After the stone was put down, Chen Ping explained to Li Si and the other two: "This stone belongs to the same category as the strange stone in the mountains. I just need to untie the stone, you will know at a glance."

Hearing this, Dun Lie and Mo Xun stepped forward to check the stone and found that the stone was indeed somewhat similar to the strange stones in the mountains.

But this is a coincidence.

Could it be that the strange rocks in the mountains are the ones that young people make?

Thinking of this, Dunruo and Mo Xun looked at each other and asked in a deep voice: "You said the stone that the Langya merchant gave you, but for no reason, why did he give you stone?"

“It’s not without reason.”

Chen Ping shook his head and smiled and said, "It's better to exchange goods for goods than to give it to him. He was hungry, so I gave him two rough steamed buns, and he gave me two strange stones."

"Then why did he carry stones?"

Mo Xun frowned and asked.

Chen Ping replied seriously: "Because he is a businessman who sells strange stones, if Shangguan doesn't believe it, he can send someone to investigate. He is not the only businessman in Langya County."

When looking for stones, Wu Cheng had already solved the problem of the source of the stones, so he was not afraid of them pursuing them.

But Li Si, who was sitting in the main hall, was obviously impatient, so he waved: "Two, time is tight, why bother considering these small matters?"

"this……"

Hearing this, Dunruo and Mo Xun looked at each other, and both saw the word "helplessness" in each other's eyes.

Li Si is impatient and looks at big problems, and he doesn't want to use his brain at all for small problems.

This is not a secret in the court, so the two had to give up asking questions and sit back on their original positions.

"Okay, it's time to start."

Li Si glanced at Lie and Mo Xun, raised his hand to Chen Ping to signal.

Chen Ping breathed a sigh of relief, then pointed to the stone and explained: "The stone in the mountain, after I carefully considered it, is actually flint. Unlike other flints, it comes from the bottom of the sea."

"seabed?"

Li Si tilted his head and asked in confusion: "Since it is on the bottom of the sea, how can it appear in the mountains?"

"Back to Shangguan, it was originally in Linhai Rock Beach, and it should have been secretly transported to the mountains."

"How did the stones at the bottom of the sea reach the stone beach?"

Li Si asked curiously: "Is it because someone deliberately salvages it?"

Chen Ping replied: "The moon has phases and waxing, and the sea has tides. The flint should have been washed ashore by the tide."

"tidal?"

Li Si frowned and then asked, "Is this what you saw with your own eyes, or is the businessman telling you?"

"It was the first time Xiaomin left his hometown, so he naturally listened to the businessman."

Hearing this, Li Si felt that Chen Ping was still sincere, so he didn't delve into it, so he raised his hand to signal him to continue.

"The reason why the seabed chert is different from land chert is that there is a layer of stone shell on the surface of the seabed chert. As long as you pour some green alum oil on the stone shell, it will break the shell and bloom."

"Green alum oil?"

Mo Xun tilted his head, feeling a little puzzled: "Didn't you say that rain erodes?"

Hearing this, Chen Ping immediately replied: "It takes a long time for rain to erode. If you want to break the shell and bloom in a short time, you can only use green alum oil."

Green alum oil is a dilute sulfuric acid produced by those alchemy elixirs.

In ancient times, it was often used to remove rust from weapons.

The flowering of stones is actually the calcium carbonate on the surface of flint tuberculosis. The original appearance of the nodule is dissolved after acid rain corrosion, and the shape of a flower is like a flower.

Zhao Kun saw such stones in his previous life, and it seemed to be available in Guangxi and Shandong, so he asked Wu Cheng to look for them.

Although some people know about the stones in the local area, communication was not developed in ancient times, so most people don’t know about it.

It is precisely for this reason that Zhao Kun used strange rocks to lay out strange phenomena.

"You mean, someone poured green alum oil on the stone, which caused the stone to bloom overnight?" Mo Xun asked suddenly.

"Although I didn't get close to the stone in the mountains, I think it shouldn't be bad." Chen Ping replied.

Li Si glanced at Mo Xun, then asked Chen Ping, "Can your stone bloom?"

"able."

Chen Ping nodded, then took out a piece of bamboo tube from his arms, pulled open the plug, and slowly fell on the stone.

I saw the stones swaying in light smoke, making a sizzling sound.

Dunruo and Mo Xun stood up again, staring at the stone without blinking.

Until the green alum oil in the bamboo tube was poured out, about a quarter of an hour later, cracks began to appear on the shell on the surface of the stone.

Immediately afterwards, a bulge similar to a flower petal was revealed.

"this……"

Mo Xun was shocked and subconsciously looked at Chen Ping.

Chen Ping had no expression on his face, took out a tube of green alum oil again and slowly poured it on the stone.

As time goes by, a strange stone flower gradually reveals its prototype.

Li Si's eyelids trembled and he quickly left the seat.

He frowned and thoughtful.

Mo Xun looked at Shi Hua curiously.

In this way, until the second tube of green alum oil was poured, a formed stone flower and several semi-formed petals appeared in front of the four people.

"This...this is incredible!"

Li Si stared at Shi Hua and couldn't help but sigh.

He glanced at him softly, and then pondered: "It seems that this vision is indeed artificial."

"Who did that?" Mo Xun frowned.

Li Si came to his senses, snorted coldly, and said, "Who else can have such great ability except those remnants of the Six Kingdoms with ulterior motives?"

As he said that, he looked around the three of them and said deeply: "I will report this to Your Majesty truthfully."

He nodded weakly, suddenly remembered something again, shook his head and said, "Before reporting to Your Majesty, there is something to prove."

"What's the matter?"

Li Si was a little confused.

But he heard the lightning and continued: "The stone blooms and the words bleed are bleeding. We can all prove that it is artificial, but how can we prove it when the stone grows out of the soil?"

"this……"

When Li Si heard this, he subconsciously looked at Chen Ping.

Chen Ping shook his head and said, "I don't know this either."

"you do not know?"

"I know I must answer truthfully, but I don't know."

When Li Si and the other two showed surprise expressions when they heard this.

They thought Chen Ping could completely crack the vision, but they didn't expect that they only cracked half of it.

This is a bit embarrassing.

Although they all believe that all visions are artificial, this kind of slight understanding is still very uncomfortable.

In fact, Li Si had doubted Chen Ping, but he just felt it was impossible, because he could not imagine that a small civil dared to call him to catch the thief in front of his three people...

What's more, this villain has not completely cracked the strange phenomenon.

After pondering for a while, Li Si turned to look at Mo Xun: "Are you really sure the soil under the strange rock has been renovated?"

"Sure."

Mo Xun nodded and said, "I have checked it myself, there will be no mistakes."

"Since that's the case, let's report to His Majesty together to see if we can remove the strange stone?"

"Is this...can this work?"

Mo Xun was a little hesitant.

Li Si frowned and asked, "Why can't it work? You have confirmed that the soil has been renovated, which means that it is very likely that it is artificial."

Mo Xun thought for a while and said helplessly: "Okay, I'll go with you to meet His Majesty."

After saying that, the two of them were about to get up and leave.

"etc."

Dunruo saw the two of them leaving and quickly spoke out: "How should Chen Ping arrange it?"
To be continued...
