My hotel is full of emperors throughout history.

Upon hearing this, Li Shimin and Liu Che also spoke up without hesitation.

The cost isn't important; the problem is that the benefits are enormous.

It can transmit information no matter how far the distance, so it would be a godsend when used in the military.

At that time, military orders and various government decrees can be disseminated immediately.

Once this thing is actually put into use, it will truly be a weapon of mass destruction, a weapon of mass destruction that transcends its time.

However, Chen Mo only frowned, considered the feasibility for a moment, and then quickly shook his head.

"No, using this requires not only a signal tower, but also fiber optic cables and a whole host of other things, and it needs electricity. Do you have electricity where you are?"

"I can send over a small generator or a small solar generator, but those things are only for low-power devices like lights. For high-power voltage, we need to build a power plant."

Chen Mo looked at the three of them.

"With current technology, it's naturally very simple, but where you are..."

Chen Mo did not continue speaking, and Zhu Yuanzhang and the other two understood his meaning and fell silent.

It's like modern people acquiring future technology but being unable to solve even the most basic energy problem, let alone utilize it.

Chen Mo continued.

"And if you were to actually build such a power plant, signal tower, and all that equipment, would you have the technical personnel to maintain the buildings?"

Upon hearing this, Zhu Yuanzhang opened his mouth, but Chen Mo waved his hand first.

"Don't tell me about the craftsmen involved; the two are completely different."

"The difference is like that between a beggar and an emperor, worlds apart."

As Chen Mo finished speaking, the entire ward fell silent.

Chen Mo looked at the three somewhat disappointed people, pondered for a moment, and then spoke.

"Although cell phones are not an option, walkie-talkies might be."

"A walkie-talkie?"

Li Shimin and the other two raised their heads at the same time.

"That's right, a walkie-talkie."

Chen Mo nodded.

"Walkie-talkies are not as demanding to use. They can be used for short distances even without a signal, and long-distance communication is possible after a signal tower is installed."

"It's practically an essential for murder, a must-have for home and travel, and now it's only 198... pshaw..."

Seeing the strange looks in the three people's eyes, Chen Mo quickly changed his tune.

"If you want walkie-talkies, I can help you buy them."

Li Shimin and the other two exchanged glances.

"In that case, let's start with a hundred units!"

Liu Che waved his hand and said.

Li Shimin was more cautious.

"Give me fifty units first!"

In comparison, Old Zhu was not so generous.

"Let's order twenty units. If they work well, we'll order more!"

After Zhu Yuanzhang finished speaking, he pondered for a moment and then looked at Chen Mo.

"If it doesn't work well, can we return it?"

"Father..."

Zhu Biao, who was standing nearby, was both amused and exasperated upon hearing this.

"We can still take money from the national treasury; if all else fails, we can take it from my private treasury."

"Never mind that! We have our own plans!"

"We need to spend our money wisely!"

Old Zhu waved his hand and looked at Chen Mo again.

"Compared to a walkie-talkie, do you have a camera?"

"Give us three hundred first!"

Old Zhu paused for a moment and then gestured with his hand.

"If possible, the best is the kind that's hard to spot, and yet clearly visible at night!"

"..."

Chen Mo and Zhu Biao's lips twitched simultaneously.

Seeing this, Old Zhu thought Chen Mo felt he hadn't bought enough, and raised an eyebrow.

"If it works well, we'll order again!"

Old Zhu was unusually generous.

"Ordering a thousand or even tens of thousands at that time is not out of the question."

Upon hearing this, Chen Mo's lips twitched even more violently.

With so many cameras, is Zhu Yuanzhang trying to monitor the entire Ming Dynasty?

An emoji inexplicably popped into his mind.

Replace Li Shimin's phrase "I want to control the armies of the realm" with Zhu Yuanzhang's, and change the wording to "I want to monitor all officials of the realm!"
