The waves on the sea came first, and the front of the building pointed to Gu Xue piled up.

From now on, the king must be on the tide, and he will see the silver mountain twenty times.

The cross wind and rain enter the building obliquely, and the spectacular should be praised.

The rain is over the tide and the river is blue, and the electric light is the purple snake.

A month has passed in the blink of an eye, and at this time, Lu Yuan has come from Xishu to a small island by the East China Sea.

The island was originally home to more than a dozen fishermen, but with the development of the economy, the islanders also yearn for a better life.

The islanders had gradually moved away from the island for the mainland a few years ago, with the only occasional fishing boat coming here to escape the storm.

However, this island is now suitable for Lu Yuan, two months ago, after Lu Yuan subdued Xiao Ding, he finally knew that the black energy he absorbed and refined was actually the water aura in the Five Elements Aura that the ancient qi practitioners said.

After leaving Xiaoding, Lu Yuan found that the aura on the earth today is too rare.

He couldn't absorb ten traces of water aura for a whole day of cultivation, and his cultivation speed became extremely slow.

In desperation, Lu Yuan thought that there was more water on the seaside, and maybe there should be more water aura by the sea.

So after some preparation, I came to this deserted island by the East China Sea.

After some bargaining, he rented a small house on the island, because it had been uninhabited for a long time, and the house was already overgrown with various plants.

This situation must be unacceptable to ordinary people, but it couldn't be better for Lu Tian.

After spending a whole day cleaning, Lu Yuan could finally cultivate happily.

Because the island has not been inhabited for a long time, the aura on the island is indeed much more than that of other places, and Lu Yuan carefully calculated that he could absorb about 30 threads of aura in a day of cultivation on the island.

This is already three times the cultivation in the mainland, Lu Yuan was overjoyed at first, but soon he frowned again.

Although the speed of cultivation on the island is much faster than in the mainland, even if you continue to cultivate at this speed, it will take at least three years to break through to the second level of qi training, and it will take at least 78 years to build a foundation and become a real qi practitioner.

Lu Yuan felt a burst of frustration at the thought that it would take 78 years to become a true qi practitioner.

There is no way to increase a person's lifespan during the Qi refining period, and he is not too young now, and he will almost die after 78 years!

"Looks like we'll have to find something else!"

"Since there will be more aura on the shore of the East China Sea, can the cultivation speed in the sea be faster!"

Thinking of this, Lu Yuan couldn't sit still, he immediately went to the beach, and when he arrived at the beach, he didn't hesitate at all, and jumped directly into the sea.

After carefully feeling the aura content in the sea, Lu Tian was pleased to find that his guess was correct, the aura content in the seawater was indeed higher than that on the island, and the deeper the distance from the sea, the higher the aura content.

If you can stay in the water for a long time to cultivate, then the speed of cultivation will definitely be faster.

At this time, a smile appeared on Lu Tian's face, it turned out that when he subdued Xiao Ding, Lu Yuan also obtained a spell secret book called "Five Elements Escape Technique" in Ding.

This escape technique is said to be one, but it can actually be regarded as five kinds of spells, but Lu Yuan only has water aura now, so he can only practice the "Water Escape Technique" in it for the time being.

Although he could only practice the "Water Escape Technique", it was enough for Lu Yuan, and as soon as he heard the name, he knew that he was a spell that used water to move forward and escape quickly.

But in addition to this, it also has a use of separating water, so that people can stay in the water for a long time.

This function is perfect for Lu Yuan.

Half a year later, Lu Yuan's "Water Escape Technique" was finally cultivated.

On this day, Lu Yuan stood on a reef and took a deep breath.

Then he turned on the "Water Escape Technique" and jumped into the sea.

At first, he only swam in the water not far from the surface, but he quickly adapted to the underwater environment.

He began to dive slowly, 50 meters, 60 meters, 70 meters, and 100 meters until he felt a little bit of water pressure.

In order to test the extreme depth of his diving, Lu Yuan continued to dive underwater, and when he reached two hundred meters, Lu Yuan had already felt the squeeze of the sea water on his body.

It seemed that this depth was the most suitable depth for his cultivation, he stopped and tried to cultivate, only to be pleasantly surprised to find that his cultivation speed at two hundred meters underwater was already 50% faster than on the surface of the sea.

If you have been cultivating two hundred meters underwater, it will only take two years for you to break through to the second level of Qi training.

Lu Yuan temporarily stopped his cultivation and continued to dive to the bottom of the sea, until he was three hundred meters down, and he was forced to stop.

Because by this time he already had a feeling that he was about to suffocate.

"It seems that my limit now is 300 meters!"

After Lu Yuan realized that he could no longer continue to dive, he immediately turned around and swam to the surface.

When he returned to the surface, he found that he was very far away from the island.

Looking at the direction of the island, Lu Yuan smiled, "Just in time to try the speed of the Water Escape Technique!"

He used the water escape technique with all his might, and after about 20 minutes, he returned to the island.

He estimated that he had just run almost 18 kilometers, that is, a speed of 54 kilometers per hour, which translates to a speed of about 29 knots.

Lu Yuan is staggered, he is only now just getting started with the "Water Escape Technique" and can run at this speed, and he doesn't know how fast he can run when the "Water Escape Technique" is completed.

Next, Lu Yuan tested in the sea at different depths, and finally found that he was the fastest at a depth of 20-50 meters above the water, about 30 knots.

The further down the speed will be slower and slower. When the water depth is 200 meters, its speed is only about 20 knots, and when it reaches 300 meters, it is not fast, and it is about the same as ordinary fish.

But this has made him very satisfied.

When he returned to his residence in the evening, Lu Yuan also checked on the Internet, and now the conventional submarines of various countries around the world have a diving depth of more than 300 meters, and the underwater speed is generally 15-20 knots.

In this way, Lu Yuan felt very incredible, he could actually compare the diving depth with conventional submarines, and the speed still had a certain advantage.

After the "Water Escape Technique" became small, Lu Yuan felt like a fish in the sea, so comfortable and free in the water.

On this day, Lu Yuan cultivated at the bottom of the sea as usual, and only returned to the hut on the island at night.

He took out his mobile phone on the table, and suddenly found that there were more than ten missed calls on the phone, and all of them were from his mother.

At this time, a wave of uneasiness rose in his heart.....
