"Yes, you kid go and watch it by yourself."
Jianguo walked to the table and uncovered the thick red silk. At a glance, he saw a wooden box, a porcelain bottle and a leather bag on the metal tray under the red silk...
Jianguo casually picked up the dark red "color" wooden box that was less than 20 centimeters long, less than 10 centimeters wide, and less than 5 centimeters thick, and put it in his hand...
It was so light, as if there was nothing in the wooden box.
Jianguo glanced suspiciously at the place where he was speaking, and opened the lid of the wooden box...
A small dagger, no more than eighteen centimeters long, no different from ordinary daggers, but a small dagger with pitch black body and no metallic luster...
Jianguo once again looked up at the place where the old man was talking, and put the small dagger in his hand...
Wow, the dagger is so light, as light as it is made of paper.
The anticipation did not sound, Jianguo couldn't help but speak.
"Master, this is the baby you are talking about? Nothing special?"
"This is the treasure that the teacher wants you to see, this is the only dagger on earth that the teacher wants you to see so far..."
"On earth? Unique? Except for light and black, this dagger is no different from ordinary daggers?"
"You must have heard the term "cutting iron like mud", and you must know what kind of substance is diamond. This dagger cuts diamonds more than mud..."
"how can that be?"
Jianguo carefully looked at this small dagger again while "confused". The dagger was very thin and the mouth was unusually sharp, but the dagger didn't have any elasticity...
Well, it’s a bit special, but...
"Master, I have never heard of such a hard thing on the earth. Besides, if this dagger is really so hard, what is it made of?"
"Good question. Disciple, the material used for this dagger doesn't come from the earth. Isn't nature amazing enough? But many phenomena in the world can't be explained by natural science, or can't be explained at all... For example, The invisibility you asked about, such as this dagger, these are all supernatural phenomena... Why do you and I have the invisibility function, let alone the teacher can’t explain it, it is the scientists all over the world who study this problem together and study it for a lifetime, but still can’t explain... The predecessor of the dagger was a meteorite, which was discovered by chance by a teacher. It has been 80 years since I brought it, and it has been studied by scientists for 80 years. However, no one knows the molecular structure of this meteorite and its inner nature. Composition, I only know that this meteorite is surprisingly light, surprisingly hard, light can't be lighter, harder can't be hard... Did you know? In order to build this dagger, a total of eighteen grinders were worn out and completely worn out. Ninety-nine-eighty-one-ton grinding wheel, it took ten years to build this dagger... Disciple, do you think this dagger is a treasure?"
