If this is the case three times, there is only one hilt left in the sword in Xiao Tian's hand. Wu Song flashed in front of Xiao Tian, pointed at his acupoint, and said, "Xiao Tian, listen to me, your father really wasn't killed by me." ”

"You didn't kill it, who killed it? You were the only one in the room. "Little Heavenly Dao.

"Your father went to the next room to give me a copy of the map, and someone broke down from the roof of that room and killed your father. There's a hole in the roof, and if you don't believe me, I'll show you now. Wu Song said.

"No need," Xiao Tiandao said, "the people in the government have already discovered the hole, and they said that it was used to escape after you killed my father." ”

Wu Song said, "If it was really me who killed your father, no one knew at that time, I could have left the main gate in a straight and bright way, why did I make a hole?"

Xiao Tian pondered for a while and said, "Who is the person who killed my father?"

Wu Song said, "It's a sect called the Golden Crow Sect, and they are here to snatch a map from your father's hand. Listen, Xiaotian, if you want to avenge your father, you must join forces with me, so that you can hope. ”

Xiao Tiandao, "I believe in you, I'm sorry, I was reckless just now." So what do we do now?"

Wu Song said, "I have to leave the undersea city as soon as possible, but now that the whale has been controlled by the Golden Crow Sect, I need to leave here in another way."

Do you know where the membrane that wraps the city is stored?"

Xiao Tian thought for a moment and said, "There seems to be a book in my father's study that mentions the storage place of that kind of film, so let's go there and find it." ”

At this time, after a day's investigation, all the people in the government left the study. Wu Song and Xiao Tian easily entered the study, and Xiao Tian began to rummage through the bookshelves.

Wu Song waited for Xiao Tian and accidentally saw a wall next to him full of various antiquities.

Before, when Wu Song came here, he saw these antiquities, and he didn't pay much attention to them at that time. Looking at those antiquities now, Wu Song's heart suddenly moved.

Those antiquities were obtained from the local area when the master was surveying various places. Underneath each antiquity, the place and time are marked.

After Wu Song looked at all the antiquities, he found that those antiquities basically came from six places.

Moreover, all the antiquities were collected only a year ago.

Previously, the master said that he had only realized the correspondence between the sun and moon in the sky and the earth a year ago. Then, he began to explore the Xuanwu Realm, looking for a place that corresponded to the sun and moon in the sky.

Then these antiquities should have been taken from places where the masters thought they might correspond to the sun and the moon.

These artifacts come from six places, and the previous master said that he had identified four possible places, and the places corresponding to the sun and moon were in those four places.

In other words, the master went to these six places, and after investigation, he excluded two of them, and then came up with four places.

In other words, although the map has been snatched away by the Golden Crow Sect, the origin of these antiquities has already provided Wu Song with a possible destination.

Thinking of this, Wu Song couldn't help but feel happy in his heart.

"Brother Wu, I found it. Xiao Tian over there held a book and said.

It was a very thick book, Xiao Tian opened it, turned to a page, pointed to a line of words on it, and said, "Look, isn't this it?"

According to the book, the kind of film that wraps the underwater city is stored in a warehouse in the south of the underwater city.

The above also describes in detail how to use the film, including the cutting method. The film is so tough that it cannot be cut with a knife, etc., so a special drug must be applied to the knife.

And the recipe for that drug is also well documented above.

In the master's study, there are a lot of medicines. Wu Song has a thousand prescriptions, and the use of drugs can now be described as a big family. Soon, Wu Song used the medicine in the master's study to prepare what he needed.

Then, Wu Song left the master's mansion and hurried to the warehouse in the south of the city.

That warehouse was the place where the government stored important things, and it was naturally heavily guarded. Moreover, the shape of the warehouse is very peculiar. It is a spherical structure, mostly suspended in the air, supported only by a thick pillar at the base.

Moreover, the entire building was built on a lake.

Wu Song circled the entire building in the distance, but found no place to sneak into.

And outside the warehouse, there are three layers of guards. There was no doubt that there was a layer of guards inside the warehouse, although Wu Song didn't see it.

Outside the warehouse, there are two two-story guards.

So the guards, combined, Wu Song estimated that there were about thirty.

With so many guards, Wu Song obviously couldn't defeat them all. Moreover, once these guards are attacked, they will inevitably ask for help from the city government, and the number of reinforcements will be far more than thirty.

Wu Song looked at the warehouse and frowned. In every sense of the word, it was an impenetrable fortress.

Wu Song returned to his hiding place, and Yun Rong sensed Wu Song's frustration and said, "What happened?"

Wu Song said, "It's nothing, it's just that we may not be able to get out of here anytime soon." ”

Yun Rong said, "Then let's wait, we will always think of a way." ”

Wu Song smiled slightly and looked at Yun Rong gently. I don't know why, no matter how depressed he is, as long as Yun Rong comforts him with a word, his mood will improve.

Wu Song suddenly thought of something and said, "Yunrong, you stay here for a while, and I'll come when I go." ”

Wu Song came to the exit of Zangsha City and hid in the nearby woods.

A hole was blown out of the exit by the Golden Crow, causing seawater to pour in. Although it is now blocked by a door, the sea water does not flow into the city. But this situation obviously cannot be sustained, and the government will definitely repair the hole as soon as possible.

Then, to repair the hole, you need to use that kind of film, and then at the exit, you can find that kind of film.

The warehouse was heavily guarded, and Wu Song could not enter. But at the exit, there will definitely not be so many guards.

Sure enough, at the exit, a bunch of people gathered. And in the seawater, there are several other people, who are in the hole, and seem to be measuring the size of the hole.

Next to the pile of men, there was a carriage, which was guarded by a group of soldiers.

Wu Song estimated that the membrane was in that carriage.

The next thing is to find a way to get into the wagon there and steal that membrane out.

Not far from the wagons there, piles of timber were piled up, presumably materials used to rebuild the exit.

Wu Song secretly came to the side of the pile of wood, activated the phoenix chirp, and ignited a piece of wood on the bottom floor. Afterwards, Wu Song hid in a bush of flowers and plants not far away.

Soon, the whole wood was burning, and billowing smoke came out.

The crowd over there immediately became noisy and immediately ran towards here.

Half of the guards guarding the carriage also went to put out the fire.

Wu Song took the opportunity to sneak to the side of the carriage, suddenly rushed out, launched the Celestial Elephant Fist, and rushed into the guards.

Those guards were Wu Song's opponents, and soon, they were knocked to the ground by Wu Song.

Wu Song got into the carriage and saw a wooden box one meter square. When opened, the wooden box was filled with a transparent liquid that emitted a pungent odor. In that liquid, there is a transparent film.

This is what Wu Song is looking for.

Wu Song clamped the wooden box under his ribs and got out of the carriage.

At this time, the other guards had already discovered Wu Song, and they all ran here.

Wu Song ran into the woods next to him, and the guards chased him into the woods, but he was quickly thrown away by Wu Song.

Wu Song returned to his hiding place and said to Yun Rong excitedly, "Yun Rong, I got what I was looking for." ”

Yun Rong wrinkled his nose and said, "I smell a pungent smell, what is that?"

Wu Song said, "This is something that can help us get out of here." ”

Wu Song took out that kind of film, he was worried that the film in the wooden box would be relatively small and could not be made into a container that was enough to wrap both him and Yun Rong, but now it seemed that he was too worried.

The membrane is very thin and light, and when unfolded, it is three meters square.

Wu Song found a few iron bars from other places, launched the Feng Ming Jue, and welded those iron bars together to form a cage with a radius of two meters.

Then, he draped that membrane over the cage and wrapped it tightly.

This is the cabin where Wu Song is about to leave the underwater city, and when the time comes, he and Yun Rong will sit in it and float to the sea together.

But then, Wu Song thought of a difficult problem. That's where they should leave, the whole city of the undersea city is wrapped in that kind of membrane, and only in the two places of exit and entrance, can there be access to the sea.

Of course, Wu Song could use the prepared special medicine to make an opening in the membrane in any place in the undersea city, and he and Yun Rong entered the sea from there.

But when the two of them are gone, the sea water will pour into the underwater city through the breach. If the government fails to plug the breach in time, then I don't know if any of the residents of the undersea city will die in the flood.

Thinking of this, Wu Song decided not to bring possible disasters to the residents of the undersea city.

The exit, which at this time was already flooded by the sea, could not go there. The only place Wu Song can go is the entrance.

The question was, how could Wu Song carry this iron cage into the entrance without being caught by the guards there.

The only way to do that is for someone to lure the guards out of the way.

Wu Song thought about it and thought of one person, that is, Xiaotian. In this undersea city, there is no one to help him except Xiaotian.

Zhang Yu was willing to help him, but he didn't want to involve Zhang Yu.

Wu Song went to the master's mansion, found Xiaotian, and explained his intention.

Wu Song said, "Xiaotian, you are the son of the master, even if you are caught, you will be fine." ”

Xiao Tiandao, "Brother Wu, don't say it, I'm willing to help you." I only hope that when you get outside, you will catch my father-killer and avenge me. ”

Wu Song said, "Don't worry, even if you don't say it, I will destroy the Golden Crow Sect." ”
