As soon as Li Yuan finished speaking, Li Jing and Cui Shang next to him suddenly showed a sudden expression of enlightenment.

Cui Shang was shocked and said, "You asked me to do business, but you don't have gold and silver, just slaves... It turns out that it's for this?"

"For which one?" Li Yuan looked puzzled.

Li Jing showed a thoughtful expression and nodded slightly, "This move is feasible, it's just a little shameless."

Cui Shang smiled at Li Yuan and said, "Donald Tang thought, what is the greatest ability of those people?"

Li Yuan didn't care: "What else can they do except cheat and cheat?"

Cui Shang and Xi Yunfei smiled at each other. Things have to be different. Sometimes, there must be something hateful about poor people.

"If you want to talk about the greatest ability of a human being, it must be slave to human nature." Cui Shang sighed: "When I was working in Luozhou, I saw a steadfast woman who was turned into a lustful (harmonious) child (harmonious) woman. It took only three days before and after. When I interrogated that Yazi, the woman came forward to say good things for Yazi, saying that she was willing to go out for the flesh and blood for Yazi. Alas, now that I think about it, it makes people sigh."

"There is such a thing?" Li Yuan was shocked and dropped his chin when he heard this.

Xi Yunfei turned his head and looked at Li Lizhi. The little girl blushed and hurriedly covered her ears with her hands.

Li Jing looked at Xi Yunfei thoughtfully and nodded, "The same moves are also used to tame death soldiers. People with skillful methods can even use them for him without fear of life and death."

Li Yuan's eyes lit up. He didn't see the human teeth, but he was familiar with the people who tamed the dead soldiers, because there was one around him... But now it seems that these two people have the same fate, but one is just for their own selfish interests, and the other is to assist the monarch in achieving great achievements.

"Erlang means... to tame a large number of Goguryeo slaves and let them return to Goguryeo to mess with the situation?" Li Yuan suddenly remembered the former Sui Dynasty's plan to split the East and West Turks, but it only caused the civil strife of Goguryeo, which obviously could not satisfy Li Yuan's ambitions.

"Although this method is also good, I feel that the method you mentioned yesterday is more passionate and exciting. Can't we just destroy Goguryeo? We have to fix these false ones?"

Li Jing and Cui Shang also looked at Xi Yunfei with confusion. Although the solution was a good idea, in their opinion, if Xi Yunfei wanted to destroy Goguryeo, it would be easier.

However, they didn't know Xi Yunfei's hardship. As one of the thousands of time travelers of China Literature Group, he also had his own difficulties.

Although his current methods seem a bit ingenious, Xi Yunfei still wants to conquer Goguryeo in a more tactful way, instead of directly sending out more than a dozen airships to finish it in a crushing way. After all, he is only fifteen years old and his days are still long in the future.

"Three, don't look at me like this. There are reasons for me to do this. And which one do you think is better, a Goguryeo that was bombed to pieces or a Goguryeo that can continuously provide us with productivity?"

"This..." the three of them looked at each other, as if what Xi Yunfei said made sense.

Since the founding of the Tang Dynasty, the population has been at a bottleneck of tens of millions. Since the Sui Dynasty, the population of the Central Plains has decreased year by year. Some of these people died of the harsh criticism of corvee service. It is said that hundreds of thousands of people died after a canal was built... and some died in the three expeditions of Goguryeo. According to incomplete statistics, the three expeditions were exhausted and the number of people was directly or indirectly as many as one million.

Then there was the sudden rise of rebels in the rebel army at the end of the Sui Dynasty, and the conquests continued in the Central Plains, and the population decreased rapidly from more than 50 million...

By the early years of Zhenguan, the population of the Tang Dynasty was only a little over 10 million. In order to restore the population, Li Shimin had no choice but to promulgate a series of measures. In addition to redeeming the outflow population, he also encouraged marriage and childbirth. Not only did he let the palace maids who were suitable for marriage be free, but he also encouraged widows to remarry. Local governments also used the increase in the marriage status and household registration of the people as a hard indicator for evaluating the political achievements of local officials.

The Tang Dynasty lacks people, which is a fact that everyone here knows. Li Yuan and the other two were speechless and could not refute it.

"Then let's do as you said." Li Yuan finally compromised. Although there was no pleasure in crushing, he would be very happy as long as he could make Goguryeo bow down to the Tang Dynasty.

Afterwards, the four of them discussed the layout, especially Cui Shang. After all, he was the first shot of the third economic company this time. If he dropped the chain, he would not have to shoot the next second shot and the third shot.

Time soon came to dusk, the yard was already a little cold, and the solar energy-saving lights in the corner automatically lit up.

This is the first time Cui Shang has seen such a magical thing. After Xi Yunfei became popular, he asked casually: "Can this power device be sold for me?"

Cui Shang asked this question out of his love for novel things, but after he asked, the atmosphere in the yard suddenly became stagnant... Cui Shang then remembered that no one would sell such a magical object at will. Isn’t this just giving people the opportunity to imitate and explore!

"Haha, Erlang, I'm so straightforward, haha..."

"Ah?" Xi Yunfei saw that he was busy apologizing and said disappointedly: "Don't you buy it?"

Li Yuan and Li Jing were stunned when they heard this, while Li Lizhi covered her mouth and looked at Xi Yunfei in surprise.

Cui Shang was stunned: "What does Erlang mean?"

Xi Yunfei pointed to the energy-saving lamp in the corner of the courtyard and said, "Don't you want to buy it? I'll sell it."

"Really?" Choi Shang was surprised.

Li Yuan and Li Jing's breathing became rapid.

Xi Yunfei nodded to the three of them: "I really sell it. I was always wondering that no one came to buy such a good thing, but I didn't expect to meet the buyer today, hahaha."

"This..." Li Jing was confused and thought to himself: It's not that no one wants to buy it, but that no one has the nerve to mention it. You don't put it in the Chamber of Commerce to buy and sell it. Who knows that you don't care about such a good thing.

"Then I want a few sets?" Li Yuan was not willing to be outdone. This thing is a good thing, brighter than an oil lamp: "I just don't know the price?"

Cui Shang and Li Jing also looked expectant: "Yes, Erlang, this price?"

Xi Yunfei calculated his fingers and took the whole thing: "A solar charging panel that is 50 sq., a battery of 10 sq., a wire of 10 sq., a hundred sq., other switches and energy-saving lamps, I will give you a few sets for free. If you want to buy more, I will ask Ma Zhou to offer you a price list."

Li Yuan and the other two looked at each other: "Erlang, are you really selling it to us?"

"Why not sell it?" Xi Yunfei asked back.

"Aren't you afraid that I will imitate it?" Cui Shang said, looking at Li Yuan awkwardly. They didn't have too many skilled craftsmen in their hands. They imitated something, as long as there were physical objects, it would take a minute to do it.

Upon hearing this, Xi Yunfei glanced at Cui Shang with a strange look, and after a long time, he smiled: "Head of Cui, if you can really imitate it, I will give you another big deal with annual income of tens of millions of yuan."

"Thousands, tens of millions of coins?" Cui Shang took a deep breath: "Be serious about this?"

Xi Yunfei was funny and angry. This guy really thought he could imitate modern items, so he nodded: "It's true!"
