Thinking of the explosion, Han Da'er knew that it must be those Oriental devils who were attacked by giant earthworms on the black earth. That black soil was very vast, and although there were only two or three giant earthworms fighting with Han Daring and the others, they didn't know how many of these giant insects were hidden under this black soil.

Han Daring was originally happy in his heart, and said in his heart, although there are many of these Oriental devils and they are all armed, but with the giant earthworms in the black soil, they have lost most of their money. But when I heard the deafening explosion just now, even everyone's feet trembled, and their hearts were not only worried.

These Oriental devils, in addition to heavy fire weapons, are likely to also bring explosive grenades and other explosive weapons, although the underground world where everyone is now is vast, but after all, it is a huge underground space, if they blow up indiscriminately, it will very likely cause the collapse of the underground space, and then they will inevitably be buried alive underground and become a ghost.

As soon as I thought of this, I suddenly heard a burst of gunshots, coming from afar. Since everyone was in the stone building of the chimney race, the sound only came from the top of the stone building, so the sound was inevitably thick and muffled, but Han Daring and the others could also judge with experience that the sound of light machine guns at this time.

The white beetle encountered on the cableway bridge just now, Han Da'er's Lumo knife, and the red and white double cherry short knife were all hidden close to him, but the guns in the hands of others were all lost in the chaos, and only Wang Weihan's pocket pistol was still hidden in his arms.

Immediately afterwards, there were constant gunshots outside, presumably the Oriental devil and the giant earthworm were fighting, and the two sides were at loggerheads.

Oriental devils have a ruthless spirit in their bones, no matter how strong the enemy is, they don't know how to give in when they are strong.

These guys are ruthless, and they even poke themselves, but they have a bit of a Tianjin gangster's taste, but the gangsters are for Yang Wei and for food. This little devil is not for anything else, he stabs himself when he loses a fight, and he stabs himself when he loses a war, but he doesn't know that victory or defeat is a common thing in soldiers, and he doesn't understand such a simple reason on his face, and he also turns this into a glorious katana spirit, which is simply stupid!

Although Han Daring is also a Ning species, in order to save people, or to eradicate rape and eliminate evil, or even for the sake of the country's carelessness, he can resolutely give up his life, but such a stupid act of committing suicide after losing a fight is categorically disagreeable!

Don't look at the giant earthworm in the black soil is a fierce beast, but even if you attack the Oriental devil, you can bite the dog's temper, I'm afraid the beast can't stop this group of crazy people!

From this point of view, it won't take long for them to catch up, although Han Da'er is a master of art and bold, but now there is a shortage of firearms in everyone's hands, and relying on the cold weapons in his hands alone, there is no chance of winning against so many people at once.

Stopping now is tantamount to sitting still, and they must quickly find their way forward, hoping that they will either be trapped in the maze, or meet the gang of Sanyang Sect guys in front of them. Since these two groups of people are not acting together, they must have their own ghosts, and it is inevitable that there will be a fierce battle when the two groups meet.

At this time, everyone had already looked at the entire stone building. In addition to the empty pond stone eggs in the middle of the stone building, there are only some glowing spars, and on the eight inner walls, except for the huge circular recesses on two walls, the inner yin is engraved with the Sanyang Sect emblem, and there is no exit.

Fan Tong pushed hard towards the circular concave on the wall, and then raised his fist to the flat bottom of the circular concave, and hammered it a few times, only to feel that the concave flat bottom did not move at all, but it was not a stone door that could be pushed open.

Fan Channel:

"It's a big chimney at all, and there's no way out! We'll have to go up and figure it out again! ”

Wang Weihan coughed and said:

"Impossible! Ahem...... Since this is not an execution ground, it is also a sacrificial ground...... Ahem...... There must be a way out, otherwise how did these prisoners get here? Ahem...... And how did the soldiers who were in charge of escorting them get back? ”

Han Daring said:

"Outside this stone building is a rocky beach, and further on the platform is the wide underground river that I saw that day, I think those escorts in ancient times should have crossed the river from the waterway!"

As he spoke, he continued to look around the stone building stratum.

Due to the volatilization of the acid pool in the stone building for hundreds of thousands of years, the entire inner wall of the stone building is smoked black, although there is a luminous spar illumination, but it also needs to be illuminated by direct flashlight to see the wall clearly. The crowd groped around, hoping to find a secret door or a door opening stone or something like that.

Han Daring touched the huge circular concave on the wall again, he pushed hard, and the concave circle of the flat bottom really didn't move. He examined the edge of the concave edge carefully, and then scraped off some of the stone chips on the edge with a short shovel, and found some gaps in the edge.

The acidic erosion over the years has loosened the inner wall of the stone building, and many stone chips have blocked the concave circular gaps, so it looks like a whole. On the concave circle of this flat bottom, in addition to the emblem of the Sanyang Sect, there are three circles in the middle, each with a circular groove.

Han Daring put his hands on the groove, his body was not measured, and he found that his position was just in line with the action of the person leaning sideways and holding his hands against the wall, and his mind moved, and instead of pushing forward, he tried to push the flat bottom of the circular concave to one side.

He exerted a little force, but felt that the concave round flat bottom actually trembled slightly, so he took a breath and poured his arms into his arms, and vigorously rolled the round flat bottom to the side, only to hear a series of "Kerala" sounds, but the round flat bottom rolled slightly to the side, revealing a crescent-shaped gap.

It turned out that this round and concave flat bottom was a stone door that rolled to the side. The round stone door is inlaid with metal rails around the perimeter, and there are grooves under the door that roll the tracks, so that if you push hard to one side, the heavy round stone door can be rolled to the side.

Seeing this, everyone on the side also hurriedly stepped forward to help push, but there is no tentacle force on the surface of the round flat bottom, only the center of the three circles carved on the flat bottom, each with a circular pit, just to start the force, and with the flat bottom rolling, the three pits can just alternately hand, which is very convenient.

The stone door has not been opened for a long time, and the edge of the stone door is blocked by earth, stone and sediment, and because of the volatilization and corrosion of the internal acid, the metal track is corroded and rusted and stuck in the groove, so it needs to be pushed hard by Han Da'er, otherwise just one person needs to press the pit with both hands and push it alternately, and the stone door will easily open in response.

At this time, the stone door opens, revealing a circular doorway. The light from outside shone in, and everyone stepped out, but their feet stepped on the icy river with a "bang". I felt that the water under my feet was not slow, but the river was extremely cold and biting.

As far as the eye can see, there is a wide underground river, which is right in front of everyone's eyes. The width of this underground river is always seven or eight hundred meters, and it is even half wider than the widest part, but the river is not very turbulent, and if it is not for the flow of the waves, it is mistaken to think that the river is stationary at all. There is also a pale blue oil on the surface of the river, as if there is a blue oil film floating, and I don't know if it is the blue light I saw on the platform.

Not far in front of them was a huge piece of driftwood, floating on the surface of the river, only slightly undulating with the current, but it seemed to be fixed in place, fixed in place, and not drifting with the current.

Everyone went out of the doorway, looked to both sides, dozens of meters behind the slope is the river beach on both sides, the river beach is not muddy, all are some sharp and sharp stones composed of rocky beach. The place where everyone is now is already some distance from the river beach, but standing in the water, the river is only below the surface of the feet, not even the ankles.

Han Daring leaned over and touched the river water under his feet, measured it horizontally in the water, and then said:

"We seem to be standing on an artificially built stone trestle bridge, but the river has risen shallowly and has not passed the first floor of the trestle!"

At this time, everyone's feet were only soaked in the river for a while, and although they were wearing hiking boots, they also felt a cold air from the soles of their feet to the top door, and they couldn't help but shiver all over. The person closest to the door of the stone building had already jumped back into the doorway.

Mei Ruohong Road:

"This underground river is so cold that we only stand in the shallow water for a while, and our bodies are like freezing, and we can't cross the river without boats!"

As she spoke, her lips turned white with cold, and she hurried back into the doorway.

Han Daringer has been practicing martial arts for many years, and although he has the internal qi of the mixed yuan to protect himself, he has stood in the river for a long time, and he also feels that it is cold and abnormal.

He saw a huge piece of driftwood in the distance, so he tested the depth of the water with a short shovel, and walked quickly to check it. I saw that this driftwood was a thick trunk of four or five people hugging each other, and I didn't know what kind of tree was cut down, the texture of the tree was thick and white, but the outer layer was dark bark.

The driftwood has been hollowed out in the middle, and can accommodate seven or eight people to stand, but it is a small boat, but the boat has no rudder, no oars, and no mast sails, but it does not know how to control it.

On either side of the driftwood are two thin slabs as long as the length of the tree, attached to the water, as if there were two wings on either side of the tree, which seemed to be used to maintain the balance of the boat.

The wooden boat near the stern of the stone trestle was inlaid with a hideous human face, the human face was condensed and angry, and the whole face was hemispherically protruding, not made of metal, but like a stone carving.

Han Daring saw that the nose on this person's face was raised high, as if it was like a handle, and on the top of the person's face, there seemed to be something like a hinge, so he reached out to hold the nose of the human face and lifted it up forcefully.

Unexpectedly, the face of this hemisphere could be lifted, revealing a jet-black ball inside.

At this moment, he suddenly felt someone push him, and his body involuntarily moved towards the ball. He hurriedly stood with the stake, and looked behind him, but the rest of the people were still standing far away in the door of the stone building, and there was no one behind them.

Suddenly, he felt his waist loosen, and the shovel and pickaxe stuck in his waist flew towards the jet-black ball at the same time, and all the "dang" sounds stuck to the surface of the ball.

At the same time, the wooden boat suddenly moved on its own, and the hull of the boat twisted violently, and it crossed the river longitudinally, and the bow of the boat went straight to the other side of the river, and suddenly began to float away on its own accord.

Seeing this, Han Daring hurriedly reached out and grabbed the face statue, and stopped the wooden boat hard, he wanted to buckle the stone carved human face, but the ball was still tightly attached to the short shovel and the mountaineering pickaxe, and the stone carved human face could no longer be buckled by these two things, and the wooden boat kept trying to move forward.

Han Daring knew that the ball was a huge magnet, but he didn't know how the wooden boat was slowly driving, so he hurriedly reached out and pressed down on the stone carving face, while tearing the short shovel off the magnetic ball.

Unexpectedly, the suction of this magnetic ball was very strong, and with Han Da'er's strength, he couldn't tear off the shovel, but because he was carrying many metal weapons on his body, his body was also slowly attracted to the magnetic ball.

Seeing that the wooden boat was about to leave the trestle, Han Daring struggled to pull the hull of the boat, only to feel that the force of the hull was huge, and he tried his best, but he could only barely pull it, so he hurriedly shouted to the others:

"It's a boat, come here! Otherwise, the ship will drift away! Fast! ”

Everyone was stunned when they saw Han Daring holding the driftwood, as if they were wrestling with the driftwood again, and when they heard him shouting, they reacted and rushed to his side, and when they saw that the driftwood was really a wooden boat, they jumped on the wooden boat one by one.

It's just that the moment everyone jumped into the boat, the stern magnetic ball couldn't help but jingle for a while, and many people had a short shovel and pickaxe in their hands that were unstable, and they all flew out of their hands and were attached to the magnetic ball.

Han Daring saw that the last Li Huan also jumped into the boat, so he let go and jumped onto the wooden boat.

As soon as he let go, the wooden boat rushed forward, and it was already floating towards the center of the river!

The boat went straight across the river, at first at a very fast speed, parting the river and rushing straight forward, but when it reached a quarter of the width of the river, it slowed down, but it did not stop, and continued to sail slowly towards the opposite bank.

When everyone saw that this wooden boat did not need to swing the oars, let alone sail and rudder, and slowly crossed the river on its own without any maneuvering, they were very surprised, and they couldn't help but look around the hull.

Han Daring and a group of seven people, standing in the boat did not feel how crowded, although everyone looked around to check the hull, but the two sides of the hull of the boat, so that the hull of the boat in the river but not how undulating and shaking, plus the slow flow of the river, so it seems very stable.

Everyone was blocked by the hull of the boat in the boat, and the gold and iron artifacts on their bodies were no longer attracted by the stern magnetic ball. Han Daring said:

"I think just now under the stone trestle, there must also be a magnet like something, when the stern magnetic ball is blocked by the stone carved face, the body will not be affected by magnetic mutual repulsion, once the face statue is lifted, the stern magnetic ball, it will have the same polar mutual exclusion effect with the trestle magnet, and the pier will be quickly pushed away from the trestle!"

Ye Ling asked:

"Is the magnetism of the trestle so strong that it can keep talking about this wooden boat pushing to the other side?"

Mei Ruohong Road:

"I think there should be some two rows of magnets with opposite poles at the bottom of the river, and this wooden boat should be equipped with a paddle inlaid with magnets, and the magnetic force repels and attracts, and drives the oars alternately, so that the boat can move forward slowly."

By this time, the wooden boat had slowly sailed across the middle of the river and headed towards the opposite bank.

Han Daring looked at the opposite bank, and saw that the opposite bank was a sandy river beach, and further into the distance, it was dark, like a wood, and like a large bush, but there was a trace of smoke and dust rising from it, and it was hazy and unclear.

Chen Feiyang sat on the side, dumbfounded, and didn't say a word.

Han Daring felt that since he got on the ropeway bridge, Chen Feiyang had been groggy, and he didn't know if there was anything wrong with him being injured, so he patted him on the shoulder and asked:

"Dumbo! Are you alright, are you hurt! ”

Chen Feiyang didn't answer, just shook his head.

Wang Weihan stood and looked at the river for a while, and saw that this underground river was not only wide, but also very long, and he couldn't see the end at a glance, and an underground river had completely blocked the black soil, labyrinths, towers and stone towers.

Fan Tong felt exhausted, sat on the boat, held the wooden boat in his hand, sighed and said:

"I think this ancient man is much smarter than us, if there is such a thing, whoever crosses the river will use it as a ferry!"

Mei Ruohong Road:

"This principle is easy to say, but it is difficult to do, in case one or two of the magnets at the bottom of the river are not in the right position, the ship may sink at any time, or simply be torn apart by magnetic force!"

Fan Tong said busily:

"Stop, don't you know that you can't say you can't sink by boat? In case ......"

Suddenly, the wooden boat rattled and "Kara", and a hole was cracked in the middle, as if two forces were about to tear the wooden boat in half!

Fan Tong cried out with a sad face:

"Mom! Good spirits do not work bad! If you're afraid, come here......"

Without waiting for everyone to react, they only heard a crisp sound of "click", and the whole wooden boat disintegrated from the middle when it boarded, and the hull of the boat immediately fell apart......
