Cao Bo felt something was wrong!

"Wait!" Cao Bo suddenly shouted, and Xu Chu immediately stopped when he heard the sound, and then looked at Cao Bo doubtfully. Obviously, he wanted to see what Cao Bo had to say.

"Twenty-four, twenty-five... thirty-seven, thirty-eight!" It only took Cao Bo a few seconds to count how many water points were in the whole tunnel. Just over a minute ago, Cao Bo felt that there were not so many water points.

When Cao Bo said what he found, several people were silent, and Xu Chu subconsciously stepped back half a step back and stepped on a floor. The floor shook slightly, and then sank in an instant with the flow of water. It seems that it was also a trap here.

"Look! There is an extra water point there!" At this moment, Jia Xu's eyes happened to fall on the roof of the shed not far from him, and a hole suddenly appeared there, and a water of clear water poured out from there, converging with the seawater from other water points and flowing down to the caves on the ground.

Jia Xu's discovery was also looked at by Cao Bo and others. Cao Bo suddenly felt a bad feeling, and then he quickly counted the number of water points again. This time, the result was just as he was worried about: thirty-nine! And this amount is the same as the number falling on the floor! Cao Bo didn't pay attention to this matter before, but now the result is indeed the same.

If Cao Bo does not speculate wrongly, the number of water inlet points and the number of exposed traps should be the same. Although it seems that there is no difference between 39 water points and 100 water points now, if you think about it carefully, you will know that the more water points you have, the more unfavorable it will be for Cao Bo!

Because the capacity of the cave below is fixed, if the flow of seawater at each outlet is the same, the larger the number of outlet points, the shorter the time for the cave to be filled. If the seawater finally overflows, even when the cave is not yet filled, the entrance will be closed, then Cao Bo and others are destined to I'm going to drown here.

At this moment, even Jia Xu, who had been sneering just now, did not say anything, because he finally found the mystery here. The crypt plus the water point is not the relationship between one plus one less than two, but the combination of these two factors to form a perfect killing array! A death trap that puts the people in the game in a dilemma.

"What should I do?" Xu Chu is now standing on a floor in a daze, and his shoes are wet with the splashing sea water. When he also understands what's going on here, Xu Chu doesn't even dare to say anything, for fear of making a more serious mistake.

There must be a regular here! Cao Bo still firmly believed in this, but Jia Xu suddenly asked, "Can the master be familiar with water nature?" Although Cao Bo can't say that he is well hydrated, he also lived at the seaside for a period of time. Even if the professional ones don't know it, it's no problem to swim two or three hundred meters in one go.

"Zhong Kang! Let's continue!" When Jia Xu heard Cao Bo's answer, he made up his mind: "Instead of stopping here and waiting to die, it's better for us to fight. If we win, we will all go out alive. If we lose, we will die here!" Jia Xu gritted his teeth, which was also in line with his character. When Jia Xu led the army to fight, he also liked the life-threatening trick of the Jedi counterattack.

"This..." After listening to Jia Xu's words, Xu Chu looked at Cao Bo hesitantly, because he knew the consequences of continuing to step down the floor. Xu Chu, who had always looked at Cao Bo, was still used to obeying Cao Bo's orders at such a critical juncture.

Guo Jia was also a little embarrassed, but when he turned his eyes twice, he seemed to suddenly figure out something. Then Guo Jia also asked Xu Chu to move forward quickly, but this time he didn't have to find the safety points in each row. He just needed to keep moving forward and find a straight Just go through the exit channel.

"Lord, it's not the time for us to think about other things. The closer we get to that exit, the more confident we are to get out of trouble!" Guo Jia's meaning, Cao Bo naturally knows that they have only advanced more than ten meters in total, and everyone is still more than 180 meters away from the exit. If the exit over there is about to close, even if there is no trap on the floor, it is impossible for anyone to run over in such a short time. That's why Guo Jia and Jia Xu reached a consensus on this matter: the closer to the exit, the more hopeful everyone will survive.

Moreover, Guo Jia and Jia Xu constantly take turns to explore the surrounding floor in the hole, and can also find out which floor is safe to a certain extent. Although the continuous infusion of seawater increases the difficulty of their search, and they are exhausted every time they come up, Guo Jia and Jia Xu did not complain at all. He We and Xu Chu advanced rapidly and orderly, but in just a few minutes, they advanced more than 30 meters, and the water point was only increased by more than a dozen, which was much more efficient than before.

"Lord." Jiang Gan has been stopping on Cao Bo's shoulder. He has been following Cao Bo for the longest time and knows Cao Bo's thoughts best. He knows that Cao Bo is dedicated to finding the law of traps, but now that time is running out, even a second may kill everyone.

"They are so anxious and desperate for the safety of their master..." Jiang Gan was about to persuade him, but Cao Bo waved his hand and said that it didn't matter. In fact, what Cao Bo cared about was not that Guo Jia and others didn't listen to him, but why he didn't solve the puzzle at the beginning? Because Cao Bo believes that there must be some conditions for the infusion of seawater. Maybe it is the number of floor drops to control it. If the rules are clear before that amount, then there is no need for everyone to risk their lives to seize time now!

As Xu Chu and others advanced rapidly, the sound of water from the cave became louder and louder! Obviously, the water level of the cave rose rapidly under the injection of a large amount of seawater, and the sound of water has changed from a very empty and distant distance to a loud sound of water! Moreover, Cao Bo faintly heard one or two strange sounds from the cave. The sound was a bit like the horn of a beast, but Cao Bo had never heard what kind of beast would make such a strange sound.

"Speed up! Come on, come on!" Jiang Gan urged anxiously. Although he had seen the tiredness of Xu Chu and Guo Jia, Jiang Gan also heard the sound from the cave. He had contact with Cao Bo and some monsters. Jiang Gan was afraid that there was something hidden under the cave. If the time dragged on, the situation of these people would be more dangerous. .

And why did Cao Bo and Jiang Gan hear the sound alone? There were also collapsed holes around Xu Chu and others, so these guys naturally heard it clearly.

Xu Chu suddenly straightened up and made a long roar. The sound was loud and strong, and it lasted for a long time in the whole channel! With Xu Chu's explosion, the sound from the cave suddenly disappeared. Obviously, the things below were also a little afraid of Xu Chu's voice.

Finally, when Xu Chu and others advanced to about 150 meters, the water in the cave was finally full, and a large amount of seawater poured into the channel began to gradually spread everywhere because there was no place to vent, and the seawater in the passage also began to gradually deepen.

"Attention, attention!" The annoying alarm sounded again: "There is seawater pouring in the B2 area, and the B2 channel is about to be closed. Please evacuate quickly..." Sure enough, this is exactly the same as Cao Bo's previous expectations!
