"The calculation is correct, start digging, and turn the power to the maximum!"
Miyamoto Shio gave the order, and the giant drill bit with a diameter of one meter and two began to work amidst the roar of the engine. The wet soil rolled up and everyone stared at that place nervously.
After about two minutes, the soil turned into muddy water, and a large amount of water spurted out.
"Those who are not wearing protective clothing should stay away!"
Miyamoto Shio reminded loudly that the temperature of the underground river here is very high, almost boiling. If there is no protection, it will cause extensive burns in an instant if it is splashed.
Lu Chen and the others stood not far away and watched this scene. They watched the originally turbid muddy water gradually turn into red, like a red dragon breaking out of hell into the human world. Water mist rose in the air, and the visibility in this area was extremely fast. reduce.
"Tsk, tsk, is the craftsmanship of your Sheqiba family reliable?"
Caesar looked at this scene and pointed at the special diving suit he was wearing.
"It may not be as good as the equipment department of the college, but please trust our technology."
Yuan Zhisheng said, as if to ease the serious atmosphere, he smiled and said: "At least we don't have a bomb function."
What they are currently wearing are polyacrylonitrile fiber fabrics and specially made wetsuits combined with a variety of advanced technologies. They can achieve basic heat insulation within half an hour and keep the interior below 50 degrees within an hour. They are the first of human technology. crystallization.
The water on the Akagui River that passes through Mount Fuji has been heated by ground fire and is almost boiling. Going down without any protective measures is undoubtedly courting death, so Caesar checked Lu Chen several times for fear that there would be any gaps in this guy's sloppy clothes.
"What are we waiting for?"
Lu Chen admired the wonderful scenery and asked questions.
"When the water pressure drops, Brother Lu, I think you should learn a little basic physics. It's not difficult. I can teach you when you return to the academy."
Chu Zihang explained on the side that the highest level of Chigui River is much beyond this point, but as time passes, the water flows to a certain extent and the pressure will decrease slightly.
"Haha, as long as Brother Chu is by my side, it will be fine."
Lu Chen laughed. He felt a little overwhelmed by learning such things.
"Would you like to take a photo first?"
Caesar suggested that the four of them were now wearing cool black diving suits, with knives hanging on each waist, looking like interstellar warriors in Star Wars.
Then Yuan Zhisheng, who was about to reiterate the task process again, was pulled into the team by Lu Chen. Caesar threw the camera to a staff member and motioned for a quick photo.
The staff member was stunned for a moment. Through the transparent mask, he could see the reluctant expression on the young master's face. He was hesitating whether to do this. How many fingers should he cut off to apologize for violating the young master's wishes
Chu Zihang couldn't say he advocated taking photos, but he didn't reject it either. Seeing that Brother Lu was already in place, he also carried Murasame to the team.
"Shoot."
In the end, Yuan Zhisheng spoke helplessly. He was almost fed up with these second-raters. This instant camera uses old-fashioned film technology and is heat-resistant and waterproof. It was originally intended for them to take some photos underground as useful information, but I didn’t expect that the first photo in it would actually be a photo of me and a few idiots.
Lu Chen put his hands on the shoulders of Caesar and Yuan Zhisheng, while Chu Zihang was next to Caesar. Even though he was wearing a diving suit, he stood like a solemn warrior.
Caesar and Lu Chen smiled happily, Yuan Zhisheng looked helpless, and Chu Zihang was expressionless.
"Click—"
The staff member pressed the shutter, and a photo of the four interstellar warriors was frozen. He quickly returned the camera to Caesar and ran away, fearing that the young master would find him to blame later.
At this time, the water pressure of the Akakigawa tributary began to weaken, and the water flow was diverted by the pre-dug channel of the Rock Flow Research Institute. Their mission was about to officially begin.
Yuan Zhisheng took the lead and walked to the entrance of the cave. He said that the water pressure had dropped, but in fact the speed of the water flowing up could still reach six kilometers per hour. However, this speed was completely bearable with their mixed-race physiques. With him and Lu Chen in front Open the way, and the pressure on Caesar and Chu Zihang will be much less.
"Young Master, I wish you good luck in martial arts!"
Wearing protective clothing, Miyamoto Shio walked up to Minamoto and said with a serious expression.
He rarely calls Minamoto Chisheng the Young Master, and most of the time calls him the head of the Genji family. However, this mission is full of dangers. Their Amaterasu will take the lead in diving. Looking at Minamoto Chisheng's firm steps, he also feels a little... Impressed by it.
"Master Miyamoto, I'll leave it to you."
Yuan Zhisheng nodded, and then motioned for Lu Chen and others to follow him. He stretched out his legs and stepped into the cave with red water. When his legs entered, even though the water was boiling, he felt as if he had stepped into the netherworld for a moment. The feeling is a chill that goes straight into the soul.
He calmed down and grasped the rope around his waist. This nanotechnology rope connected him and Lu Chen and the others, and was also connected to the winch on the ground. If there was any accident, they could quickly evacuate and surface through the rope.
In addition, the ropes were also connected to the lines on their diving suits, allowing four people to communicate. Under the interference of the magnetic field, the most primitive "wired telephone" was moved out.
"Set off!"
He said, and then jumped into the hole, and the red water rushing up was much less.
Lu Chen felt the pulling force from his waist and saw that Yuan Zhisheng had begun to dive hard on the rock wall. He smiled and said to Caesar and Chu Zihang: "How about walking?"
Then he also stepped into the rolling red water.
There was a dim red color in front of his eyes, and there was only the noise of water rushing around him. It was as if he had entered another world in an instant. With one step, he was cut off from the rest of the world, with only the light of Yuan Zhisheng's diving suit in front of him guiding him forward.
He held his hands on the rock wall and began to move down. After a short distance, he heard the sound of water entering again, which must be Caesar coming down.
"Oh, this kind of diving has a unique flavor."
Caesar admired in the four-person channel. The red breasts rose from the eyes with bubbles, like white lotuses blooming in the red hell. The sound of bubbles bursting in his ears was reminiscent of the evil ghosts in hell. wailing.
In a sense, they are indeed heading to hell.
"Yuan-kun, how far is it?"
Lu Chen asked Yuan Zhisheng who was in front.
"There's about thirty meters left."
Yuan Zhisheng replied, this tributary is 127 meters above the ground, and there is a water pressure difference of nearly 300 meters from the highest point. In terms of pressure, the pressure at the deepest point is unbearable even for professional divers. , but they are all excellent hybrids. This depth is completely acceptable and does not even affect long-term activities.
Of course, they have to leave before the heat resistance time of the wetsuit runs out, otherwise they will become boiled ducks.
The people who were diving behind stopped talking. As they got farther and farther from the ground, they all realized what they were doing.
"It's over."
As soon as Yuan Zhisheng finished speaking, Lu Chen felt the pulling force of the rope around his waist getting stronger. It took a few seconds to stabilize. It seemed that the water flow below was indeed very fast.
Lu Chen pulled out the red maple and inserted it into the rock wall, fixing his body, and then took down Caesar and Chu Zihang from above.
The water speed of this branch of the Akagi River is indeed very fast, about 20 kilometers per hour, which can be said to be extremely fierce.
Due to the buoyancy in the water, Yuan Zhisheng and Lu Chen, the two people with higher "body density" and stronger strength, were fine. Even Caesar, who had excellent water properties, could not find it without the help of Dickwedo who was inserted into the rock wall at this time. Stabilize your posture.
"Damn, why so fast?"
Caesar cursed. This was the first time that he, a master diver, felt an impact. Although he had expected it based on the previous eruption of water, the turbulence of the water below still exceeded his expectations.
"According to previous exploration, it is deduced that the target should be in the upper reaches. Time is limited. Let's start taking action."
Yuan Zhisheng opened his mouth in the channel. He inserted the spider into the rock crevice and walked upstream against the impact of the water flow.
Lu Chen and others lined up in a straight line, so that they could conserve their physical strength to the maximum extent. As for Yuan Zhisheng's physical strength, they were not too worried, as he was also a super hybrid.
"There seem to be creatures here."
Under the illumination of the cold light, the dim river water was as beautiful as a transparent gem. The visibility was limited, only about five or six meters, but it was enough for Lu Chen to see clearly what was under his feet.
There are some tiny creatures on the rock formations at your feet. The light shines through the red river water and reflects the gleaming light on them. These small creatures lie on the rock formations, motionless under the impact of the water flow. Their tiny hooks hang on the rock formations, just like It's like stepping on the earth.
"It's krill."
Chu Zihang said, and then popularized science for Brother Lu: "A long time ago, Mount Fuji was not what we see now. It has experienced several eruptions, and the accumulation of volcanic ash and cooled magma has formed thick rock layers. It has also been here It’s the surface. The volcanic rocks are rich in various minerals and nutrients, and there are smaller plankton or algae growing on the surface, and these krill feed on them.”
Lu Chen praised repeatedly after hearing this. He thought the underground was a dead and silent place, but he didn't expect that not only was there life alive, but it also formed a certain ecological circle.
These little creatures cling to the rock formations because their instincts engraved in their genes tell them that once they are washed away, they will be cut off from food and separated from their families.
But no matter it is any life, there will be times when it is exhausted and makes mistakes. In the face of a real torrent, sometimes no matter how tight you hold your hand, it will be washed away. Just like Lu Chen saw a few krill being swept away by the current. He picked it up and disappeared into the dim underground river in the blink of an eye.
"By the way... can this thing be eaten?"
Lu Chen curiously reached out and picked up a krill, placed it in front of his face and observed it.
Yuan Zhisheng, who was walking in front, also paused in his steps, thinking to himself, Mr. Lu, we are on a serious mission, and we are not really here to dive!
"I don't know, but it might be troublesome to peel off the shell and eat this kind of thing. I guess you won't find it satisfying, Brother Lu."
Caesar also picked up one, looked at it, and said.
"If Mr. Lu wants to eat aquatic products, I will treat you to the best ones after we go out."
Yuan Zhisheng's voice was a little helpless. They had walked upstream for more than fifty meters and found nothing unusual so far. With Lu Chen's interruption just now, the tension was reduced a lot.
"It's settled, I want the best cook here."
Lu Chen nodded. In fact, he did not have any technical tasks this time. Chu Zihang was responsible for recording coordinates and fixed-point blasting. Caesar was responsible for using Kamaita for small-scale exploration and taking pictures. Yuan Zhisheng was the plan maker and leader. He Lu Chen was probably a... security guard, preventing emergencies.
It was indeed a novel diving trip for him until something unexpected happened.
"There is indeed something abnormal here. After I came down, my Kamaita domain became smaller, as if it was being suppressed by some other domain."
Caesar's brows frowned slightly under his mask. Normally, he could detect a distance of several hundred meters, but now the area was only a few dozen meters wide. Although he had tried before coming down, he couldn't detect the underground, but he didn't expect to be suppressed so hard here.
Also, the Japanese branch is not without users of word spirits such as Kama Itachi and Snake, but in the end they settled on the "stupid method" of having a commissioner come down, which can only be said to be helpless.
"Will it be Gu Long's spiritual realm?"
Chu Zihang was slightly wary.
Caesar shook his head, "It's not like Kamaitachi didn't show any panic or anxiety. This feeling is a bit strange, and what he insists on saying is a bit like... getting lost."
"get lost?"
Gen Zhisheng, who was walking at the front, turned back. This branch should not be that complicated. In theory, it should be a straight line. In fact, they had never encountered any branches. How could Kamaita get lost
The spiritual products of Kamaitachi's words. If they get lost, it means that Caesar's spirit has been affected to some extent and his judgment has become inaccurate.
"It's interesting. There may be more than one big guy hiding here."
Caesar is not too worried, but is more interested in this exploration. He has always been confident. Moreover, there are two super hybrids opening the way in front. Even if the ancient dragon really revives, they will not be helpless.
There are many holes on the rock walls on both sides, which were left by the air bubbles in the magma before it cooled. After years of erosion, it has now become very smooth. The water flows through those holes, as if it brings some kind of wonder. The melody and the sound of Yuan Zhisheng's sword stabbing into the rock form a harmonious piece of music.
Traveling in the underground river was boring. After the initial novelty, several people stopped talking. At this time, they had gone upstream two hundred meters, and Yuan Zhisheng finally raised his hand to signal everyone to stop.
"Something's not right."
Yuan Zhisheng's expression was solemn and his delicate brows were furrowed.
Lu Chen also realized the problem. Even if the technology of the Japanese branch is not as good as that of the academy, it should still be the best in the world. Even if it cannot accurately locate the target, its assessment of the general range should not be wrong.
But now they have gone upstream for two hundred meters. Not to mention the ancient dragon, they haven't even seen any strange creatures. The only abnormality is that Caesar's speech and spiritual range seems to be further shortened.
This is not good news for them. In the dim underground river, the distance that the eyes can see is limited, and they must rely on Caesar, the bioradar.
