At a depth of 200 meters, Sima Yuru carried a compressed air bottle on his back to rhythmically carry out diving breathing, and a long series of fine bubbles appeared next to the diving mask from time to time, and the bubbles rose straight up to the sea water above like a pillar of smoke, and before the distance of how many meters had disappeared due to the strong water pressure, Sima Yuru shook his feet slightly at an accelerated pace, so that the duck fins worn on the soles of his feet stroked to push his body forward to keep up with the speed of Song Xiaoshuang's diving.

It is not a good thing to fall behind in this deep seabed, she has not forgotten the situation when hundreds of tiger sharks besieged Song Xiaoshuang not long ago, and for some reason, since she and Song Xiaoshuang cruised around the light gray reef-like energy weapon device for the second time trying to find a hidden entrance and exit, those tiger sharks with spotted stripes on their backs all escaped into the nearby sea water and disappeared after eating away at the corpses of their kind, if it weren't for the spread of blood stains in a large area of sea water near the bottom of the sea, Under the fluorescent lighting of the flickering green signal light on his waist, Sima Yuru was a little suspicious that the scene just now was like a dream scene, and he felt extremely unreal.

Song Xiaoshuang's figure moving not far in front of him was moving at a significant slowing speed, Sima Yuru knew that he must have made an important discovery, and after diving to Song Xiaoshuang's side with a speargun in his hand, he used the green fluorescence of the signal light on his waist to illuminate the convenience of the nearby seawater, Sima Yuru clearly saw Song Xiaoshuang gesture and asked if there were any signs of discomfort in his body.

Sima Yuru's head melon wearing a diving mask shook his head slightly, and inadvertently flipped his wrist to look at the diving watch with a luminous indicator. The one-handed speed gesture told Song Xiaoshuang that the two had been diving for nearly forty minutes, and even if there was an obvious discovery, they had to hurry. The remaining compressed air from the compressed air cylinders on the backs of the two of them can last for twenty minutes at most, although Song Xiaoshuang has an extra spare compressed air cylinder on his back, it is better not to use it as a last resort.

Song Xiaoshuang of course understood what Sima Yuru thought, according to the normal procedures of deep-sea diving, there is indeed not much time left for the two of them to stay on the bottom of the sea freely, and the remaining amount of residual gas in the cylinder can support staying on the bottom of the sea for a few minutes at most, and the remaining time has to be wasted in the process of slowly rising to the surface of the sea in a roundabout way, and it is a dead act for deep-sea diving divers who are more than 100 meters deep to rise rapidly. There is no ready-made hyperbaric oxygen tank on the sea surface for divers to carry out continuous decompression operations, and deep-sea diving operations are simply not possible without considering the amount of residual air.

No matter how strong Song Xiaoshuang's personal physical fitness is. It is also necessary to take into account Sima Yuru's actual diving state, deep diving is an extremely rigorous underwater operation, and it is easy to have problems if you do not follow the standard procedures.

Underwater diving is unable to speak freely, and can only use gestures to communicate with his companions. Song Xiaoshuang noticed that Sima Yuru looked at the diving watch on his wrist. Obviously reminding him that he had to hurry up, Song Xiaoshuang's head wearing a diving goggle nodded, and he quickly gestured to indicate that he had found a suspicious entrance and exit that could enter and exit the huge energy weapon device on the bottom of the sea, if it was not possible within a few minutes, the two of them would immediately evacuate the bottom of the sea and slowly rise to the surface, return to the fishing boat and return to the island to come back another day, after noticing that Sima Yuru really understood, Song Xiaoshuang took the lead and swam towards a coral reef, and he had found a suspicious entrance to the passage in and out of the energy weapon device.

Find the entrance to this passage hidden in the coral reefs. Song Xiaoshuang thought that he was still a little lucky, and at first released his spiritual power outside his body. It was shielded by the invisible energy shielding force field released to the surface of the device by the energy weapon device covering an area of at least one square kilometer, and even if it was used with all its might, it was impossible to let the spiritual power penetrate through the surface of the device and enter the deeper part of the device.

Song Xiaoshuang, who already has relevant experience in various energy shielding force fields, naturally understands that his spiritual power has been greatly restricted, and it is no longer realistic to find the hidden entrance and exit of the energy weapon device by means of spiritual power exploration, but it is not useless to release the spiritual power outside the body, at least Sima Yuru was a little reckless and wanted to brush off the sea sand and various dirt on the surface of the device, and directly touched the surface of the light gray device with his palm to try to figure out what material it was The dangerous intention was stopped by Song Xiaoshuang, Because the seemingly formless energy shielding force field from the surface of the energy weapon device clearly showed a dark blue mist-like energy form under Song Xiaoshuang's spiritual power exploration.

The energy shielding force field adheres to the surface of the device in the form of continuous release of dark blue mist-like energy, like an egg white, wrapping the entire huge device into the mist-like energy, probably because the energy weapon device that has been exposed in the coral reefs and sea sand and silt on the bottom of the sea has an area of more than one square kilometer, and the dark blue mist-like energy on the surface of the device does not look thick, at most ten millimeters thick.

Song Xiaoshuang thinks that this kind of dark blue mist-like energy under the inspection of mental power is not only a simple function of energy shielding force field, guessing that it is very likely to have a great lethal effect, when diving around the energy weapon device to find the entrance and exit channel, Song Xiaoshuang has always been very careful to avoid direct contact between the body and the foggy energy on the surface of the device, and found that Sima Yuru wanted to touch the appearance of the device directly, Song Xiaoshuang naturally had to stop it immediately, and as a result, he used a sad sea fish to do a testing experiment, The charred sea fish confirmed Song Xiaoshuang's own guess, the energy shielding force field can not only shield the exploration of various artificial and natural energy bands (spiritual power belongs to the embodiment of bioelectromagnetic waves with great energy effects, of course, it is also within a certain range of energy bands, just because the release of energy effects is special and not easy to be monitored by instruments, and there is still the possibility of being detected by ultra-sensitive instruments and equipment under laboratory conditions, Song Xiaoshuang is an exclusive data analyst of the Institute of Human Sciences, Nature has its own unique views on artificial and natural energy bands), and its own lethal properties are easily untouchable.

When Song Xiaoshuang and Sima Yuru spent a lot of time cruising around the huge energy device for the second time, Song Xiaoshuang first noticed that hundreds of tiger sharks had mysteriously disappeared into the dark seabed. The light gray energy weapon devices that had long since moved away from the reef had mysteriously disappeared as if they had strangely coalesced into an army of sharks.

Song Xiaoshuang already had a great grasp in his mind, guessing that the reason why the sharks gathered to besiege the divers and disappeared mysteriously. It is affected or controlled by unknown band sound waves, specifically infrasound waves of a certain frequency should be the culprit, because Song Xiaoshuang's mental power exploration range is also very limited, and can only detect the form of energy bands released by organisms or organism-like devices, and for the energy bands in the special frequency range of radio, ultrasound, and infrasound, they cannot intuitively show specific energy forms under the inspection of mental power, and can only be sensed in some narrow frequency ranges. Know how infrasound and ultrasound are released.

In this way, Song Xiaoshuang was pleased to find that the mist-like energy shielding force field on the surface of the energy weapon device showed signs of rapid dissipation. The dark blue mist energy in some areas was completely invisible, and Song Xiaoshuang immediately found that his spiritual power had been able to probe the deeper interior of the device through the "window" formed by the dissipation of these fog-like energies!

After some investigation, Song Xiaoshuang was mixed, worried that the material of the energy weapon device should be made of a very dense alloy, and Song Xiaoshuang did it with all his might. It can make the spiritual power penetrate through two airtight anti-radiation three-proof alloy doors that are overlapped with metal lead. The energy device used to explore the seabed can only be used to explore a radius of a few meters, and by probing Song Xiaoshuang, he clearly knows that the radius of a few meters still belongs to the solid shell of the device, and then the depth position can not be done with some specific structural spiritual power.

Compared with the huge energy device covering an area of more than one square kilometer, a solid alloy metal shell with a thickness of several meters should be extremely normal, of course, Song Xiaoshuang not only thinks that the alloy metal shell of the device is only a few meters thick, but speculates that it will be a solid alloy shell after a few meters, and the specific thickness of the shell is because the effect of spiritual power has reached the limit to form a non-inductive area of exploration.

Happily, Song Xiaoshuang finally relied on the exploration of spiritual power to find a hidden entrance and exit location of the energy weapon device in the "window" area where the energy shielding force field disappeared. This entrance and exit location is located in a secluded coral reef, a small area of sea sand and mud in the coral reef thicket. The whole presents a rough funnel shape, and the surrounding sea sand and sea mud are piled up with a thickness of more than several meters, and it is unknown what is below a few meters because it has exceeded the radius of Song Xiaoshuang's spiritual power exploration (Song Xiaoshuang's spiritual power exploration range is more than 90 meters in the air and in the water body, but the exploration distance of the earth and seabed strata is Song Xiaoshuang's weakness due to the influence of the geomagnetic field, and the maximum exploration depth will not exceed the radius of ten meters), In the center, there is an area of nearly five square meters of sea mud and sea sand less than one meter thick, and you can clearly detect an erected oval light gray alloy tubular structure hidden under the sea sand and sea mud, and the nearby sea sand and sea mud are tenaciously growing coral reefs, and sea fish leisurely cruising and feeding in the coral reefs.

At the top of the tubular structure, there is a thick and elliptical alloy cover plate of at least one and a half meters, which is used like a kettle stopper to block seawater from entering the tubular structure, and there are escalators below the cover plate that go deep along the tubular structure, and many light gray protrusions the size of an octopus sucker about two inches thick are densely packed in the tubular structure, and people with dense phobia will faint when they look at it, obviously this is a shaft-shaped passage into the energy weapon device!

So far, Song Xiaoshuang has already understood, and now it has been confirmed that Zhuge Hanyu and his people have estimated in advance how huge the energy weapon device and related components are dormant on the seabed, obviously the light gray reef-like energy weapon device covering an area of one square kilometer is only a part of the surface of the seabed, and there is a larger part that is deeply hidden under the seabed, just because the device has been on the seabed for too long, and it has been covered by sea sand, sea mud and gradually flourishing coral reefs for a long time. For a while, it was difficult to estimate the size of this energy weapon device.

After Song Xiaoshuang's more detailed mental exploration, Song Xiaoshuang noticed that because the thick alloy cover plate is like a plug that closely fits the entrance end of the channel, and the channel feels dry without a little moisture, Song Xiaoshuang speculated that when the alloy cover plate is opened, the dense protrusions in the channel will synchronously form an energy force field to isolate the invasion of seawater, and it is not very easy to really enter this channel, and it is necessary to overcome the energy force field that rejects the seawater. This is because the energy field is not currently active.

Song Xiaoshuang's plan was that if he couldn't think of forcibly breaking down the alloy cover plate with a thickness of more than one meter within a few minutes, he would not continue to stay on the bottom of the sea to consume the compressed air in the gas cylinder, dive to the surface of the sea and return to the island on the fishing boat to make calculations.

Just as Song Xiaoshuang was standing on the sea sand under the sea with his feet wearing duck fins, ready to hit the energy with his palms to "blow" away the sea sand that covered the cover plate of the shaft passage less than one meter thick, he and Sima Yuru both noticed that the nearby sea water was illuminated by multiple pillars of light, and there were no less than a dozen divers wearing gray and black diving suits and carrying compressed air bottles, carrying some equipment and approaching quickly!

More than a dozen sturdy divers attached to the sides of several underwater thrusters, grasped the grip of the underwater thrusters with one hand, and used the thrust formed by the propeller at the rear of the underwater thruster to stir the seawater, rushing into the sea water at a high speed like a swordfish, and in an instant, they had entered Song Xiaoshuang and Sima Yuru dozens of meters away, and then instantly reversed the underwater thruster propeller to slow down.

In the process of these divers approaching rapidly, Song Xiaoshuang signaled Sima Yuru not to act rashly, the spearguns carried by the two were difficult to form effective damage to these divers approaching at high speed, and when Song Xiaoshuang's mental power had already explored that the divers also included Zheng Hailing and Zhuge Hanyu, Song Xiaoshuang had already understood that the spearguns could not be used, Song Xiaoshuang was just a little surprised that he saw a familiar face among the approaching divers, the American girl who caused him a lot of trouble, Female Agent Adella of the Psychic Research Laboratory (To be continued.)
