"Since ancient times, the folk have had many miraculous remedies. This is absolutely true. Xiaohang, it seems that your ancestors were not just ordinary barefoot doctors." Qin Yongjian, like a toddler just learning to walk, was supported by Qin Shiyu and Shuai Yu as he enthusiastically walked back and forth in the room. Upon hearing Su Hang's words, he immediately turned around and said.
Su Hang, hearing this, felt a bit embarrassed. He was not clear about his ancestors, but this ointment was definitely not a so-called family secret recipe.
"Pity the formula has been lost, only a few sheets remain." Su Hang shook his head.
Qin Yongjian, upon hearing this, also sighed, "Indeed, the wisdom of our ancestors is profound. Unfortunately, many of these miraculous wisdoms have been lost in the long river of history. What a pity. Xiaohang, you must take good care of the ointment in your hands. Perhaps in the future, with more advanced technology, we can restore the formula."
Su Hang could only nod in agreement, but in his heart, he did not think much of it. With the system, he believed there would be many more things like this, or even better.
...
That evening, Qin Yongjian insisted on keeping Su Hang for dinner. Unable to resist the family's enthusiasm, Su Hang stayed and even demonstrated his astonishing appetite, which made Qin Yongjian exclaim in amazement.
By the time Su Hang left that evening, Qin Yongjian was already able to walk without support. The ointment's effect lasted for three days, and from the way it was working, he would likely be fully recovered in less than two days. Qin Yongjian even came downstairs to see Su Hang off, as Su Hang not only cured his foot but also gave him a new lease on life.

Tuesday, professional class.
The professional class teacher was a balding old man in his sixties named Chu Aiguo, who had been rehired after retirement. This old man's lectures were extremely dull. He wore reading glasses and just lectured on the podium, leaving it to the students to listen or not. He never took attendance and never got angry. At least, this had been the case for the two months since the start of the semester. It seemed as if he lived in his own world, and his classes were undoubtedly boring, but also the happiest, because many students skipped them.
The large lecture hall, with over a hundred seats, was shared by three classes, yet only about thirty people were seated, and some of them were dozing off in the back rows.
There was a legend in the class: if someone had trouble sleeping, they should attend Chu Aiguo's class, as it was a sure cure for insomnia.
Today's lecture was on mechanical drawing, but it was all basic lines and symbols. A cross-section of a rivet was drawn on the blackboard, and Old Man Chu stood on the podium, explaining in his low, hoarse voice without any interaction or questions, as if reading from a textbook. However, the students who paid attention would notice that much of what he said was not in the textbook.
"Bro, why are you listening so intently?"
Shuai Yu dozed off and woke up groggily, looking at the clock to see that only five minutes had passed. Turning to look at Su Hang, he saw him staring intently at the podium, a sight he had never seen before. Could this guy be trying to become a top student?
Su Hang, hearing this, quickly turned his gaze from the podium, inwardly marveling at the difficulty. He had wanted to test his natural talent without the system's help, but after only five minutes of serious listening, he could hardly keep his eyes open. It was just as the seniors had said; this old man's lectures were like a book of heaven, and out of all the students in the room, who knew how many could endure it. Su Hang couldn't help but feel sleepy.
Chu Aiguo was not only a distinguished teacher but also a senior mechanical engineer. When Su Hang was at Ye Xueyi's house, Deng Wentao had spoken highly of this person, suggesting that if Su Hang had any questions in his major, he should consult Chu Aiguo, as it would be very beneficial.
This old man had a unique teaching method, as Deng Wentao had mentioned, a typical genius-style education. His lectures always went beyond the textbook, and without talent or interest, it was hard to gain much from his classes. However, those who listened carefully and could understand and absorb the content would perform outstandingly in their field. Despite his poor lecturing style, many elites had come from his classes.
Having made a bet with Deng Wentao, Su Hang naturally wanted to win this competition. Deng Wentao had given him only two months, and he believed that Deng Wentao's student, Qian Feng, would not need two months to fix the supercharged engine's defect. To win, he had to get ahead of Qian Feng.
However, Su Hang's knowledge of mechanical engineering was zero, and two months was not enough to catch up. Listening to such a boring class was worse than being killed.
It was more convenient to extract the knowledge directly. A top student should act like one. Su Hang scanned Chu Aiguo with the system, and the value of his mechanical engineering knowledge was 100 energy points, indicating that Chu Aiguo's expertise in mechanics was on par with Liu Guifen's in English.
Before Su Hang could extract Chu Aiguo's specialty, Shuai Yu suddenly interrupted him. Reluctantly, he scanned Chu Aiguo's information and planned to extract it later.
Turning his gaze from the podium to Shuai Yu, he asked, "How is your grandfather's leg?"
Mentioning this, Shuai Yu immediately perked up, "You won't believe it, but your ointment is truly miraculous. My grandfather's leg, which was so bad before, was completely healed yesterday. He can run and jump, better than ever. You wouldn't know, but last night, I had to peel dead skin off his leg all night. The skin was so smooth, like a young girl's. Today, my uncle and aunt took him to the hospital for a recheck. My uncle said he should find a time to invite you to our home and thank you properly."
"There's no need for such formality. As long as the ointment works." Su Hang shook his head, not really caring about the thanks. Shuai Yu and Qin Shiyu were his friends, and helping them was no big deal. Moreover, this ointment's value was truly remarkable, almost like a divine formula.
Unfortunately, only three sheets remain, and he must keep them well. Even if he doesn't need them, they could fetch a good price in the future.
