Chapter 1229 Super Powerful Equipment

A 20-liter oxygen cylinder can provide more than one and a half hours of air supply at a depth of about ten meters, while the oxygen cylinder carried by Shi Lei and his team can provide air supply for about seven hours.

Moreover, the oxygen mask used by Shi Lei and his team is also a brand-new technological product. Even if they do not carry oxygen cylinders, they can survive for more than four hours at a depth of ten to fifteen meters in the sea water with this mask alone.

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

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

Of course, these are real luxury goods. Although this type of oxygen mask has been sold on the market, those civilian products can generally 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 for it.

The price of an ordinary oxygen mask on the market ranges from more than one thousand dollars to five thousand dollars, but the oxygen mask used by Shi Lei and his team, which can guarantee at least four hours of oxygen supply, costs nearly one hundred thousand dollars.

In addition to the diving suit, Shi Lei spent more than five hundred thousand dollars on equipment for this trip to the island.

This does not include the price of replaceable equipment. Shi Lei even prepared replacements worth three hundred thousand dollars, and these three hundred thousand dollars were only exchanged for a few plastic batteries.

From the high price of this battery, Shi Lei also understood the importance of the new energy battery developed by Kong Fandong. It is a battery that can definitely be civilianized and can be mass-produced in the civilian field, not this kind of high-end black technology that even he feels a little painful to use.

Including the replaceable battery, the equipment on Shi Lei and his three companions can provide them with more than fifteen hours of breathing time at a depth of about ten meters. No matter from which aspect, this should be enough.

After all, they didn't stay in the sea all the time. With the help of the propulsion device, the actual time they stayed in the sea, including the round trip, was only four or five hours.

The reason why they prepared the equipment for such a long time was just in case.

On the sea surface, there was calm and no waves. Only the sea water was slightly undulating, and waves could be formed when it was pushed to the seashore.

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

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

The shore was rocky and there were various reefs underwater. No matter how small the ship was, it would be stranded or even crashed hundreds of meters away from the coast.

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

The three of them crawled carefully in the sea water and approached the shore.

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

When they got under the cliff, they could actually see the appearance of the island.

On the distant coast, there were a lot of traces of fishing boats left behind. Although the docks and the fish fields surrounded by the sea had long been dilapidated due to disrepair and lack of use, it could still be seen that this place was also bustling with people in the past.

The two divers were only responsible for bringing Shi Lei to the island and bringing him back to the starting point after Shi Lei finished his work on the island. For this, Shi Lei paid each of them $100,000. They would not accompany Shi Lei into the depths of the island.

All the equipment on their bodies was handed over to the two divers, and they were told to hide in this small cave. Shi Lei would return here in two days at most.

And if Shi Lei did not come back after two days, they could leave on their own.

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

After confirming that everything was correct, Shi Lei left the cave and walked towards the center of the island.

His luck was pretty good. Not long after Shi Lei walked, he saw two guards patrolling with guns on their backs above the cave.

Shi Lei hid behind a reef and observed the patrol route of the two men.

The two seemed very lazy, probably thinking that it was impossible for anyone to break into this island. They turned around when they were two or three hundred meters away from Shi Lei.

And Shi Lei was now more than five hundred meters away from the cave.

Even if the guards patrolled farther after the shift change, they should not find the cave, nor the two divers hiding in the cave.

Not far ahead, Shi Lei saw a lone person.

The man was wearing a white coat and looked like a staff member in charge of experiments on the island. Such people were naturally Shi Lei's best target.

Shi Lei quietly approached the guy, raised his palm and slapped him to the ground easily.

Then Shi Lei covered his mouth. The man's pupils showed extreme fear, and he didn't even dare to struggle.

The man was about 30 years old, with an ID card hanging on his chest. Shi Lei took a glance and learned that the man was called Dickens, which was a very glorious name.

Shi Lei lowered his voice and said to Dickens in English: "I don't want to kill anyone, but if you dare to shout loudly, I don't mind killing you."

Dickens nodded with horror on his face, indicating that he would never make any sound.

Shi Lei pulled out the dagger from his leg, pressed it against Dickens' carotid artery, and slowly released his hand.

"Are you a R&D staff?" Shi Lei asked in a low voice.

Dickens nodded vigorously and said in a low voice: "I'm just an ordinary researcher. Don't kill me. I came here just for the high salary here."

"What is this place used for?"

"A small reactor for studying palladium, which can provide a lot of energy..."

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

Dickens trembled and pointed to a small white hut in the dense forest not far away.

"Can I 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 may not be that easy."

"You don't need to worry about this." Shi Lei suddenly lifted Dickens' neck and made him stand up, and said: "You'd better be honest. You will be completely safe in two days at most." After that, Shi Lei took Dickens back to the cave.

When the two divers saw Dickens, they were shocked and their first reaction was to pick up the weapons at hand.

But when they saw Shi Lei, they breathed a sigh of relief. Shi Lei said, "I'll leave this man to you. Tie him up and give him food and water."

The two divers immediately got up and got busy.
