"Director Li, your superpowers are forbidden, right? As long as you prohibit him from using superpowers first!"

\tLi Shibai had two superpowers a thousand years ago. But now Li Huo registered only one superpower, that is, "forbidden".

\tMeng Fei suspected that these abilities, like his system skills, were constantly upgraded and increased. Just like one bug triggered another bug. It’s just that Li Huo has not yet understood it.

\t "Good idea!"

\tWhen Li Huo expressed his opinion, An Xing's mouth was covered in blood and stammered and could not speak, with a look of despair on his face.

\t"It is forbidden to use the power to strengthen the body!"

\tWhen Ansheng's teeth were pulled out along with the red bloodshot and nerve fibers, Meng Fei could not "repair" him immediately.

\tBecause his "repair" is a process similar to time backtracking achieved using negative entropy. If "repair", it will cause the extracted teeth to return to their original position.

\t Fortunately, An Sheng is a executioner, and his body has a certain ability to recover, but it is slower than Meng Fei's "repair".\t

\t "Use your power, pinch this tooth with your fingers and rub it here, just like drilling a hole. Don't be too big."

\tTo be on the safe side, Meng Fei decided to try it from a small scale.

\t "Ph! No problem!"

\tAn Sheng spit out the blood foam in his mouth.

\tHis answer was a little vague. After all, his lips were swollen like a grilled sausage just now, but it was shrinking and recovering with the naked eye.

\tAn family's "reinforced steel and iron bones" started again, and Meng Fei felt that there seemed to be many invisible forces in the void squeezed over Ansheng as the center.

\t Under the squeeze, his two fingers became like iron pliers, clamping the teeth, like an invincible hardware processing robot.

\tThe tip of his hands scratched the surface of the pc glass quickly, which was many times better than Li Huo's operation, as if he was digging jelly with an ear-drawing spoon.

\tpc glass was visible to the naked eye.

\tBut they failed to penetrate the void outside the game plane or smell the fresh air outside. Instead, a very thin stream of water shot out!

\t "Damn it! It's water outside!"

\tAn Sheng had quick eyes and quick hands, and decisively blocked the leak with his fingers.

\t"To be precise, it's sea water."

\tLi Huo used his fingers to dip his finger on the back of Ansheng's hand, which was wet with water, and smelled it a little. He smelled a salty smell of the ocean.

\t "No wonder why it's so dark outside, because it's at the bottom of the sea!"

\tAn Sheng felt that his heart was swallowed by the dark seabed.

\tIf it is the seabed outside, how can you escape? Wouldn't opening the window mean drowning by the sea?

\t "It's not necessarily the seabed outside. Although it's very dark, even if it's shallow sea, if it's really past eight o'clock outside now, it's very dark underwater."

Li Huo said.

\t "You mean we just broke the jar and completely removed the window and swam out? What if it's deep outside? We don't have oxygen cylinders."

\tThis is diving with bare hands, without any equipment, diving directly, with a record of 113 meters in human history.

\tBut these are professional players. As ordinary people, it is best not to dive with bare hands more than 10 meters deep. Otherwise, it will easily turn into bare hands and seek death.

\tThe executioner An Sheng is strong and has the ability to recover, but he cannot produce oxygen even if he recovers. The lack of oxygen in his brain will cause him to fall into a coma, and his supernatural powers will also burp and turn aside. The same is true for Meng Fei.

\t "So, although we are in the sea, we are not necessarily deep seas. What we want to determine now is the depth of the ocean we are in."

Li Huo kept expressing very scientific insights.

\t "If the depth is less than 5 meters, maybe we can break the window and escape. If the depth is greater than 10 meters, in this situation where the direction of the sea is so dark that it is unclear, we have to reconsider it."

\t "It's a dark outside now, how do you know how deep we are here?"

Ansheng asked.

\t"This can be calculated."

\tLi Huo thought about it and said.

\t "Water pressure and depth have a certain relationship. As long as we know the water pressure, we can calculate the depth we are at."

\t "I've calculated it."

\tMeng Fei continued Li Huo's words.

\tHe lay on the ground and paid attention to the location of the water marks and turned on the micro-movement. After the micro-movement was turned on, he could accurately judge the position of the object and the calculation became extremely rapid.

\tIn less than a second, he had figured out everything he wanted. But it would be boring if he didn't slow down the time and talk about the actual process.

\tNo one except Aiting and Zhuque knew his micro-operation ability. So he still had to pretend to do some calculations and briefly describe it to the two present.

\tAs for whether they can understand it, it is not his business.

\tThis thread of water was extremely powerful, and it shot directly from the small room into the living room. Based on his "micro-working" gaze, the farthest reached the floor 6 meters away.

\tThis is the known condition. The solution target is now the depth of the water level where the hole is located.

\t According to the calculation formula of liquid pressure, the pressure f that can be generated by a small hole is the pressure * the cross-sectional area of ​​the small hole. Assuming that the cross-sectional area is s, and the water pressure at the water depth h is the density of water 1000* gravity acceleration g* the water depth h. Therefore:

\tf    =    1000   *       ghs, get equation (1).

\tSuppose the length of the small hole is dl, then the volume of water in the small hole is dl*s. And it is known that the density of water is 1000, then the mass m of water in the small hole is:

\tm    =    1000   *     dl   *     s.

\t According to the law of kinetic energy, the water in the small hole accelerates the distance of dl under the action of pressure f, and the kinetic energy obtained will be one-half times the mass times the square of the velocity v. The equation is as follows:

\tf*dl    =(1/2)*    m   *(v^2).

\tm has been determined to be 1000    *     dl   *     s, so the equation is:

f*dl    =(1/2)*    1000    *                                                                                                                                                                                                                                           �

Substitute equation (1) into equation (2) to get:

1000    *     ghs   *     dl    =(1/2)*    1000   *       *dl*(v^2)

Eliminate the 1000*     s   *                                                                                                                 �

v^2    =    2gh\t

In other words, the height h is directly related to the initial velocity of the ejected water. If the velocity v of the water flows out of the small hole is known, the depth of the water level where the small hole is located can be directly calculated:

h    =(v^2)/(2g)

Among them, g is gravity acceleration 9.8, so the only unknown amount that needs to be found is the initial velocity of the water flow v!

The water flow velocity is horizontal, and it will hit the ground after shooting 6 meters. The distance of air resistance loss is roughly estimated at 30%, and it can shoot 9 meters without resistance.

How long did this 9 meters distance take? Time is the time it takes for the water droplet to fall from a small hole to the floor. This is a free fall motion. How to solve it?

In free fall motion, height h is equal to half of gravity acceleration g multiplied by the square of time t. Therefore:

h    =(1/2)*    g   *(t^2)

It is known that h is the vertical height between the small hole and the floor. After Meng Fei's "micro-operation" visual measurement, it is about 1 meter, and the gravity acceleration is 9.8, so time t is:

(t^2)=    1   *  2/9.8

t is about the square root of 0.2, which is about 0.45 seconds.

The lateral velocity v of the water flow shot 9 meters away in 0.45 seconds, so this speed can be easily calculated!
