Chapter 50: thunderstorm

"Dangdang, Dangdang."
The sound of friction between train wheels and rails echoed in my ears.
Baili Qingfeng sat on the train with his eyes closed.
The train runs twenty-four hours. He bought a ticket at 2:30 in the morning, and it took ten and a half hours to reach 400 miles from Mirow City.
There are too many stops on the train at this time, which seriously affects the speed of the train.
Baili Qingfeng maintained this squinting state, and time unknowingly dawned the next day.
At this time, there seemed to be a change in the train.
Baili Qingfeng opened his eyes and found that many people in the car were looking outside.
Baili Qingfeng glanced at it, and by the morning dawn rising from the sky, he found that on a road parallel to the railroad tracks, personnel carriers, armored vehicles, and tanks were lining up in a long line on the road. Depending on the scale, there is definitely more than just A regiment.
However, personnel carriers, armored vehicles, and tanks are not the key points. The key point is ...
The breath of smoke.
In these vehicles, Baili Qingfeng saw the smoke of smoke.
The army seemed to have just come down from the battlefield. Baili Qingfeng's eyes were sharp and he could see the wounded with bandages and blood.
A soldier sitting silently in the car, silently facing the train personnel, numb, silent, and for a moment, as the train tracks and highways separated from parallel to road, gradually drifted away, until completely invisible , Disappeared.
"Are you fighting? The Aurora came over?"
"No, we are south, the Aurora Empire is north, and we are not fighting against the people of the Aurora Empire."
"The size of the troops dispatched this time is not small. I just saw thousands of people, two or three regiments. We should know that we are fighting."
"I heard that there was a large-scale subsidence over Li Ke County a month ago. There are suspects of burrow people ... It is not far from Li Ke County. Is it a burrow people?"
In the car, many people talked, even if some people who had closed their eyes and consciously awakened at this time.
Baili Qingfeng listened, looked at the convoy outside the window, and was silent.
The warriors of the Jiang family, Eddie and Tiejianmen were unscrupulous, and large-scale soldiers are marching right now.
"I may have to change my understanding of the world ... this world is far less peaceful than I thought."
...
The train arrives in Miro at 2pm and is one hour late.
Compared to Charya's clear air, the city of Miro is raining.
Thunder showers.
It seems to herald something.
Baili Qingfeng got out of the car and was afraid to eat near the train station.
It's not a small possibility to eat a hundred yuan egg fried rice here.
He took a bus to a place one kilometer away from Tiejianmen, ate Chinese food, watched the rain outside, and made an advance of five yuan from the 200,000 destroyer funds collected, bought an umbrella, and propped up to Tiejian The door went.
The Iron Sword Gate was not built in the wild mountains and wild mountains of Osawa, and like the Jiang Family Wu Guan, the Iron Sword Gate also acts as a Wu Guan to survive in Miro City.
It's just that, compared to the Jiang Family Museum, the Iron Sword Gate covers a much larger area. There are not only three small buildings, but also two large basketball courts, as well as some equipment for exercise and activities.
When Baili Qingfeng came to Tiejianmen, he found that the atmosphere of Tiejianmen was a little tense.
The door was half-hidden, and there were two men who looked rather sturdy under the eaves.
When Baili Qingfeng came, he was seeing a car stopping at the gate of Tiejianmen. Two savage men stepped down from the car, and one of them also greeted him with an umbrella: "Liu Brother Twelve brothers, you are here, and now all but nine brothers have arrived. "
"What happened? How did Lu Shao's head call us all over?"
"Isn't the head of the team leading the door to Xia Ya yesterday? I started to contact this morning, and there was a call over Green Water Villa at more than nine o'clock."
"What happened? What happened !?"
"Go in again!"
The party quickly entered the yard.
"One more hasn't come."
Baili Qingfeng thought for a while, or planned to wait for someone to come together before starting, so as not to miss the net.
But just waiting and waiting was boring.
"It's not too rainy."
Baili Qingfeng looked up and looked at the cloudy clouds above his head, and the electric light shining from time to time in the clouds.
Cultivating thunder dominates the idea, making him extremely sensitive to external potential.
"The current electric field is 3 × 103N / C. If I stand still, it will definitely make people in Tiejianmen doubt. Then, in order not to frighten the snake, find something to do. . "
Baili Qingfeng picked up a small stone, came to the wall, and calculated the wall as a blackboard.
Think of a cloud as an infinite plane. There is a negative charge on the ground. The magnitude of the electric field is E = σ / ε0. Σ is the amount of charge carried in the cloud per unit area. Then ...
σ = ε0E = (8.85 × 10 ^ 12 · s ^ 2 · c ^ 2 / kg · m ^ 3) (3000 · v / m) ≈2.7 × 10 ^ 8C · m ^ 2
At a glance.
Baili Qingfeng was waiting at the gate of Tiejianmen. This scene naturally aroused the suspicion of the two at the gate of Tiejianmen.
One of them was not looking well, so he asked his identity.
But when they saw the formulas on the wall, they instinctively felt that such an open-minded student could not be the enemy of their iron sword gate, plus it was raining outside ...
In the end, the man just glanced at him and hid under the eaves again, and ignored him.
Baili Qingfeng finished counting, looked at the door, not yet, then ...
Calculate the electric field strength on the surface of these rain drops.
"Zi!"
At this time, a car stopped again in front of the iron sword gate, and a middle-aged man got out of the company accompanied by a man.
"Nine brothers are here. Several other big brothers are already waiting for you."
One of the guards at the door stepped forward to help support the umbrella.
The man called Jiujie nodded and walked to the hospital.
"It's finally here."
Baili Qingfeng stopped the boring idea of ​​calculating the electric field strength and stepped forward to the gate of Tiejianmen.
When he moved, although he attracted the attention of another person, the person ignored it until he saw Baili Qingfeng went straight to their iron sword gate. When he arrived at the door, he scolded and said, "Which child is there?" This is not where you come, go on the side. "
But the man called Jiujie heard the sound, turned his head and took a look at Baili Qingfeng, and that was one glance. He thought of the information sent to them by the head of the meeting yesterday. The information said that Those who go to the city of Charya ...
"Bai Li Qing Feng !?"
Baili Qingfeng looked up and glanced at the man named Jiu Ge, then ignored the man's harsh drinking and closed the door that had just been opened.
he……
Brother Jiu, including two Iron Swordmen, was locked up in the martial arts hall.
"Hurry up! Go inside! Notify Lu's head and several other brothers, the enemy is here!"
The man called Jiu Ge changed his face, staring alertly at the closing Baili Qingfeng, slowly backing away.
The iron sword gate disciple who had previously reprimanded Baili Qingfeng flashed a dread in the eyes, quickly ran away, and retreated side by side with Jiu brother, watching Baili Qingfeng close the door, and then the copper hanging on the door The lock was used to lock it, and then the key was placed in the pocket of his pants.
"Bali Qingfeng, you are so brave, we didn't go to you, but you took the initiative to come to your door? Today I will let you come back! Brothers, go get the gun!"
A loud drink followed from the iron sword gate.
Suddenly ...
I thought these people would be rushing up in anger, and the Baili Qingfeng who had fisted his sword and fought him was obviously stunned. The next moment ...
Can't wait for the Iron Swordmen to gather ...
The umbrella fell.
"Oh!"
Pull out your sword and scabbard!

(I don't know why the formula can't be written, I won't write it later.)
