Jin Yuanyuan was secretly delighted to see Su Yue acting crazy. Su Yue was a bully at school, and she especially enjoyed watching Su Yue, who came from the countryside, being bullied! Lin Jin packed up the lunchbox and pulled Su Yue back to the classroom!

She didn't pay attention to Su Yue's matter. She didn't have evening classes today, so she went to find Professor Hu to ask about the Banquet Return Technique. She had already taken pictures of some of the words on the Banquet Return Technique with her camera, and she just needed to show the photos to Professor Hu!

Professor Hu's hotel wasn't far from the school; Lin Jin arrived in just half an hour by bike! Professor Hu's assistant, seeing it was Lin Jin, quickly led her inside. Lin Jin first took Professor Hu's pulse and then asked about his condition over the past few days. Lin Jin then said, "He needs to continue taking the medication for another week. I'll change the medication for him later."

The assistant nodded to indicate that he understood.

Professor Hu looked at Lin Jin with a smile and said, "Dr. Lin, where did you learn such amazing medical skills? It's only been a few days, and my eyes can see clearly again!"

Lin Jin replied with a smile, "Professor Hu, I just happened to be lucky enough to know how to treat your illness!"

Professor Hu then said, "Don't be modest. Look at you, so young yet with such excellent medical skills. It would be a pity if you didn't continue your studies." The school leaders had already spoken to Lin Jin about this when they learned that she could cure Professor Hu! Lin Jin also explained why she didn't continue studying medicine!

Lin Jin had no choice but to explain again, "What the country needs now are people who can build the country. Although studying medicine can help, I prefer the feeling of making money!" Professor Hu, hearing Lin Jin's explanation, didn't know what else to say.

Lin Jin then said, "Professor Hu, I've come today to ask for your help with something!" Professor Hu smiled and nodded, "Dr. Lin, please speak freely. I will do my best to help." Lin Jin took out a photo from her bag and handed it to Professor Hu. "Professor, I happened to see these characters, so I took a picture of them. There are some characters I don't recognize, and I would like to ask you to help me identify them." Professor Hu took the photo and examined it carefully. After a while, he excitedly exclaimed, "These characters look so much like the characters in a tomb we visited before!"

He warmly invited his assistant to come and take a look, and his assistant nodded slightly in agreement, saying, "It really does look like it!"

However, the assistant then seemed to suddenly remember something and asked in confusion, "Dr. Lin, how did you come to have these things?"

Lin Jin's smile vanished instantly, and he replied calmly, "I'm sorry, this is a private matter and it's not convenient for me to disclose it to you."

Seeing this, the assistant quickly explained, "Dr. Lin, please don't mind! We were just too excited and couldn't control our curiosity." Professor Hu, who was standing next to him, also quickly chimed in, "Yes, yes, Xiao Shi is right. We were just too excited to see these things! As you know, when we work in this field and see these ancient objects, we can't help but want to learn more about them and analyze the stories behind them."

Lin Jin nodded understandingly, then changed the subject and asked, "So, Professor Hu, what do you know about these characters?"

Professor Hu took the photo and examined it carefully again. After a long while, he slowly said, "Well, I can probably only recognize a few characters." He then gestured to his assistant to bring a pen and paper. Professor Hu then began to carefully write down the characters on the paper, pointing to those in the photo. After finishing, Professor Hu explained to Lin Jin, "These characters are 'spirit,' 'qi,' and 'secret formula.' Put together, they might be some kind of incantation about spiritual energy. However, the remaining characters are too obscure for me to recognize."

Lin Jin was somewhat disappointed after hearing this, but still politely thanked Professor Hu.

Then he asked: Professor Hu, would you mind telling me about the tomb you just mentioned?
