The entrance to the small space is located in the heart of the North American basin at depths of less than 6,000 meters. Pen & Fun & Pavilion www.biquge.info

What is the concept of more than 6,000 meters under the sea.

Without the help of anything, a normal person dives to a depth of about 10 meters, and some professional divers can dive 15 meters or even 20 meters (this is the limit).

One atmosphere has a pressure of about 1 kg/cm².

From the surface of the water, the pressure increases by one atmosphere for every 10 meters of downward movement.

From the surface of the water (one atmosphere) to 100 meters below the water (10 atmospheres above the surface of the water = 11 atmospheres) the pressure increases to 11 times.

The depth of the dive is directly proportional to the pressure in the water, the deeper the dive, the greater the pressure on the person, in addition, the change in water temperature, because the deeper the colder, but also consider the strength of your breathing.

In short, the depth of the dive is directly proportional to your own physical condition.

The world's highest record for naked diving is 20 meters.

When the water is 3 meters underwater, the human eardrum will produce a lot of pressure, when the human chest cavity is below 7 meters, the human chest cavity will be subject to a certain backlog, and when the internal organs of the person are below 15 meters, the internal organs will be subjected to greater pressure, and the blood vessels will expand and the pressure will be related to the blood part of the gas escaping.

Even if you dive in a wetsuit.

The AIDA-sanctioned freediving (wetsuit-wearing) world record is 281 meters, by Goran? ORAK was created on June 28, 2013 in Belgrade, Serbia.

That is, a normal person, even if he wears a special diving suit, it is impossible to dive 300 meters in the sea.

Although Zhang Long and the others are all strong, if they want to dive to the entrance of a small space with their own strength, it is difficult to dive 6,000 meters naked, even if they have a special ability to protect their bodies.

Only by wearing a super wetsuit made of high-tech can everyone safely dive more than 6,000 meters and reach the entrance of the small space.

After Zhang Long and his entourage entered the sea, they could still see the surrounding environment at the beginning, what sea fish, seaweed, corals and so on.

However, as the dive went deeper, the visibility around me became less and less, and soon it became dark and the temperature began to drop.

After that, everyone turned on the searchlight on the wetsuit on their heads, and then continued to dive towards the deep sea.

Around Zhang Long and the others, there were warriors from other countries and people with extraordinary abilities wearing various diving suits.

Under the vast sea, no one spoke, everyone was concentrating on diving, and at this time, even if the hostile forces encountered, they would refrain from the idea of making a move on the other side.

After all, this is in the deep sea, and fighting in the deep sea is a very dangerous thing, as long as the diving suit is damaged by the other party, even if it is just a small crack, it may endanger one's own life.

So everyone has a tacit understanding, at this time, no one dares to joke about their own lives, even S+-level powerhouses dare not kill hostile forces at this time.

In fact, Zhang Long and others don't need to wear diving suits.

As long as Zhang Longken takes out the Hunter Mecha Erlang God and the Blade Runner, everyone can reach the entrance of the small space in the blink of an eye, instead of diving slowly like in front of them.

It's just that the Hunter Mecha, a cutting-edge technology mecha that is at least more than 50 years ahead of this plane, if it is taken out, Zhang Long will definitely be targeted by the United States and Britain and other European and American countries.

Although Zhang Long is strong at present, he does not have the strength to confront a top power, especially a world hegemon-level country like the United States.

Who knows if Lao Mei has some other secret weapons secretly, in addition to the powerful navy that dominates the world, the powerful nuclear weapons that can destroy the earth several times, and the supernatural agency of S.H.I.E.L.D., which deters the entire earthly world.

Zhang Long didn't dare to take risks, when his own strength was not strong enough, boring development was the last word.

The group dived at a speed of 200 meters per minute, and it took half an hour to dive to the North American Basin, which is more than 6,000 meters deep.

"Your Excellency Zhang Long, this way."

Philip's voice came over the communicator.

At a depth of more than 6,000 meters, you can't see your fingers, and there are few marine creatures around you who can live in the deep sea of more than 6,000 meters.

Where the searchlight shines, except for their uninvited guests, all of them are seas, mountains and rocks, and from another angle, they are still mountains and rocks.

Small space has been discovered by human beings for hundreds of years, and in the past 100 years, the world's underground forces will gather in the Bermuda Triangle on October 1 every year, diving more than 6,000 meters to enter the small space to hunt for treasure.

Therefore, at the entrance of the small space, there is a mark.

It is a 10-meter-high nuclear sea lantern, which burns with nuclear energy, and was installed by S.H.I.E.L.D. in the 60s of the last century, which can illuminate the sea area within a radius of thousands of meters, which is very conspicuous.

Not only Philip and others saw it, but also the supernatural and martial artists of other countries.

"Go, go."

Zhang Long said, his legs swinged, and the whole person shot out like a swimming fish towards the sea lantern thousands of kilometers away.

Xia Mengmeng, Mochizuki Ruoxiang, Mu Wanqing and others followed.

Three minutes later.

Zhang Long and his entourage stopped in an open space 100 meters away from Hai Deng, waiting for the small space to open.

A group of underground forces in the world, centered on the sea lantern, are scattered in the sea area within a radius of 100 meters.

The underground forces in Europe are in league with each other, the terrestrial forces in the Americas are also clustered together, and other forces such as Southeast Asia, Japan, Korea, Oceania, and so on are also grouped together.

The same is naturally true of the forces in China.

Around Zhang Long and his entourage, there are underground forces in various regions and provinces and cities in China, Huaxia Heavenly Court, Shaolin Wudang, Emei Huashan...... In the underground world of Huaxia, the famous martial arts faction and the ability organizations are all here.

In addition, there are a number of top-notch, first-class second-rate families in China, among which the most famous are the four super families of Dongfang, Ouyang, Dugu and Ximen.

The four great families have been in the same breath and have married each other for thousands of years, you marry my daughter, I marry your daughter, and now, an alliance has been formed.

If you choose one of the four families and bring out one person, you can get related to the other three families.

Therefore, it is not surprising that the people of the four families stand together.

"What's the matter, Sister Big Breasts, did you see an acquaintance?"

Seeing Ouyang Ling's eyes looking directly at a group of people not far away, Zhang Long asked in a voice.

"Ouyang Qiu, I saw Ouyang Qiu!"

Ouyang Ling's voice was cold, and there was a taste of gnashing his teeth.

"Ouyang Qiu, Ouyang Qiu, the current family of the Ouyang family?!"

Zhang Long said that Zhang Long naturally knew about the grievances between the big-breasted sister and Ouyang Qiu.

After all, it was this Ouyang Qiu who wiped out the entire Ouyang family of the big-breasted sister, her grandfather, her father and mother, all died because of this Ouyang Qiu.

"Yes, it's the old thief."

Ouyang Ling said coldly.

"It's better to choose a day than to hit the day, since you have met this Ouyang Qiu, the small space will be opened later, after you enter, you can find an opportunity to kill him, with your current strength, it shouldn't be difficult to kill him."

Zhang Long said.

"Hmm."

Ouyang Ling nodded, a cold glint flashing in his eyes.
