In other words, this is already a water pipe, they are not fish, and they can't breathe in the water pipe, and there is only a dead end.

Su Jinyao's heart began to sink, and this situation was obviously in a desperate situation.

But Gu Xuebin didn't want to give up, he came here to rescue Su Jinyao. Even if it was just for Su Jinyao to hold on for a moment longer, he would work hard to the end.

Gu Xuebin patted Su Jinyao's leg and signaled that she didn't need to panic, and he continued to swim forward.

Su Jinyao understood that Gu Xuebin hoped to swim against the current, find even a space to be able to breathe, and then continue to move forward.

Su Jinyao paddled vigorously with one hand, and raised the other hand upward, touching the cave wall lightly, trying to find a little space for them to breathe.

After swimming for a while, Gu Xuebin felt extremely stuffy in his chest first, and after paddling a few harder, the air in his lungs was

Completely depleted.

Even if his lung capacity is much larger than Su Jinyao's, he is carrying a person on his back after all, and his oxygen consumption is much greater than Su Jinyao's.

Su Jinyao obviously felt that Gu Xuebin's movements were uncoordinated, and knew that he had reached his limit. In this way, there is no hope of persevering at all, and if Gu Xuebin drowns, Su Jinyao will not want to look for any more opportunities.

Thinking of this, Su Jinyao pulled Gu Xuebin's cheek with one hand, covered his lips, and gave him the qi in her chest.

At first, Gu Xuebin was stunned for a moment, and unconsciously opened his mouth. But when Su Jinyao crossed his breath, he immediately understood Su Jinyao's intentions, and closed his lips vigorously.

This is a critical breath, if Su Jinyao gives it to him, then maybe Su Jinyao will lose the opportunity.

Su Jinyao refused to let go, hugged Gu Xuebin's head tightly, and slowly traced his lips with her tongue, trying to make him open his mouth and accept his anger.

Gu Xuebin finally couldn't hold on, he couldn't refuse the kiss given by the woman he loved, and he even had a kind of despair, if he couldn't get out of trouble at the same time, he would rather live and die with her.

Neither of them continued to paddle, and they slowly sank together. At the same time, they lost the consciousness of survival, and they all regarded this moment as the eternity of two people.

This underground waterway was originally not high, Su Jinyao and Gu Xuebin kissed and sank, so Su Jinyao took the opportunity to untie Gu Xuebin's clothes that tied her, turned to his front, and hugged him tightly.

Gu Xuebin trapped Su Jinyao in his arms with both arms, and the water flowed slowly, pushing the two of them to a stone wall.

But suddenly, Gu Xuebin and Su Jinyao both felt that the water around them was rushing, as if there was a suction force pulling the two of them in one direction.

Outlet?!! If it is not an outlet, it will not allow the water to suction.

Su Jinyao and Gu Xuebin had a heart, grabbed each other's hands at the same time, and swam along the suction together.

The further they went, the greater the suction, and the two of them struggled forward with the current, and they felt that the compression around them also increased, and they should have entered a cave again.

A moment later, both of them felt a light on the top of their heads at the same time, and then they rushed out of the water.

"Huhu" Su Jinyao gasped for breath, and then hurriedly blew up the fire fold in her hand.

Sparks splashed everywhere, and faint small flames slowly ignited. As the flames increased, Su Jinyao and Gu Xuebin both saw clearly that there was a large space in front of them.

But this place is surrounded by stone walls, and the firelight can only reach a limited place, so there is no exit for the time being, and there is no place to climb up and shelter. But there was enough oxygen in the space for them to breathe.

Gu Xuebin took two more breaths, and then said, "Jin Yao, you wait here, I'll go pick up Mo and A-Ning." ”

"Well, let's go." Su Jinyao thought that the two of them would also encounter the same situation as Gu Xuebin, so she said, "The two of them don't know if they will give each other a ferry." ”

Gu Xuebin smiled when he heard this, but immediately dived into the water without answering.

The master can turn back to save the shadow guard, not to mention that this master is still His Royal Highness the Crown Prince, this is probably a great miracle for the entire Cloud Dome Country.

Soon, Gu Xuebin came back with Mo. However, A-Ning was already in a coma and was carried by Mo.

It seems that the two of them really don't have the good luck of Su Jinyao and Gu Xuebin, if Gu Xuebin doesn't go back, they may not find here.

Breath-holding exercises

The four of them got together again, and Su Jinyao woke up A-Ning first. A-Ning was in a coma because he had been closed for too long, but the shadow guard had received special training and remained breath-holding after being unconscious, so he didn't choke on water.

A-Ning was in a very bad mood after waking up, probably because of the lung injury, and this time he held it for too long.

Mo also looks very uncomfortable, and he has probably reached his limit. Leaning against the stone wall, he couldn't stop panting, and his face was all blue and gray.

Gu Xuebin swam over, hugged Su Jinyao's waist with one hand, and climbed the rock tightly with the other hand, and the two of them rested on the stone wall together.

Su Jinyao's feet didn't need to tread water, so she grabbed Gu Xuebin's neck and lifted the fire fold in her hand high, hoping to observe this hole more clearly.

It's just that the fire in his hand still doesn't shake much, so it can be seen that there is no circulating wind blowing in here, that is, there is no exit.

Gu Xuebin looked up at the dark space above and said, "Why don't I climb up and take a look?" ”

"No, I think it's closed too." After Su Jinyao finished speaking, she thought about it again and said, "But I guess that the structure of this mountain seems to be like this, the underground waterway and these many large and small cavities, so we should be able to use these cavities to continue moving forward." ”

Su Jinyao said, and told Gu Xuebin in detail about her thoughts.

First of all, Su Jinyao would fall from the gourd-shaped tunnel, a crack that suddenly appeared because of the earthquake.

But the magnitude of the earthquake was not very large, and the creation of such a large crack undoubtedly proves that the mountain itself is empty. And Gu Shangqing's previous discoveries also clearly prove this.

Therefore, Su Jinyao just wanted to use these large and small cracks or caves to ventilate, and then gradually move forward.

But for the sake of safety, Su Jinyao suggested that one person go to explore the road at a time.

The pathfinder tied a rope. Whether it is forward or backward, there is a rope as a traction. The person in the back can also quickly move to the next space according to the rope.

This plan is the safest plan for now, there won't be too many people going to venture until the next exit is found, and the rest of the people can rest here.

Mo turned his head and said, "Master, I understand what the crown princess means, I'll go find the next exit first." ”

Su Jinyao nodded without waiting for Gu Xuebin to speak: "Okay, you and Che will go to find the exit at one time, and Ah Ning and I will rest here more." This time you go first, but you have to do an experiment first. ”

"What experiment?" Mo obviously didn't understand what the experiment proposed by the crown princess at this time meant.

Su Jinyao said: "There is a lot of space here, and the air is at least enough for us to rest for a long time." The only downside is that you stay in the water all the time. So we are in no hurry to get out unless there is the next better place to move again. ”

Mo nodded, but still didn't understand what the experiment Su Jinyao was talking about.

Su Jinyao continued to explain: "So, you and Che are now practicing breath-holding, so that I can accurately grasp how long you can hold in the water. Once the rope is tied, I'll time you here, and I'll pull the rope to remind you halfway through your breath-holding limit. That way you will have enough time to return so that you will not drown because you can't find your way back or don't have enough breath. Remember, the four of us are now grasshoppers on a rope, and any one of us has a very big role, so don't be separated, and you can't give up on yourself easily

all hope to go out alive. ”

Su Jinyao's words are undoubtedly reminding everyone that living together is each other's hope.

If one person suddenly gives up at this point, it will also be a blow to the rest. Maybe a little relaxation, and the others will give up.

Mo listened and nodded, and looked at Gu Xuebin again.

Gu Xuebin smiled at him, reached out and patted him on the shoulder.

At this moment, A-Ning regained some of his spirit, called out "Mo", and then took out something from his arms.

Mo turned his head, and A-Ning threw over the number plate that was written on him.

After Mo stretched out his hand to take it, his eyes were suddenly full of surprise. Then he looked up at A Ning, then at Gu Xuebin, and finally his eyes fell on Su Jinyao.

Mo has always been with Gu Xuebin, and he knows that Gu Xuebin did not ask him for a number plate from the Shadow Guard Pavilion.

A Ning said: "That's right, my master asked the pavilion master for two number plates, yours and mine." ”

At this time, Mo got this number plate, which undoubtedly gave him the greatest hope. No one would want to die after gaining precious freedom.

Mo took a deep breath and made a few obvious swallowing movements before turning his head to look at Su Jinyao and said, "Crown Princess, Mo will definitely do his best to bring you out of here safely." ”

"Well, all of us will get out of here safely." After Su Jinyao finished speaking, she pointed to the surface of the water and said, "Now you guys start." It is very important for me to master the limits of your breath-holding. ”

Gu Xuebin and Mo glanced at each other, and both of them began to inhale heavily. Then they all plunged into the water together and began to hold their breath.

Looking at this scene, it was like two and a half children stabbing at the game.

Su Jinyao stared at the water and counted the time silently in her heart, not daring to relax at all.

After about three or four minutes, Mo first emerged from the water. After coming out of the water, Mo's face turned blue again, and it could be seen that the oxygen consumption was huge, and the red blood cells in his body were active to the limit.

This time is the limit of ordinary people's breath-holding, and Mo did not exceed this limit because he was a shadow guard.

But Mo has injuries on his body, and he has struggled in the water for so long before, it is beyond ordinary people that he can still reach this state.

After a while, Gu Xuebin still didn't get up. If it weren't for Su Jinyao still holding Gu Xuebin's hand, she would almost think that something had happened to this guy.

Su Jinyao gently squeezed Gu Xuebin's hand with her hand, and felt his response, so she was relieved.

After another while, even Mo showed a shocked expression, and Su Jinyao felt Gu Xuebin move. And then he slowly surfaced.

At this time, Gu Xuebin's face was only pale, and it was not too ugly. His breathing was much more rapid, but not so violent that he gasped for air.

Su Jinyao silently calculated. The duration of the anon-breath is about four minutes, which excludes the oxygen consumption when he swims in the water. If you take action, three minutes is the limit.

And Gu Xuebin was holding his breath underwater for about seven minutes just now, but Su Jinyao planned to take five minutes as a limit for the sake of insurance.

Gu Xuebin suddenly said: "Mo, I'll teach you a way to extend the breath-holding time." ”

Let Gu Xuebin ventilate A-Ning?

Gu Xuebin said that he could teach Mo a way to hold his breath for a longer time, and then he swam over, pressed it on several acupuncture points in his dantian and other places, and gave him a formula.

Su Jinyao can't have internal strength, so she is also covered by clouds and mountains when she listens to it.

But Mo expressed surprise after hearing it, and then began to experiment according to what Gu Xuebin said. After a while, Mo said to Su Jinyao: "Crown princess, I want to try again." ”

Su Jinyao understood that Mo probably really learned something. He nodded and said, "Don't be too reluctant, it will be harmful to your body." ”

Mo nodded, took two deep breaths, and then sank violently underwater. This time, he did hold his breath for a lot longer, and it took more than five minutes for him to come to his senses.

Su Jinyao couldn't help but look at Gu Xuebin, and felt that Gu Xuebin's method was really too good.

Gu Xuebin explained with a smile: "It's very simple, I just found out. As long as you stabilize your breath in these acupuncture points, wait until your breath is about to run out and then fall out, and let the breath in these places circulate in your body, it is equivalent to taking a small breath, and you will naturally be able to increase the time of holding your breath. ”

Su Jinyao is not interested in these, and she can't use them at all without internal strength. But A-Ning also thought deeply about it when she heard it, and then nodded, indicating that she had also learned.

Now that the experiments are over, Su Jinyao set the limit safety time for Gu Xuebin and Mo at five minutes and four minutes respectively.

After agreeing on the signal to exchange news, Mo tied the cloth rope they had rubbed earlier around his waist, and after taking a few deep breaths, he was ready to go to the next exit like water.

Su Jinyao also advised: "Don't be reluctant, if you receive my prompt, you must come back, otherwise we will pull you back directly." ”

Mo agreed, and suddenly sank into the water.

However, Su Jinyao noticed that Mo was like water and glanced in the direction of A Ning.

A-Ning also stared closely at the direction of Mo Rushui, as if the ripples in the circle were all her comfort.

Su Jinyao glanced at the fire fold in her hand and blew it out in one go.

In the darkness, she could perceive the rope in her hand more clearly, and she would not miss the signal from Mo.

At the same time, Su Jinyao also counted the time silently in her heart, and once she reached the middle of the desert's limit time, she would send him a signal to return, so that he would not go too far and have no time to come back.

After sending the signal, Su Jinyao was anxiously waiting for Mo to return or find information about the next exit.

After waiting for a while, Mo sent a signal from the other to signal that it was safe to let them pass.

Su Jinyao's heart was overjoyed, and she immediately blew up the fire fold, turned her head to Gu Xuebin and A Ning and said, "I found it, Mo let us go." ”

Su Jinyao immediately replied to Mo, asking him to pull the rope and wait over there, and they were ready to go over.

However, at this time, Su Jinyao was stunned for a moment and found a serious problem: there was not enough time!

From the time Mo went to find the exit to the time when the news came, it took at least nearly four minutes. Even if Su Jinyao and the others walked along the rope, they didn't have to waste time looking for it, but they needed to hold their breath for at least two minutes.

Su Jinyao's breath-holding time could have easily reached three minutes. But she's not in good health right now, and she's not sure if she'll be able to get there.

Then, Su Jinyao looked at A Ning again, she knew that A Ning had an injury to her lungs, so she wanted to

Reaching this three-minute limit is even more difficult. It's not a question of whether the training is successful or not, but a problem that inevitably arises with impaired lung function.

The reality is in front of us, either find a closer ventilation point, or ...... Abandon Anin.

Ah Ning looked at Su Jinyao's expression from the firelight, and she obviously also thought of what Su Jinyao was worried about.

A Ning said directly: "Master, you go over first." I'll give it a try slowly, and maybe it will work. ”

However, it is clear that this answer is undoubtedly saying: you go first, I will stay, leave me alone.

Su Jinyao said: "You go in the middle, and Che and I are at the end." As I said earlier, we all have to persevere, and no one can give up on our companions, let alone ourselves. ”

"Master, if I continue to follow you, I may have to shorten the trip every time. And the longer you stay here, the greater your danger. After Aning finished eagerly, he added: "It's not hopeless that I stay here. Maybe after a while the water recedes, I can still get out. Or when you get out, find another way to take me out. ”

The other methods are gambling and speculation, and I don't know how far this method can go.

Maybe they can't find the next vent, and they're still going to be trapped. Not to mention coming back to save Aning.

And if the water keeps rising, the situation will be even more dangerous. So A-Ning's request to stay here now is no different from giving up his life directly.

Su Jinyao thought for a moment, then insisted: "A-Ning, you go in the middle, and Che and I walk behind you." If it really doesn't work...... Just let Che Du Qi give it to you. ”

At the critical moment, Gu Xuebin gave A-Ning artificial breathing, which was a life-saving move. Even if Su Jinyao and Gu Xuebin are unwilling, A-Ning is definitely not willing, but ...... Is there any other way? No.

A-Ning was shocked when he heard this, and then smiled bitterly.

But before she could speak, Su Jinyao said:
