Bai Fei and others were currently at an underwater depth of about 110 meters, and above their heads was the Xumizuo.
The average water depth in Manila Bay is 40 meters. If the seabed is compared to a field, Fortress No. 5 is like a radish buried in the ground, and the glass curtain wall above the seabed is like an exposed radish seedling.
But now, the carrot has been pulled away, leaving only a pit. The three members of the Renaissance Organization are equivalent to being in the lower middle of the pit.
Hun pointed to a few shadowy pillars further away, supporting the Xumizuo: "The so-called probe is a tool to help the Xumizuo stick to the continental shelf. It can be called a needle or a pillar. As far as I know, there should be thirteen installed under the Xumizuo. The probe, the thickest and strongest main needle is like the star position called Tianyuan in Go, it is in the center, we will find it if we look deep."
"Do you think the pipe that transports the divine mist is wrapped in the main needle?" Bai Fei turned on the night vision mode on her helmet, but she still couldn't see too far.
"Not only that, Bai Fei, I remember that you can't be too far away from the mouth of the well when your ability is activated, right?"
"Well, it can't be farther than a hundred meters."
"That is to say, if we want to collect the No. 5 Well, we have to go down to the metal hall at the bottom of the No. 5 Fortress."
Diego came up with a new idea: "Why can't the ability be activated at the bottom of the pit? Separated by the metal wall and four layers of ruins, the straight-line distance between the bottom of the pit and Well No. 5 should not be more than a hundred meters."
"Theoretically it's possible, but there are too many variables." Hun dismissed his proposal: "Bai Fei's ability will drain away her strength and concentration when activated. She will be particularly vulnerable during this period. It would be very uncomfortable to use her powers on the seabed. Safety."
"And there are hundreds of prisoners and soldiers below. It would be terrible if we caused a disturbance and were discovered. In the water, our combat power is ten thousand, not to mention that my superpower acts on the spirit and is ineffective on weapons. .”
"Compared to the success of the operation, Bai Fei's safety comes first, so this method is not advisable."
Bai Fei, who was repeatedly called out, was a little helpless: "Although it is true, it is really hurtful to call me so useless... I probably understand your plan, based on Mr. Diego's previous inference on the Dolphin III , there should be a group of prisoners descending from the Xumi constellation to the lowest level to resist the alien creatures that may emerge from the No. 5 well. Then we only need to find the way down, and we can achieve our goal."
"Hun, do you think there should be a vertical elevator installed at the main needle to transport prisoners?"
"That's right." Hun nodded: "Now it seems that this is the only way to get to the bottom. We have to sneak into the Xumizuo first and then find the elevator entrance. Pedro?"
"I'm here, Commander." In the Dolphin II, Pedro has been standing ready.
"I need the location of the entrance and exit of Xumizuo and the time it opens."
"clear."
Under the control of Pedro, a swimming fish approached the Sumeru constellation. These natural scouts will bring good news to everyone in the revival.
…………
Some readers may find it strange that the Fuxing trio must have consumed a lot of oxygen while swimming and talking. How many compressed air bottles did they bring?
The answer is: 12L.
There is a formula to calculate the usage time of compressed air: diving time = [cylinder volume (liters) * (inflation pressure - signal valve indication pressure)] / [gas consumption per minute at normal pressure * (1 + 0.1 * diving depth) *0.098]. So theoretically, a standard 12L cylinder can be used by divers for about an hour.
But actually, that's not right.
There is no absolute time limit for the service life of a cylinder, it is related to the diver's proficiency and diving depth.
If you are a novice who has just learned to dive, even at a water depth of 2-4 meters, you can use up a bottle of gas in less than half an hour. Because stress causes your breathing to be disordered, which consumes more oxygen.
Dive depth also directly affects gas consumption. For example, in a place with a water depth of 10 meters and a water depth of 20 meters, the amount of gas consumed is completely different. Because the deeper the water, the greater the pressure, and the gas is compressed.
At 20 meters underwater, a 12-liter cylinder with a pressure of 200 bar is actually enough for a diver in a relaxed state to use for more than an hour, but if the same diver is in a crazy state of exercise (for example, top Swimming, chasing underwater creatures or breathing heavily in anxiety), it is possible to drain a 12-liter cylinder filled to 200bar within 10 minutes.
It was obvious that the three members of the Renaissance Organization were definitely not in a relaxed state when diving. Their breathing began to become disordered when they activated their skills; and the three of them dived from a depth of more than 30 meters underwater in less than ten minutes. One hundred and ten meters underwater, although the super physical fitness of the esper can withstand the rising water pressure, logically speaking, the oxygen in the bottle should have been exhausted long ago.
Unless... their cylinders have another mystery.
From the appearance, the three cylinders are very ordinary 12L diving cylinders, but in fact, their internal volumes are much larger than that. The gas bottles and diving suits prepared by the revival organization for the recycling team have been blessed by a certain space-based ability user. Now these equipment have been magically transformed into something similar to Doraemon's dimensional pocket. The internal space is larger than the external space. What you see is much bigger. The compressed air stored in each cylinder can be conservatively estimated to be used by one person for twenty-four hours.
…………
The recovery team didn't wait long before they received instructions from Pedro. A group of soldiers guarding the prisoners below were coming up, possibly in shifts. Faint followed suit and used [Binding] again, leading Bai Fei and Diego to swim upright to the soldiers who were on guard.
What these soldiers are wearing is not a diving suit, but an individual mecha specially built by the Federal Weapons Research Institute to cope with the deep-sea environment. The mecha is equipped with concussion cannons on both palms, and underwater propulsion devices are installed on the back and soles of the feet. It is a very practical combat mecha. The only shortcoming is that the gas cylinders carried can only last two hours for soldiers to breathe. They cannot perform missions for a long time. They must return to Xumizuo soon to replace the gas cylinders.
A gate was raised at the waist of the Xumizuo. The Fuxing trio followed the soldiers and entered the interior of the Xumizuo smoothly. Once everyone enters, the gate will be closed immediately, and the drainage system will work to drain the indoor seawater out of the Xumizuo.
After the seawater was drained, a door opened quickly on the inside, and several logistics personnel walked in pushing a cart. There are gas bottles stacked on the pallet. After the logistics personnel complete the ventilation operation for these soldiers, the room will start to be filled with water and the gate will be opened again.
But this has nothing to do with Bai Fei and others. The three of them have already run out far away and reached the depths of Xumizuo.
Fainting in a corridor with no one and no surveillance, the ability was removed. This time the [Binding] was not activated for too long, so Bai Fei and Diego were able to accept it.
"We're already in, things below will be much easier to handle." Wu took off the obstructing diving helmet and gas cylinder: "Let's change our equipment first, then find a place to ambush, wait for someone to pass by, then strike, knock them out, and then take off their clothes. Put on a different disguise."
"OK."
"clear."
Diving equipment that is temporarily unused cannot be hidden anywhere. On the one hand, there is a possibility of being discovered; on the other hand, if some changes occur and they cannot return to the location where the equipment is hidden, the three people who lost the equipment will But the sky is not working and the earth and the earth are not responding.
It was impossible to carry out such cumbersome actions with helmets and air bottles. The leader of the revival arranged a better way for them: on the right side of each person's diving suit, there was a line extending from the ribs to the waist, about thirty centimeters long, and a zipper of unknown meaning.
Of course, this zipper is not a decoration, because the zipper is also a dimensional pocket of Doraemon, with helmets, gas bottles, and fins all stuffed into it.
"The tailor's use of spatial abilities is really unique." Although this was not the first time she saw the tailor's craftsmanship, Bai Fei was still impressed.
"So these diving suits and gas cylinders are the work of tailors?" Diego has only been a member of the Renaissance Organization for three years, but he has obviously heard of the tailor's name: "All the members of the organization's logistics department are very mysterious, let alone meeting them. I don’t even know their real names.”
"Don't tell me it's you, I don't know either." Hunkou curled his lips and said: "In the entire organization, the only one who knows all the information about the members of the Logistics Department is Chief Raphael."
"The three leaders of the Renaissance Organization, Leonardo da Vinci is in charge of weapon research and development and also serves as a diplomat; Michelangelo is in charge of training combatants, and the agents who perform missions around the world are his students, such as Bein Jafar; and Ra Phil controls the best logistics team in the world, and she arranges everything from diving suits to hurricanes."
"In my mind, Leader Raphael is omnipotent with his hands and eyes."
The faint words made Bai Fei nod like a chicken pecking at rice: "Raphael is the most charming woman I have ever seen."
"Oh."
Diego is still relatively new to the revival, and he has never met one of the leaders, Raphael. He can only rely on imagination to conjure up the image of an iceberg beauty standing at the pinnacle of power, overlooking all living beings.
The three of them stuffed unused diving equipment into their pockets and took out weapons from inside. In order to avoid alerting others when they take action, they use cold weapons.
What’s interesting is that the weapons of the three people all have regional characteristics.
Coma was born in Latin America, her hometown is the island of Cuba in the Antilles, and her weapon is a Colombian jungle machete. This is a kind of military machete that is very popular in South America. It is mainly used for jungle combat. It can not only open roads and march, but also can fight in close combat.
Diego is from Madrid County, that is, from Spain. He is a "two swordsman". In his right hand is a European rapier, luxurious and exquisite, as if it can be used for coronations and celebrations at any time; in his left hand is a Spanish left-handed sword, with a polished surface and two-thirds of the area painted with gorgeous patterns. And heavily gilded, it is truly a steel art treasure.
Bai Fei held a Han sword with a cold light in her hand. This is a six-sided dagger (Han swords are classified according to the length of the sword, and those with a length of about 50-70CM are short swords; classified according to the number of sides of the sword, they can be divided into four sides, six sides and eight sides). The blade is like autumn frost. No one doubts that this sword has the power to blow hair and break hair, and it can make a decisive blow.
This wasn't the end yet. Bai Fei's hands were still groping in her pockets. She quickly took out a... body armor and put it on silently.
"Today is no better than that time at No. 2 Well in Shanghai. That time you were protected by me, Ye, and Xia Yan. Three of the four masters came, but this time it's just me and the recruits." Xun comforted.
"I didn't say I wouldn't wear it. Isn't this just wearing it..."
"Okay." Hunxu waved it a few times and tried the machete: "Let's go and find the elevator to the bottom."
"This topic has been changed too harshly... Please apologize to me!"
