Thunderstorm

"Clang, clang."

The sound of the train wheels grinding against the rails echoed in his ears.

Baili Qingfeng sat on the train, closing his eyes to nurture his spirit.

The train ran for twenty-four hours. He had bought a ticket for the 2:30 AM train. It would take ten and a half hours to travel the four hundred kilometers to Miro City.

At this time, the train had too many stops along the way, severely affecting its speed.

Baili Qingfeng maintained this half-closed eye state, and time unknowingly passed to the dawn of the next day.

At this moment, there seemed to be a commotion on the train.

Baili Qingfeng opened his eyes and found that many people on the train were looking outside.

Baili Qingfeng glanced over and, with the help of the morning light on the horizon, discovered that a convoy of troop carriers, armored vehicles, and tanks was driving along a highway parallel to the railway tracks, forming a long line. Judging by the scale, there were definitely more than just one regiment.

However, the troop carriers, armored vehicles, and tanks were not the main point. The main point was…

The smell of gunpowder.

Baili Qingfeng saw the smell of gunpowder on these vehicles.

The army seemed to have just come from the battlefield. Baili Qingfeng had sharp eyes and could even see wounded soldiers with bandages and bloodstains.

The soldiers sat silently in the vehicles, mutely meeting the gazes of the people on the train, numb and silent, and in a moment, as the train tracks and the highway went from parallel to separate, they gradually moved away until they were completely out of sight, disappearing without a trace.

"Is there a war going on? Have the Aurora people attacked?"

"No way, we're in the south. The Aurora Empire is in the north. Even if there's a war, it wouldn't be with the people of the Aurora Empire."

"The scale of the army mobilized this time is not small. I just saw several thousand people, two or three regiments. If there really was a war, we should have known about it earlier."

"I heard a month ago that there were large-scale ground collapses in Li Ke County, suspected of Cavemen appearing… This place is not far from Li Ke County, could it be Cavemen?"

On the train, many people started to discuss, and even some people who were originally closing their eyes to nurture their spirit woke up at this time.

Baili Qingfeng listened, looked at the convoy that had disappeared from sight outside the window, and fell silent.

The Jiang Family, Eddie and his son, the Iron Sword Sect, these martial artists acting unscrupulously, and now the large-scale troop movements.

"Perhaps I need to change my understanding of the world… This world is far from as peaceful as I imagined."

The train arrived in Miro City at two o'clock in the afternoon, an hour late.

Compared to Xia Ya's clear skies and cloudless expanse, Miro City was raining.

A thunderstorm.

Seeming to foreshadow the occurrence of some event.

Baili Qingfeng got off the train and didn't dare to eat near the train station.

Eating a hundred-yuan plate of egg fried rice here was not a low-probability event.

He took a bus to a place one kilometer away from the Iron Sword Sect, had lunch, and watched the rain outside. He pre-paid five yuan from the confiscated 200,000 yuan extermination fund to buy an umbrella and walked towards the Iron Sword Sect.

The Iron Sword Sect was not built in the remote mountains and famous rivers, like Jiang's Martial Hall, the Iron Sword Sect also operates as a martial hall in Miro City.

However, compared to Jiang's Martial Hall, the Iron Sword Sect occupies a much larger area, with not only three small buildings, but also two basketball court-sized training grounds, as well as some equipment for exercise and activities.

When Baili Qingfeng arrived at the Iron Sword Sect, he found the atmosphere there was somewhat tense.

The gate was half-closed, and there were two sturdy-looking men under the eaves, guarding the place.

When Baili Qingfeng arrived, he saw a car stop in front of the Iron Sword Sect. Two vigorous men got out of the car, and another person came out with an umbrella to greet them: "Sixth Brother, Twelfth Brother, you're here. Now everyone's here except Ninth Brother."

"What happened? Why did Young Sect Master Lu summon us all here?"

"Didn't the Sect Master take the elite of the sect to Xia Ya yesterday? We lost contact with them this morning. Green Water Manor called around nine o'clock, something happened."

"Something happened? What happened!?"

"Let's go inside and talk!"

The group quickly entered the courtyard.

"There's still one person who hasn't arrived."

Baili Qingfeng thought for a while and decided to wait until everyone was there before taking action, to avoid any fish escaping the net.

But just waiting like this was very boring.

"The rain is heavy."

Baili Qingfeng looked up at the dark clouds above his head and the flashes of electricity from time to time.

Practicing the Thunder Sovereign Visualization Method made him extremely sensitive to the external electric potential.

"The current electric field is 3×103N/C. If I stand here without moving, it will definitely make the people of the Iron Sword Sect suspicious. So, in order not to startle the snake, let's 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.

Treating the cloud as an infinite plane, there are negative charges on the ground, and the electric field strength is E=σ/ε0, where σ is the amount of charge carried per unit area of the cloud, then...

σ=ε0E=(8.85×10^12·s^2·c^2/kg·m^3)(3000·v/m)≈2.7×10^8C·m^2

Crystal clear.

Baili Qingfeng stayed at the gate of the Iron Sword Sect, and this scene naturally aroused the suspicion of the two people at the gate of the Iron Sword Sect.

One of them looked unkind and was about to scold and question his identity.

However, when they saw the formulas on the wall, they instinctively felt that such a humble and studious student could not be an enemy of their Iron Sword Sect, plus it was raining outside...

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

Baili Qingfeng finished calculating and looked at the gate. He still hadn't arrived, so...

Let's calculate the electric field strength on the surface of these raindrops.

"Buzz!"

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

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

One of the guards at the gate hurriedly stepped forward to help hold up the umbrella.

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

"Finally, everyone's here."

Baili Qingfeng stopped his boring calculations of electric field strength, stepped forward, and walked towards the gate of the Iron Sword Sect.

His movement attracted the attention of another person, but that person ignored him until he saw Baili Qingfeng heading straight for their Iron Sword Sect. When he reached the gate, he scolded, "Which family's kid is this? This is not a place for you to come, go away."

However, the man called Ninth Brother heard the voice and turned to look at Baili Qingfeng. With just one glance, he suddenly thought of a document that the sect master had sent them during yesterday's meeting, which stated the person they were going to deal with in Xia City...

"Baili Qingfeng!?"

Baili Qingfeng looked up, glanced at the man called Ninth Brother, and then, ignoring the man's stern shout, closed the gate that had just been pushed open.

He...

Ninth Brother, including the two Iron Sword Sect members, were all locked inside the martial hall.

"Quick! Go inside! Notify Sect Master Lu, notify the other brothers, the enemy is here!"

The man called Ninth Brother's expression changed drastically, and he stared warily at Baili Qingfeng, who was closing the door, slowly retreating.

The Iron Sword Sect disciple who had scolded Baili Qingfeng earlier had a hint of fear in his eyes, quickly ran away, retreated side by side with Ninth Brother, and watched Baili Qingfeng close the door, then take the copper lock hanging on the door to lock it, and then put the key in the pocket of his pants.

"Baili Qingfeng, you really have a lot of guts. We didn't go looking for you, but you actually came to our door? Today, we'll make sure you don't return! Brothers, get the guns!"

A stern shout followed from inside the Iron Sword Sect.

Instantly...

Baili Qingfeng, who thought these people would swarm up in anger and fight him with their fists and swordsmanship, was obviously stunned. The next moment...

He couldn't wait for the Iron Sword Sect members to gather...

The umbrella fell.

"Clang!"

Drawing the sword, unsheathing it!

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