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

The speed of Zhang Tie in the water is driven by the absorption channel opened in the water by the Black Iron Fort. After the water flow is sucked into the Black Iron Fort, the reactionary tension in the sea due to the vacuum effect is generated. This force comes from the Black Iron Fort , So it is completely controlled by Zhang Tie's mental power, which can be large or small.

A few years ago, when Zhang Tie first reached the Evandara Islands by sea, he was underwater, relying on the Black Iron Fortress and ocean currents to travel more than 10,000 kilometers in three days. At that time What restricted Zhang Tie was his body's ability to withstand the friction of water. Because of the friction and pressure of the water flow in the sea, Zhang Tie can even exercise while driving in the water to obtain iron fetuses.

This time, Zhang Tie became a knight, and the heart of the knight’s control over the absorption channel of the Black Iron Fort space was more flexible, and the body's endurance reached a terrifying level. Moreover, Zhang Tie also had a body of water blessing, and all his actions in the water It is unaffected, and there is a body of war energy, especially under the effect of advanced swift movement, his speed in the water completely exceeds the speed of his flight, reaching a limit that Zhang Tie could not imagine beforehand. .

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-protecting fighting spirit and physical 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 in the water reaches a certain level, as his body moves forward and the pressure in front of him and behind him is different, a large number of tiny bubbles that are even invisible to the naked eye are produced underwater. The resulting bubbles are on the frictional contact surface between his body and the water flow. At every moment, countless tiny bubbles are produced, and at the same moment, countless tiny bubbles burst. It is the burst of water bubbles. The huge impact on Zhang Tie.

At the moment that the bubble bursts, a huge instantaneous pressure impact and high-temperature micro-jet will be generated, which impacts Zhang Tie’s body like countless high-temperature water arrows and water hammers, corroding Zhang Tie’s body protection and fighting energy, and also brings high density. The frequent noise made Zhang Tie really feel what it's like to fly in the rain of bullets.

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

"Heller, what's going on, how come those terrible bubbles will be produced when my speed reaches a certain level in the sea, and those bubbles will have such a powerful destructive power?"

"This is because of the cavitation phenomenon and cavitation effect caused by the friction between the body of the Lord Lord and the sea water!" Heller answered Zhang Tie's question in simple language.

Cavitation phenomenon and cavitation effect? 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 drops to the saturated vapor pressure of the liquid, the formation, development and collapse of vapor or gas bubbles inside the liquid or on the liquid-solid interface is the process of cavitation. In the process of cavitation, cavitation bubbles are rapidly generated, expanded and collapsed, forming shock waves or high-speed micro-jets in the liquid, as well as heat release, noise and corrosion effects, which are cavitation erosion, which is also called cavitation erosion. Lord Fortress can observe the blades of the warship. The traces of corrosion damage on the blades of the old warship come from the cavitation and cavitation caused by the friction between the blades and the sea!"

The birth and death of the inconspicuous little bubbles in the water would actually produce violent shock waves, jets, high temperatures and corrosive effects. This surprised Zhang Tie. Isn't this the effect that the most powerful fighting spirit is investigating? If the knight's fighting spirit can have such an effect, wouldn't the power be increased tenfold.

While Zhang Tie was advancing rapidly in the water, he used his knight consciousness to feel and realize the process of the formation of tiny bubbles in the water.

At this moment, the maximum speed that Zhang Tie can reach underwater is almost three times that of his cruising speed in the air. He can travel at a speed of about 600 meters under water almost every second, and nearly 2,100 kilometers under water per hour.

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

The vast ocean is a great moat for others, but for Zhang Tie, it is simply a dream highway and super fast lane. He will consume fighting spirit to fly in the sky, but in the sea, he only needs to open the space of the Black Iron Fort. The siphon channel can be used, which is simple and easy.

With a sound of "pop," Zhang Tie flew out of the water on the sparkling sea and came to an altitude of more than 100 meters above the sea. He took out the compass in his hand and compared himself with the stars in the sky to confirm himself He then recalled the sea map of the Evandara Islands in his brain, and then flew to the southeast.

Zhang Tie's first goal was the Magic Snake Island.

The grudge between myself and Demon Snake Island a few years ago is now over.

When the scumbags on Demon Snake Island sent people to chase them down, I'm afraid they didn't think they would be able to come back so quickly.

Those people on Demon Snake Island were Zhang Tie’s important goals for returning to the ice and snow wasteland this time. To kill those guys, not only took revenge, breathed out a sigh, and did good deeds for the Ewendara Islands, but also gave himself fruit. Improve your own strength, and if you are lucky, you might be able to move those guys to the treasure house on the island. This is a good thing with multiple birds. Where can you find it?

Zhang Tie was flying high in the sky, and it was almost impossible for people on the sea to see it. As Zhang Tie flew, he changed his appearance to that of Peter Hampres again. Of course, Peter Hampres at this moment cannot be the same as five years ago. His appearance in the past five years seems to have not changed much, and if Peter Hampres’s appearance has not changed much compared to five years ago , Then, as soon as the Runner Ceremony of Huaiyuantang is finished, it is estimated that his identity will soon be worn out. Two such young and famous characters, and they are both knights, even if they are tens of thousands of miles apart, once someone compares themselves with Peter Hampres, everything will come out.

Fortunately, the incarnation of Peter was a white man. The white man has a strong body, but his face matures quickly. In the words of that guy from Tang De, he is crippled faster. The white man is sixteen or seventeen. When I was twenty-two years old, my face was very different.

"Heller, do me a favor. Show me what Peter should look like when he was 21 years old?" Zhang Tie wanted to get an impression first, and he would be better off.

"The period from the age of sixteen or seventeen to the age of twenty-two is the most important growth period in a person’s life, and it is also a stereotyped period. In terms of influence, the growth of the face during the five or six years may show vastly different changes. What do you want to change into?" Heller replied in the sea of ​​knowledge.

"Ah, is it so big?"

"Of course, if a young man goes from fifteen to sixteen years old and hits a plane to twenty-two years old, even if he is originally handsome, he will become insignificant, and an ordinary person, if he is fifteen or sixteen Always living in an environment of joy and health, life is full of sunshine, and can face all people and things with a tolerant attitude, that person will also become very handsome, flying a plane will make people ugly, and sunshine and tolerance Make people beautiful, what do you want to be?"

Hearing the word "flying" from Heller's mouth, Zhang Tie couldn't help but sweat. Thinking of Heller's ashamed and ugly beauty like the sun god, Zhang Tie's heart moved. After all, no one wants to be an ugly monster. Just try to change for the better. Just what I will be like in the past five years in the best environment, but don’t let those who have seen me fail to recognize me when they meet me again. !"

"No problem, your charm and basic face shape will not change. I promise that those who have seen you before will recognize you soon when they see you again!" Heller was silent for a moment, and then Asked a question, "Let me confirm again, do you want the best change that can happen to you?"

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

"Then you let go of your phantom bloodline, I will directly project the dynamic template into your phantom bloodline, so that you will automatically become that way, and the template will automatically follow the passage of time. Change in the best direction and you don’t have to worry about it..."

"Ok!"

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

Zhang Tie didn't know what he had become, but he knew that Heller would not pit him.

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

It was an island with an area of ​​more than 200 square kilometers. On this island, far away, Zhang Tie saw a volcano reflecting red light and spewing black smoke into the sky, the black smoke of the volcano. Most of the sky over the island is grayed out. In the sea near the island, there is also a large amount of magma gushing out. The water vapor from the submarine magma turns the sea around the island into a hot sea, often like being fogged. Shrouded in the same way, it is a bit like the sea of ​​fog that I submerged...
