Ronald and Nicole pass through three watertight doors in a row.

After nearly 100 meters in a straight line, they were quite far from where they had come down from the beginning.

So, after properly closing the third watertight door.

Ronald sensed the movement of the people above him, so he said to Nicole:

"Nicole, we're at the bottom of the stern now, and the propellers that power the entire ship are not far ahead."

Nicole has no psychological pressure on this, and there is only the word confidence in her eyes.

"The guidance provided by the spell means that he is going this way, and I think my spell is quite accurate."

That's Nicole's job as an investigator.

So Ronald didn't interfere much, just nodded his head in understanding:

"Then listen to you."

Continuing to follow the spell's tracking, the two of them went up the ladder behind the third watertight door, and turned around to another safety door.

Nicole stepped forward and her eyebrows furrowed—she didn't open the security door.

"It's a little hard to pull away."

Muttered quietly, and Nicole exerted force in her hand.

This time there was a 'pop' sound, and the security door in front of them was opened.

In the rear, a wave of heat rushed directly into the faces of the two people, it was not that the murderer was casting a spell attack in the back, but the air in the rear was already higher than here.

Ronald explained to Nicole appropriately:

"Up front is the cabin area, and the temperature is very high."

"At the same time, because of the difference in air pressure inside and outside, it seems that this door is more difficult to open."

Nicole immediately threw a surprised look at Ronald.

"Ronald, how do you know everything?"

"This kind of ship has only been built and put into use in recent years, and I and even many old sailors don't know about these things, do they?"

In this world, of course, Ronald has never seen these things, this is all the knowledge he has accumulated in his previous life.

So in the face of Nicole's surprise, he only smiled slightly:

"You usually read more books, and after you understand the principle, you will naturally know it."

"Spare me." Nicole immediately gave up her curiosity, "In order to revitalize the school, the only time I have to work is to fish and study spells. If you add reading to that, it's really terrible. ”

Continuing inward, the sound coming from the cabin gradually became louder.

It's the world beneath the ships, where the huge steam engines run, and where the workers work day and night. Combined with the loud sound of the engine operation, the whole environment is like a steel cave in another world.

But for this kind of scene, Ronald and Nicole quite like it.

They had just walked in a deserted tunnel, but now they had entered the human world, and the light of the fire and electric lights seemed much more comfortable.

"Two, this is the work area, you can't enter it at will!"

At this time, a young man wearing only a 'rag' came running up and reminded Ronald and Nicole:

"Ordinary people don't know the rules here, and it's very dangerous to walk around, and it may even cause problems for the whole ship to follow!"

Facing this young man, Nicole was a little silent for a while.

The other party did not recognize her identity as an investigator, only that the two of them were passengers who came here out of curiosity.

The world placed above the deck.

This is absolutely impossible to happen.

Not only does this place look completely different from the outside, but even the essence of it is really like two worlds!

"Lyman, get to work!"

Just as Nicole was silent, a voice rang out.

Turning his head, he saw a middle-aged man who was dressed equally lightly, but was much more elaborate than the others.

"They're not the ones you think, leave them to me."

"Yes, Mr. Orr!"

Sending away this dazed and ignorant young man, this middle-aged man stepped forward to introduce himself:

"Two adults, I'm Orr, the chief engineer of this ship."

"Is there anything you have done here?"

The chief engineer is the chief technical officer of a ship, and the captain manages the world on the deck and the world in the engine room, which is definitely one of the top levels of power on the entire ship.

So in the face of Orr's self-introduction, Nicole also put on a correct posture, and then told her intention:

"Mr. Chief Engineer, it's like this—"

"There was a homicide in the cabin just now, and we followed the murderer's trail all the way here."

"Homicide? The murderer is here? The chief engineer's expression was obviously unbelieving, "Our management here is very strict, and it is impossible for any outsider to get in!" ”

"Please let us check." In the face of the chief engineer's negation, Nicole did not back down, and even took the initiative to step forward, "I promise that it will not affect your work." ”

"Now, get out of the way."

As the real power figure on the ship, the chief engineer subconsciously refused the little girl's request.

But he was the chief engineer after all.

His eyes swept over Nicole in front of him, and when he saw the brooch that symbolized the ace investigator, the rejection in the chief engineer's eyes disappeared.

He immediately leaned sideways to get out of the way, and at the same time said:

"In that case, please let me follow."

"I'm familiar with everything about the cabin, and I can help you with your work."

Seeing the change in the chief engineer's attitude, Nicole naturally nodded and replied:

"Then please."

Next, Ronald and the chief engineer followed Nicole in the engine room.

Instead of going to the main shaft room where the propeller was mounted, they were led by the spell and advanced all the way to where the steam turbine was. Hundreds of coal furnaces work around the clock to power the ship's core.

So as soon as they arrived, the chief engineer spoke:

"Miss Investigator, this is one of the most important places in the cabin, and at the same time the most tightly managed."

"I know you take murder very seriously, but there's really no way there's a murderer here."

Nicole shook her head at the chief engineer with a serious face.

Then she pointed to a hard-working, sweaty worker in front of her, and then said to Ronald next to her:

"That's him, Ronald."

"Your spell is suitable for catching people, help."

Ronald has no objection to this.

Because in his emotional perception system, this worker is really not quite right. It's just that Nicole is the one who leads the arrest work, so he didn't take action immediately.

At this time, Nicole opened his mouth like this, of course, he directly reached out and made a move.

Brush –

Thin workers flew upside down.

He was completely unable to resist Ronald's spells, like a quail being picked up by Ronald.

Then he looked at Ronald, the guy who grabbed him, the guy with a dirty face, and showed a flattering smile:

"It turned out to be you, I thought it was who, it scared me just now!"

"Mr. Ronald, we are our own people!"
