Li Sa looked around and replied: "The fortress they entered was built of this kind of stone in their memory, and the fortress was full of strange magic weapons. That was twenty years ago, and now it's hard to say whether this is a demon fortress with the same function. ”

"The fortress in front of us would probably have been abandoned if there were no demons." Ling Yu took a sip.

Lu Jingjing said curiously: "It's not easy for demons to build a fortress, isn't it okay if you don't want such a large-scale fortress in the distance?" ”

"If there isn't enough demon offerings, or if a place has its minerals mined, the fortress will be abandoned." Ling Yu said, "I don't forget who told me this, probably when I was a child, the clansmen said it casually. I have the impression that our tribe has merged with other tribes, and that the alien tribe has migrated from some abandoned fortress. The demon ruler over there is a human head and a fish body, and it is not too cold to swim in the ice sea, and the demon on our tribe's side is a human head and a horse body, with human arms and four horse legs. ”

Since Ling Yu wanted to go, Li Sa and the others would definitely not stop them. Waiting on the periphery is too passive, and they are still counting on finding enough parasites in the demon fortress to complete advanced hidden missions quickly.

Unexpectedly, Mr. Mei's side actually mobilized the strong team of Du Qinshan to stay behind. Among the school team of Guangyu Higher Xiuzhen School, everyone recognizes that the strongest is Du Qinshan's team, although Du Qinqin has become a left-behind person, there is one less person in their team, but the strength of four people is enough, Tong Zimin was also inserted, which is equivalent to having combat power and theoretical support, and being able to write and martial arts.

How did such a team choose to stay outside the demon's fortress?

Li Sa guessed that Teacher Mei might have other thoughts, what they had encountered in the past few days, and the black aura they were faintly emitting at the moment was very worrying. Fortunately, the black gas did not spread, and it still only stayed on a few of them.

But if something happens, Tong Zimin, a student who basically has no ability to protect himself, is afraid that he will suffer.

Li Sa tried to ask Teacher Mei: "Teacher, there is still one person left in our team, can you please ask Senior Tong to join us?" We're going to be behind the main attackers, and we're not weak in defense. ”

Tong Zimin didn't want to stay at first, but other teams didn't want to take him, a weak scholar. Now that Goddess Li Sali took the initiative to mention it, his heartbeat accelerated suddenly, and he took the lead in saying, "Teacher, I want to follow the attacking team to go in and have a look." There are so many different descriptions of the demon fortress in the classics, and there is still no unified understanding, and my research project also needs first-hand material in this area, so I want to see it with my own eyes. ”

"What if there's danger inside and there's a fight with the demons?"

Tong Zimin said: "Then I have to go, battles usually destroy the original environment, and the demon fortress may eventually turn into scorched earth, and there is no way to verify." ”

Teacher Mei saw that Tong Zimin was determined to go with Li Sa, so he didn't stop him, but just told him seriously: "If your defense can't support it, then withdraw first, it's not a shame." Everyone has a direction that they are good at, and if they can't run fast, survival is the most important thing. ”

Li Sa pretended to ask simply, "Teacher Mei, is there any danger in the demon's fortress?" The advance team said that no demons were found, and maybe we rushed in and picked up the leak directly, and the huge fortress was taken over by us. ”

Teacher Mei smiled bitterly: "The place where the demons are entrenched naturally has its own sinister places, you must not be careless about the enemy." By the way, don't get close to strange plants when you see them, when I went to rescue Du Qinshan and them before, I saw strange plants appearing in the deep pit, black fruit particles, scattered with black mist, and I am afraid that if I am contaminated, I am afraid that my life will be worried. ”

Li Sa could see this memory in Teacher Mei's mind, but although Teacher Mei immediately set up a protective barrier at that time, he still didn't prevent it. When he found the unconscious Du Qinshan and a few people, he also fainted quickly, and when he woke up, he specially checked the situation of himself and several students, and found nothing abnormal.

Originally, Teacher Mei's cultivation should have been able to see the black demonic qi lingering, but they couldn't see it, which showed that the demonic qi did have an impact on them. As for the impact, it is difficult to say at this time.

The attacking group of people uniformly obeyed the orders of Teacher Luo from the Zhongzhou Higher Xiuzhen School. Mr. Luo participated in the practice of sealing demons twenty years ago and retired with his whole body, at that time he was the elite selected by the school team, after twenty years of practice, his skills have been greatly improved, and he is recognized as the strongest and most experienced person.

Li Sa's school followed the attack this time are all people who have never been to the extremely cold place, and the leading teacher has been restraining the students of the school to keep a low profile, just try to follow along. After all, in terms of strength, Guangyu Higher Xiuzhen School as a whole is inferior to the well-known schools in Zhongzhou Prefecture.

Even if Li Sa has that "spirit beast", which can fly into the sky and attack strange insects with sound waves, it does not mean that she is strong in her own strength. Once the demon uses treacherous methods, those who are not cultivated enough may not be able to hold on to it by magic weapons alone. Therefore, they also acquiesced to let Li Sa's team break off, and once they found that there was danger, they would directly withdraw to the left-behind camp and bring back the latest news.

When this group of people rushed to the front of the demon fortress with great momentum, and found that there were no demons at the gate of the fortress and the watchtowers that seemed to be defensive around them, everyone still had some hesitation.

The shape of this fortress is to defend against foreign enemies, and there are also some records in the classics that describe the routines of the cultivators' elites storming the fortress and fighting demons, which now seem to be useless.

Pushing open the heavy stone gate of the fortress in three or two, everyone saw that there were corpses and bones all over the ground. Not fresh corpses, but a lot of bones. Most of these bones do not look exactly like humans, and fish tails can be seen, and four hooves can be seen.

These are the bones of demons.

Someone questioned: "Could it be that this fortress was breached by our predecessors twenty years ago?" ”

Teacher Luo said, "No, we deliberately chose another direction to enter the enchantment wall, this position we didn't come to twenty years ago. ”

"It must be the demons themselves, all dead, this place is abandoned." A few quick-witted classmates came to this conclusion and began to inspect the surrounding houses.

Li Sa sensed that it was very cold inside the demon's fortress, not as warm as Ling Yu had said.

Ling Yu obviously felt the same way, frowning slightly, carefully scanning the surroundings, and then fixed on the towering chimney in the center of the fortress. He said slowly: "When I was a child, I heard that there was usually a huge furnace in the demon's fortress, and from the outside, you could see a chimney more than ten feet high, emitting black smoke all year round. So it was very warm inside the fort, and our fire was brought from there. ”

Tong Zimin pointed to the chimney in the middle of the square not far away and asked, "Is that the demon's chimney?" There was no smoke, and it wasn't warm, no different from the ice outside. ”

"The forts I saw when I was a kid had chimneys that emitted black smoke, and the chimneys here don't smoke, maybe they are really abandoned." Ling Yu's words were not quite sure. It was strange that they hadn't seen the demon village on the way here.

The first shift on the weekend is the third watch
