Compared to the time when Lu Sanlang got married, the Lu family's wedding was more lively. From the beginning, the house was packed with guests. There were eighty tables set up under the wedding tents that had been set up in various courtyards. Even though it was still early in the morning, the laughter and joy could be heard from far away in the Lu family.
Among the guests were Lu Wan's former colleagues, superiors, and subordinates - most of his colleagues were still in their positions, and some of his former superiors held lower positions than before his retirement, and several of his former subordinates had become high-ranking officials such as assistant ministers or even deputy censors-in-chief - there were also various relatives of the Lu family, and even Lu Wan's classmates in the imperial examinations, classmates of Lu Dalang and Lu Erlang, and so on.
However, the largest group of guests were not these high-ranking officials, but Lu Sanlang’s classmates from Jiuzhang Hall.
There were dozens of these "mentors" who were wearing the same formal clothes they had worn when they went to the East Palace to pay homage to the Crown Prince that day. They could be recognized at a glance because they were dressed in uniform and looked energetic. They came in groups of three or five or occasionally alone. The young ones did not like to talk loudly like their peers, and the older ones did not become depressed because of their lack of career achievements like their peers.
Obviously most of them were of humble origins, but as bridesmaids they were very polite in their dealings with others. They were not arrogant, but not overly humble either. They could remain calm even when facing some young masters from aristocratic families. Even some young masters who were dark-minded and wanted to show off their family background would lose their temper when someone inadvertently said something about His Royal Highness the Crown Prince.
Apart from those guys in Banshan Hall who didn't know how to appreciate their fortune, who else could be like the students in Jiuzhang Hall and be able to be classmates with the Crown Prince who had just entered the East Palace? The most important thing was that no one thought that the Third Prince had the potential to be a Crown Prince!
However, these mentors, who seem to behave well at first glance, have only one problem.
That is, when they were not helping the Lu family to entertain guests, they would often get together in groups of three or five and concentrate on discussing things that others could not understand, or even say were incomprehensible. For example, when several young masters of noble families who knew Ji Jiu in the past saw him talking to several tutors, they quietly approached and heard such a conversation.
"You mean the sine formula you heard from the senior student last time? Oh, I heard Senior Brother Lu mention it." Ji Jiu was already very accustomed to calling Lu Sanlang Senior Brother Lu, as if this way he could regard him as his role model. "Well, although the volume of "New Mathematics" on trigonometric functions is already on the market, it is indeed difficult to learn by yourself... a/sin∠A=b/sin∠B=c/sin∠C=2R?"
"What is this R? R is the radius of the circumcircle of a triangle. As for how to understand the circumcircle, I specifically asked a teacher. Draw a perpendicular bisector along the three sides of a triangle, then extend the perpendicular bisector to a point, and then use that point as the center of the circle and the distance from the point to any vertex of the triangle as the radius to draw a circle. This circle is the circumcircle, and this radius is R..."
Several young masters from aristocratic families looked at each other and saw that Ji Jiu hadn't noticed their arrival at all. Instead, he was concentrating on explaining something that was completely confusing to them. The leader took a step back and then lowered his voice and said, "Don't you think Ji Jiu looks like he's possessed?"
