"From what I've heard, Nadep hasn't handed over our national treasure yet. Hong Feifan said.

Ding Xiaoding said "um" clearly.

"In this way, we continued to observe and understand the inside and outside of the castle, and try to gather as much information as possible. Hong Feifan continued.

"Roger!" Yu Xiadi said.

"Okay!" Ding Xiaoding nodded.

"We don't have much time, though. My plan is to act tomorrow night. Hong Feifan said with a serious face, "Whether we can get more information or not, we will act tomorrow night." ”

"Why tomorrow night?" asked Ding Xiaoding.

"I've been told that Nadepp will be leaving home tomorrow to attend a conference on European business in Great Britain and will probably not be back until two days later. Hong Feifan said.

"Understood!" Yu Xiadi and Ding Xiaoding nodded in unison.

"Xiao Ding," Hong Feifan's gaze turned to Ding Xiao Ding, "You try to find as much information as possible about the sewer in the castle manor, the more detailed the better." If we can't sneak into the castle by land, we'll have to dive into the castle through that sewer. ”

"Okay, I'll do my best to gather information about that sewer. Ding Xiaoding said.

Hong Feifan said "um", then moved his gaze to Yu Xiadi, and said, "Adi, are there cameras or other monitoring equipment installed near the exit of the sewer in the castle manor?"

"There were no cameras near the exit of the sewer, but there were two cameras near the entrance to the sewer. Yu Xiadi said.

Hong Feifan nodded thoughtfully.

"The sewer camera is not a problem, it is easy to get it, but I don't know if there are other alarm devices or other security devices installed in the sewer. Yu Xiadi said.

"I'll leave this matter to you to investigate. Hong Feifan said.

"Roger!" Yu Xiadi nodded.

......

At midnight the next day, Hong Feifan and Ding Xiaoding drove a speedboat to the middle of the bay at the back of the castle.

The two changed into black wetsuits and spent time with each other.

"Let's go!"

With Hong Feifan's voice, the two jumped into the sea one after the other.

As soon as the two of them sank into the sea, they did not stop, and immediately dived to a deeper place.

If it weren't for the harpoon guns in their left hands and the oxygen cylinders on their backs, they would have swam faster.

Although they were not as fast as they could swim without any equipment, they were not very slow, and they had not been able to dive under a coral in less than three minutes.

They paused there for a moment, adjusting slightly.

It's already winter, and it's already cold. However, because they wore wetsuits made of rubber, they felt that the temperature in the sea was not as cold as on land.

It's not a very deep place, and under the effect of the moonlight, you can barely see the surrounding environment clearly.

Hong Feifan made a gesture to Ding Xiaoding, and Ding Xiaoding nodded knowingly. Then, the two continued to dive.

As you dive deeper and deeper, the light gets weaker and weaker.

Hong Feifan ventured to turn on the small flashlight on his hat, and the water around him immediately moved. Many small underwater animals swam towards them, and many small underwater animals were frightened by the sudden light and fled in all directions.

The underwater light is dark and unclear, and the hard coral reef forests are full of dead ends. If you're not careful, you'll run into those coral reefs.

They dived down for another two minutes or so and saw the bottom of the sea.

Their feet touched the ground, their hands on the reef, and then the coral, half-walking, half-swimming, in the direction they were going.

Strangely, there were no other fish here, big or small.

Hong Feifan communicated with Ding Xiaoding a few times in sign language, reminding Ding Xiaoding that they might have entered the piranha area.

Before they came, they had already learned that the beach near the castle was stocked with a lot of man-eating fish, especially for those who wanted to sneak in from the water.

In addition to man-eating fish, magnetic mines are also placed inside the sewers, and if you are not careful, you will be killed.

Just as Hong Feifan was raising his vigilance, he vaguely saw two black shadows swimming towards them.

The two black shadows that Hong Feifan noticed, Ding Xiaoding also noticed.

Based on the experience of the two of them, they immediately realized that those two black shadows were not a good thing.

Hong Feifan gestured to Ding Xiaoding, and Ding Xiaoding immediately pointed the harpoon gun in his hand at the black shadow in front of him.

Soon, they saw a shark that was less than six meters away from them. Immediately afterward, they saw another shark.

It was a shark the size of their body, following the light of the flashlight on his hat.

Hong Feifan immediately realized that he immediately turned off the flashlight.

At the same time, he made a gesture to Ding Xiaoding, signaling him not to use a harpoon gun against sharks.

Ding Xiaoding was about to shoot the harpoon, and when he saw Hong Feifan's prompt, he swam to the side.

Hong Feifan followed by bending over, and with his left hand, pressed a palm-sized electronic device on the condyle of his foot.

This device is a shark repellent, which is capable of emitting high-intensity electrical pulses that cause muscle spasms in approaching sharks and in this way drive sharks away, with an effective distance of more than eight meters.

Sure enough, the two sharks suddenly dispersed and swam somewhere else.

Looking at the shark swimming away, Hong Feifan's eyes rolled, as if he thought of something, and he made two gestures to Ding Xiaoding.

Ding Xiaoding immediately understood, raised the harpoon gun in his hand, and aimed it at a shark swimming behind.

At the same time, Hong Feifan also raised the harpoon gun in his hand and aimed it at another shark.

Suddenly, Hong Feifan and Ding Xiaoding pulled the trigger one after another.

"Whoosh" twice, and the harpoon shot out.

The two sharks were then shot by the harpoons and suddenly tumbled and leaped, stirring the water like a whirlpool.

The blood from the two sharks shot by the harpoon then dispersed in the water.

After Hong Feifan made a gesture to Ding Xiaoding, the two sped up and swam away.

Suddenly, the sea in front of him was in a commotion, and immediately after, a large group of small fish and shrimp rushed towards this side, as if they were hiding from something.

Hong Feifan seemed calm, as if he already knew what was behind the group of small fish and shrimp.

He gestured to Ding Xiaoding again and swam to the side.

Ding Xiaoding understood what Hong Feifan meant, and also swam to the side.

Soon, they saw a large group of large and small sharks appear behind the group of small fish and shrimp.

Hong Feifan and Ding Xiaoding frowned, and gave way to these sharks.

The large group of sharks soon appeared around the two sharks that had been spear-shot, and then the group of piranhas went crazy in the water, tearing at the bodies of the two injured sharks like a pack of wolves that had not eaten in days.

They didn't pay any attention to the two injured sharks' counterattacks, and just tried to bite desperately.
