Train Survival: You're really trying to survive!

While Su Li was rambling on and on, the jewelry was already finished.

Song Mingyu placed the finished necklace in her palm.

This is a round pendant. Inside are pieces of zombie flesh, and on the outside is a refined crystal of the zombie virus, combined with magical runes outlined in gold thread.

Song Mingyu carefully sensed it and said, "There is some kind of fluctuation being released here. The source of this fluctuation is the virus crystals and flesh."

"The nature of this fluctuation has some characteristics of the psychic system," Sun Lili added to her discovery. "I'll study it tonight."

"Isn't it possible now?" Ivan asked.

“That won’t work. We need to record and analyze this fluctuation first. It will take some time.” Song Mingyu shook her head. “Ivan, you use the workshop’s workbench to record the fluctuation. I’ll take one to the biological laboratory to record the data on the blood, flesh, and virus crystals.”

Sun Keke added, "The runes on this pendant are very strange. It will take me several hours to decipher them."

Su Li clapped her hands. "Then let's continue exploring. We'll study the data more carefully tonight when it comes out."

The group returned to the building.

This time, they went straight to the first floor.

Then, they saw a blast door that looked like a roller shutter. Below the blast door, a large number of zombies were pounding on it.

"So that's why there are so many zombies in this building. We can't get out."

After dealing with the zombies, Su Li and his team began searching for hidden underground spaces.

The method for finding it is also very simple.

Divination!

Su Li and the others have confirmed that there is an entrance to an underground space here, and it is only a matter of time before they find it. In this situation, divination consumes very little energy.

Sun Keke closed her eyes, and after a while, she walked to the middle of the toilet.

After using magic energy to blast through the wall, a large hole was revealed.

"There's a small elevator shaft sandwiched between the men's and women's restrooms."

Su Li poked her head out, took out a glow stick, broke it in half, and the glow stick emitted a green glow. Su Li threw the glow stick into the elevator shaft.

A moment later, the glow stick bumped into the elevator below.

"It's about 40 meters deep. No wonder Li Feng said there was an unusually large amount of unearthed material here. They dug this deep."

Generally speaking, each floor is 3 meters high, meaning the underground excavation reached a depth equivalent to more than 10 stories. This is comparable to the depth of the above-ground portion.

Sofia felt like she was being watched. She looked up and noticed a camera that was in operation.

"We've been discovered."

Su Li shrugged. "An automated thermal imaging monitor can keep track of this entrance. Under the control of the program, it doesn't even require someone to keep an eye on it. It's only a matter of time before it's exposed."

This is why Su Li didn't stop Sun Keke from exploding earlier.

Sun Keke took out a golden apple, wiped it clean, and placed it on her waist. In case of any unexpected events, this golden apple would definitely give the other party a pleasant surprise.

"Let's go down."

Su Li jumped down into the elevator shaft, using her legs to gain momentum in the air, and successfully landed a little above the elevator shaft.

Su Li swung her greatsword around, severing the elevator cables with sword energy, causing the elevator to plummet several meters downwards. Then, a layer of ice blocked the elevator shaft, landing her companions on the ice.

Ivan put on his shield and then kicked open the closed elevator door.

"boom!"

"Da da da da da!"

"boom!"

A burst of gunfire and the sound of bombs exploding rang out, but within seconds, everything inside went out.

Ivan, holding his shield, led the way, guiding Su Li and the others inside.

In the distance, Sun Lili put her hands on her hips and made a V sign at Su Li and the others.

Behind her were several damaged objects that looked like hoverboards. Underneath these hoverboards were ammunition boxes, and on top of them were fixed machine guns.

"[Space system, so useful!]" Su Li exclaimed.

[Hehe, of course! I've developed a new feature: mini teleportation portals. We can unlock them tonight during our fight!]

Sun Keke withdrew her little feet, which were clad in small leather shoes, leaving her older sister to hug her legs and cosplay as Talking Tom.

Su Li was speechless for a few seconds, suppressing the little excitement in his heart. Sun Lili always managed to come up with some new ways to play. He felt like he was about to fall behind this girl.

Damn it, there's a well that connects to the Sea of ​​Hearts, and we can learn technology from the humanoid stars. The advantage is too great!

"Sigh~" Sophia sighed wearily.

Before them lay a relatively small underground platform. The entire space was approximately 1000 square meters and 10 meters high. A brand-new train was parked on the platform; judging by the overhead contact lines, it was clearly powered by electricity. The train was matte black and looked like a silent behemoth.

There were also some forklifts and cranes around. Su Li looked to the other side and saw an entrance that was clearly for vehicles, as well as several large elevators, indicating that there was also a freight passage here.

There were about 20 guard machines here, but Sun Lili wiped them all out with a single, devastating attack.

Su Li walked to the empty guard room. Judging from the dust on it, the place had been abandoned for a long time.

“I found an employee handbook.” Sophia picked up a small blue-covered notebook. “This is Tianmu Medical University Station, a place that uses the medical university as a cover to provide various medical supplies to the main base.”

"Looks like we'll be taking this train," Su Li said in a low voice, leading her teammates onto the train.

Once inside the train, Su Li and the others discovered that it was out of power. Wait, there was power here; the people behind the scenes must have cut off the power.

This was no problem for Su Li and his team.

Su Li sent a message to Zhang Qiang, requesting that Zhang Qiang provide her with a decoder.

Decoding the Intrusion Machine

[Iron Grade]

[Includes a complete decoding device, highly versatile, capable of unlocking most artifacts created by low-level mechanical civilizations.]

The technology in this world has not yet advanced to the point where cities can be built on satellites; it remains within the realm of primitive mechanical civilization.

After the machine was connected, the train was powered on shortly afterward.

Unfortunately, they immediately noticed something was wrong and physically cut off the power and network to the area. The tram, relying solely on its own battery, obviously couldn't start.

But it doesn't matter, Su Li and the others are not ordinary people.

Sophia located the train's power unit and began enchanting it. Ten minutes later, the power unit was covered in purple lightning runes. Driven by the runes, the train started successfully, albeit slowly.

The train moved slowly along the tracks, heading deeper into the research institute. The carriages were dimly lit, with only occasional flashes of emergency lights illuminating their faces. After some time, the train finally came to a stop.
