Zhou Shen originally planned to go to the old monk, but he faintly felt that the [Iron Underwear] was about to be upgraded, so he went all the way to the sea.

After crossing the roadbed, they came to the rocky beach below, and then with a plow step, the man was ejected like a cannonball that burst out, and fell into the sea with a "poof".

Three days ago, he needed to bear weight in the sea to ensure that his body would not be washed away by the turbulence under the seabed, but after gaining insight into the mystery of the current of the sea, he could use the "whirlwind current" in the water to press his body down.

This is a little tricky to explain, the "whirlpool" is somewhat similar to a whirlpool, but it is not a whirlpool, but a positive and negative current produced by the sea water impacting each other.

There are a lot of whirlpools under the seabed, and ordinary people can't catch them at all, but his own physical strength and energy have reached a very high level, and the [Jumping Technique] has also reached the grandmaster level, so he can easily capture the whirlpool.

He only needs to use the whirlwind current to quickly sink his body to the bottom of the sea.

At the same time, when he wants to leave the bottom of the sea and go up, as long as he leaves the downward whirlpool and finds the floating whirlpool, he can help his body to float to the surface faster.

After sinking to the bottom of the sea, his super sharp body immediately caught the "offshore current" under the seabed, and he followed the offshore current under the seabed and quickly ran towards the depths of the sea.

Because these rip currents will help him "split" the resistance of the sea in front of him, he can run at least twice as fast as before.

In other words, he can run at an astonishing speed of more than 50 kilometers per hour under the seabed!

About half an hour later, he came to the Grand Canyon south of Tai Kok Tsui.

The depth of the rim of the canyon is only about 80 meters.

Zhou Shen came to the submarine canyon and followed the whirlpool.

90 meters.

120 meters.

150 meters.

200 m ......

The Garmin diving watch he bought for more than 10,000 yuan had long been scrapped, and he bought a "Breitling" professional-grade diving watch in Yangcheng, which can reach a maximum depth of 2,000 meters.

He stopped until he reached a depth of 247 meters.

This is an underwater platform, his alloy gun is embedded in the cliff wall, and there is a large black fish more than a meter on the tip of the tip, with a large head and a small tail, bulging eyes, and a mouth turned out, revealing hideous and terrifying teeth, which looks very similar to a tiger shark.

This big sea fish actually attacked him last night and was nailed to death by him with a single shot.

It's still the same as last night, first start practicing [Xingyi Fist] and [Spring Legs], then [Grabler], [Seven Star Fist], and [One Finger Zen].

There is no suppression of the weight-bearing suit, and at the same time, he does not run and land with the "downstream", "countercurrent", and "whirlwind current" on the bottom of the sea, but simply stands under the bottom of the sea to practice the exercises, and he needs to allocate a lot of energy to control his body, so as not to let his body sway from side to side with the undercurrent of the seabed.

However, this not only did not affect the cultivation effect, but it was of great help to improve the proficiency.

Because battles often break out suddenly, you can't expect to be in the ring, or on smooth and smooth roads, and maybe in the uneven Tanaka, or Inoue, Matsushita, Takeshita, Watanabe, and Yamaguchi.

The Seven Star Fist, which was stuck on the bottleneck, took the lead in breaking through, from the "consummation level" to the "master level".

followed by one-finger Zen, which also broke through from the consummation level to the "master level".

As various skills casually poured into his brain, his understanding of Seven Star Fist and One Finger Zen also rose to a new level.

The power has been greatly improved.

"Hey, two skills in a row have been upgraded to the master level, before the change, the stomach has already turned over the river and the sea, and the black hole vortex has even sucked up all the internal organs, but now I just feel a little hungry, why is this?"

"Could it be...... Just ate five catties of sea snake meat in the morning? Or has it broken through to the grandmaster level, and the body's ability to resist hunger has increased? ”

He couldn't help but wonder to himself.

After feeling some of the energy in his body being sucked away, his stomach quickly returned to calm.

Anyway, it's not a bad thing, he just didn't care.

Looking at the stats panel, the stamina and stamina have each increased by 0.2, becoming 25.1/24.6.

He can clearly feel that the strength of his body has increased a lot, the most obvious is to resist pressure, and he has reduced a lot, if he used to be carrying a 1,000-kilogram sandbag to practice his fists and feet, then now he feels that there are only 800 kilograms left.

However, when Yu Guang saw the remaining life, the joy in his heart immediately disappeared.

"70 years, 12 days ......"

Cultivating under the sea at a depth of 247 meters, his lifespan decreased very quickly.

In two hours, his lifespan changed from 70 years and 21 days to 70 years and 12 days, a total of 9 days, which is very terrifying.

You must know that in the past three days, his lifespan has increased by a total of 80 days, but his cultivation under the sea has decreased by 30 days, and the loss is large.

"After the longevity formula got stuck on the bottleneck, my lifespan grew less and less, and if I continued like this, I felt that my lifespan would soon enter a negative growth stage."

"No, we must break through the longevity formula as soon as possible and see how the next level goes? If it really doesn't work, then you have to change the exercise. ”

", why hasn't the iron underwear broken through, obviously I felt like I was about to break through yesterday, why didn't I break through today?"

Zhou Shen did not cultivate, but stood quietly under the water.

In the past, when I was practicing, my lifespan was reduced by 9 days in two hours, and the average was reduced by 13 minutes by one day, but after I stopped practicing, I only had to fight against the pressure of the seawater, and the load on my body was greatly reduced.

In addition, "physical strength" and "energy" have just increased by 0.2 each, so standing in the water for 29 minutes will reduce the life expectancy by one day.

Just as he was about to come back in the evening, suddenly, a large stream of information fragments flooded into his brain.

He opened the attribute panel and saw that the [Iron Underwear] had indeed been upgraded.

"Hahaha, it's finally upgraded......"

As soon as he was excited, a strong hunger rushed over him, although it was not as strong as the previous epiphany, but it also made him feel that all his internal organs were about to be devoured.

He was also prepared for this, walked to the deep-water waterproof bag next to it, opened it and took out only about a third of the fragrant wood balls left from it.

He has never been willing to eat this fragrant wood ball, just in case of emergency.

He was worried that the fragrant wood balls would melt when they encountered the seawater, so he stuffed the fragrant wood balls into his mouth along with the waterproof bag, and then ripped the waterproof bag from his mouth and swallowed it into his stomach along with the excess seawater.

Like eating the sea flower, he could clearly feel that the fragrant wood ball turned into a torrent of energy and flowed into his stomach.

The intense hunger in my stomach was quickly filled.

He looked at the level of the iron underwear, which had finally changed from "master" to "grandmaster", and couldn't help but be excited.

"I've been waiting for a long time, and finally today!"

And with the upgrade of the iron underwear, the physical strength and energy have each increased by 0.3 points, and the body is like a powerful force surging in the muscles.

But before he could feel it, the familiar feeling of discomfort came to him.

"Hiss...... Yes...... It's molting again......"

Zhou Shen was like a python, constantly twisting his body, and soon the skin on his body began to crack, he stretched out his hand and kept tearing, and the skin kept falling.

He took off all his clothes, pressed the stone against it, and then began to wash the molt on his body with the seawater.

At the same time, the nails and hair fell out one after another.

The tooth hadn't fallen out this time, but he felt it visibly stronger.

"The iron sheet can definitely be bitten off, I don't know if it can bite off the steel bar? After going back and waiting to go ashore, find a steel bar and try it. ”

He couldn't help but think excitedly in his mind, and then realized that something was wrong, "Wow, why do I feel that the pressure is suddenly gone?" At a depth of 247 meters, it seems that there is almost no pressure on me. ”

"It is estimated that in addition to the increase in physical strength and energy, it should be the reason for the grandmaster-level iron underwear!"

"Let me see where your limits are?"

Zhou Shen thought excitedly, and then came to the edge of the platform of the submarine canyon, felt the whirlwind flow, and his body fell down freely, while his arm kept grasping the canyon rock behind him.

250 meters.

260 meters.

280 meters.

300 meters.

350 meters.

400 meters.

It was almost pitch black under the seabed, and with Zhou Shen's super night vision, he could only see two or three meters in front of him.

"Can't go any further......"

When he reached 458 meters, the sixth sense told Zhou Shen that it would be very dangerous if he continued to dive.

Not only did the pressure of the sea water become extremely terrifying, making his body and internal organs feel extremely uncomfortable, but also the consumption of Qi at this depth was very large.

"It seems that 458 meters under the sea is the limit of what the grandmaster-level iron underwear can withstand!"

He was decisively ready to leave.

However, at this moment, he felt a hole in the cliff wall behind him with his right hand, "Hey, what is this?" ”

He turned around and saw that it was actually a cave with an oblique upward slope, and the diameter of the cave entrance was about one and a half meters.

The artist was bold, and Zhou Shen swam into the hole diagonally upward.

After swimming about twenty meters forward, his head suddenly popped out of the sea.

", it's actually a submarine cavity area."

ps: I went to watch the little wrecking ball 2 at night, and I came back a little late and started first.
