Cao Cao called me to rob a tomb

Chapter 335 "Curie Point" (4000)

"Suck..."

Yu Ji's words reminded Wu Liang.

The metal block of the "mechanical seal" will be closed immediately after being pushed away by them, and the chisel in Bai Jingjing's hand feels like it will be taken away by the "mechanical seal". Isn't this strange force the "suction force"?

If it is "suction"...

Wu Liang suddenly thought of a possibility, could it be "magnetism"?
What kind of metal this "mechanical seal" is made of, Wu Liang still doesn't know, but the chisel Wu Liang is very clear, it must be mainly iron.

Because I have seen many such chisels in the cave before, and these chisels have more or less rusted on them.

That kind of reddish-brown rust, even if Wu Liang had no common sense, he knew it was rust.

And the magnetic force just can generate attraction to iron products.

That's why Bai Jingjing felt a strange force trying to take the chisel away from her hand?

At the same time, it is different from Wu Liang.

Yu Ji's words immediately made everyone more nervous.

He has almost concluded that some kind of terrible mutation has taken place in the corpse in this "mechanical seal", and it is because of this mutation that everyone can't open the "mechanical seal" now.

In this way, everyone is a little more afraid of the things in this "mechanism seal".

So at this moment, all eyes are on Wu Liang, hoping that he can make a decision.

Facing everyone's eyes, Wu Liang did not respond positively to Ji, but said to him: "Mr., please take out the compass I improved for you."

"What is the meaning of this, son?"

Yu Ji suddenly looked puzzled.

What time is it now, is it necessary to explore the terrain and direction here?

What's more, if you want to study feng shui, the old man has read it carefully before and explained it in detail. There is nothing extraordinary here, and it is not a poor mountain. How can there be any need to read it again?

"If you are told to take it, you will take it."

Wu Liang said without a doubt.

Naturally, Yu Ji didn't dare to say anything more, and quickly took out the compass from his small cloth bag, and then presented it to Wu Liang with both hands.

Wu Liang took the compass, glanced at the simple compass installed in the center of the compass, and saw that the compass was indeed pointing in the direction of the "machine seal".

"You said, is this true north?"

Wu Liang pointed to the "Ji Feng" and raised his head to ask.

"..."

Everyone looked at each other in blank dismay, then shook their heads slightly.

After entering the dark cave, without any reference, they actually lost their way.

However, there is only one path leading directly to the underground palace, so the direction is not so important, so naturally no one cares about this issue.

In fact, the same is true for Wu Liang, he doesn't know the north, south, east, and west now.

However, he asked Yu Ji to take out the compass, not to distinguish the north from the south, but to confirm his own judgment.

then.

He immediately circled the "mechanical seal" with the compass again.

After turning around in this circle, things became more and more clear, because the north needle on the compass was also constantly changing direction as he walked.

And the direction it points to is always this "mechanism seal".

It can be seen from this that the compass has completely lost its function of indicating direction when it reaches this place.

The working principle of the compass is magnetism.

The answer is already on the horizon.

Wu Liang was determined, and then said to Dian Wei: "Brother Dian Wei, throw your engineering shovels at the 'Ji Feng'."

"promise."

Although he still didn't understand what Wu Liang meant, Dian Wei was still the prefect and threw the sapper over.

"Chong!"

With a crisp sound, a miraculous scene appeared.

Not only did the engineer shovel not bounce off, nor did it fall off, but it stuck to the hard and smooth "machine seal" like brown sugar.

Sure enough, it is magnetic!
Wu Liang may not be completely sure about other things, but the shovel heads of the Huren Army's engineers are definitely made of fine iron, and no one can adulterate them.

Just now, Wu Liang touched the "mechanical seal" with the wooden handle with the shovel head removed and only a "love menstrual scarf" tied on it.

At that time, the "machine seal" did not suck Wu Liang's wooden handle.

"?!"

When everyone saw this, their hearts tightened again.

Just now Yu Jigang said the rumors of "corpse breath sucking the coffin", but now this "mechanical seal" can firmly suck the engineer shovel, which is too frightening.

It's not that they don't know much.

The main reason is that although the natural magnetite has been discovered in this era, it is called "the kindness stone", and the magnetic force of the kindness stone has been known to some extent, but the specific principle is still only half-understood, and the reason why the magnetite is called "the kindness stone" "Benevolence stone", it is also said that this is a kind of stone with a heart of love. Only a stone of kindness can attract iron objects. This kind of explanation is a bit mysterious.

And for the vast majority of ordinary people, they will never have the chance to see a magnet in their entire life, so it is reasonable to not know much about it.

"Don't panic. I suspect that this is not caused by corpse aura, but by magnetism. The material used to build this 'mechanism seal' is probably not ordinary metal, and there is also a part of 'kindness stone', so it can attract iron objects."

Wu Liang finally expressed his conclusions in a way that is relatively easy for everyone to understand, "If you don't believe me, you can try something other than iron, this 'mechanical seal' will definitely not be able to produce weird power anymore."

"Brother talented, what you said is true?"

Zhuge Liang actually had a bit of tiger spirit like a newborn calf not afraid of tigers, after hearing Wu Liang's words, he actually picked up a stone from the ground and threw it at the "Ji Feng".

"Snapped!"

When the stone hit the "machine seal", it was not firmly sucked like an engineer shovel, but bounced to the side and fell to the ground.

"It's true!"

Seeing this situation, Zhuge Liang immediately relaxed, and even showed his stinky face to Huang Yueying who was behind him, "What am I talking about, my talented brother is not an ordinary person, he knows a lot, and now I follow him." The talented brother has been impressed by his ears and eyes, and he will definitely become a general in the future."

"..."

Everyone also breathed a sigh of relief.

In fact, they also had a little understanding of "Ci Shi". When the wooden armor man was found in Qi Aigong's coffin, Wu Liang found some powders of different colors from his body.

Those powders contain part of the "compassion stone" ingredients, which are currently being researched in Thyme.

Even the compass installed on Yu Ji's compass, the pointer on it was made by Wu Liang with some magnetic powder.

It's just that they really didn't expect that someone would use the "stone of kindness" to create such a large "mechanism seal", and the suction of the "stone of kindness" could be so strong, even to the point of stealing a weapon.

This is really an exaggeration.

"Your Excellency is really well-informed, and you can make such a judgment."

Sun Ye obviously knew something about the "stone of kindness", and said with admiration, "I am also amazed at the ability of the patriarch, who would have thought of using such a mysterious 'stone of kindness' to build a 'machine seal', so as to achieve purpose of protection from intrusion."

"What I personally admire is that the patriarch was able to find such a large 'kindness stone'. If he hadn't discovered the 'kindness stone mine' and had a clear understanding of the characteristics of the 'kindness stone', I'm afraid it would have been impossible anyway. It is impossible to build such a large and magnetic 'seal'."

Wu Liang nodded.

These days, no one has been able to create artificial magnets, and no one has been able to use electricity to create magnetism. The only source of philanthropic stones is the natural magnetite from the philanthropy mine.

And all those excavated from the Cishi Mine are permanent magnets that will never be demagnetized.

Let alone hundreds of years, even thousands of years, if there is no unexpected situation, it will still work.

Besides.

What's even more commendable is that Lu Ban was able to make these magnetic metal blocks into such a shape, and combined them into a tightly fitting cuboid.

It is necessary to know that because of the magnetic properties of compassion stones, each piece has positive and negative poles.

Anyone who has studied in the future knows that the positive and negative poles have the characteristic of "opposites attract, same sex repel".

Even if it is said that it is not an easy task to combine these magnetic compassion stones together to form a whole.

Basically, every contact surface of each kindness stone must meet the characteristics of "opposites attract", and the positive and negative conditions of other kindness stones that are directly produced must also be considered...

This is easier said than done.

But as far as Wu Liang knows, only in the Western Han Dynasty did people gradually study this characteristic of Cishi in historical records, and there were no relevant records in the Spring and Autumn and Warring States periods hundreds of years ago.

And with this discovery.

Can it be said that as early as the Spring and Autumn Period and the Warring States Period, Lu Ban had actually studied and understood this characteristic of Cishi, so he was able to create such a "mechanical seal".

It's just that for some reason, no corresponding inheritance and documents have been left behind, and the archaeological world in later generations has no way of discovering it.

"This must be recorded and engraved in my biography."

Wu Liang secretly kept this thought in his heart.

Archeology itself is to unravel the truth of history, but because of the loss of some inheritance and documents, later generations often underestimate the ability and wisdom of the ancients.

It’s not that there are many things, it’s just that later generations haven’t discovered them yet…

"My lord, if this 'mechanism seal' is made by Cishi, I'm afraid it can't be opened by ordinary means?"

Yu Ji stepped forward again, and asked worriedly, "Just now you and Dian Wei and Yang Wanli still pushed it still, even if you opened a gap, as soon as you let go, it will close immediately, although it has been inserted now A chisel goes in to prop up the gap, but even if the gap is pried a little wider, the result is the same, as long as the kindness stone cannot lose its suction, the 'mechanical seal' may still not be able to be opened."

"You don't know something. Knowing that this is Cishi, it will be much easier to deal with."

Wu Liang laughed with confidence.

"Oh?"

Yu Ji hurriedly asked, "What can you do, Young Master?"

"?"

Sun Ye also unconsciously looked over, his only remaining eye was full of curiosity.

Everyone is already like this.

Even those who know a little bit about the kind stone among them are deeply impressed by "the stone is the mother of iron, but there are two kinds of stones: kind and unkind. A kind stone can attract his children, but an unkind stone cannot." Argumentative influences like this.

And Wu Liang said that the attraction of this matter can be easily eliminated, which is equivalent to eliminating the anthropomorphic "love" in the kindness stone, which is more or less mysterious.

"Old man, Yang Wanli, take out the kerosene we are carrying."

Wu Liang didn't answer, but said to Yu Ji and Yang Wanli again.

Although Wu Liang had Suihou beads as a lighting tool, he always asked several members of the backbone of the Huan army to carry a few small pots of fire oil for emergencies. Even if they needed to split up, they could still make torches.

"okay."

The two of them hurriedly followed suit.

Then Wu Liang looked at Sun Ye again, and said with a smile, "Mr. Sun, shall we discuss something?"

"Your Excellency, please speak."

Sun Ye was taken aback for a moment, but also said hastily.

"The vertical burial coffin over there that is suspected to be your ancestor's coffin, if you don't mind, I think it should be fine if you chop it up and use it as firewood, right?"

Wu Liang pointed to the empty coffin engraved with the words "Yuwenji" and said.

"This……"

Sun Ye glanced back at the coffin. Although he was a little reluctant in his heart, mainly because he didn't want Wu Liang to mess with Gongshuzhong, but in the end, curiosity prevailed in his heart, and he couldn't help but nodded and said, "It's just an empty coffin. , Your Excellency will be destroyed if you destroy it, it doesn’t matter, but please remember your previous promise, don’t wantonly destroy the Gongshu Tomb.”

"It's natural."

Wu Liang nodded slightly, and finally ordered to Dian Wei and Yang Wanli, "You two go, split that coffin into firewood, place it around the 'machine seal', and then sprinkle kerosene on it."

"Your Excellency, are you going to burn the 'seal' of the Patriarch?!"

After hearing this, Sun Ye finally realized what was going on, and asked in surprise.

"Don't worry, with this little firepower, how can I burn down the 'machine seal' made of metal? I just want to warm the 'machine seal' and dispel the suction of Cishi by the way."

Wu Liang pressed Sun Ye's shoulder and smiled.

"In this way, can the love attraction of the kindness stone be dispelled?"

Of course, Sun Ye didn't believe that things could be so simple.

"Of course not, I still need to use some mana to do a ritual that is not humane."

Wu Liang decisively lied.

In fact, it is really as simple as heating.

This is about the "Curie point" discovered by Mrs. Curie in later generations.

This is a physical characteristic of the magnet. When the magnet is heated to a certain temperature, the magnetic force in the magnet will disappear completely.

This temperature depends on the material, density, magnetic force and other factors of the magnet itself.

And even if it is not heated to the "Curie point" in the end, during the heating process, the metal lattice thermal movement will occur inside the magnet, which will affect and reduce the magnetic force of the magnet.

Wu Liang has a general understanding of this.

The "Curie point" of most natural magnets is actually only one or two hundred degrees, and it is easy to reach such a temperature by burning a pile of firewood, and it will never burn the "mechanical seal" to deformation, or it will be separated from the other. With such a thick layer of magnets, the contents of the "mechanical seal" were burned.
