Su Wanwan stopped, walked to the only vertical water pipe on his side, set the bone spirit to wait in place, and climbed up along the slender pipe, and climbed to the top of the 3-meter-high water pipe without much effort.

The water pipes above the sewers do not always lead to the mutant rat king from the doorway, but there is a large point above each section of the sewer, although it can barely stand people, but the pipes are horizontal and not connected.

Su Wanwan looked at the empty walkway below, looked up at another pipe 2 meters away in front of her, and took out the hemp rope she had just bought in her backpack.

Skillfully tie a piece of copper to one end of the hemp rope and throw it at the opposite pipe.

"Ok! Su Wanwan pulled the hemp rope that had been thrown to the opposite side, and then bolted it tightly to the pipe on her side.

Carefully climb along the tied hemp rope to the opposite pipe.

From the doorway to the inside of the sewer, there are a total of 10 such pipes.

The more she went to the back, the more skilled Su Wanwan's technique became.

"Oh mom, I'm finally on the side of the mutant rat king, fortunately I don't have a fear of heights, otherwise I really wouldn't be able to do this job!"

Su Wanwan patted her chest with palpitations, sat down at the top of the water pipe, took out a few bottles full of gasoline from her backpack, and spilled them on a huge circular ground below.

"Didi ......"

The sound of gasoline dripping was exceptionally clear in the empty sewer.

It wasn't until all the gasoline bottles in his hand were poured that the ground was just sprinkled with gasoline.

It's a circular ground below, but there are no mutant rats or mutant rat kings.

Su Wanwan was not in a hurry at all, the mutant rats were hiding under the sewers, judging the distance by the sound of the player's walking, and he didn't walk in at the beginning, and the mutant rats didn't notice it at all, and they had already entered the place of the mutant rat king.

In the territory of the mutant rat king, there is usually no mutant rat who dares to approach, and when more than half of the mutant rats are killed, the mutant rat king will appear.

Su Wanwan finished pouring the gasoline, put the empty bottle back in the backpack, and took out the fire fold and fuse, and then brought up the setting page of the bone spirit, and set the place to wait in place to follow mode.

I saw the bone spirit still standing at the door, staggering towards the inside of the sewer.

The bones stepped on the waterlogged ground, and the sound of their footsteps was distinct in the empty sewers.

"Click, click, click......"

Su Wanwan saw the bone spirit walking towards him leisurely, and when he was about to walk out of the range of the third wave of mutant rats, he used a fire fold to ignite the fuse.

The ignited fuse makes a "bang" sound.

At this time, the bone spirit also walked to the edge of the circular clearing, and suddenly a large number of obese mutant rats rushed out from behind him, rushing towards the bone spirit.

Su Wanwan hurriedly added blood to the bone spirit, but there were too many mutant rats that rushed out, and the bone spirit fell apart without holding on for two seconds.

"Good work, your task is accomplished!" Su Wanwan silently sighed for the scattered bone spirit.

Although the bone spirit fell apart, because of Su Wanwan's last blood return skill, the hatred of the mutant rat shifted to Su Wanwan, and the mutant rat below did not leave, but gathered more and more, densely.

"Squeak...... Roar...... Creak...... Click......"

The mutant rat below couldn't jump a distance of 3 meters at all, and there was no pipe connecting to the ground around this circular clearing to climb, so the mutant rat could only look at Su Wanwan above with its teeth and claws, and let out a low roar from its mouth.

After a while, Su Wanwan saw that the three waves of mutant rats were almost all there, so he threw the fuse in his hand.

As soon as the fuse touched the mutant rat stained with gasoline, it burst into flames.

“―514”

"Critical Hit-800"

“―632”

In the blink of an eye, the fire spread, and Su Wanwan saw a large area of damage floating below.

The burned mutant rats jumped up and down in pain, trying to get back to the bottom of the sewer, but unfortunately for the mutant rats with only 3000 blood points, the fire attack damage was too high, and most of the mutant rats didn't run a few steps before they burned to death.

And a few mutant rats that were lucky enough to escape back to the bottom of the sewer were also injured by fire poison because of the extensive burns on their bodies, and after continuing to lose blood, they died after a while.

In less than 30 seconds, most of the mutant rats were killed and injured.

When Su Wanwan saw that the number of mutant rats in the taskbar had died to 150, a huge roar sounded below.

The mutant rat king has finally appeared.

I saw that the mutant rat king was half an adult's size, and his body was even more fat, but his movements were very agile.

As soon as the mutant rat king appeared, the mutant rats around him consciously leaned back, but unfortunately the ground was full of gasoline and charred mutant rats.

The mutant rat king didn't take a few steps, and his feet were stained with gasoline, and he began to burn as soon as he was touched by those mutant rats that were still burning.

"Ahh......h

I saw that the fur on the feet of the mutant rat king was burned black, revealing the pink skin inside, and the blood volume on the top of the head began to slowly decrease, although the decrease was not very much per second, but the mutant rat king screamed in pain.

However, the mutant rat king was obviously much smarter than those mutant rats, and instead of sitting still, he screamed in pain while running towards the drainage channel in the outer circle of the clearing, apparently planning to use the water in the drainage channel to extinguish the fire.

The mutant rat king stepped into a drain pipe with both feet, and sure enough, the fire on his feet was extinguished after a while, emitting a puff of white smoke, followed by a stench of burning.

The soles of the mutant rat king's feet were cool, and he felt a lot more comfortable, seeing that the fur on his feet was burned to the ground, and the exposed skin was scorched, he turned his head and glared angrily at Su Wanwan above.

Su Wanwan didn't seem to notice it at all, but changed her comfortable posture and continued to observe the mutant rats that were burning around right below.

The mutant rat king roared angrily, and rushed in the direction of Su Wanwan, and the heavy footsteps shook even the sewers.

Unexpectedly, an incredible scene happened, the mutant rat king just ran a few steps, and at this time, a mutant rat with residual blood just ran to the edge and touched the tail of the mutant rat king, only to see that the mutant rat king began to smoke and burn from the tail, and along the dark hair on his body, the fire spread to the whole body in an instant.

It turned out that although the mutant rat king had just extinguished the fire on his feet, the gasoline attached to it was insoluble in water, and the gasoline floated on the water, and then as soon as the mutant rat king walked, the gasoline immediately got on its body and tail.

The Mutant Rat King is now covered in burning fires, and the water in the drain pipe is simply not enough to extinguish these fires.

Amid the miserable cries of the mutant rat king, his HP continued to decrease.

In just a minute or so, the mutant rat below Su Wanwan and the mutant rat king died, leaving behind a place of copper coins and equipment.

"Mission: Destroy the Mutant Rat, Destroy the Mutant Rat King has been completed. The completion rate is 200%, please go to the door of the dungeon and talk to the guards to deliver the task. ”

"Sewer dungeon simple mode, clearance time 20 minutes and 12 seconds. ”

"Congratulations to the team of Xiaoqiao Flowing Water for becoming the first place on the Sewer Dungeon Simple Mode leaderboard, do players need to hide their names?"

Of course, she chose to hide, Su Wanwan didn't want to be the target of public criticism.
