No toads have been found in the huge underground sea, but it does not mean that there are no giant toads in this sea. No living blood creepers have been found in the large blood cedar forest, but it cannot be said that there are no blood creepers here. There was silence around the subterranean sea, and it was likely that danger was brewing.

It's not safe here, Ma Qian has a premonition that danger will happen, looking around, it's dark, except for the vast water, he can only hear the sound of water crashing on the shore, and he can't even hear the whining of any insects.

Go back to the beach and sit down, do you find the cave in the boar valley and leave here, or do you have to wait for news from Huaxiong and Huaxin and others?

After discussing with the other three, Ma Qian decided to wait a little longer and wait until there was a shortage of food before leaving. Besides, Brother Qiang's current physical condition can't afford to toss, let him recuperate first, and then make plans.

Continue to rest on the beach, repeatedly climb in the hole, being endlessly chased by blood crawlers, giant toads, and yellow-faced people, they have long been exhausted, and everyone has different degrees of injuries on their bodies. The few hours of rest just now were just a drop in the bucket. It's no longer safe on the beach, so leave one person to stand guard before resting, the first one is Zhao Chiang Mai.

When Ma Qian and the others were asleep, Zhao Qingmai saw a figure flashing on the other side of the Toad River, and he couldn't see clearly because he was too far away. The beach where Ma Qian and the others rested was near the left bank of the Toad River, and the position where the figure flashed just now was on the right bank of the river, and because it was separated by a river, the danger was not imminent.

Zhao Qingmai hesitated, not knowing whether to wake up Ma Qian, Zhao Baixiong and the others, after all, the brothers had only slept for more than an hour. Just as he hesitated, something happened without warning.

First of all, there was a loud noise, "snort", this sound sounded around him, and the entire underground sea (lake) shook, this kind of earthquake-like shaking was very violent, and Ma Qian and others also woke up violently.

A vision appeared in the underground sea, and the place where the sound came from was near the island in front of the mouth of the Toad River. Just 50 meters into the sea from the rocky island, a huge blister rose on the water. The size of the bubble is beyond imagination, this large bubble is 100 meters in diameter, and it rises from the sea like a space crystal ball, and bursts violently above the dome above the underground sea.

This time it was closer, and the sound of "snorting" was actually separated, first the shaking of the ground, followed by the sound of "swish", the blisters rose on the surface of the sea, gradually became larger, and burst open after reaching the dome, and then let out a dull "gwitching" sound. There is only four meters of space between the water and the dome, and the sound has nowhere to travel, and after being heard at close range, the sound is deafening. Everyone's eardrums were buzzing.

The large blisters that burst open, the water splashed, sprayed hundreds of meters away, splashing several people all over the water. The temperature of this water is very high, much higher than the temperature of the water in the underground sea, and the hot springs in the underground sea are only twenty or thirty degrees, and the temperature of the water spray that has just been sprayed on everyone should be sixty or seventy degrees, which is very hot.

The vibrations of the ground continued, and the waves rushed in, and several people quickly retreated.

What's the situation, could this be the origin of the toad cry in Toad Mountain? What is this huge blister rising from the surface of the sea, could it be a super giant toad inhaling?

Several people shot their flashlights at the surface of the water, staring at the surface of the water with doubt. With a "whoosh", another huge bubble bubbled up against the seawater. The magnificence of the spectacle is truly indescribable, not the devastating nature of the atomic bombing, but an incomparable beauty. The sound was also grandiose, and the entire underground space reverberated with this roar.

The bubbles burst, and a huge curtain of water sprayed in the underground space, and the very hot bubbles filled the entire underground space with steam. It's such a spectacle that I never dreamed of being in the middle of a mountain and a sea of mountains, where huge bubbles were blown up by something under the water, and they swelled so much that they might have grown even bigger if they hadn't reached the rocks at the top of the dome. As soon as it touched the rock, the bubble burst open, forming a water zero that enveloped the entire surrounding space.

The bubbles rise one by one, and then burst one by one, not to see it with your own eyes, it is hard to imagine that in the underground space of Changbai Mountain in China, there is such a cosmic wonder, and the colorful large water bubbles show infinite life force.

Ma Qian, Lao Niu and the others kept retreating, and their bodies were drenched with hot water. "What the hell is this, an earthquake or an underwater bomb?" Zhao Baixiong's face was surprised.

"This may be the unique geography of this place, the water in this bubble is much higher than the usual water in the sea, obviously not the raw water in this underground sea, I guess there is a volcano underground, the volcano is regularly active, spewing out hot water to form a large bubble. But one thing that is not clear is explained, if it is regular volcanic activity, it should be a huge column of water ejecting out, how can it form huge bubbles and gush out of the water? Ma Qian was also at a loss.

The blisters gushed and exploded until the sixtieth time. After 60 huge hot water balls with a diameter of more than 100 meters burst open, the sea surface was hot, and the water was obviously nearly ten degrees higher than just now.

Several people looked at the sea, and at the place where the blister was bubbling just now, there was a huge column of water nearly 2 meters high bubbling upward, and the amount of heat was very large.

This is an eye of the sea, and blisters come out of this eye, and then hot water comes out of the bottom of the sea, and there is either a large hole or a crater under this eye.

Lao Niu looked at the surface of the water and slammed his head, "I know what's going on, there may be another layer of sea below this underground sea, and the two seas are blocked by a layer of rocks." The two seas are connected by only one sea eye, which is the place where the water bubbles just now. The underground layer may be close to the crater and the water temperature is very high, while the water temperature of this sea we see is low. Due to the special geological structure and air pressure of this underground space, the main reason is that the sea above is much larger than the sea below, and the water pressure is large, so the hot water below cannot be exchanged upward. And every seven or eight hours, when the temperature in the sea below and the upward counterpressure reach the limit, the gas under the pressure moves upward, and bubbles bubble upward, exchanging with the cold water above in this form. This geological phenomenon is carried out on time, which is why we have heard this sound many times. ”

"Myanmar boy, I'm convinced of you, you can think of this, when we find Huaxiong, we must use diving equipment to go into the water to see if there is really a magical sea under the sea." Zhao Baixiong also felt that Lao Niu's analysis was reasonable, and looked at Zhao Qingmai and Ma Qian, and the two of them also nodded in agreement, and even the weak Brother Qiang also said that this reasoning was more reasonable.

An hour ago, if a few people had left this underground sea, it would not have been possible to see such a wonderful and shocking spectacle, and it may never be possible to explain that the huge toad cry of Toad Mountain originally came from the underground sea in this mountain.

What a mysterious space this is, the interior of the mountain forms such a large body of water, although it is just a lake, but everyone still likes to call it a sea, because this hot spring sea is so rare, and in this black rumbling underground, the distance of light is limited, it is already wide like a sea.

It's not just a big place, there are so many holes, huge rivers, bleeding cedar trees, and this huge bubble of hot water. It's so strange, this mysterious space is filled with too many wonders, too many dangers, and too many incredible. A few people standing on the shore even forgot that they had followed Ikao to find the Japanese legacy. If it weren't for the dangerous experience of nine deaths, some people would have called this act a fantastical trip.
