The brother and sister had worked together many times before. No matter what length of needle Song Yun wanted, as long as she said it, Ziyi would immediately find it and hand it to her.

Song Yun inserted silver needles into eight acupuncture points around Feng Guoqing's bedside, and removed the needles after leaving them in for thirty seconds. While removing the needles, she carefully observed Feng Guoqing's eyes. At first, Feng Guoqing didn't move at all after the six needles. It was not until the seventh needle that Song Yun saw his eyeballs move under his eyelids.

After the eighth injection, Feng Guoqing's eyelids moved again, and then returned to normal.

Song Yun smiled. As long as there was a reaction, it was good. It proved that Feng Guoqing was not brain dead. As long as he was not brain dead, there was still a chance for him to wake up.

He didn't wake up for three years. It must be because the head injury was too severe and he didn't recover after three years.

Maybe you can try Xin Dan, which also has certain effects in treating brain diseases.

In fact, using advanced nutrient solution would be the best and fastest option.

It's just that the effectiveness of the advanced nutrient solution is easy to make people doubt it, and after using the advanced nutrient solution, the physical fitness and five senses will be greatly improved, which she cannot explain.

So she couldn't possibly use the advanced nutrient solution on someone she couldn't fully trust.

Even if it is a relative, she would not use it easily unless it is absolutely necessary.

There are some secrets that she hopes will remain secret forever.

After Song Yun finished receiving the needles, she said to Professor Liu, "Comrade Feng is still conscious, but the brain damage has prevented him from regaining consciousness. I have a medicine here that might be worth a try. It's specifically for treating unconsciousness. I don't know if it's effective, but you can give it a try. What do you think?"

Professor Liu didn't understand these things, but she completely trusted Song Yun. If she said she could try, then she would try.

"Try it, I'll listen to you. No matter what the outcome is, I'll be grateful to you and won't complain."

With Professor Liu's approval, Song Yun took out the Heart-Soothing Pills that had been put in the medicine box in advance, poured out a batch of pills, dissolved them in warm water, and then fed them into the patient through the tube that Professor Liu used to feed him.

After feeding Feng Guoqing the Heart Pill, Song Yun pressed Feng Guoqing's head for a while. It seemed like a simple head massage, just pressing a few circles of acupoints, but in fact, each press used internal Qi to dredge the acupoints around the brain. If there was blood stasis around the brain, this Qi massage could effectively disperse the blockage and activate the diseased nerves around the brain. It has many benefits overall.

After massaging his head, Song Yun also massaged Feng Guoqing's limbs.

Although Professor Liu took good care of him, muscle atrophy and degeneration were inevitable due to long-term disuse of his limbs. Even if he woke up, he would need a period of rehabilitation and exercise before he could stand up again.

While pressing, Song Yun explained to Professor Liu how to press most effectively.

Professor Liu was very attentive in his studies. When he pressed her hand, Song Yun seemed to feel Feng Guoqing's fingers move slightly.

However, the amplitude was very small, and Song Yun suspected that she had felt it wrong. After staring at it for a while, she found that the fingers had indeed not moved again, which made her even more suspicious. So she did not say anything, so as not to give people hope and then disappoint them, which is the most painful thing.

After teaching Professor Liu acupoint massage, it was time for Feng Guoqing to eat. Professor Liu brought a basin of hot water and asked Song Yun and Ziyi to wash their hands. Then she went to the kitchen and brought the chicken soup and millet porridge that had been cooked long ago, and fed it into Feng Guoqing's esophagus little by little through a tube.

Feng Guoqing cannot chew on his own, and his digestive ability has become very poor after lying in bed for a long time. He can only eat some easily digestible liquid food and eat small meals frequently to stay alive. It is impossible for him to have a balanced nutrition.

This is because Professor Liu took good care of the baby. If it were someone else who didn't take good care of him, he would have rotted away long ago and would not have survived until now.
