Boss Mu was in high spirits, and with a wave of his hand, he stepped into the range of the ruins.

Judging from the scope and extent of the collusion of the dark aura above the heads of these monsters in front of them, the chain hatred of these elite monsters is no longer as large as the previous two groups, about seven or eight together.

They will be 'carefree' and can enjoy the experience.

This is the opportunity for rapid improvement in strength.

But after fighting for several hours, most of the black devil goblins in this town were cleaned up, and Linglong was promoted to level fifty-seven, but they still didn't find the downward entrance in Boss Mu's mouth.

The plot of this step is for them to 'clean up the ruins', which is a typical monster farming, and the team cleans up the streets and alleys to try not to let one go.

An elite can represent a lot of experience, and it is absolutely shameful to waste it.

After another half a day, the monsters on the streets seemed to have been completely cleared by them, and the first floor of the entire ruins became empty, but they didn't find the entrance to the second floor, and they didn't hear any system prompts.

Mu Qian: "Look around, clean up monsters when you see them, and call for support when you encounter a boss or any other danger." Be careful. ”

The six of them were on the bridge of the central river channel, divided into four groups and headed in all directions.

It is a stone arch bridge that spans the river and stands right in the middle of this rectangular town. When the ancient goblins planned this town, they just set the apex of the arch bridge as the center of the rectangle.

Viewed from the air, the arched bridge is the only link that connects the streets to the east and west.

I don't know how many years ago, when the ancient goblins lived here, the bridge should have been a bustling scene of traffic, so it was built to a width of 15 meters, and it was still strong at this time.

Wanyue, Linglong, Vanilla and Hammer World each have one group, while Mu Qian and Hong Lingjin act alone, so the four groups can be regarded as balanced in strength.

"What should the entrance to the next floor look like?" Linglong asked.

"Since it's downward, it's similar to a pit like a mine," Hong Lingjin analyzed, adding, "It could also be a teleportation array." ”

The elf girl also actively made suggestions: "It's all clear here, these rooms are so simple in structure, the entrance shouldn't be hidden in the building, there must be some mechanism that we have overlooked." ”

Hammer the world hurriedly said: "This statement is very reasonable. ”

A few people began to bury their heads in searching, and by the way, they checked their previous cleanup work, but they didn't find any missing targets.

Mu Qian's gaze was like a sophisticated scanner, and he didn't miss any details in his fast-moving state, and he didn't find anything unusual in his search of the streets.

They also occasionally bump into each other, as they don't have access to the minimap and system map, and they can't know where their teammates are in real time. But everyone has the mentality that they would rather check a few more times than miss anything, and continue to run around here.

"Alas, this is the rhythm of digging three feet into the ground." Wanyue looked up and sighed, her eyes showing signs of being empty.

The delicate girl who knew her well smiled lightly, and her fingertips pointed a little towards her neck, and a few ice cubes the size of fingernails slid into Xiao Wanyue's delicate skin.

Wanyue's chivalry was shocked, and she rushed towards her sister with her teeth and claws.

The ice, as she ran, slid out from under her armor.

Unexpectedly, there was no hindrance......

There's no one left.

After an hour of running, the six of them ran through the streets and alleys again.

Wanyue, who had the worst patience, flattened her mouth and couldn't help complaining: "Could this system god be that you are too strong, Master, and just find a reason to trap you here?" ”

Boss Mu was silent.

But come to think of it, this story is different from the others, and the player will be resurrected in a random area here after death...... Wait, random resurrection?

Thinking of this, a bright light flashed behind the head of the Hammer World, and he excitedly shouted on the team channel: "I thought of it!" ”

"What comes to mind?" Several people hurriedly asked.

"We really can't, we can ...... Suicide, since it's a random place to resurrect, so come a few more times, how can you run into the bottom! Right! ”

Several people could only hold their foreheads with one hand.

Hong Lingjin: "Expose your IQ, brother!" ”

Vanilla Milkshake: "You win." ”

Wanyue said weakly: "Or, Brother Hammer, you try it first?" ”

"This," the hammer of the world, which was a little regretful as soon as the words came out, replied wittily: "I just enliven the atmosphere, enliven the atmosphere...... Ah! ”

Mu Qian couldn't help asking, "What's wrong?" ”

"It's okay, I've fallen into the pit."

Hammer World silently sent a crying emoji, and then scolded hatefully: "Next to these streets, why are you building so many pits!" ”

Linglong smiled: "It's not a pit, it's a ditch built on both sides of the street, so that rainwater can collect on the side of the river." ”

Ditch?

Hong Lingjin was stunned and asked, "Will it rain here?" It's underground. ”

"yes." Xiaoice blinked and turned his head to look at the regular ditch on the side of the street that was fifty centimeters wide and one meter deep; At the door of each of the ancient goblins' dwellings on the street, there was a stone slab on top of these ditches.

"So what are these ditches for? Sewer? Linglong leaned over and looked at it carefully, and wondered: "It's not good to be directly exposed to the side of the street, right?" ”

Wan Yue couldn't help but smile: "Sister, why does your analysis still have a taste!" ”

"If this is really an ancient goblin slum, then these ditches can be filled with water, and a lot of food can be floated, right?" Vanilla milkshake analyzes, "Just like a lot of Japanese food. ”

Hong Lingjin jumped into the ditch on the side of the street and stepped on it, and jumped up again, "But knowing this, it doesn't seem to have any effect." ”

ditches, water, water injections...... The water flows, when it rushes to this side, and the twists and turns encountered on the road......

Dams, Watchmen, Ruins of Destruction, Ancient Goblin Ruins definitely exist in multi-layered underground structures......

Boss Mu is brainstorming.

"Back to the bridge!" He suddenly whispered.

When several people heard this, although they didn't know why, they also began to run in the direction of the Central Bridge.

Mu Qian rushed to the bank of the river, looking at the water that was half a meter above him, and the big sword was thrust into the water.

A faint ripple of water floated by, but as the ripples gradually calmed down, there was no trace of it anymore.

He drew his big sword and ran towards the stone bridge, and his heroic jump landed directly in the middle of the stone bridge. Mu Qian took out a few slices of hard bread in his backpack and threw them out.

The bread slice floated on the surface of the water, almost at a slow speed invisible to the naked eye, towards the lower reaches of the river.

"What's going on?" Wan Yue leaned her head out from beside him, and several people arrived at about the same time.

"The speed of the water is very slow," Hong Lingjin said as he looked down the river, still unable to see the edge, "and even said that it would not flow at any standstill." ”

"Not bad." Mu Qian nodded and said, "The water flow we saw on the side of the dam was very turbulent because of the pressure of the water potential, do you still remember?" ”

The two men and three women who had all gathered beside him nodded at the same time.

Mu Qian said: "From the dam to this town, the speed of the water gradually slowed down due to repeated bends and the obstruction of the embankment, but the width of the river did not increase. Where did all that water go? ”

A slight smile finally appeared on his lips, and he continued, "Do you remember what the previous watcher said? What is he going to do when the forces of evil touch the last dignity of the goblins? ”

Linglong blinked: "He's going to destroy the entire ruins by destroying the dam......"

"That's right! If there was no downward passage in the river, how could he destroy this ruin? The core area of the goblins must be deep underground! ”

A slight smile appeared on the corner of Boss Mu's mouth, and he pointed to the lower reaches of the river: "Although we can't see it here, there will definitely be a dam ahead to block the flow of water." Go to the entrance of the town to test the water flow, the flow rate should be normal, but go to the town exit to measure, the flow rate should be so weak that it is not counted. ”

Hong Lingjin looked down at the calm surface of the river, their shadows reflected in the smooth mirror-like surface of the river. The two pages of bread wet by the river also began to expand and soften.

Xiaohong muttered, "...... below"

The vanilla milkshake was the first to react, and it dawned on her: "That is, the water is flowing underground?" But then, there should be a whirlpool here. ”

"If it's not a stream, but it seeps through small holes?" Hong Lingjin said.

Mu Qian smiled: "What the hell is, go down and see." Wait here, and I'll go down. ”

"Boss, I'll go." Hong Ling in and out of the channel.

"It's fine." Mu Qian nodded, Hong Lingjin slapped the railing of the stone bridge, and the whole person jumped out.

There was a bang, and there was a splash, but Hong Lingjin, who just wanted to dive, said on the team channel: "This side is only two meters deep......"

The river water poured into his throat when he opened his mouth, and Hong Lingjin's voice was quickly broken. But in less than half a minute, he peeked out of the river and wiped the clear water from his face.

"What's wrong with the bottom of the river?"

"It's flat down there, there's no sediment, and there's a little whirlpool at the bottom of the river...... However, the holes leading to the bottom are only the size of thumbs, and it is impossible for us to pass through here. ”

"Let's see if there's anything else, a button or something." Mu Qian said.

Hong Lingjin nodded and dived again.

Standing on the arch bridge, you can clearly see his figure swimming under the water.

Holding his breath for a minute, Hong Lingjin came out again and reported: "A palm-sized semi-circular stone, I didn't pull it, but I heard the sound of the bracket, and I should be able to press it." ”

Regarding the caution of the Shield Heavenly King, Boss Mu was also a little speechless, "Press it down and try it, be careful." ”

"Hmm." Hong Lingjin nodded in response and dived under the river for the third time.

But this time, it was only a few seconds, and Hong Lingjin rushed up, "There is movement!" ”

Click! Bell, bell!

Wanyue rolled her eyes: "We are not deaf!" Heard it! ”

Like the sound of some kind of huge metal gear turning, Xiao Wanyue suddenly pointed to the area of the river where Hong Lingjin was, but saw a shadow rushing up from the bottom of the river.

"Stinky boy, get out of the way!"

Hong Lingjin was caught off guard, and the speed at which the shadow rose was also rapid, directly pushing the floating shield battle straight up, rushing out of the river with the sound of rushing water, and standing two meters away from the stone bridge.

But it was a huge black pillar that broke out of the river at a height of two meters.

From a depth of two meters, the pillar is four meters high and three meters long and wide. It's dark throughout, but you can't find any gaps up and down.

Hong Lingjin was sitting at the top of the stone pillar, grinning at them, and comparing a scissor hand to represent victory.

Xiao Wanyue rolled her eyes: "Childish! ”

Linglong was curious: "Is this the elevator of the ancient goblin?" ”

Hum -

The stone pillar trembled, facing this side of the stone bridge, and a crack opened at the top.

This stone wall slowly fell towards the stone bridge, and judging by the length and the angle of the dumping, it should be just enough to be able to build on the stone bridge.

The humming sound, like the engine controlling the stone wall, suddenly gave the picture a sense of technology.

But several people, including Hong Lingjin, who was sitting on top of the stone pillar, all looked serious at this time, and Hong Lingjin grabbed the shield and stood up.

Mu Qian raised his big sword, and naturally protected Linglong and Vanilla Milkshake behind him, staring at the slowly opening in front of him, and several other people were also brewing their own attacks.

There was no other, because among the open stone pillars, there stood a low and majestic black shadow wrapped in the aura of darkness.

That stream of black gas also swept out......

It asked in a deep voice:

"What are you looking for? Death? It's been waiting for a few people for more than a few hours. ”
