After the upgrading of Yizhou's post station system was completed, Liu Ba immediately sent a letter to Lin Chuan to report the situation.

Hanzhong County, Hanzhong Marquis Mansion.

Lin Chuan was listening to the report of Chen Yuan, the head of the R&D center.

"Lord Hou of Hanzhong, the glass mirror developed by the R&D center that you explained before has been successfully manufactured!"

Chen Yuan said to Lin Chuan with an excited face.

After Liu Ba went to Yizhou to preside over the construction of the post station, Lin Chuan had plenty of leisure time.

Lin Chuan has great trust in Liu Ba's ability, and Liu Ba also has Xiahou Dun, who is sitting in Yizhou, to help, so Lin Chuan is not worried about the construction of Yizhou's post station at all.

In his spare time, Lin Chuan, in addition to going to Hanzhong Vocational Training School once a week to give students a science class, Lin Chuan researched the system lottery in the courtyard of Fuzhong, or went to the surrounding areas of Hanzhong to relax.

It's a pity that luck was used to extract the textbooks before, and the large amount of prestige brought by Hanzhong Vocational Training School after the opening of the school was squandered by Lin Chuan again, and the remaining half Lin Chuan didn't dare to move again.

Although he didn't draw anything good, an unintentional performance by Cao Jie inspired Lin Chuan.

Cao Jie, who is now in his twentieth year, has begun to study how to dress himself because he has not yet won Lin Chuan.

So Cao Jie often carried a small bronze mirror with him, and every time he went to Lin Chuan's study, he first took out the bronze mirror to check whether his makeup was flawed.

Once Lin Chuan happened to be accidentally discovered, Cao Jie secretly inspected his makeup in front of the bronze mirror at the door of the study, and Lin Chuan suddenly remembered that there was no mercury mirror at this time!

Cao Jie checked his makeup outside the door and found that there were no flaws, so he entered the study and asked Lin Chuan to eat.

Lin Chuan looked at the picturesque Cao Jie and said that he wanted to surprise her.

Then Lin Chuan came to the R&D center, found Chen Yuan, and handed him the production method of the mercury mirror, and told him that the mercury mirror was not only a good commodity, but also a gift to Cao Jie, and it should be successfully developed as soon as possible.

When Chen Yuan heard that he still wanted to give Cao Jie a gift, he immediately called the three most ingenious masters in the production base to jointly develop mercury mirrors.

When developing the mercury mirror, Chen Yuan also specially told the three masters that this mercury mirror was a gift from the Hou of Hanzhong to Miss Cao.

The three masters are not only ingenious, they have already started a family, they are also proficient in human affairs, Miss Cao is not only the most beloved daughter of Lord Wei, but also a big figure who will become the Marquis of Hanzhong in the future.

So everyone put the most effort into developing mercury mirrors.

Now mercury is not rare, and glass also has its own glass production base, although it is not possible to produce large pieces of glass, it is not a big problem to make a mirror-sized glass.

The only problem to be solved is the flatness of the glass mirror and the thickness of the mercury.

Under the continuous experiments of the three masters and Chen Yuan, the mercury mirror was finally developed!

Chen Yuan immediately came to the Hanzhong Marquis Mansion with this mercury mirror, and reported the good news to Lin Chuan in the study.

Lin Chuan was also very happy when he heard that the mercury mirror was successfully developed.

After Cao Jie heard Lin Chuan say that he wanted to give himself a surprise, he was very happy every day, and he couldn't help but ask himself when he would receive this surprise, and now he could finally send this surprise to Cao Jie.

"The glass mirror is finally finished? Did you bring a sample? ”

Lin Chuan happily asked Chen Yuan, and Chen Yuan carefully took out the tight mercury mirror wrapped in a piece of silk from his arms.

Lin Chuan took the carefully wrapped mercury mirror, and after slowly opening the wrapped silk, he saw his handsome face very clearly.

Then Lin Chuan turned the mercury mirror over again, and found that the mirror was inlaid on a whole piece of gold, and the gold was also carved with exquisite patterns, and a piece of transparent jadeite was inlaid in the center.

After holding the entire mirror in his hand and carefully examining it for a moment, Lin Chuan showed a very satisfied smile.

"Master Chen, this glass mirror is very exquisitely made, Miss Cao will definitely be very satisfied!"

Lin Chuan smiled at Chen Yuan.

"Miss Cao is satisfied, hahaha."

After being praised by Lin Chuan, Chen Yuan was also very happy and couldn't help laughing.

"This time I worked hard for Master Chen and those three masters, and Benhou will give you a reward of one hundred taels of silver each! After going back, seize the time to mass production, and the next blockbuster product launched by the Hanzhong Chamber of Commerce is this glass mirror. ”

After Lin Chuan set a reward for Chen Yuan and the three masters, he told Chen Yuan again.

Chen Yuan originally thought that this time, with the carefully made glass mirror, it would be a great achievement to make Lord Hou of Hanzhong please Miss Cao, but he didn't expect that there would be a reward of one hundred taels of silver, so he couldn't help but be even happier.

"Thank you Lord Hanzhong for the reward, I will go back to the production base and let the craftsmen hurry up for mass production!"

Chen Yuan, who had been rewarded, knew that Lin Chuan was in a hurry to give the glass mirror to Cao Jie, and after thanking Lin Chuan for the reward, he left directly.

After Chen Yuan left, Lin Chuan took the glass mirror to find Cao Jie.

"Miss Cao, I have brought the surprise you have in mind."

As soon as he saw Cao Jie, Lin Chuan said to her with a smile.

Cao Jie learned that the surprise had finally arrived, and said very happily:

"Where's the surprise? Let people see it! ”

Lin Chuan did not continue to sell Guanzi, and took out the glass mirror from his arms and put it in Cao Jie's hand.

Cao Jie took the glass mirror and looked at it, and his delicate face was reflected very clearly in the mirror, and even the fine fluff on his face was clearly visible, and he immediately fell in love with this glass mirror.

Then Cao Jie flipped the glass mirror over, and the back of the glass mirror was exquisitely ornamented and the thumb-sized crystal clear jade made Cao Jie's eyes shine!

"Mr. Lin, I really like this surprise festival!"

Cao Jie said to Lin Chuan very happily, and Lin Chuan also smiled when he heard this.

"Jie'er also wants to surprise Mr. Lin!"

Lin Chuan couldn't help but be stunned when he heard that he still had a surprise.

Just when Lin Chuan was stunned, Cao Jie came to Lin Chuan, stood on tiptoe and pecked Lin Chuan's cheek quickly, and then quickly ran back to his boudoir.

Lin Chuan was caught off guard by Cao Jie's sudden attack, and subconsciously touched the kissed place with his hand, and then showed a helpless smile.

After returning to the study, Lin Chuan was still thinking about Cao Jie's bold performance.

At this moment, a guard sent a letter from Liu Ba, and Lin Chuan calmed down to read Liu Ba's letter.

After reading Liu Ba's letter, Lin Chuan knew that the transformation and construction of the post station in Yizhou had been completed, and now it had begun to play a role, and the production base in Yizhou was about to start at full capacity!

"It's a double happiness today, hahaha!"

Lin Chuan laughed out loud in the study.
