Datang: An eight-year-old master of the bar, he gave everyone a blow at the beginning

Chapter 621 Yuchihuan has successfully made the blackboard

Yu Chihuan beat Changsun Shunde today, so he turned a blind eye to what Changsun Shunde said!
When Changsun Shunde saw Yuchi Huan ignoring him, he said angrily: "Young Prime Minister Yuchi, why are you smearing the bed board?"

Yu Chihuan said angrily: "Changsun Shunde, I'm making a blackboard for teaching now, so don't come and disturb me!"

"Young Prime Minister Yuchi, what is a blackboard? Is this a bed board that the old man borrowed from the harem?"

Changsun Shunde was speechless!

"Ah...Eldest Sun Shunde, so, where did you borrow this board from the Empress?"

Yu Chihuan was taken aback by what Elder Sun Shunde said!
In the entire Chang'an City, only two people can hold Yuchihuan down!
One of them is Li Er!
The other person is the eldest grandson queen who is the mother of the world.

Seeing Yuchi Huan's expression changed drastically, Changsun Shunde thought that Yuchi Huan was afraid, and he said in a snarky voice: "Prime Minister Yuchi, this bed board was used by His Royal Highness the Crown Prince in the palace before, and no one can borrow it except this old man!"

Yuchihuan breathed a sigh of relief: "I see, it seems that I should use it to make a blackboard!"

Originally, Yu Chihuan thought that the plank was lent to Changsun Shunde by Empress Changsun!
Yu Chihuan must give Empress Changsun face!
But the eldest grandson Shunde blew himself up so quickly, the plank was lent to him by Prince Li Chengqian of the Eastern Palace!

Yuchihuan didn't like Li Chengqian, the crown prince of the East Palace, so he directly ignored his eldest grandson Shunde.

Changsun Shunde was stunned, he didn't expect Yuchihuan to ignore him again.

"Did the old man say something wrong?"

Changsun Shunde will review himself immediately!
Yu Chihuan ignored Chang Sun Shunde, who continued to make blackboards.

In order to let the ink on the wooden board dry as soon as possible, Yu Chihuan even took it to dry next to the stove!
After a stick of incense, the blackboard made by Yuchihuan was finally completed.

So Yuchihuan immediately ordered someone to erect the blackboard, and then he used white chalk to write on the blackboard!

In a blink of an eye, Yu Chihuan wrote the first hundred lines of the "San Zi Jing" on the blackboard.

"In the beginning of human beings, nature is inherently good..."

When Yu Chihuan was writing, he still recited the "Three Character Classic" silently!
The officials of the Ministry of Education saw Yu Chihuan writing on the blackboard, and the handwriting was clear!

They were all shocked!

But what makes everyone most curious is the white chalk used by Yuchihuan!
Everyone only knew to write with ink!
Yu Chihuan used chalk to write, which can be said to have shattered everyone's three views!
Sun Shunde, the head of Zhongshu Ling, was dumbfounded and said, "Prime Minister Yuchi, what's the matter with your pen? Why can you write on a wooden board?"

Yu Chihuan said with a smile on his face: "Eldest Sun Shunde, this is called chalk, and it can be used for teaching!"

After finishing speaking, Yu Chihuan picked up a towel and wiped the writing on the blackboard.

The next moment, Yu Chihuan wiped the handwriting all over the blackboard clean.

And since the chalk dust doesn't stick to your hands, it doesn't even float up!

This surprised and delighted Yuchihuan!
"It seems that what the dog system said is true!"

Yuchihuan became more and more satisfied with the special skills of chalk by using chalk
But Yuchihuan was in good health, so he didn't feel the physical strengthening effect of chalk!

Yu Chihuan erased the "Three Character Classic" on the blackboard and started writing "The Analects" again!
In a short while, the first few hundred words of "The Analects of Confucius" were written on the blackboard.

Yuchihuan's act of writing, erasing and continuing to write has attracted everyone's attention!

The official of Zhongshu Province has a look of hell!
They didn't expect that the chalk and blackboard in Yuchihuan's hands could be reused!
"hiss……"

The eldest Sun Shunde also gasped, he was surprised and delighted and said: "Little Chancellor Yuchi, this thing is beneficial to the country and the people, it can be played to His Majesty, His Majesty will definitely reward you!"

Yu Chihuan nodded and said yes: "Changsun Shunde, please help me start the pen and play Your Majesty!"

"Little Chancellor Yuchi, this old man will start writing for you!"

Changsun Shunde was surprised and delighted, he immediately took out a pen, ink, paper and inkstone, and told Li Er about it.

If there was something he didn't understand, Changsun Shunde asked Yuchihuan.

Yuchihuan knew everything about his eldest son Shunde and talked about it endlessly!
After writing the memorial, Changsun Shunde showed it to Yuchihuan!
Yu Chihuan confirmed that there was no problem with Changsun Shunde's memorial, so he immediately played Li Er jointly with Changsun Shunde!
Before half a stick of incense is available, the memorials of Yuchihuan and Changsun Shunde will be sent to Ganlu Hall!

Changsun Shunde was worried that the blackboard incident would be leaked, and he also banned officials from other three provinces and six ministries from entering Zhongshu Province!
Yuchihuan breathed a sigh of relief after confirming that there was nothing wrong with the blackboard.

To make a blackboard that is two meters long and one meter wide, it takes about one bottle of ink!
At present, the price of Datang's ink is [-] Wen a bottle!
In addition to the price of the wooden boards, the manufacturing cost of a two-meter-long and one-meter-wide blackboard is less than [-] yuan!
If you use the wall to make blackboards like later generations, you can save even the cost of wooden boards.

But later generations of classroom blackboards used some sleek construction materials.

Yuchihuan didn't know if these building materials were expensive!
If it is not possible, Yuchihuan decided to use lime to plaster the wall!

Then make chalkboards on the lime walls!
After making up his mind, Yuchihuan was in a great mood!

……

Tai Chi Palace, Ganlu Palace!
In the morning, Li Er was diligently correcting the memorial in the imperial study!
The memorial of Yuchihuan and Changsun Shunde was then sent to the desk of Li Er's case by Xiao Huangmen.

Li Er picked up Yuchihuan's memorial and looked at it with relish.

When Li Er read Yuchihuan's memorial, he was dumbfounded and said, "I never thought that little Yuchi would develop a reusable blackboard and chalk!"

"Your Majesty, what is a blackboard?"

The prince frowned and asked Li Erdao!
Li Er smiled all over his face, and said: "Big companion, little Yuchi used ink to blacken the bed board where the elder Sun Shunde slept, so I taught the blackboard!"

Eunuch Wang shook his head and smiled wryly, "I didn't expect Xiao Yuchi to be so naughty!"

Li Er disagreed and said: "Big Companion, Eldest Sun Shunde thinks highly of the blackboard, I want to go and see what's going on!"

The prince admonished: "Your Majesty, since you want to see the blackboard, why not order Little Yuchi to bring the blackboard to the imperial study?"

"It's true!"

Li Er nodded in approval and said: "Come on, immediately order Zhongshuling Yuchihuan to bring the blackboard and chalk to the Ganlu Hall to see me!"

"Slaves follow orders!"

The prince did not dare to neglect, and he immediately arranged for the eunuch to go to Zhongshu Province to summon Yuchi Huan.

Li Er laughed heartily and said: "I really want to know what the blackboard made by Xiao Yuchi looks like, since it can be used for teaching haha!"

Wang Gonggong echoed: "Your Majesty will know who the blackboard is in a moment!"

After half a stick of incense, the eunuch passed the decree and finally took Yuchi Huan into the Ganlu Hall.

The blackboard made by Yuchihuan was also carried into the imperial study by the imperial army!

When Li Er saw that the blackboard mentioned in the imperial decree was a smeared bed board, he immediately showed disappointment!

Yu Chihuan then also stepped into the imperial study room to face the saint!
