Chapter 1231： Super equipment

A 20-liter bottle of oxygen can provide air supply for more than an hour and a half at a depth of about ten meters, while the oxygen bottle carried by Shi Lei can provide a full supply of air for about seven hours.

In addition, the oxygen masks used by Shi Lei are also brand-new technology products. Even if they do not carry oxygen bottles on their bodies, the masks can be used for more than four hours in the depth of ten to fifteen meters in seawater.

This oxygen mask can extract oxygen from the seawater and provide it to divers. Its seawater filtration system is so fine that even water molecules cannot pass through, only oxygen molecules can enter and exit freely. effect.

The oxygen mask is powered by a small plastic battery. Although small, it is enough to support the oxygen mask for four to five hours of use.

Of course, these are real luxury products. Although such oxygen masks have been sold on the market, those civilian products generally can only provide divers with about forty minutes of oxygen supply.

The gap between them is by no means a simple five or six times the price can make up.

The price of a set of ordinary oxygen masks on the market ranges from more than US $ 1,000 to US $ 5,000, but Shi Lei ’s oxygen mask, which can guarantee at least four hours of oxygen supply, costs nearly 100,000 US dollars.

Coupled with that diving suit, Shi Lei paid more than half a million dollars for this trip to the island alone.

This doesn't even include the price of replaceable equipment. Shi Lei even prepared a replacement value of 300,000 US dollars, and the 300,000 US dollars, in exchange for just a few plastic batteries.

From the high price of such batteries, Shi Lei also understands the importance of new energy batteries developed by Kong Fandong. It is a battery that can be used for civilian use. It is a product that can be mass-produced in the civilian field, not such a high-end battery. He uses black technology that feels a bit painful to use.

Including the replaceable battery, this set of equipment on the three Shi Lei can provide them with a total of more than fifteen hours of breathing time at a depth of about ten meters, which should be sufficient in any aspect.

After all, they do n’t stay in the sea all the time. With the help of the pushing device, the actual time spent in the sea is counted as four or five hours.

The reason for preparing such a long period of equipment is just in case.

Above the surface of the sea, there is a calm and calm sea. Only when the sea water is slightly undulating, it can form waves when it is pushed to the beach.

However, at a depth of about ten meters, there were three white lines. The three of Shi Lei were advancing at a very fast speed, approaching the island steadily.

According to the descriptions and records of those fishermen, Shi Lei is already quite familiar with the terrain of the island, and their goal is exactly an area that is completely unsuitable for ships to dock.

The shore is a reef salamander, and the underwater is also a variety of reefs. No matter how small the ship is, it is just a few hundred meters away from the coast, it will be stranded or even directly crashed.

But this is not a big problem for the three frogmen.

The three were cautiously limping in the sea, approaching the shore.

After careful observation, the three went ashore, and then quickly approached a small small cave under a cliff on the shore according to the map drawn by the boat people.

Under the cliff, you can actually see the face of the island.

On the distant coast, there are a lot of traces of operations left by the former fishing boats. Those piers and fish farms surrounded by the seaside have been dilapidated because of disrepair and no use, but they can still be used It can be seen that here is also a bustling crowd.

The two divers were only responsible for bringing Shi Lei to the island, and waiting for Shi Lei to return to the place of departure after completing his work on the island. To this end, Shi Lei paid them 100,000 US dollars each. They will not accompany Shi Lei into the depths of the island.

Give all the gear to the two divers and say okay, let them hide in this small cave. For a maximum of two days, Shi Lei will return here.

And if two days later, Shi Lei has not returned, they can leave on their own.

In the previous box tied to the reef, some food and fresh water were prepared, enough for the two of them to consume here for two days.

After confirmation, Shi Lei left the cave and walked towards the center of the island.

Fortunately, Shi Lei didn't go far enough to see two guards patrolling with guns above the cave.

Shi Lei hid behind a reef, observing the patrol route of the two men.

The two seemed very lazy, probably because it was impossible for anyone to break into the island. They had turned around and turned back from Shi Lei's foot two hundred or three hundred meters away.

Shi Lei is now more than 500 meters away from the cave.

Even if the guards would patrol farther after the shift, the cave should not be found, and the two divers hidden in the cave would not be found.

Not far away, Shi Lei saw a single person.

The man was wearing a white lab coat and looked like the test staff on the island, and such a person was naturally Shi Lei's best target.

Quietly approaching the guy, Shi Lei raised his palm up and down, and easily threw the man to the ground with one palm.

Then Shi Lei covered his mouth, and the man's pupils showed extreme horror, not even daring to struggle.

The man was in his thirties, and there was an ID card hanging on his chest. Shi Lei glanced and learned that this man was named Dickens, but it was a brilliant name.

Shi Lei lowered her voice and said to Dickens in English, "I don't want to kill anyone ~ www.novelhall.com ~ But if you dare to yell, I don't mind killing you."

Dickens nodded in horror, saying that he would never make any sound.

Shi Lei pulled out the dagger in his leg, reached Dickens's aorta, and slowly released his hand.

"Are you a researcher?" Shi Lei whispered.

Dickens nodded vigorously, also said in a low voice: "I am just an ordinary researcher, you must not kill me, I came here just for the high salary given here."

"What the **** is this for?"

"Study small reactors of palladium, which can provide a lot of energy ..."

Shi Lei tightened his dagger and interrupted him, saying, "I know what palladium can do. Where is your laboratory?"

Dickens shook his hand and pointed to the corner of a small white hut exposed in the jungle not far away.

"Can you get in with this?" Shi Lei pointed to the ID card on Dickens' chest.

Dickens nodded and said, "This is just a card to open the door of the laboratory. There are two guards at the door of the laboratory. If you want to get in, it's not so easy."

"You don't need to worry about this." Shi Lei snapped Dickens's neck and made him stand up, and said, "You'd better be honest, at most two days, you will be completely safe." Say, Shi Lei held Dickens back to the cave.

When the two divers saw Dickens, they were shocked. The first reaction was to pick up the weapon at hand.

But when they saw Shi Lei, they were relieved. Shi Lei said, "This person has given it to you. You should tie him up. You should eat and drink.

The two divers immediately got up and started to live. 898) More exciting novels, welcome to visit everyone's reading school
