After Chu Yan finished speaking, he didn't wait for Yao Changan to say anything more, and strode out of the Taoist temple.

Chu Xuan hurriedly followed.

He was very curious about the old immortal now, but he didn't want to ask too much in front of Yao Changan.

So after leaving the Taoist temple, he quickly asked impatiently, "Brother, what's the matter with the old immortal you just mentioned?" ”

Chu Yan glanced at him coldly, although he didn't intend to hide him, he didn't intend to pull Su Jinli in.

So he just said, "Didn't you say that before?" The little uncle's face was cured by the old fairy. ”

Chu Xuan was not very satisfied, he knew this, but he didn't ask about this!

He quickly asked, "What else?" What does that old fairy look like? ”

Chu Yan refused to say more: "This is not the place to talk, go back and talk about it." ”

He is very wary of Yao Changan now, where is he willing to say more here?

Although they left the Taoist temple, since Yao Changan could see the aura, the peace card he took out was also a little extraordinary, maybe there was some magic magic.

This place is too close to the Taoist temple, and what they say here may be heard by Yao Changan.

You have to be on guard!

When Chu Xuan heard him say this, he had to keep his mouth shut silently.

He didn't expect so much, but he was a little afraid of Chu Yan, the second brother, seeing that Chu Yan's face was not very good, where did he dare to continue asking?

What if he annoys Chu Yan and Chu Yan asks him for advice?

He's going to be killed!

Chu Xuan thought of the experience of the last time he sparred, and suddenly felt pain all over his body.

So on the way back, he was extraordinarily honest.

The two of them hurried to the foot of the mountain, mounted their horses, and returned to the city.

"Let's go to King Qin's Mansion first."

Chu Xuan didn't dare to refute, and honestly followed him back to the Qin Palace.

After entering, Chu Yan suddenly said, "This king and you haven't been in conversation for a few days?" Let's have a look at it today and see if you can slack off in practicing martial arts. ”

Chu Xuan became anxious when he heard this: "Brother, I have been practicing martial arts diligently recently, and I haven't slacked off at all, really!" You trust me! ”

If he really learns from Chu Yan, will he still be good?

As soon as Chu Yan heard this, his face sank: "If you don't learn, how can this king know if you are lying?" Go change your clothes and talk later. ”

Chu Xuan instantly had the urge to cry, who did he provoke!

Obviously, he has been very honest recently, but the second brother still bullies him!

Chu Yan saw that his face was full of reluctance, so he said, "If you make progress, this king will give you a gift." ”

As soon as these words came out, Chu Xuan, who was still crying and sad just now, instantly lit up his eyes, and he asked excitedly, "How is this embarrassing?" You're my brother, how can you break the bank? However, what are you going to give, brother? If it's too precious, won't my brother deserve it? ”

Chu Yan felt ashamed when he looked at his insincere stupid look.

But he still said: "Cleansing the Myelin Pill, have you heard of it?" ”

"What...... What the? Wash...... Washing the myelin? Chu Xuan's eyes widened in shock, "Brother, are you...... You're not kidding me, are you? Washing the myelin? Is there such a thing in the world? It's not a random name, is it? ”

When Chu Yan heard this, his face instantly darkened: "If you don't want it, then forget it!" ”

Chu Xuan saw that he was angry, and his mind came alive.

He looked at Chu Yan and felt that the marrow cleansing pill in his mouth seemed to be real, but thinking of the records in the book and the legends he had heard, Chu Xuan didn't dare to believe it.

He has always regarded this thing as a myth, and he doesn't believe that this thing really exists in the world, and thinks that it was made up by his predecessors.

But Chu Yan's appearance didn't look like he was lying.

Is there really a marrow cleansing pill?

No, no, no, it can't be true.

His brother must have been deceived, right?

What else is the old fairy, it sounds like a liar.

No, the little uncle's face has indeed been cured, so that old fairy shouldn't be a liar, right?

Could it be that the old immortal also gave the second brother a myelin cleansing pill?

Thinking of this possibility, Chu Xuan was excited, he looked at Chu Yan with burning eyes, and asked with a blank eye: "Brother, the marrow cleansing pill you said was also given by the old immortal?" Have you tried it with someone? Is it really the legendary pill of marrow washing? ”

Also, do you really want to give it to him?

Oh my God, he knew that the second brother was really his own brother!

The more Chu Xuan thought about it, the more excited he became, his face was full of smirks, and Chu Yan was disgusted when he saw it.

Chu Yan said coldly: "If you don't believe it, you can don't want it, anyway, this thing is not easy to come by, and this king doesn't have much in his hands." ”

Chu Xuan suddenly became anxious: "Don't, brother, don't change your mind!" I'm ...... I want it so much! We're brothers! ”

Chu Yan sneered disdainfully: "Heh, why don't you go to change your clothes?" ”

Chu Xuan immediately said, "I'll go change my clothes." ”

At this time, Chu Yan suddenly said again: "Put the peace card first, you don't have to bring it over, this king will collect it for you first." ”

Chu Xuan didn't doubt that he had him, so he directly handed over the brocade box to Chu Yan, and then couldn't wait to run to change clothes.

After Chu Yan got the brocade box, he said to the guards on the side: "You go and watch the King of Jin, and after he changes his clothes, you will accompany him to practice first, and then say that the king has something to do, and I will go to him later." ”

The guards hugged their fists to receive their lives, but their hearts were hot: Is the myelin-washing pill that the prince just said true or false? Could it be that the prince really has the legendary myelin-washing pill?

……

Chu Yan directly took the brocade box and went to find Su Jinli.

When he found Su Jinli, he saw Su Jinli sitting in the study, holding a pen and writing something.

However, the pen in her hand was very strange, it was not a brush, it was a goose feather. The tip of the pen used to write is actually golden, and it looks like metal.

After Chu Yan saw it, he couldn't help but walk over and looked at the pen in Su Jinli's hand curiously.

After looking at it for a while, he asked curiously, "What kind of pen is this?" ”

Su Jinli said while writing: "This is a quill pen, made of goose feathers and gold, and the tip of the pen is relatively hard. ”

In fact, to make a quill pen, you can directly cut the feather tube of the goose feather as the nib.

But Su Jinli is a princess anyway, where can she be so wronged by herself?

So she made a nib out of gold, and there was a knot of pen barrel attached to the nib, which could be attached to the feather tube of goose feathers.

It looks both aesthetically pleasing and edible.

Since the advent of pencils, there have been a lot of hard papers on the market, which are suitable for pencil writing.

She had her own paper mill, and without her command, the craftsmen of the paper mill made a batch of fine cardboard.

After Su Jinli read it, she felt that it was too troublesome to write with a pencil, so she made a quill pen.

There are no rubber trees yet, and there are no hoses for filling ink, so pens will have to wait.

Instead, the quills can be used first.

After finishing speaking, Su Jinli suddenly noticed something and looked at the brocade box in Chu Yan's hand.
