"Then I understand. Please send me the list of items!"

Wang Yan talked to Shan Kai for a few more words and then ended the call.

While driving, he said to Tan Junyan, "Although walkie-talkies don't have as many functions as mobile phones, they don't require base stations or networks, making them more suitable for your area."

"There's no signal interference over there, so the call will be optimal."

"The most important thing is that the walkie-talkies sold by Dan Kai can be charged using solar energy, eliminating the trouble of charging difficulties you have."

Tan Junyan subconsciously asked, "What is electricity?"

"Electricity is...how do I tell you?"

Wang Yan seemed to be in a dilemma. After thinking for a moment, he said, "Electricity is a form of energy. Lightning is also electricity."

"But lightning is uncontrollable, the electricity we use is controllable."

"In our world, many things require electricity to run."

“Like a cell phone.”

"The battery in the phone you used to take pictures with can last for several days."

"The power went out in a few days and it was unusable."

"If you use it for too long, it might run out of power before the end of the day."

"It needs to be charged before it can be used again."

"And the lights you see all need electricity to shine."

"And that walkie-talkie can convert sunlight into electricity, which is stored in the battery inside."

"That way, the intercom can continue to work."

Tan Junyan seemed to understand what she heard, but also seemed not to understand.

She nodded, not quite understanding, and blinked her beautiful eyes and asked, "What are hot weapons?"

"That thing is incredibly powerful. Part of it is absolute truth, a powerful weapon that can change the world order."

Wang Yan became interested, slowed down the car, opened his phone, and searched for the introduction of the explosion of "Little Boy" and "Fat Man".

"This happened in the past. See for yourself how horrible it was."
