Everyday heroes

Chapter 321 Destroyed
Other ideas cannot be verified due to immature conditions around or lack of props.

However, the attempt of water knife technique can still be pondered.

Guan Lang returned to the apartment and persuaded his cousin who was going to school with an umbrella.

It was raining so hard that I would probably get drenched before I got to school under an umbrella and in the rain.

Sent her downstairs and hailed a taxi.

After seeing off his little cousin, he went back upstairs to inquire about the principle of the industrial water jet.

He originally thought that the water jet would only work if the water pressure was high enough, but after checking, he found out that the water had to be mixed with abrasives such as pomegranate sand and carborundum to assist in cutting.

The principle of this high-pressure water jet cutting technology is to let ordinary water pass through an ultra-high-pressure pump, and then pressurize the water to 0.1 MPa. In order to maintain the stability of the high-pressure water flow, it is necessary to stabilize the pressure through an accumulator, and finally Passing through a very small nozzle with a diameter of about 0.2-[-]mm, a unparalleled water arrow at a kilometer per second can be ejected.

After reading the principle, he knew that he might be thinking too much.

It is obviously difficult for him to achieve a series of processes of industrial water jets through Tai Chi.

The minimum accuracy cannot be satisfied. His current accuracy is about 1mm, which is far from the required caliber.

And the conditions for making ultra-high water pressure are not satisfied either.

Taking the surface area of ​​a water droplet as 1 square millimeter as an example, in order to create a pressure of 0.1 MPa, it is necessary to apply a force of [-]kg in the tiny area of ​​this square millimeter, and a force of about [-] kilograms is required for a pressure of [-] megapascals.

The maximum strength of his Tai Chi is about 110 catties, which is quite satisfactory.

But he was completely unable to apply evenly concentrated strength to such a small area at the same time.

The difficulty is too high, and it feels that it is not the fairy operation that he can achieve at this stage.

The area of ​​one square millimeter is too small, and the nail cap of the index finger is almost a hundred times the area.

His manipulation accuracy of Tai Chi Force can be maintained at about one millimeter, but it doesn't mean that he can concentrate all his strength within such a small range.

Although the imagination is beautiful, the reality is cruel.

The water flow of one kilometer per second is really pumping water and breaking the knife. The small white line with three times the speed of sound can cut almost all materials at super speed, such as glass, steel, stone, reinforced concrete, titanium, chrome and various composite materials, and only like diamond Materials such as ultra-high hardness can stand out.

He tried it in his bathroom.

First, use part of the force to wrap a ball of water in the air, and then simulate a pipeline environment to transport water flow, and gather most of the force at the end to squeeze the water droplets as much as possible to form water pressure.

It turned out that it really couldn't be realized, and it can only be used for performance at this stage.

There are several problems.

First, the pressure is not concentrated enough, and the fastest initial velocity of the water droplets ejected is only 40 meters per second, which is very different from the water jet of kilometers per second.

The speed of the water droplets weakened quickly after being ejected, and the water pressure transformed by his Tai Chi power was extremely unstable, which also caused the water flow he pressed to be intermittent, unable to form a high-speed moving water column.

Maybe it will be possible in the future, but in his current situation it is still too reluctant.

More stable control, mental power and stronger Tai Chi power are needed.

Guan Lang finished exploring new moves.

It’s not that there is no gain. Maybe when the spiritual force is raised to a higher level or the acquired internal force is purified into innate qi, there will be a revolutionary improvement in Taiji force. At that time, there will be a realistic basis for the realization of ultra-high pressure water jets.

Guan Lang continued to take online classes as usual.

He has almost finished the advanced courses he bought.

In addition to the lack of practical work experience, he felt that he was already qualified for the job of teaching others.

The rain outside the window is still increasing.

He walked to the bare balcony and looked at a sky and rain that was as black as ink.

It was clearly noon, but it seemed like night.

It has been raining for several hours, isn't it raining?

It won't be waterlogged, will it?
Guan Lang was a little worried about whether the backward drainage system in the nearby old town could hold up.

It should be the biggest rainstorm today or even in recent years, right?
Guan Lang glanced at the ground of the community downstairs, and the road had turned into a raging river.

Various bits and pieces of garbage such as beverage bottles, leaflet paper, and clothes float on the water.

On the main road in the distance, cars are rushing through the "river".

His eyes turned to the distance, which was the direction of the yard.

It seems that his little eggplant, little tomato, and little Xi'an are in danger.

such a heavy rain.

Are you going to take Wu Yazhen home?

Guan Lang turned on the phone.

Wu Yazhen has already sent a WeChat message.

She told him not to worry, she suspended classes today, but she must stay in the school classroom now, the school considered the safety of the students, and informed the students to wait in the classroom until the rain subsided before leaving.

However, if the parents of the students arrive at the school and want to pick them up, the teacher will also let the students go, and if they want to go home alone, they can't.

Guan Lang asked if he wanted to pick him up and take him home.

But the little cousin doesn't seem to have this need.

On the contrary, there is still some peace and contentment.

Because of the weather, it is much more convenient to be able to ask the teacher anytime during self-study at school.

The other students were chatting, playing with mobile phones, or waiting for their parents to pick them up, but no one came to grab her individual tutoring time.

Guan Lang could do it after thinking about it, so he replied with a reply asking him to send it to WeChat at any time.

With such turbulent surface water, it is not safe to travel.

The main reason is that I don't know what kind of garbage is mixed in the water. If sharp metal fragments or glass slag cut the legs and feet, and then soak in the muddy and dirty water, it may be infected with germs.

He is not afraid of rough skin and thick flesh, but Wu Yazhen's thin skin and tender flesh are still somewhat risky.

On Douyin, videos of various rainstorms in the circle of friends have been circulated wildly.

Tiannan is like turning into Venice Water City.

There are also many people who used various large bathtubs as boats to shoot videos, and some people caught fish in the road water with fishing rods. This is obviously a natural disaster, but there are always people who are lively on the Internet.

After another two or three hours, he saw that the rain was still steady.

Although he didn't receive Wu Yazhen's WeChat message, he thought that something was wrong with the rain, and he thought it better to bring her back sooner.

Although staying in the school, the school should also properly arrange the safety of the students, but it is better to go home.

And there should be few places safer than staying by his side, right?
After sending a WeChat to discuss with Wu Yazhen, he took out the rain boots and rain pants from the warehouse, and hurried out with the rain gear.
