With a "bang", Wang Lu's back smashed directly on the thick ground, and Wang Lu opened his eyes and saw the blue sky outside the cave entrance.

Then, Wang Lu heard the sound of 'bang-la-la' water flowing in his ears. Wang Lu stood up from the ground, and the black cloak was leaning against the stone wall, looking at the side with an indifferent expression. Next to him, stood a man in a blue military uniform with a glass protective mask.

Wang Lu patted the dust on his body, originally wanting to express a few words of resentment that had fallen, but after looking at the black cloak's demeanor, he couldn't say anything. Then, Wang Lu set his eyes on the other person, and he was also looking at Wang Lu at this time.

Wang Lu immediately understood in his heart who was wearing a military uniform in front of him, and his identity had been clearly mentioned in the document given by Bingshan Niu. As soon as Wang Lu stood up, he stepped forward and said to Wang Lu: "Hello, I am the captain of the Seventh Underwater Brigade, Ji Aosen. Thank you for coming and helping us. ”

"Hello, my name is Xingyun." Wang Lu immediately stretched out his hand, the hands of the two shook gently, and Ji Aosen took his hand back, "I'm glad to see you, as for what you need to do, you just need to go to the front." Where there's an observation point, we've always had an observer there, and he'll tell you how to do it. ”

Wang Lu glanced sideways slightly, and Wang Lu found that Ji Aosen's skin was a little dark. The various technologies for skin care in the Federation are still very developed, and the appearance of dark skin must indicate that this person is often active under the scorching sun.

Wang Lu squinted slightly, looking at the attributes of Ji Aosen...... I was sure that he wasn't a regular visitor here.

Giosen: (Because he wears equipment that hides his identity, he is hidden in the low-level MONOCULUS detection) Skill: Hidden.

It was obvious that Giosen had noticed that Wang Lu was spying on him with his little demon eye, so he thought that Wang Lu showed a harmless smile. Wang Lu was a little embarrassed, apologized to Giosen, and then turned to leave.

"Mr. A, I rarely see you?" After watching Wang Lu walk away, Ji Aosen set his eyes on Mr. A, but his tone was not as kind to Wang Lu.

"Hmm. Got a commission that I couldn't refuse. The black cloak raised his head and looked at Giosen, a smile slightly appeared on the corner of his mouth, "Do you know whose Dao it is?" ”

Ji Aosen didn't show any curiosity, but pointed in the direction where Wang Lu left: "Who is he?" ”

"Guardians of the client who can't refuse." Black Cloak replied.

Giosen was stunned for a moment after hearing this, and wondered: "So weak? Who can't even you refuse? ”

"I thought you wouldn't ask." The black cloak glanced up at Giosen, and then pulled out a fishing rod from a spatial device, "I'm going to stay here for a while, I've heard that the fish in the underground river are particularly delicious, and I don't know if it's real or fake." ”

Ji Ossen looked at the black cloak coldly and said, "You'd better not have any ghost ideas, otherwise I will send you to see the master immediately." ”

"Where is the Juggernaut, have you seen it?" Black Cloak took the fishing rod and walked to the river, and when he was about to arrive, Black Cloak suddenly turned around and smiled at Giosen: "Actually, it doesn't hurt to tell you, the person who entrusted me is actually 'Miss Bing'." ”

Giosen's face changed suddenly.

When the black cloak provoked Ji Aosen with words, Wang Lu had already seen a small house. When Wang Lu approached, he saw the three words 'Observatory' of the Federation above.

Wang Lu walked to the door and knocked, the red light on the side of the door flashed, and then the door opened automatically.

A young man dressed very similarly to Ji Aosen stood up, and he stretched out his hand towards Wang Lu with a sunny face: "Hello, my name is Zhang Mingxiao." ”

"Hello." Wang Lu shook his hand gently, and then looked at his attributes.

Zhang Mingxiao: Health 23/23, Energy 15/15, Attack 12~12, Defense 15. Skill: Hidden. (Because he wears equipment to hide his identity, he is hidden in low-level MONOCULUS detection)

Unlike Giosen, Zhang Mingxiao's attributes were still partially exposed to Wang Lu's detection, and Wang Lu naturally understood that this was because the two people's hidden attributes were not at the same level.

However, at this time, Zhang Mingxiao frowned, he looked at Wang Lu and said, "Has anyone ever told you that it is rude to use the magic eye to detect others, especially in front of others." ”

"Huh? I'm sorry, I'm sorry. Wang Lu's eyebrows furrowed, neither the black cloak nor the Giosen mentioned this. Especially Giosen smiled heartily at him before.

"It seems that you really don't know what to do." After seeing Wang Lu's expression, Zhang Mingxiao was relieved, and he smiled and said, "It's okay if you don't know what Lu Dao says, but you have to pay attention to this in the future." ”

After speaking, Zhang Mingxiao walked to the back, then took out the coffee pot and poured a cup of coffee and handed it to Wang Lu, and said, "Thank you very much for coming here, we really need your help." ”

After handing the coffee to Wang Lu, Zhang Mingxiao sat on the chair, and Wang Lu also sat on another chair. Zhang Mingxiao continued to speak: "You should know what kind of trouble we are encountering, all the scientific and technological personnel of our brigade have accidentally fallen into the water, although their lives can be guaranteed in biological dormancy, but we urgently need to rescue them." ”

After speaking, Zhang Mingxiao looked at Wang Lu with eager eyes.

Regarding the underground river, Wang Lu already has some knowledge. In the documents given by the iceberg girl, these have been explained very clearly.

However, in Aoki City's introduction, the underground river is a different story. It's also a dungeon, Wang Lu has only heard of it but hasn't been there, and some players say it's troublesome to come here...... But as far as Wang Lu saw and heard before......

It's not just a hassle. At least he couldn't come to this place without a black cloak.

However, Wang Lu soon found that the copy in front of him and the copy in the mouth of the players in Aoki City were just the same, and if Wang Lu hadn't made a mistake, what the players said might just be one of the entrances to the copy.

And this observatory is very telling if it doesn't see the player.

As for the origin of the underground river dungeon, it is much more interesting, according to the official theory, because the river below it has a lot of valuable and research things, so it attracts many people to enter in wetsuits. The Federation's wetsuit has a deep hibernation function, which can be activated if you get lost underwater.

However, this underground river has a strange and extremely powerful electromagnetic interference, and at the same time, it is said that there was once a famous person who was bought at a price of 10 million because he salvaged an inexplicable thing, which led to the emergence of a large number of people who were dormant because they were lost in the river. Officially, they are called the ones to be saved.

It's just that in Zhang Mingxiao's mouth, the identity of the person who dived under the river changed.

"I'll go down at once." Wang Lu nodded and replied.

"That's so grateful." Zhang Mingxiao had an unpretentious smile on his face, he pointed to the seat in front of him, and said to Wang Lu: "If you are tired, you can come here to rest." ”

At this time, a message suddenly appeared on Wang Lu's electronic navigator. Wang Lu lightly pressed on the little demon eye, and the information appeared on Wang Lu's retina.

Friendship with a member of the 4th Naval Brigade is developed, and friendship with the Brigade is increased by 1.

Now has (77/100) friendship.

Wang Lu glanced at the favorability of this 77 and probably understood its origin. Fifty-one of them are there when they enter the game, and then twenty of them are the result of the Medal of Honor. There are also 5 missions completed for Aoki City. The last 1 is the result of the relationship with Zhang Mingxiao just now.

But Wang Lu suddenly found that the relationship developed to an intimate word......

Wang Lu immediately gave instructions to the little demon eye and called up the information about the intimacy. The little demon eye also quickly provided information, and then Wang Lu was dumbfounded.

The minimum affinity requirement is...... 301。

Wang Lu made a quick calculation in his heart, and then decisively found that if he wanted to have a good relationship with the Fourth Naval Brigade, he needed to establish friendly relations with a total of two hundred and thirty-four members of the Fourth Naval Brigade. But there were only two people in the Fourth Naval Brigade he saw at this time, and the one on the outside seemed to be very awesome, and the one on the inside was useless.

"......" Iceberg girl gave him this task, is it really not to embarrass him sincerely?

"What's wrong?" After Zhang Mingxiao noticed that Wang Lu's expression was a little unnatural, he immediately asked with concern. Wang Lu could only cope and say, 'It's okay'. Wang Lu retreated from the room, and his heart quickly thought about it.

This task will not be impossible, and Iceberg and Black Cloak will definitely not foolishly tease him, especially when he is about to fight with Black Cloak.

Wang Lu turned his head to look underwater, and he could believe that the key to what the iceberg girl had told him should be in the flowing underground river.

The underground river is naturally a dark place, and the only light is the small flickering lamp placed next to the observation post, but I don't know what the road is for, and it is a yellow dim light lamp. The sparkling waves of the underground river showed a few bewitching colors in the light.

Wang Lu changed the equipment on his body, and then took out his diving suit. The wind in the underground river was very cold, and it was quite cold on his body, Wang Lu immediately put on a diving suit, and then Wang Lu heard the prompt of the system.

"No. BN****3490 wetsuit intelligent service system is at your service."

“……！” Wang Lu was stunned for a moment.

"The presence of advanced telescopes and strategic eyes is detected, and whether to choose to replace the original underwater viewing lenses."

"If the ambient temperature is too low, whether to turn on the thermostatic system."

"Electronic interference detected, whether the electromagnetic shielding is turned on."

"Space settings detected, whether to select space settings external."

"...... Detected"

Wang Lu suddenly discovered that it was indeed a very good behavior for him to go to the cold beach in the middle of the night before......
