"I have a method that can test the demonic qi, do you dare to try it?" Deng Mao walked out and pointed at Ma Qiang and shouted.

"Come on, come on."

Ma Qiang can see that the so-called Taoist technique used by Taiping Dao now is the stage of the Tianqiao trick in later generations, and I am afraid that even Zuo Ci will not be able to change into a live fish.

"Look! This is the demon inspection bottle on Kunlun Mountain! ”

Deng Mao took out a transparent bottle with a wide mouth and a square bottom, although it was not as good as the glass of later generations, but it was also the best in this era.

China's mass production of glass has been a matter after the Qing Dynasty, but in fact, as early as the Warring States Period, China had glassware, but the production was extremely low, and a large number of glass ornaments were unearthed in the Western Han and Eastern Han Dynasty, and even Roman glass products were excavated in China.

"You're in a good bottle, where was it made? Do you know this craftsman? ”

Ma Qiang now finds that the craftsmen of this era are really not to be underestimated, although they do not understand all kinds of scientific principles, but they can make crafts beyond imagination according to experience.

Yes, in Ma Qiang's view, products that cannot be mass-produced cannot be called industrial products at all, but can only be called handicrafts.

"Demon boy! Let me see your demonic geometry! ”

As he spoke, Deng Mao asked people to pour water into the bottle, and then chanted a mantra in his mouth, holding a yellow talisman in his hand, and it burned in a flash.

Isn't there anything new? Looking at this old routine, Ma Qiang almost wanted to doze off.

When the yellow talisman was halfway burned, Deng Mao shook his hand, holding the black ash in his hand, threw it into the bottle, and then shook it.

"There are traces of demonic energy!"

Before the words fell, everyone saw that strands of black water came out of this demon inspection bottle, and the black water stained the entire bottle of water black.

"What a demon! The demon boy is still in the law? ”

"I said," Guo Jin cried out, "you can't have lost some ink!" ”

"yes, just throw some ink and that's it."

"Is the black ash the appearance of dried ink?"

"Guo Jin, you are so amazing!" Lu Qinglime looked at him with some admiration, which made Guo Jin even more arrogant, "I think you really don't have any skills in Taiping Dao, so you are embarrassed to come up with this deceptive trick?" ”

"Ignorant fools! Watch me finish! ”

As he spoke, Deng Mao shook the bottle in another direction, and there were words in his mouth, and a magical scene appeared, the black water slowly faded, and finally turned into clear water.

At this moment, everyone was speechless, and everyone could understand that the clear water turned black, but this black water turned into clear water, how could there be such a thing in the world?

"Is it really the Immortal Law?"

"Ah, that's not to say that kid is really a monster!"

"Thanks to the presence of the immortal master, otherwise I wouldn't know that there are monsters doing it."

"Burn him! Otherwise, there will be a plague! ”

"Burn him! Burn him!! ”

Some people were even more excited and began to throw things at Ma Qiang, Ma Qiang flashed a vegetable gang, thinking that there were no eggs in his head, these people were really stingy.

"Shut up!" Xian Yuyin roared, drew his sword and shouted below, "This is just a trick of the demon road, right?" Ma Lang? ”

Ma Qiang looked at Xian Yuyin and nodded, and then said with a smile: "Good spell, really, you don't study the principle of such a skill well, but you deceive people here, you really bury talents." ”

Seeing Ma Qiang so indifferent, everyone wondered again, is this also a lie?

"You call me a liar? Can you too? Deng Mao's mouth was tough, but his palms were a little sweaty.

"Of course, but I need some time, Qingcheng, you come over and help me prepare."

"Come on!" When Lu Qingcheng heard this, he jumped on the fighting platform with great joy, and Guo Jin and others also followed.

"Go get these. . . And also... And then like this... Do you understand? ”

Several people glanced at each other, although they didn't understand, but they still nodded and said, "No!" ”

Seeing a group of people in the tent and not knowing what to do, Deng Mao felt a little bad, isn't this a repetition of the previous scene.

"First of all, you're not testing demonic energy at all, it's just a simple chemical reaction... It's okay, you don't understand me and I'm going to be simple. ”

"Brother Pony, I've got something!" Lu Qingcheng walked up with a lot of things.

"First of all... Liu Yuanjun, do you want to come and play? ”

When Liu Wei heard this, he was energetic, and pointed to himself excitedly and said, "I... Can I do it too? ”

"After knowing the truth, everyone can do it, that's called science, come on!"

"Good!" Liu Wei ran up in a hurry, and Guo Xun was a little jealous... He also kind of wants to play.. Ahem, I want to verify its authenticity.

"First of all, I'm afraid that your bottle is not water at all, but tea, tea contains a thing called tannin, and the thing you just dropped is not black ash, but ferrous sulfate, also called alum, which reacts with the tannic acid in the tea to form ferrous tannin, and it turns black."

As he spoke, Ma Qiang took out a glass cup that was not very transparent, this cup was still borrowed from Zhang Sheng, poured tea into the glass cup, and then handed Liu Wei a little green alum, signaling to throw it in.

Liu Wei carefully threw away a little green alum, Ma Qiang swayed, and a magical scene appeared, and the tea that had just been clear immediately became pitch black.

"Ahh It's really getting dark! ”

"Then, ferrous tannic acid itself is unstable and will soon be oxidized to iron tannic acid to form a blue-black complex... Forget it, if you don't understand, just remember how to do it, and after a while, just add a little oxalic acid... It is a kind of thing extracted from barberry and sheep's hoof, as long as it is dried and turned into crystals, it is very easy to use, come, Liu Yuanjun will try it again. ”

With Ma Qiang's words, Liu Wei put a little less pure oxalic acid into it, and then began to turn the glass cup in his hand, although this cup was not very transparent, everyone could still see that the water in the bottle began to fade from black.

"Clear! It's really clear!! ”

"If you're interested, you can prepare some materials for testing, the result must be the same, okay, Demon Dao, your demon inspection bottle was also broken by me, do you have anything else to say?"

Seeing that Ma Qiang had once again cracked the Dao method on his side, Cheng Zhiyuan couldn't stand it anymore, and yelled, "Boy, you have repeatedly and repeatedly opposed my Taiping Dao, who are you!" ”

"Me? I'm nothing but a scientist! Ma Qiang tilted his head and smiled.

"Scientists? What is that? ”

"Demon Dao, you've already shot three times, now it's my turn!" Ma Qiang's eyes were certain, and he shouted in his mouth, "Five Thunder Rectification!" ”

As soon as the words fell, a corner of the fighting platform exploded, and the firelight, smoke, and loud noise made everyone stunned, and some people didn't even know that the things in their hands had fallen, but they just looked at the corner of the fighting platform.

Black powder, haven't you seen it? You're the only one who buried something? It's all a thousand-year-old fox, what are you talking about?
