"Since ancient times, there have been many strange prescriptions, this is not bad at all, Xiaohang, it seems that your ancestors are not as simple as ordinary barefoot doctors. Qin Yongjian was like a doll who had just learned to walk, letting Qin Shiyu and Shuai Yu walk back and forth in the room with great interest, and when he heard Su Hang's words, he immediately turned around and said.

When Su Hang heard this, his heart sweated, he didn't know what the situation was with his ancestors, but this plaster was really not his so-called ancestral secret recipe.

"It's a pity that the prescription is lost, so I left these few sheets. Su Hang shook his head.

When Qin Yongjian heard this, he also sighed, "Yes, the wisdom of our ancients is really broad, but unfortunately, many magical wisdom crystals have been drowned in the long river of history, alas, what a pity, Xiaohang, the plaster in your hand has to be kept, and when the technology is more developed in the future, maybe this formula can be restored." ”

When Su Hang heard this, he had to nod his head and promise, but he didn't think much of it in his heart, there was a system, something like this, or something better, I believe there would be a lot.

......

That night, Su Hang was left by Qin Yongjian to eat, Su Hang couldn't resist the enthusiasm of the family, so he had to stay, and by the way, he performed his amazing amount of food, so that Qin Yongjian saw it, which was really amazing.

When Su Hang left at night, Qin Yongjian was already able to walk on the ground without support, the effect of the dog skin plaster can be managed for three days, depending on the effect of the drug, I am afraid that it will not take two days to recover, Qin Yongjian also went downstairs to send Su Hang, for him, Su Hang not only cured his foot, but also let him regain his life.

Tuesday, professional class.

The teacher of the professional class is a half-old man who thanked the top, in his sixties, named Chu Aiguo, who is retired and rehired, this old man lectures, but it is very boring, with a reading glasses, just talk by himself on the podium, the students in the audience can listen to it, forget it if they can't listen, he doesn't care about it at all.

Never named, never angry, at least, in the past two months of school, this old man seems to live in his own world, taking his class, is undoubtedly boring, but also the happiest, because there are many people skipping class.

There are only about 30 people sitting in the huge lecture hall, hundreds of seats, and students in three classes attending classes together, and some of them are dozing off in the back row.

In the class, there is such a legend that if anyone has a bad sleep, then go to listen to Chu Aiguo's class to cure insomnia, and the effect is really good.

Today's talk is about mechanical drawing, but it is all some entry-level lines, symbols within the things, the blackboard drew a riveted section, the old man Chu stood on the podium, with his low and old voice, self-care explained, no interaction, no questions, as if reading from the book, but the students who listen carefully will find that many of the things that the old man talks about are not in the books.

"Dude, why do you listen so seriously?"

Shuai Yu took a nap, raised his head in a daze, hadn't finished class yet, looked at the time, only five minutes had passed, turned his face to look at Su Hang, and was looking at the podium with two eyes, this situation, but I have never seen it before, does this guy want to break away from the masses of people and change careers to become a scholar?

When Su Hang heard this, he quickly withdrew his gaze from the podium, and secretly said in his heart, he originally wanted to try how much talent he could have without relying on the help of the system, but he only listened carefully for five minutes, and he really couldn't bear it, and his eyelids were fighting.

It's really like what those senior brothers and sisters said, what this old man is talking about is completely from heaven, just like Daozu's preaching, there are so many people in the classroom, I don't know how many can carry it down, anyway, Su Hang can't help but want to sleep.

――

Name: Chu Aiguo

Age: 68 years old

Realm: None.

Extractable Specialty: Mechanical Engineering (Proficient)

――

Chu Aiguo is not only a special teacher, but also a senior mechanical engineer, when Ye Xueyi was at home that day, Deng Wentao had a lot of evaluation of this person, so that if Su Hang does not understand anything in the major, he can consult Chu Aiguo more, and there will be a lot of gains.

This old man Chu, the teaching method is very unique, Deng Wentao mentioned, a typical genius education method, his classes, has always been beyond the scope of textbooks a lot, if there is no talent, or students who are not interested in this, it is difficult to gain anything in his class, but as long as you listen carefully to his class, and can understand and absorb, you will perform very well in the professional field, don't look at the old man's lectures, but from his hands have also come out of many elites.

has made a bet with Deng Wentao, Su Hang naturally wants to win this competition, Deng Wentao only gave him two months, and I believe that Deng Wentao's student Qian Feng will definitely not take two months to repair the defects of the speeding engine, if you want to win, you must be in front of Qian Feng.

However, Su Hang's current reserves of mechanical expertise are completely equal to zero eggs, and in two months, it is definitely not possible to temporarily cram, so it is better to kill him if he listens to such a boring class.

It is still the most convenient to extract directly, and there should be a god of learning, Su Hang called up the system and scanned it, Chu Aiguo's mechanical engineering is worth 100 energy points, that is to say, Chu Aiguo's attainments in mechanics are already not low with Liu Guifen's attainments in English.

But before Su Hang had time to extract Chu Aiguo's expertise, Shuai Yu suddenly planned him, and he had no choice but to sweep down Chu Aiguo's information first, and then extract it when he was free.

His eyes withdrew from the podium and turned to Shuai Yu, "Is your grandfather's leg healed?"

As soon as he talked about this topic, Shuai Yu immediately came to his senses, "Don't say it, your dog skin plaster is really amazing, my grandfather's leg, it was like that before, but it was all right yesterday, he can run and jump, it's better than the original, you don't know, last night, let me tear off the dead skin for him all night, the skin is tender, and the big girl is like, today my uncle and aunt took him to the hospital for a re-examination, my uncle said, I have to find a time to invite you to go home again, and thank you well." ”

"Why be so polite, as long as the plaster is useful. Su Hang shook his head, what is the thanks, he doesn't care very much, Shuai Yu and Qin Shiyu are friends with him, it doesn't matter if they help, and this also makes him know the value of the dog skin plaster, which can definitely be regarded as an immortal prescription.

It's a pity that there are only three left, so you have to keep them, and even if you can't use them in the future, you can sell them for a good price
