"Huh?" Old Ren looked up at Su Chen in surprise. "My friend is so confident. In this way, I, the old guy, take advantage!"

"It should be, after all, I'm specializing in this. You're always interested. If you bet with me, you're always at a higher risk!"

"Haha, my friend is so open-minded that I feel ashamed. I will listen to you, what is the bet?"

"What do you always say?"

Mr. Ren narrowed his eyes slightly, thought for a while, and suddenly said, "Haha, I'm not intimidated by you. My family recently invited a world-famous chef. I want to invite my friend to visit my house. This way, if I lose, I will still visit my house tomorrow; but if my friend loses, then I will wait for my friend to come at home. How about it?"

Su Chen narrowed his eyes slightly, and he was stunned for a moment before he understood Mr. Ren's words.

This old man is so tiring to speak! The businessman is so virtuous.

"Success! It's up to your old wishes!"

"Okay, happy!" Mr. Ren was in a good mood.

Seeing this, Su Chen didn't know anything. He picked up the knife and gently slashed the head of the supervisor.

Bang!

The thin bamboo tube opened in response to the sound.

A roll of paper rolled into a stick fell out of it.

Su Chen carefully picked up the paper and did not rush to open it, because the paper was a bit old and very old, and the quality of the paper was not very good. It looked very crispy and opened easily, which may cause the paper to break.

"Huh? This paper? It seems to be ancient paper. It seems to be at least from Song Dynasty."

Papermaking actually undergoes many such leap-like changes. Among them, the biggest changes were the Han and Tang dynasties.

Needless to say, Cai Lun improved papermaking technology, which was a system for papermaking to truly achieve mass production of paper.

However, the quality of the paper during this period was average, very thin and crisp.

I only know that the Tang and Song dynasties had developed more and more powerfully, and the continuous improvement of papermaking technology has brought the quality of paper to some new levels.

The paper in Su Chen's hand seems to be of super poor quality. Either the folk songs and defective papers from after the Tang Dynasty, or the old papers from before the Tang Dynasty.

But it seems that the latter is extremely likely.

"Shopkeeper, you have a frame frame here, right? Please find one for me!"

When Manager Zhou saw that Su Chen had taken out another treasure, he was already thrusting with pain, and his eyes were dissipated. How could he listen to Su Chen's instructions?

However, Manager Tan had already recovered. When he heard Su Chen's words, he hurriedly ordered the shopkeepers.

"You haven't gone to find it yet? Choose the best one?"

Upon hearing this, the guy hurriedly ran to the back room.

On this side, Su Chen pretended to behave and reached out to his pocket. After a moment, he took out a glass cylindrical bottle, which was filled with viscous colorless liquid.

"Fortunately, I took him with me today."

Su Chen lied skillfully. The source of the thing must be the system mall. He did not have the habit of putting some bits and pieces of tools into his pocket. He usually likes to sell it on the spot.

No one doubted it, just curious.

"What is this?" Liang Tong asked.

Su Chen replied: "This is a kind of glue, you can understand it as fixing glue. Applying this thing to paper or fragile things will form a transparent film on the paper. This film is like the protective film of a mobile phone. It is extremely strong and tough, and can protect the fragile paper stuck to it.

To put it bluntly, applying it is equivalent to applying a transparent protective film to the paper!"

However, the next moment, Su Chen said something scary to everyone: "Who said this must be a fake?"
