Except for Wei Xiaoyu and Zhou Xuan, everyone else is a real diving master, so they are familiar with the road in a diving suit and can be done in a short time, while Zhou Xuan and Wei Xiaoyu are a little worse, and they can only be regarded as pseudo-masters. Pen, fun, and www.biquge.info

It uses abilities to make diving ability super strong, but the actual movement and understanding of diving and adaptation are still inferior to others in nature.

Zhou Xuan is slightly better than Wei Xiaoyu, and he has experienced it a few times in the United States, but it is far from those masters who do diving sports every day. Although there is experience, but the actual experience is far worse, but there is a special ability in the body, but it can offset any lack of experience, the action is not as good as others, it is not as good, anyway, as long as the diving time is stronger than others, it is enough.

Because of what happened in Black Dragon Pond, An Guoqing no longer despised Zhou Xuan's clumsy movements, but felt that Zhou Xuan was just pretending to be a pig and eating a tiger, and he could move freely under the water at a depth of 250 meters.

After a few minutes, all eight people were wearing wetsuits and equipment, but all eight of them had nervous expressions, but each had a different mentality.

An Guoqing is nervous about whether he can pass the hurdle that he couldn't cross before, and what kind of dangers he will have in the future, but it is this hurdle that he can't cross for more than ten years has become a problem in his heart, and he thinks about this problem all the time.

But what Zhou Xuan was worried about was whether he could find the Nine Star Beads, which was the key.

The others, except for that Roger, were a little scared because of the previous encounter in Black Dragon Pond, but they fought for money.

Of course, this has to be except for Wei Xiaoyu and Fu Ying, the two of them will never pay for An Guoqing's little money, from beginning to end, Zhou Xuan and the two of them have never had financial cooperation with An Guoqing, Wei Xiaoyu is only because of Zhou Xuan, and Ran Ying was driven by Zhou Xuan's curiosity, on the one hand, he didn't believe what Zhou Xuan said, and on the other hand, he was shocked by Zhou Xuan's strange ability, and at the same time was shocked by the facts Zhou Xuan said, and came with him to explore in this skylight underground river.

Although Zhou Xuan hadn't been in the water yet, his ability had already been transported to probe in all directions. The underground here is really complicated, there are several underground rivers, but within fifteen meters of the inlet in front of me, this waterway is not connected with other underground rivers, and there are five connections after fifteen meters, because the distance of Zhou Xuan's detection can only reach more than fifty meters, so it has not been able to detect farther.

After getting ready, An Guoqing waved his hand, and brothers Wolf and Daniel went into the water first, followed by Roger, Zhang Yage, An Guoqing, Zhou Xuan, Wei Xiaoyu, Fu Ying, and eight people went into the water back and forth, and turned on the diving lights at the same time as they got into the water.

Before entering the water, eight people have tied the guide line, at the gas cylinder on each person's back, two guide reels are fixed, each is 500 meters long, in the complex underground dark river, the guide line is the only guide that can work the route home, this is no better than on the land, the land can use the compass, draw the secret mark, and the communicator, but in the underground dark river, these can not be used, the magnetic field under the ground is large, the role of the compass is useless, and in the yin river, the secret mark is useless, No matter what marks you draw in the current, it will be washed away, and the communicator will seriously reduce the call quality after cutting corners and obstacles, and of course, it will not be possible to talk at all.

After everyone went into the water, An Guoqing said: "Communicator detection, have you heard it?" Hear it, please answer! ”

"Hear!"

"Hear!"

Everyone in front and back answered, and then dived.

The entrance of this skylight is different from other underground rivers, the general underground river will be parallel or slightly inclined, in the shape of a front and back river, and this entrance, as soon as the water is down, almost 90 degrees of right-angle sagging, and the entrance is only more than two meters wide in diameter, but after going down to five or six meters deep, the underground is getting wider and wider, to more than ten meters deep, the underwater width is almost seven or eight meters.

At a depth of about 20 meters, the underground water hole is inclined and obliquely forward, but the terrain is still downward, and after more than ten meters, there are five water holes in front of the underwater hole, one of which is obviously flowing water out, and the outer four are the holes where the water goes.

An Guoqing said: "The one that comes out of the flowing water does not need to be explored, and the other four will meet after more than eighty meters, so any of these four can go to the same place, but the place where they meet, there are more than a dozen forks, we have detected each fork hole before, but they can only advance a distance of seventy or eighty meters, and then there is no way to move forward, each dark river is more than two hundred meters deep at that distance, there was no way to get through it before, and now it will be said there!" ”

Then An Guoqing pointed to a slightly larger hole, the larger one is more suitable for more people to pass by, the sneaking speed of eight people is not very fast, but it is not slow, the gas of the diving cylinder, the very fine masters are much smaller than the loss of ordinary divers, this new type of gas cylinder ordinary people can support four and a half hours, but in the hands of these masters, it can support about six hours.

After Zhou Xuan entered the water, he secretly used his abilities to improve the physique of Wei Xiaoyu and Fu Ying, so that her two heartbeats were normal and not affected by the underwater pressure at all, which could reduce the loss of oxygen.

In the underground river, maybe just one minute more oxygen can also save lives.

Zhou Xuan also deliberately paid attention to the distance from Wei Xiaoyu and Fu Ying, in case there was any danger. Fu Ying didn't pay much attention, but Wei Xiaoyu was next to him at any time.

Zhou Xuan also transported the ability to the limit, although there was a loss, but it was only a detection, compared to the loss of transformation and devouring, it was negligible, when Zhou Xuan got the ice ability, the detection was also extremely expensive, but now it is different, for him, the level of loss is much lower than that that can be restored at any time, as long as there is no large loss of ability, just detection will not cost anything.

Not only is the depth of this underground water cave getting higher and higher, but there are countless stone stalactites protruding from the cave wall, as if this water cave was transformed from a karst cave before.

Sixty meters away from the water hole, the depth is no longer down, basically at a depth of 110 meters, the direction of the forward is only a slight inclination, and then 20 meters forward, sure enough, it meets with other exits, but it is like a maze in four miles, a total of thirteen holes.

An Guoqing no longer guides which way to go, because every time they came down to these days before, these holes could only go to 80 meters, and after getting there, because the depth of the underwater intersection to go forward would extend down, more than 200 meters deep, and it also exceeded the limit of what they could dive. Even the corpses of those who went down were swept away.

Zhou Xuan has been using his ability to detect the water molecules here since he was launched, and the strange thing is that the water molecules here do not contain the energy molecules after the transformation of the sun flame in the Nine Star Beads, that is to say, there are no molecules contained in the water in the well in Poxin Village, and it can be estimated from this point that the dark river of the seventh skylight is not connected with the water of the well in Poxin Village.

This measurement can't be wrong, because Zhou Xuan's current ability itself contains the kind of molecule contained in the well water of Poxin Village, that is, the ability after the transformation of the solar flame energy, although he has this ability, but Zhou Xuan still can't understand why it can make the people of Poxin Village drink longevity, and this energy is different from the ice qi ability.

In the past, Zhou Xuan's ice qi ability was to stimulate the functions of the human body, and then it could restore the body of the elderly to the point where it was more than ten years ago, but the ability of this solar energy molecule directly made the elderly live longer, but the molecules contained in the well water were extremely weak, so Zhou Xuan couldn't detect too many abnormalities in those old people in Poxin Village.

While Zhou Xuan was diving, he found that An Guoqing didn't say anything else, and thought in his heart, The origin of this Nine Dragons Ding on his body, An Guoqing couldn't say clearly, only said that he got it from the skylight of the three seas, which skylight did he get it from?

But why did An Guoqing come from this seventh sky window with them for sure? Could it be that the Nine Dragons Ding was obtained from this skylight?

I can't figure it out, unless it is Liu Zijie who got the Jiulong Ding back then, no one can figure out the real origin of the Jiulong Ding, but Liu Zijie has been dead for almost two hundred years, and I am afraid that this secret will be buried deep underground with him.

Thirteen forward cave entrances, An Guoqing has taken people to explore each hole before, and Gu is only about 80 meters away, so it doesn't matter which hole you choose.

The previous diving equipment did not support the human body to withstand the depth pressure above 200 meters, and the capacity of the cylinder was only two hours, and the current ultra-concentrated cylinder can reach the capacity of four and a half hours, which is the height that the previous diving equipment could not reach.

But even so, Shi Guoqing can't guarantee that he will be able to successfully get through that hurdle this time, because that side is always a mystery to him, a mystery that cannot be solved!

This time it was still a larger hole, at this time the pressure gauge showed a depth of one hundred and thirty-five meters, everyone was very careful to sneak, there was no air hole, it was completely in the underground river, which was more terrifying than in the Black Dragon Pool, although no strange things were found to run out, but in the Black Dragon Pool, as long as the water surface was returned to the human world, and here, there was still a dark and terrible underground river before and after, a bad one, maybe buried in this gloomy Yin River.

Because of the dangerous scene in the Black Dragon Pond, everyone was very careful, and Zhou Xuan even probed the depth and way of the Yin River in front of him.

Here, his ability detection is also a little blocked, it can't be as smooth as on land, it can't reach so far, at this time, even if it is condensed, it can only detect sixty or seventy meters, these rock cave walls can block his ability penetration, and it can only be detected smoothly in unobstructed water, but the Yinhe Cave turns around, not going straight, so the ability is also blocked.

Because the river has a curve, Zhou Xuan can basically only detect the distance of 30 meters in front, and it seems that the depth of half of the water is still increasing, and after diving for more than 30 meters, the water depth reaches 160 meters, and An Guoqing seems to be very nervous.

Because An Guoqing had come to this distance before, he basically didn't delay the time, and it only took a little more than an hour to get to the place where they couldn't go before.

In front of it is a deep water hole that slopes downward, and the water depth is two hundred and nine meters, An Guoqing stopped, and then said in a deep voice: "Everyone, pay attention, I have arrived here before, and then there is a hurdle that I have not been able to cross, everyone should be careful." ”

The guide line was almost half a wheel, and it should have been two hundred and fifty meters, that is, two hundred and fifty meters from the bottom of the skylight cave where they had gone into the water.

Although everyone's hearts were nervous, but fortunately, there was no abnormality in the diving suit, and the pressure did not feel abnormal, in the Black Dragon Pool, almost all of them dived to a depth of two hundred and fifty meters, of course, that was also the limit of several of them.

After diving more than thirty meters further, the water depth was almost two hundred and forty-five meters, even An Guoqing became nervous, this was a place he had never reached before, and there was a strange sense of fear spreading in his heart.

Zhou Xuan used his ability to protect Wei Xiaoyu and Fu Ying, and at the same time detected fifteen meters below, the Yin River reached the bottom, and what happened behind the thick and impermeable rock, he didn't know, but the water flow was a little weird there, and where he was now, the water flow was active, but it was not turbulent, and the light could be seen in the water.

At this time, the brothers Wolf and Daniel first felt that they couldn't support it, their heartbeat intensified, and they quickly stopped their sneaking movements and said, "Mr. An, you can't dive any further!" ”

An Guoqing hesitated, he himself can still support it, and Brother Zhang Ya and Roger can obviously dive some deeper, Zhou Xuan and Wei Xiaoyu Fu Ying are silent, but they must be able to dive deeper distance, if they want to return now, it will be the same as the efforts of the previous ten years, it will only be in vain, but they are unwilling in their hearts.

An Guoqing paused, but still asked for the opinions of others, and asked, "What other opinions do other people have?" ”

Before An Guoqing came, he signed a contract with these people, if he returned before the goal was achieved, each person would only pay 300,000 yuan, and if the goal was achieved, he would pay 1 million yuan, the mission was successful, and there was an indefinite amount of bonuses, and it was also guaranteed that the bonus would never be less than the remuneration, that is, if the purpose required by An Guoqing was achieved, the reward plus bonus would be at least 2 million yuan!
