Just when Kangxi was slandering, it was time for the prince's gift, the prince's reading notes, the boss's military strategy, the third child's calligraphy and painting, and the fourth child's Buddhist scriptures......

Soon it was time for the Ninth Elder Brother.

Brother Jiu ordered someone to carry a stone slab up and said, "Khan Ama, the retainers offer a piece of cement slate." ”

The hall suddenly fell silent, and one by one they craned their necks to stare at the piece that was carried up by the minions...... Flagstone?

"I'll go! It's really a slate! Someone muttered something quietly.

"Well, there must be another mystery on this stone slab." Someone whispered a word right away.

Another person approached and said, "Maybe there is some precious ancient inscription on it?" I can't see it clearly from this distance. ”

At this time, Kangxi asked curiously: "This piece of water ...... Cement slate? It's called cement slate, right? Is there anything unique about it? ”

Brother Jiu said: "Hui Khan Ama dialect, it is called cement slate, if you insist on saying that it has any unique features, it is made by the sons themselves, does this count?" ”

The third elder brother smiled slightly: "The ninth brother made a stone slab with his own hands? This gift...... Well, it's chic. ”

said chic, but the tone of the third elder brother was not like that at all.

The Ninth Elder Brother glanced at the Third Elder Brother lightly and said, "This stone slab is indeed unique, because it is made of water, river sand, mud and gravel. ”

The smile on the third elder brother's face instantly froze: "Water, river sand, mud and gravel? How can these things become such a slate? Ninth brother, don't lie in front of Khan Amma, this is a crime of deception! ”

The third elder brother has never heard that dirt, river sand, gravel and water can be turned into hard slates, isn't this a joke?

Everyone's eyes fell on Kangxi, wanting to see what his expression was.

However, Kangxi held a face, and there was no expression on his face.

Brother Jiu said lightly: "The soil can be burned into ceramics, and the river sand can be burned into glass, why can't these things be turned into stone slabs?" ”

Everyone was stunned for a moment, what Brother Jiu said made sense.

The third elder brother said unconvinced: "Ceramics and glass are fragile, but they are beautiful in appearance and can be used as utensils, what is the use of your slate?" It's so ugly. ”

Brother Jiu smiled: "Although my slate is ugly, it is hard!" ”

"It can't be!"

The third elder brother didn't believe it at all, how hard could the things made out of the river sand and mud be?

Brother Jiu stretched out his hand and pointed: "If the third brother doesn't believe it, you can give it a try." ”

The third elder brother looked at Kangxi, hugged his fists and said, "Khan Ama, Erchen asks for a try." ”

Kangxi nodded, and the third elder brother called two guards to lift the stone slab: "Hit the master hard!" ”

He didn't believe it, and he couldn't break it!

The two guards lifted the slate and threw it down hard, with a muffled sound, and the slate ...... Safe and sound.

The third elder brother rubbed his eyes and hurriedly said, "This slate is so thick, it's normal to resist falling at all, Khan Ama, my son asked to try it with a hammer." ”

Kangxi agreed again.

After a while, a guard brought a hammer, and after asking Kangxi, he raised the hammer high, and then smashed it down!

There was a muffled sound, and everyone looked intently, only to see that the slate did not move at all, and only a little white mark appeared on the face.

The eldest brother was interested, pushed the guard away, took the hammer, and said, "Come and try." ”
