Sure enough, it was a hidden mission, Lin Fei was fine, but the rest of the people were all happy. Hidden missions earn the merit points necessary to level up, and that alone is worth the risk.

It's not entirely dark either, with some cracks in the top of the head that allow sunlight to shine in, but it's of limited use. Fortunately, there are also some braziers around, burning with roaring flames.

"It's a fire oil made from burning demons in hell, and it can continue to burn for thousands of years!" After Lin Fei's instructions, Guo Bo ran over and touched the brazier, and then got the relevant information.

Using demons to boil fire oil is indeed a big deal.

"Get some torches and get those oil on them!" Lin Fei thought for a while. Among these people, they are the only ones who can see at night, so they must prepare such things as torches.

Soon, a few torches were made, and after being drizzled with that demonic grease, they began to burn.

Over there, Griswald was already walking towards the wall and the gate.

Walking to the door, Griswald actually took out a key, and then twisted the keychain that reached into the wooden door, and heard a dull sound of mechanism, and the door creaked open.

There was a fishy wind blowing in his face.

Lin Fei looked at the dark gate, but he was thinking about the details of this hidden mission.

This is also Lin Fei's habit, any task, hints are very crucial. Because at this time, the most information can be accessed is the task prompt.

And the hint for this task is quite simple. First of all, it should have a very long history, but why would a monastery be built underground?

Isn't the belief in the monastery a high heaven?

This guess was quickly confirmed, Lin Fei noticed that the relief paintings on the wall and gate were all kinds of terrifying and strange monsters, there was no doubt that Lin Fei's previous guess was correct.

And the quest hint also mentions 'an accident', so is there any connection between this accident and the current mission?

In addition, there are the conditions for the completion of the quest, one is to follow Griswald into the fourth basement floor of the monastery, that is, as long as you get there, you will complete the quest condition. This situation can generally be interpreted as an unimaginable danger on the road.

The second condition for completion is the liberation of the prisoners who were imprisoned here.

So, who are the prisoners?

Lin Fei had several questions, and it was obvious that he could not get them all answered at this time, so he could only make plans after entering this underground monastery. And at this moment, there was a terrifying dog barking in front.

The sudden sound in the silence of the environment is supposed to make people's hearts go crazy. The contractors are no exception. Everyone was startled, and as the sound approached, they saw several black shadows running out of front quickly, and when they looked closely, they turned out to be several black dogs the size of calves.

This black dog was pitch black all over his body, and he had no eyes, and his huge mouth was full of fangs, and his saliva was flowing all over the ground. Lin Fei gave the crossbow man a look, and the latter understood, but he took out the crossbow and raised his hand to shoot.

This kind of tentative attack has many advantages, one is to block the enemy, and the other is to detect the depth of the enemy.

Soon, the crossbowman said, "Level 15, Abyssal Hound, 3000 HP."

Everyone was shocked, level 15 monsters, and there were four of them as soon as they came out, so it must be a lot of trouble to deal with. Fortunately, as soon as the Abyssal Hound appeared, Griswald took the lead in rushing forward. Seeing this, Lin Fei hurriedly said: "Cooperate with Griswald to attack, white robe, depending on the situation, there is no opponent!" ”

The white robe nodded, and over there, Griswald and Guo Bo, the three flesh-shield-shaped figures of the animal skin were already fighting with the four abyssal hounds.

There was nothing to say about this battle, and everyone only felt that this level 15 monster really deserved its reputation. Not only is the attack power high, but the blood volume is also high, but fortunately, with Griswald, an absolute meat shield-type character, it is quite easy to kill the four hounds.

Four Abyssal Hounds dropped three pieces of equipment.

Shoulders of Immersion Iron, One-Handed Hammer of Fear of Immersion Iron, Mithril Shield of Immersion Iron.

It turned out to be a plate of armor, a one-handed hammer and a shield.

Seeing these three things, Lin Fei glanced at Guo Bo very strangely. In the forgotten tomb before, there was a heavy iron armor, and now there are three pieces of equipment marked by 'heavy iron', what is the unknown connection between this?

Lin Fei thought about it, but he was ready to assign all three things to Guo Bo. Since the death of his own stitched corpse soldier, there is one less absolutely powerful defensive warrior in the team, and with these three things, Guo Bo can be qualified for this role.

Guo Bo, who had already understood that his master was very generous, was shocked again. The attributes of these pieces of equipment were excellent, but some slave owners' equipment was not so good, so naturally he had a trace of gratitude to Lin Fei. It's just that he is not good at talking, and he can only show it with a desperate fight.

After killing the four Abyssal Hounds, the group followed Griswald into the Abbey.

There was a small garden with an iron statue standing in the middle, and when you looked closer, it turned out to be a female statue. This statue is lifelike, and although I don't know how many years it has been here, it is still easy to see what she looks like.

Others are fine, but the more Lin Fei looked, the more he felt that this female statue was familiar, and after thinking about it for a long time, he finally remembered it.

"It's the woman!"

In the forgotten tomb that Lin Fei and the others had accidentally found before, Lin Fei had seen this woman in a place surrounded by flames and smoke.

At that time, her eyes were pitch black, and black blood seemed to flow in her veins, and then she was weird, leaving a red crystal.

Lin Fei remembered this very clearly, because it was very weird. And now, Lin Fei unexpectedly found that the iron statue standing in this small garden was the same as that girl, except for the different clothes, the face was simply a person.

"Looks like there's a lot of connection to that forgotten tomb!" Lin Fei secretly said in his heart, but he didn't tell anyone about it. Because no one knew who the girl represented by this statue, Griswald might know, but Lin Fei didn't guarantee that the other party could tell him.

As we walked on, we came across several 'monks' in black robes.

Monk, level 15, HP 2500.

These monks are no longer human, but a kind of corrupted monster. They use magic to attack, making them very difficult.

To deal with this kind of monster, you must fight quickly, otherwise you are likely to be beaten by the opponent's magic and be powerless. As with all magical professions, the weaknesses of these monks are quite obvious. That is, he is not good at melee combat, so when dealing with this kind of monster, Lin Fei played a great role.

All the monks who were close to him, although their rank was much higher than Lin Fei's, they had no power to fight back. Lin Fei didn't even need to activate the Angel War Emblem, he could kill these monks with just a simple thief attack skill.

Similarly, these monks contributed some equipment after their deaths.

After entering a hall in front, Lin Fei and the others found that this place was actually not much different from the church outside. There are rows of chairs, candles, and very religious paintings on the walls. However, the difference is that the original painting of angels killing demons in the church has now been reversed and replaced by demons killing angels.

And all the candles were bright red, as if they were made of blood.

So far, the feeling that this monastery has given Lin Fei can only be described as weird. If this place believes in the demons of hell, then why would the demons be used to make lamp oil? If not, how could the painting be like this?

At this time, Alice, who followed Lin Fei, said: "The demons in hell represent all negative emotions, so there is absolutely no so-called order, they do whatever they want, low-level hell is fine, if it is a high-level hell such as Burning Hell, there is only killing all the time, and even between every primary demon and secondary demon is mortal enemies, and the battle between them is no less than the war between heaven and hell." This is also the reason why heaven that worships order can always prevail over hell! ”

After being in contact with Alice for a long time, Lin Fei sometimes forgot that she was also a demon clan, so he naturally knew more about this kind of thing than himself.

"This monastery believes in a certain demon in the high-level hell, but who it is is not clear!" Alice continued.

After everyone listened, they could be regarded as answering a little question in their hearts.

Of course, they don't actually care about these things, and the most important thing at the moment is how to complete this hidden mission and get rewards.

After a few more battles, we finally found a way down.

After going down the spiral staircase, you will reach the second basement floor of the underground monastery.

Previously, the enemies Lin Fei and the others faced were only Abyssal Hounds and a large number of cultivators, but when they arrived here, they were replaced by a kind of sharp-horned demon.

Sharp-horned demon, level 16, with 4500 HP, a pair of horns on his head, black skin, and a long sword full of jagged teeth, with extremely strong attack power. Guo Bo and the animal skin, who came into contact with these monsters for the first time, were almost killed in one move. Fortunately, these sharp-horned demons were tall, but their movements were slower, so Lin Fei let the crossbowman carry out a long-range attack. Fight in a distance-free way.

It's just that with the appearance of more and more sharp-horned demons, this trick obviously doesn't work.

When Lin Fei climbed a pillar and used his night vision ability to take a look, he scolded secretly. Because he saw that in the second underground floor, there were at least hundreds of such sharp-horned demons. And apart from dozens of thick pillars, there is basically no shelter here, like a hall, so if you fall into the siege of the sharp-horned demons, the consequence is only a dead end.
