"Hey, Frank, you said this cave leads to the sea, so could there be creatures in this cave as well? For example, its own ecological cycle system or something? On the way forward, looking at the silent cave bottom environment around him, Chen Fan suddenly asked.

"I can't rule it out, but we haven't found out yet." Frank replied casually to Chen Fan.

"Do you think there will be some prehistoric beast or cave monster out of the darkness?" Chen Fan continued to look for trouble.

"Chen Fan, can you not say such things, it will only make me feel scared." Judy complained about Chen Fan.

"That's because you've watched too many movies, right? There are so many monsters. So you shut up for me now. Frank expressed regret for taking Chen Fan down.

"Okay, okay. You call it out. I just wanted to adjust the atmosphere. Chen Fan, who was bored, had no choice but to shut his mouth.

Soon, the three of them came to the deepest part of their previous exploration.

"Wait, my thruster is jammed." At this point, Judy was kicked up by the jammed master's thrusters.

"Wait, you see the speed of the silt flow here." Chen Fan pointed to a direction and said.

"yes, I see, it looks like there's another passage here." Frank stepped forward to pick up the stone.

"Looks like we've found the Demon Eye here at the Demon Limit." Seeing that the expedition had made progress again, Judy immediately smiled happily.

Chen Fan stepped forward to help Frank carry the stone blocking the way, "Are you sure it's not the devil's buttocks, Judy?" Oh! Frank, you look old, let me help you. ”

After a while, through the efforts of the two of them, they finally removed the stones blocking the road.

"It looks a little narrow, this road." After looking at the entrance of the cave in front of him, Chen Fan sighed.

"I'll go in and investigate, and I'll be back shortly, and you'll be waiting here." Frank finished speaking and got inside.

"It's not going to work Frank, we have to act together." Judy was not worried that Frank would enter the unknown territory and followed.

Chen Fan had no choice but to follow in, during which the entrance to the cave became narrower and narrower, and Frank discarded the spare oxygen cylinder.

Suddenly, Judy's equipment, which was walking in front of Chen Fan, was stuck, and Judy, who had not been rested for a long time, was getting worse and worse at the moment.

"Hey, Judy, I'm still behind your ass, don't worry, or I'll kick you off your ass, and maybe you'll be able to get out like a rocket." Chen Fan in the back felt that Judy's state was not good, and hurriedly eased the atmosphere.

Sure enough, being interrupted by Chen Fan like this, Judy suddenly relaxed and was in the mood to scold Chen Fan for being shameless.

After calming down, Judy adjusted her equipment and drilled out of the hole after a while.

Then Chen Fan followed Judy and also came out.

The space behind the entrance of the cave suddenly became larger, and the dialect looked like the Great Hall.

"Oh my God, I think we were the first people to get here, I dare believe no one has ever arrived here, we did miracles." Judy sighed as she looked at the new cavern.

"Looking at the upward trend of these bubbles, I see that this place is at least 100 meters above the ventilation zone." Frank pointed up.

"Do you want to go up and have a look? This could be a new cave system. Chen Fan proposed.

"No, do you want to stay here for 2 hours to decompress? We're here to explore, so let's go back and prepare first. Judy rejected Chen Fan's proposal.

"Okay, you're the boss, you say it." Shrugging his shoulders, Chen Fan followed Judy, who turned around and swam back.

At this moment, Chen Fan found that Judy's oxygen tube was leaking.

"Oh my God, Judy, your oxygen tube is broken." As Chen Fan's words fell, Judy's oxygen tube burst open.

Judy, who had no oxygen supply, suddenly began to panic, and her limbs danced back and forth for help: "Quick, take me to the air platform." Judy kept repeating the phrase.

Seeing the urgency of the situation, Frank hurriedly stepped forward to calm Judy down: "It's too far, we can't get there, you calm down, let's take turns using masks." ”

After saying that, Frank quickly took off the masks of the two of them and put his own mask on Judy's head.

"No, Frank, you can't do this, or you'll both die." George's exhortation in the headset.

However, Frank ignored it and gave the mask to Judy.

However, after taking turns twice, Frank wanted to take the mask back to breathe oxygen, but Judy, who was getting more and more flustered at the moment, clung to the mask and couldn't take it off no matter how much Frank tried to take it off.

Seeing Frank, who was gradually starting to suffocate, Chen Fan on the side suddenly arrived very anxiously, "George, what should I do?" The spare oxygen we had on us had been lost on the way in. ”

"Oxygen, Frank needs to breathe oxygen now, or he's going to drown." George's anxious voice rang in his ears.

"Oxygen? Yes, yes, oxygen. Chen Fan, who thought of something, hurriedly took out the oxygen concentrator that he had brought back from the space at the interstellar world.

Holding the oxygen concentrator, Chen Fan quickly put the straw into Frank's mouth.

Fortunately, although Frank began to be confined at this time, he had a strong sense of survival, and naturally began to inhale oxygen after Chen Fan inserted the oxygen concentrator straw into his mouth.

It didn't take long for his condition to begin to improve, and Frank, who was gradually regaining consciousness, gave Chen Fan a thumbs up after seeing the situation, and then carried the oxygen cylinder behind Judy and pointed the way back.

Chen Fan, who nodded in understanding, dragged Judy, who had entered a coma, and began to swim back, and behind him, Frank followed behind Chen Fan with an oxygen concentrator.

Half an hour later, the three of them finally returned to the oxygen platform where they had met Lizzie.

After coming in, Chen Fan and Frank suddenly collapsed inside, looking at Judy, who was still unconscious, the two of them who had survived the catastrophe finally breathed a sigh of relief.

"Chen Fan, I'm glad I brought you down, otherwise Judy and I would definitely have one person left where forever." Frank sighed.

"Hey, what's this, you can't see death without help, I see that Judy is going up to rest for a long time this time, it was so thrilling just now, you almost couldn't come back, I was stunned on the side." Chen Fan waved his hand and said indifferently.

At this time, seeing the three of them passing through the thrilling advance base, several people were also relieved at this time, and the situation just now made them break out in a cold sweat.

After a 2-hour decompression period, Judy also woke up, and she felt very guilty for her actions at that time. But Frank didn't blame her, after all, these are people's instinctive reactions after drowning, mainly because Judy herself has not rested for a long time, which causes her to be in a bad state.

When the three of them returned to the forward base, several women hugged each other and cried, and Josh, after knowing that he had almost lost his father just now, suddenly felt guilty for what he had done, hugging his father Frank and crying.

As the hero of this operation, Chen Fan was surrounded by Luke George and several people at this time, praising him for being able to have such a result in the first time he went into the water, and sighed that he was a diving talent.
