The sound of the "boom" explosion echoed in the sewers, and in the light of the explosion, the sword was collected in a dashing manner, and at least twenty small battle puppets lay behind them. The four of them had been in the sewers for more than three days, and during those three days, they kept going back and forth down the pipe, searching for traces of the enemy little by little. Since Anne can only sense the presence of the soul's resentment but cannot sense the concentration, everyone can only follow the route that the other party has walked little by little, and cannot accurately judge the position of the other party in the recent time. However, fortunately, there are maid sisters here, and with their help, they can at least tell where they have searched and where they have not yet arrived, so that they will not pass by the same location many times. According to Catherine and Vivien's vision, keep searching at this pace, even according to the most pessimistic estimates, and search all the places that the other party has ever visited, and eventually find traces of the enemy. As long as you find the hidden location of the other party, and then quietly return the indulgence and enthusiasm, and take them down to raid the enemy, the mission of the adventure group is considered complete.

However, the past three days have not been easy, the number of puppets destroyed in the hands of Catherine and Vivian along the way is not less than four hundred, and now the maid sisters have seen the hideous puppets, they have changed from nervousness at the beginning to now ignorance, and in the end, if conditions permit, the two sisters even want to take out snacks and eat while cheering for the two professionals in the battle.

Of course, the actual battle was not so easy, the number of golems encountered at each time was not constant, at most fifty puppets appeared at a time, and for a while the surrounding area was full of metal grinding and the piercing screams of chainsaws turning. The maid sisters were ready for death that time, and they knew very well that Catherine and Vivien would have difficulty protecting themselves under so many puppet attacks, and it was impossible to have time to take care of their safety.

Fortunately, due to Catherine's advice before, the two did not run around at the critical moment. Instead, huddle together against the wall, silently waiting for the enemy to attack, ready to make a dying struggle, this choice just created a chance for Vivien to come to the rescue. Thereupon. Under the spell of Vivien's Ice Barrier, a thick, hard frost wall enveloped the two sisters, sealing them within the frost barrier, not only protecting them, but also insulating them from the breath of life. The metal golem that seeks out the enemy with the breath of life loses its target, and immediately loses interest in the extra lump of ice that has been created out of thin air. Turning all their attention to Catherine and Vivien, more than fifty metal golems swung their melee and mid-range weapons at the end of their arms, unleashing the most ferocious attacks on the two adventurers.

The battle went very strangely, not at all like the usual way that Catherine defended Vivien's onslaught of the two in the past, but the roles were completely reversed. Bounded by a one-meter circular area around the two of them, Vivien created a field of impact and maintained it with all her might, creating a safe space for any golem that came close to it to be bounced away by the sheer force of magical impact. And Catherine in the safe zone, in addition to constantly using her shield to block the crossbow arrows that were fired, focused on attacking. The one-handed sword always stabs continuously at the most opportune time, piercing the armor in the puppet's abdomen and completely destroying the puppet's central control.

Even if two to three swords can destroy the puppet, in the face of more than fifty puppets, Catherine almost consumed all her fighting energy, and almost collapsed to the ground after the battle. Although Vivien's task was lighter than Catherine's, its consumption was not lower than that of Catherine, and maintaining the impact field for a long time made Vivien's face pale and faltering, almost causing a temporary disorder of her magic and incapacitating her. Thankfully, both of them persevered, with only Catherine having five more minor injuries, while Vivien miraculously remained intact. I have to admit that this is already a perfect result. As for the maid sisters who were locked in the ice barrier and almost died of suffocation, it was just a small accident and did not affect the overall situation.

"Squeak". A few fat rats slipped past the feet of several young girls, quickly turned into a branch and disappeared. Immediately after him, a badger-like monster that was slightly larger than a domestic cat chased after him, also ignoring the four people in the process, and followed the mouse into the fork in the road.

"I think it's weird. Catherine looked at the fork in the road where the mouse disappeared suspiciously: "There are so many small animals and monsters here, what do they usually eat?"

"There's a lot to eat. Vivien replied, "These side roads are buried deep in the soil above them, and there is an abundance of food there. Well, at least it's abundant for mice. The rhizomes of various plants, all kinds of insects, and all kinds of fungi can provide sufficient nutrition for mice. Other carnivorous monsters can naturally feed on rats, forming a complete food chain. ”

"Poor bottom of the food chain. Catherine shrugged, "So, if anyone gets lost in this, maybe they can live forever." ”

"Well, I think so too. Vivien nodded: "The premise is that he can run faster than a mouse, his body can be harder than a clean puppet, and he can endure a long period of loneliness without letting the environment drive him crazy." ”

"Shhhh Catherine abruptly interrupted the meaningless nonsense between the two, and used her vindictive-enhanced hearing to distinguish the surrounding voices in the air: "I vaguely hear voices ahead. ”

"It's normal to have a sound. Vivien said nonchalantly, "Didn't you hear about the cleaning puppets that were alarmed by other demonic beasts yesterday, thanks to them to cover up our voices." ”

"It's different, this is not a fight, it's a weird sound. Catherine frowned and said, "It's kind of like the tooth-aching sound of something metal breaking and moving back and forth." ”

"Well, dear eldest sister, you don't need to describe it so vividly. Vivien rubbed her arms and grinned, "I feel sick just thinking about it, why don't we go over and see what it is?"

"There's undead creatures there. Anne suddenly came out again, pointed to the branch pipe facing everyone, and said, "I feel it, there are a lot of undead there, but the distance is far away, and the location is quite scattered. ”

"Anne, you're feeling it. Catherine said, "Has our target been there?"

"No, I don't feel the smell of them," Anne hesitated for a moment, shook her head, "but I feel like there's something special over there...... Hmm, it's too far away, it feels too vague. ”

"Something special?" Vivien thought for a moment and asked Anne, "Is it important to you?"

"I don't know, I just think it's a little special. Anne shook her head: "It's too far away to figure out." ”

"Forget it, let's go for now. Catherine thought about it for a while, but gave up the idea of exploring: "Do the business first, if you really care, wait until the business is done and then find a chance to take a look, now that Lina is not here, there is no need to conflict with the undead." ”

"But, Sister Catherine. Anne tugged at Catherine's arm: "There are undead in the first few roads." ”

"Huh?!" Catherine and Vivien were stunned at the same time: "Both?"

"Yes, those people have passed this road. Anne pointed to the other widest main pipe, "But there are undead in front of this, and there are many of them." The other roads don't have the smell of those people, but they also have a lot of undead. ”

"It's a nuisance. Catherine sat down with a headache and waved to the others: "Sit down and rest for a while, and study what to do." ”

"There's only one way, and no matter what you say, you have to go down. Vivien opened the water bottle, couldn't wait to fill half a bottle of water, licked her somewhat dry lips and said, "Since you have decided to use this kind of investigational search method, you must not let go of any possible location." Otherwise, if we go around here and look elsewhere, in case they are hiding here, then we will never find them in our lives. ”

"But there are so many undead in front, how can they pass through the large crowd of undead?" Catherine shook her head, "I prefer that they once tried to pass through here, but because they were attacked by a large number of undead and had to withdraw and find other paths, so there are so many pathways in this area we explored before that have their grudges." ”

"But......" Vivien was about to speak, when the ground beneath her suddenly shook slightly, and a faint roar continued, coming down the pipes of the underground waters, and the sound seemed not far away.

"What is it?" The two adventurers jumped on the spot, staring solemnly at the direction from which the voice came: "It seems to be a big guy." ”

"The roar was like footsteps. Catherine said with a somewhat ugly face: "The vibration is similar, but how can there be something in the sewer that can make such a footstep sound? ”

"It's fine if it's a Warcraft. The corners of Vivian's mouth trembled and said, "In case a metal puppet is miserable, a metal puppet that can make such a sound may be larger than we imagined." ”

A prompt sound of "drop" sounded in the pipe two or three hundred meters on the side, and a mechanical goblin whisper that the four people had heard many times sounded. This time, the completely incomprehensible language was different from usual, and it seemed to be pronounced while moving, and listening to the sound get closer and closer to the position of the four people.

"It's coming for us. Vivien and Catherine looked at each other, "I guess so." ”

"There's no way, let's slowly retreat first. Catherine stood in the last position: "Since there are undead all around, let's retreat to the same path where our target has been, and see if we can avoid this big guy." ”

It turns out that sometimes the idea is good, but the truth always makes some jokes with people. The slow retreat of the four people did not allow the object that made a loud footstep sound to shift its target, and the other party seemed to recognize them, and walked down the pipe towards the four people without any deviation.

"It's coming. Catherine, who had slowly withdrawn nearly a hundred meters, stared at the branch pipe where footsteps came, and saw a huge figure slowly turning out of the pipe.
