Chapter 3403

After chatting with director Gordon, a policeman ran over and said a few words in his ear before he smoked a few cigarettes. Gordon should have a click in his heart, changed his expression, apologized and hurried away.

Maybe the police officers found Dr. Santo's identity. Maybe the doctor had a driver's license in his wallet? Or maybe someone recognized his shoes?

It doesn't matter. Su Ming's goal of returning the body has been achieved. Everything subsequent has nothing to do with him.

"What do you find?" he walked in the rain with a cigarette in his mouth, came to Lorna's side and leaned against the car wreckage: "it's better to find someone along the magnetic field. It doesn't matter if I can't find someone. I have a backup plan. Don't put too much pressure on myself."

"Yes, it's at the south pole, the man we're looking for." Lorna pulled out her hand soaked in liquid metal and shook it. She straightened up and answered.

The girl looks in good shape. She also talks about inversion.

As like as two peas, she looks too thin and chin sharp, but she has a special "fan", who is exactly like the king of magneto.

"Sure enough, did you still use the earth's magnetic field? The strength of the other party's magnetic field is not high, so you suppressed it."

Kate's face is paler than Lorna's, perhaps because of her red hair. She looks like a dark beauty like a vampire. At this time, she touches her chin and makes tentative guesses, waiting for the capable person to give a definite answer.

The earth's magnetic field, in short, is dipole, which is similar to putting a magnet rod in the center of the earth and passing out near the north and south poles.

The magnetic poles do not completely coincide with the geographical poles, and there is a magnetic declination. Of course, the center of the earth is in a high temperature state, and there is no magnet rod. Instead, the magnetic field is generated by the current effect of the electrons in the outer core rotating with the earth.

In addition, the intensity of the geomagnetic field is very weak, which is another characteristic of the geomagnetic field. At the strongest poles, its intensity is less than 10-4 (T), and the average intensity is about 0.6x10-4 (T), which changes less with place or time, so it is commonly used（ γ)， That is, 10-9 (T) is used as the unit of magnetic field strength.

At this time, Batwoman also understood why the girl sought by the knell was called Polaris.

Because in ancient times, people didn't realize that the earth was a sphere, they began to use the magnetic field to guide the direction, but they didn't understand the specific principle.

Perhaps a student asked the teacher, "why does the North compass always point to the north?"

Ancient Chinese teachers couldn't tell why. They were so anxious that they scratched their ears and cheeks, but if they couldn't tell a principle, how would students teach their students in the future? Wouldn't this knowledge be passed on?

Sometimes application is more important than understanding. It is a human tradition to use skills that do not understand the principle. Don't expect primitive people to understand the principle of drilling wood to make fire.

Skills are useful and props are useful. Use them first. Studying principles will be a matter of the future.

Maybe the teacher was so worried that he couldn't sleep all night. As a result, he looked up and saw the stars, which gave him inspiration.

Polaris is very close to the north extension of the earth's axis, so people can always see it when they look at the sky at night, so the teacher has the answer and calls the students to point to the sky.

"The magnetic force is brought by Polaris."

Whether there is such a pair of teachers and disciples is unknown, but the saying that Polaris is the source of magnetic force is widely spread.

Today, with the development of science and technology, Polaris is still regarded as one of the sources of magnetic field in mystics. It is often used by fake dealers as an excuse to sell their crystals that can "regulate the human magnetic field".

"I don't care whether he is strong or weak. As long as he is an enemy, kill him." Polaris showed a lovely smile. Her style is very pragmatic.

"Slade, what do you say?" facing the heavy rain, the orangutan looked up at the man in meditation.

Su Ming picked him up, pinched the cigarette end in his mouth and put it away: "adjutant, send us to the South Pole."

..............................

"Are you sure it's right for us to leave the justice hall and investigate?"

Somewhere in the streets of Washington, D.C., green arrows and black canaries are hiding in the darkness before dawn. She seems to be afraid of the dark and clings to her ex husband's arm.

Women only affect the speed of archery. It's definitely a mistake to hold an archer's arm, but Oliver not only doesn't worry, but also has a dark and cool expression and enjoys the warm friction of his ex-wife.

"The enemy's attack on the justice alliance shows that it is aimed at some of us. Remember that someone pretended to be the death knell. The second round was those liquid metal robots."

He wiped his moustache with his empty hand and squinted at the chaotic street. At this time, they hid behind a dustbin and watched a single silver machine patrolling the street in the distance.

"So we're bait?" the Black Canary tilted her mouth. She obviously didn't like to be bait.

"Be happy, honey. At least we have Superman to support us."

Oliver pulled his head back from the top of the dustbin, leaned his back against the smelly wall, smiled at his ex-wife and said his dark plan:

"We want to liberate Washington DC and let those politicians have a way to mobilize the army and share the pressure for everyone in the justice alliance. This is not a superhero, but the difficulty of all mankind. After the babatos incident, I increasingly realize that more people is strength."

To put it bluntly, I want the government to send troops as cannon fodder. To put it better, it is "sharing the pressure".

The Canary looked at him with empty eyes and pursed her red lips: "that's why you took the young Titan team to hide in the Gotham sewer for a month? Even if there are no enemies on the ground, you still fight with the air?"

"That's not my caution. I really thought that I and those children were the last hope of mankind. If there was a mistake, how should I explain to the sacrificial people?" Oliver shook his arm, shook off the woman's hand, took off the bow and arrow on his back, and took out a special arrow.

It was a boxing glove fixed on the tip of an arrow. The glove was still green and looked like some kind of funny prop.

"Then you must be very happy at that time? You think I'm dead, so you can find a younger girl, right?" Dana's eyes suddenly became sharp, and she seemed to see through Oliver: "do you really take huimeizi as your sister? But how do I feel that she doesn't treat you as a brother? Speaking of it, she used to want to kill me..."

"That was all many years ago, and that was instructed by her mother. There was no need to turn over the previous things." Oliver stretched his bow and arrow and took a deep breath: "are you ready? I'll lead them over and see your soprano next."

"Hum, we almost died together in the command room. I don't want to die confused. Can I ask? Forget it, let's start, scum man." the black canary was ready for battle, but she didn't let go of her ex husband at all. She just hinted that she wanted some sweet comfort.

After the death knell saved them both, the family left, little Superman stayed, and things changed.

Oliver began all kinds of busy work, assigning tasks to some coming superheroes, arranging meals and rest for the survivors, finding a place to store the dead, and studying the bodies of those liquid robots.

Until she left the hall of justice, she didn't talk to her much. She felt like a redundant, or a follower who couldn't get in touch.

"How can I be a scum man?" Oliver shook his head and rolled his eyes. "Don't be unreasonable. If you don't concentrate on fighting, you'll only kill us both. I haven't lived enough."

"You..." Dana's face was so angry that she couldn't speak!

Every once in a while, the two people always quarrel for various reasons and shoot their feelings that were a little complex at once. This is probably a sadistic love with deep hatred.
