The three of them headed towards the center of the lake and continued their dive.

The diving limit of ordinary humans is more than 100 meters, but the limit of martial artists can reach 2 or 300 meters.

However, on Earth, humans with special equipment can already dive into the deep sea of thousands of meters.

However, humans are still not as good as marine species, such as sperm whales, which can dive to more than 2,000 meters of water.

After diving to about one hundred and fifty meters, Zi Yun began to feel a little tightness in her chest, Zi Su used her free hand to relieve her pressure, as for him and Yu Feng, they did not feel any discomfort yet.

Ziyun pointed to a flat black and purple rock wall in the water and said: "Young master, here's the place to open and close the main gate of the mechanism, see no, there is a hole there, you can insert ~ into the Zixia Order, turning counterclockwise is to close the mechanism, and turning clockwise is to open the mechanism." Oh, by the way, when turning, you must inject Zixia True Qi, otherwise it will have no effect. ”

The perilla looks very smooth on the rock wall, and it can still be maintained in the water after so many years, indicating that the rock wall must have been coated with some kind of special coating.

"yes, I see. "Zi Su took out the Zixia Order from the martial soul space and tried to insert it into the hole~, but it turned out that there was a foreign object in it, and it could not be inserted smoothly~in, he pulled out the Zixia Order, cast the dragon's blood subject palm to suck all the foreign objects clean, and then inserted it, and then inserted it to the end, Zixia Ling only left the handle outside, he held the handle and cast Zixia True Qi to try to rotate counterclockwise, it was a little difficult to rotate at first, and it was easy to turn away, when it turned to three hundred and sixty degrees, only to hear a click, as if there was a mechanism locked inside, and then Zixia Ling couldn't turn.

"Alright, the main gate has been locked, let's go down and find the entrance. Zi Su said, pulling out Zixia Ling.

The three of them continued to dive, Zi Su was worried about Zi Yun's body, so when he continued to dive, his hand pressed behind her ears and chest from time to time to relieve the effect of water pressure, and when it was almost 220 meters, a hole that only allowed one person to enter appeared, and the fresh stones around it fell off, which was undoubtedly just opened.

"I'll go in first, Yun'er will follow, Fengfeng Palace. After Shisu finished speaking, he took the lead and entered the cave.

Don't look at the narrow entrance of the cave, but the passage in the cave is suddenly open, much bigger, Shisu waited for a while, and the two women also entered it.

The three of them swam together, just turned a corner, suddenly there was a strange sound in front, and the water also had a strong spiral nest, Shiso's perception was the most sensitive, and he suddenly saw a big blue-green python in front of him, with the thickness of a thigh, and a length of more than ten meters, swimming quickly towards the three of them.

Women are basically afraid of snakes, Ziyun hurriedly hid behind Zi Su after seeing it, but Yu Feng was an exception, she took out the bronze man, and opened her mouth at the blood basin of the python, which was a mess, the teeth and mouth of the python were smashed to a pulp, and the pain made it roll violently, and Zi Su took out the dragon sword at this time, slashed through its abdomen, peeled it off, and then the tip of the sword was lightly picked, and a crystal inner dan was picked out, at this time Yu Feng's bronze man smashed to the snake's head and smashed its head to pieces.

"Come, Yun'er, swallow this Neidan. ”

"If you don't swallow it, it's disgusting. ”

"It's not disgusting, it's fragrant, you smell it. ”

Ziyun got closer and smelled it and found that there was indeed a strange fragrance, so she swallowed the inner dan of the python with a nauseous feeling, and soon the inner dan had an effect in her body, and she found that her chest was no longer stuffy, and her ears were no longer roaring.

"Yun'er, this Neidan is at least a hundred years old, as long as you continue to absorb this power, it is completely possible to break through to the Martial God, of course, the most important thing is to have a corresponding improvement in spirit. ”

"Ah, this Neidan is so powerful, I knew that I wouldn't take it, how good it would be for the young master to take it." ”

"Young Master, even if I don't cultivate my skills, my strength has grown very quickly, where can I use it to take the Inner Pill. ”

"That is, with Brother Zisu's dragon blood spiral, the speed of absorbing the aura of heaven and earth is dozens of times that of ordinary martial artists, and the effect of taking Neidan is not great, and Ziyun is just right for you. ”

Swimming through a long passage, there is a closed door in front, Shiso is opened with Zixia Ling, and then it is found that there is a swirling water seal setting inside, which can avoid a large amount of water rushing into the door, but in the process of opening and closing, there is still a lot of water entering the passage inside, but then there are several similar doors, and when they pass through these doors, there is a very dry corridor in front.

The road is twisted and turned, like a coiled long dragon, and when it comes to the end, there is a stone door with a lock hole in front, and after Shiso opened it with Zixia Ling, it was found that this was a marble paved corridor, only more than ten meters long, but there were nine doors, one in front and four on each side.

"Young master, I don't know which is the right door here. ”

"It's okay, the mechanisms are all closed, just try them one by one and you'll know, but I guess it's the one ahead!"

Yu Feng asked, "Brother Zisu, how are you so sure?"

Zi Su smiled: "I'm not sure, it's just a feeling, the person who can break through here should be very smart, but there is a saying that being smart is mistaken by being smart, because of the heavy mechanism in front, people can't help but guess that the door in front of them is problematic, so they will try to open other doors." ”

Shisu opened the door in front of him, and sure enough, the golden light was shining inside, and the gold chests were placed in the huge golden stone room, and on the middle wall of the stone wall were written the seven big characters of the treasure house of the purple mansion.

Yu Feng and Ziyun couldn't help but shout: "A lot of gold!"

Shisu and the second daughter counted carefully, there were more than 100 boxes of gold, according to 10,000 taels of gold in one box, there were 1 million taels of gold here

Prosperous collection, troubled gold.

If in troubled times, relying on this gold can quickly pull up a huge team to fight in all directions and compete for the world.

Zi Su collected fifty boxes of gold in the martial soul space, and he had to do a big career next, and the money was never too much, but the resources of the Zifu Treasury could not be taken up all at once, so he only took half of it.

Entering through another door of the vault, there was the Purple Mansion Silver Vault, which was filled with hundreds of chests of silver.

Shiso took a hundred chests of silver and entered the next portal.

Open the door, there are weapons everywhere, and there are eighteen kinds of weapons, even if it is a variety of Qimen weapons, there is no shortage, Yu Feng saw a pair of copper hammers, picked them up and tried them, and asked: "Do you think the copper hammer looks majestic or a bronze man?"

"Bronze Man. Shiso and Ziyun said in unison.

"Okay, then I won't change it. ”

Soon, in the new area of the armory, Shiso found the Zixia Sword, and when he held it in his hand, he had a very cordial feeling.

Zi Su knew that the Zixia Sword, like the Zixia Order, had the spiritual imprint left by its predecessors.
