Jian Na groggily opened her eyes to find the room engulfed in darkness.

She clutched her throbbing forehead, fumbling to turn on the bedroom's chandelier. As she gazed at the familiar furnishings in her home, she gradually calmed down.

Since the cruise ship was unlocked in the morning, she had been feeling dizzy.

After the temporary epidemic transport vehicle brought her home, Jian Na slept until now without a break.

Taking out her phone.

She browsed through the news related to the Platinum Star Cruise. Looking at these familiar yet strange reports, she could hardly believe that this was all linked to her. No, to be precise, she was the one who personally resolved this massive infectious disease crisis!

"Public health... 7472, hissing..."

Remembering all this, Jian Na's brain ached. She got up, found some painkillers in the drawer, and while drinking water, she went to the desk in her bedroom.

The desk was densely packed with all sorts of nursing books: physiology, pathology, medical psychology, preventive medicine, and emergency nursing...

These were all the professional books she needed to study for her undergraduate nursing degree, though there wasn't "Public Health," but "Preventive Medicine" had a lot of overlapping knowledge with it. The former focused more on command management, while the latter emphasized clinical theory.

Maybe I reviewed it when I was preparing for the hospital exam before...

Jian Na pulled out "Preventive Medicine" and flipped to a random page, which read: Section Three (Environmental Pollution and Health Effects). Suddenly, a blaze of knowledge about public health and disease prevention began to swiftly return to her mind.

Finally, it was the evening of the seventh day.

Gu Ji sat on the bed in the temporary dormitory at the base, eagerly opened the game's inventory, where two iron-framed wooden chests stood ready, seemingly waiting for him to unlock them.

[Would you like to spend 2 Crisis Points to open all chests?]

[Yes!]

He rubbed his palms together. The next second, the two chests began to shake violently, and as the wood cracked, blinding white light burst forth from inside:

[Congratulations on obtaining the White Marks: Combat Mastery (Minor), Special Driving Mastery (Minor)!]

Gu Ji's eyes lit up instantly.

These two marks were almost the most practical rewards in the cruise level; it seems limited chests indeed yield good things easily!

Unfortunately, he only had one slot left; once it was embedded, replacing with a new mark would cost 1 Crisis Point. If two marks were moved simultaneously to the third mark, it would trigger synthesis.

Gu Ji didn't have enough points for synthesis yet, and even if he did, he didn't dare to gamble recklessly.

After hesitating for a moment, he decided to choose Combat Mastery. Compared to driving, combat had broader applicability.

With the boost of 10% combat level, combined with the Flying Tiger Team's CQC skills, his close combat level, especially in cold weapons, was elevated to a new level.

...

...

"Clear!"

Gao Bo swiftly scanned the alley with his gun.

At the police training base, today's practical police training topic was breach and rescue hostages. Gu Ji, as the second practice team, was leading his team through the simply constructed "murder house" at the base.

After more than ten days of intensive professional training, all police officers were well into the state.

But thanks to the continuous attribute enhancements of the game system, Gu Ji's skill level had improved the fastest.

As he approached the core attack point,

He extended his arms, palms facing the team, and the squad immediately halted in place, "Observer!"

A round-faced police officer wielding a periscope device resembling a rifle inserted the thin metal periscope like a bamboo stick through the gap under the door. As the dark images gradually faded, several pairs of boots appeared in the center of the screen.

He carefully retracted the device and spoke in a hushed voice:

"There are two robbers in the room, both on the left side, and they have a hostage."

"Prepare to breach!"

Gu Ji decisively issued the order. A tall, muscular police officer hefted a heavy cylindrical black battering ram and quietly approached the wall by the room door.

This was one of the practical techniques under assessment today: cold breach entry.

Anyone familiar with tactical assault knows there are two types of breaching methods.

Cold Breach: Technical opening, battering ram, hydraulic pliers, crowbar, sandless gear saw, etc. The advantage is it's relatively safe, with low technical requirements, but less efficient in breaking thick metal security doors.

Hot Breach: Shotgun, C-series explosive demolition, and water shot breach. The advantage is there's no door that can't be breached, but it requires high technical skills and has a risk of self-injury.

Each has its pros and cons, and the choice depends on one's tactical level and the actual situation on site.

And the door in front was a wooden door.

"Three, two, one!"

Bam—!

With the final command shouted out, the burly police officer swung the battering ram forcefully against the wooden door's lock.

In an instant, wood chips flew, a sliver of light appeared through the door crack, and Gao Bo and Gu Ji swiftly seized the moment to rush in. Half a second later, they fired a few shots, taking down the criminal, and the hostage fell along with them.

Just as the hostage hit the ground, a round black object suddenly rolled to their feet.

"It's a grenade! Protect the hostage—!"

Gu Ji shouted, eyes wide, and kicked the grenade away, then turned back to shield his teammates.

"Stop!"

At this moment, Zhang Wenjun, observing the battle from the second floor, interjected, and the officers playing the roles of criminal and hostage got up and left the scene, leaving only Gu Ji's group standing in the room.

"Sun Zhibin, your posture before breaking in is incorrect; your whole body is exposed too much. If the criminal hears any noise, they could shoot you through the wooden door. Gao Bo, you need more practice with your steps. Don't walk with crossover steps; how many times have I emphasized this!"

At the end, Zhang Wenjun's stern eyes swept up and down Gu Ji:

"Gu Ji, as the tactical commander, in a confined space, why didn't you remind your team to switch to handguns? Gao Bo's rifle butt obstructed your second entry timing, giving the criminal half a second to push away the hostage and throw the grenade. And why did you kick the grenade away at the end? Don't you know the blast power of a grenade indoors?"

Watching the drill, Wu Kang almost couldn't help but laugh.

For the past few days, Zhang Wenjun had been scolding Gu Ji at every chance in class, and now, once again, he's pinning the blame of this practical training on Gu Ji.

Gu Ji pondered for a moment:

"The instructor is right. I should indeed have considered that. As for kicking the grenade away, I thought it was the best solution at the time. In a narrow space with nowhere to hide, kicking the grenade to as unoccupied a place as possible and using our gear and dodging posture to reduce the fatality risk is the most secure method."

"Then why didn't you dodge, but instead turned to protect your teammates?"

Zhang Wenjun immediately pressed.

Gu Ji hesitated for a moment.

"I... It's instinct, instructor!"

"Instinct? You are the tactical commander, the core of the team. You're the one who should discard all distractions and command the team to save the hostage, not act on impulse to glorify yourself and play the unsung hero!"

Zhang Wenjun reprimanded Gu Ji, word for word.

The other officers found it difficult to listen to this. Was it wrong to protect their comrades?

Everyone suddenly felt a little sorry for Gu Ji. Did he offend Mr. Zhang somehow? Why is he being so harsh on him specifically?

But in the next second, they withdrew their sympathy.

Li Ruilin, watching Gu Ji, suddenly chuckled and spoke:

"Hehehe, Wenjun, I think Gu Ji's spirit of unconditional trust and selfless dedication to his comrades is commendable. His flaws don't overshadow his virtues. Gu Ji, keep working hard next time!"

Well, well.

The esteemed chief instructor of police training and director of the municipal special police force personally encouraged him by name.

What's the story with this guy?

Even Wu Kang couldn't help but take another look at both Gu Ji and Li Ruilin.

"Yes... chief instructor."

Gu Ji scratched his head, pretending not to notice the little expressions exchanged between the two old foxes.

"Alright, that's it for today's class!"

Li Ruilin waved his hand, and the officers cheered and left the scene.

After everyone had left, Zhang Wenjun's tense face buckled, "Mr. Li, it's not easy playing the villain. This kid is progressing too fast; at this rate, I'll soon have nothing to critique."

"This kid indeed has something, not losing to the old Lei back in the day..."

Li Ruilin put away his smile and sighed.

But Zhang Wenjun was surprised to hear this. The old Lei mentioned by Mr. Li was the deputy captain of the Dragon and Tiger Assault Team, the ace of Ningzhou City's special police, and a top national counterterrorism expert!

Thinking of this, a complex expression flickered in his eyes.

Meanwhile.

In Japan, at the Hokkaido City Shinkansen station.

The train doors opened, and passengers poured out. Among the crowd, a long-haired woman in a white T-shirt and black baseball cap was staring at her phone's map, which displayed the name of a clinic: West Street Psychological Clinic!
