"Clang, clang."
The sound of train wheels rubbing against rails echoed in my ears.
Baili Qingfeng sat on the train with his eyes closed to relax.
The train runs 24 hours a day. He bought the ticket at 2:30 in the morning. It takes ten and a half hours to reach Miró City, which is about 400 kilometers away.
At this time, there are too many stops on the train, which seriously affects the speed of the train.
Baili Qingfeng kept his eyes narrowed, and the time passed unknowingly to dawn the next day.
At this time, there seemed to be a strange movement on the train.
Baili Qingfeng opened his eyes and found that many people in the car were looking outside.
Baili Qingfeng glanced at it, and with the morning light rising from the horizon, he discovered that on a road parallel to the railway tracks, troop carriers, armored vehicles, and tanks were lining up in a long queue. Judging from the scale, there were definitely more than 100 troops. A group.
However, personnel carriers, armored vehicles, and tanks are not the focus, the focus is...
The smell of gunpowder smoke.
Baili Qingfeng saw the smell of gunpowder smoke on these vehicles.
The army seemed to have just come off the battlefield. With Baili Qingfeng's sharp eyes, he could still see the wounded with bandages and stained with blood.
Soldiers sat silently on the train, looking at each other silently with the people on the train. They were numb and silent. For a moment, as the train tracks and highways moved from parallel to separate, they gradually moved away until they were completely invisible. , disappeared without a trace.
"Is there a war? The Aurora people are coming?"
"No way, we are in the south, and the Aurora Empire is in the north. The war is not with the people of the Aurora Empire."
"The size of the army dispatched this time is not small. What I just saw was several thousand people, two or three regiments. We should have known it was really a war."
"I heard a month ago that there was a large-scale subsidence in Li Ke County, and it was suspected that there were cave dwellers... This place is not far from Li Ke County. Could it be cave dwellers?"
In the car, many people started talking, even some people who had closed their eyes to relax were woken up at this time.
Baili Qingfeng listened, looked at the missing convoy outside the window, and fell silent.
The unscrupulous warriors of the Jiang family, Eddie and his sons, and the Iron Sword Sect are currently marching on a large scale.
"Maybe I have to change my understanding of the world... This world is far less peaceful than I imagined."
…
The train arrived in Miro at 2pm and was an hour late.
Compared to the clear and cloudless sky in Chara, it is raining in Milo City.
Thundershowers.
It seems to indicate that something is going to happen.
Baili Qingfeng got off the car and did not dare to eat near the train station.
It's not a small chance to eat egg fried rice for 100 yuan here.
He took a bus to a place one kilometer away from the Iron Sword Gate. He ate Chinese food and watched the rain keep falling outside. He advanced five yuan from the 200,000 collected to exterminate the sect, bought an umbrella, and held it up to the Iron Sword Gate. Go to the door.
Iron Sword Sect was not built in the barren mountains and famous rivers and swamps. Like Jiang's Martial Arts School, Iron Sword Sect also operated as a martial arts school to survive in Miro City.
It's just that compared to Jiang's Martial Arts School, Iron Sword Gate covers a much larger area. It has not only three small buildings, but also two training fields the size of basketball courts, as well as some equipment for exercise and activities.
When Baili Qingfeng came to Iron Sword Gate, he found that the atmosphere in Iron Sword Gate was a bit tense.
The door was ajar, but there were two strong-looking men standing guard under the eaves.
When Baili Qingfeng came, he saw a car stopped at the gate of Iron Sword Gate. Two men with strong looks got out of the car. There was also a man inside who held an umbrella and came out: "Brother Six." Brother Twelve, you are here, now everyone is here except Brother Ninth."
"What happened? Why did Master Lu call us all here?"
"Didn't the leader take the elite members of the sect to Xia Ya yesterday? I have been contacting him since this morning. I got a call from Green Water Villa at around nine o'clock. Something happened."
"Something happened? What happened!?"
"Let's talk after we get in!"
The group quickly entered the courtyard.
"There's another one yet to come."
Baili Qingfeng thought for a while and decided to wait until everyone had arrived before taking action to avoid anything slipping through the net.
But just waiting around is boring.
"It's not raining lightly."
Baili Qingfeng raised his head and looked at the dark clouds above his head and the lightning that shone from time to time in the clouds.
Practicing the concept of Thunder Lord makes him extremely sensitive to the electric potential of the outside world.
"The current electric field is 3×103N/C. If I stand here and don't move, the people at Iron Sword Gate will definitely be suspicious. So, in order not to alert the snake, find something to do and calculate the amount of charge in the thundercloud. .”
Baili Qingfeng picked up a pebble, came to the wall, used the wall as a blackboard, and started calculating.
Treat the cloud as an infinite plane, there is negative charge on the ground, the electric field size 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
It's clear at a glance.
Baili Qingfeng was waiting at the door of Iron Sword Gate. This scene naturally aroused the suspicion of the two people at the door of Iron Sword Gate.
One of them looked evil, so he yelled and asked for his identity.
But when they saw the formulas on the wall, they instinctively felt that such an open-minded and studious student could not be their Iron Sword Sect's enemy. Plus, it was raining outside...
In the end, the man just glanced at him, hid under the eaves again, and paid no attention to him.
Baili Qingfeng finished his calculations and looked at the door. He hadn't come yet, so...
Let’s calculate the electric field intensity on the surface of these raindrops.
"Zi!"
At this time, a car stopped in front of the Iron Sword Gate again, and a middle-aged man got out of the car accompanied by someone.
"Brother Ninth is here, the other elder brothers are already waiting for you inside."
One of the guards at the door quickly stepped forward to help hold the umbrella.
The man known as Brother Nine nodded and walked into the courtyard.
"Finally we're all here."
Baili Qingfeng stopped his boring thoughts of calculating the electric field strength and stepped forward to the door of Iron Sword Gate.
His movement attracted the attention of another person, but that person ignored him until he saw Baili Qingfeng coming straight to their Iron Sword Gate. When he reached the door, he scolded: "Which kid is this? , this is not the place you came from, go ahead."
However, when the man named Jiu Ge heard the voice, he turned his head and glanced at Baili Qingfeng. With just this glance, he suddenly thought of a piece of information that the boss sent them during the meeting yesterday. The information said that The people who went to Char City to deal with...
"Baili Qingfeng!?"
Baili Qingfeng raised his head and glanced at the man named Jiu Ge. Then, ignoring the man's fierce shouting, he closed the door that had just been pushed open.
he…
Ninth Brother, including two members of the Iron Sword Sect, were all locked up in the martial arts hall.
"Quick! Go inside! Notify Head Lu and the other brothers that the enemy is coming!"
The face of the man known as Brother Nine changed drastically. He stared at Baili Qingfeng who was closing the door with a wary expression, and slowly backed away.
A trace of fear flashed in the eyes of the Iron Sword Sect disciple who had previously scolded Baili Qingfeng. He quickly ran away and retreated side by side with Brother Jiu. He watched helplessly as Baili Qingfeng closed the door and then removed the copper hanging on the door. He took the lock and locked it, then put the key in the pocket of his pants.
"Baili Qingfeng, you are so brave. We didn't go looking for you, but you actually came to our door? Today, you will never come back! Brothers, go get your guns!"
A sharp shout followed from inside the Iron Sword Gate.
Suddenly…
I thought these people would swarm him out of anger. Baili Qingfeng, who used boxing and sword skills to fight him, was obviously stunned. The next moment...
I can't wait any longer for the Iron Sword Clan members to gather...
The umbrella falls.
"Qiang!"
Draw your sword and unsheath it!
