"I know you're smart, but even tigers have their moments of weakness, right?" Yu Wei pinched the bridge of his nose, slowed his speech, and gently instructed, "If there's anything you don't know how to operate the mecha, Xiao Zhen can teach you. Just be careful in everything you do..."

"Okay, okay, I know. My signal is bad here, I'll talk to you later..."

Zhou Siyu chuckled and quickly hung up the communicator.

Yu Wei is only thirty years old, how come she's already going through menopause?

“You…” Looking at the extinguished communicator, Yu Wei shook his head helplessly and muttered softly, “This guy, he’s not happy to hear another word.”

After gathering his thoughts, Yu Wei returned to the tent to continue discussing the new marching plan.

After finishing the cookies, Zhou Siyu felt it was necessary to take a nap. After releasing the patrol robot, she took a light nap while resting her head on a milky steamed bun.

"Boom..."

"Bang..."

"Splash..."

A loud crash jolted the two awake from their sleep; the sounds of tables and chairs collapsing and glass shattering created a rather unpleasant symphony.

Yu Zhen stared wide-eyed, her mind blank, before slowly coming to her senses after a dozen seconds.

"Holy crap! Those guys with their concrete-and-gravel heads actually managed to open it?"

"Um……"

Zhou Siyu patted her dazed head, quickly regaining her senses. Listening to the clanging and banging sounds, she sighed.

It looks like a lot of valuable things have been destroyed; there's no point in exploring that place anymore.

"Let's go." Zhou Siyu patted Yu Zhen and helped him stand up. "There's no point in staying here any longer. Let's go to the next experimental area."

Back then, the Alliance obtained the blueprints for the laboratory from one of the heads of the Etolan Laboratory. The blueprints included not only the above-ground parts but also the underground parts. However, this information has always been classified as top secret, and only people of Yu Zhen's caliber have the right to access it.

Taking advantage of the moment when Zhou Siyun and her group entered the laboratory, the two humans and the wolf-fox quietly crept along the wall into the next experimental area.

If the warehouse in front was a miscellaneous storage area, then the warehouse here was a real storage room. The name of each room was clearly written on the bronze plaques, and the name of the person in charge and the purpose of the room were also written on the bronze plaques by the doors.

Ancient bio-locks could not stop new technology. With Zhou Siyu's nimble hands, the heavy bronze door slowly opened, revealing a white iron door behind it.

The white iron gate slid open and then closed quickly, and incandescent lights lit up one by one, the glass shards scattered on the ground reflecting a blinding light.

"No way, they didn't intend to leave any room for future generations to study this."

Yu Zhen kicked the pile of debris and looked around the empty room.

Besides the shards of glass scattered all over the ground, there were mostly corpses lying haphazardly in various positions. Because the temperature was too low, there were no rotting bodies, and there was nothing that looked like an experimental subject.

"This is a virus storage room, be careful."

Zhou Siyu turned on the gas monitoring system and found the only thing glowing green in the corner amidst a sea of ​​red light.

The previous warehouse showed no signs of being vandalized, but this seemingly enclosed storage room was in complete disarray. Even more surprisingly, the corpses, each with a different death, were all looking in the same direction—the white iron door.

"If you ask me, this person in charge is utterly inhumane."

Yu Zhen squatted down, took out a dagger, cut off a piece of skin from a corpse, and carefully put it into a sealed bag.

“This is a virus storage room. None of these people are wearing protective suits. It’s obvious that their superiors don’t want them to leave alive.”

Zhou Siyu kicked aside the corpse blocking her way, walked to the corner, and picked up the item that the system had deemed safe.

It was a small, empty, sealed glass jar, about the size of a palm, and it looked like there was nothing inside.

Zhou Siyu gently tapped the tube to shake off the dust, then put it into the storage room.

"These people were supposed to be responsible for destroying the stored virus before the Allied forces arrived, but they were trapped inside and died afterward. It's truly..."

“There’s another possibility.” Zhou Siyu interrupted Yu Zhen, pointing to one of the corpses covered in black spots and slowly said, “They were the last batch of experimental subjects.”

The management of the Etolan Laboratory was chaotic in its later stages. In addition to the defecting experimental personnel, a considerable number of civilians who were intended to be used for experiments also escaped. With the Alliance forces pressing in, it was not impossible that some low-level experimental personnel were used as experimental subjects.

However, what is puzzling is why the laboratory managers were unwilling to give up the experiment despite the internal and external troubles.
