The adjustment he made to the delivery vehicle yesterday wasn't just a simple operational check; in fact, he removed the vehicle's output limiter. Today's delivery vehicles can easily exceed their maximum speed limit, just like those off-brand e-donkeys from the early 2000s, which could be driven as fast as cars simply by cutting two wires.

"Oh~" He used the computing power of the onboard computer to speed through winding tunnels and completed difficult tailswinging maneuvers safely and smoothly - these were things that previous stunt drivers could not do.

The tunnel lights turned into shooting stars in Chen Baoding's eyes, then swayed and swayed by the vehicle's wake. It was as if a monster was roaring in the tunnel, the howling sound coming from far away and then from near to far.

Of course, Chen Baoding doesn't have that kind of driving skills. All of this depends on some artificial intelligence of unknown origin running on the onboard computer.

The 40-ton truck sped through the narrow tunnel at a speed of 80 kilometers per hour. It took him only ten minutes to reach the mining area's main engine room.

The explosion-proof door of the machine room was closed as usual, and several apprentices who looked very tired were guarding it.

The transporter began to slow down slowly, and Chen, who was inside, didn't feel much acceleration. The vehicle headed straight for the blast-proof door, stopping just as the apprentices tried to avoid it.

"Where are Ma Si and the others?" Chen Baoding shouted to the apprentices using the car loudspeaker.

"They are still inside!" an apprentice answered weakly. They had been here for almost half a day and had used up the last of their portable food.

"This is strange." Chen Baoding thought to himself, then he shouted on the microphone: "You guys go to the back of the car and rest for a while, I'll go inside and take a look."

He turned off the engine of the transport vehicle, then pulled out his pass and waited until all seven apprentices were on the vehicle before climbing down in his slippers.

The explosion-proof door of the computer room must be opened with a pass, and the permission must be Class B or above.

Chen Baoding stuffed the pass into the electronic lock next to the explosion-proof door, but there was no movement.

"What's going on? I didn't plug it in the wrong way."

He tried a few more times, but this time even the electronic lock's light didn't work. Apparently, the damn thing had broken down again, for the nineteenth time this month.

"Fuck! What on earth did Qi Heng repair?"

Chen Baoding cursed and walked back to his truck. Fortunately, he hadn't forgotten to bring his toolbox before setting off. He planned to use the folk method Qi Heng taught him to open the broken door.

The principle behind electronic locks has remained unchanged since their invention. Simply locate the two key wires, ensure they're powered, and short-circuit them a few times to unlock the door with a high probability. If the door doesn't open, it's likely due to insufficient voltage.

After fiddling around for a while, Chen Baoding skillfully opened the explosion-proof door. While disassembling it, he discovered that the two wires had been violently disassembled many times. If it happened twice more, the door lock would be completely scrapped.

He opened the explosion-proof door, then found two stones to block the rebound system to prevent himself from being locked in again.

The computer room was completely silent, save for the constant flow of a special liquid in the heat dissipation pipes. The four mainframe computers in the center of the room were still quietly calculating something, their indicator lights flashing constantly, but Chen Baoding knew nothing about it.

"Old Ma~"

"Master Qi~"

He shouted loudly in the computer room, but no one responded.

Maybe they all went back to rest. Really, I didn’t even bother to tell those apprentices!

When Chen Baoding passed by a square device placed against the wall, he found that a lot of charred material was spilled on it.

It looks a bit like carbonized rubber.

He thought he had the upper hand on them—open flames were strictly prohibited in the machine room. He figured they were too lazy to clean up the scattered cable casing, so they simply set it on fire. The smell of burning synthetic rubber was quite strong. They probably left without saying goodbye to avoid arousing the apprentices' suspicion.

Mention it to Xiao Zhang when you get back. This is a very good reason and you can probably get a lot of salary deducted!

He took out his terminal from his pocket, took several photos of the "evidence", and then happily returned to the transport vehicle without closing the explosion-proof door, and prepared to return in broad daylight.

Chen Baoding planned to return by the same route. Although he was already familiar with the route, he was carrying several "outsiders" with him. To maintain his dignity, he had to crawl back at the snail's pace prescribed by the mine regulations. Fortunately, the onboard computer had memorized the route, so he didn't need to manually control the vehicle on the way back.

The rear compartment of the car was separated from the driver's cab by a small door, making it easy to enter and exit. Chen Baoding opened the door and shouted to the back, "Everyone, sit down inside. No talking, no touching anything inside, no vomiting due to motion sickness, no... Why are you missing someone?"

"It's Xiaoxi! He just..."

An apprentice in the car wanted to explain, but was immediately interrupted by Chen Baoding: "I told you to stay in the car! If he doesn't come, let him walk back by himself! If it happens again, let Zhang, Mr. Zhang, fire him!"

His trick of using the power of a tiger to bully others was quite effective. Several apprentices were so frightened that they dared not even breathe, and all lowered their heads, pretending to be ostriches. This made Chen Baoding very satisfied. He was about to continue his lecture when a strong smell of cigarette smoke entered his nose.
