The old eunuch stood aside. When he heard Han Du say that the treasure banknote was impervious to water, he opened his mouth as if he couldn't believe his ears.
Are there any treasures in this world that are not afraid of water?
But Han Du's next move made the old eunuch have no choice but to believe it.
When Lao Zhu saw the treasure banknotes presented to him by Han Du, his lips were trembling uncontrollably. The treasure banknote in front of me was covered with a layer of wet water, but the paper of the treasure banknote did not look soaked at all, and even the ink marks on it were not blurry at all.
Lao Zhu immediately took the treasure note from Han Du's hand, feeling the water stains on his hand, and became even more curious about the strangeness of the treasure note.
"It's amazing. It's really amazing. There is really no sign of being eroded by water. Han Du, you are an eye-opener for me."
If he hadn't seen it with his own eyes, Lao Zhu wouldn't have believed that there was paper in this world that was not damaged by water.
"Back to the emperor, strictly speaking, if this treasure banknote is soaked in water like just now, there will still be a little damage to this treasure banknote. But it is too small to be visible. According to my estimation, a treasure banknote You can withstand being soaked in water twenty or thirty times like this." Han Du said honestly.
Lao Zhu smiled broadly, not disappointed at all, and praised: "Even so, this treasure banknote can be called a miracle. After drying, will this treasure banknote be the same as before?"
Han Du smiled and replied: "It can be dried in the sun or wiped dry with a handkerchief. However, because it has just been soaked in water, it is a little softer than the treasure notes. It will recover after it is dried in the sun or baked."
When Lao Zhu heard this, he was extremely curious, as if he was being scratched by a cat. How could he wait here in vain? He waved his hand and said, "Hurry up and get me a handkerchief."
As a result, Lao Zhu carefully wiped the water with his handkerchief. When he saw that the handwriting and texture printed on the paper had not changed at all, he was immediately very satisfied.
He casually handed the dried treasure banknote to the old eunuch, "Take it and quickly dry it. I want to see if it is the same as before."
The old eunuch accepted it in response, and within a short meal, the old eunuch came back with the dried treasure banknotes.
"Your Majesty, please take a look."
Lao Zhu quickly brought the treasure note to his eyes and pulled it with his hands. He felt that it was almost the same as the original treasure note.
"Okay, good stuff." Lao Zhu smiled happily, maybe he was so happy when he married his wife.
He turned back to Han Du and said, "What did you say just now? If there is anything else strange, let me hear it."
Han Du smiled and pointed to a spot on the banknote, "Your Majesty, please look here."
"This is this?" Lao Zhu looked at the place pointed by Han Du's finger, which was completely blank, and he didn't know why.
Han Du continued, "Your Majesty, please hold the banknote higher towards the light."
Although Lao Zhu didn't understand why, he still did as Han Du said.
I saw that as the light passed through the treasure banknote, another half-length portrait of myself appeared in the originally blank space, clearly visible. When you look at it like this, the portrait is much brighter than the rest of the paper, as if the portrait is glowing, with a sacred meaning.
At this time, Lao Zhu was truly shocked.
In disbelief, Lao Zhu took off the treasure note and put it back again, going back and forth several times. You can't see it when you take it off, but you can see it when you hold it up to the light.
"This, this..." Lao Zhu murmured to himself and asked Han Du in disbelief: "How did you do this?"
Han Du smiled and said nothing.
Lao Zhu pondered for a moment, then came to his senses and waved his hand for everyone else to go out.
Han Du then explained to Lao Zhu: "Your Majesty, this is called a watermark. It is pressed out with a wire roller before the paper pulp solidifies during paper making."
"Is that true?" Lao Zhu looked at Han Du solemnly, his meaning unclear.
Han Du was stunned when he heard this. If it’s not like this, how can it still be like that? Seeing Lao Zhu's strange and incomprehensible expression, Han Du couldn't help but feel cold in his heart, "Well, isn't this Lao Zhu thinking of other mysterious things?"
Only then did Han Du realize that this might really be possible. Although this watermark seemed commonplace to him, for Lao Zhu, he might even believe it if it was a manifestation of a deity.
But he told Lao Zhu that this was done. This, if I can't explain it well, I might not be able to leave Fengtian Hall today.
Han Du was about to break out in a cold sweat, so he braced himself and explained: "That's it."
Han Du said categorically.
"This was made in the Banknote Bureau. The wire roller is still in the Banknote Bureau. If the Emperor has any doubts, he can issue an order now and let the people in the Banknote Bureau make this paper."
After listening to Han Du's explanation, Lao Zhu's expression softened a lot. Regarding Han Du's proposal, Lao Zhu was no longer as eager as before. Since the craftsmen of the Banknote Bureau can make this watermark, there is nothing to worry about. It turns out that Lao Zhu was able to make it only through Han Du in the past, so he naturally had a somewhat mysterious association with Han Du.
After thinking about it, Lao Zhu sighed and said, "Forget it, let's wait until we have the chance to talk about it. By the way, your paper is so good and even invulnerable to water. How did you make it?"
Seeing Lao Zhu's expression softening, Han Du knew in his heart that this test was over.
Feeling relieved, I replied seriously: "Back to the Emperor, this paper is made of cotton."
"Cotton?" Han Du's answer surprised Lao Zhu. He had never heard that cotton could be used to make paper, and the paper produced was still of such high quality.
Han Du nodded and replied affirmatively: "It's cotton. In order to prevent others from counterfeiting the banknotes, the first thing I thought of was to make the paper of the banknotes unique so that people can tell the authenticity of the banknotes at a glance. So after many attempts, a suitable banknote paper was made from cotton."
Han Du deliberately explained the origin of the banknote paper in order to conceal why cotton was used to make the banknote paper in the first place. At that time, even if Lao Zhu didn't believe it, Han Du could shirk the fact that the only materials in the banknote bureau were cotton and cotton.
Hearing this, Lao Zhu pondered for a long time, a cold light flashed in his eyes, looked at Han Du with unknown meaning, and asked: "So, the craftsmen of the banknote bureau also know that the banknotes are made of cotton?"
what does this mean? After all, this banknote was made by craftsmen, how could they not know?
Han Du looked at Lao Zhu blankly, and saw the dangerous light in Lao Zhu's eyes, and then he instantly realized that Lao Zhu had murderous intentions!
