Unconsciously, Qin Tianyuan had already walked to Qin Lang's side.

But his eyes were still fixed on the standing street lamp.

He knew it all too well.

It's just that what he didn't expect was that this thing that Qin Lang asked him to make made was so useful!

"Your Royal Highness the Prince, this king remembers, you said this thing is a street lamp, right?"

"Not bad!"

Qin Lang did not deny it.

"How did you come up with the idea to build this?"

"Nature is to observe the usefulness of the Sun and Moon Stone, as well as its advantages and disadvantages."

Qin Lang casually made up a lie.

Hearing what Qin Lang said was half-true and half-false, Qin Tianyuan didn't ask.

The other party chooses to conceal it, and it has his own intentions.

"Uncle Huang, if this thing is all over the Imperial City, or even the entire Great Qin Dynasty, what kind of scene do you guess it will be?"

The corners of Qin Lang's mouth were slightly hooked, and his eyes were looking forward to the future imperial city.

"If this street lamp appears in various parts of my Great Qin Dynasty, it will definitely be a leap reform."

Qin Tianyuan's tone revealed excitement, and his face was full of anticipation that this thing would spread all over the Great Qin Dynasty.

Don't look at the lighting it provides.

But the advantages it showed were enough to shake the Great Qin Dynasty.

They can even sell it to the six major dynasties and even the five major sects to make a big profit.

"Uncle Huang, before this thing spreads all over the imperial city, and even the entire Great Qin Dynasty, Gu wants you to place the street lamps in the entire Zongren Mansion first, and help Gu return to the court as soon as possible."

"Is it necessary to be so fast?"

Qin Tianyuan's brows furrowed, and his face was slightly worried.

"How is that possible?! The street lamp is just paving the way, and if you really want to return to the court, you need a major thing to help the orphans. ”

Qin Lang broke his hands with a helpless expression.

The streetlights were just a tranquilizer for him.

It is also a ploy to divert the attention of all parties.

"If you want this thing to be all over the Zongren Mansion, you have to ask Your Majesty for money."

Qin Tianyuan's face revealed a dignified expression.

The monthly salaries of the "Zongren Mansion" are fixed.

Even if there is a trend of going up and down, it is within the control range.

To produce this in large quantities, it would require a lot of materials and the involvement of many blacksmiths.

After pondering for a moment, Qin Lang said, "How many forgers do you have in your hands?" ”

A forger and a refiner are two different professions.

The blacksmith mainly crafts objects such as doors, tiled floors, and bricks with inscriptions.

These include crossbows, trebuchets, and climbing vehicles.

The refiner mainly refines various magic weapons.

"Twenty-eight."

"How long does it take for a person to make a street lamp?"

"With the guarantee of quality and durability, it takes at least a day or two."

After thinking for a while, Qin Tianyuan said slowly.

"Is the material in your hand enough to make the street lamps needed for the Zongren Mansion?"

"The Zongren Mansion is too big, and the materials in the hands of this king are simply not enough to make the street lamps needed by the Zongren Mansion! You can only make up to one-fifth of the amount. ”

Qin Lang was directly silent.

After a long time, he spoke: "During this time, can there be an auction in the imperial city?" ”

After thinking about it carefully, Qin Tianyuan said: "In three days, the Chiba Auction will hold an annual large-scale auction. ”

Qin Lang took out a delicate pill bottle from the system space, handed it to Qin Tianyuan, and said, "This is a Zhuyan Pill, you take it to the Chiba Auction for auction." All the money obtained is used to buy materials to make street lights. ”

"Zhu Yan Dan?"

As soon as he took the pill bottle, Qin Tianyuan was stunned for a moment, and looked at the object in his hand with blank eyes.

With an incredulous face, he said, "How can you have such a good thing as Zhuyan Dan?" ”

Zhuyan Dan not only needs to be refined by alchemists of more than four grades, but the ninety-nine eighty-one materials it needs are not only expensive, but also very rare.

After taking it, it can make people stay young forever, and even make people more captivated.

Even if the life is over, the beauty is still preserved as before.

What he didn't expect was that Qin Lang actually had such a good thing!

"I got it a long time ago."

Qin Lang casually made up a lie.

"Wouldn't it be a bit ...... if you don't give such a good thing to your aunt, but take it to auction?"

Qin Tianyuan looked up at Qin Lang, his face was a little surprised, and he was a little regretful.

Zhu Yan Dan is what countless women need.

This kid didn't give it to his aunt, but took it to auction, which is a bit stingy.

"Stop! There are two Zhuyan Pills on Lone's body, one is auctioned, and the other is left by Lone for his aunt. ”

Before he could finish speaking, Qin Lang opened his mouth to stop it.

"Uh~"

Hearing that Qin Lang had two, Qin Tianyuan was directly stunned.

"Where did you get this good thing?"

"I got it by accident a few months ago."

didn't hear a specific one, and Qin Tianyuan didn't ask anymore.

"Tomorrow, this king will send this item to the Chiba auction, and let them spread the news to the imperial city to attract the attention of those high-ranking officials and nobles and wealthy families."

As soon as the words fell, Qin Tianyuan put the Dan bottle into the "Space Ring".

After greeting Qin Lang for a while, Qin Tianyuan left the "Zongren Mansion" with his daughter.

Qin Lang returned to his room.

At the same time, the news that there were street lamps in Qin Lang's place of residence also reached the emperor's ears as soon as possible.

Qin Tianlong, who was located under the pavilion of Changmingyuan, couldn't help but be a little curious when he learned that such an object had appeared.

"By the way, the prince, what is the specific name of the thing that appeared in the courtyard where the prince is?"

Qin Tianlong asked curiously.

"Back to Your Majesty, listen to the guard standing outside the gate of the prince's courtyard, that thing is called a street lamp."

"Interesting!"

A faint smile appeared on Qin Tianlong's face.

"Let people block the news for the time being, and don't let anyone outside the Zongren Mansion know about it for the time being."

"But...... Your Majesty, His Royal Highness the Crown Prince made this thing, obviously wanting to return to the court, if the news is blocked, it will definitely postpone His Highness's return to the court. ”

Wang Wei showed a hint of hesitation on his face.

Qin Tianlong did not answer.

He knew that his son wanted to return to the court, but this matter had to be carefully considered.

After all, he had just made a rebellion.

After being silent for a long time, he spoke: "Then don't worry about it, let it continue to develop." ”

"No!"

The next day at noon.

The "Chiba Auction" was officially announced, and a "Zhuyan Dan" joined the auction.

With only half a stick of incense, the whole news swept the entire imperial city, and everyone was shocked.

Countless rich women have begun to prepare funds to win this coveted "Zhuyan Dan".

Zongren's House.

Qin Lang, who was idle and had nothing to do, was walking around with Qin Xi.

After walking for a while, they saw ten guards of the "Zongren Mansion", with a young man with a delicate face, a bright spirit, a height of two hundred centimeters, and a young man of about seventeen or eighteen years old.

"See His Royal Highness the Crown Prince."

As soon as the ten guards saw Qin Lang, they immediately knelt on the ground and saluted.

The young man who was handcuffed by iron chains looked at Qin Lang with a frown.

"Seeing Lonely, why don't you kneel?"

Qin Lang's eyes were ruthless, his face was cold, and his tone was full of irresistible majesty.
