Zhang Tie once again broke through the limit of his speed in the water.

Zhang Tie's speed in the water comes from the absorption channel opened up by the Black Iron Fort in the water, and the water flow is sucked into the water after the Black Iron Fort because of the reaction force generated by the vacuum effect.

A few years ago, when Zhang Tie first reached the Ewendala Islands by sea through Guò, he traveled more than 10,000 kilometers in three days under water, relying on the Black Iron Fort and the ocean current. Because of the friction and pressure of the current in the seawater, Zhang Tie can even exercise while traveling in the water to obtain the iron fetus fruit.

This time, Zhang Tie became a knight, and the heart of the knight was more flexible in controlling the spatial absorption channel of the Black Iron Castle, and the body's bearing capacity reached a terrifying level, and Zhang Tie also had the body of Shui You, and his actions in the water were not affected, and he had the battle qi to protect his body, especially under the blessing of the effect of the advanced speed technique, his speed in the water completely exceeded the speed of his flight, reaching a limit that Zhang Tie could not imagine in advance.

This limit is also the maximum speed that Zhang Tie's body can withstand in the water at the moment. When this speed was reached, Zhang Tie's body protection battle qi and body endurance encountered unprecedented challenges and pressures that Zhang Tie had never imagined.

This challenge and pressure came from something that Zhang Tie had never cared about—the tiny bubbles in the water.

When Zhang Tie's speed reaches a certain level in the water, the underwater pressure in front of and behind him is different as his body advances. The large number of tiny bubbles, some of which are not even visible to the naked eye, were created under the water, and the bubbles produced were on the frictional contact surface of his body with the current. Every moment, there are countless tiny bubbles, and at the same moment, there are countless tiny bubbles bursting, and it is the bursting of the bubbles in the water that brings a huge impact to Zhang Tie.

At the moment when the bubble bursts, there will be a huge instantaneous pressure shock and a high-temperature micro-jet. Like countless high-temperature water arrows and water hammers, it impacted Zhang Tie's body, corroded Zhang Tie's protective battle qi, and also brought dense and high-frequency noise. made Zhang Tie really feel what it was like to fly in a rain of bullets.

After doing this several times, Zhang Tie found that as long as his speed in the water reached a certain distance, such a strange phenomenon would occur, and he couldn't help but ask Heller.

"Heller, what's going on. How is it that when my speed reaches a certain level in the seawater, I produce those horrible bubbles. And those bubbles will be so destructive? ”

"This is because of the cavitation phenomenon and cavitation effect caused by the friction between the castle lord's body and the seawater!" Heller answered Zhang Tie's question in succinct language.

Cavitation and cavitation? Zhang Tie was even more confused, these were two words he had never heard of.

"This is a physical phenomenon, when the local pressure in the liquid is reduced to the saturated vapor pressure of the liquid, the process of formation, development and collapse of vapor or gas cavitation that appears inside the liquid or at the interface between liquid and solid is the cavitation phenomenon, and in the cavitation process, the vacuoles are rapidly generated, expanded and collapsed, forming shock waves or high-speed microjets in the liquid. There are also exothermic, noise and corrosive effects. It is cavitation, and cavitation is also known as cavitation! The lord of the castle can observe the paddles of the ship, and the traces of corrosion and damage on the paddles of the old ships come from the cavitation phenomenon and cavitation erosion caused by the friction between the paddles and the seawater! ”

The birth and death of the inconspicuous little bubbles in the water actually produced violent shock waves, jets, high temperatures and corrosive effects, which surprised Zhang Tie, isn't this the effect of the most powerful battle qi being pursued? If the knight's battle qi could have such an effect, wouldn't it be ten times more powerful.

Zhang Tie was advancing rapidly in the water, and at the same time, he used his knightly consciousness to feel and comprehend the process of the formation of those tiny cavitations in the water.

At this moment, the maximum speed that Zhang Tie can achieve underwater is almost three times his cruising speed in the air, and he can fly underwater about 600 meters per second and almost 2,100 kilometers underwater per hour.

It took him three days to reach the Ewindara Islands from the waters near Huaiyuan County, but this time, it only took him about five hours to reach the waters of the Ewendala Islands.

The vast ocean is a moat for others, but for Zhang Tie, it is simply a dream highway and super fast lane, he has to consume war qi when flying in the sky, but in the sea, he only needs to open the space siphon channel of the Black Iron Castle, which is simple and trouble-free.

With a "bang", on the sparkling sea, Zhang Tie flew out of the sea, came to the sea at a height of more than 100 meters, took out the compass in his hand, compared it with the stars in the sky, determined his position, and then recalled the sea map of the Ewendala Islands in his brain, and then flew to the southeast.

Zhang Tie's first target was Demon Snake Island.

The feud between himself and Demon Snake Island a few years ago is now time to end.

When those miscellaneous pieces on Demon Snake Island sent people to hunt down and kill them, I am afraid they didn't think that they would be able to kill them so quickly.

Those people on the Demon Snake Island are Zhang Tie's important targets for returning to the Ice and Snow Wasteland this time, killing those guys, not only taking revenge, but also doing good things for the Ewendala Islands, and eating fruits for themselves, improving their strength, if they are lucky, they may be able to move those guys' treasure troves on the island, so where to find such a good thing in one fell swoop.

Zhang Tie flew very high in the sky, and it was basically impossible for people on the sea to see it. What Hamples looks like. Of course, at the moment Peter. Hamples, definitely not like five years ago, his appearance in the past five years seems to have not changed much, and if Peter. Hamples' appearance has not changed much compared to five years ago, so as long as Huaiyuantang's wheel ceremony is completed, his identity is estimated to be worn soon. Two people who are so young and so famous, and both are knights, even if they are tens of thousands of miles apart, once someone puts them and Peter. As soon as Hampres compared, everything came out.

Fortunately, Peter, who was incarnated at the beginning, was a Caucasian, and the Caucasian was strong, but his face matured quickly, in the words of the poisonous tongue of the guy Donde, it was crippled relatively quickly, and the difference between the face of the Caucasian when he was sixteen or seventeen years old and when he was twenty-one or twelve years old was very big.

"Heller, do me a favor and show me what that Peter should look like when he's twenty-one?" Zhang Tie wants to have an impression first, and he is better to change.

"The period from the age of sixteen or seventeen to the age of twenty-one or twelve is the most important growth period in a person's life, and it is also the stereotyped period, during this period, a person's appearance will be affected by the environment, mind, living habits and other aspects, and the growth of the face may show a very different change in the past five or six years, what do you want to change?" Heller replied in the midst of the sea.

"Ah, is it that big?"

"Of course, if a young person jerks off from the age of fifteen or sixteen to the age of twenty-one or twelve, even if he is originally handsome, he will become obscene, and a person with an ordinary face, if he has been living in a happy and healthy environment since he was fifteen or sixteen years old, his life is full of sunshine, and he can face people and things with a tolerant attitude, that person will also become very handsome, jerking off will make people ugly, and sunshine and tolerance will make people beautiful, what do you want to become?"

Hearing the word jerking off from Heller's mouth, Zhang Tie couldn't help sweating, thinking of Heller's handsome and beautiful appearance like the sun god, Zhang Tie's heart moved, after all, no one wants to be an ugly monster, "Then try to change to the good side, just when I am in the best environment, what will become in the past five years, but don't let those who have seen me not recognize me when they see me again!" ”

"No problem, your verve and basic face shape won't change, and I promise that those who have seen you before will quickly recognize you when they see you again!" Heller was silent for a moment, then asked another question, "Let me make sure, are you the kind of best change you want to happen to you?" ”

"Yes, the best!" Zhang Tie confirmed......

"Then you let go and open your phantom bloodline, I will directly project that dynamic template into your phantom bloodline, so that you will automatically become like that, and in the future, that template will automatically change in the best direction according to the passage of time, you don't have to worry about it......"

"Okay!"

Zhang Tie opened his spiritual power and phantom bloodline, and felt that Heller had projected a template for himself, and then his appearance and body shape began to undergo some subtle changes, and the phantom bloodline was activated and began to change automatically.

Zhang Tie didn't know what he had become, but he knew that Heller wouldn't cheat him.

After just over an hour of flying, in front of Zhang Tie's eyes, an island appeared on the sea level in the distance.

It is an island with an area of more than 200 square kilometers, on this island, from a distance, Zhang Tie saw a volcano that reflects red light and spews black smoke into the sky, the black smoke of the volcano makes most of the sky of the entire island gray, and on the sea surface near the island, there is also a large amount of magma gushing out, and the water vapor evaporated by the magma on the bottom of the sea makes the sea around the island become a hot sea, often as if shrouded in fog, it is a bit like a sea of fog that he cultivates......
