The Unkillable Swordsman

Bang, bang, bang.

The sound of train wheels rubbing against rails echoed in my ears.

Baili Qingfeng sat on the train with his eyes closed and rested.

The train runs 24 hours a day, and he bought a ticket for 2:30 in the morning, and it takes ten and a half hours to reach the 400 kilometers from Miro 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 it was the dawn of the next day before he knew it.

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 dawn of the sky, he found that on a road parallel to the railroad tracks, there were troop carriers, armored vehicles, and tanks lined up on the road. Judging by the scale, there were definitely more than one a regiment.

However, personnel carriers, armored vehicles, tanks are not the point, the point is...

The smell of gunpowder.

Baili Qingfeng saw the smell of gunpowder smoke on these vehicles.

The army seemed to have just come off the battlefield, Baili Qingfeng had sharp eyes, and he could still see the wounded with bandages and blood.

Soldiers sat silently on the train, silently staring at the train personnel, numb and silent, and for a moment, as the train tracks and roads went from parallel to separate, they drifted away until they were completely invisible , disappeared without a trace.

Is it a war? Are the Aurora people coming?

No way, we are in the south, and the Aurora Empire is in the north. We are not fighting against the people of the Aurora Empire.

The scale of the army dispatched this time is not small. The one I saw just now has thousands of people, two or three regiments. We should have known if it was really a war.

I heard about a month ago that there was a large-scale land subsidence in Like County. It seems that there are burrowers infesting... This place is not far from Rike County. Could it be burrowers?

In the car, many people began to discuss, even some people who had closed their eyes and rested their minds woke up at this moment.

Baili Qingfeng listened, looked at the disappearing convoy outside the window, and fell silent.

The unscrupulous warriors of the Jiang family, Eddie and his son, and Tie Jianmen are now 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 City at two o'clock in the afternoon, an hour late.

Compared with Char's clear sky and cloudless sky, it is raining in Miro City.

thunderstorm.

It seemed to indicate that something was going to happen.

Baili Qingfeng got out of the car, not daring to eat near the train station.

It is not a small probability to eat fried rice with eggs for 100 yuan a meal here.

He took a bus to a place one kilometer away from Tiejianmen, ate Chinese food, and watched the rain keep falling outside. He paid five yuan in advance from the 200,000 yuan collected for the destruction of the gate, bought an umbrella, and held it to Tiejianmen. door to go.

Tiejianmen was not built in the barren mountains and famous rivers and rivers. Like Jiang's Martial Arts, Tiejianmen also survived in Miluo City as a martial arts gym.

It's just that compared to Jiang's martial arts gym, Tiejianmen covers a much larger area. There are not only three small buildings, but also two training grounds the size of basketball courts. In addition, there are some equipment for exercise and activities.

When Baili Qingfeng came to Tiejianmen, he found that the atmosphere in Tiejianmen was a little tense.

The door was ajar, but there were still two strong-looking men waiting and guarding under the eaves.

When Baili Qingfeng came, he saw a car stopped at the gate of Tiejianmen. Two fierce men got out of the car, and a man came out with an umbrella: Brother Six Twelfth Brother, you are here, now everyone is here except Ninth Brother.

What happened? Why did Master Lu summon us all here?

Didn't the head take the elite of the sect to Shaar yesterday? He has been in contact since this morning. He called from Green Water Villa at nine o'clock. Something happened.

What happened? What happened!?

Go in and talk!

A group of people quickly entered the yard.

There's one more that hasn't come.

Baili Qingfeng thought about it, and decided to wait until all the people arrived before making a move, so as not to slip through the net.

But it's boring just waiting.

It's raining.

Baili Qingfeng looked up, looking at the dark clouds above his head, and the lightning flashes from the clouds from time to time.

Practicing the concept of thunder dominance made him extremely sensitive to external electric potential.

The current electric field is 3×103N/C. If I stand still here, the people in Tiejianmen will definitely become suspicious. So, in order not to startle the snake, find something to do, and calculate the amount of charge in the thunderstorm cloud. .”

Baili Qingfeng picked up a small stone, went to the side of the wall, and used the wall as a blackboard to calculate.

Considering the cloud as an infinite plane, there is a negative charge on the ground, and the electric field is E=σ/ε0, where 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 is clear at a glance.

Baili Qingfeng was waiting at the gate of Tiejianmen, and this scene naturally aroused the suspicion of the two people at the gate of Tiejianmen.

One of them had a bad complexion, so he would scold and question 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 enemy of Tiejianmen, plus it was raining outside...

In the end, the man just glanced at him, hid under the eaves again, and ignored him.

After Baili Qingfeng finished his calculations, he looked at the door and found that he hadn't come yet, so...

Then calculate the electric field strength on the surface of these raindrops.

Zi!

At this moment, a car stopped in front of Iron Sword Gate again, and a middle-aged man got out of the car accompanied by another person.

Ninth Brother is here, the other big brothers are already waiting for you, Ninth Brother.

One of the guards at the gate hurried forward to help hold the umbrella.

The man called Brother Nine nodded and walked into the courtyard.

It's finally here.

Baili Qingfeng stopped the boring idea of ​​calculating the electric field strength, stepped forward, and walked towards the gate of Tiejianmen.

His movement attracted another person's attention, but that person ignored it until he saw Baili Qingfeng coming straight to their Tiejian Gate, and when he reached the door, he scolded: Which family's kid? , this is not where you came from, go aside.

On the contrary, the man called Ninth Brother heard the voice and turned his head to look at Baili Qingfeng. With just such a glance, he suddenly thought of a document sent to them by the head of the meeting yesterday. Those who went to Char City to deal with...

Baili Qingfeng!?

Baili Qingfeng raised his head, glanced at the man named Brother Jiu, and then, ignoring the man's stern shout, closed the door that had just been pushed open.

he……

Nine Brothers, including the two Iron Sword Sect members, were all locked in the martial arts hall.

Quick! Go inside! Inform Head Lu and the other brothers that the enemy is coming!

The man called Ninth Brother's face changed drastically, he stared at Baili Qingfeng who was closing the door with a wary face, and slowly backed away.

And the Tiejianmen disciple who reprimanded Baili Qingfeng earlier had a flash of fear in his eyes, and quickly ran away, and retreated side by side with Brother Jiu, watching Baili Qingfeng close the door, and then put the copper hanging on the door. The lock was locked, and the key was put in the pocket of his trousers.

Baili Qingfeng, you are so courageous. We didn't go looking for you, but you actually sent it to your door? I will let you come and go today! Brothers, go get the gun!

A stern shout followed from inside the Iron Sword Gate.

Suddenly...

Thinking that these people would swarm up in anger, Baili Qingfeng, who was fighting with him with boxing and sword skills, was obviously stunned. The next moment...

Don't care about waiting for the iron swordmen to gather...

Umbrella falls.

Clang!

Draw your sword and unsheath it!
