Ouyang Houtian paused here as he spoke, looked at Fang Shi, and saw that Fang Shi didn't mean to speak, so he continued: "According to the observation of the Gate, at this point in time, every month or so, there will be a small peak, and the time occurs on the night of the full moon. ”

Fang Shi interjected with a smile: "So, it's tonight?" ”

"Tomorrow night."

Ouyang Houtian said with a smile.

Xia Yuxin pouted and said, "No, it should be the fifteenth day of the lunar calendar, why is it tomorrow night?" ”

Lin Tianyin sneered: "Miss Xia, you are mistaken, our sect master is talking about the 'full moon night', not the fifteenth day of the lunar calendar. ”

Xia Yuxin then remembered the phenomenon of the 15th moon and 16th round, the calendar will be wrong, but the full moon will not be wrong, so the full moon should prevail.

Xia Yuxin didn't argue, if it's wrong, it's wrong, she nodded generously and said, "It's me who thinks wrong, please continue." ”

Lin Tianyin was about to take advantage of the victory to pursue, who would have thought that Xia Yuxin would directly and generously admit her mistake and not entangle with her, Lin Tianyin suddenly felt a sense of frustration that she was ignored, she was so angry that she gritted her teeth, but she didn't continue to say anything.

Ouyang Houtian glanced at Lin Tianyin and continued: "Basically, this is the situation that we have mastered, and we have not come to a conclusion about what is contained in this change, but according to the number, it seems that the intensity of the change is gradually rising, especially in the last sixty years, the climate and water flow changes in this sea area have become more and more intense. ”

Fang Shi smiled: "Is the sect master worried that there has been a big deviation in the formation of Yingzhou Cave Heaven?" ”

Ouyang Houtian put away the smile on his face, nodded and said, "Yes, a certain family does have this worry." ”

"Doesn't the sect master think that the result of this change is the failure of the Yingzhou Cave Heaven's Talisman Array? Wouldn't that be able to go straight to the cave? Now that the owner of the door is in a hurry to ask us for help, isn't it a bit of a loss? ”

Ouyang Houtian smiled bitterly and shook his head: "Elder Fang's words are wrong. Let's not talk about whether the final result of these changes is whether the Yingzhou Cave Heaven Mountain Protection Array fails, even if it is, what will happen to the sudden failure of the Mountain Protection Array, no one will know, what if the Yingzhou Cave Heaven is poured into the sea? What if the mountain protection array is discovered by foreigners when it fails? Or maybe something else unexpected, anyway. There are so many variables that a certain family is not willing to take this risk. Yingzhou Dongtian is very important to a certain family, to our door, and even to Huaxia Xuanmen, if possible, a certain family does not want any accidents. ”

Fang Shi nodded. He didn't expose Ouyang Houtian's unspoken plans, the reason why Ouyang Houtian so generously proposed to explore Yingzhou Cave Heaven together, in fact, he didn't expect to be able to enter the Cave Heaven in his heart, and the purpose of his invitation to Fang Shi was to let Fang Shi confirm whether the changes in the Yingzhou Cave Heaven Mountain Protection Array would lead to the consequences of Yan zhòng, if there would be no consequences of Yan Zhan. Then, due to staying here for a long time, Fangshi and the military will definitely evacuate, while the Earth Demon Gate can slowly wait for further changes in Yingzhou Dongtian.

As for the next exploration, the Earth Demon Gate is not prepared to involve Fang Shi, as for the military, it depends on the development of the situation, as well as the final result and time of the change in the situation.

However, Fang Shi didn't think so. Since he is here this time, he has to go to Yingzhou Cave to visit, he doesn't want to run in vain.

"Okay. What did the master of the door plan? ”

"According to a certain family's plan, we will explore the entire sea area in the next three days, of course, the focus is on tomorrow night."

"How to explore? Sitting in a submarine? ”

Xia Yuxin asked curiously.

Ouyang Houtian smiled: "Of course not, we can swim outside the submarine through the guò torpedo tank." ”

"Oh, dive. I like it. ”

Xia Yuxin said with a smile, and glanced at Xia Yuyao after speaking. Xia Yuyao was a little baffled, but she found that her sister's gaze was always rolling around her chest. It was immediately clear that my sister was not very confident in her own breasts, Xia Yuyao couldn't help but laugh secretly.

Xia Yuxin was a little embarrassed by Xia Yuyao's smile, and glanced at Fang Shi weakly, but fortunately Fang Shi didn't pay attention to the small movements of the two sisters at all.

Fang Shi nodded when he heard this: "Okay, then we will take turns to go out to probe." ”

"Let's act together, at least, and keep every action involving people on all three sides."

Ouyang Houtian added, Fang Shi naturally would not disagree, but he couldn't help but feel a little disappointed in his heart, originally he wanted to have a two-person trip to the bottom of the sea with Xia Yuyao, but now it seems that it can't be done.

"Okay, then it's decided, park the submarine, how deep is the water here? How deep can we dive with the equipment? ”

Seeing Fang Shi looking at him, the captain hurriedly replied: "If you use equipment to dive, it is up to three hundred meters, and the small submarine with deep diving on our submarine can dive to a depth of several thousand meters, but the bottom of the sea here is not so deep, the average sea depth is about eight hundred meters, and there are one thousand two hundred meters in some places, however, that kind of place is not suitable for deep submarine operations, and the terrain is too complicated." ”

"Are deep-diving submarines big? Demanding terrain? ”

Fang Shi asked a layman's word, and the captain smiled slightly: "No, because the deep-sea submarine is small in size and the power system is relatively weak, and in the sea area with complex terrain, the currents in the deep sea are often relatively turbulent, so this small submarine will be pushed by the sea water and cannot sail steadily." ”

Ouyang Houtian smiled and interjected: "There's no need to dive into such depth, if the portal of Yingzhou Cave Heaven is in the deep sea, how can those old masters enter and exit?" At that time, they didn't have the deep-diving equipment they have now. ”

Fang Shi thought about it, however, this possibility is still there, if the ancients can travel through the space for a short distance like the empty golden winged Gu, they may not be able to open the entrance and exit in the deep sea, in this way, just relying on the sea water can block a lot of external threats, the more Fang Shi thinks about it, the more it makes sense, but there are two important problems here, one is the positioning problem, how do they position themselves in and out? The other is a spell that can make people travel through space, at least, Fangshi doesn't know this spell yet.

Diving equipment will be carried by every submarine, not to mention that this is a special submarine, which usually undertakes a large number of scientific research tasks, and there is no shortage of these equipment. Beforehand, Ouyang Houtian also asked the military to make preparations, especially to bring some sophisticated diving equipment.

These devices are thin, sturdy, and have a long service life, and they also have underwater digital terminals, which can facilitate communication and data collection.

The first batch of people to go out of the boat were Fang Shi, Xia Yuxin, Ouyang Houtian and He Yuanqing. The rest of the people stayed, and the location of the boat Ouyang Houtian was chosen due west, and Ouyang Houtian felt that this place was most likely where the portal was located.

The submarine exceeded 10,000 tons, and the potential underwater looked like a giant beast, and at this time, the front end of the giant beast opened several original holes, and several figures came out of these holes.

As agreed before the boat departed. After coming out, the four of them acted together, the command room of the operation, Fang Shi, and the submarine was commanded by Xu Liquan.

They all wore waterproof communicators that could hear voice commands and information coming from inside the boat, but they couldn't speak. Because they didn't wear a water mask, they just bit the breathing apparatus and dive with an oxygen tank on their backs.

However, they can communicate simply through gestures or digital terminals on their arms, and after getting out of the boat, they first checked that the communication equipment was working properly, and then checked that there were no problems with the diving equipment, and then everyone swam towards the reef group under the guidance of Fang Shi.

The reefs look like mountains on a chart, and on a submarine, they look like mountains, but when you swim closer. It resembles a huge forest of rocks, with a reef covered with shellfish and seaweed, and a variety of fish swimming around. As if attracted by the light of the ashlar, many bold and curious fish swam to them and wandered, especially a fish with a slender head with a spike, which boldly rubbed against the body of the ashlar.

Bypassing a pillar of the reef, Fang Shi and the others disappeared into the submarine's television lens, and the sonar could still hear their swimming and breathing. Xia Yuyao turned her gaze to the lens of the small monitor they were carrying, and the signal was normal. Xia Yuyao breathed a sigh of relief.

However, her heart did not settle for long. Soon, the signal began to interfere.

"Master Fang, there is signal interference, please place a transponder here."

Xu Liquan shouted into the microphone, although he tried his best to control his feelings, but his voice still seemed a little nervous.

Fang Shi replied with a digital terminal 'ok', and soon, the image returned to normal, in the picture, the transponder on He Yuanqing's back had been fixed on a reef by Fang Shi and others with a belt.

"The signal is normal and the strength is good. You can move on, does Master Fang know the cause of signal interference? ”

Xu Liquan and the others waited for a while before Fang Shi replied.

"The influence of the formation, the position we are in has entered the scope of the direct impact of the formation, and if we continue to go deeper, the signal interference will be stricter."

"Master Fang, for the sake of safety, it's better not to go beyond the range of signal transmission."

"Okay."

This time the reply was very fast.

Fangshi They didn't have to take risks, the exploration just began, they continued to go deeper, and installed transponders and beacons along the way, and the forwarding distance of these transponders was also very limited, only about two kilometers, so the four of them took four transponders, and at most eight kilometers in a straight line, of course, they could not go in a straight line.

When they swam to the edge of the range of the second transponder, they found that the stone forest in front of them had become a stone wall, and it seemed that this was a large reef in the center, which was about 3,000 meters in diameter from satellite images.

Seeing this reef, everyone breathed a sigh of relief, and Ouyang Houtian quickly found some equipment they had left behind, but this equipment had been wrapped in a piece of seaweed, so it was no wonder that there was no way to pass it out.

Ouyang Houtian's gloved hand wanted to pull out the seaweed, who knew that his hand was just stretched out, and suddenly a black shadow emerged from the seaweed, and quickly pounced on Ouyang Houtian's fingers, Ouyang Houtian reacted very quickly, and quickly withdrew his hand back, but it was still slow.

"Hmm!"

Ouyang Houtian snorted, Fang Shi saw that the black shadow had shrunk back, but just now, Fang Shi had already seen the image of that guy clearly.

"Cave newts? How can it be in the sea? ”

Fang Shi was secretly surprised, and then looked at Ouyang Houtian's finger, a trace of blood spread in the seawater, it seemed that it was bitten, Fang Shi pointed to Ouyang Houtian's finger, Ouyang Houtian nodded, his right hand touched the wrist of the bitten left hand, and a ripple of yin and yang breath spread rapidly, Ouyang Houtian was planning to use magic to expel poison and seal the wound.

It's just that why is this spell fluctuating so weak? Xia Yuxin looked at Ouyang Houtian with some curiosity, but was shocked to find that the aura around Ouyang Houtian's body was declining rapidly, the situation was not right. (To be continued) R580
