The addition of you living people has only to disrupt their cooperation and affect their battles. ”

Wu Song said helplessly, "Okay, since that's the case, then listen to your arrangement." ”

After Musa left, Mu Ling took Wu Song and them to the guest room.

There were two wooden houses, and when the wood spirit opened the door, a musty smell wafted out of the house.

The room was covered with dust, and there were some damaged weapons and other objects piled up in the corner.

Mu Ling said apologetically, "We never expected outsiders to come, so we didn't prepare a guest room. This is an abandoned warehouse, and it is the only one that is currently idle, so I have to grieve you. ”

Wu Song said, "It's okay, we have been sleeping all the way, and it is already good to have a room to sleep in." ”

The next day, Wu Song woke up early.

According to the hour, the hour has not yet come, and the sky should still be black. However, due to the magma everywhere in the Purgatory Lands, the firelight has turned the sky red.

Wu Song walked under the city wall and walked around the city wall.

Earlier, Wu Song only saw that the city wall was red, and speculated that the city wall should have been built with local rocks and earth.

Standing close now, Wu Song realized that this was not the case. There are no traces of brickwork on the walls, it looks more like a single block of rock, and the surface is very flat.

However, Wu Song did not believe that this city wall, which was dozens of meters high, was a complete rock.

It is impossible to have such a big rock, and even if there is, it cannot be moved with the power of the human race or the power of the demon race, let alone build a tall city wall based on it.

So what's going on here?

"Isn't it unbelievable?" Wu Song was watching from the side of the city wall, and the voice of the wood spirit suddenly sounded behind him.

Wu Song turned his head to look, and Mu Ling walked over.

Wu Song said, "Why did you get up so early?"

Mu Ling smiled, "I kept vigil last night and didn't sleep at all. His eyes were bloodshot and his face was tired.

Wu Song said, "But isn't it two days later that the sorrow will come, why are you so nervous now?"

Mu Ling said, "This is a habit, in the sixty years of sleeping, every one of us is like this, and we dare not relax in the slightest." Because what we are guarding is the most important thing of the demon race, the origin spar.

We don't know if the Wanderer will suddenly break through the seal and attack the Origin Crystal. We only know that if the Origin Crystal is destroyed, then the entire demon clan will face the end of the world.

Therefore, we dare not slack off. ”

Wu Song sighed with emotion, "You are really a group of heroes, but almost no one on the Xizhou Continent knows about heroes like you, which is really unfair." ”

A flat smile appeared on Mu Ling's face, and he said, "There's nothing unfair about it, we do these things just for the mission on our shoulders, not to gain the worship of others. ”

Wu Song said, "I really hope I can fight side by side with you, but unfortunately the patriarch doesn't allow it." ”

Mu Ling said, "You don't belong to the Guardian family, so you don't have to risk your life. ”

Mu Ling walked to the side of the city wall and said, "You were looking at this city wall carefully, were you surprised by it?"

Wu Song nodded, "From my shallow knowledge, this city wall should be a whole rock, but if you want such a big rock, you have to dig it out of the mountain as a whole."

This kind of work, judging from the current strength of the Xuanwu Realm, neither the human race nor the demon race can do it. So, it's incredible. ”

Mu Ling smiled, "When I first saw this city wall, I also had the same infinite emotions and doubts as you. I marveled at the majesty of the wall, marveled at its magnificence, and wondered how it was built, just like you.

Later, I learned from my parents that this wall, as well as this fortress, was left over from ancient times. The fortress existed before the arrival of the first generation of Guardian families.

We just built on it and did some expansions. ”

"The Ancient Ten Thousand Clans," Wu Song muttered, "this place should have been built by the Ancient Ten Thousand Clans. What kind of race are the ancient races, and why can they create so many incredible creations. ”

Mu Ling said, "Have you come into contact with many creations of the Ancient Races?"

Wu Song then described the creations such as flying spars and flying ships to Mu Ling. He drew out his Dragon Eclipse Sword and said, "This is a weapon that recognizes the master, it can be the same as the master's soul, it is extremely powerful, and it is also made by the ancient races. ”

Mu Ling exclaimed, "It's really a race like a god, why would such a powerful race become extinct?"

Wu Song said, "I don't know, but it is possible that the ancient ten thousand races will be resurrected soon." ”

Wu Song told Mu Ling about the Golden Crow Sect and the Jade Rabbit Sect, the corresponding places, etc., and after hearing this, Mu Ling's eyes widened in shock, and he said, "If the ancient ten thousand races are resurrected, then the entire Xuanwu Realm is estimated to undergo earth-shaking changes. ”

Wu Song bowed, "Yes, so although the ancient races were divided into good and evil, no matter which side they are, I don't want them to be resurrected." ”

At this point, the sun has risen. The soldiers who were on the night vigil on the city wall had finished their shifts, and they all came down from the city wall. They passed by Wu Song and Mu Ling, and greeted Mu Ling one after another.

Mu Ling said, "Let's go, I'll take you to the city wall to have a look." ”

The walls are forty-nine meters high, and there are two ways to get up. One is along a zigzag stone staircase, and the other is up from a cage that rises up and down.

The cage was fast, but in order to better feel the majesty of the city wall, Wu Song and Mu Ling went up the stone stairs.

The two came to the top of the city wall, and when Wu Song passed through the door hole yesterday, he calculated that the thickness of the city wall was at least ten meters according to the length of the door hole.

Now standing on the top of the city wall, Wu Song found that the width of the top was about fifteen meters.

The defenders extended several more meters outward at the top of the wall to allow more soldiers to move on it.

The top is divided into two roads from the middle. One road for cavalry and one road for infantry.

Wu Song came to the pheasant moat of the city wall and looked outside the city wall.

At a height of almost fifty meters, what is on the ground has become much smaller.

When Wu Song and the others passed by the ground outside, he had seen a demon beast white bone more than three meters high, and he thought it was very huge at that time. And now, the white bone looks like a toy.

Wu Song had a question, he asked Mu Lingdao, "What do those people look like? Do they have huge bodies?"

Mu Ling understood what Wu Song meant, and said, "The size of an adult is three to five meters, and it can be regarded as a giant beast. They have sharp claws and can run around walls with ease.

Therefore, I think that the reason why the ancient tribes built the city wall so high in the first place may be to leave enough time for the defenders to deal with the terror of climbing the city wall. ”

Wu Song groaned, after seeing such a majestic city wall, he felt that it was extremely difficult for him to break through the city wall.

However, if he can run freely on the city wall, as Mu Ling said, then it is a different matter.

For a three-meter-tall beast, running a distance of fifty meters is just a matter of an eye.

From forty meters, dense iron spikes stretched out from the city wall, and the spikes rushed down, presumably to defend against the troll.

Wu Song and Mu Ling walked along the city wall, and every ten meters each, Wu Song saw several wooden barrels more than one person high. There is a deep grease stain on the outside of the barrel, and when you get close to the barrel, you can smell a pungent smell.

Mu Ling said, "These barrels are filled with a kind of black oil, which will burn violently when it encounters an open flame.

If we climb the walls in large numbers, then we will pour this black oil down and disrupt the communication between them. ”

Wu Song said, "Didn't the taos come out of the magma?

Mu Ling said, "They are not afraid of fire, and the purpose of using black oil is not to harm them, but to use the noise generated by the burning of black oil to disrupt the communication between them.

There is a very important reason why they are so powerful, that is, they will cooperate with each other.

The snort will make a cry to tell his partner what to do. This makes them as powerful as a well-trained army.

If you can disrupt the connection between them, then they will become a mess of sand, and it will be easy to deal with. ”

Wu Song said, "I see. ”

After taking a turn on the city wall, Wu Song had a general understanding of the arrangement of the defenders. The general feeling is that the defenders are experienced, and they have a way to deal with the problems that Wu Song thinks of.

When he came down from the city wall, Wu Song felt much more relieved.

Previously, he had feared that the defenders would not be able to hold the fort, leaving him and the others under attack by the Devil. Now, Wu Song's doubts have basically been dispelled.

Then Mu Ling and Wu Song went down the city wall, Mu Ling went back to his room to rest, and Wu Song walked around the fortress.

At noon, Wu Song returned to his residence and told the others what he had seen and heard in the morning.

After listening to this, everyone felt a lot more relieved like Wu Song.

At lunchtime, the defenders provided food to Wu Song. The Purgatory Land is divided into three layers, and the first two layers Wu Song they have seen before, it can be said that there is no grass.

But the third layer, the core of the Purgatory Lands, is not the same as the outer two layers.

Although there are volcanoes in the third layer, most of them are extinct volcanoes, and apart from the occasional eruption of smoke, there is basically no movement.

The temperature in the third floor is also much lower than in the outer two, so there is some life inside.

There were some plants and beasts that grew, and the food for the defenders was partly cultivated in the fortress on their own, and partly from the third layer.

While eating, Wu Song found that the spirit rhino beast was gone. The little one is small, but he eats a lot. It's one of the most excited people when it's time to eat.

Wu Song asked the others where the spirit rhino cub had gone, but no one knew. The spirit rhino cub usually likes to run around, and no one pays attention to when it doesn't notice.

Wu Song didn't care, and after lunch, he continued to wander around the fortress.
