Lu Mingfei followed behind Lu Xiu, swimming slowly, and as the depth increased, he felt more and more laborious. But Lu Xiu looked like he was nothing, which made him roll his eyes.

Lu Xiu obviously didn't do any protective measures, not even an oxygen cylinder, but he could swim faster than the two of them put on fins.

Is it really a humanoid monster? Lu Mingfei thought helplessly. It's really more human than human, and it's infuriating.

"Pay attention to the oxygen reserves of the two of you, you can only last three hours, on the premise of your own safety." Manstein's serious voice came from the headset.

Lu Mingfei touched the black rope behind him and responded softly: "Received!" ”

Glancing at Nono, the hands of the two people involuntarily clasped together.

"Tsk, you two pay attention, this is still a task!" Inexplicably, Lu Xiu's voice actually appeared in the ears of Lu Mingfei and Nuo Nuo, and both of them were startled.

Lu Xiu was like a ghost, obviously he was still swimming in front just now, and the next second he appeared beside the two of them.

Lu Ming couldn't help but gesture, wanting to ask Lu Xiu how he could speak underwater even though he didn't have an oxygen mask.

Lu Xiu chuckled, pressed the shoulders of the two, and didn't explain anything, just lightly pointed at his feet.

A huge crack in the bottom of the river appeared in front of the three of them.

"Let's go, it's almost there." Lu Xiu gently patted the shoulders of the two of them and slowly went downstream.

The crack was pitch black, as if an abyssal maw had swallowed the three of them.

Black, in addition to black, is still black.

After entering the crack, Lu Mingfei only had this feeling left.

Fortunately, there are people around him, otherwise, Lu Mingfei would even feel that he would go completely crazy.

The kind of loneliness that the whole world has only its own left, and the depressed people are about to suffocate.

Nuo Nuo skillfully took Lu Mingfei's hand and followed Lu Xiu to a bronze wall.

The endless bronze walls are filled with a strong sense of history.

Lu Xiu gently stroked the wall, feeling the lines on it.

"It's really a miracle..."Although his own strength could be compared to that of the Dragon King, Lu Xiu was still shocked by it.

"Teacher Lu! There's a human face here! Lu Mingfei suddenly shouted.

The three of them gathered in front of a human face, Lu Xiu pursed his lips, stretched out his forbearance hand, and slowly stroked the human face.

The green treasure jade began to radiate infinite brilliance. A dull chanting sounded in the minds of the three of them, as if someone was chanting an ancient incantation in the bronze palace beneath the thousand-mile cold pool.

The mouth of the human face opened inexplicably, and gradually opened to an unbelievable size.

A burst of suction came, and the three of them were suddenly sucked in along with the river.

"Chen Motong! Lu Mingfei! What's wrong with you guys! Your band was broken just now. Manstein's voice rang out in the headset just in time.

Nuo Nuo looked at Lu Mingfei, then at Lu Xiu, and found that the three of them were all safe and sound, so he breathed a sigh of relief and reported back: "Chen Motong reported that we were sucked in by a human face, and there is no major problem at this time. ”

"It should be a living spirit, and as the Lord of Bronze and Fire, the most common method is to remove the spirit from the metal, and imprison the human soul in it for its own use. Looks like you've entered the Bronze City, is there any air around you? ”

Nono tentatively took off the oxygen mask.

"Report, there's air around."

"Be careful, it looks like Norton, the Dragon King, is right next to you!"

Lu Xiu looked left and right, but he didn't see the bronze box, and he couldn't help frowning.

After all, the seven deadly sins demanded by Brother Emperor Qi can't be neglected, and they must be found.

Could it be that Norton got him in his bedroom? You said that you sleep with a knife case on your pillow.

The three of them deliberated for a while, and prepared to walk to Norton's dormitory.

Only then did Lu Xiu know that the two of them were going into the water to bury a bomb with the effect of a large barrel explosion bomb equivalent to 10,000 stabs next to Norton, and he was caught off guard.

I have to admire the Kassel Academy's research on the dragon family, what are the five elements of ghost alchemy, and Manstein said that the head is the Tao, but in the end it was just a sentence, go down.

Lu Xiu rolled his eyes helplessly, and gently flipped his hand, and a bug emitting blue light actually appeared in his hand.

"Obviously, there are creatures in the ecological chain available, so why bother with the elements of Raushzi?"

As he spoke, he tossed the guide worm lightly, and the tiny blue dots of light flew towards it in a swaying manner.

Even if there is a maze in front of them, the three of them don't get lost at all.

"This is really..."Lu Mingfei looked at the swaying appearance of the guide insect in surprise.

"Huh? Didn't you find this bug? Lu Xiu looked at Lu Mingfei with a face full of surprise, and even Nuo Nuo had the same expression, and was suddenly quite shocked.

"Teacher Lu, thank you for discovering a brand new species!" Manstein's words were full of envy, and he didn't notice that the insects floating on the river were actually related to the dragons.

Lu Xiu was stunned for a moment, what the hell, you guys studied the dragon clan like this? I haven't even seen a guide worm, and you're still researching a dragon.

He was a little curious about how many species of dragons had been found in the Kassel Academy so far.

However, you can't ask, if you ask, you will reveal more information, although you are good friends with Ange, you can keep a hand in doing things, and it will be good for you.

The three of them sprinted all the way and followed the guide insect to a corridor.

There is water below, and on both sides stand various snake figure sculptures.

Lu Mingfei looked at the snake people on both sides and shrunk his head, he had been afraid of snakes since he was a child, and the cold, slippery snake scales really made him feel quite tired in his heart.

The snake man sculpture is lifelike, Lu Mingfei walked in the middle of the road, and there was always a feeling that the snake man sculpture would suddenly become alive, and he swarmed them up and hacked them to death.

However, after walking through the entire corridor, the snake man has maintained his original posture, and the imaginary sculpture has not come to life as scheduled, and Lu Mingfei suddenly breathed a sigh of relief.

After exiting the corridor, there is an open room, and all the water in the corridor flows into the central pool.

The guide worm has been hovering above the pool when it arrives.

Lu Xiu looked at the movements of the guide insects, then looked at the calm lake, sighed lightly, and turned to look at Lu Mingfei and the others.

"It should be down here, you two are ready, ready to run for your life at any time, it's not a joke, it's going to be desperate!" There is no lack of seriousness in the rhetoric.

Lu Mingfei and Nuo Nuo glanced at each other and nodded quietly towards Lu Xiu.

In fact, Lu Xiu completely dived to do these jobs alone, but no, Lu Ming had to grow, which was an indispensable part of his future plan.

Destroy the dragons... Then you can't let go of the slightest bloodline of the dragon clan.

Lu Xiu looked at Lu Mingfei's back and smiled helplessly.

I don't know what his expression will be at the end.

Thinking so, the three of them jumped into the pool together.
