In fact, before Qiuqiu came, what kind of weird person Huang Qi was, Li Yi had already told her.

Now after listening to Huang Qi's simple explanation, Qiuqiu understands even more that Huang Qi's home is like a place for inventors to realize their dreams.

He is an investor and one of the avid inventors.

His strength was in the iron furnaces, which produced all sorts of strange iron, chains, balls, and wheels, and he was a bit better than his friends, because he had two apprentices under him.

One of them was his son.

Li Yi and Qiuqiu said that Huang Qi's family originally lived in Los Angeles, and he was the only one who lived in the countryside half a day away from Los Angeles.

After the war broke out at the border pass, his old man and brothers, as well as Yahuan's mother-in-law and servants, a family of fifty or sixty people fled from Los Angeles.

They refused to live in Huang Qi's house in the countryside, they were afraid of death, and as a result, they encountered robbers on the road, and all of them were killed.

Fortunately, Huang Qi's daughter-in-law and children are still with him, and his son, like Huang Qi, is also an invention enthusiast, which is related to the fact that he has been with his father since he was a child.

After visiting Huang Qi's ironware workshop, Qiuqiu went to see the wheelchair again.

The wheelchair has been formed, with a chair body made of solid wood, two large driving wheels underneath, two small iron wheels at the place where the feet are stepped, and an iron rocker hand on the right hand side is installed to control the large iron wheels under the chair.

The man who made it out was frowning, he couldn't figure out what was wrong, obviously he imagined that the shaking hand could control the iron wheel, but the fact was in front of him, what was stuck in the shaking hand, and it couldn't play its role.

Huang Qi explained that the man had already figured out the low-seat cart.

It is the kind of hemiplegic patient who sits on it and can move by touching the ground with one foot, which is suitable for hemiplegic patients to move at home and not lie in bed every day.

In addition, you can also train the muscle strength of the key limbs, so that you will not be paralyzed in bed for a long time, and even half of the hemiplegia will slowly lose consciousness.

The wheelchair he is tinkering with now is specifically for patients with paralysis of the lower limbs.

Qiuqiu smiled and asked, "So, this eldest brother must be a doctor?" ”

The man who tinkered with the wheelchair smiled: "Princess Huiyi, Xiaomin was originally a bone-setting doctor, but due to limited qualifications, he has worshiped the master since he was ten years old, but he has not yet received half of the master's true inheritance.

Xiaomin thought that he couldn't harm others because of his lack of skill, so he left the hospital and wanted to use other ways to help the patient. ”

Qiuqiu clapped his hands and praised him: "No matter what method you use, you can help the patient for the sake of the patient, you are worthy of respect, the wheelchair in your hand, maybe I can help you." ”

The man tinkering with the wheelchair was pleasantly surprised: "Really? Princess Yi, do you still know this? ”

Qiuqiu smiled mysteriously: "Don't you know? I'm also a doctor, and I once thought about making a wheelchair like this for a patient. ”

After a whole day of tossing and turning, Qiuqiu finally reloaded the wheelchair shaker with the bone-setting doctor, and readjusted the position between the two small casters and the two driving wheels.

Qiuqiu personally sat on it to experiment, and the effect was amazing.

It's amazing that it can drive and brake with just a simple swinging device.

The bone-setting doctor shook Qiuqiu to the ground, grateful and admired, you must know that he has been tinkering with this wheelchair for almost a year, and he still hasn't found the key to the problem.

Princess Yi was so smart that after her casual guidance, he suddenly realized it.
