The group of sharks was attracted by the smell of blood from the two injured sharks, and they didn't notice Hong Feifan and Ding Xiaoding at all.

Hong Feifan and Ding Xiaoding looked at each other, and they both exhaled involuntarily.

They deliberately shot sharks in order to attract other sharks.

Hong Feifan and Ding Xiaoding did not continue to watch the battle under the sea, and cautiously swam in the direction where the group of sharks swam from.

They had already learned that the staff of the castle would regularly throw entrails or injured animals in the waters near the sewers to attract the sharks.

Hong Feifan and Ding Xiaoding swam forward for about 20 meters, and gradually approached the sea, looking up, they could vaguely see the moon in the sky.

Hong Feifan and Ding Xiaoding did not surface immediately, paying attention to the movement on the water, and after a while, they felt safe on the water before slowly surfacing the surface.

The two of them did not immediately expose their entire bodies to the water, but first showed their eyes, and only after making sure that there were no people from the castle around the water before revealing their entire heads.

Hong Feifan and Ding Xiaoding glanced at each other and began to look for the sewer exit of the ancient castle.

The two searched separately, Hong Feifan to the right and Ding Xiaoding to the left.

It didn't take long for Hong Feifan to find a pile of rocks in front of him, and he faintly saw a big crack in the pile of rocks.

He was overjoyed, and thought that the big crack in the rubble was the exit from the sewers of the castle.

Hong Feifan swam towards the pile of rocks, and the closer he got to the pile of rocks, the more he felt that the water here was very different from the previous one.

A few meters further, he could see that the large crack in the rubble was the exit of the sewer.

The exit of this sewer is well hidden, and if you don't look closely, you can't tell that it's a sewer exit.

Hong Feifan turned around and gestured to Ding Xiaoding on the other side.

Ding Xiaoding immediately understood and swam towards Hong Feifan.

They found a place where they could step on their feet, and while holding on to the stones, they cautiously walked into the exit of the sewer.

It was dark inside the sewer, so Hong Feifan turned on the flashlight on his head and looked around, revealing that it was an artificially hewn cave exit.

This sewer is big, high!

It's big enough to fit five adults at once, and it's as tall as a floor.

Although the two were standing, they were not in the water below their necks.

The water here is not only sewage coming out of the sewers, but also seawater that is poured in.

Hong Feifan took off his mask and said to Yu Xiadi through the invisible walkie-talkie: "We found the exit of the sewer of the ancient castle, how are you there?"

At this time, Yu Xiadi was in the container of a medium-sized truck on the opposite shore, looking at the laptop screen in front of him.

The inside of this container has been transformed into a miniature monitoring room, and the required monitoring equipment is readily available.

The sparrows are small and have all the organs!

Yu Xiadi wore a wireless Bluetooth headset and responded to Hong Feifan: "I have already taken care of the camera at the entrance to the sewer, and you have twenty minutes." ”

"Good. Hong Feifan said.

At this time, Ding Xiaoding also took off his mask.

"You wear the glasses I gave you before you set off, just in case there are no infrared or mines in the sewers. Yu Xiadi continued.

"There can't be mines. Hong Feifan said.

"Oh?" Yu Xiadi had some questions.

"There are a lot of fish swimming around in the sewers, and if there were mines, they would have exploded a long time ago. Hong Feifan said.

"Be careful, I suggest you still wear the glasses I gave you. Yu Xiadi said.

Hong Feifan hummed, took out a pair of glasses that looked like sunglasses from the glasses case pinned to the multi-functional belt on his waist, and put them on.

Ding Xiaoding did the same.

"Wow! These glasses are nice and interesting. Ding Xiaoding couldn't help but sigh.

They wear a pair of multi-functional glasses, which can detect the presence of infrared or other alarm devices in the vicinity in addition to night vision, as well as the function of seeing through sewage.

"We're going to go inside the sewers and stay connected. After Hong Feifan put on his glasses, he said to Yu Xiadi.

"OK, stay in touch. Yu Xiadi said.

Hong Feifan turned off the flashlight and said to Ding Xiaoding: "Go!"

Ding Xiaoding nodded slightly.

So, the two of them swam into the sewers.

After less than three minutes, they found that the further they went, the shallower the water became, and the water became more and more rapid.

Their feet touched the ground and it felt like a slope.

The water was barely up to their hearts, so they simply stood and walked on, holding hands.

After going up a slope, they were blocked by a barbed wire fence.

The wire of this barbed wire fence is the size of a little finger, like a door, separating the outside from the inside.

The barbed wire mesh was not welded and had a rust-proof steel lock on it.

Although the lock is a rust-proof steel lock, it has been soaked in water all year round, and there is seawater pouring in from time to time, and the lock is still corroded and rusty.

The barbed wire fence intercepts a lot of messy garbage, emitting bursts of stench.

"It's strange, how could they get a barbed wire door here?" Ding Xiaoding frowned and said thoughtfully.

"Maybe it's to prevent someone from sneaking in from here. Hong Feifan stared at the barbed wire door in front of him and said thoughtfully.

After a slight pause, he continued, "It's also possible that it was used to prevent those sea fish from entering." ”

Ding Xiaoding nodded in agreement, and then said: "Such a barbed wire fence can't stop people at all. ”

Hong Feifan smiled and said, "For you, there is basically no door in this world that can stop people. ”

Ding Xiaoding laughed and said, "Of course!"

"Brother Hong, you get out of the way, and I'll open the lock. Ding Xiaoding continued.

Hong Feifan said "yes" and moved to the side.

Ding Xiaoding pulled out two iron bars for unlocking from a small leather case on a multi-functional belt hanging from his waist.

The lock was on the other side of the barbed wire, and it was not easy to open it.

The hole in the barbed wire is the size of a three-year-old's fist, and it is difficult for an adult's hand to reach into it.

However, these did not stump Ding Xiaoding.

Ding Xiaoding seems to be born to be a thief, his hands are softer than ordinary people's hands, and his fingers are slender than ordinary people's fingers.

Ding Xiaoding seemed to know how to shrink bones, and his hands suddenly shrank very small, and easily passed through the hole in the barbed wire.

Only a "click" was heard, and before Hong Feifan could fully see clearly, the lock was opened.

Ding Xiaoding hooked the lock to the barbed wire, then retracted his hand and opened the door of the barbed wire.

Hong Feifan smiled at Ding Xiaoding and gave a thumbs up.

Ding Xiaoding blinked a little smugly and smiled.

The two of them walked in, and the soles of their feet were no longer on the slope, but flattened. The water is shallower, not only on the thighs.

"Wait a minute. After walking a few steps, Hong Feifan suddenly stopped Ding Xiaoding.
