However, as far as Wu Liang knows, historical records indicate that it was only during the Western Han Dynasty that someone gradually discovered this characteristic of Ci Shi. However, there were no relevant records in this regard during the Spring and Autumn and Warring States periods hundreds of years ago.

And with this discovery.

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

It's just that for some reasons, no corresponding inheritance and documents were left, and later archeology has no way of discovering it.

"This matter must be recorded and engraved into my biography."

Wu Liang secretly kept this idea in his mind.

Archeology itself is to uncover the historical truth, but due to the loss of some inheritance and documents, later generations often underestimate the ability and wisdom of the ancients.

It’s not that a lot of things don’t exist, it’s just that later generations haven’t discovered them yet…

"Sir, if this 'mechanical seal' is made by Ci Shi, I'm afraid it can't be opened by ordinary means, right?"

Yu Ji stepped forward again and asked with some worry, "Just now you, Dian Wei and Yang Wanli still pushed it and it wouldn't move. Even if you push it open a gap, it will close immediately as soon as you let go. Now, although it has been inserted

A chisel goes in to prop up the gap, but even if the gap is made wider, the result will be the same. As long as the stone cannot lose its suction, the 'mechanical seal' may still be unable to be opened."

"You don't know something. If you understand that this is Ci Shi, it will be much easier to deal with it."

Wu Liang laughed confidently.

"oh?"

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

"?"

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

This is already the case with everyone.

Even those who know a little about loving stones are convinced that "stone is the mother of iron, but there are two types of stones: loving and unkind. A loving stone can attract his children, but an unkind stone cannot."

Such arguments influence.

And Wu Liang said that being able to easily eliminate the suction force of this matter is equivalent to eliminating the anthropomorphic "love" in the Ci Stone. This is more or less mysterious.

"Old sir, Yang Wanli, take out the kerosene we carry."

Wu Liang did not answer, but spoke to Ji and Yang Wanli again.

Although Wu Liang had Suihou beads as lighting tools, he would always ask a few of the backbone of the Hu army to carry a few small pots of kerosene in case of emergency. Even if they needed to split up, they could still make torches.

"okay."

The two of them quickly followed the instructions.

Then Wu Liang looked at Sun Ye and said with a smile: "Mr. Sun, let's discuss something?"

"Your Excellency, please speak."

Sun Ye was stunned and said quickly.

"The vertical burial coffin over there is suspected to be the coffin of your ancestor. If you don't mind, I think it should be fine to chop it into pieces and burn it as firewood, right?"

Wu Liang pointed to the empty coffin with the three characters "Yu Wenji" engraved on it and said.

"this……"

Sun Ye looked back at the coffin. Although he was a little reluctant, mainly because he didn't want Wu Liang to mess with the public tomb, in the end the curiosity in his heart took over. He couldn't help but nodded and said, "It's just an empty coffin."

"If you destroy it, it will be destroyed. It doesn't matter. I just ask you to remember your previous promise and not to destroy the public tomb."

"It's natural."

Wu Liang nodded slightly, and finally ordered to Dian Wei and Yang Wanli, "Go ahead, chop the coffin into firewood, place it in a circle around the 'mechanical seal', and then sprinkle kerosene on it."

"Your Majesty, are you going to burn the Grandmaster's 'mechanical seal'?!"

After hearing this, Sun Ye finally realized something and asked quickly in surprise.

"Don't worry, this little firepower can't burn down the metal 'mechanical seal'. I just want to warm the 'mechanical seal' and dispel the suction power of Ci Shi."

Wu Liang held Sun Ye's shoulders and smiled.

"In this way, can the loving attraction of Ci Shi be dispelled?"

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

"Of course it won't work. I still need to use some magic power to do a ritual that is not humane to outsiders."

Wu Liang lied decisively.

In fact, it is as simple as heating.

This brings us to the "Curie point" discovered by later generations of Marie Curie.

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

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

Even if it is not heated to the "Curie point" in the end, during the heating process, thermal movement of the metal lattice will occur inside the magnet, thus affecting and reducing the magnet's magnetic force.

Wu Liang has a general understanding of this.

The "Curie point" of most natural magnets is actually only one or two hundred degrees. Burning a pile of firewood can easily reach such a temperature, and it will never burn the "mechanical seal" to the point of deformation or insulation.
