Li Mang endured the discomfort in his heart and once again used the law of light to attack the sea beast, but the sea beast also shrank into a ball again and resisted this blow.

"Whew"

After the blow, the sea beast's blue blood flew and its mouth screamed in pain, and then it fled into the distance, as fast as lightning.

Li Mang didn't expect to be able to deal with this disgusting monster so easily, although he didn't kill it, but the mission was completed.

Li Mang comforted Lihua in his arms, and when he was about to leave, he inadvertently saw a ray of light from the sea beast's habitat just now, but it was instantly covered by some raised sea debris.

When Li Mang was looking into the depths, he heard the familiar mechanical female voice in his mind come again: "Congratulations to the player, you have found the treasure spot, and you are searching... Treasure map is being automatically generated... The treasure map is in your backpack and you can go and view it yourself".

"Treasure map?"

Li Mang was pleasantly surprised, hurriedly opened the backpack, went to the last page, looked at the treasure map, and then clicked to use.

I saw that the treasure map was still rotating and enlarged as before, and finally turned into a plane map, and the red line finally reappeared, guiding the direction.

Looking along the red line guidance, it was really the place where Li Mang found that light just now.

Li Mang didn't think about it and took Lihua down, and in the blink of an eye, he came to the place of light, and then the mana in his hand spewed, and those sea debris were raised again, and finally revealed the light.

"Is there room under the sea?" Li Mang muttered to himself, and then used his fist to smash it towards the light below.

"Poof"

After a muffled sound, the light continued to amplify, and the originally clear sea water turned muddy.

"Ahh Li Mang, what are you doing" Lihua was also shocked by the turbidity in front of her at this time, and exclaimed in disgust.

"Don't talk, follow me," Li Mang scolded, and then pulled Lihua and rushed towards the bright hole.

Penetrating the soil layer at the bottom of the sea, there was a huge city in the eye, and the city was actually made of the so-called 10,000-year-old ice core stone, which was really shocking.

"It's... This is..."Lihua also saw everything in front of her at this time, and said dumbfounded.

After a brief shock, he followed the guidance of the red line and rushed to the city, only to see that the city was full of snow-white color, the streets were crisscrossed, the houses were lined up, and everything was intact.

Li Mang first walked to a room at random, and it took a lot of strength to push the heavy ice door open, only to see that there was nothing else in it except for some stone tables and chairs, and the rest of the rooms were the same.

After Li Mang's heart was clear, he obediently followed the route guided by the red line and acted quickly.

In a short time, the two of them had already passed through the entire city, and came to a majestic building like a palace, Li Mang looked at the red line again and stepped into the palace gate.

The map changed again, from a large topographic map to a close-up map, and the red line resurfaced on it.

"Have you been here?" Lihua felt as if he knew the road here, and it was quite smooth.

"Naturally, it's the first time I've come, just because I got the treasure map of this place by chance" Li Mang's mind was all on the map, casually coaxing Lihua Dao.

After a long time, the two of them meandered through the huge palace for a long time, and finally came to a slightly holy main hall. The inside of the hall, just like the outside, is completely paved with 10,000-year-old ice core stones, but the decoration in the hall is exquisite and luxurious, and it is naturally all snow-white.

"Limang, each of these things looks like perfect crafts," Lihua said, pointing to the bottles and cans around her.

"If you like, take some out, I'll put a protective shield around you, you can turn around yourself" Li Mang said with a wave of his hand, and the colorful breadth suddenly wrapped Lihua, and he himself walked towards the white stone chair in the middle of the main hall.

The map turned into a close-up navigation as soon as Li Mang stepped into the main hall, and the red arrow pointed to a long white case behind the stone chair, with nothing on it except tribute and incense burner.

Li Mang walked closer, groped on the long case, and finally gently moved the incense burner, and when he saw that there was still nothing special, he began to fiddle with the tributes.

The tributes have long been frozen, and there is no way to see the type at all, but after Li Mang just took all the tributes out of the plate, he suddenly opened a door after seeing the long case, and Li Mang was startled and didn't care to greet Lihua, so he rushed into it.

Lihua was also startled when she heard the sound, and was about to follow Li Mang in, when she saw that the stone door closed quickly and returned to its original state. After a shock, he glanced around in fear, and then stood in front of the long case and waited, his face full of helplessness and panic.

said that after Li Mang entered the secret room, he was also startled by the suddenly closed stone door, but then he was completely affected by the vacuum state of no drop of sea water and air in the secret room.

There are two bookshelves against the wall in the secret room, and the books on the shelves are well preserved, and there are dozens of them. There was a desk in front of the bookshelf, and there was nothing but a piece of paper on the desk.

Li Mang gathered his mind, then picked up the paper and watched it, but after a rough look, his expression changed greatly, and then he looked at the place of payment in shock, and said to himself: "The Bai family in the Eastern Continent."

Undoubtedly, the owner of this undersea city, the Bai family, is the same era as the predecessors of the Feng family in the nine-story trial pagoda, and the letter actually gave a detailed explanation of what happened after the war ten thousand years ago, and the content of the letter was very involved, no wonder Li Mang's face changed drastically.

Li Mang carefully folded the letter and put it in his backpack, and then walked towards the two bookshelves.

The Bai family has a long history of inheritance, and in addition to a few Shenzhou history books written by the ancestors of the Bai family and a detailed explanation of the four continents on the bookshelf, it is the secret of the Bai family. These include heaven-level exercises, techniques, cultivation experience, the way of alchemy, the way of formation, the way of the beast, etc., this harvest is more precious than what Li Mang obtained in the nine-layer trial pagoda, because of the detailed description and elaboration of the heaven-level realm after the tribulation realm, and also made Li Mang more clearly understand everything in the four continents.

After putting away everything here, Li Mang looked around and saw that there was nothing missing, and then according to the words in the letter, he opened the mechanism and returned to the main hall.

"Li Mang, why did you just come out, I'm so scared" Lihua saw Li Mang appear, and immediately pounced, and said with a trembling body.

"I was also brought in by accident, I thought there would be some good things, but I didn't think it was too old, everything in it was gone, hey" Li Mang comforted Lihua and looked at the treasure map in his mind again, seeing that the red line in the treasure map really disappeared, and all the treasures that wanted to come here were obtained by Li Mang.

"Didn't get anything?" Lihua raised her head when she heard this, and looked at Li Mang suspiciously.

"No, I don't believe you can go in and take a look yourself, there should have been some books inside, can books survive in this cold deep sea?"

"Alright then, let's get out of here, I don't want to stay for a quarter of an hour," Lihua said, still trembling.

In the depths of this vast sea, in the dead city that has sunk for I don't know how many years, in addition to loneliness, it is lonely, can it not make people afraid?

"Well, I can't leave anything in the meantime, and these bottles and cans are still worth some money, do you want to take some with you?" said Li Mang with a smile.

"No, it's just a foreign object, and it's not a treasure" Lihua didn't even dare to reply, and said categorically.

"Okay, then let's go back the same way, but there is one thing, don't talk about everything here, you know and I know," Li Mang explained to Lihua.

"Okay, okay, let's go," Lihua nodded and said.

Li Mang smiled, then pulled up Lihua and walked out, along the path straight out of the palace, and then out of the city, and finally found the hollow, but the hollow was blocked by the sea debris again, think about what formation exists in the sea above the city, right?
