"Consultant Lin, how come you even know this? These are my college majors! ”

Xiao Liu studied mineral resources engineering back then.

Although he later went to the oil field, when he was in school, he learned a lot of professional knowledge related to smelting.

He is all too familiar with the "steel filling method".

In the last years of the Eastern Han Dynasty, when the wars continued, the people were struggling to make a living, and they couldn't afford to eat, of course, smelting had to be a little later.

In the period of the Northern and Southern Dynasties, although the north and the south were divided, they could be regarded as having a moment of peace.

The "steel filling method" came into being.

"To put it simply, this process is by heating pig iron and then adding a lot of charcoal to it to increase its carbon content. This not only reduces costs, but also increases production. I don't know if I'm right? ”

Xiao Liu nodded like pounding garlic at this time, and his eyes were full of curiosity and admiration when he looked at Lin Yi.

Wang Qiang also recovered at this time.

"Lao Lin, according to what you mean, these two iron gates were not placed here by devils?"

"Of course not, remember the big spider in the trap before?"

Everyone nodded.

"This thing originally lived in the subtropics, and it shouldn't have been here, but it was here, and it was so much bigger than its normal counterpart."

Speaking of this, Lin Yi set his eyes on his own side.

The other three immediately understood.

They are no strangers to this larger-than-normal animal.

Previously, in the "pyramid pass" of Aoshan, what I saw was much more shocking than this.

"Did Yu Wenrui do it?"

Lin Yi nodded.

"Judging from the casting process and year of these two iron fences, it is different from the iron plates we saw before, except for Yu Wenrui, I really can't think of who else did this."

"But why would he put a mechanism here?"

"This man thinks differently, and why he did it, I can't make up my mind now."

"If you want me to say, this guy must have studied psychology, you guys pondered and pondered, we went smoothly all the way, and we thought it was okay, but he suddenly came to you so suddenly, and we were caught off guard."

"What Lao Wang said makes sense, maybe this is also Yu Wenrui's true thoughts, he must have rebuilt more than this trap here, and he must be up to twelve points of spirit in the future."

The cause of the trap has been analyzed, and the next question is how to get out of it.

"Do you have hydraulic tongs with you?"

Bai Lu asked.

Old Wei shook his head.

"It's all firefighting, we don't have a distribution here."

"Then there is no way, you stand back!"

As he spoke, Lin Yi took out the barrier knife and held it in his hand.

At the beginning of the "Double Zhou Tomb", Li Chunfeng's "Book of Clouds" mentioned that this barrier knife sharpens iron like clay.

I've used it to chop stones and chains before, and it's the first time I've really come up against such a thick iron fence.

Everyone stood behind Lin Yi one after another, only to see him holding a knife in both hands, spotting the connection of the iron fence, and slashing down with all his might.

There was a burst of sparks in front of him, and the junction of the fence was split in two by the barrier.

Looking at the barrier knife again, it was unscathed, and even the edge of the blade was not rolled.

"Good boy, it's really a god, what kind of knife is this?"

When Jin Pengfei saw the scene in front of him, he almost began to doubt his eyes.

Men are born with a special affection for swords, which should be in their genes.

What's more, his profession is a police officer, so he is naturally more sensitive to this kind of sharp weapon, that is, a controlled knife.

Lao Wei didn't say a word, and slapped Jin Pengfei on the back of the head.

"What knife? Which eye did you see the knife? Isn't this a saw? ”

Hearing the master's words, Jin Pengfei immediately reacted.

In order to save everyone from the predicament, Lin Yi had no reservations, and the treasure knives at the bottom of the box were all invited, at this time, some principles were not so important.

"Yes, yes, yes, it's a saw, it's a saw, a good saw. Consultant Lin, you continue! ”

The people present also understood what Lao Wei meant, and smiled knowingly.

Lin Yi cut out a passage with these three knives, and Wang Qiang flew up with a kick and kicked the fence to the ground.

"Let's go!"

Everyone followed this gap and finally escaped smoothly.

"Whew!"

Wang Qiang was the last to get out of the cage, lit a cigarette, and turned around and let out a sigh.

"I'll just say that the path I chose won't be wrong, mainly because Yu Wenrui, this kid, didn't have a good heart."

"Who is this Yu Wenrui you are talking about?"

Wu Jingshan asked curiously.

"How to say it, this person is a strange person, originally a descendant of the Northern Zhou royal family, this was his fiefdom, and later in the early Sui Dynasty, he moved his family to the edge of the desert, and then formed an indissoluble bond with this Tibetan soldier cave.

And this person knows astronomy and geography, and he is also an inventor. ”

"No wonder you can design such an ingenious mechanism."

"Delicate? That's it, in my opinion, if he really wants to kill us, he will place a device that can fire crossbow arrows in this fence that we have encountered before, not to mention us, even the gods will be in danger. ”

Wang Qiang joked.

Goku suddenly became restless.

Jumping up and down on Lin Yi's shoulder, making a squeaky sound.

Everyone suddenly felt that something was wrong, and the stone brick road under their feet seemed to tremble, and the wall made a rumbling sound.

"Oh, I said guys, who has run into any mechanism again?"

Qian Sheng shouted helplessly.

Wang Qiang had a cigarette in his mouth and was stunned on the spot.

"I'm just saying it casually, it's not really going to be fulfilled, is it? What kind of movement is this, it can't be an earthquake, right? ”

"Earthquake?"

Hearing this, a panic suddenly arose in everyone's hearts.

Now they are underground, and in the event of an earthquake, there is a high probability that they will not survive.

"Overhead, look overhead!"

Xiao Liu stretched out his hand and pointed at it tremblingly.

When everyone looked up, their hearts instantly cooled.

The ceiling, which had been nearly six meters high, was now completely out of control, and it fell towards where they were.

The fall was so fast that if they were hit by this large piece of masonry, they would have to turn into meatloaf on the spot.

"Let's go! Come on! ”

Lin Yi shouted, reached out and grabbed the collars of Bai Lu and Wu Jingshan beside him and threw them out.

He himself pulled out the vajra umbrella from behind him, pinpointed the center of gravity of the ceiling, and held up the vajra umbrella, temporarily withstanding the speed of the ceiling's fall.

The diamond umbrella is made of aviation aluminum, which is light in weight, corrosion-resistant, and not afraid of water and fire, but the biggest problem is the lack of rigidity.

At the moment when everyone retreated outward, the handle of the King Kong umbrella was visibly bent with the naked eye.

Lin Yi tried his best to fight against the bend.

"Lao Lin, let's go!"

"You guys go first, don't grind, hurry up!"

Lao Wei and Jin Pengfei had already escaped first, and the two of them answered at the exit, first dragging Bai Lu and Wu Jingshan out, and then pulling Xiao Liu and Qian Sheng out.

Wang Qiang couldn't rest assured that Lin Yi was on his knees, and he didn't forget to hold on to the ceiling with both hands.

Seeing this, Lin Yi kicked Wang Qiang out with a flying sliding shovel.

He took off the flying tiger claw on his waist, threw it out to find the right point of borrowing, and as soon as he closed the lock, the strong pull pulled him out.

Just as his front feet rolled to the ground, the ceiling behind him crashed down, causing a puff of smoke. (End of chapter)
