"this……"

Wu Liang was already questioned.

He did know what the so-called "Water Alchemy, Yellow and White Technique" was. It was actually a branch of what people often call "Alchemy". To put it more bluntly, it was actually the legendary "Midas Touch".

.

In fact, the essence of this thing is very simple.

The alchemists of the ancient Chinese dynasty were actually doing the work of chemists of later generations. In order to refine the "elixir" that could make people "immortal, attain enlightenment and become immortals", they were so crazy that they used everything they could get in the world as raw materials for alchemy.

Give it a try.

In fact, there is no shortage of ordinary things such as ores, minerals, plants and herbs, as well as children's urine, human nails, hair, and even the dirty blood shed by women during menstruation...

In short, everything in the world can be made into elixir.

Therefore, nature will inevitably refine many strange things, among which the most widely known to later generations and the one with the greatest influence is naturally gunpowder.

However, although the alchemists had already refined gunpowder, its real value was developed in the late Tang Dynasty.

And "medicinal gold" is also a product obtained from alchemy.

However, Wu Liang is not sure whether "Midas Touch" really exists in the world. He only knows that some minerals and specific materials can indeed be refined to produce something with a golden color.

For example, mined coal is often mixed with some golden things.

These golden things are not gold, but are mainly composed of iron sulfide. Not only is it worthless at all, it will also make the coal emit a smell when it is burned, affecting the quality and price of the coal.

Therefore, the so-called "medicinal gold" may actually be something similar.

After all, minerals such as "sulfur" occupied a very important position in ancient alchemy.

But now that Hu Zhao asked, Wu Liang didn't know how to answer.

Should we talk to him about the chemistry of later generations?

Not to mention that Wu Liang has not passed the test in chemistry since high school. Even if he really knew chemistry, he probably wouldn't be able to explain it like this, thus denying the "Waitan Huangbaizhu".

After all, his current identity is "Mr. Wu", and "Mr. Wu" is also a Taoist. To deny "Waitan Huangbaishu" would be a slap in the face, and it would be difficult to convince Hu Zhao.

And Wu Liang has already realized it.

This question is really just an inconsequential appetizer.

When they first arrived, Hu Zhao and the Sima family must have doubted his abilities, so it was necessary to test him again before they would be willing to tell the truth about their secrets.

If you can't even pass this level, although you may not necessarily cause death for yourself and the Hu army, you won't be able to touch more secrets.

These secrets are most likely related to the Sima family and Wen County, or even to Wu Liang's visit to Wen County to investigate this time.

So after pondering for a moment.

"Mr. Kong Ming's question really stumps me."

Wu Liang said with a smile, "I am dissatisfied with Mr. Kong Ming. 'Waitan Huangbaishu' is an extremely profound Taoist skill and cannot be refined without a true master. Otherwise, the gold in this world would not be as precious as it is today."

, It is very rare for Mr. Kong Ming to be able to practice to this point, and I am not much better than Mr. Kong Ming. At most, I can only make some ingenious things that are breathtaking."

"A mind-blowing ingenuity?"

Hu Zhao was obviously not very satisfied with Wu Liang's answer, but his curiosity was aroused by Wu Liang's last words.

"For example, this thing was refined by me."
