Nothing happened overnight, which can be considered good news, compared to being in the limelight and adventuring in the wilderness, peace is a blessing.

"How is it arranged today?" Wei Yi asked as he got up early in the morning and looked at the turmoil.

"Dong Feng's brother and sister and Wu Wei are in a group, go to find the entrance to the sewer, and survey the route, and bring all the instruments!" Feng Bo looked at Wu Wei and the others, waiting for their answers.

"I don't have a problem, although I have a small tail, I can handle it. Wu Wei said indifferently.

"You don't have an opinion, I still have it?" Xiao Ting heard Wu Wei's ridicule, and immediately looked like a kitten whose tail had been stepped on, opening her teeth and dancing her claws as if she wanted to scratch someone.

"Xiao Ting!" Dong Feng immediately stopped and glared at Xiao Ting.

Hearing her brother's scolding, Xiaoting shrank her head, lowered her head and stopped talking, and then turned her head to see Wu Wei's appearance as if she was smiling, and snorted at Wu Wei again, very unhappy.

"Okay, then it's decided, as for me and Weiyi, we are responsible for guarding the perimeter, cleaning up the small troubles by the way, if you encounter something that you can't afford to provoke, you are ready to retreat at any time, and we will try to gain time. After speaking, he looked at Wei Yi and waited for his opinion.

"I have no opinion, just do as you say!" Wei Yi said noncommittally.

"Then it's decided, Xiaoting controls the instrument, Dong Feng and Wu Wei protects, the two of us are on guard on the periphery, if there is force majeure, I will give you a signal, as for the hidden risks, it depends on the two of you, if there is no problem, then go." The storm finally summed it up.

Subsequently, Xiaoting took out a circular compass-shaped instrument, and after turning on the switch, the screen showed a low structure, and it can be seen that some lines of different thicknesses appeared on the screen, and after entering a few parameters, only a straight line remained.

"It should be going southeast. Xiaoting looked at the compass, and then said to the storm.

Fengbo and Wei Yi glanced at each other, and then ran towards the southeast.

The two of them swept all the way, and if they encountered a small group of demon beasts that could be solved, they would destroy them all, and if they encountered something that they couldn't deal with, they would lead them away, as long as they waited until Xiaoting tested it, they didn't have to worry about it anymore.

The five of them worked hard for a whole week before they finally measured a small area within a radius of five kilometers.

Feng Bo looked at the three-dimensional structure of the underground pipeline in front of him and fell into deep thought.

"How is it, can you start?" Wu Wei asked listlessly, in the past few days, he has been tossed by Xiao Ting enough, when measuring, he is always startled, and then he commanded Wu Wei to either go to the small pit in front to check, or go to the back of the dirt slope to investigate, in short, when there is no stop, Wu Wu has had a nervous breakdown in the past few days, and he looks listless all day long.

"Let's wait another day, measure this area in the lower left corner first, so that we can have one more way out, and more circuitous paths. Feng Bo pointed to the corner of the map and said, as you can see, there is a clear incoherence.

"Isn't it just a short section of the subway sewer network? Don't care about these little things, if I continue to measure, I'm going crazy, big brother storm, you can't bear to look at me as a good young man, the future pillar will die before the master is born, and the little woman who will die first will be the hand of the villain and the woman?"

"Dead pervert, what are you talking about?" Just as Wu Wei was about to increase his strength to persuade the turmoil, a gloomy and sympathetic voice sounded in his ears.

"I mean, Xiaoting has been so tired in the past few days, she should take a break, otherwise she will be tired of our smart and lovely Xiaoting girl, so what should I do?" Wu Wei immediately changed his face, and his previous righteous indignation immediately became extremely flattering.

"Sure enough, if you are the lowest, you are invincible. The storm let out a sigh and immediately left this land of right and wrong, so as not to affect the pond fish when the time came to stage a full martial arts.

After a few days, the underground pipe network in this area has finally been calculated, some places have collapsed and blocked, while some places have countless cracks, the entire pipeline system has been unrecognizable, and even new blockages or cracks will appear every day, so some of the previous maps will only put themselves in danger, so every time you want to enter the underground pipe network, you must first measure, draw the latest underground pipe network diagram, and then you can enter.

The sound of ticking echoed through the empty tunnel, and the surrounding rock walls were covered with moss, and the whole tunnel was filled with a smell of decay, puddles and dots, and all kinds of filth wafting on them.

"Everyone be careful, now that we have entered the range of activities of the demon beasts, there are many demon beasts here who are very good at hiding, don't be curious, don't be careless, we just need to do a good job of defense, this is still the outermost part, there are generally no powerful demon beasts. Dong Feng reminded everyone that it was obviously not the first time he had come here and he had some experience.

The turmoil and Wu Wei and others were already very cautious, but when they heard Dong Feng's reminder, they focused their attention on some unnoticeable corners.

Suddenly, Feng Bo saw a puddle in front of him suddenly appear in a circle of ripples, and for no reason, Feng Bo began to condense an energy ball in his hand, but he saw that no one else paid attention, thinking that it was just his own illusion.

"What's wrong?is there anything wrong?" Seeing the movement of the storm, Wu Wei glanced around, but did not find anything unusual, and asked at the storm suspiciously.

"It's nothing, I just feel like the puddle is weird, as if something is staring at us. Feng Bo explained, pointing to the puddle that suddenly splashed and rippled.

Dong Feng also looked at the puddle, and then kicked a small stone at his feet, only to hear a plop, except for a splash, there was nothing abnormal.

The storm also saw the result, although there was still a trace of doubt, but he still said to everyone apologetically: "I'm sorry, maybe I'm too nervous, let's move on." ”

Just as everyone was about to set off again, suddenly, Wu Wei seemed to think of something, "No, there is something wrong with these puddles." ”

"What's the problem?" Feng Bo looked at Wu Wei while looking at the puddle that caught his attention again.

"You say that all these puddles have problems?" Dong Feng noticed Wu Wei's previous words, and then cautiously paid attention to all the puddles around him, and asked.

"Yes, don't you think that puddle is too deep just now? And these puddles next to them are too irregular, plus these gravel next to them, do you think that these puddles next to them are just formed by the small puddles left behind by some kind of demon beast attack? ”

"I think the pervert got it right this time, we should have entered the gathering place of the earth snakes. Xiaoting seemed to sound something, said with a hint of panic, and at the same time, subconsciously moved closer to her brother's side, looking for some security.

"Earth snake?" Storm was puzzled, there was no mention of it in the information gathered before.

"A strange snake that likes to burrow, when a prey appears near its burrow, it suddenly attacks to hunt for food, but the trouble is that this snake likes to live in groups, and each settlement will gather dozens or hundreds of ground snakes. Dong Feng explained.

"Then why didn't they attack us before, not even harassment. Wu Wei obviously hadn't heard of this snake either, and asked suspiciously.

"Each of these snakes has a leader, and the leader's burrow is built in the middle of the tribe, and once the prey enters the leader's hunting range, it is the moment when the hunt begins. Dong Feng still looked solemn, but he seemed to have thought of something, "Usually this kind of snake chooses terrain such as rock walls and canyons, why does it appear here, and there are so many of them." ”

"Since we won't be attacked as long as we don't reach the vicinity of the leader's cave, can we retreat now and exit this area?" Wu Wei asked tentatively.

"No, as soon as we retreat, they will attack, let alone retreat, even if they stay in place for a little too long. Dong Feng immediately denied, "And our map shows that there is only one way to enter, if we give up, we must re-measure the map, and we don't know what trouble we will encounter then." ”

"It seems that we can only go one way to the dark, since we can't avoid it, then we can only fight, since you have an understanding of them, while you still have time, let's introduce how this snake attacks and what weaknesses there are. When the storm heard Dong Feng's statement, he could only accept his fate, but he would never be able to do it.

"The snake's main attack method is the bite of the giant mouth after coming out of the hole, and the poisonous mist that erupts from its mouth. If it is a weakness, it is their ability to move, although they are snakes, but they are not good at crawling, their burrows are inverted funnel-shaped, they usually hover in their own caves, encounter prey, body strength, rely on instantaneous explosive power to hunt. That's all I know, and as for the rest, I can only see the tricks. ”

"It's quite a lot, according to the map, there is a fork in the road ahead, and according to you, if I am not mistaken, the lair of the Serpent King should be there. Everyone is ready to fight, don't get entangled, pass quickly, and then all choose the passage on the right, and everyone don't go the wrong way. Feng Bo said in deep thought, and then, after glancing at the circle of people, and seeing that there was no objection, everyone prepared for battle and moved forward.
