The three of Zi Su moved towards the center of the lake and continued to dive.

The diving limit of ordinary humans is more than one hundred meters, but the limit of warriors can reach two or three hundred meters.

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

However, humans are still not as good as marine species, such as sperm whales, which can penetrate more than 2,000 meters of sea areas.

When he dived about 150 meters, Zi Yun began to feel a little chest tightness. Zi Su used Xiaoyao Xuanshou to relieve her pressure. As for him and Yu Feng, he did not feel any discomfort.

Zi Yun pointed to a flat black and purple rock wall in the water and said, "Young Master, here is the place where you open and close the main gate of the mechanism. If you see it, there is a hole there. You can insert it into Zixia Order. Turning counterclockwise is to close the mechanism, and turning clockwise is to turn on the mechanism. Oh, by the way, when turning, you must inject Zixia true energy, otherwise it will be ineffective."

The rock wall of Perilla looks very smooth and can still be maintained in water for so many years, which means that the rock wall must have been coated with some special coating.

"Well, I understand." Zi Su took out the Zixia Order from the martial soul space and tried to insert it into the hole. But he found that there was a foreign object inside and it could not be inserted smoothly. He pulled out the Zixia Order and used the Dragon Blood Pulse Palm to suck all the foreign objects clean, and then inserted it again. He inserted it to the bottom. Zixia Order only left the handle outside. He held the handle and cast Zixia true qi to try to rotate counterclockwise. It was difficult to turn at the beginning, but it became easier after turning it away. When it turned to 360 degrees, there was only a click, as if there was a mechanism inside being locked, and then Zixia Order could not rotate.

"Okay, the main gate of the agency has been locked. Let's go down to find the entrance." Zi Su said, pulling out Zixia Order.

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

"I'll go in first, Yun'er follows, behind Fengfeng Palace." After Zi Su said that, she took the lead and entered the entrance of the cave.

Although the entrance of the cave was narrow, the passage inside the cave suddenly became clear and it became much bigger. Zi Su waited for a while and the two women also entered it.

The three of them swam together. As soon as they turned a corner, a strange noise suddenly came from the front, and the water also had a strong spiral. Zisu's perception was the most sensitive. He suddenly saw a green python in front of him, with feet as thick as thighs and more than ten meters long, swimming quickly towards the three of them.

Women are basically afraid of snakes. When Zi Yun saw it, she hurriedly hid behind Zi Su, but Yu Feng was an exception. She took out the bronze man and smashed it in a mess at the bloody mouth of the python. The python's teeth and mouth were smashed into pieces, causing it to roll violently. Zi Su took out the dragon sword, slashed across its abdomen, peeled it open, and then gently lifted the tip of the sword, and a crystal inner elixir was picked out. At this time, Yu Feng's bronze man hit the snake's head and smashed its head to pieces.

"Come on, Yun'er, swallowed this inner elixir."

"It's so disgusting if you don't swallow it."

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

Zi Yun approached and smelled it and found that there was indeed a strange fragrance. So she suppressed the disgusting feeling and swallowed the inner elixir of the python. Soon the inner elixir had an effect in her body. She found that her chest was no longer stuffy and her ears were no longer roaring.

"Yun'er, this inner alchemy has been around for at least a hundred years. As long as you absorb this power well, it is entirely possible to break through to the God of Martial Arts. Of course, the most important thing is to have corresponding spiritual improvements."

"Ah, this inner alchemy is so powerful. I would have been dissatisfied if I had known it. How good it would be for the young master to take it."

"Young master, even if I don't practice my skills, I'm growing very fast now. How can I take the inner alchemy?"

"That is, with Brother Zi Su's dragon blood spiral, the speed of absorbing the spiritual energy of heaven and earth is dozens of times that of ordinary warriors. Taking the inner alchemy is not very effective, and Zi Yun will just be able to subdue you."

Swimming through the long passage, there was a closed door in front. Zisu opened it with Zixia. Then I found that there was a circling water sealing setting inside, which could prevent a large amount of water from rushing into the door. However, during the opening and closing process, a lot of water still entered the inside passage, but then several similar doors were followed. When passing through these doors, there was a very dry corridor in front.

The corridor was winding, like a coiled dragon. When we reached the end, there was another stone door with a lock hole in front. After opening it with Zixia Order, Zisu found that it was a marble corridor, which was only more than ten meters long, but had nine doors, one in front and four on both sides.

"Young Master, I don't know which one is the right door here."

"It doesn't matter, the authorities have been closed. Just try them one by one, but I guess what's right in front of me!"

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

Zi Su smiled and said, "It's not certain, it's just a feeling that people who can break through here should be very smart, but there is a saying that being smart is just mistaken. It's because of the many mechanisms in front that people can't help but guess that there is something wrong with the door directly in front, so they will try to open other doors."

Zisu opened the door directly in front of him and was indeed right. The golden light shone inside, and golden boxes were placed in a magnificent stone chamber. On the middle wall of the stone wall, the seven big words "The Vault of the Zifu Treasure House" were written.

Yu Feng and Zi Yun couldn't help but shout, "So much gold!"

Zisu and the two girls counted it carefully and found that there were more than 100 boxes of gold. According to one box of gold, there were one million taels of gold here.

Collection in prosperous times, gold in troubled times.

If you are in troubled times, relying on these gold can quickly lead a huge team to fight all directions and compete for the world.

Zisu collected fifty boxes of gold in the martial soul space. He had to do something big next, and he would never have much money. However, the resources in the Zifu Treasure House could not be taken away at once, so he only took half of it.

Entering from another door in the vault is the Zifu Silver Deposit, where there are hundreds of boxes of silver in it.

Zisu took a hundred boxes of silver and entered the next portal.

When I opened the door, there were weapons everywhere, and there were all kinds of eighteen weapons. Even if there were various kinds of weapons in the Qimen, 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." Zi Su and Zi Yun spoke in unison.

"Okay, then I won't change it."

Soon, in the newly entered area of ​​the arsenal, Zi Su found the Zixia Sword and held it in his hand, and felt very friendly.
Chapter completed!
