That's amazing survival skills!

Li Wen smiled. "Brother Lin, would you mind if we looked for it together?"

"Of course, this factory isn't owned by my family." Lin Yuan stretched out his hand and said with a smile, "Many hands make light work."

"it is good."

The two teams dispersed and rushed to other factory buildings, imitating Lin Yuan and his group by tapping left and right, and lying down to listen carefully to the echoes.

"Aren't you afraid that they'll find it and won't tell you?" Gu Siyu whispered a reminder.

The factory area is very large, with many workshops. With only the four of them, it would take them an unknown amount of time, not to mention the time required for manufacturing. With more people, things can be done much faster.

"It's no big deal," Lin Yuan said with a smile.

He had his own considerations.

Although I didn't study mechanical engineering before, I've never eaten pork, but I've seen pigs run.

Something of that strength must have been made with considerable noise during its manufacturing process; even with appropriate sound-absorbing materials, the noise would still be audible.

"It's good that you have your own plans."

Seeing the indifference on Lin Yuan's face, Gu Siyu understood that the other party had his own ulterior motives, so she wasn't too worried. She turned around and walked out of the factory, starting to explore her surroundings.

Half an hour later.

Lin Yuan stepped on the factory floor tiles, and the sound that came back was still solid, not the kind of hollow echo.

"Where exactly is it?"

Just as Lin Yuan was still wondering whether it was hidden somewhere else or could only be found by opening a box, a red dot appeared in the message panel in the lower right corner.

[Han Miao: Found it, come quick!]

At the same time, there is an invitation below the signature in the chat box.

[Should we join the location patrol?]

"Yes."

Upon entering, Lin Yuan found that his location was a small red dot, and there was another small red dot in the distance on the pattern. The other side displayed a large "end" character, while his displayed the "beginning" character.

Suddenly, two red dots appeared on the pattern, both displaying the character "起" (qi).

Lin Yuan walked towards the finish line on the chart, his gaze falling on the pattern, and noticed a red dot with the character "起" (qi, meaning "start") not far ahead.

Passing through the factory, they found it was Wang Xi, accompanied by Hu Zi and two other teammates from Li Wen's team.

Lin Yuan nodded to the others in greeting, then took Wang Xi's hand and continued heading towards Han Miao's direction.

When her hand was grasped by that large, warm, and strong hand, Wang Xi felt a surge of panic. She tried to break free and say that she could walk on her own and didn't need a guide!

But there were other teams behind them, and in the end, they didn't take any action.

Hmph! I'll give you some face!

After turning the corner, Li Wen and his men arrived. They nodded to each other and continued walking forward.

The outermost perimeter of the factory building.

The building materials used to construct this factory are clearly different.

Li Wen and Han Miao were standing at the door. They were not far apart. After Li Wen noticed, she quickly told Han Miao to call Lin Yuan over.

Han Miao sent the message but did not rush in; she knew her own limitations.

"There's nothing inside." Han Miao pointed to the empty factory building, but the floorboards were hollow, and stepping on them made a hollow thumping sound.

Everyone entered the factory.

Sure enough, there was nothing inside. There were no pipes or switches on the walls, just like an empty room.

Lin Yuan took two steps forward and discovered that the empty space below was not just one place, but more than one after measuring it with his feet.

The bottom is completely empty!

"There's something down there." Li Wen also used his feet to measure the area, scanning the surrounding smooth walls. There were no switches or switches. "How do we get this thing out?"

There's an old saying: "Strength can overcome skill!"

Li Wen, wielding an elite iron axe, and Lin Yuan, holding an elite spear, began to dig into the metal ground.

Clang! Bang!

The weapon that could easily destroy the metal shield under Liang Jing's puppet could only leave scratches on the ground.

"Damn it, this floor is too hard!" Li Wen carefully examined his axe and breathed a sigh of relief when he found that there were no chips or nicks.

The axe in their hands is now considered their team's most powerful trump card.

I feel terrible if it gets even the slightest damage.

Lin Yuan had no choice but to put away his spear, put his hands behind his back, and walk outside. "I'll go see if there are any other traps around here."

"OK."

Avoiding everyone's gaze, Lin Yuan walked to the back of the factory, took out his Eye of Truth, and scanned the factory back and forth.

The scenery before my eyes changed.

The ground around the factory became transparent, except for a blue light and shadow on the entrance wall.

【911】

"Damn, they hid it really well." Lin Yuan put away his Eye of Truth and returned to the factory.

"How's it going? Any discoveries?"

"I didn't find anything, but there must be some kind of switch here, otherwise, given the strength of the metal underfoot, it would break every time it's used, and the cost would be too high." Lin Yuan shook his head and looked at the smooth metal walls around him. "We'll just have to use the old method: feel around."

As he spoke, he began to feel around on the wall, tapping lightly and listening to the echoes.

Li Wen was speechless when he saw his expression.

But having come this far, it would be somewhat unbearable to give up, so I had no choice but to follow his example and start taking action.

Although this method is inefficient and outdated, it's the only option left now.

Lin Yuan tapped along the metal wall as he approached the entrance.

Thump, thump thump.

"The sound here is different!"

His words drew everyone's attention.

Lin Yuan's hand groped and slid up and down on the wall.

Click!

A slight sound was heard as the sleek metal wall was pushed open, revealing the activation machine hidden underneath, which could be verified by fingerprint, iris, and keypad combination lock.

"We can't do anything with iris or fingerprints, so we're left with only the password." Li Wen clicked to turn on the phone.

Please enter a four-digit password.

Gu Siyu looked at the number buttons from 1 to 9 and couldn't help but pinch her brow, pretending to be extremely troubled. In reality, she believed that Lin Yuan already knew the password.

Otherwise, why would he start feeling around the metal wall after just one trip outside?

But the performance is still very necessary!

The woman looked at the numbers on the screen and said, "Let's not do it anymore, there's simply not enough time."

This kind of combination of numbers can result in a terrifying number of combinations. Trying them one by one, even without a protection period, would take months.

"I'm still a little unwilling." Li Wen gritted his teeth, the fine axe falling back into his palm. "Brother Lin, step aside, let me chop it open with one swing of my axe, and see if I can open this damn mechanism by short-circuiting it."

Damn it, you brute!

Lin Yuan quickly stopped this guy who only relied on brute force, unaware that his previous behavior was no different.

"Let's try the password first. If that doesn't work, it's still a viable option," Lin Yuan advised.

Even though we already know the password, we can't just use brute force at this crucial moment. If it gets broken and we can't activate it, then all our efforts will be in vain!

Lin Yuan pretended to type in several four-character keys, but all of them indicated that the password was incorrect.

You have one last chance; you have five minutes to save time if you make a mistake.

"Brother Lin, don't waste time. Let's use my method." Li Wen stepped forward, raising his axe. "My method will solve the problem once and for all!"

"Wait, let me think about it some more."

Lin Yuan paced back and forth in front of the cipher machine with his hands behind his back, his eyes constantly scanning the empty space in front of him.

Seeing the irritation Lin Yuan displayed, Gu Siyu couldn't help but praise him in her heart, thinking that he was actually quite capable.

Wang Xi also looked at Lin Yuan.

If it weren't for the inappropriate occasion, she would have rolled her eyes long ago.

Do you really think she's stupid?

"That's right!" Lin Yuan strode forward, quickly pressed 911, and then stopped.

Please enter the last digit.

Seeing that Lin Yuan had withdrawn his finger and hadn't pressed the last number, leaving only 911 displayed, Li Wen asked, "Brother Lin, why did you stop?"

"I just remembered something interesting," Lin Yuan said with a smile, pointing to the cipher machine. "Since this is the last chance we have, I might as well indulge my morbid curiosity."

Li Wen: "..."

However, he said he didn't mind, since it was just like letting him mess around for once.

[Didi, verification successful.]

Li Wen's eyes widened, somewhat unable to believe his ears.

Wasn't it supposed to be a four-digit password?

What's going on with these three digits?!
