I started with a portal, then turned around and handed it over to the nation.

After disinfection, medical staff began drawing blood, measuring body temperature, and collecting oral and nasal samples.

On the other side, several engineering vehicles drove in, and huge inflatable tents were quickly erected on an open space not far from the training ground, forming a temporary isolation camp.

A member of the Tigers looked at the row of tents and nudged his comrade next to him.

"Hey, judging by this situation, we'll probably have to make do with spending the night on this training field."

The other teammate shrugged nonchalantly and responded with a smile:

"It's better than sleeping in a swamp, right? At least we have a bed! Maybe we'll even get a midnight snack!"

"Haha, you're right! And there's meat too!"

"Hahaha~"

Tired but reassuring laughter echoed throughout the temporary tent area.

Inside the central command center, the live feed of the training ground occupies the most prominent position on the huge main screen.

General Zhao Zhenguo stared at the main screen. The soldiers on the screen were swaying back and forth, but their expressions were relaxed.

Beside him, Professor Sun Dehai could no longer contain himself.

The old professor paced back and forth, rubbing his hands together, his neck stretched out, his eyes fixed on the carefully moved sample collection boxes in the corner of the screen.

"General! General!"

Sun Dehai's voice carried a childlike urgency. He moved closer to Zhao Zhenguo, lowered his voice, but couldn't hide the excitement on his face.

"Samples! Where are the treasures? What good stuff did they bring back this time? Let me go see!"

Zhao Zhenguo slowly turned his head, not looking at Sun Dehai, his gaze still fixed on the screen, falling on a soldier being helped up, the soldier with a silly grin on his face.

"Old Sun."

The general's voice was not loud, but it carried an undeniable composure.

"Calm down."

The general finally turned his gaze to his old partner, his eyes serious.

"They just came back from the brink of death, barely escaping with their lives. We can't let them feel like they're just tools for transporting samples the moment they land."

Zhao Zhenguo paused, then emphasized:

"Don't let the soldiers lose heart. Their lives are more important than any experiment."

"Let's wait until the initial tests are completed, and it's confirmed that there are no unknown viruses or bacteria present. Once everything is safe, then we can discuss the samples."

The urgency on Sun Dehai's face froze instantly, then turned into a hint of shame.

The old professor stopped, scratched his already thinning hair somewhat awkwardly, and let out a long sigh.

"Sigh... I was too anxious, I was too anxious."

The old professor took two steps back, found another chair and sat down. Although he still glanced at the screen from time to time, he had become quiet.

As Zhao Zhenguo watched him sit down, the tense lines of his face softened slightly.

He picked up the internal communication microphone on the table and dialed a number.

"Comrade Ye Qing? This is Zhao Zhenguo."

A calm female voice came from the other end of the phone: "General, please speak."

"The team members have all returned safely. Once their quarantine and check-up are over, we will arrange a comprehensive psychological stress test for them tomorrow."

Zhao Zhenguo looked at Lin Mo, who was having blood drawn but whose eyes were looking into the distance, in the center of the screen, and added a sentence.

"Everyone, not one can be missing. Especially Lin Mo, he is a key person to watch."

"Understood." Ye Qing's voice was concise and professional, without the slightest hesitation.

The call has ended.

As soon as Zhao Zhenguo put down the microphone, the medical team's report came through the public communication channel in the command center.

"Reporting to the commander-in-chief, the air sample test at the site is safe, and no abnormal microorganisms were found."

"All team members showed no abnormalities in their initial physical examinations, and all blood samples have been collected and sent to the P4 laboratory for in-depth analysis."

The report paused briefly, then continued.

"Among the combat personnel, the member codenamed 'Nail' had a severe injury to his right arm, but after examination, the wound has fully healed and no sequelae were found."

"Please proceed to the next step: transfer all personnel to a temporary isolation area for 24-hour observation."

Zhao Zhenguo picked up the microphone, pressed the call button, and said only two words.

"agree."

The order has been issued.

On the training ground, Lin Mo, Long Fei, and the members of the three special operations teams were guided by medical personnel into the white temporary tents that were quickly set up.

Everything they brought back underwent a much more rigorous process.

Several staff members wearing the highest level of protective clothing carefully transferred each sample bag and each piece of equipment contaminated with the alien substance using specially made sealed boxes.

Lin Mo's tactical recorder, which was hanging around his neck, was placed separately in an anti-static, shock-resistant safe and escorted away from the scene immediately.

The items brought back were sorted and sealed away one by one.

Plant samples, air samples, and even goblin blood and minotaur flesh scraped onto the soldiers' combat uniforms were all collected.

Soon, these samples from another world appeared in the deepest part of the base, in a heavily guarded isolation laboratory.

The heavy alloy door closed silently behind us.

The laboratory was brightly lit, and dozens of scientists were already in their positions.

The robotic arm precisely delivers the sealed samples into individual isolation worktables.

An exotic plant covered in dew was picked up and placed under a microscope.

A drop of dark green goblin blood was injected into the analyzer.

On the main computer screen, countless lines of complex data began to scroll rapidly. Everyone held their breath as a tense analysis began in silence.

……

On the other side, inside a temporary isolation tent.

The atmosphere is much more relaxed.

The tent wasn't big; it was just big enough to accommodate a small team.

There were several cots inside, simply furnished but clean and tidy.

A logistics worker walked in carrying a metal box, and opened it amidst the curious gazes of the crowd.

Inside, a row of smartphones were neatly stacked.

"General Zhao has given special approval."

The logistics staff's voice was tinged with laughter:

"Each person has five minutes to call home and let their family know they are safe. After you finish, your phones will be collected."

There was a moment of silence in the tent, followed by a suppressed cheer.

One by one, the soldiers stepped forward and took out their cell phones, which had been switched off for a long time, from the boxes.

Lin Mo also got his.

He walked to the cot in the corner, sat down, and pressed and held the power button.

After the familiar boot animation, the screen lights up, and countless unread messages and missed call notifications flood in instantly.

Lin Mo ignored all that and swiped his finger across the screen to find his family's contact information.

He hesitated for a moment, then opened the chat application.

His fingers hovered over the keyboard for a moment before finally typing a single, simple line.

"Dad, Mom, I was on a closed mission a few days ago, and it just ended. Everything went smoothly, and I'm back safely."

"I still have some mission reporting to do at the base. I'll come back to see you after I'm done with this."
