After giving his instructions, Zhuang Zhou returned to the backyard and took out a few of the items he had brought with him.

Then he went out and went to Wangji Trading Company to find Wang Zhigui.

I exchanged all the things I sold last time for gold and took it back.

The only remaining three strings of copper coins were also placed in a high-end imitation antique shop.

Zhuang Zhou is now penniless.

I also need to find Wang Zhigui to exchange some copper coins to keep it running.

…

Wangji Trading Company.

"Brother Zhuang, you said this thing is called a solar flashlight?"

Looking at the bright lamp in Zhuang Zhou's hand.

Wang Zhigui was completely stunned.

This thing is much brighter than an oil lamp.

But Wang Zhigui observed for a while and couldn't help asking:

"Brother Zhuang, I've been looking for a long time, but I can't find the wick for the ignition."

"Ha! This thing doesn't need ignition. See here? Press it once and it lights up. Press it again and it turns off."

Zhuang Zhou pressed the switch on the flashlight twice.

I saw the light suddenly go out and then come on again.

Wang Zhigui was completely shocked at this moment.

"This lamp doesn't need oil or candles, yet it shines so brightly. It's truly miraculous!"

As he spoke, Wang Zhigui bent down and stared at the flashlight.

"Brother Zhuang, today I have really broadened my horizons."

Zhuang Zhou immediately introduced himself:

"This lamp of mine not only doesn't require fuel, but also produces better light than an oil lamp and is harmless to the eyes. At night, when I turn on this lamp, it illuminates the road just like daytime."

"Yeah! It's really a good baby!"

Wang Zhigui can be confident because he has been operating in Chang'an City for many years.

Even the current emperor has never seen such a lamp.

He no longer hesitated and said directly:

"Brother Zhuang, you must sell me this lamp. Just name your price."
