"At such a young age, Childe was able to have such a smart mind and come up with a way to replace the power of humans and animals with the power of water...... It's just that the son is in a high position, why is he so concerned about this trivial matter of grinding rice noodles? ”

After learning what Liu Chan and Pang Tong did this time, while he was surprised by Liu Chan's ingenuity, Huang Chengyan was puzzled by his dignified son, but he was concerned about trivial things such as rice grinding noodles.

"Old man, although it is a trivial matter, it is related to the people's livelihood. If we can reduce the burden on the people in this way, so that they can have more energy to cultivate or do other things, wouldn't it be a good thing to kill multiple birds with one stone......"

In the face of Huang Chengyan's inquiry with the meaning of the school examination, Liu Chan was not timid at all, and immediately talked eloquently from the aspect of people's livelihood and people's strength.

"Since the Yellow Turban Rebellion, under the endless war, the household registration in the world has been halved and the people's power has withered. The kid also wants to save manpower with this machine technique, and at the same time reduce the burden of the people, and do something for the recovery of people's strength! ”

In the end, Liu Chan used the matter of the water-powered mill to add a halo of compassion for the people's livelihood to himself. However, he did not mention his original intention of building this water-powered mill, but only to increase the output of the paper mill in the future.

It's just that he doesn't mention it, but it doesn't mean that others don't mention it.

No, just as Liu Chan's words fell, Pang Tong on the side had already opened his mouth to make a note for him.

"Shibo, Gongzi made this hydraulic mill in order to increase the output of the paper mill, in order to make it more convenient and easy to use paper writing ...... the world."

Under the introduction of Pang Tong, including Huang Yueying, the 'engineer', the Huang family father and daughter soon learned the real reason why Liu Chan wanted this hydraulic mill.

"So, Childe has already made a paper that can completely replace the slips and silk?"

After listening to Pang Tong's introduction, the Huang family's father and daughter couldn't help but look at Liu Chan with a shocked face.

You must know that since Cai Lun improved papermaking, although its paper can barely be used for writing, but because of its fragility, it has led to the real mainstream writing plant, and it has been a cumbersome simple and expensive silk silk until now, but paper has not really become popular.

"Exactly! The picture of the hydraulic mill that Madame saw was drawn on this new paper, not the silk or silk silk of the past......"

Seeing the surprised expressions of the Huang family's father and daughter, Liu Chan smiled and pointed to the picture of the hydraulic mill that Huang Yueying had placed on the table.

It turned out that Huang Yueying, who had been thinking about the hydraulic mill before, did not notice the particularity of the material of this picture.

"This paper is as thin as a cicada's wings and evenly thick, smooth as jade and full of toughness...... It has the advantages of both simplicity and silk, but there is no disadvantage of both, it is really the best product of writing, and the son is really a genius! ”

When they learned that the drawings of this hydraulic mill were drawn on new paper, after some observation, the father and daughter of the Huang family gave a very similar evaluation to Pang Tong at the beginning.

Not only that, but because of this parchment paper, the duo's impression and evaluation of Liu Chan has also reached a higher level.

"The two of you are too famous, this is just a little gossip! The kid just wants to make a profit from this paper, so that the people of Jingzhou and the world can have more books to read......"

Because of Huang Chengyan's sudden appearance, Liu Chan, who had a temporary intention to 'abduct' the father-in-law of Zhuge God, quickly lost no time in starting to 'act' at this moment.

"Let more people have books to read? Childe means ......"

Hearing Wang Bing's extremely noble ideal, Huang Chengyan couldn't help but be shocked.

"Shibo, what Childe said is true! Previously, Childe had ...... with Tongyan"

After glancing meaningfully at Liu Chan, Pang Tong, who understood it, immediately introduced to Huang Chengyan for him the previous 'prescription' prescribed by Liu Chan, and the use of paper to open a school in Jingzhou, and then open a department and other things.

……

"The ambition of the son is like this rolling river, which is very comparable!"

After a long time, after learning from Pang Tong about Liu Chan's 'prescription' for treating the root of the Han disease, Huang Chengyan couldn't help but praise it again.

"The rivers and seas are all gathered by streams, although the kid has the ambition to make the people of the world peaceful and can study and study, but he is alone, but he is not enough!"

With Huang Chengyan's praise, Liu Chan immediately hit the snake with the stick, looked at the other party with a look of anticipation, and almost said the words to let the other party take refuge.

"Haha, the old man has always been used to idle clouds and wild cranes, and he is old, but he wants to live up to his son's good intentions!"

In the face of Liu Chan's naked solicitation, Huang Chengyan naturally knew the meaning of this.

It's just that as the contemporary head of the Nanyang Huang family, even Liu Bei couldn't let him out, let alone Liu Chan, a nameless and shareless 'young master'?

Therefore, without thinking about it, Huang Chengyan directly refused.

"The old gentleman misunderstood, the kid just wanted to implore the old gentleman to occasionally give lectures to the students in the academy in Jingzhou in his spare time in the future to solve his doubts......

Seeing that even with Pang Tong's assistance, the old guy still refused to take the bait, Liu Chan could only retreat to the second, planning to make the other party a 'volunteer teacher' who couldn't even get a salary, and then slowly grind it later.

"Uh, lecturing students? Old man Rong thinks about it......"

Seeing that Liu Chan never raised the matter of officials, but just moved out of the matter of lecturing to Jingzhou students in the future, Huang Chengyan was a little difficult to refuse.

As the so-called three immortals of virtue, meritorious service, and words, as a generation of celebrities, who doesn't want their doctrine to be known and accepted by more people?

Therefore, after receiving Liu Chan's invitation, Huang Chengyan couldn't help but feel a little moved at this moment, even if he was idle Yunye Crane.

It's just that Liu Chan's attitude changed too quickly. So under the instinctive reaction, Huang Chengyan hesitated a little again.

"Could it be that Mr. Fei is the same as the boy, he doesn't like to add green onion and ginger seasoning to this tea?"

Seeing that Huang Chengyan, who was hesitant, took a sip of the tea in front of him, then frowned and put it down, and instead picked up the wine gourd hanging on his waist, Liu Chan immediately continued to talk without words.

"The old man likes the fragrance of this tea, but he doesn't like the bitter taste. This adds green onion and ginger seasoning, although it is not bitter, but it also destroys the aroma of the tea, it is really difficult to choose, haha! ”

Hearing Liu Chan's inquiry, Huang Chengyan also immediately replied meaningfully.

"Haha, don't worry, the old gentleman can rest assured, this matter of lecturing to the students is as the old gentleman wishes, and there is no half of the constraint!"

Hearing the sound and knowing the other party's worries, Liu Chan hurriedly opened his mouth and promised.

"In addition, let the old gentleman know that the kid just knows a new method of making tea, which can not only retain the fragrance of tea, but also make the tea become sweet and delicious without adding onion and ginger seasoning, and have a long aftertaste!"
