Standing on the city wall, Cheng Chubi took out a copper pipe, put it in front of his eyes, and squinted his eyes to look inside.

Soon, the distant scene appeared in sight, Cheng Chubi nodded with satisfaction, and said, "Not bad, that's the effect!" ”

"Husband, what are you doing?" Chai Lingyu looked at Cheng Chubi with a puzzled expression, I don't know what kind of thing my lovely husband has come up with, could it be that this copper pipe is something else?

"See for yourself." Cheng Chubi smiled and said, although it is a single-hole glasses, but the effect is already very good, for his own work, Cheng Chubi is still quite satisfied.

This is a work that I have been pondering for two days, and I have not been able to correct the focal length several times.

"What is this?" Chai Lingyu took it with a puzzled face, and then began to look at it, and the next second, the whole person couldn't help but be stunned.

"I saw it, I saw it, I saw it a thousand kilometers away, this ...... Could this thing be the legendary clairvoyant? Chai Lingyu couldn't help but be shocked, and then overjoyed!

If you have this thing, won't you be able to see things far away for a long time, which is quite good for marching and fighting, it's like having a clairvoyant.

It's amazing that you can spot the enemy as soon as you get close, and if you run away, you can spot it yourself.

"That's right, it's claireye. But don't move around, I've installed a mechanism for this thing, and it will break if you take it apart. Cheng Chubi showed a hint of pride on his face, now he knows how powerful the master is, right? Minutes to make you surrender.

"Can this thing be mass-produced?" Chai Lingyu couldn't help asking.

"Theoretically, yes." Cheng Chubi nodded and said, "As long as there is a crystal or glass with good transparency, it can be made, but you also know that crystals with such good transparency and such large crystals are not common." ”

"As for glass, well, although there was some glass in this era, I don't know much about the manufacturing process, it seems to be made by firing fine sand." Cheng Chubi thought about it, and it seemed that the glass was made of sand after firing.

"What? Seriously? ”

"It's true!"

"That thief and thief are really made of sand?" Chai Lingyu couldn't help but feel a little moved.

"It's made of sand burning, but it has to add some minerals to it, so it can be cleared, but I can't remember which mineral was used." Cheng Chubi shook his head helplessly, he really couldn't think of it.

"Hey, that's a shame." Chai Lingyu couldn't help sighing, if this thing can be mass-produced, it can definitely become an artifact for his own marching and fighting.

"Last time, that guy lost quite a lot of crystals, quite a lot, so I made eight clairvoyants." Cheng Chubi looked at Chai Lingyu with a wicked smile on his face and said, "How do you reward me?" ”

"How do you want me to reward you?"

"Let's unlock a new pose tonight." The evil smile on Cheng Chubi's face became even richer.

Chai Lingyu's ears couldn't help but turn red, and he said in a very low voice: "Okay." ”

Cheng Chubi was really happy in his heart, and he couldn't wait for it to get dark now, and then explore a new realm together.

Night finally fell.

And at this time, in the palace of the Tang Dynasty.

A figure hurriedly walked inside, it was a Datang internal guard, responsible for monitoring Cheng Chubi.

The figure entered the main hall, and then knelt on one knee, his face pale.

"Coming back? Could it be that the Cheng family also entered the city? Li Shimin's brows furrowed slightly, the Cheng family entered Chang'an, and he should be the first to get the news, but there was no news all day?

Li Shimin likes the feeling of being in control of everything, and anything that is out of his grasp will make him feel a little uneasy.

"No...... No! The look of horror on the guard's face intensified.

"Oh? So what the hell is going on? ”

"Cheng Jia Saburo, missing!"

"What?" Li Shimin stood up from his position and said, "Didn't I let you stare at him?" Why did he go missing? Did you escape? ”

A murderous intent couldn't help flashing through Li Shimin's eyes.

"No, Zhijie will not betray me if he follows me from birth to death, as long as Zhijie is still alive, the Cheng family will not rebel." Soon, he sat on the ground again, then shook his head and sighed: "Cheng Sanlang, Cheng Sanlang, what do you want, what do you want?" ”

"What's going on over there with Yu'er?" Suddenly, he asked.

"Your Majesty, the princess has not replied yet, and everything has not changed." Li Zhong opened his mouth and said.

"That's good, Li Zhong, you said that this 'heroine Chang' is the same as Li Junxian, will it be Yu'er?" Li Shimin asked.

"Your Majesty, the princess is a member of the royal family."

"But she's a foreign surname after all." Li Shimin couldn't help but sigh and said.

Even if he is a member of the royal family, he guards his sons the same, not to mention a general with a foreign surname who leads troops, Li Yuan and Yang Guang are relatives, and they are not the same as killing Yang Guang's descendants and winning the world?

In front of the throne, even father and son are enemies, let alone others.

Therefore, the emperor can never trust a person, the lesson of history, anyone who trusts a minister too much will kill himself and his family.

Perhaps, this is the so-called loneliness.

At the same time, in the southwest direction of a small town.

A figure sat quietly on the edge of the bed, not knowing what he was thinking.

This person is none other than the long history of Wu Wangfu, Quan Wanji!

King Wu's arrow did not kill him, allowing him to pick up a life, and at the same time he held a grudge against King Wu.

After resting for a while, his body was much better, and he thought that it was time to leave, and it was time to return to Chang'an.

"Li Ke, this revenge is not a gentleman! You wait, you wait for me, when I return to Chang'an, I will definitely play to Your Majesty, you just wait to accept Your Majesty's wrath! Quan Wanji couldn't help but say angrily, clenching his fists tightly.

"Squeak!"

At this time, the door opened, and then a fat woman in her thirties, more than 300 pounds, walked in with a smile and said happily: "Husband, it's time to go to bed peacefully." ”

As he spoke, he gave Quan Wanji a wink, and Quan Wanji's clenched hand tightened even tighter, almost bursting into green tendons.

"The tiger fell in Pingyang and was bullied by dogs, the tiger fell in Pingyang and was bullied by dogs, all of this was caused by Li Ke, Li Ke, a certain and you are not finished!" Quan Wanji said secretly.
