Crane's Ark of Tomorrow Daily

After three days of preparation, they finally completed all the preparations before launching into the water, equipped the power system for everyone's protective clothing, and the oxygen generation module dedicated to underwater.

For this reason, each of them carried more equipment than before.

In fact, it is a very troublesome thing to produce oxygen underwater. Although the air in the underground environment is very thin, it is not completely absent. It only needs to go through a few simple filtration processes to obtain enough oxygen for human breathing.

But if the environment is placed in water, then the situation will become completely different.

It is true that electrolyzed water can move oxygen, but the problem is that electrolyzed water produces not only oxygen, but also hydrogen. When the two gases are mixed, it is very easy to explode.

Moreover, it is air that can be breathed by humans, not oxygen.

If the oxygen concentration is too high, it will be counterproductive. The high concentration of oxygen is inhaled into the body, generating excessive oxygen free radicals, attacking and killing healthy cells in the body, and affecting multiple organs in the body such as the lungs, brain, and eyes.

What's more, what they are going to dive into next is 'sea water', not ordinary fresh water.

After seawater is electrolyzed, not only hydrogen and oxygen are produced, but also highly toxic chlorine gas is produced. For these reasons, without specially customized equipment, the method of producing oxygen by electrolyzing water is simply not feasible.

Fortunately, Rhode Island's engineering department is very capable and perfectly met all of Amiya's requirements.After two days of testing, they can stay underwater all the time without worrying about the lack of oxygen, except that it is troublesome to replace and clean the electrolytic tank from time to time.

So, after enough preparations, at night, they finally officially started to explore the ruins.

"Greythroat, did the sensor detect anything abnormal?" Amiya asked.

During these few days, UNIVE-02 was completely in a state of non-stop work.Under the condition that everyone is on duty in turn, once UNIVE-02 is fully charged, it will be thrown underwater immediately to continue the task of exploring and arranging buoys.

After several round trips, the basic condition of the main waterway has been ascertained. Along the way, UNIVE-02 also left countless buoy sensors, bringing 80.00% of the main road leading to the ruins under the control of Rhodes Island.

For the remaining part, UNIVE-02 cannot reach that far due to limited battery life.They can only go to that area by themselves to investigate the situation there.

Hearing Amiya's question, Gray Throat checked on the console, then shook his head, "All the sensors are working normally, and nothing abnormal was found."

As Amiya said before, the appearance of the catastrophe was completely accidental. The data from the sensors in the past few days showed that there was no sign of any life activity underwater at all.

If it weren't for the slight movement of water that could be detected, they would have wondered if there was a pool of stagnant water below.

Gray Throat's answer dispelled the last worry in Amiya's heart, and now there was nothing that could stop them from moving forward.

"... Let's start now." Amiya said after taking a deep breath.

After Amiya gave the order, the operators jumped into the water one after another, but compared with before, their formation changed slightly.

Huang and ACE, who were supposed to be at the forefront, were placed at the end of the team at this time, but now they are at the forefront, Rosemary and Amiya, who should be protected the most.

Under the effect of Rosemary's Origin Stone skills, the four alloy giant swords combined into a huge shield, blocking in front of the two of them.

This is also a helpless move when there is no better solution.

The equipment of Huang and ACE is the heaviest in the team. If they are allowed to walk at the front of the team, the turbulence caused by their advancement will seriously affect the people behind them and disturb their balance.

In desperation, they could only let the lighter Rosemary and Amiya take the lead, but with the existence of a monitoring network composed of buoy sensors, even if they were allowed to take the lead, they would not encounter any danger.

"Ahem, test test, can everyone hear my voice?"

Not long after everyone entered the water, Amiya's voice came from the speaker next to her ear, but it sounded a little distorted, and it was a little different from her own voice.

After confirming that they heard Amiya's voice, everyone expressed their affirmation in the communication channel.

Under water, as long as it does not exceed a certain distance, radio communication equipment can still be used normally.In the case of a relatively compact formation, the effect of establishing a communication channel with radio is not bad.

"It seems that there is no problem with the communication..." Amiya exhaled and said, "Please go ahead and remember, no matter what happens, don't leave the team without authorization."

The moment she entered the water, Amiya felt her heart beating violently, and a strong uneasiness poured into her consciousness along the blood connection. The inheritance from the Sarkaz clan was warning her, This journey will definitely not be as smooth as she imagined.

Amiya can only force herself to calm down, so as not to let her inner anxiety affect other people in the team.

"If, I mean, if something happens and you accidentally leave the team, you must follow the direction indicated by the buoy, and you must not run around."

In this pitch-black waters, the searchlights equipped on them can only illuminate a distance of less than ten meters ahead. In the darkness farther away, there is an endless green light point that guides them. the way forward.

This is another reason for their buoys.

In the whole team, only Amiya kept the route firmly in her mind. If the route was not marked, in case someone accidentally left the team, in the huge maze of the infinite corridor, it would be It is absolutely impossible to find a way out.

In fact, all the people who disappeared in the infinite corridor ended up starving to death here because they couldn't find a way out.

Everyone moved forward slowly in the direction guided by the buoys. This time Li Ke was in the middle of the team, with Huang and ACE behind him.

The propeller provided by Rhodes Island perfectly solved Li Ke's problem of not being able to swim. He didn't need to do anything, as long as he tightened his body and didn't move around, the propeller installed behind the protective suit would push him forward. An occasional tweak of direction is fine.

After advancing in the sea for about an hour, they finally came to the fork where UNIVE-02 entered by mistake.

When passing the fork in the road, Li Ke still looked inside curiously, but of course, he didn't see anything.

The deep darkness in the passage is like a huge vortex, swallowing everything silently. After taking a second look, Li Ke quickly retracted his gaze... staring at it would make him feel slightly dizzy, and It was as if consciousness was about to be swallowed by that darkness.

Everyone didn't make any stops, and continued to move forward in the direction guided by the buoy.

Taking the forked road just now as the dividing line, the surrounding scenery has undergone obvious changes. The more you continue to move forward, the more dense the cracks appear on the passage wall, and there is a possibility of breaking at any time. disturbed.

After advancing for an unknown amount of time in an atmosphere of silence, finally, the buoys guiding their direction disappeared... This is the limit distance that UNIVE-02 can reach.

However, they were already prepared for this. After a little identification of the direction in front of them, Amiya led the team to move on, and ACE, who was at the end of the line, also opened his backpack, took out a few buoys from it, threw behind.

According to what Amiya said, there was not much distance left, and the buoys they carried with them were enough to cover the last distance.

It's just... At this time when these things are being done, no one still speaks.

Finally, someone couldn't help it anymore, and Huang's carefree voice sounded in the communication channel, "I said, this place won't collapse suddenly, right? This looks very dangerous."
