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

Chapter 622 Li Er Orders the Superintendent to Forge a Blackboard

Seeing Yu Chihuan coming, Li Er finally breathed a sigh of relief!
As for the blackboard placed in the imperial study room, Li Er can't see it for the time being!

"Wei Chen sees His Majesty!"

When Yu Chihuan came in front of Li Er, he immediately bowed his hands and saluted as a courtier!

Li Er waved his hand and said, "Xiao Yuchi, you don't have to be polite!"

"The minister obeys the order!"

Yuchihuan immediately straightened his waist!

Li Er pointed to the one-meter-high and two-meter-long blackboard in front of him, and asked, "Xiao Yuchi, can you tell me how to use this blackboard?"

Yu Chihuan immediately took out a box of chalk from the system space, nodded and said: "Your Majesty, this is the chalk for writing. We need to use chalk to write on the blackboard!"

After finishing speaking, Yu Chihuan took out a white chalk and wrote his name on the blackboard!
In the blink of an eye, Yu Chihuan had written his name on the blackboard!

The handwriting on the blackboard is black and white, clear at a glance!
The most important thing is that writing with chalk is much faster than brush!

Li Er's eyes lit up and said: "Xiao Yuchi, can you give me a piece of chalk?"

"Your Majesty, I can give you a box of chalk!"

Yu Chihuan immediately took out another box of chalk from the system space and placed it in front of Li Er!

Li Er followed suit, immediately opened the chalk box, picked up a piece of chalk and laughed heartily, "I want to try writing with chalk too, haha!"

After finishing speaking, Li Er quickly ran to the blackboard, and carefully wrote his name and Zhenguan year number!

After writing his name, Li Er deliberately took a step back to observe it!
After confirming that there is no problem with his name.

Li Ercai said with great joy, "Xiao Yuchi, I never thought that writing with chalk is so smooth, it's even easier to use than a brush!"

"Your Majesty, brushes have the benefits of brushes, and chalk has the benefits of chalk!"

Yu Chihuan thought for a while before answering Li Er cautiously.

Li Er asked curiously: "Xiao Yuchi, I heard that chalk and blackboard can be reused, can you teach me?"

Yu Chihuan pointed to the writing on the blackboard, and said, "Your Majesty, the writing on the blackboard can be erased, if you don't believe me, try it!"

"Little Yuchi, are you sure you didn't deceive me?"

Li Er was stunned, because he had never seen calligraphy that could be erased!

"Your Majesty, look at what I do, haha!"

After Yu Chihuan finished speaking, he immediately reached out and wiped off his name on the blackboard!

To prove to Li Er, the blackboard can indeed be reused!
Yu Chihuan also deliberately wrote his name in the original position!

Li Er was dumbfounded, and said: "It turns out that the handwriting written with chalk can be erased, so it can indeed be reused!"

After all, Li Er immediately reached out his hand to erase the name he had written!

Then Li Er wrote another line on the blackboard!

Then Li Er wiped off the writing on the blackboard!

After repeating it a dozen times in a row.

Li Erxin said convincingly: "Little Yuchi, I am very satisfied with the blackboard and chalk you invented, can you send the chalk formula to the imperial court?"

"Your Majesty, the formula for chalk is gypsum and water, Wei Chen has already prepared it for you!"

Yu Chihuan then handed the chalk formula he had written to Li Er.

Li Er took the chalk formula, read it carefully, nodded in satisfaction, and said, "It turns out that gypsum is ground into powder and water, cooked and frozen is chalk!"

"Your Majesty is right, that's how chalk is made!"

Yuchihuan immediately echoed Li Er's words!
As for the principle of making the blackboard, Li Er already knew it!
So there is no need for Yuchihuan to tell Li Er repeatedly!

Li Er then handed the chalk formula to Wang Gonggong: "Big Companion, pass on my will and order the supervisor to make chalk and blackboards for use in the Tang Academy!"

"The slaves obey the orders!"

The prince didn't dare to neglect, he took the chalk formula from Li's second hand, and immediately left the imperial study in a hurry!
Eunuch Wang already knew how the blackboard was made, so there was no need to ask Yuchihuan!
Li Er was full of praise, and said: "Xiao Yuchi, you did a good job this time, I am very satisfied!"

"Thank you, Your Majesty, for your reward!"

Yu Chihuan responded to Li Er with a smile on his face.

Li Er waved his hand and said, "Little Yuchi, you step back!"

"The minister obeys the order!"

If Yu Chihuan was granted an amnesty, he would leave the imperial study immediately.

Li Er had no intention of returning that blackboard to Yu Chihuan!
After Li Er sent Yu Chihuan away, he continued to use chalk to write on the blackboard in the imperial study.

This time what Li Er wrote was not his own name, but Wang Xizhi's "Lanting Preface"!
As a fan of Feibaiti, Li Er likes Wang Xizhi's handwriting very much!
The originator of Feibai is Cai Yong, a great Confucian in the Eastern Han Dynasty!

In a moment, "Orchid Pavilion Preface" was finished!
Li Er nodded in satisfaction and said: "The blackboard and chalk invented by Xiao Yuchi are really easy to use. This is also a happy event worth celebrating for Confucian scholars in the Tang Dynasty!"

The biggest expense of Hongwenguan and Guozijian is paper and pen!
Now that Yuchihuan invented the chalk and blackboard, it can be regarded as helping Li Er to relieve his worries!
Li Er then sat down to correct the memorial again!
After half a stick of incense, the prince finally left and returned.

"Your Majesty, the master craftsman Yan Liben has already taken over the task of making blackboards and chalks!"

Eunuch Wang immediately reported the situation to Li Er.

Li Er nodded and said in agreement: "Big companion, you can go and tell Liu Zhenghui, Shangshu of the Ministry of Household Affairs, these chalks and blackboards will be distributed to all states and counties of Datang for free!"

"The slaves obey the orders!"

Wang Gonggong left the imperial study room again to convey Li Er's will.

Li Er once again devoted himself to the work of correcting the memorial!

……

Yu Chihuan got busy when he returned to Zhongshu Province!
At noon, it was time for officials from the three provinces and six ministries to be on duty!
Yu Chihuan left the Ministry of Education, and was going to the Royal Academy to talk to Wu Meiniang about making chalk and blackboards!
This time Yuchihuan didn't go home for lunch!
Even passing by the door of the house, Yu Chihuan didn't get out of the car, but went directly to Shanglinyuan!
An hour later, Yu Chihuan finally arrived at the Royal Academy!
The recruitment of the Royal College is still in progress.

Some Guozijian students are carrying rice buckets and vegetable bowls to distribute meals to those boys who take the entrance exam!
The Royal Academy provides free meals for all children!

Even if they are not formal students of the Royal Academy, they can still receive delicious meals!

Yuchi Huan also received a meal along the way and ate it with relish.

The meals at the Royal Academy have a lot of meat and oil, so they taste very good.

Yuchihuan went to Gewu College to find Wu Meiniang after he had eaten and drank enough.

At this very moment, Wu Meiniang is also having lunch!
When Wu Meiniang saw Yu Chihuan's figure, she was startled and said, "Teacher, why did you come to inspect the Royal Academy again today?"

"Meiniang, I came to the Royal Academy to give you a big gift!"

After Yu Chihuan finished speaking, he immediately handed the prepared box of chalk to Wu Meiniang.

Wu Meiniang took a box of chalk and asked curiously, "Teacher, what are these?"

"Meiniang, this is called chalk, it's for writing haha!"

After finishing speaking, Yu Chihuan immediately took out a piece of chalk and began to scribble on the ground.
