Yeah, before they were even complaining that Chu Jin stole their credit.

Now that Third Master Zhou has benefited, naturally, those previous words don’t hold water, and they can’t help but feel ashamed.

"Since you have things to do, Third Master, go ahead. I don’t need you to entertain me, I just stopped by to give a gift and leave, so others don’t think you’re easy to bully." Chu Jin laughed heartily.

Third Master Zhou nodded, "Then I must thank you, little brother."

"I’d be happier if you didn’t call me little brother," Chu Jin grinned and pretended to be fierce.

"Since Lord Chu originally asked me to look after you, I announced to others that you’re my little brother. Naturally, what has been said is like water spilled, it can’t be taken back."

"Alright, alright, I don’t want to hear your excuses, go quickly and take care of your business. If anyone bullies you, remember to come to me for help. You should know that in the circles of the capital, no one gives me a hard time now." Chu Jin bragged gleefully.

Third Master Zhou shook his head helplessly; he was almost twice Chu Jin’s age, enough to be his uncle.

Yet everyone knew he associated with Chu Jin frequently. Since he was once a Commoner with no titles, and not yet qualified to converse with Chu Heng, naturally, his status dropped unknowingly.

However, he did not regret it now. At least having a friend in the official circle was a good choice.

Indeed.

The news that Chu Jin visited and had a great conversation with Third Master Zhou soon spread.

After that, fewer people troubled Third Master Zhou.

Once Chu Jin saw the desired effect, he left early.

When he returned to the Chu family estate,

he directly brought in some craftsmen skilled in making colored glaze.

In the days that followed, Chu Jin would either go to the Imperial College to study or return to conduct research.

The Chu family had a quota, and naturally, once he passed the Imperial College’s entrance examination, he could study there.

Although Chu Jin had been at sea for a long time, he mostly stayed on the ship during the journey and naturally did not waste time.

He finished all the books Chu Heng prepared for him, as well as some tests he wrote out. With such a good teacher, if he couldn’t even pass the entrance exam for the Imperial College, he might as well consider himself useless.

After all, the Imperial College’s entrance exams were far simpler than the provincial exams for the first place in the examination or the imperial examination. If he couldn’t pass these, the others were out of the question.

Chu Jin’s life in school was quite ordinary; he didn’t stir up trouble, nor did Ye Muyu or Chu Heng need to worry about him.

When Ye Muyu learned that Chu Jin brought back a telescope,

she specifically instructed people to see if any of these Maritime Merchants brought back eyeglasses.

In ancient times, there were people with nearsightedness, but they often just thought they had an eye condition and would take medicine randomly, sometimes leading to early death because of it.

Not to mention what a huge business opportunity the invention of eyeglasses would be, just looking at who could afford eyeglasses, their families were certainly not poor.

Su Lan was naturally happy to let these people owe her a favor.

Perhaps she was just lucky.

The people Su Lan sent out actually brought back a pair of eyeglasses from outside.

"My lady, this object, the Maritime Merchant said is made of colored glaze, that’s why he brought it back. He thought wearing it could make things that were unclear become clearer, like a miraculous object. But who knew after showing it, many people said they felt dizzy and accused him of being a fraud. So, when our people saw that it looked alike and was made of transparent thin sheets like colored glaze, they bought it."

Gao Yunli was also a bit curious, as he too had tried them on but felt dizzy just like the others.
